Description

台虎钳技术领域 Bench vice Technical field

本发明涉及一种台虎钳。 The invention relates to a bench vice.

背景技术 Background technique

传统的台虎钳固定安装在钳工工作台上，用来装夹被夹持工件，便于钳工对工件进行锉、锯等手工或机械加工。但是其夹紧大都采用丝杠螺母结构，在夹紧工件的过程中，需要操作者一只手扶被夹持工件，另一只手操作丝杆进行夹紧工件，但是采用丝杆螺母的结构，夹紧比较慢，不方便。而且在操作过程中，若被夹持工件较大，需要操作者两只手同时扶持的情况下，操作者就很难操作。 The traditional bench vise is fixedly mounted on the bench, which is used to clamp the workpiece to be clamped, so that the fitter can manually or mechanically machine the workpiece. However, most of the clamping uses the screw nut structure. In the process of clamping the workpiece, the operator needs to hold the workpiece by one hand, and the other hand operates the screw to clamp the workpiece, but the structure of the screw nut is adopted. , Clamping is slow and inconvenient. Moreover, in the operation process, if the workpiece to be clamped is large and the operator needs to support both hands at the same time, the operator is difficult to operate.

如图 2所示，台虎钳 30 包括固定在架体 38上的定导轨 40、相对定导轨 40移动的动导轨 42、以及定钳口 44和设置于动导轨 42上的动钳口 46。其中动导轨 42 沿着 E方向可滑动的设置在定导轨 46上。定钳口 46靠近操作者，固定设置在基架前部 36 或定导轨 40 的前端，也就是位于基架前部 36 和架体 38的连接处；动钳口 46 固定设置在动导轨 42的一端。 As shown in Fig. 2, the vise 30 includes a fixed rail 40 fixed to the frame 38, a movable rail 42 that moves relative to the fixed rail 40, and a fixed jaw 44 and a movable jaw 46 disposed on the movable rail 42. The movable rail 42 is slidably disposed on the fixed rail 46 in the E direction. The fixed jaw 46 is close to the operator and is fixedly disposed at the front end of the base frame 36 or the fixed rail 40, that is, at the joint of the front portion 36 of the base frame and the frame body 38; the movable jaw 46 is fixedly disposed on the moving rail 42 One end.

定钳口 44 包括用于与工件相接触的第一夹持面 48。动钳口 46包括用于与工件相接触的第二夹持面 50 , 其中第二夹持面 50背对动导轨 42设置。第一夹持面 48与第二夹持面 50相对设置，形成了用于夹持工件的第一夹持区域。 The fixed jaw 44 includes a first clamping surface 48 for contacting the workpiece. The movable jaw 46 includes a second clamping surface 50 for contacting the workpiece, wherein the second clamping surface 50 is disposed opposite the moving rail 42. The first clamping surface 48 is disposed opposite the second clamping surface 50 to form a first clamping region for holding the workpiece.

台虎钳 30还包括驱动机构 52、与驱动机构 52连接的操作件，其中操作件可操作地促使驱动机构 52驱动动钳口 46相对于定钳口 44移动。在本实施例中，操作件是脚踏组件 54。当然，操作件也可以是其它可以用手操作的其它操作元件。 The vise 30 also includes a drive mechanism 52, an operating member coupled to the drive mechanism 52, wherein the operating member operatively urges the drive mechanism 52 to move the movable jaw 46 relative to the fixed jaw 44. In the present embodiment, the operating member is the pedal assembly 54. Of course, the operating member can also be other operating elements that can be operated by hand.

在本实施例中，脚踏组件 54可枢转地与驱动机构 52连接。当然，脚踏组件 54也可以通过滑动地方式连接在驱动机构 52上。 In the present embodiment, the footrest assembly 54 is pivotally coupled to the drive mechanism 52. Of course, the footrest assembly 54 can also be slidably coupled to the drive mechanism 52.

如图 3和图 4所示，驱动机构 52包括与脚踏组件 54枢转连接的杠杆 58、与杠杆 58枢转连接并带有凸块 60的推进臂 62、设置在架体 38上的止挡件 64、设置在推进臂 62和杠杆 58之间的偏压件 78和设置在动导轨 42上的凹槽 66，其中凹槽 66沿动导轨 42的纵向设置，偏压件 78促使凸块 60始终朝向与凹槽 66啮合的方向。杠杆 58带动凸块 60在与凹槽 66啮合的状态和与凹槽 66脱开的状态之间移动。凸块 60处于啮合状态时，由于凸块 60与凹槽 66啮合，杠杆 58的枢转运动就会推动凸块 60带动动导轨 42移动。凸块 60 处于与凹槽 66的脱开状态，止挡件 64与推进臂 62接触用于止挡推进臂 62 枢转。 As shown in FIGS. 3 and 4, the drive mechanism 52 includes a lever 58 pivotally coupled to the pedal assembly 54, a pusher arm 62 pivotally coupled to the lever 58 and having a projection 60, disposed on the frame 38. a blocking member 64, a biasing member 78 disposed between the pusher arm 62 and the lever 58 and a recess 66 disposed on the movable rail 42, wherein the recess 66 is disposed along the longitudinal direction of the movable rail 42, and the biasing member 78 urges the bump 60 is always oriented in a direction that engages the groove 66. The lever 58 drives the projection 60 to move between a state of being engaged with the groove 66 and a state of being disengaged from the groove 66. When the projection 60 is in the engaged state, since the projection 60 engages with the recess 66, the pivotal movement of the lever 58 pushes the projection 60 to move the movable guide 42. The projection 60 is in a disengaged state with the recess 66, and the stopper 64 is in contact with the pusher arm 62 for pivoting the pusher arm 62.

杠杆 58通过枢转轴 56可转动地设置在架体 38上，从而杠杆 58在脚踏组件 54的驱动下围绕枢转轴轴线 57转动。 The lever 58 is rotatably disposed on the frame 38 by a pivot shaft 56 such that the lever 58 is rotated about the pivot axis 57 by the pedal assembly 54.

杠杆 58具有初始位置和最下限位置。在初始位置，如图 3所示，台虎钳 30处于初始状态，此时，凸块 60处于与凹槽 66脱开的状态，止挡件 64与推进臂 62接触用于止挡推进臂 62枢转；在最下限位置，如图 4所示，凸块 60处于与凹槽 66啮合的状态，杠杆 58 围绕枢转轴轴线 57枢转至最下限位置。 The lever 58 has an initial position and a lowermost limit position. In the initial position, as shown in Fig. 3, the vise 30 is in an initial state, at which time the projection 60 is in a state of being disengaged from the recess 66, and the stopper 64 is in contact with the propulsion arm 62 for stopping the propulsion arm 62. Pivoting; In the lowermost limit position, as shown in Fig. 4, the projection 60 is in a state of meshing with the groove 66, and the lever 58 is pivoted about the pivot axis 57 to the lowermost limit position.

在杠杆 58和架体 38之间设置有弹性元件 68 , 弹性元件 68提供将杠杆 58保持在初始位置的作用力。在本实施例中，弹性元件是拉簧 68 , 当然，该弹性元件还可以是压簧、扭簧等等。 An elastic member 68 is provided between the lever 58 and the frame 38, and the elastic member 68 provides a force for holding the lever 58 in the initial position. In the present embodiment, the elastic member is a tension spring 68. Of course, the elastic member may also be a compression spring, a torsion spring or the like.

