Technical Field

The invention relates to the field of camshaft polishing, in particular to automatic camshaft polishing equipment, and belongs to the technical field of polishing.

Background

The camshaft is a component in a piston engine. Its function is to control the opening and closing action of the valve. Although the rotational speed of the camshaft is half of that of the crankshaft in a four-stroke engine (the rotational speed of the camshaft is the same as that of the crankshaft in a two-stroke engine), the rotational speed is still high and the camshaft is subjected to a large torque, so that the camshaft is required to be high in strength and support in design, and the camshaft is generally made of high-quality alloy steel or alloy steel. Because the valve motion law is related to the power and the running characteristics of an engine, the camshaft design occupies a very important position in the design process of the engine. Polishing refers to a process of reducing the roughness of a workpiece surface by mechanical, chemical, or electrochemical actions to obtain a bright, flat surface. The method is to carry out modification processing on the surface of a workpiece by using a polishing tool and abrasive particles or other polishing media. The camshaft is a component in a piston engine. Its function is to control the opening and closing action of the valve. Although the rotational speed of the camshaft is half of that of the crankshaft in a four-stroke engine (the rotational speed of the camshaft is the same as that of the crankshaft in a two-stroke engine), the rotational speed is still high in general and the camshaft is required to bear large torque, so that the camshaft is required to be high in strength and support in design, and the camshaft is usually made of special cast iron and occasionally forged.

The prior camshaft has poor intelligence in the polishing process, low automation degree, few polishing modes and general polishing effect.
