[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figures 1-3 This utility model provides a technical solution: a water pump impeller grinding device, including a working frame 1, a support leg 2 fixedly installed at the bottom of the working frame 1, a positioning mechanism 3 for positioning the impeller fixedly installed at the top of the working frame 1, an auxiliary pressing mechanism 4 for pressing and positioning the impeller at the top of the working frame 1, two sets of position adjustment mechanisms 5 fixedly installed at the top of the working frame 1, a first grinding mechanism 6 and a second grinding mechanism 7 respectively set on the two sets of position adjustment mechanisms 5 in the "X" axis direction and the "Y" axis direction, and a height adjustment mechanism 8 for driving the position adjustment mechanism 5 to move up and down is fixedly installed on the working frame 1.
[0018] The positioning mechanism 3 can position and rotate the water pump impeller, while the auxiliary clamping mechanism 4 can clamp and position the top of the water pump impeller. The first grinding mechanism 6 and the second grinding mechanism 7 are set as the "X" axis and "Y" axis, respectively, which allows for all-round grinding of the impeller. The position adjustment mechanism 5 can drive the first grinding mechanism 6 and the second grinding mechanism 7 to contact the outer wall of the impeller to prevent grinding dead corners. The height adjustment mechanism 8 can drive the first grinding mechanism 6 and the second grinding mechanism 7 to move up and down, thus moving up and down along the outside of the impeller to complete all-round grinding.
[0019] Please see Figure 1 and Figure 2The positioning mechanism 3 includes a drive motor 9, a rotating shaft 10, and a bottom positioning plate 11. The drive motor 9 is fixedly installed on the top of the work frame 1. The output end of the drive motor 9 is fixedly connected to the rotating shaft 10. The bottom positioning plate 11 is fixedly installed on the top of the rotating shaft 10. The auxiliary pressing mechanism 4 includes a first support frame 12, a first drive cylinder 13, a rotating seat 14, a rotating shaft 15, and a pressing plate 16. The first support frame 12 is fixedly installed on the top of the work frame 1. The first drive cylinder 13 is fixedly installed on the first support frame 12. The output end of the first drive cylinder 13 is fixedly connected to the rotating seat 14. The rotating shaft 15 is rotatably connected inside the rotating seat 14. The pressing plate 16 is fixedly connected to the bottom of the rotating shaft 15.
[0020] When the impeller needs to be polished, the impeller is placed outside the bottom positioning plate 11. Then, the first drive cylinder 13 drives the rotating seat 14 and the pressing plate 16 to descend and contact the limit position at the top of the water pump. Then, the drive motor 9 drives the rotating shaft 10 and the bottom positioning plate 11 to rotate. The pressing plate 16 contacts the top of the impeller and is rotatably connected to the rotating seat 14 through the rotating shaft 15, so that the impeller can be rotated and polished during polishing.
[0021] Please see Figure 1 and Figure 2 The position adjustment mechanism 5 includes a fixed base 17, a slide rail 18, a slider 19, a movable plate 20, a threaded rod 21, and a first drive motor 22. Two sets of slide rails 18 are fixedly installed on the top of the fixed base 17. The movable plate 20 is slidably connected to the slide rails 18 via the slider 19. The threaded rod 21 is rotatably connected to the fixed base 17. The first drive motor 22 is fixedly installed on one side of the fixed base 17. The output end of the first drive motor 22 is fixedly connected to the threaded rod 21. A threaded sleeve 23 is threadedly connected to the outside of the threaded rod 21. The top of the threaded sleeve 23 is fixedly connected to the movable plate 20. The first grinding mechanism 6 and the second grinding mechanism 7 have the same structure and both include a second support frame 24, a second drive motor 25, and a grinding disc 26. The second support frame 24 is fixedly installed on the top of the movable plate 20. The second drive motor 25 is fixedly installed on the second support frame 24. The output end of the second drive motor 25 is fixedly connected to the grinding disc 26.