杠杆 58 包括连接杆 70和与连接杆 70 固定连接的驱动杆 72 , 其中连接杆 70包括与推进臂 62连接的第一端 74和与第一端 74相对设置的第二端 76 , 弹性元件 68设置在架体 38和连接杆 70的第二端 76之间。 The lever 58 includes a connecting rod 70 and a drive rod 72 fixedly coupled to the connecting rod 70, wherein the connecting rod 70 includes a first end 74 coupled to the push arm 62 and a second end 76 disposed opposite the first end 74, the resilient member 68 Disposed between the frame 38 and the second end 76 of the connecting rod 70.

推进臂 62通过转轴 63可枢转的设置在连接杆 70上，在本实施例中，偏压件 78为扭簧，套设该转轴 63上。当然，在这里偏压件也还可以是压簧、拉簧或是其它能够提供推进臂 62枢转回复力的结构。 The pusher arm 62 is pivotally disposed on the connecting rod 70 via the rotating shaft 63. In the present embodiment, the biasing member 78 is a torsion spring that is sleeved on the rotating shaft 63. Of course, the biasing member may also be a compression spring, a tension spring or other structure capable of providing a pivoting restoring force of the propulsion arm 62.

推进臂 62的一端设有凸块 60，另一端设有可选择地与止挡件 64配合的止挡块 82。在初始位置，止挡块 82与止挡件 64配合，从而推进臂 62 不能够朝向与凹槽 66啮合的方向转动。 One end of the pusher arm 62 is provided with a projection 60, and the other end is provided with a stop block 82 that selectively engages with the stop member 64. In the initial position, the stop block 82 cooperates with the stopper 64 so that the push arm 62 cannot It is rotatable in a direction to engage the groove 66.

脚踏组件 54可枢转的设置在杠杆 58上。脚踏组件 54 包括连接段 84和脚踏板 86。其中连接段 84 的一端围绕第一轴线 88 可转动的连接在杠杆 58 上，脚踏板 86可调节地连接在连接段 84的另一端。脚踏板 86相对连接的在连接段 84纵长延伸方向上调节，从而脚踏板 86对工作台的位置发生变化，适应不同升高的操作者使用或固定在不同高度的工作台上使用。当然，脚踏板 86也可以与连接段 84—体成型。 The footrest assembly 54 is pivotally disposed on the lever 58. The footrest assembly 54 includes a connecting section 84 and a footrest 86. One end of the connecting section 84 is rotatably coupled to the lever 58 about a first axis 88, and the footrest 86 is adjustably coupled to the other end of the connecting section 84. The pedals 86 are relatively connected in the longitudinal extension of the connecting section 84 so that the position of the footrest 86 to the table changes to accommodate different raised operators or fixed to work stations of different heights. Of course, the pedal 86 can also be integrally formed with the connecting section 84.

再参见图 3，杠杆 58 处于初始位置，此时，台虎钳 30处于初始状态。工作时，踩下脚踏板 86 , 脚踏组件 54带动杠杆 58 围绕枢转轴轴线 57向下旋转，此时，推进臂 62在杠杆 58的作用下，向前移动，使得推进臂 62上的止挡块 82脱开与止挡件 64的配合，在扭簧 78的作用下，推进臂 62的凸块 60进入与凹槽 66啮合的状态，然后由于操作者通过脚踏板 86继续带动杠杆 58枢转运动至最下限位置，如图 4所示。在杠杆 58继续枢转的过程中，杠杆 58推动凸块 60带动动导轨 42向前推送一定距离，使得动钳口 46相对于定钳口 44移动。 Referring again to Figure 3, the lever 58 is in the initial position, at which point the vise 30 is in the initial state. In operation, the footrest 86 is depressed, and the pedal assembly 54 drives the lever 58 to rotate downward about the pivot axis 57. At this time, the pusher arm 62 is moved forward by the lever 58 to cause the stop block on the pusher arm 62. 82 is disengaged from engagement with the stop member 64. Under the action of the torsion spring 78, the projection 60 of the pusher arm 62 enters a state of engagement with the recess 66, and then the lever 58 is continuously pivoted by the operator through the footrest 86. Move to the lowest limit position, as shown in Figure 4. During the continued pivoting of the lever 58, the lever 58 pushes the projection 60 to move the guide rail 42 forward a distance such that the movable jaw 46 moves relative to the fixed jaw 44.

由于止挡件 64 与止挡块 82 配合，当杠杆 58***作做围绕枢转轴轴线 57做旋转运动时可以促使推进臂—62快速地脱开与止挡件 64的配合，从而使得推进臂 62上的凸块 60快速地与凹槽 66啮合。这样加快了动导轨 42的移动速度。 Since the stop member 64 cooperates with the stop block 82, the lever 58 can be urged to quickly disengage from the stop member 64 when the lever 58 is operated to perform a rotational movement about the pivot axis 57, thereby causing the pusher arm 62 to be engaged. The upper bump 60 quickly engages the groove 66. This speeds up the movement of the moving rail 42.

松开脚踏组件 54 , 在拉簧 68 的作用下，杠杆 58 围绕枢转轴轴线 57向上旋转，回复初始位置，此时，台虎钳 30回复到初始状态。推进臂 62在杠杆 58的作用下，向后移动，直到推进臂 62的止挡块 82与止挡件 64接触，此时，凸块 60与凹槽 66脱离。如此重复踩脚踏板 86及释放脚踏板 86，便可以将动导轨 42连同动钳口 46快速向前靠近定钳口 44，这样就能通过脚踏的方式迅速将放置于第一夹持区域内的工件夹紧。 The pedal assembly 54 is released, and under the action of the tension spring 68, the lever 58 is rotated upward about the pivot axis 57 to return to the initial position, at which time the vise 30 returns to the initial state. The pusher arm 62 is moved rearwardly by the lever 58 until the stop block 82 of the pusher arm 62 comes into contact with the stopper 64, at which time the projection 60 is disengaged from the recess 66. By repeatedly stepping on the footrest 86 and releasing the footrest 86, the moving rail 42 and the movable jaw 46 can be quickly moved forward to the fixed jaw 44, so that the first clamping can be quickly placed by the pedal. Workpiece clamping in the area.

驱动机构 52 具有两个状态。台虎钳 30 处于初始状态下，驱动机构 52 在第一状态，驱动机构 52脱离与动导轨 42啮合，此时凸块 60在止挡件 64 的作用下始终与凹槽 66脱开，如此操作动导轨 42就可以使动导轨 42快速相对于定导轨 40移动。而当驱动机构 52在第二状态，操作件***作地促使驱动机构 52 中的凸块 60与 EJ槽 66啮合，从而驱动动导轨 42稳速相对定导轨 40移动。 The drive mechanism 52 has two states. When the vice vise 30 is in the initial state, the driving mechanism 52 is in the first state, and the driving mechanism 52 is disengaged from the moving rail 42. At this time, the lug 60 is always disengaged from the groove 66 by the stopper 64, and thus the operation is performed. The moving rail 42 can move the moving rail 42 quickly relative to the fixed rail 40. While the drive mechanism 52 is in the second state, the operating member is operative to urge the projection 60 in the drive mechanism 52 into engagement with the EJ slot 66, thereby driving the movable rail 42 to move relatively constant relative to the fixed rail 40.

