Description

Camshaft cross slide grinder

technical field

The invention relates to the technical field of auto parts processing equipment, in particular to a camshaft cross slide grinder.

Background technique

Camshafts are widely used in gasoline engines or diesel engines to control the opening and closing of fuel injection pumps or the opening and closing of intake and exhaust valves. The quality of their processing directly determines the performance of the engine.

The camshaft is generally cast by mold, and the surface of the cast camshaft is generally rough, but the camshaft runs at high speed in the engine and requires very high smoothness. At present, the grinding and finishing of the camshaft is usually performed by a CNC camshaft grinder. During grinding, the camshaft is placed in the clamping mechanism, and the clamping mechanism drives the workpiece to rotate. Through the linkage between the feed movement of the grinding mechanism and the rotational movement of the workpiece, the camshaft that meets the requirements can be processed.

However, the current camshaft grinder is not only inconvenient to adjust the position of the camshaft and the grinding wheel, but also very slow to adjust, resulting in a relatively low grinding efficiency of the entire camshaft.
