The screw 5 drives the vertical block 6 to move downward, and the vertical block 6 drives the housing 7 to move downward. When the first rectangular plate 10 and the second rectangular plate 11 move to both sides of the water pump, start the cylinder 8 to drive the telescopic rod 9 to push the first rectangular plate 10 inward, and fix the top of the water pump through the first rectangular plate 10 and the second rectangular plate 11.
[0026] By placing the water pump above the base 1, moving the first rectangular plate 10 and the second rectangular plate 11 to both sides of the water pump through the servo motor 4, then starting the cylinder 8 to drive the cylinder 8 to push the first rectangular plate 10 inward, and fixing the water pump through the second rectangular plate 11. Compared with the traditional water pump maintenance device, the positioning device for water pump maintenance fixes the top of the water pump by the inward movement of the first rectangular plate 10 in cooperation with the second rectangular plate 11, so that water pumps of different specifications and sizes can be fixed, improving the working efficiency of the water pump maintenance device.
[0027] Among them, movable grooves 20 are evenly opened above the base 1. A second round rod 21 is fixedly installed inside the movable groove 20. A fixing block 22 is movably sleeved outside the second round rod 21. A return spring 23 is elastically installed between the inner side of the movable groove 20 and the inner side of the fixing block 22. The return spring 23 is movably connected to the outside of the second round rod 21.
[0028] Pull the fixing block 22 to make the fixing block 22 move outward inside the movable groove 20. The outward movement of the fixing block 22 squeezes the return spring 23 to cause the return spring 23 to deform. Then place the water pump between the fixing blocks 22 and release the fixing block 22. The return spring 23 releases elastic potential energy to push the fixing block 22, so that the fixing block 22 contracts inward to fix the bottom of the water pump, thus preventing the bottom of the water pump from shifting during maintenance.
[0029] By pulling the fixing block 22 to make the fixing block 22 move outward to squeeze the return spring 23 to cause the return spring 23 to deform, then place the water pump above the base 1, and the return spring 23 releases elastic potential energy to push the fixing block 22 to fix the bottom of the water pump. Compared with the traditional water pump maintenance device, the positioning device for water pump maintenance fixes the bottom of the water pump through the fixing block 22, preventing the bottom of the water pump from sliding and shifting during maintenance.

[0041] The inward movement of the first rectangular plate 10 drives the limiting block 19 to move inward around the limiting rod 24 inside the limiting groove 12, thereby limiting the first rectangular plate 10.
[0042] The working principle and usage process of the present utility model:
[0043] When the water pump needs to be positioned, first place the water pump above the base 1, then start the servo motor 4 to drive the screw 5 to rotate. The screw 5 drives the vertical block 6 to move downward, and the vertical block 6 drives the housing 7 to move downward. When the first rectangular plate 10 and the second rectangular plate 11 move to both sides of the water pump, start the cylinder 8 to drive the telescopic rod 9 to push the first rectangular plate 10 inward, and fix the top of the water pump through the first rectangular plate 10 and the second rectangular plate 11.
[0044] Pull the fixed block 22 to make the fixed block 22 move outward inside the movable slot 20.