[0022] When the positions of the first grinding mechanism 6 and the second grinding mechanism 7 need to be adjusted, the first drive motor 22 drives the threaded rod 21 to rotate. Then the threaded rod 21 drives the threaded sleeve 23 and the moving plate 20 to move. When the moving plate 20 moves, it can be limited by the slide rail 18 and the slider 19 to prevent the moving plate 20 from shifting position. After the position movement is completed, the grinding disc 26 set in the "X" axis and "Y" axis direction is in contact with the outside of the impeller. Then the second drive motor 25 can drive the grinding disc 26 to rotate, thereby completing the all-round grinding process of the impeller.
[0023] Please see Figure 1 and Figure 3 The height adjustment mechanism 8 includes a limiting sleeve 27, a telescopic rod 28, and a connecting plate 29. Multiple sets of limiting sleeves 27 are fixedly installed at the bottom of the work frame 1. The telescopic rod 28 is slidably connected inside the limiting sleeve 27. The top of the telescopic rod 28 is fixedly connected to the fixed base 17. The bottom of the telescopic rod 28 is fixedly connected to the connecting plate 29. A second drive cylinder 30 is fixedly installed on the connecting plate 29. The output end of the second drive cylinder 30 is fixedly connected to the work frame 1.
[0024] When the impeller is rotating during grinding, the output end of the second drive cylinder 30 is fixedly connected to the bottom of the work frame 1. Then, when the second drive cylinder 30 operates, the connecting plate 29 and the telescopic rod 28 can move along the inside of the limiting sleeve 27. In this way, the first grinding mechanism 6 and the second grinding mechanism 7 can be driven to move up and down along the outside of the impeller, thereby completing the all-round grinding of the impeller.
[0025] In use, firstly, the positioning mechanism 3 positions and rotates the water pump impeller, while the auxiliary clamping mechanism 4 clamps and positions the top of the water pump impeller. The first grinding mechanism 6 and the second grinding mechanism 7 are positioned along the "X" and "Y" axes, respectively, allowing for all-around grinding of the impeller. Subsequently, the position adjustment mechanism 5 drives the first grinding mechanism 6 and the second grinding mechanism 7 to contact the outer wall of the impeller, preventing grinding dead angles. The height adjustment mechanism 8 drives the first grinding mechanism 6 and the second grinding mechanism 7 to move up and down, allowing for all-around grinding along the outside of the impeller. When grinding the impeller is required, it is placed outside the bottom positioning plate 11. Then, the first drive cylinder 13 lowers the rotating seat 14 and the clamping plate 16, bringing them to a limit position and clamping them at the top of the water pump. The drive motor 9 then rotates the rotating shaft 10 and the bottom positioning plate 11, causing the clamping plate 16 to contact the top of the impeller and rotate via the rotating shaft 15 and rotating seat 14, thus allowing the impeller to be ground. During grinding, the wheel can rotate. When the positions of the first grinding mechanism 6 and the second grinding mechanism 7 need to be adjusted, the first drive motor 22 drives the threaded rod 21 to rotate. Then, the threaded rod 21 drives the threaded sleeve 23 and the moving plate 20 to move. The moving plate 20 can be limited by the slide rail 18 and the slider 19 to prevent the moving plate 20 from shifting position. After the position is moved, the grinding disc 26 set in the "X" axis and "Y" axis direction is in contact with the outside of the impeller. Then, the second drive motor 25 can drive the grinding disc 26 to rotate, thereby completing the all-round grinding of the impeller. When the impeller is grinding and rotating, the output end of the second drive cylinder 30 is fixedly connected to the bottom of the work frame 1. Then, the second drive cylinder 30 operates, which can make the connecting plate 29 and the telescopic rod 28 move along the inside of the limiting sleeve 27. In this way, the first grinding mechanism 6 and the second grinding mechanism 7 can be driven to move up and down along the outside of the impeller, thereby completing the all-round grinding of the impeller.
