[0002] A camshaft is a component in a piston engine. Its function is to control the opening and closing actions of the valves. Although the rotational speed of the camshaft is half of that of the crankshaft in a four-stroke engine, generally its rotational speed is still very high and it needs to withstand a large torque. Therefore, in the design, the requirements for the camshaft in terms of strength and support are very high. After the camshaft is processed, it is necessary to remove burrs and grind the camshaft.

[0003] The patent with the application number 202420023330.1 discloses a grinding device for camshaft processing, including a base, a clamping cylinder, a movable seat and a glass cover. A plurality of positioning slot holes are evenly arranged at equal intervals on one side of the top end of the base. A fixed seat is fixedly connected to the middle position on one side of the top end of the base. A sliding rod is fixedly connected to the middle position on one side inside the base. By arranging a plurality of groups of positioning slot holes at the top end of the base and inserting the positioning rod in the hollow block on one side of the movable seat into the positioning slot holes on the base, the position of the movable seat at the top end of the base can be fixed. Then, when adjustment is required according to camshafts of different lengths, by inserting the positioning rod at the bottom end of the hollow block into the positioning slot holes at different positions on the base, the position of the movable seat at the top end of the base can be fixed, thereby realizing the clamping and limiting work for camshafts of different length specifications.

[0004] In view of the above related technologies, by inserting the positioning rod at the bottom end of the hollow block into the positioning slot holes at different positions on the base, the position of the movable seat at the top end of the base can be fixed, thereby realizing the clamping and limiting work for camshafts of different length specifications. However, this device is not provided with a structure for absorbing waste chips. When the device grinds the camshaft, waste chips may be generated, polluting the environment and even possibly affecting the working state of the staff. Content of the Utility Model

And the clamping assembly has a rotating function, which is convenient for subsequent grinding of the device. When the camshaft is clamped, making the grinding assembly contact the side wall of the camshaft can play a role in grinding the camshaft.
