Description
本发明属于打孔技术领域，尤其涉及一种钻头直径可变的打孔机构。The invention belongs to the field of punching technology, and in particular relates to a punching mechanism with a variable diameter of a drill bit.
目前打孔常采用固定直径的钻头，不同的打孔孔径使用不同的钻头。对于多个小孔钻孔，如果能够接受换钻头的时间和工作强度的话带上所需的钻头还是比较方便的。但是对于所钻的孔直径较大时，所需的钻头的直径较大、重量很重，对于同时钻多个大孔径的孔时，带上所需要的多个大孔径的钻头将耗费很多的体力和时间，这往往是不能容忍的，所以设计一种钻头直径可变的打孔机构将是非常有必要的。At present, drills of fixed diameter are often used for punching, and different drill holes are used for different punching holes. For multiple small hole drilling, it is convenient to carry the required drill bit if it is acceptable to change the time and work intensity of the drill bit. However, when the diameter of the drilled hole is large, the required drill bit has a large diameter and a heavy weight. When drilling a plurality of large-aperture holes at the same time, it takes a lot of time to carry a plurality of large-diameter drill bits required. Physical strength and time, which are often intolerable, it is necessary to design a perforating mechanism with a variable diameter of the drill bit.

相对于传统的打孔技术，本发明中第一支板、筒轴、第二齿轮、第二支板组成一个旋转整体，第一螺旋壁随着第二支板旋转，内轴、离心板固定在一起，内轴随着离心板围绕内轴轴线的旋转而旋转，内轴与筒轴之间具有涡卷弹簧，内轴与筒轴之间的转速或者相位差不同，涡卷弹簧将会被扭转压缩；当第一支板在筒轴带动下旋转，第二转轮将会在第一螺旋壁轨道中做离心螺旋运动，第二转轮会从第一螺旋壁的内始端向外终端运动，运动中通过第二转轮上的第二滑块与离心板的第一滑槽配合带动离心板围绕筒轴轴线旋转；之后离心板带动内轴旋转，因为离心板通过了转轮带动，转轮的运动在第一螺旋壁和离心力共同作用下运动，转轮与第一螺旋壁是具有相对运动的，离心板与第一螺旋壁的旋转将产生相位差，使得内轴与和筒轴之间产生相位差，相位差导致涡卷弹簧被压缩扭转，涡卷弹簧的反作用力抑制相位差的产生，当涡卷弹簧的抑制力、离心板受到的转轮离心力运动所产的力达到平衡时，内轴与筒轴同步旋转。筒轴获得的速度越大，第二转轮的离心力越大，第二转轮沿第一螺旋壁轨道运动中离筒轴的轴线距离越大，离心板相对与筒轴的相位差越大，涡卷弹簧就需要较大的压缩形变才能够使内轴与筒轴在较大的相位差下旋转达到平衡；被压缩的涡卷弹簧在筒轴停止运动时能量释放，通过带动内轴、第一滑槽、第一滑块对第二转轮进行复位；Compared with the conventional punching technology, the first support plate, the cylindrical shaft, the second gear and the second support plate form a rotating whole body, and the first spiral wall rotates with the second support plate, and the inner shaft and the centrifugal plate are fixed. Together, the inner shaft rotates with the rotation of the centrifugal plate about the inner shaft axis, and there is a scroll spring between the inner shaft and the cylinder shaft, and the rotational speed or phase difference between the inner shaft and the cylinder shaft is different, and the scroll spring will be Torsional compression; when the first support plate rotates under the rotation of the cylinder shaft, the second rotation wheel will perform centrifugal spiral motion in the first spiral wall track, and the second rotation wheel will move from the inner beginning end to the outer end end of the first spiral wall During the movement, the second sliding block on the second rotating wheel cooperates with the first sliding slot of the centrifugal plate to drive the centrifugal plate to rotate around the axis of the cylindrical shaft; then the centrifugal plate drives the inner shaft to rotate, because the centrifugal plate is driven by the rotating wheel, and the rotating plate is rotated. The movement of the wheel moves under the action of the first spiral wall and the centrifugal force, and the rotating wheel and the first spiral wall have relative movement, and the rotation of the centrifugal plate and the first spiral wall will produce a phase difference, so that the inner shaft and the inner shaft Phase difference, phase difference The scroll spring is compressed and twisted, and the reaction force of the scroll spring suppresses the generation of the phase difference. When the suppression force of the scroll spring and the force generated by the centrifugal force of the rotating wheel of the centrifugal plate are balanced, the inner shaft is synchronized with the cylinder shaft. Rotate. The greater the speed obtained by the cylinder shaft, the greater the centrifugal force of the second rotor, the greater the distance from the axis of the cylinder of the second rotor along the axis of the first spiral wall, and the greater the phase difference between the centrifugal plate and the cylinder axis. The scroll spring requires a large compression deformation to enable the inner shaft and the cylinder shaft to rotate under a large phase difference to achieve equilibrium; the compressed scroll spring releases energy when the cylinder shaft stops moving, and drives the inner shaft, a sliding slot and a first slider resetting the second rotating wheel;
