[0021] The bottom surface of the operating table 2 is provided with a circle of slide grooves 18, which are provided along the edge of the movable groove 9. The bottom end of the connecting rod 5 is fixedly mounted with a fitting plate 10, which fits the bottom surface of the operating table 2. A slider 11 is fixedly mounted on one end of the fitting plate 10, which is embedded in the slide groove 18. An interlocking rod 12 is fixedly mounted on the bottom of the fitting plate 10, and a guide block 13 is fixedly mounted on the outer wall of the interlocking rod 12. The fitting plate 10 is made of a magnet and is adsorbed on the bottom outer wall of the operating table 2. A fixed ring 19 is fixedly mounted on the output end of the motor 8, and a movable rod 16 is installed through the fixed ring 19. A collar 15 is fixedly mounted on the end of the movable rod 16, and a bearing is fixedly mounted on the inner wall of the collar 15. A center block 14 is fixedly mounted on the inner wall of the bearing axis. A matching hole is provided through the outer wall of the center block 14, and the interlocking rod 12 and the guide block 13 are fitted into the matching hole of the center block 14. A spring 17 is sleeved on the outer wall of the movable rod 16 , and the spring 17 is installed between the collar 15 and the fixed ring 19 .

[0022] Below the fixed ring 19 is provided with a lifting ring 6, which is fixedly installed on the output end of the air cylinder 7. The inner wall of the ring core of the lifting ring 6 is fixedly installed with a fixed rod 20. The bottom outer wall of the fixed ring 19 is connected with the fixed rod 20 through a bearing.

[0023] Embodiment: The base 1 is installed on the trimming station of the battery shell. The inside of the mold 3 has a pressed battery box blank. The motor 8 is started to drive the fixed ring 19 to rotate, the fixed ring 19 drives the movable rod 16 to rotate, the movable rod 16 drives the sleeve ring 15, the sleeve ring 15 drives the center block 14, the center block 14 drives the embedded rod 12, the embedded rod 12 drives the fitting plate 10, the fitting plate 10 drives the connecting rod 5, the connecting rod 5 drives the inductor 4, the connecting rod 5 moves in the area between the bottom edge of the mold 3 and the inner wall of the movable groove 9, and drives the inductor 4 to scan to check whether the top edge of the battery box completely exceeds the mold 3. During the rotation process, since the movement track of the connecting rod 5 is fixed, the movable rod 16 is telescopic in the fixed ring 19 to match the position change of the connecting rod 5. The spring 17 provides the force for rebounding and resetting and the resistance when the length is contracted.

[0024] The fitting plate 10 moves with the connecting rod 5. When the corner is encountered, the fitting plate 10 is driven to turn by the sliding block 11 embedded in the sliding groove 18. When the fitting plate 10 rotates, the embedded rod 12 at the bottom drives the center block 14 to rotate with the guide block 13, which is used for turning the fitting plate 10. The fitting plate 10 smoothly turns, so that the sensing end of the inductor 4 is always directed to the mold 3. The sensing mode of the inductor 4 is microwave sensing. The microwave is emitted to the outer wall of the battery shell, and then the reflected signal is received to determine whether there is a gap in the top edge of the battery shell. If there is a gap, the microwave emitted by the inductor 4 cannot be recovered in time.

[0025] If it is detected that there is no gap in the top edge of the battery box, the air cylinder 7 is started to drive the lifting ring 6 to rise. The fixed ring 19 is connected with the fixed rod 20 in the lifting ring 6 through a bearing. Therefore, when the lifting ring 6 rises, the fixed ring 19 can be driven by the fixed rod 20 without affecting the rotation of the fixed ring 19. The fixed ring 19 is driven to rise. The fixed ring 19 drives the motor 8, and the motor 8 drives the mold 3 to rise. When the fixed ring 19 rises, the fixed ring 19 drives the sleeve ring 15, the sleeve ring 15 drives the center block 14, and the center block 14 rises with the embedded rod 12 and the guide block 13 as the guide. When rising, the motor 8 drives the sleeve ring 15 to rotate to the side away from the fixed rod 20 to prevent the fixed rod 20 from interfering with the bottom of the embedded rod 12. In this way, the mold 3 is driven to rise away from the table top of the operation table 2. The air cylinder 7 drives the mold 3 to rise to the station for trimming the top edge of the battery box.

[0026] If the inductor 4 detects a gap in the battery box after one rotation, the air cylinder 7 will not be started, and the operator will take away the non-compliant battery box.

[0027] It should be noted that the parts not involved in the present application are the same as the prior art or can be realized by using the prior art; various drives in the present application can be realized by cooperating corresponding power structures such as air cylinders, oil cylinders, electric cylinders and motors with connecting rods and guide rods, and are not limited to the description in the specification and the structure in the drawings.

[0028] The above-described embodiments only express several implementation manners of the present application, the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the utility model patent. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
