[0022] A telescopic sleeve 401 is installed at the front end of the electric cylinder 4. The front end of the telescopic sleeve 401 is rotatably connected to the spline shaft 402 through a bearing. The telescopic sleeve 401 is used to telescopically adjust the position of the spline shaft 402. The electric cylinder 4 adjusts the positions of the first clutch gear 403 and the second clutch gear 404 so that the first clutch gear 403 and the second clutch gear 404 are respectively meshed and connected with the transmission gear 501. The first clutch gear 403 drives the spline shaft 402 and the threaded rod 304 to rotate. By adjusting the electric cylinder 4 at different positions, the first clutch gear 403 and the second clutch gear 404 at four different positions are respectively meshed with the transmission gear 501.

[0024] In order to solve the technical problem that the auxiliary positioning device structure has general position stability and is not conducive to long-term work in the prior art, please refer to Figure 1 - Figure 2 , providing the following technical solutions:

[0025] A connecting frame 102 is installed at the front end of the support seat 1, and fastening blocks 103 are installed at the upper and lower ends of the connecting frame 102. A sliding positioning rod 303 is installed inside the fastening block 103, and the sliding positioning rod 303 is fixedly connected to the fastening block 103. A moving seat 302 is installed at the rear end of the pushing seat 3. The sliding positioning rod 303 penetrates the moving seat 302 and is slidably connected to the moving seat 302. The position stability of the pushing seat 3 is maintained by the sliding positioning rod 303, so that the pushing seat 3 remains horizontal during the movement.

The threaded rod 304 extends to the inside of the moving seat 302 and is threadedly connected to the moving seat 302.

[0027] Specifically, the threaded rod 304 rotates and the moving seat 302 moves. The anti-slip pad 301 increases the friction force, so that the position stability of the pushing seat 3 is improved during the pushing process. The sliding positioning rod 303 maintains the position stability of the pushing seat 3, so that the pushing seat 3 remains horizontal during the movement.

[0028] Working principle: The driving gear 201 is driven to rotate by the servo motor 2, and the driving gear 201 drives the first clutch gear 403 and the second clutch gear 404 to rotate, so that the threaded rod 304 rotates and the moving seat 302 moves. The friction force is increased by the anti-slip pad 301, so that the position stability of the pushing seat 3 is improved during the pushing process. The position stability of the pushing seat 3 is maintained by the sliding positioning rod 303, so that the pushing seat 3 remains horizontal during the moving process, so that according to the bending angle and the bevel position of the actual parts, adjustment and assistance are performed to adapt to the bending work. By adjusting the electric cylinder 4 at different positions, the first clutch gear 403 and the second clutch gear 404 at four different positions are respectively meshed with the transmission gear 501. When the second clutch gear 404 is meshed with the transmission gear 501, the pushing seat 3 at the corresponding position is stationary, and when the first clutch gear 403 is subjected to force, the pushing seat 3 at the corresponding position can be displaced, so that the pushing seat 3 at different positions can be moved, and the adjustable effect is good, which is convenient for adapting to parts of different types and sizes, and has good adaptability and strong practicality.
