本实施例提供了一种卷制设备，用于将如图1所示的待加工件4卷制形成如图2所示的螺旋转轴，该螺旋转轴的螺旋结构44为经过卷制设备卷制而成的，该卷制设备还可以用于将丝状结构卷制成螺旋结构，以提高螺旋结构的精度。This embodiment provides a rolling device for rolling the workpiece 4 shown in FIG. 1 to form a spiral shaft as shown in FIG. 2. The spiral structure 44 of the spiral shaft is rolled by the rolling device As a result, the rolling equipment can also be used to roll the filament structure into a spiral structure to improve the accuracy of the spiral structure.
如图1所示，本实施例提供的待加工件4包括依次连接的衔接部42、卷制段41和固定段43。衔接部42与卷制段41呈角度设置，如可以呈45°夹角，当然，还可以为其他角度。如图2所示，本实施例提供的卷制设备可以将卷制段41卷制为螺旋结构44。As shown in FIG. 1, the workpiece 4 provided in this embodiment includes a connecting portion 42, a rolling section 41 and a fixing section 43 that are connected in sequence. The connecting portion 42 and the rolling section 41 are arranged at an angle, such as an angle of 45°, and of course, other angles are also possible. As shown in FIG. 2, the rolling device provided in this embodiment can roll the rolling section 41 into a spiral structure 44.
如图3所示，本实施例提供的卷制设备包括驱动件71、中心棒72、调节刀具74和限位组件73。驱动件71包括旋转轴711，旋转轴711能够绕其自身轴线旋转，驱动件71可以为电机，电机驱动旋转轴711旋转。中心棒72的一端设置于旋转轴711上并与旋转轴711同轴设置，待加工件4的固定段43可拆卸地连接于旋转轴711，待加工件4与中心棒72呈预设夹角。可以理解的是，待加工件4的卷制段41与中心棒72的预设夹角的大小决定了螺旋结构44的螺距的大小，预设夹角越大螺距越小，预设夹角越小，螺距则越大。通过控制待加工件4与中心棒72夹角即可得到预设的螺距，这使得螺旋结构44的螺距易于控制，达到了提高螺旋结构44的螺距精度的目的。As shown in FIG. 3, the rolling equipment provided in this embodiment includes a driving member 71, a center rod 72, an adjusting knife 74 and a limiting component 73. The driving member 71 includes a rotating shaft 711 that can rotate around its own axis. The driving member 71 may be a motor, and the motor drives the rotating shaft 711 to rotate. One end of the central rod 72 is arranged on the rotating shaft 711 and coaxially arranged with the rotating shaft 711, the fixed section 43 of the workpiece 4 to be processed is detachably connected to the rotating shaft 711, and the workpiece 4 to be processed and the central rod 72 form a preset angle . It is understandable that the preset included angle between the coiled section 41 of the workpiece 4 and the center rod 72 determines the pitch of the spiral structure 44. The larger the preset included angle, the smaller the pitch, the greater the preset included angle. The smaller the pitch, the larger the pitch. The preset pitch can be obtained by controlling the angle between the workpiece 4 to be processed and the center rod 72, which makes the pitch of the spiral structure 44 easy to control, and achieves the purpose of improving the pitch accuracy of the spiral structure 44.
待加工件4的衔接部42插设于限位组件73，在卷制过程中，衔接部42可以在限位组件73内平移，限位组件73可以限制衔接部42发生大幅度摆动，进而提高螺旋结构44的精度。The connecting portion 42 of the workpiece 4 to be processed is inserted into the limiting component 73. During the rolling process, the connecting portion 42 can be translated within the limiting component 73, and the limiting component 73 can restrict the connecting portion 42 from swinging greatly, thereby improving The accuracy of the spiral structure 44.