当筒轴在第二齿轮带动下，第二转轮在随着第二支板上的第一螺旋壁旋转而旋转过程中，将会沿第一螺旋壁轨道相对运动，直到涡卷弹簧产生的力与离心力基本抵消，此时第二转轮径向位置一定，钻头的径向距离一定，可以钻相应直径的孔；当筒轴的转速提高，离心力增大，钻头继续随着第二转轮沿第一螺旋壁轨道相对运动，同时涡卷弹簧压缩，当压缩到与离心力增加产生的力相抵消后，钻头维持在一个新的径向位置且可以钻更大的孔。总之，钻头与旋转中心线的距离随着筒轴的速度变化而变化，不同的电机转速对应于钻头的可钻孔的直径。本发明第二转轮在运行中，受到离心力、涡卷弹簧产生经过离心板传导的力、还有钻头所钻孔物体施加的反作用力，三者达到平衡才能钻头才能维持一个恒定的径向位置，钻出稳定的孔，需要尽可能的保证涡卷弹簧产生的力与所钻物体施加的反
作用力处于同一大小量级，这样才能通过调节转速来维持不同孔径的孔钻孔过程中的稳定性，所以被钻物体材料硬度不能很硬。When the cylinder shaft is driven by the second gear, the second rotor will move relative to the first spiral wall track during the rotation with the rotation of the first spiral wall on the second support plate until the scroll spring generates The force and the centrifugal force are basically offset. At this time, the radial position of the second rotating wheel is fixed, the radial distance of the drill bit is fixed, and the hole of the corresponding diameter can be drilled; when the rotational speed of the cylindrical shaft is increased, the centrifugal force is increased, and the drill bit continues with the second rotating wheel. The first spiral wall track moves relative to each other while the scroll spring compresses, and when compressed to counteract the force generated by the increased centrifugal force, the bit remains at a new radial position and a larger hole can be drilled. In summary, the distance of the drill bit from the centerline of rotation varies with the speed of the shaft, and the different motor speeds correspond to the drillable diameter of the drill bit. In the operation, the second rotating wheel of the invention is subjected to centrifugal force, the force generated by the scroll spring to be transmitted through the centrifugal plate, and the reaction force exerted by the object drilled by the drill bit, and the balance is balanced before the drill bit can maintain a constant radial position. Drilling a stable hole, it is necessary to ensure as much as possible the force generated by the scroll spring and the opposite of the object being drilled
The force is on the same magnitude, so that the stability of the hole drilling process with different apertures can be maintained by adjusting the rotation speed, so the hardness of the material to be drilled cannot be very hard.

综上所述，如图2所示，本发明中第一支板、筒轴、第二齿轮、第二支板组成一个旋转整体，第一螺旋壁随着第二支板旋转，内轴、离心板固定在一起，内轴随着离心板围绕内轴轴线的旋转而旋转，内轴与筒轴之间具有涡卷弹簧，内轴与筒轴之间的转速或者相位差不同，涡卷弹簧将会被扭转压缩；当第一支板在筒轴带动下旋转，第二转轮将会在第一螺旋壁轨道中做离心螺旋运动，第二转轮会从第一螺旋壁的内始端向外终端运动，运动中通过第二转轮上的第二滑块与离心板的第一滑槽配合带动离心板围绕筒轴轴线旋转；之后离心板带动内轴旋转，因为离心板通过了转轮带动，转轮的运动在第一螺旋壁和离心力共同作用下运动，转轮与第一螺旋壁是具有相对运动的，离心板与第一螺旋壁的旋转将产生相位差，使得内轴与和筒轴之间产生相位差，相位差导致涡卷弹簧被压缩扭转，涡卷弹簧的反作用力抑制相位差的产生，当涡卷弹簧的抑制力、离心板受到的转轮离心力运动所产的力达到平衡时，内轴与筒轴同步旋转。筒轴获得的速度越大，第二转轮的离心力越大，第二转轮沿第一螺旋壁轨道运动中离筒轴的轴线距离越大，离心板相对与筒轴的相位差越大，涡卷弹簧就需要较大的压缩形变才能够使内轴与筒轴在较大的相位差下旋转达到平衡；被压缩的涡卷弹簧在筒轴停止运动时能量释放，通过带动内轴、第一滑槽、第一滑块对第二转轮进行复位；In summary, as shown in FIG. 2, in the present invention, the first support plate, the cylindrical shaft, the second gear, and the second support plate form a rotating whole body, and the first spiral wall rotates along with the second support plate, the inner shaft, The centrifugal plates are fixed together, the inner shaft rotates with the rotation of the centrifugal plate around the inner shaft axis, and a scroll spring is arranged between the inner shaft and the cylinder shaft, and the rotational speed or phase difference between the inner shaft and the cylinder shaft is different, and the spiral spring Will be torsionally compressed; when the first support plate rotates under the rotation of the cylinder shaft, the second rotation wheel will perform centrifugal spiral motion in the first spiral wall track, and the second rotation wheel will be from the inner beginning end of the first spiral wall The outer terminal moves, and the second slider on the second rotating wheel cooperates with the first sliding slot of the centrifugal plate to drive the centrifugal plate to rotate around the axis of the cylindrical shaft; then the centrifugal plate drives the inner shaft to rotate because the centrifugal plate passes the rotating wheel Driven, the movement of the runner moves under the action of the first spiral wall and the centrifugal