所以当操作者需要夹持工件时，可以根据工件的尺寸，首先在台虎钳 30 处于初始状态下，快速移动动导轨 42，使得动钳口 46的第二夹持面 50靠近工件；然后再按照上述的方法稳速的移动动导轨 42，使工件被夹持在第一夹持面 48和第二夹持面 50之间。 So when the operator needs to clamp the workpiece, it can be based on the size of the workpiece, first in the vise 30 In the initial state, the moving rail 42 is quickly moved so that the second clamping surface 50 of the movable jaw 46 is close to the workpiece; then the moving rail 42 is moved at a constant speed according to the above method, so that the workpiece is clamped at the first clamping. Between the face 48 and the second clamping surface 50.

当然，由于在台虎钳 30 处于初始状态下，此时，凸块 60 在止挡件 64 的作用下始终与凹槽 66脱开，操作者也可以根据需要，将动导轨 42完全拉出后换一下方向再安装于定导轨 40 上，如图 5 所示，这样可以扩大台虎钳 30的夹持范围。 Of course, since the bench vise 30 is in the initial state, at this time, the bump 60 is always disengaged from the groove 66 by the stopper 64, and the operator can also completely pull out the movable rail 42 as needed. The direction is changed and then mounted on the fixed rail 40, as shown in Fig. 5, which can enlarge the clamping range of the bench vise 30.

但是，为了防止在将动导轨 42 完全拉出后，误操作地踩踏脚踏板 86，而使推进臂 62上的凸块 60在扭簧 78的作用下向上转动，与架体 38或定导轨 40发生硬性碰撞。所以在推进臂 62上还设有限位销 65 , 如图 3和图 4所示。若将动导轨 42完全拉出后 , 误操作地踩踏脚踏板 86，凸块 60在扭簧 78 的作用下向上转动到一定位置后，限位销 65会与架体 38或定导轨 40接触，从而有效地防止了凸块 60与架体 38或定导轨 40发生硬性碰撞。 However, in order to prevent the pedal 86 from being erroneously operated after the moving rail 42 is completely pulled out, the projection 60 on the propulsion arm 62 is rotated upward by the torsion spring 78, with the frame 38 or the fixed rail. 40 hard collision occurred. Therefore, a limit pin 65 is also provided on the push arm 62, as shown in Figs. 3 and 4. If the moving rail 42 is completely pulled out, the foot pedal 86 is stepped by mistake, and the projection 60 is rotated upward to a certain position by the torsion spring 78, and the limiting pin 65 is in contact with the frame 38 or the fixed rail 40. Therefore, the bump 60 is hardly prevented from colliding with the frame 38 or the fixed rail 40.

再参见图 5，动钳口 46还包括用于与工件相接触的第三夹持面 90，其中第三夹持面 90朝向动导轨 42设置。当动导轨 42被完全拉出后换方向安装在定导轨 40上，第三夹持面 90与第一夹持面 48相对设置，形成用于夹持工件的第二夹持区域。而且第二夹持区域的夹持范围远大于第一夹持区域的夹持范围。 Referring again to Figure 5, the movable jaw 46 further includes a third clamping surface 90 for contacting the workpiece, wherein the third clamping surface 90 is disposed toward the moving rail 42. When the movable rail 42 is completely pulled out, it is mounted on the fixed rail 40 in a reversing direction, and the third clamping surface 90 is disposed opposite to the first clamping surface 48 to form a second clamping region for holding the workpiece. Moreover, the clamping range of the second clamping region is much larger than the clamping range of the first clamping region.

脚踏板 86可调节的连接在连接段 84上。在本实施例中，连接段 84为竖直连接段，脚踏板 86为与竖直连接段 84弯折连接的" L"形脚踏板。 "L"形脚踏板 86包括与竖直连接段 84连接的连接部分 92和用于操作者脚踏的脚踏部分 94 , 其中脚踏部分 94大致与连接部分 92垂直，方便操作者使力。而当操作者将脚放置到脚踏部分 94时，连接部分 92可以避免操作者在操作脚踏板 86的过程中脚碰撞到工作台 32的支撑脚 37上而产生伤害。 The foot pedal 86 is adjustably connected to the connecting section 84. In the present embodiment, the connecting section 84 is a vertical connecting section, and the footrest 86 is an "L" shaped foot pedal which is bent and connected to the vertical connecting section 84. The "L" shaped footrest 86 includes a connecting portion 92 that is coupled to the vertical connecting section 84 and a footrest portion 94 for the operator's foot, wherein the pedal portion 94 is substantially perpendicular to the connecting portion 92 for facilitating the operator's effort. . When the operator places the foot on the pedal portion 94, the connecting portion 92 can prevent the operator from colliding with the support leg 37 of the table 32 during the operation of the footrest 86 to cause injury.

连接部分 92上设有若干个螺纹孔 96。螺栓 98 穿过连接段 84上的孔可选择的与连接部分 92上的其中一个螺纹孔 96配合，用于调节脚踏板 86相对于连接段 84的距离。如此，操作者可以根据自己的身高或工作台 30的高度来调整脚踏部分 94相对于工作台 32之间的距离，使得脚踏部分 94处于最舒适的高度。 The connecting portion 92 is provided with a plurality of threaded holes 96. The bolt 98 passes through a hole in the connecting section 84 and is selectively engageable with one of the threaded holes 96 in the connecting portion 92 for adjusting the distance of the footrest 86 relative to the connecting section 84. Thus, the operator can adjust the distance between the pedal portion 94 relative to the table 32 according to his or her height or the height of the table 30 such that the pedal portion 94 is at the most comfortable height.

当动钳口 46处于所需的夹紧位置后，就可以通过设置在架体 38和杠杆 58之间的锁紧机构 1 00将动钳口 46的位置进行锁紧。 When the movable jaw 46 is in the desired clamping position, the position of the movable jaw 46 can be locked by the locking mechanism 100 disposed between the frame 38 and the lever 58.

如图 3，图 4和图 6所示，锁紧机构 1 00 包括枢轴连接于杠杆 58上的导柱 102、滑动设置在基架前部 36上的锁钮 104、连接在锁钮 104上的连杆 106、枢轴连接在基架前部 36的摆动座 108、套设有连杆 106上的弹簧 110。其中摆动座 108设有收容导柱 102 的收容孔 112，锁钮 104在将导柱 102与收容孔 112卡紧的锁紧位置和允许导柱 102相对于收容孔 112移动的释放位置之间移动。 As shown in Figures 3, 4 and 6, the locking mechanism 100 includes a guide pivotally coupled to the lever 58. The column 102, the lock button 104 slidably disposed on the front portion 36 of the pedestal, the connecting rod 106 connected to the locking button 104, the swinging seat 108 pivotally connected to the front portion 36 of the pedestal, and the connecting rod 106 Spring 110. The swinging seat 108 is provided with a receiving hole 112 for receiving the guiding post 102. The locking button 104 moves between a locking position for clamping the guiding post 102 and the receiving hole 112 and a releasing position for allowing the guiding post 102 to move relative to the receiving hole 112. .

