A plurality of mounting plate through holes for loading the water pump thrust plate are arranged in the middle of the thrust plate mounting plate. A plastic film is arranged on the top surface of the thrust plate mounting plate so that after the water pump thrust plate is soaked in clear water, the water pump thrust plate is adsorbed and fixed on the mounting plate through holes by the surface tension of the clear water. The water pump thrust plate is adsorbed and fixed on the mounting plate through holes by the surface tension of the clear water, and after polishing is completed, the water pump thrust plate is separated from the mounting plate through holes by soaking in clear water, realizing the functions of quick locking and disassembly separation of the water pump thrust plate.

[0016] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings.

[0017] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly. In addition, the descriptions involving "preferred", "sub-preferred", etc. in the utility model are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined as "preferred" and "sub-preferred" may explicitly or implicitly include at least one of the features.

[0018] Such as Figures 1 - 3As shown in the figure, a polishing fixture for a water pump thrust disc includes a fixture base 1 and a thrust disc mounting plate 2. At the position near the edge of the bottom surface of the fixture base 1, there are multiple positioning bumps 3. The thrust disc mounting plate 2 is arranged on the bottom surface of the fixture base 1, and at the edge position of the thrust disc mounting plate 2, there are multiple positioning notches 4 respectively corresponding to the positioning bumps 3. At the middle position of the thrust disc mounting plate 2, there are multiple mounting plate through holes 5 for the water pump thrust disc to be inserted. On the top surface of the thrust disc mounting plate 2, there is a plastic film, so that after the water pump thrust disc is soaked in clear water, the water pump thrust disc is adsorbed and fixed on the mounting plate through holes 5 by the surface tension of the clear water. Before polishing, soak the water pump thrust disc in water, set a plastic film on the top surface of the thrust disc mounting plate 2, then put the water pump thrust disc soaked in clear water into the mounting plate through holes 5 of the thrust disc mounting plate 2. Under the action of the plastic film, the water pump thrust disc is adsorbed and fixed on the mounting plate through holes 5 by the surface tension of the clear water, and the polishing surface of the water pump thrust disc extends out of the mounting plate through holes 5. Then, put the thrust disc mounting plate 2, the plastic film and the adsorbed and fixed water pump thrust disc into the fixture base 1 together, and through the cooperation of the positioning bumps 3 of the fixture base 1 and the positioning notches 4 of the thrust disc mounting plate 2, the thrust disc mounting plate 2 is positioned and installed on the bottom surface of the fixture base 1. Finally, put them into the polishing equipment together to polish the water pump thrust disc; after polishing, put the thrust disc mounting 2 and the polished water pump thrust disc into water, and separate the plastic film, so that the water pump thrust disc loses the adsorption force and separates from the mounting plate through holes 5 respectively, realizing the functions of rapid loading and fixing and rapid separation of the thrust disc.

[0019] As Figures 1 - 3 shown in the figure, on the bottom surface of the fixture base 1, there is a base groove 6 for the thrust disc mounting plate 2 to be inserted, and the positioning bumps 3 are arranged at the edge position of the base groove 6; there are 4 positioning bumps 3 on the bottom surface of the fixture base 1, and they are evenly arranged on the bottom surface of the fixture base 1; there are 4 positioning notches 4 on the thrust disc mounting plate 2, and they are evenly arranged on the thrust disc mounting plate 2. This enables the thrust disc mounting plate 2 to be better positioned and installed on the bottom surface of the fixture base 1, and also prevents relative rotation between the thrust disc mounting plate 2 and the fixture base 1, which may affect the polishing effect.

[0020] As Figures 1 - 3 shown in the figure, the fixture base 1 is a circular fixture base; the thrust disc mounting plate 2 is a circular thrust disc mounting plate, which is convenient for the fixture base 1 to be driven to rotate for self-polishing in the polishing equipment.

[0021] As Figures 1 - 3 shown in the figure, there are 47 mounting plate through holes 5 on the thrust disc mounting plate 2; the thickness of the fixture base 1 is 2.5 mm; the diameter of the base groove 6 is 251 mm; the radius of the positioning bump 3 is 7.5 mm; the thickness of the thrust disc mounting plate 2 is 2.5 mm; the diameter of the thrust disc mounting plate 2 is 240 mm; the radius of the positioning notch 4 is 8 mm; the diameter of the mounting plate through hole 5 is 23 mm.

[0022] The above are only the preferred embodiments of the present utility model, and do not thus limit the patent scope of the present utility model. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, is included in the patent protection scope of the present utility model.
