[0005] For further improvement, the base plate, positioning plate and movable plate are parallel to each other, and an opening is also provided on the base plate. While the base plate meets the installation and support requirements, the opening is provided to reduce its own weight. The movable plate moves up and down smoothly between the base plate and the positioning plate. The movable plate always remains horizontal during the up and down movement. The cylinder head cover provided on the movable plate also remains horizontal, and the stability is enhanced.

[0006] To further improve, there are two flat-head elastic pins and two tapered elastic pins. The two flat-head elastic pins and the two tapered elastic pins correspond to the four inner holes of the cylinder head cover. While the cylinder head cover is positioned in the X and Y directions, the two flat-head elastic pins and the two tapered elastic pins provide sufficient support to the cylinder head cover, so that the cylinder head cover remains stable.

[0007] For further improvement, there are three clamping cylinders, three movable holes opened in the movable plate, and three clamping blocks pass through the three movable holes respectively, thereby increasing the movable space of the clamping cylinders and the clamping blocks and preventing the movable plate from contacting and colliding with the clamping blocks during the rising process.

[0012] For further improvement, two throttle valves are respectively arranged on the sides of the lifting cylinder and the clamping cylinder, and the inner tube has two groups of air inlet and air outlet. One throttle valve adjusts the size of the air inlet of the lifting cylinder or the clamping cylinder, and the other throttle valve adjusts the size of the air outlet of the lifting cylinder or the clamping cylinder. The operation is simple and convenient to use.

[0013] The beneficial effects of the present invention are:

[0014] 1. The cylinder head cover is placed on the top of the flat elastic pin and the tapered elastic pin. The inner hole of the cylinder head cover corresponds to the flat elastic pin and the tapered elastic pin. The tapered elastic pin and the flat elastic pin reach the inside of the inner hole. The cylinder head cover is positioned in the X and Y directions. The hand-pull valve is pulled. Due to the effect of the throttle valve, the lifting cylinder is retracted and the lifting cylinder drives the movable plate to move upward smoothly. The cylinder head cover is pulled up to the Z direction positioning surface. The top of the cylinder head cover and the bottom of the positioning column are against each other. The clamping cylinder is operated and clamped. The cylinder contracts and drives the clamp to move upward quickly. The clamp clamps the cylinder head cover below the positioning contact surface, and the cylinder head cover is fixed. The milling machine runs, and the milling cutter passes through the opening to mill the surface of the cylinder head cover. After the processing is completed, the hand-pull valve is pulled, the clamping cylinder is released, the clamp moves away from the cylinder head cover, and the lifting cylinder extends and runs. The lifting cylinder drives the movable plate to return to its position smoothly, and the whole action process is completed. The whole process effectively clamps and fixes the cylinder head cover, which is convenient for operation and improves processing efficiency. The enhanced stability improves the processing effect.

[0015] 2. While strengthening the support through the optical axis, the movable plate is effectively limited to prevent the movable plate from moving up and down. The linear bearing interacts with the optical axis to reduce friction and improve smoothness. The two lifting cylinders have balanced forces and the two optical axes have balanced limits, which further ensures that the movable plate and the cylinder head cover move up and down smoothly to the precise position. The setting of the groove saves space and the weight of the movable plate itself is also reduced. BRIEF DESCRIPTION OF THE DRAWINGS
