[0025] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0026] See attached document Figure 1 To be continued Figure 4 As shown, a grinding device with auxiliary support includes a main shaft 1, a grinding rod 2 disposed at the output end of the main shaft 1, a grinding wheel 3 sleeved on the grinding rod 2, a support assembly 4 disposed at the end of the grinding rod 2 away from the main shaft 1, and a sleeve 6 disposed on the outside of the grinding rod 2.

[0027] In one embodiment of this utility model, the support component 4 includes a mounting plate 41 disposed on the outside of the grinding wheel 3, a fixing block 42 disposed between the mounting plate 41 and the grinding rod 2, and a sealing ring 43 made of rubber material sleeved on the fixing block 42. The sealing ring 43 is an O-ring. The mounting plate 41 is fan-shaped. One end of the mounting plate 41 is connected to the sleeve 6, and the other end of the mounting plate 41 is sleeved on the fixing block 42. The sealing ring 43 ensures airtightness.

[0028] In one embodiment of this utility model, an annular groove 421 is provided on the outer circular surface of the fixing block 42, and the sealing ring 43 is located below the annular groove 421. An inlet pipe 411 communicating with the annular groove 421 is provided in the mounting plate 41. The inlet pipe 411 is a gas or liquid inlet pipe. The inlet pipe 411 is arranged along the length direction of the mounting plate 41, and the groove width of the annular groove 421 is larger than the inner diameter of the inlet pipe 411. This ensures that after the annular groove 421 is uniformly filled with gas or liquid, sufficient pressure is formed to achieve the effect of air flotation auxiliary support or liquid auxiliary support for the grinding rod 2.

[0029] In one embodiment of this utility model, four output holes 5 are uniformly provided in the annular groove 421 to guide gas to the grinding rod 2. The output holes 5 are gas or liquid output holes. The four output holes 5 are symmetrical in pairs and are all perpendicular to the grinding rod 2. They are located at the quarter-end of the fixing block 42 respectively. The diameter of the output holes 5 is set between 0.08-0.12mm, preferably 0.1mm, to ensure efficiency and stability when gas or liquid is introduced.

[0030] In one embodiment of this utility model, an inlet 7 is provided at the end of the inlet pipe 411 away from the fixed block 42. The inlet 7 is an air inlet or a liquid inlet. The inner diameter of the inlet 7 is set to be larger than the inner diameter of the inlet pipe 411, and the output end of the inlet pipe 411 is set directly opposite the annular groove 421 to further improve the air or liquid filling efficiency.

[0031] In one embodiment of this utility model, the spindle 1 can be a BT30 electric spindle or a mechanical spindle. The rotation of the spindle 1 drives the grinding wheel 3 to rotate, thereby grinding the valve plate groove of the workpiece. Furthermore, air or liquid is introduced from the inlet 7, so that the annular groove 421 is uniformly filled with gas or liquid, forming pressure. Then, the gas or liquid is uniformly guided to the grinding rod 2 through the outlet hole 5, thereby playing the role of air flotation auxiliary support or liquid auxiliary support, so as to enhance the rigidity of the grinding rod 2, making the grinding rod 2 more stable during grinding, which is conducive to improving the groove verticality, straightness and groove width accuracy of the processed valve plate groove.
