Description

Technical Field

[0001] The utility model relates to the technical field of camshaft processing, in particular to a processing tool for an oil pump camshaft. Background Art

[0002] The camshaft is a component in a piston engine. Its function is to control the opening and closing of the valves. Although the speed of the camshaft in a four-stroke engine is half that of the crankshaft (in a two-stroke engine, the camshaft speed is the same as the crankshaft), its speed is usually still very high and it needs to withstand a large torque. Therefore, the design of the camshaft has high requirements for strength and support, and its material is generally high-quality alloy steel or alloy steel. Since the movement of the valves is related to the power and operating characteristics of an engine, the camshaft design occupies a very important position in the design process of the engine.

[0003] The camshaft will be subjected to great pressure during the rotation process. If the edge is sharp, it is more likely to crack and thus cause greater mechanical failure. This risk can be reduced by chamfering. However, the clamping tooling currently used is difficult to quickly clamp and position the camshaft during use, resulting in relatively low work efficiency. For this reason, a pump camshaft processing tooling is proposed to assist in chamfering the camshaft. Utility Model Content
