An automatic grinding and polishing process for titanium alloy ring castings

Abstract

The invention provides an automatic grinding and polishing process for a titanium alloy annular casting. An automatic grinding and polishing system for the titanium alloy annular casting mainly comprises a base, an outer cover, an industrial robot, an electric main shaft, a rotating workbench, a positioning clamp, a water tank, a cooling chip removal machine, a PLC and a display screen. The titanium alloy annular casting is positioned and clamped on the surface of the rotating workbench through the clamp; the robot clamps the electric main shaft to move according to a certain trajectory so that the grinding and polishing work of the titanium alloy annular casting is realized, moreover, multiple kinds of sensors are adopted for cooperation to adjust a machining path so as to adapt to the complicated contour and shape difference of a part, therefore, the automatic grinding and polishing system for the titanium alloy annular casting has a wide application prospect in titanium alloy annular casting machining, the production efficiency can be improved, and considerable benefits can be brought to enterprises.

Description

technical field [0001] The invention relates to a grinding and polishing process, in particular to an automatic grinding and polishing process for titanium alloy annular castings. Background technique [0002] With the arrival of Made in China 2025, the application of industrial robots is becoming more and more extensive. In the aircraft manufacturing industry, many parts are made of titanium alloy, and their blanks are mostly produced by casting. After the titanium alloy is cast, an oxide layer will form on its surface, and there will be small cracks on the surface of its rounded corners, which is not conducive to subsequent processing and the use of finished products. Therefore, after the casting is completed, the surface of the titanium alloy needs to be ground and polished, especially the fillet of the titanium alloy casting. The use of robotic grinding and polishing can improve processing efficiency, ensure processing accuracy, and reduce grinding and polishing costs....

AI Technical Summary

Problems solved by technology

The grinding and polishing of titanium alloy ring castings mainly has the following three problems: 1. The radial dimension of titanium alloy ring castings is large, reaching more than 900mm, and it is difficult to clamp in general machining centers. 2. The surface contour of titanium alloy ring castings is complex, with planes, Arc surfaces, rounded corners, intersecting lines, etc., require a 6-axis machine tool to process the surface

3. Titanium alloy annular casting is used as a casting, its actual size and appearance are different from the theoretical value on the drawing, and it is impossible to complete the setting of the processing track by offline programming
