Clamp for processing lower frame of household appliance

Abstract

This utility model relates to the field of home appliance processing technology, specifically a fixture for processing the lower frame of a home appliance. It includes a base, with eight downward-pressing cylinders bolted to the bottom of the base. The piston ends of the downward-pressing cylinders penetrate the base, and their ends are rigidly connected to pressure blocks via bolts. The pressure blocks are M-shaped, with their pressure feet on both sides fitting into the interior of a contoured tooling plate. This utility model utilizes the self-locking effect of the curved surfaces of the M-shaped pressure blocks and the contoured tooling plate to achieve a gradient distribution of clamping force along the workpiece contour, avoiding plastic deformation of thin-walled parts caused by localized pressure concentration. Simultaneously, the composite support structure of the I-shaped base and the modular design of the mounting groove simultaneously improve the rigidity and changeover efficiency of the fixture system, ensuring consistent datum accuracy for processing different workpiece models.
