An automatic grinding and polishing system for titanium alloy ring castings

Abstract

The invention provides an automatic polishing system for an annular titanium alloy casting. The automatic polishing system for the annular titanium alloy casting mainly comprises a base, an outer cover, an industrial robot, an electric spindle, a rotating workbench, a locating clamp, a water channel, a cooling and chip discharging machine, a PLC and a display screen. The annular titanium alloy casting is located and clamped to the surface of the rotating workbench through the clamp. The electric spindle is installed at the tail end of the industrial robot. The electric spindle is provided witha cutter. The automatic polishing system for the annular titanium alloy casting achieves automatic polishing of the annular titanium alloy casting, the polishing efficiency and polishing quality areboth higher than those of manual polishing, and manpower used in polishing is reduced; and therefore, the automatic polishing system for the annular titanium alloy casting has broad application prospects in machining of the annular titanium alloy castings and can improve production efficiency and bring considerable benefits for an enterprise.

Description

technical field [0001] The invention relates to a grinding and polishing system, in particular to an automatic grinding and polishing system 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