导柱 102可枢转的连接在杠杆 58上，且导柱 102的旋转轴线与第一轴线 88平行或同轴设置。为了结构更加紧凑，操作更加方便，在本实施例中，导柱 102的旋转轴线与第一轴线 88重合。且导柱 102和脚踏板 86围绕同一根轴旋转。 The guide post 102 is pivotally coupled to the lever 58 and the axis of rotation of the guide post 102 is disposed parallel or coaxial with the first axis 88. In order to make the structure more compact and more convenient to operate, in the present embodiment, the axis of rotation of the guide post 102 coincides with the first axis 88. The guide post 102 and the foot pedal 86 rotate about the same axis.

导柱 102 包括与杠杆 58枢转连接的连接端和相对设置的自由末端。在自由末端上设有卡销 105。 The guide post 102 includes a connecting end pivotally coupled to the lever 58 and an oppositely disposed free end. A bayonet 105 is provided on the free end.

杠杆 58在初始位置和最下限位置之间移动，台虎钳 30上设有第一和第二限位机构。第一、第二限位机构主要用于将杠杆 58这两个位置限位。 The lever 58 is moved between an initial position and a lowermost limit position, and the first and second limit mechanisms are provided on the vise 30. The first and second limit mechanisms are mainly used to limit the two positions of the lever 58.

杠杆 58 处于初始位置，如图 3 所示，第一限位机构为固定设置在架体 38上限位块 107。当杠杆 58在拉簧 68的作用下，枢转至与限位块 107接触，这时杠杆 58在初始位置被限位。杠杆 58处于最下限位置，如图 4所示，第二限位机构包括设置在导柱 102的自由末端的卡销 105和摆动座 108的内表面。当杠杆 58被作用的围绕枢转轴的轴线 57作枢转运动，导柱 102被杠杆 58带动也围绕导柱 102的旋转轴线既枢转又向下运动，当导柱 102运动至卡销 105与摆动座 108的内表面相接触，这时杠杆 58在最下限位置被限位。 The lever 58 is in the initial position, as shown in Fig. 3, the first limiting mechanism is fixedly disposed on the upper limit block 107 of the frame body 38. When the lever 58 is pivoted to contact the stopper 107 by the tension spring 68, the lever 58 is restrained at the initial position. The lever 58 is at the lowermost limit position. As shown in Fig. 4, the second limiting mechanism includes a bayonet 105 disposed at the free end of the guide post 102 and an inner surface of the swinging seat 108. When the lever 58 is pivotally moved about the axis 57 about the pivot axis, the guide post 102 is driven by the lever 58 and also pivots and moves downward about the axis of rotation of the guide post 102, when the guide post 102 moves to the bayonet 105 and The inner surfaces of the swinging seats 108 are in contact, at which time the lever 58 is constrained at the lowermost limit position.

摆动座 108 的第一端通过枢轴 107 转动连接在基架前部 36上。收容孔 112 固定设置在摆动座 108的第二端。 The first end of the swinging seat 108 is rotatably coupled to the front portion 36 of the base frame via a pivot 107. The receiving hole 112 is fixedly disposed at the second end of the swinging seat 108.

在本实施例中，连杆 106卡设在锁钮 104的下端并被锁钮 104带动旋转。连杆 106通过锁轴 114与摆动座 108转动连接，且将弹簧 110套设于连杆 106 上，如此设计，使得当锁钮 104在释放位置，在弹簧 110的作用下，摆动座 108 设有收容孔 112 的第二端始终朝着非翘起的方向，也就是朝向地面的方向。当锁钮 104在锁紧位置，如图 7所示，在弹簧 110的作用下，摆动座 108 设有收容孔 112的第二端始终朝着翘起的方向。 In the present embodiment, the link 106 is engaged at the lower end of the lock button 104 and is rotated by the lock button 104. The connecting rod 106 is rotatably connected to the swinging seat 108 via the lock shaft 114, and the spring 110 is sleeved on the connecting rod 106. The design is such that when the locking button 104 is in the releasing position, the swinging seat 108 is provided by the spring 110. The second end of the receiving hole 112 is always oriented in a non-cocked direction, that is, in the direction toward the ground. When the lock button 104 is in the locked position, as shown in Fig. 7, under the action of the spring 110, the swing seat 108 is provided with the second end of the receiving hole 112 always facing the upward direction.

如图 3和图 4所示，此时锁钮 104保持在释放位置，在弹簧 110的作用下，摆动座 108设有收容孔 112的第二端始终朝着地面的方向，如此当脚踏板 86 围绕轴线旋转过程中，带动导柱 102在收容孔 112 中自由滑动。 As shown in FIG. 3 and FIG. 4, at this time, the lock button 104 is held in the release position. Under the action of the spring 110, the swing seat 108 is provided with the second end of the receiving hole 112 always facing the ground, so that when the pedal is used During the rotation around the axis, the guide post 102 is slid freely in the receiving hole 112.

为了防止操作者使力不当，而卡住导柱 102。在摆动座 108 上还设限位板 113。如图 7所示，当向下压下锁钮 104使其到达锁紧位置，锁钮 104带动连杆 106下移，销轴 114产生枢转，在弹簧 110的作用下，摆动座 108设有收容孔 112的第二端始终朝着翘起的方向，而摆动座 108向上挑起使得导柱 102 始终与收容孔 112的两个对角接触，如此，导柱 102的向上运动被限制，而只能向下运动；这时只需踩下脚踏板 86，使杠杆 58带动导柱 102 向下运动至最下限位置，此时，松开脚踏板 86，由于摆动座 108在弹簧 110的作用下始终朝着翘起的方向，这样导柱 102就会向上移动到一定位置而被收容孔 112 卡死，这样动导轨 42及其动钳口 46的位置就被锁定。 In order to prevent the operator from making a force, the guide post 102 is caught. A limit plate 113 is also provided on the swing seat 108. As shown in FIG. 7, when the lock button 104 is pressed down to the locked position, the lock button 104 drives the link 106 to move downward, and the pin shaft 114 is pivoted. Under the action of the spring 110, the swing seat 108 is provided. The second end of the receiving hole 112 is always oriented in the upward direction, and the swinging seat 108 is lifted upward so that the guide post 102 is always in contact with the two diagonals of the receiving hole 112, so that the upward movement of the guide post 102 is restricted, and Only the downward movement can be performed; at this time, only the foot pedal 86 is depressed, so that the lever 58 drives the guide post 102 to move downward to the lower limit position. At this time, the foot pedal 86 is released, because the swing seat 108 is under the action of the spring 110. Always in the direction of the tilting, the guide post 102 is moved upward to a certain position and is locked by the receiving hole 112, so that the position of the movable guide 42 and its movable jaw 46 is locked.

如果想要重新释放动导轨 42及其动钳口 46，只需要将锁钮 104向上抬起至释放位置（如图 3和图 4所示），摆动座 108处于朝向地面的位置。此时，踩下脚踏板 86，由于导柱 102 已从收容孔 112 中解锁，从而，导柱 102可以自由在收容孔 112 内滑动。 If it is desired to re-release the moving rail 42 and its movable jaw 46, it is only necessary to lift the locking button 104 up to the release position (as shown in Figures 3 and 4), and the swinging seat 108 is in a position facing the ground. At this time, the footrest 86 is depressed, and since the guide post 102 has been unlocked from the receiving hole 112, the guide post 102 can freely slide in the receiving hole 112.

