The driving device 601 drives the guide plate 602 to move, and then the worker can place multiple special-shaped parts between multiple limit plates 603 on the top of the guide plate 602. When the driving device 601 drives the limit plates 603 to reset, the special-shaped parts between the limit plates 603 will be exactly level with the internal clamping end of the clamping mechanism 2, thereby facilitating the clamping mechanism 2 to clamp them.

[0029] Specifically, Figure 4 As shown, in order to accommodate the limit plate 603, the interior of the groove 7 is connected to the limit plate 603 via the telescopic rod 2 701. The limit plate 603 will be retracted into the interior of the groove 7 under the action of the telescopic rod 2 701, thereby facilitating other processing devices to process the side of the special-shaped part.

[0030] Further, the clamping mechanism 2 includes a telescopic rod 201, a connecting plate 202, a clamping block 203 and a clamping plate 204. The clamping plate 204 is installed at one end of the top of the workstation 1, and the telescopic rod 201 is installed at one end of the top of the workstation 1 away from the clamping plate 204. The connecting plate 202 is installed at the telescopic end of the telescopic rod 201, and multiple groups of clamping blocks 203 are installed at one end of the connecting plate 202 away from the telescopic rod 201.

[0031] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, in order to achieve clamping of multiple special-shaped parts, the telescopic rod 201 works, and the telescopic end of the telescopic rod 201 drives the clamping block 203 to move through the connecting plate 202.

[0033] Specifically, Figure 1 and Figure 2 As shown, in order to improve the clamping effect of the clamping mechanism 2 on the special-shaped part, the transmission rod 301 can be rotated to prompt the moving block 302 to drive the clamping block 203 to move, and then the special-shaped part can be clamped for the second time, thereby improving the clamping effect of the clamping mechanism 2 on the special-shaped part.

[0034] Further, a guide rod 8 is installed at one end of the clamping block 203 close to the bottom of the transmission rod 301;

[0035] Specifically, Figure 2 and Figure 3 As shown, in order to keep the clamping block 203 horizontal during the movement, when the clamping block 203 moves, one end of the guide rod 8 moves inside the transmission rod 301, so that the clamping block 203 can be kept horizontal during the movement.

When the positioning pin 5 is taken out from the through groove 303 and the boss 4, the clamping block 203 can be replaced to clamp other special-shaped workpieces.

[0038] Working principle: workers place multiple special-shaped parts between multiple limit plates 603 on the top of the guide plate 602. When the driving device 601 drives the limit plates 603 to reset, the special-shaped parts between the limit plates 603 will be exactly level with the clamping ends of the clamping block 203 and the clamping plate 204. Then, the clamping block 203 is driven to move through the connecting plate 202 by the telescopic end of the telescopic rod 201. The clamping force generated between the clamping block 203 and the clamping plate 204 can clamp the multiple special-shaped parts therebetween.
