AI Technical Summary

Technical Problem

Existing fixture technology suffers from problems such as dispersed processes, low clamping efficiency, insufficient fixture rigidity, easy bending and deformation of workpieces, chatter, and unstable machining accuracy when machining irregularly shaped workpieces.

Method used

A multi-process milling fixture was designed, which integrates a center pin, a floating wedge compensation mechanism, a hook fixture and an end face pressure plate on an L-shaped base, enabling multi-process machining of irregular workpieces in one clamping. The floating wedge compensation mechanism provides high rigidity support to eliminate bending deformation and chatter.

Benefits of technology

This technology enables multi-process machining of irregularly shaped workpieces in a single setup on a horizontal machining center, reducing positioning errors, improving machining accuracy and efficiency, and suppressing workpiece deformation and chatter.

Abstract

The application discloses a multi-process milling clamp for processing special-shaped workpieces and belongs to the technical field of machining clamps. The clamp comprises a horizontal fixing plate, a vertical plate fixed to the horizontal fixing plate, a center pin fixed to the horizontal fixing plate, a floating wedge compensation mechanism installed on the vertical plate, a hook type clamp installed on the same side of the vertical plate and an end face pressing plate. The floating wedge compensation mechanism comprises a screw rod, a nut seat, a first wedge and a second wedge, the second wedge is fixed to the vertical plate and is provided with a T-shaped groove, the first wedge is provided with a T-shaped sliding block and is in sliding fit with the second wedge through a slope, the screw rod is vertically connected to the nut seat, the lower end is clamped into a clamping groove at the top end of the first wedge, the first wedge is driven to slide along the T-shaped groove to adjust the extension amount of the first wedge in the direction perpendicular to the vertical plate and abut against the surface to be supported of the workpiece. The hook type clamp laterally presses the workpiece, and the end face pressing plate vertically presses the workpiece. The clamp realizes the completion of multiple processes through one-time clamping, and improves the machining precision and efficiency.
