[0003] The function of the cylinder head is to seal the cylinder. In the production process of the air compressor cylinder head, the cylinder head is formed by stamping or casting a cylinder head mold.

The clamping block 5 is fixed on the top wall of the trapezoidal slider 21. The movement of the trapezoidal slider 21 will drive the clamping block 5 to move synchronously, so that each clamping block 5 can clamp and fix the cylinder head.

[0023] A moving block 7 is slidingly provided on the top of the processing box 1, and an electric push rod 8 is fixed at the bottom of the moving block 7. A protective box 9 is installed on the piston rod of the electric push rod 8. A driving motor 2 10 is installed in the protective box 9.

A moving assembly 12 for moving the moving block 7 is also provided on the top of the processing box 1. After the cylinder head is clamped, the electric slide rail 4 can be used to indirectly push the cylinder head to move forward and backward. When the cylinder head moves to the specified position, the moving assembly 12 can be started to indirectly drive the drill bit through the moving assembly 12 to achieve left and right movement, thereby moving the drill bit to the position of the cylinder head to be drilled.

[0024] The moving assembly 12 includes a screw rod 22 and a drive motor 3 23. A limit slot 24 is also provided on the inner top wall of the processing box 1. The screw rod 22 is rotatably arranged in the limit slot 24. The drive motor 3 23 is fixed to the outside of the processing box 1. The output shaft of the drive motor 3 23 passes through the processing box 1 and is fixed to the screw rod 22. The moving block 7 is threadedly matched with the screw rod 22. The top end of the moving block 7 is slidably arranged in the limit slot 24.

When the drill bit moves to the specified position, the electric push rod 8 can be started, and the electric push rod 8 can push the protection box 1 9 and the drill chuck 11 to move. During the movement of the drill chuck 11, the driving motor 2 10 will be started, and the driving motor 2 10 can drive the drill chuck 11 to rotate, and the drill chuck 11 will drive the drill bit to rotate to realize drilling processing.

[0025] A cavity 13 is provided inside the processing box 1, and coolant is provided in the cavity 13. A cooling component 14 for cooling the drilling process is also provided in the processing box 1. During the drilling process, the cooling component 14 can be started to cool the drill bit to prevent the drill bit from being affected by excessive temperature and affecting the drill bit life and grinding quality.

[0026] The cooling assembly 14 includes a delivery pipe 25 and a liquid pump 26. The liquid pump 26 is installed on the back of the processing box 1. When the drill bit needs to be cooled during drilling, the liquid pump 26 can be started first. One end of the delivery pipe 25 is connected to the cavity 13 of the processing box 1, and the other end of the delivery pipe 25 passes through the processing box 1 and is connected to the liquid pump 26. The delivery pipe 25 extracts the coolant in the cavity 13 through the liquid pump 26. The liquid outlet end of the liquid pump 26 is connected to a drain pipe 27. The liquid pump 26 will discharge the coolant into the drain pipe 27. A diverter is installed at one end of the drain pipe 27 away from the delivery pipe 25. Two connecting pipes 28 are installed on the diverter. One end of the two connecting pipes 28 passes through the processing box 1 and corresponds to the drill chuck 11. The coolant flows into the two connecting pipes 28 through the diverter, and can be sprayed to the drill bit on the drill chuck 11 through the connecting pipe 28, thereby cooling the drill bit.

The connecting pipe 28 is a flexible telescopic pipe structure. The connecting pipe 28 passes through the fixing blocks 29 when entering the processing box 1, thereby supporting the connecting pipe 28. Since the protection box 9 will be lifted and lowered, the connecting pipe 28 is designed to be a flexible telescopic pipe structure to facilitate the adjustment of its length. The connecting pipe 28 can adopt a corrugated pipe structure.

The coolant sprayed from the connecting pipe 28 can return to the cavity 13 through the connecting hole 30 for reuse, and the waste chips generated by drilling are filtered through the filter screen to prevent them from entering the cavity 13. Part of the coolant will enter the support frame 2 through the trapezoidal slide 20 on the processing table 3. The coolant can be discharged by providing a through hole at the bottom of the support frame 2, and the drive motor 17 is protected by installing the protection box 2 31.

[0029] Working principle: When processing the compressor cylinder head, first place the cylinder head between the clamping blocks 5 and start the driving assembly 6. The driving assembly 6 rotates through the second bevel gear 16 to drive the screw 19 to rotate. The trapezoidal slider 21 is driven by the screw 19 to slide so that the clamping blocks 5 can slide. The cylinder head is clamped and fixed by the synchronous sliding of the clamping blocks 5.

[0030] After the cylinder head is clamped and fixed, the electric slide rail 4 can be started to drive the support frame 2 to move, and then the support frame 2 drives the processing table 3 and the cylinder head on top of it to move forward and backward, and then the moving component 12 is started. The moving component 12 drives the moving block 7 to slide in the limiting slide groove 24 through the screw 22, so that the moving block 7 can move left and right, and finally the drill bit can be moved to the processing position of the cylinder head.

[0031] When the position adjustment of the drill bit is completed, the drive motor 10 can be started, and the drill chuck 11 can be driven to rotate by the drive motor 10. The drill bit will be installed on the drill chuck 11, and the drill bit can be driven to rotate by the drill chuck 11. At this time, the electric push rod 8 is started to push the drill bit to achieve height adjustment, thereby realizing the drilling processing of the cylinder head.

[0032] When drilling, the cooling component 14 can be started, and the cooling component 14 can extract the coolant in the cavity 13 through the liquid extraction pump 26. The coolant is discharged through the connecting pipe 28 to cool the drill bit. The ejected coolant can then return to the cavity 13 through the connecting hole 30 for reuse.
