[0022] Example 1: Please refer to Figures 1-3 A gear pump end face machining fixture includes a fixture table 1, a fixture structure 2, a protective cover 3, and a dust collection component 4. The fixture structure 2 and the protective cover 3 are both located at the upper end of the fixture table 1, and the protective cover 3 is placed on the outside of the fixture structure 2. The dust collection component 4 is located on the side wall of the fixture table 1. The protective cover 3 is used to cover the fixture structure 2 and to machine the gear pump end face with the help of the fixture structure 2. The dust collection component 4 is used to effectively collect dust, making it difficult for dust to spread and facilitating centralized treatment.

[0023] The dust collection assembly 4 includes an air pump 41 and a conduit 44 and a connecting pipe 42 connected to the two ends of the air pump 41, respectively. One end of the connecting pipe 42 extends into the tooling table 1, and the other end of the conduit 44 is connected to an annular pipe 45. The annular pipe 45 is located on the outside of the tooling structure 2. Small holes for ventilation are evenly opened on the surface of the annular pipe 45, allowing gas to be discharged from the small holes. The tooling table 1 has a groove 12 and a storage cavity 14 inside. A connecting hole 13 is opened on the surface of the groove 12, and the groove 12 and the storage cavity 14 are connected through the connecting hole 13. A filter screen 43 for dust filtration is installed inside the storage cavity 14. A dust removal component 46 is also connected to the upper end of the annular pipe 45. When the air pump 41 is started, the connecting pipe 42 draws in air, allowing the gas to carry dust into the storage cavity 14 and be filtered through the filter screen 43. Then, the gas is discharged through the conduit 44 and the annular pipe 45. The gas blown out by the annular pipe 45 can cool the tooling structure 2.

[0024] The tooling structure 2 includes a fixing plate 21 and a sealing coating 26 uniformly coated on the outer wall of the fixing plate 21. The fixing plate 21 is provided in two sets. One set of the fixing plate 21 has a motor 22 installed on the outer side, and the annular tube 45 is placed on the outer side of the motor 22. The other set of the fixing plate 21 has a translation member 24 installed on the inner side. The output end of the motor 22 is connected to a grinding head 23 through a shaft, and the grinding head 23 is located on the inner side of the fixing plate 21. The inner side of the translation member 24 has a clamping member 25, which is used to clamp the gear pump.

[0025] The translation component 24 includes a frame 241 and a cylinder component 242 installed inside the frame 241. The telescopic end of the cylinder component 242 is connected to a mounting base 243. When the cylinder component 242 is activated, it can push the mounting base 243 to move, thereby realizing the horizontal movement of the mounting base 243.

[0026] The clamping component 25 includes a platform 251 and an electric push rod 252 installed inside the platform 251. The telescopic end of the electric push rod 252 is connected to a clamping ring 253. The platform 251 is fixed on the mounting base 243. When the mounting base 243 moves, the clamping component 25 also moves. The platform 251, the electric push rod 252 and the clamping ring 253 are all provided in two sets for clamping the gear pump. When the two sets of electric push rods 252 are started, they can push the clamping ring 253 to move respectively. The two sets of clamping rings 253 move closer to each other and can clamp the gear pump.

[0027] The surface of the tooling table 1 is also provided with a sliding groove 11. A door 15 is hinged to the side wall of the tooling table 1. A dustproof and breathable mesh 31 is embedded in the surface of the protective cover 3. A slider 32 is fixedly installed at the lower end of the protective cover 3. The slider 32 slides in the sliding groove 11. The inner wall of the sliding groove 11 is also coated with a sealing coating 26. When the slider 32 slides in the sliding groove 11 and the protective cover 3 covers the tooling structure 2, it is fixed with bolts so that the protective cover 3 is stable at the upper end of the tooling table 1.

[0028] In this embodiment: During the process, the gear pump is held by the clamping member 25, and with the cooperation of the translation member 24, the end face of the gear pump is brought close to the grinding head 23. Then, the slider 32 is pushed to slide in the slide groove 11. When the protective cover 3 covers the tooling structure 2, it is fixed by bolts, so that the protective cover 3 is firmly fixed at the upper end of the tooling table 1, which can be sealed. It is also sealed by the sealing coating 26. Then, the motor 22 and the grinding head 23 are used for processing. During grinding, the air pump 41 is started, and the connecting pipe 42 draws in air, so that the gas carries the dust into the storage cavity 14. The dust is filtered through the filter screen 43, allowing it to be collected in the storage chamber 14 and prevented from spreading. Then, the exhaust is carried out through the conduit 44 and the annular pipe 45. The gas blown out by the annular pipe 45 can cool the motor 22, effectively reducing its temperature and extending its service life. At the same time, the gas can circulate within the space enclosed by the protective cover 3 and the two sets of fixing plates 21, and external impurities are blocked from entering the protective cover 3 by the dustproof and breathable net 31. When the gas circulates, it can also carry away the heat from the grinding head 23 and the end face of the gear pump.

[0029] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 4 The dust removal component 46 includes a diversion pipe 461 and an air jet pipe 462 connected to one end of the diversion pipe 461. The diversion pipe 461 is connected to the annular pipe 45. A valve is provided on the diversion pipe 461. The air jet pipe 462 is located above the grinding head 23. Nozzles for air jetting are evenly distributed at the lower end of the air jet pipe 462. By controlling the valve, gas can enter the diversion pipe 461 from the annular pipe 45 and finally be ejected from the air jet pipe 462.

[0030] In this embodiment: After grinding, the valve on the diversion pipe 461 is opened, allowing gas to enter the diversion pipe 461 through the annular pipe 45 and be ejected through the jet pipe 462, which can remove the dust on the surface of the grinding head 23 and clean the grinding head 23.