如图 8和图 9所示，设置在工作台 32和架体 38之间的固定装置 120，该固定装置 120用于将台虎钳 30 固定在工作台 32上。 As shown in Figures 8 and 9, a fixture 120 is disposed between the table 32 and the frame 38 for securing the vice 30 to the table 32.

In the present embodiment, the fixing plate 122 includes two side plates 132 and a mounting plate 134 connecting the side plates 132, and the mounting plate 134 is substantially U-shaped. Mounting holes 128 and mating holes 130 are provided on the mounting plate 134. The screw 136 is fixed to the table 32 through the side plates 132, so that the receiving space 138 is formed between the U-shaped mounting plate 134 and the work table 32.

紧固件 124 包括止挡部 140、螺纹部 142 以及连接止挡部 140和螺纹部 142的连接部 144，其中止挡部 140的横截面积大于连接部 144的横截面积；连接部 144的横截面与安装孔 128的横截面相匹配。 The fastener 124 includes a stopping portion 140, a threaded portion 142, and a connecting portion 144 connecting the stopping portion 140 and the threaded portion 142, wherein the cross-sectional area of the stopping portion 140 is larger than the cross-sectional area of the connecting portion 144; The cross section matches the cross section of the mounting hole 128.

安装时，将紧固件 124的止挡部 140穿过配合孔 130并位于收容空间 138 内，再移动紧固件 124将连接部 144与安装孔 128相配合，紧固件 124穿过架体 38上的孔，使螺纹部 142与旋钮 126螺纹连接，如此，将台虎钳 30固定在工作台上。 During installation, the stop portion 140 of the fastener 124 passes through the mating hole 130 and is located in the receiving space 138, and then the fastener 124 is moved to cooperate with the mounting hole 128, and the fastener 124 passes through the frame. The hole in the 38, the threaded portion 142 is screwed to the knob 126, thus, the bench vise 30 is fixed to the table.

台虎钳 30具有重心。为了将台虎钳 30可以稳定、省力的安装在工作台 32上，将台虎钳 30安装在工作台 32上后，台虎钳 30的重心在水平面上的投影位于工作台 32在水平面的投影范围内。 The vise 30 has a center of gravity. In order to mount the vise 30 on the table 32 in a stable and labor-saving manner, after the table vise 30 is mounted on the table 32, the projection of the center of gravity of the vise 30 on the horizontal plane is located on the horizontal plane of the table 32. Within the scope.

为了使台虎钳 30可以快速安装到工作台 32上，在基架 34和工作台 32 之间设有定位机构。 In order to allow the bench vise 30 to be quickly mounted to the table 32, the pedestal 34 and the table 32 There is a positioning mechanism between them.

定位机构包括设置在工作台 32上的第一定位板 152和设置在架体 38上的第二定位板 154，其中第一、第二定位板 152和 154其中之一上设有定位孔，第一、第二定位板 152和 154其中另一个上设有与定位孔配合的凸起。 The positioning mechanism includes a first positioning plate 152 disposed on the table 32 and a second positioning plate 154 disposed on the frame body 38, wherein one of the first and second positioning plates 152 and 154 is provided with a positioning hole, 1. The second positioning plates 152 and 154 are provided with protrusions that cooperate with the positioning holes.

在本实施例中，第一定位板 152大致为 "L"形，具有两个相互垂直的側板 155和 156, 其中侧板 155通过螺钉固定在工作台 32的工作台面 33上，侧板 156通过螺钉固定在工作台 32的侧边 35上。且在侧板 156上设有定位孔 160 (如图 1 所示）。 In the present embodiment, the first positioning plate 152 has a substantially "L" shape and has two mutually perpendicular side plates 155 and 156, wherein the side plates 155 are fixed to the table surface 33 of the table 32 by screws, and the side plates 156 pass Screws are secured to the side edges 35 of the table 32. A positioning hole 160 (shown in Fig. 1) is disposed on the side plate 156.

第二定位板 154大致为 "L"形，具有两个相互垂直的侧板 157和 158，其中侧板 157通过螺钉固定在架体 38上。在本实施例中，第二定位板 154安装在架体 38大致三分之一处，且靠近基架前部 36。拉簧 68—端连接在第二定位板 154上，另一端连接在连接杆 70的第二端 76上。如此，弹簧 68可以快速使杠杆 58回复到初始位置。在侧板 158上设有与定位孔 160相配合的凸起 162。该凸起 162可以通过冲压形成。 The second positioning plate 154 has a substantially "L" shape and has two mutually perpendicular side plates 157 and 158, wherein the side plates 157 are fixed to the frame body 38 by screws. In the present embodiment, the second positioning plate 154 is mounted approximately one-third of the frame 38 and adjacent to the front portion 36 of the base frame. The tension spring 68 is connected to the second positioning plate 154, and the other end is connected to the second end 76 of the connecting rod 70. Thus, the spring 68 can quickly return the lever 58 to the initial position. A projection 162 is provided on the side plate 158 to cooperate with the positioning hole 160. The projection 162 can be formed by stamping.

安装台虎钳 30 时，首先使凸起 162 与定位孔 160 配合，将第二定位板 154贴合在第一定位板 152上，再通过固定装置 120将台虎钳 30 固定在工作台 32—上。 — ― When the vise 30 is installed, the protrusion 162 is firstly engaged with the positioning hole 160, the second positioning plate 154 is attached to the first positioning plate 152, and the table vise 30 is fixed to the table 32 by the fixing device 120. on. — ―

为了使得台虎钳 30的结构更加紧凑，且杠杆 58有足够的力量驱使动导轨 42相对定导轨 40滑动。如图 10和图 11所示，驱动杆 72 包括第一折弯部 164, 第一折弯部 164朝向工作台 32方向弯折，且在杠杆 58处于初始位置或最下限位置时，第一折弯部 164位于工作台 32之外，这样，就可以避免杠杆 58在转动过程中与工作台 32碰撞。 In order to make the structure of the vise 30 more compact, the lever 58 has sufficient force to drive the movable rail 42 to slide relative to the fixed rail 40. As shown in FIGS. 10 and 11, the drive rod 72 includes a first bent portion 164, and the first bent portion 164 is bent toward the table 32, and when the lever 58 is at the initial position or the lowermost limit position, the first fold The bend 164 is located outside of the table 32 so that the lever 58 can be prevented from colliding with the table 32 during rotation.

为了使得杠杆 58具有较强的刚性。杠杆 58还包括与第一折弯部 164背对设置的第二折弯部 166, 第二折弯部 166背向工作台 32方向弯折，且与脚踏组件 54连接。 In order to make the lever 58 have a strong rigidity. The lever 58 further includes a second bent portion 166 disposed opposite the first bent portion 164, the second bent portion 166 being bent away from the table 32 and coupled to the footrest assembly 54.

