This moving mechanism includes a mounting plate, with two ends of the mounting plate connected to moving screws via bearings. One end of the moving screw passes through the mounting plate and is fixedly connected to the output end of a moving motor. A moving threaded sleeve is fitted onto the surface of the moving screw inside the mounting plate, and a clamping mechanism is fixedly installed on the top of the moving threaded sleeve. This clamping device for automotive pin production, by setting up the moving mechanism, allows personnel to start the moving motor to drive the moving screw to rotate according to the length of the automotive pin during clamping and installation. This controls the movement of the moving threaded sleeve mounted on the surface of the moving screw, facilitating the adjustment of the clamping mechanism's position according to the length of the automotive pin and avoiding frequent changes of the clamping device when processing automotive pins of different lengths.

[0003] The existing technical solutions mentioned above have the following drawbacks: the curvature of the support plate is fixed. When clamping other types of drive shafts, the curvature of the support plate cannot be adapted to other types of drive shafts, which means that the support plate can only clamp fixed types of drive shafts. This limits the use of the clamping device and reduces the effectiveness of the clamping device. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a clamping device for drive shaft production, which has the advantage of good adaptability. It solves the problem that the curvature of the support plate is fixed, and when clamping other types of drive shafts, the curvature of the support plate cannot be adapted to other types of drive shafts, resulting in the support plate only being able to clamp fixed types of drive shafts, which limits the use of the clamping device and reduces its effectiveness.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for drive shaft production, comprising a base, a motor fixedly connected to the right side of the base, the output end of the motor penetrating into the interior of the base, a screw fixedly connected to the output end of the motor, a moving block threadedly connected to the surface of the screw, a clamping seat fixedly connected to the top of the moving block, an electric cylinder fixedly connected to the front and rear sides of the top of the clamping seat, a pressing seat fixedly connected to the output end of the electric cylinder, a support seat fixedly connected to the left side of the top of the base, clamping plates provided on the surfaces of the clamping seat, the pressing seat, and the support seat, two slots provided on the surface of the clamps, and a locking mechanism provided inside the slots.

[0006] In a preferred embodiment of this utility model, the locking mechanism includes a locking block that is locked inside a slot. The side of the locking block away from the slot extends into the interior of the clamping seat, the pressing seat, and the support seat, respectively. The side of the locking block away from the slot is movably connected to the interior of the clamping seat, the pressing seat, and the support seat, respectively. An inclined block is fixedly connected to the inner side of the locking block. A control plate is provided on the inner side of the inclined block. An electric push rod is fixedly connected to the surface of the control plate. The surface of the electric push rod is fixedly connected to the inner wall of the clamping seat, the pressing seat, and the support seat.

[0007] As a preferred embodiment of this invention, a spring sheet is fixedly connected to the surface of the card block, and the surface of the spring sheet is fixedly connected to the inner wall of the clamping seat, the pressing seat, and the supporting seat.

[0008] As a preferred embodiment of this utility model, stabilizing rods are provided on both sides inside the control board, and the surfaces of the stabilizing rods are fixedly connected to the inner walls of the clamping seat, the pressing seat, and the support seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model allows for the removal of the clamping plate from the surfaces of the clamping seat, pressure seat, and support seat. When the clamping plate needs to be removed, an electric push rod is activated, causing the control plate to move. The control plate loses its support force on the inclined block, and as the inclined block loosens, the locking block also loosens, losing its locking effect with the slot. The clamping plate then loses its fixing effect with the clamping seat, pressure seat, and support seat, allowing the clamping plate to be removed. Then, a clamping plate with a suitable arc-shaped groove is selected based on the required drive shaft and fixed using a locking mechanism. This allows the clamping seat and pressure seat to fix different models of drive shafts, providing good adaptability. The clamping fixing plate is replaceable, and the arc-shaped groove inside the clamping fixing plate changes accordingly, allowing the clamping fixing plate to adapt to other models of drive shafts, thus improving the effectiveness of the clamping device.

[0014] 2. By setting up a snap-fit ​​mechanism, this utility model can replace the clamping plate, avoiding the situation where the clamping plate is fixed and the clamping device can only clamp one type of drive shaft, thus improving the diversity of fixed drive shafts.

