Problems solved by technology

[0002] Most of the camshaft parts in automobiles, engines, internal combustion engines, and oil pumps are convex. With the improvement of environmental protection requirements and the continuous improvement of internal combustion engine emission standards, the number of cams with concave surfaces continues to increase. Traditional cams with concave composite surfaces The processing method mainly adopts the processing technology of profiling lathe turning and then polishing. This method or device has the following problems: 1. The precision of profiling turning is not high and the error is large
2. Every kind of parts needs to make profiling, the production cycle is long and cannot meet the production requirements
3. Polishing has an impact on the accuracy of the shape line, and the roughness does not meet the requirements

Abstract

The invention discloses a method and a device for realizing convex-concave composition plane non-circular grinding, the method comprises the following steps: using following grinding method with a large and a small grinding wheel, performing coarse grinding and semi-accurate grinding to the cam line with the large grinding wheel, leaving an accurate grinding margin of 0.05-0.15 mm, and then performing accurate grinding and concave grinding with the small grinding wheel to meet the technical requirements of drawings. The invention provides a convex-concave composition plane non-circular grinding method with high production efficiency and higher processing precision. The device for realizing the convex-concave composition plane non-circular grinding method has simple structure and reliable performance.

Description

technical field [0001] The invention relates to a non-circular grinding method for a convex-concave composite surface, in particular to a grinding method for a camshaft with a convex-concave composite surface, and also relates to a device for realizing the non-circular grinding method for a convex-concave composite surface. Background technique [0002] Most of the camshaft parts in automobiles, engines, internal combustion engines, and oil pumps are convex. With the improvement of environmental protection requirements and the continuous improvement of internal combustion engine emission standards, the number of cams with concave surfaces is increasing. The traditional cam with concave composite surfaces The processing method mainly adopts the processing technology of profiling lathe turning and then polishing. This method or device has the following problems: 1. The precision of profiling turning is not high and the error is large. 2. Each part needs to make a model, and th...
