Description

Technical Field

[0001] The utility model relates to the technical field of a clamp for machining a camshaft front bearing cover, in particular to a clamp for machining a camshaft front bearing cover. Background Art

[0002] As we all know, the camshaft is a component in a piston engine, and its function is to control the opening and closing of the valve. Although the speed of the camshaft in a four-stroke engine is half of that of the crankshaft (in a two-stroke engine, the speed of the camshaft is the same as 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 valve movement law 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. In the prior art, when the operator processes the camshaft front bearing cap, the clamp used to clamp the camshaft front bearing cap is not effective, which may cause the camshaft front bearing cap to shake due to the poor clamping effect, making it difficult for the operator to process the camshaft front bearing cap, reducing the operator's work efficiency.

[0003] A camshaft front bearing cover processing fixture with Chinese utility model application number CN202220604101.X is provided. After the camshaft front bearing cover is fixed, it is not easy to shake. However, it is inconvenient to place the camshaft front bearing cover in a fixed position when fixing it. The pressure block head will block the camshaft front bearing cover when fixing it. Therefore, we propose a camshaft front bearing cover processing fixture to solve the above problem.