An electric push rod 114 is fixedly connected to the surface of the control plate 113. The surface of the electric push rod 114 is fixedly connected to the inner wall of the clamping seat 5, the pressing seat 7, and the support seat 8.

[0022] As a technical optimization of this utility model, by setting the snap-fit ​​mechanism 11, the clamping plate 9 can be replaced, avoiding the clamping plate 9 being fixed, which would cause the clamping device to only clamp one type of drive shaft, thus improving the diversity of fixed drive shafts.

[0023] refer to Figure 3 A spring piece 12 is fixedly connected to the surface of the card block 111, and the surface of the spring piece 12 is fixedly connected to the inner wall of the clamping seat 5, the pressing seat 7 and the support seat 8.

[0024] As a technical optimization of this utility model, by setting the spring piece 12, the locking block 111 can be pulled to automatically reset and move, avoiding the locking block 111 from being unable to rotate automatically after losing support, thus improving the ease of use of the locking block 111.

[0025] refer to Figure 3 The control panel 113 has two sides with stabilizing rods 13. The surfaces of the stabilizing rods 13 are fixedly connected to the inner walls of the clamping seat 5, the pressing seat 7 and the support seat 8.

[0026] As a technical optimization of this utility model, by setting a stabilizing rod 13, the control plate 113 can be stabilized during sliding, avoiding shaking of the control plate 113 during sliding and moving, which would cause the control plate 113 to loosen, thus improving the sliding stability of the control plate 113.

[0027] refer to Figure 3 A sliding sleeve 14 is fitted onto the surface of the stabilizer bar 13, and the surface of the sliding sleeve 14 is fixedly connected to the surface of the control plate 113.

[0028] As a technical optimization of this utility model, by setting the sliding sleeve 14, the control plate 113 can be stabilized by secondary sliding, avoiding the shaking of the control plate 113 during sliding and moving, which would cause the control plate 113 to loosen, and improving the sliding stability of the control plate 113.

[0029] refer to Figure 1 The base 1 has a limiting groove 15 on the front and rear sides of the top. The limiting groove 15 is provided with a limiting slide 16 inside. The surface of the limiting slide 16 is fixedly connected to the bottom of the clamping seat 5.

[0030] As a technical optimization of this utility model, by setting the limiting slide groove 15 and the limiting slide bar 16, the clamping seat 5 can be stabilized during sliding, avoiding shaking of the clamping seat 5 during sliding and movement, which would cause the clamping seat 5 to loosen, and improving the sliding stability of the clamping seat 5.

[0031] refer to Figure 1 A stabilizing sleeve 17 is fitted on the left side of the screw 3 surface, and the left side of the stabilizing sleeve 17 is fixedly connected to the inner wall of the base 1.

[0032] As a technical optimization of this utility model, by setting the stabilizing sleeve 17, the screw 3 can be stabilized, avoiding the phenomenon of skewness during the rotation of the screw 3, and improving the stability of the screw 3 in use.

[0033] The working principle and usage process of this utility model are as follows: When it is necessary to remove the clamping plate 9 from the surface of the clamping seat 5, the lower pressure seat 7 and the support seat 8, the electric push rod 114 is activated. The electric push rod 114 drives the control plate 113 to move. The control plate 113 loses its supporting force on the inclined block 112. After the inclined block 112 is loosened, the locking block 111 is also loosened. The locking block 111 loses its locking effect with the locking groove 10. The clamping plate 9 loses its fixing effect with the clamping seat 5, the lower pressure seat 7 and the support seat 8. At this time, the clamping plate 9 can be removed. Then, according to the required drive shaft, a clamping plate 9 with a suitable arc groove is selected and fixed by the locking mechanism 11. In this way, the clamping seat 5 and the lower pressure seat 7 can fix different models of drive shafts.

[0034] In summary, this clamping device for drive shaft production, through the coordinated use of base 1, motor 2, screw 3, moving block 4, clamping seat 5, electric cylinder 6, pressing seat 7, support seat 8, clamping plate 9, slot 10, and clamping mechanism 11, solves the problem that the curvature of the support plate is fixed, and when clamping other types of drive shafts, the curvature of the support plate cannot be adapted to other types of drive shafts, resulting in the support plate only being able to clamp a fixed type of drive shaft, which limits the use of the clamping device and reduces its effectiveness.