如此设计杠杆 58，可以在有效的空间内，增加杠杆 58 的有效长度，满足杠杆 58有足够的力量驱使动导轨 42相对定导轨 40移动。在这里，有效长度为脚踏组件 54的旋转轴线（同第一轴线 88 ) 与杠杆 58 的枢转轴 56的轴线 57之间的距离 H。有效长度的选取和脚踏组件 54的关系为：脚踏组件 54 的纵长延伸长度与有效长度的比值大于 1, 其中较佳的比值范围可以为 1.5 至 3, 优选地的比值为 1.8至 2.5。 The lever 58 is designed such that the effective length of the lever 58 can be increased in an effective space, and the lever 58 has sufficient force to drive the movable rail 42 relative to the fixed rail 40. Here, the effective length is the distance H between the axis of rotation of the pedal assembly 54 (same as the first axis 88) and the axis 57 of the pivot axis 56 of the lever 58. The relationship between the effective length selection and the pedal assembly 54 is: The ratio of the lengthwise extension of the pedal assembly 54 to the effective length is greater than one, wherein a preferred ratio may range from 1.5 to 3, preferably a ratio of 1.8 to 2.5. .

如图 10所示，杠杆 58在初始位置，脚踏组件 54 围绕的第一轴线 88在工作台面 33上的投影位于基架前部 36 内。且该第一轴线 88基本平工作台面 33 平齐；如图 1 1 所示，杠杆 58在最下限位置，脚踏组件 54 围绕的第一轴线 88在工作台面 33上的投影位于架体 38 内。 As shown in Figure 10, the lever 58 is in the initial position, and the first axis 88 around the pedal assembly 54 is The projection on the work surface 33 is located within the front portion 36 of the pedestal. And the first axis 88 is substantially flush with the work surface 33; as shown in FIG. 11, the projection 58 of the lever 58 is at the lowermost limit position, and the projection of the first axis 88 around the pedal assembly 54 on the work surface 33 is located in the frame 38. .

脚踏组件 54—般设置在工作台面 33之下，特别是脚踏板 86位于工作台面 33 之下，脚踏部分 94 靠近地面位置。为了操作更加舒适，脚踏组件 54 的选取与架体关系为：脚踏组件 54的纵长延伸的长度与架体 38纵长延伸的长度的比值大于 1，其中较佳的比值范围可以为 1 至 2.5，优选地的比值为 1 至 1 .5。 The footrest assembly 54 is generally disposed below the work surface 33, particularly the footrest 86 is located below the work surface 33, and the footrest portion 94 is near the ground. For more comfortable operation, the selection of the pedal assembly 54 is related to the frame body: the ratio of the length of the longitudinal extension of the footrest assembly 54 to the length of the longitudinal extension of the frame body 38 is greater than 1, wherein a preferred ratio range may be one. To 2.5, a preferred ratio is from 1 to 1.5.

再参照图 1 0和图 1 1 , 第一夹持面 48位于工作台 32之外。因此，台虎钳 30在夹持工件时可以不会受工作台 32的影响，而扩大了夹持工件的范围。如图 1 2所示，如遇到较长工件 200时，可以将工件夹持，且还可以借助于地面，使得长工件更加稳定被夹持。 Referring again to Figures 10 and 11, the first clamping surface 48 is located outside of the table 32. Therefore, the tongs 30 can be unaffected by the table 32 while holding the workpiece, and the range in which the workpiece is held is enlarged. As shown in Fig. 12, when a long workpiece 200 is encountered, the workpiece can be clamped, and the long workpiece can be clamped more stably by means of the ground.

为了使得在操作脚踏板 86时可以比较平稳，或是为了避免由于操作者的使力不当而使得脚踏板 86与工作台 32的支撑腿 37之间发生硬性碰撞，台虎钳 30还设有导向装置 1 70。本实施例中，导向装置 1 70设置于脚踏组件 54 和工作台 32之间，用于引导脚踏组件 54做直线运动。当然，导向装置 170 也可以设置于脚踏组件 54和基架 34-之间，另 -外，也可设置为 ^导脚踏组件 54做弧形运动。在下面的实施例中会做详细介绍。 In order to make the pedals 86 relatively smooth when operating the pedals 86, or to avoid a hard collision between the footrests 86 and the support legs 37 of the table 32 due to the operator's improper force, the bench vise 30 is also provided. There is a guiding device 1 70. In this embodiment, the guiding device 170 is disposed between the pedal assembly 54 and the table 32 for guiding the pedal assembly 54 to perform linear motion. Of course, the guiding device 170 can also be disposed between the pedal assembly 54 and the base frame 34-, and can also be disposed to guide the pedal assembly 54 to perform an arcuate motion. This will be described in detail in the following embodiments.

导向装置 1 70引导脚踏组件 54做直线运动，使得脚踏组件 54在运动过程中在水平方向上距离基架前部 36最远的端点与基架前部 36之间的距离恒定，进而脚踏组件 54在运动过程中在水平方向上距离基架前部 36最远的端点与工作台 32之间的距离同样保持恒定，从而导向装置 1 70对脚踏组件实现稳定导向，避免了脚踏组件 54与工作台 32之间的硬性碰撞。 The guiding device 1 70 guides the pedal assembly 54 in a linear motion such that the distance between the end point of the footrest assembly 54 that is furthest from the base front portion 36 in the horizontal direction and the front portion 36 of the base frame is constant during the movement, and thus the foot The distance between the end point of the tread assembly 54 that is furthest from the front portion 36 of the pedestal in the horizontal direction and the table 32 is also kept constant during the movement, so that the guiding device 170 achieves a stable guiding of the pedal assembly, avoiding pedaling.

如图 1 3所示，导向装置 1 70 包括设置在脚踏板 86和工作台 32两者之一上的配合件 1 72和设置在脚踏板 86和工作台 32两者另一个上的导轨 1 74„ 配合件 172 固定安装在脚踏部分 94 上，具有与导轨 1 74配合的配合面 1 76。在本实施例中，该配合面 1 76为半圓形。当然，配合面也可以是方形等其它形状。 As shown in FIG. 13, the guiding device 1 70 includes a fitting member 172 disposed on one of the footrest 86 and the table 32, and a guide rail disposed on the other of the footrest 86 and the table 32. 1 74 „ The fitting 172 is fixedly mounted on the pedal portion 94 and has a mating surface 1 76 that cooperates with the guide rail 1 74. In this embodiment, the mating surface 1 76 is semi-circular. Of course, the mating surface may also be Other shapes such as squares.

导轨 1 74 固定设置在工作台的支撑腿 37上，当操作脚踏板时，半圓形的配合面 1 76沿导轨 1 74滑动。从而使得脚踏板 86在运动过程中可以平稳枢转，且也避免了脚踏板 86与工作台 32之间的硬性碰撞。当然，由于台虎钳 30可以安装在不同高度或不同宽度的工作台上，该配合件 1 72可调节的安装在脚踏部分 94上。 The guide rails 1 74 are fixedly disposed on the support legs 37 of the table, and when the foot pedals are operated, the semi-circular mating faces 1 76 slide along the guide rails 1 74. This allows the footrest 86 to pivot smoothly during movement and also avoids a hard collision between the footrest 86 and the table 32. Of course, since the bench vise 30 can be mounted on a table of different height or width, the fitting member 172 is adjustably mounted on the pedal portion 94.

