[0034] The specific usage and function of this embodiment are as follows:

[0035] In use, the operator first installs the positioning and clamping mechanism on the CNC shearing machine and debugs the drive system. Then, based on the thickness and material of the sheet metal to be processed, the operator adjusts the positioning and fixing mechanism 61. The operator replaces the appropriate spring 616, fixing block 617, and shim 6172 as required to ensure that the sheet metal is processed under the most suitable conditions. After all components are adjusted, the operator adjusts the parameters required for sheet metal processing through the control panel 5. Then, the operator transports the sheet metal to the worktable 62, where it is held in place by the stop block 646. The servo motor 642 drives the lead screw 643 to rotate, which in turn drives the slider 644 to move longitudinally. The slider 644 drives the clamping block 645 to move longitudinally, so that it works with the stop block 646 to clamp the sheet metal and prevent it from moving during transportation.

[0036] Then, the drive motor 633 starts, driving the transmission screw 634 to rotate, which in turn drives the transmission slider 636 to slide. The T-shaped block on the transmission slider 636 drives the clamping mechanism 64 to slide, realizing material feeding. Further, when the sheet material is transported to the designated processing position, the hydraulic cylinder 611 drives the hydraulic push rod 612 to move, which in turn drives the connecting plate 613 and the threaded connecting rod 614 fixedly installed under the connecting plate 613 to move longitudinally. Then, the threaded connecting rod 614 drives the fixing block 617 to move longitudinally, and then, with the help of the shim 6172, fixes the sheet material to prevent it from moving or deforming due to force during processing. Further, after the shearing is completed, the hydraulic push rod 612 retracts, which drives the fixing block 617 away from the sheet material, and then the feeding sheet material is fixed repeatedly.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
