[0002] After my search, the prior art discloses a pneumatic tooling fixture for non-ferrous metal rolled extrusions (application number 202120684669.2), which includes a mounting seat and a pneumatic clamping assembly. The workpiece to be processed is placed on the mounting seat. The pneumatic clamping assembly includes a cylinder and a clamping block. The cylinder is fixedly connected to the clamping block, and the cylinder can drive the clamping block to move toward the direction of the workpiece to be processed on the mounting seat. The side of the clamping block close to the mounting seat is pressed against the workpiece to be processed.

[0003] The pneumatic tooling fixture for non-ferrous metal rolled extrusions disclosed in the above-cited document limits the metal plate by means of mounting grooves, but the size of the mounting grooves is fixed and the scope of application is limited. The metal plate is pressed by means of buffer shock-absorbing blocks, but when the metal plate is stretched during rolling, sliding friction between the metal plate and the shock-absorbing blocks may cause scratches and other damages.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0011] As a preferred embodiment of the utility model, through holes are evenly spaced between the top and bottom of the mounting plate and between the two mounting grooves. The clamping assembly includes a cylinder and a fixed plate. The cylinders are fixedly connected to the top of the base plate at positions corresponding to the through holes, and the piston rod at the top of the cylinder penetrates the inner wall of the through hole in a sliding connection. The middle position of the bottom of the fixed plate is fixedly connected to the top of the piston rod.

[0012] As a preferred embodiment of the utility model, sliding holes are provided at both ends of the top and bottom of the fixing plate, and the clamping assembly further comprises two sliding rods, which respectively penetrate the inner walls of the two sliding holes to be slidably connected.
