[0024] See also Figure 1 、 Figure 2 、 Figure 4 The connecting mechanism 9 includes an oblique groove 91, an oblique block 92 is slidably connected inside the oblique groove 91, and the oblique block 92 is slidably connected to the clamping block 6.

[0025] The specific implementation process of the utility model is as follows: when in use, the camshaft is first inserted into the interior of the clamping block 6, and then the electric push rod 4 is started. The output end of the electric push rod 4 will drive the mounting base 5 and the clamping block 6 to move, and the clamping position of the camshaft can be achieved through the movement of the clamping block 6. After the camshaft is positioned, the motor 10 is started. The output end of the motor 10 can drive the first bevel gear 11 to rotate, and the first bevel gear 11 can drive the second bevel gear 12 to rotate, so as to realize the rotation of the rotating base 3. The rotating base 3 can drive the clamping block 6 and the camshaft to rotate, making it convenient to process different positions of the camshaft.

[0026] When the rotating seat 3 rotates, the arc surface of the groove 81 inside the rotating seat 3 will squeeze and push the ball 82 to move, and the ball 82 will drive the slider 84 and the slide rod 85 to move downward. The slider 84 squeezes the first spring 86, which can separate the ball 82 from the groove 81. As the rotating seat 3 rotates, the elastic action of the first spring 86 will give the slider 84 an upward thrust, which can push the ball 82 into the groove 81 at another position. At this time, the rotating seat 3 can be limited after rotation to prevent the rotating seat 3 and the camshaft from rotating at will, which is convenient for subsequent processing.

[0027] When it is necessary to disassemble the clamping block 6, the clamping block 6 is directly pulled horizontally, and the clamping block 6 drives the inclined block 92 to move. The inclined block 92 slides along the inclined surface of the inclined groove 91, and the inclined block 92 will be squeezed to slide toward the inside of the clamping block 6. The inclined block 92 slides along the guide block 94. At the same time, the inclined block 92 will squeeze the second spring 95, which can separate the inclined block 92 from the inclined groove 91. The clamping block 6 can then be pulled out from the inside of the mounting seat 5, which can realize the rapid replacement of the clamping block 6, facilitate the replacement of the clamping block 6, and can be adapted to camshafts of different sizes for positioning.
