Abstract

This utility model relates to the field of metal shell processing, and more particularly to a fixture for metal shell processing. A pair of clamping blocks are symmetrically mounted on the upper part of the frame via a mounting plate. One end of each clamping block is connected to a lead screw clamping mechanism, and extension blocks are mounted on both sides of each clamping block. Guide plates are provided on the inner walls of the extension blocks, extending into the clamping blocks and correspondingly limiting the connection with the guide blocks. The guide blocks are installed inside the clamping blocks via a lead screw. In this utility model, by adjusting the adjusting head on the upper part of the clamping blocks, the guide blocks inside the clamping blocks are driven to squeeze and push the extension block assembly, thereby increasing the overall clamping area of the fixture on the workpiece. This results in a more uniform and distributed clamping force, effectively preventing damage to the workpiece surface and improving processing efficiency.
