[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 existing camshaft press-fitting fixtures still have some defects. During use, most camshaft press-fitting fixtures easily cause damage to the camshaft surface during the clamping process, thereby reducing the service life of the camshaft. For this reason, we propose a camshaft press-fitting fixture. Utility Model Content