force, and the runner and the first spiral wall have relative motion, and the rotation of the centrifugal plate and the first spiral wall will produce a phase difference, so that the inner shaft and the Phase difference between the cylinder shafts, phase difference guide The scroll spring is compressed and twisted, and the reaction force of the scroll spring suppresses the generation of the phase difference. When the suppression force of the scroll spring and the force generated by the centrifugal force of the rotating wheel of the centrifugal plate are balanced, the inner shaft is synchronized with the cylinder shaft. Rotate. The greater the speed obtained by the cylinder shaft, the greater the centrifugal force of the second rotor, the greater the distance from the axis of the cylinder of the second rotor along the axis of the first spiral wall, and the greater the phase difference between the centrifugal plate and the cylinder axis. The scroll spring requires a large compression deformation to enable the inner shaft and the cylinder shaft to rotate under a large phase difference to achieve equilibrium; the compressed scroll spring releases energy when the cylinder shaft stops moving, and drives the inner shaft, a sliding slot and a first slider resetting the second rotating wheel;
当筒轴在第二齿轮带动下，第二转轮在随着第二支板上的第一螺旋壁旋转而旋转过程中，将会沿第一螺旋壁轨道相对运动，直到涡卷弹簧产生的力与离心力基本抵消，此时第二转轮径向位置一定，钻头的径向距离一定，可以钻相应直径的孔；当筒轴的转速提高，离心力增大，钻头继续随着第二转轮沿第一螺旋壁轨道相对运动，同时涡卷弹簧压缩，当压缩到与离心力增加产生的力相抵消后，钻头维持在一个新的径向位置且可以钻更大的孔。总之，钻头与旋转中心线的距离
随着筒轴的速度变化而变化，不同的电机转速对应于钻头的可钻孔的直径。本发明第二转轮在运行中，受到离心力、涡卷弹簧产生经过离心板传导的力、还有钻头所钻孔物体施加的反作用力，三者达到平衡才能钻头才能维持一个恒定的径向位置，钻出稳定的孔，需要尽可能的保证涡卷弹簧产生的力与所钻物体施加的反作用力处于同一大小量级，这样才能通过调节转速来维持不同孔径的孔钻孔过程中的稳定性，所以被钻物体材料硬度不能很硬。When the cylinder shaft is driven by the second gear, the second rotor will move relative to the first spiral wall track during the rotation with the rotation of the first spiral wall on the second support plate until the scroll spring generates The force and the centrifugal force are basically offset. At this time, the radial position of the second rotating wheel is fixed, the radial distance of the drill bit is fixed, and the hole of the corresponding diameter can be drilled; when the rotational speed of the cylindrical shaft is increased, the centrifugal force is increased, and the drill bit continues with the second rotating wheel. The first spiral wall track moves relative to each other while the scroll spring compresses, and when compressed to counteract the force generated by the increased centrifugal force, the bit remains at a new radial position and a larger hole can be drilled. In short, the distance between the drill bit and the centerline of rotation
As the speed of the drum shaft changes, different motor speeds correspond to the drillable diameter of the drill bit. In the operation, the second rotating wheel of the invention is subjected to centrifugal force, the force generated by the scroll spring to be transmitted through the centrifugal plate, and the reaction force exerted by the object drilled by the drill bit, and the balance is balanced before the drill bit can maintain a constant radial position. Drilling a stable hole requires as much as possible to ensure that the force generated by the scroll spring is of the same magnitude as the reaction force applied by the object being drilled, so that the stability of the hole drilling process with different bore diameters can be maintained by adjusting the rotational speed. Therefore, the hardness of the material being drilled cannot be very hard.
具体实施方式如下：首先确定了钻孔的直径、钻孔的材料、然后调节电机转速达到一个合适的钻孔转速，之后打开电机，电机旋转带动钻头围绕筒轴轴线旋转，达到一个稳定的旋转径向位置后，开始打孔；打孔结束后，电机停转，在涡卷弹簧恢复后，内轴、第二转轮均恢复，等待下一次的打孔。
The specific embodiment is as follows: firstly determine the diameter of the drill hole, the material of the drill hole, and then adjust the motor speed to reach a suitable drilling speed, then turn on the motor, and the motor rotates to drive the drill bit to rotate around the axis of the cylinder shaft to achieve a stable rotation diameter. After the position is turned, the hole is started; after the hole is finished, the motor stops, and after the scroll spring is restored, the inner shaft and the second wheel are restored, waiting for the next punch.