与现有技术比较，本发明解决了传统台虎钳夹持速度慢、操作不方便的技术问题。而且相对于传统的台虎钳，本发明的台虎钳 30的整体体积、重量均没有明显增加，甚至还减轻了整体得重量。台虎钳 30 的整体重量小于 9 千克。台虎钳 30的整体尺寸小于 520 X 240 X 1 90立方毫米。如此设置，使台虎钳 30体积和重量都较小，便于使用者搬运，给使用者带来了便利。 Compared with the prior art, the present invention solves the technical problem that the conventional vise has a slow clamping speed and is inconvenient to operate. Moreover, compared with the conventional bench vice, the overall size and weight of the bench vise 30 of the present invention are not significantly increased, and the overall weight is even reduced. The overall weight of the vise 30 is less than 9 kg. The overall size of the vise 30 is less than 520 X 240 X 1 90 cubic millimeters. With this arrangement, the vise 30 is small in size and weight, and is convenient for the user to carry, which brings convenience to the user.

In the preferred embodiment, the foot pedal 228 is an "L" shaped foot pedal 228 that is bently coupled to the vertical connecting section 226. The "L" shaped foot pedal 228 includes a connecting portion 230 coupled to the vertical connecting section 226 and a foot portion 232 for the operator's foot, wherein the foot portion 232 is substantially perpendicular to the connecting portion 230 for facilitating operator effort . When the operator places the foot on the pedal portion 232, the connecting portion 230 can prevent the operator from colliding with the support foot of the table 208 during the operation of the foot pedal 228 to cause injury.

连接部分 230上设有若干个孔 234。螺栓（未图示）穿过竖直连接段 226 上的孔可选择的与连接部分 230上的其中一个孔 234配合，用于调节脚踏板 228相对于竖直连接段 226 的距离。如此，操作者可以根据自己的身高或工作台 208的高度来调整脚踏部分 232相对于工作台 208之间的距离，使得脚踏部分 232处于最舒适的高度。 The connecting portion 230 is provided with a plurality of holes 234. A bolt (not shown) through the aperture in the vertical connecting section 226 is selectively engageable with one of the apertures 234 in the connecting portion 230 for adjusting the distance of the foot pedal 228 relative to the vertical connecting section 226. Thus, the operator can adjust the distance between the tread portion 232 relative to the table 208 based on his or her height or the height of the table 208 such that the tread portion 232 is at the most comfortable height.

本优选实施例中，第一连接段 224背向工作台 208方向与竖直连接段 226 弯折连接，从而使得台虎钳结构紧凑。 - 配合件 21 8设置于竖直连接段 226上，当然，配合件 21 8也可以设置于脚踏板 228上。 In the preferred embodiment, the first connecting section 224 is bent away from the vertical connecting section 226 in a direction away from the table 208, thereby making the bench vise compact. - The fitting member 21 8 is disposed on the vertical connecting portion 226. Of course, the fitting member 218 can also be disposed on the foot pedal 228.

配合件 2 1 8设置为销轴，为减少加工成本，可采用标准螺栓。当然，如本领域普通技术人员所知，配合件 21 8也可以设置为滚轮等。 The fitting 2 1 8 is set as a pin. To reduce the machining cost, standard bolts can be used. Of course, as is known to those skilled in the art, the fitting member 218 can also be provided as a roller or the like.

竖直连接段 226上固定设有套筒 236 ,套筒 236可焊接于竖直连接段 226 上。配合件 2 1 8可拆卸地设于套筒 236中，如此可方便配合件 21 8和导轨 220 的配合安装。 A sleeve 236 is fixed to the vertical connecting section 226, and the sleeve 236 can be welded to the vertical connecting section 226. The fitting member 2 1 8 is detachably disposed in the sleeve 236, so that the fitting member 21 8 and the guide rail 220 can be easily fitted.

当然也可以在竖直连接段 226上设置通孔（未图示），把配合件 21 8穿过上述通孔和导轨 220即可。 It is of course also possible to provide a through hole (not shown) in the vertical connecting section 226, and the fitting member 21 8 is passed through the through hole and the guide rail 220.

如图 1 7所示，基架 206上设有支撑件 238 , 导轨 220设置于支撑件 238 上。本优选实施例中，支撑件 238通过螺钉 240可拆卸地连接于基架 206上 , 这样，当运输或存储台虎钳时，可把支撑件 238从基架 206上拆下，减小了存储空间和节约了运输成本。将导轨 220通过支撑件 238安装在基架 206上，可以不受工作台 208的影响而实现稳定导向，使得操作更加方便。支撑件 238设置为 U型，包括第一侧板 242、与第一侧板 242相对设置的第二側板 244、连接第一侧板 242和第二侧板 244的连接板 246，为提高导向稳定性，导轨 220设置为两个，分别设置在第一侧板 242和第二側板 244 上。 As shown in FIG. 17, the base frame 206 is provided with a support member 238, and the guide rail 220 is disposed on the support member 238. In the preferred embodiment, the support member 238 is detachably coupled to the base frame 206 by screws 240 such that the support member 238 can be removed from the base frame 206 when transporting or storing the table vise, reducing storage. Space and savings in transportation costs. Mounting the guide rail 220 on the base frame 206 through the support member 238 can achieve stable guidance without being affected by the work table 208, which makes the operation more convenient. The support member 238 is disposed in a U shape, and includes a first side plate 242, a second side plate 244 disposed opposite to the first side plate 242, and a connecting plate 246 connecting the first side plate 242 and the second side plate 244 for improving guiding stability. The guide rails 220 are disposed in two, and are disposed on the first side plate 242 and the second side plate 244, respectively.

竖直连接段 226位于第一侧板 242和第二側板 244之间，这样，使得脚踏组件 204在运动过程中更加平稳。当踩下脚踏板 228时，杠杆 229和脚踏组件 204可被收容于支撑件所形成的 U型空间中。 The vertical connecting section 226 is located between the first side panel 242 and the second side panel 244 such that the pedal assembly 204 is more stable during motion. When the foot pedal 228 is depressed, the lever 229 and the pedal assembly 204 can be received in the U-shaped space formed by the support member.

当进行配合件 21 8与导轨 220的配合安装时，首先通过螺钉 240把支撑件 238 固定于基架 206上，然后把脚踏组件 204的竖直连接段 226置于第一侧板 242和第二侧板 244之间，并使套筒 236的中空部与导轨 220对齐，最后让配合件 21 8 穿过第一侧板 242的导轨 220、套筒 236和第二側板 244上的导轨，配合件 21 8穿出的端部与螺母 248配合，从而防止配合件 21 8与导轨 220的脱开。另外，配合件 21 8上还穿设有止挡垫圏 250 , 以防止配合件 21 8的另一端与导轨 220脱开。 When the fitting member 218 is fitted to the guide rail 220, the support member 238 is first fixed to the base frame 206 by the screw 240, and then the vertical connecting portion 226 of the pedal assembly 204 is placed on the first side plate 242 and the Between the two side plates 244, the hollow portion of the sleeve 236 is aligned with the guide rail 220, and finally the fitting member 21 8 is passed through the guide rail 220 of the first side plate 242, the sleeve 236 and the guide rail on the second side plate 244 to cooperate The end of the member 21 8 is engaged with the nut 248 to prevent the fitting member 218 from being disengaged from the guide rail 220. In addition, the mating member 218 is also provided with a stop pad 250 to prevent the other end of the engaging member 218 from being disengaged from the guide rail 220.

