CN224073858U - Auxiliary processing device for universal profile hole site - Google Patents

Abstract

This utility model discloses a universal profile hole-machining auxiliary device, including a base plate, a positioning plate, and a pressure plate. The base plate has several positioning holes and several threaded holes. The positioning holes are arranged in a straight line, and the threaded holes are also arranged in a straight line, with the lines formed by the two being parallel to each other. Positioning pins are inserted into the positioning holes. The positioning plate is positioned by the positioning pins and clamps the part to be processed onto the base plate. Bolts pass through the through holes on the pressure plate and engage with the threaded holes on the base plate to fix the part to be processed and the positioning plate onto the base plate. It has the advantages of high positioning and locking to ensure high accuracy and effectively prevent the part from shifting during processing. It improves efficiency with a single installation: hole processing can be completed with only one installation, avoiding multiple clamping of the part and reducing installation errors caused by multiple clamping. At the same time, the tooling is universal. Only the positioning plate needs to be replaced to perform hole processing on the same type of profile, which helps to save processing tooling costs.
