[0002] A camshaft is a component in a piston engine, and its function is to control the opening and closing actions of the valves. Currently, when machining the central hole of a camshaft, an operator needs to manually fix the camshaft to be machined in the machining device first to drill one end of the camshaft, and then the operator flips the cam 180 degrees and fixes it in the machining device again to drill the other end of the camshaft. This will affect the work efficiency to a certain extent, and cannot well meet the machining requirements. Moreover, due to the two-time clamping, positioning errors are likely to occur, resulting in low drilling accuracy of the camshaft.

This device enables the turntable 2 to rotate through the driving mechanism, so that the camshaft can rotate during clamping, reducing the processes during camshaft processing, and the clamping of the camshaft by the device is also convenient, increasing the convenience during the use of the device;

[0021] Further, the driving mechanism includes a gear 6, the gear 6 is rotatably mounted on the mounting bracket 1, tooth grooves 7 are arrayed on the turntable 2, a motor 8 is fixedly mounted on the mounting bracket 1, and the output shaft of the motor 8 is connected to the central position of the gear 6. This structure enables the turntable 2 to rotate, so that the camshaft can rotate during processing, increasing the functionality during the use of the device.

[0022] Further, a slider 9 is fixedly mounted on the movable block 3, a chute 10 is opened on the turntable 2, the slider 9 slides in the chute 10, rollers 11 are arrayed and rotatably mounted on the lower side of the slider 9, and a first spring 12 is arranged in the chute 10, and the first spring 12 abuts against the slider 9. This structure enables the extrusion block 4 to press and extrude the camshaft under the action of the first spring 12, increasing the stability during the use of the device.

[0023] Further, a guide rod 13 is fixedly installed on the slider 9, the first spring 12 is sleeved on the guide rod 13, guide grooves 14 are formed on the left and right sides of the chute 10, the guide rod 13 is inserted into the guide grooves 14, a shielding block 15 is fixedly installed on the front side of the extrusion block 4, and the shielding block 15 shields the chute 10.