本优选实施例中，配合件 21 8设置于竖直连接段 226面对工作台 208的侧边 252上，从而使得脚踏组件 204在运动过程中，操作者的腿不会碰到支撑件 238，提高了安全性。 - - 另外，为减少脚踏组件 204在运动过程中，配合件 21 8与导轨 220之间的摩擦，配合件 21 8与导轨 220之间设有橡胶圏 254。 In the preferred embodiment, the mating member 218 is disposed on the side edge 252 of the vertical connecting section 226 facing the table 208 such that the operator's legs do not touch the support member 238 during movement of the pedal assembly 204. , improved security. In addition, in order to reduce the friction between the fitting member 218 and the guide rail 220 during the movement of the pedal assembly 204, a rubber 254 254 is disposed between the fitting member 218 and the guide rail 220.

当操作脚踏组件 204时，配合件 2 1 8沿导轨 220滑动。从而使得脚踏组件 204在运动过程中可以平稳枢转，且也避免了脚踏板 228与工作台 208之间的硬性碰撞。 When the pedal assembly 204 is operated, the mating member 2 1 8 slides along the guide rail 220. This allows the pedal assembly 204 to pivot smoothly during motion and also avoids hard collisions between the foot pedal 228 and the table 208.

当动钳口 2 1 4处于所需的夹紧位置后、就可以通过锁紧机构 256将动钳口 2 1 4的位置进行锁紧。 After the movable jaw 2 1 4 is in the desired clamping position, the position of the movable jaw 2 1 4 can be locked by the locking mechanism 256.

如图 16和 1 8所示，本实施例中，锁紧机构 256与第一实施例的不同为，锁紧机构 256的导柱 258具有与收容孔 260配合的弧形部 262 ,使得锁钮 264 从释放位置（双点划线）到锁紧位置的移动行程 N仅为 44mm , 就能卡紧或释放导柱 258 , 而现有技术中的移动行程至少为 60mm。因此，导柱 258设置与收容孔 260配合的弧形部 262 , 大大缩小了锁钮 264的锁紧或解锁行程，使得该夹具操作方便。同时，大大提高了导柱 258的自锁效果。当然，该锁紧机构 256中，具有弧形部 262的导柱 258同样适用于其它夹具装置，如虎钳等。另外，当导柱 258处于相对于收容孔 260可移动的释放位置时，导柱 258 与收容孔 260的接触面积较小，从而减小了导柱 258的磨损，提高了锁紧机构 256的寿命。 As shown in FIGS. 16 and 18, in the present embodiment, the locking mechanism 256 is different from the first embodiment in that the guide post 258 of the locking mechanism 256 has an arcuate portion 262 that cooperates with the receiving hole 260, so that the locking button 264 The movement stroke N from the release position (two-dot chain line) to the locking position is only 44 mm, so that the guide post 258 can be clamped or released, whereas the prior art movement stroke is at least 60 mm. Therefore, the guide post 258 is provided with an arc portion 262 that cooperates with the receiving hole 260, which greatly reduces the locking or unlocking stroke of the lock button 264, so that the jig is convenient to operate. At the same time, the self-locking effect of the guide post 258 is greatly improved. Of course, in the locking mechanism 256, the guide post 258 having the curved portion 262 is also suitable for other clamp devices, such as a vise. In addition, when the guide post 258 is in a release position movable relative to the receiving hole 260, the contact area of the guide post 258 with the receiving hole 260 is small, thereby reducing the wear of the guide post 258 and improving the life of the locking mechanism 256. .

弧形部 262的圆心 266 (见图 1 5 ) 位于面对定钳口 2 16的一侧。 The center 266 of the curved portion 262 (see Fig. 15) is located on the side facing the fixed jaw 2 16 .

弧形部 262 的半径等于杠杆 229绕基架枢转的轴线 270至脚踏组件 204 绕杠杆 229枢转的轴线 272之间的距离。如此，使得踩踏脚踏组件 204时，杠杆 229绕基架 206的枢转更顺畅。 The radius of the curved portion 262 is equal to the distance between the axis 270 of the lever 229 pivoting about the base frame 270 to the axis 272 about which the pedal assembly 204 pivots about the lever 229. Thus, when the pedal assembly 204 is stepped on, the pivoting of the lever 229 about the base 206 is smoother.

另外，弧形部 262 的半径也可设计成大于或等于 276mm , 同时不大于 In addition, the radius of the curved portion 262 can also be designed to be greater than or equal to 276 mm, and not greater than

402mm。如此，使得该夹具不但结构紧凑，而且杠杆 229绕基架 206的枢转顺畅。 402mm. Thus, the jig is not only compact, but also the pivoting of the lever 229 about the base frame 206 is smooth.

导柱 258可枢转的连接在杠杆 229上，且导柱 258的旋转轴线与第一轴线 272平行或同轴设置。为了结构更加紧凑，操作更加方便，在本实施例中，导柱 258的旋转轴线与脚踏组件 204绕杠杆 229枢转的轴线 272重合。且导柱 258和脚踏组件 204围绕同一根轴旋转。 The guide post 258 is pivotally coupled to the lever 229, and the axis of rotation of the guide post 258 is disposed parallel or coaxial with the first axis 272. In order to make the structure more compact and more convenient to operate, in the present embodiment, the axis of rotation of the guide post 258 coincides with the axis 272 of the pedal assembly 204 pivoting about the lever 229. And the guide post 258 and the pedal assembly 204 rotate about the same axis.

导柱 258 包括与杠杆 229枢转连接的连接端和相对设置的自由末端。在自由末端上设有卡销 273。 The guide post 258 includes a connecting end pivotally coupled to the lever 229 and an oppositely disposed free end. A bayonet 273 is provided on the free end.

如图 1 7和 1 8所示，设置在工作台 208和基架 206之间的固定装置 274 , 该固定装置 274—用于将台虎钳固定在工作台 208上。 As shown in Figures 17 and 18, a fixture 274 is provided between the table 208 and the base frame 206 for securing the bench vise to the table 208.

固定装置 274 包括设置在工作台 208上的固定板 276、焊接于固定板 276 上的螺母 278、与螺母 278螺纹配合的螺杆 280及固定设置于螺杆 280端部的旋钮 282。 The fixture 274 includes a retaining plate 276 disposed on the table 208, a nut 278 welded to the retaining plate 276, a screw 280 threadedly engaged with the nut 278, and a knob 282 fixedly disposed at the end of the screw 280.

为了使台虎钳可以快速安装到工作台 208上，在基架 206和工作台 208 之间设有定位机构。 In order to allow the bench vise to be quickly mounted to the table 208, a positioning mechanism is provided between the base frame 206 and the table 208.

定位机构包括设置在工作台 208上的第一定位板 284和设置在架体 285 上的第二定位板 286 , 其中第一、第二定位板 284和 286其中之一上设有定位孔，第一、第二定位板 284和 286其中另一个上设有与定位孔配合的凸起。 The positioning mechanism includes a first positioning plate 284 disposed on the table 208 and a second positioning plate 286 disposed on the frame 285, wherein one of the first and second positioning plates 284 and 286 is provided with a positioning hole, 1. The other of the second positioning plates 284 and 286 is provided with a protrusion that cooperates with the positioning hole.
