Under the pull of the spring 15, the connecting plate 12 moves back, so that the positioning plate 19 returns to its original position, thereby leaving space for the automobile chassis and facilitating the placement of the automobile chassis. Through the above process, the automobile chassis can be automatically centered and fixed during the rotation of the automobile chassis, solving the problem that the placed automobile chassis is centered by the guide beams on both sides, but the automobile chassis contacts the guide beams, which is prone to bumps, thereby causing damage to the surface of the automobile chassis and affecting the appearance quality.

[0024] When the vehicle chassis is placed on the chassis 1, the motor 2 is started to drive the chassis 1 and the vehicle chassis to rotate. During this process, the transmission rod 7 moves along the ring 4. When the transmission rod 7 slides out of the groove 5 on the ring 4, one end of the transmission rod 7 is lifted, and the transmission rod 7 drives the transmission shaft 8 to rotate along the rotating seat 9. The transmission shaft 8 drives the first connecting rod 10 to rotate. The first connecting rod 10 pushes the connecting plate 12 toward the middle of the chassis 1 through the second connecting rod 11. The connecting plate 12 drives the first guide rod 14 to move toward the middle along the support 13 and stretches the spring 15. The connecting plate 12 pushes the positioning plate 19 toward the middle of the chassis 1 through the threaded rod 17, thereby clamping the vehicle chassis and centering it. When returning to its original position, the transmission rod 7 moves along the ring 4 and falls back into the groove 5. Under the pull of the spring 15, the connecting plate 12 moves back, so that the positioning plate 19 returns to its original position, thereby leaving space for the vehicle chassis and facilitating the placement of the vehicle chassis.