待加工件4的固定段43连接在旋转轴711上，并随旋转轴711旋转，待加工件4的衔接部42插设于限位组件73内，因此待加工件4只有一端能够旋转。又由于待加工件4与中心棒72呈预设夹角，因此，随着旋转轴711的旋转，卷制段41从靠近旋转轴711的一端向远离旋转轴711的一端逐渐螺旋缠绕在中心棒72上。The fixed section 43 of the workpiece 4 to be processed is connected to the rotating shaft 711 and rotates with the rotating shaft 711. The connecting portion 42 of the workpiece 4 to be processed is inserted into the limit assembly 73, so that only one end of the workpiece 4 to be processed can rotate. Also, because the workpiece 4 to be processed and the central rod 72 have a preset included angle, as the rotating shaft 711 rotates, the winding section 41 is gradually spirally wound around the central rod from an end close to the rotating shaft 711 to an end far away from the rotating shaft 711 72 on.
调节刀具74设置于中心棒72的下侧，调节刀具74能够将待加工件4的与旋转轴711连接的根部抵接于中心棒72。可以理解的是，待加工件4的根部为待加工件4靠近旋转轴711的轴端的一部分，该部分具有一定的长度。The adjusting tool 74 is provided on the lower side of the center rod 72, and the adjusting tool 74 can abut the root portion of the workpiece 4 connected to the rotating shaft 711 to the center rod 72. It can be understood that the root of the workpiece 4 to be processed is a part of the shaft end of the workpiece 4 close to the rotating shaft 711, and this part has a certain length.
由于衔接部42可以在限位组件73内平移，这就导致了衔接部42能够在限位组件73内有小距离的上下方向的运动，进而导致了待加工件4的根部不能按照要求快速缠绕在中心棒72上。调节刀具74能够抵接于待加工件4的根部， 从而使得待加工件4在与调节刀具74抵接的位置发生弯曲，并缠绕在中心棒72上，进一步提高螺旋结构44的精度。Since the connecting portion 42 can translate in the limiting component 73, this results in the connecting portion 42 being able to move up and down within a small distance in the limiting component 73, which in turn causes the root of the workpiece 4 to be processed cannot be quickly wound as required. On the center rod 72. The adjusting tool 74 can abut against the root of the workpiece 4 to be processed, so that the workpiece 4 to be processed bends at the position where it abuts the adjusting tool 74 and is wound on the central rod 72 to further improve the accuracy of the spiral structure 44.
卷制段41与中心棒72呈预设夹角，因此，只需要卷制段41的一端和中心棒72旋转即可以实现卷制段41的卷制，旋转轴711不必沿水平方向运动，即不必设置驱动旋转轴711水平移动的驱动结构，使得卷制设备的结构简单。The winding section 41 and the central rod 72 are at a preset angle. Therefore, only one end of the winding section 41 and the central rod 72 need to be rotated to realize the winding of the winding section 41, and the rotating shaft 711 does not have to move in the horizontal direction, that is, It is not necessary to provide a driving structure for driving the rotating shaft 711 to move horizontally, so that the structure of the rolling device is simple.
调节刀具74能够水平移动，以调节调节刀具74与旋转轴711的轴端的间距。当螺旋结构44的螺距较大时，可以增大调节刀具74与旋转轴711的轴端的间距；反之，亦然。The adjusting tool 74 can move horizontally to adjust the distance between the adjusting tool 74 and the shaft end of the rotating shaft 711. When the pitch of the spiral structure 44 is relatively large, the distance between the adjusting tool 74 and the shaft end of the rotating shaft 711 can be increased; and vice versa.
在一实施例中，调节刀具74包括调节连接臂741和调节板742，调节连接臂741连接于调节板742，待加工件4的根部能够抵接于调节板742。In an embodiment, the adjusting tool 74 includes an adjusting connecting arm 741 and an adjusting plate 742.

The center rod 72 is connected to the first half shaft 7111. One end of the workpiece 4 can be fixed to the first half shaft. Between 7111 and the second half shaft 7112. The connection of the first half shaft 7111 and the second half shaft 7112 can fix the workpiece 4 to be processed; after the first half shaft 7111 and the second half shaft 7112 are separated, the workpiece 4 to be processed can be removed.

Optionally, the depth of the accommodating groove is slightly less than or equal to the thickness of the workpiece 4 to be processed, so as to prevent the workpiece 4 from shaking in the vertical direction.
