Abstract

The invention relates to a dimension correction device in large double-curved surface plate part processing; a T-shaped groove in a rectangular direction is arranged on the upper surface of the workbench surface of a milling machine, and a plurality of connecting bolts are arranged in the T-shaped groove; and one end of a pressure plate is provided with a long strip hole and the other end of the pressure plate is provided with a reverse support bolt, wherein the long strip hole is connected with the connecting bolt, and the bottom surface of the support bolt is contacted with the surface of the workbench surface of the milling machine. According to the correction device, the structure is simple, the correction method is easy and convenient, simultaneously the working efficiency is improved, the problems of a large vacuum absorption platform that the fixation is not firm and the hole positioning stress cannot be released are solved, and the number of various other positioning clamps in processing is greatly reduced.

Description

technical field [0001] The invention relates to a size correction device and a method for processing large-scale hyperboloid plate parts, which are used to prevent deformation of the parts during processing. Background technique [0002] In the original CNC machining, the combination of large vacuum adsorption platform and hole positioning is mostly used to fix the processed parts and prevent the position of the parts from moving during processing. Hole positioning generally uses a separate positioning hole on the part, fixed positioning with a positioning pin, or positioning according to the process hole of the part itself, or making a process positioning hole positioning on the outer edge of the part according to the shape and structural characteristics of the part. [0003] For the large vacuum adsorption platform in this method, the surface of the large hyperboloid plate parts is not flat, so the vacuum suction cups of multiple fixed parts of the large vacuum adsorption ...
