Technical Field

[0001] The utility model relates to the technical field of camshaft production, in particular to a camshaft production and processing positioning device. 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, its speed is usually still very high and it needs to withstand a large torque. Therefore, the design has very high requirements for the strength and support of the camshaft. Its material is generally high-quality alloy steel or alloy steel. Since the movement of the valve 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. The camshaft needs to use production and processing equipment during the production process.

[0004] The above scheme also has the following technical defects: the above scheme is not convenient for clamping the camshaft, because the camshaft needs to be clamped during the processing to prevent the camshaft from moving during the processing; and the camshaft needs to be precisely positioned during the drilling process, and it is difficult to position the camshaft manually. Based on this, a camshaft production and processing positioning device is proposed. Utility Model Content
