[0024] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5The cam 308 is fixed on the top of the workbench 1, and the cam 308 is fixed on the top of the workbench 1. The cam 303 is provided with a lock hole 306 on the top of the locking plate 301, and the lock hole 306 is provided with a lock hole 306 on the bottom of the locking plate 301. The cam 303 is provided with a lock hole 306 on the top of the locking plate 301, and the lock hole 306 is provided with a lock hole 306 on the bottom of the locking plate 301.

[0025] When installing the clamping plate 5 of other specifications, the connecting sleeve 308 is set on the outside of the fixed column 301, and the sliding support leg 309 enters the inner side of the hook slot 3014 and slides. At the same time, due to the setting of the slope surface 3082, when the connecting sleeve 308 contacts the locking column 305, it will enter the receiving groove 3011, and the column return spring 303 will be compressed until it slides to the end of the hook slot 3014 along the sliding support leg 309. At this time, the locking column 305 enters the inner side of the column hook slot 3081, and then the connecting sleeve 308 is rotated, and the connecting sleeve 308 is fixed to the fixed column 30 1 slides laterally, the connecting sleeve 308 contacts the locking column 305 and compresses the return spring 307. Then, the connecting sleeve 308 is rotated, so that the connecting sleeve 308 automatically retreats by the elastic force of the return spring 307, so that the locking column 305 is clamped into the end of the column hook groove 3081. The spring coefficient of the return spring 307 is greater than the clamping force that can be generated by the clamping plate 5, thereby preventing the connecting sleeve 308 from being dislocated, thereby achieving the effect of quickly replacing and installing the clamping plate 5, and improving the production and processing efficiency of automobile parts of different specifications.

[0026] Reference Figure 1 and Figure 2 , the vertical connecting plate 4 is arranged at the top of the workbench 1, and the vertical connecting plate 4 is provided with two, the clamping mechanism 2 includes a driving motor 201, and the driving end of the driving motor 201 is fixedly provided with a driving screw 202, and the outer side of the driving screw 202 is symmetrically meshed with a moving block 203. The top of the workbench 1 is provided with a sliding groove, and the moving block 203 is slidingly arranged on the inner side of the sliding groove. The moving block 203 is detachably arranged at the bottom end of the vertical connecting plate 4,, a protective telescopic cover 101 is fixedly provided on one side of the moving block 203, and the protective telescopic cover 101 is fixedly arranged on the inner side of the sliding groove. The outer side of the driving motor 201 is fixedly provided with a motor bracket 204, and the motor bracket 204 is detachably arranged at the top of the workbench 1, and the driving screw 202 is rotatably arranged at the bottom end of the workbench 1.

[0027] When clamping auto parts, the drive motor 201 in the clamping mechanism 2 is started, and the drive motor 201 drives the driving screw 202 to rotate. The rotation of the driving screw 202 drives the moving blocks 203 to move closer to or away from each other, so that the vertical connecting plate 4 drives the quick-assembly component 3 and the clamping plate 5 to move closer to or away from each other. The clamping plates 5 move closer to each other to clamp the auto parts, thereby achieving the effect of fixing the auto parts.

[0028] The working principle of the present invention is as follows: when clamping an automobile part, the driving motor 201 in the clamping mechanism 2 is started, and the driving motor 201 drives the driving screw 202 to rotate. The rotation of the driving screw 202 drives the moving blocks 203 to move closer to or away from each other, thereby causing the vertical connecting plate 4 to drive the quick-assembly component 3 and the clamping plate 5 to move closer to or away from each other. The clamping plates 5 move closer to each other to clamp the automobile part, thereby achieving the effect of fixing the automobile part.

[0029] When installing the clamping plate 5 of other specifications, the connecting sleeve 308 is set on the outside of the fixed column 301, and the sliding support leg 309 enters the inner side of the hook slot 3014 and slides. At the same time, due to the setting of the slope surface 3082, when the connecting sleeve 308 contacts the locking column 305, it will enter the receiving groove 3011, and the column return spring 303 will be compressed until it slides to the end of the hook slot 3014 along the sliding support leg 309. At this time, the locking column 305 enters the inner side of the column hook slot 3081, and then the connecting sleeve 308 is rotated, and the connecting sleeve 308 is fixed to the fixed column 30 1 slides laterally, the connecting sleeve 308 contacts the locking column 305 and compresses the return spring 307. Then, the connecting sleeve 308 is rotated, so that the connecting sleeve 308 automatically retreats by the elastic force of the return spring 307, so that the locking column 305 is clamped into the end of the column hook groove 3081. The spring coefficient of the return spring 307 is greater than the clamping force that can be generated by the clamping plate 5, thereby preventing the connecting sleeve 308 from being dislocated, thereby achieving the effect of quickly replacing and installing the clamping plate 5, and improving the production and processing efficiency of automobile parts of different specifications.
