[0021] Figure 1-4This invention illustrates a positioning structure for grinding the inner wall of a motor pump housing according to an embodiment of the present invention. It includes a worktable 2 disposed at the bottom of a grinding machine 1; the grinding machine 1 is fixedly mounted on the top of the worktable 2; a servo motor and a grinding rod are disposed on the surface of the grinding machine 1; the output shaft of the servo motor is fixedly connected to the grinding rod of the grinding machine 1; two symmetrical slots 19 are fixedly connected to the surface of the grinding machine 1; two T-shaped clips 18 are fixedly connected to both sides of a collection box 17; a handle is fixedly connected to the surface of the collection box 17; the clips 18 are adapted to the slots 19; and a [missing information - likely a design feature] is provided on the top of the worktable 2. The slot 16, through the cooperation of the collection box 17, the retaining strip 18, and the retaining groove 19, allows the retaining strip 18 to be inserted into the inner cavity of the retaining groove 19, thus limiting the collection box 17 to the bottom of the slot 16. After the grinding rod of the grinder 1 finishes grinding the inner wall of the motor pump housing, the grinding debris is swept into the collection box 17 through the slot 16, facilitating the cleaning and collection of the grinding debris. The collection box 17 is provided at the bottom of the slot 16. Two symmetrical fixing frames 3 are fixedly connected to the top of the worktable 2. One of the fixing frames 3 has a threaded rod 4 rotatably connected to its surface, and the other fixing frame 3 has a fixed surface. A limit rod 5 is connected to the inner cavity of the fixed frame 3, which is equipped with a slider 6. A threaded rod 4 passes through the slider 6 and is threadedly connected to it. The limit rod 5 passes through the slider 6 and is slidably connected to it. A motor 7 is fixedly installed on the top of one of the fixed frames 3. The output shaft of the motor 7 passes through the fixed frame 3 and is fixedly connected to the threaded rod 4. A limit plate 8 is fixedly connected to the back of the two sliders 6. A threaded rod 9 is rotatably connected to the surface of the limit plate 8. A motor 10 is fixedly installed on the surface of the limit plate 8. The output shaft of the motor 10 passes through the limit plate 8 and is threadedly connected to the threaded rod 4. Rod 2 9 is fixedly connected. The inner cavity of the limiting plate 8 is provided with a movable plate 11. Threaded rod 2 9 passes through the movable plate 11 and is threadedly connected to the movable plate 11. Two symmetrical fixing blocks 12 are fixedly connected to the bottom of the movable plate 11. Two symmetrical clamps 13 are provided between the two fixing blocks 12.

[0022] Working Principle: When using this invention, the user places the motor pump housing between two clamps 13. At this time, the grinding rod of the grinder 1 is located in the inner cavity of the motor pump housing. The output shaft of motor 3 15 drives the bidirectional lead screw 14 to rotate, causing the bidirectional lead screw 14 to drive the two clamps 13 to move relative to each other. This allows the two clamps 13 to clamp and position the motor pump housing. Then, the output shaft of motor 1 7 drives the threaded rod 4 to rotate, causing the threaded rod 4 to move through the limit rod 5, which in turn moves the slider 6. The slider 6 then moves the limit plate 8. Finally, the output shaft of motor 2 10 drives the threaded rod 9 to rotate, causing the threaded rod 9 to move the moving plate 11. The moving plate 11 is then clamped by the clamps 13. The grinding wheel of the grinding machine 1 moves the motor pump housing, causing the grinding rod to come into contact with the inner wall of the motor pump housing. Then, the output shaft of the servo motor of the grinding machine 1 drives the grinding rod to grind the inner wall of the motor pump housing. This achieves the purpose of automatically clamping, positioning and moving the motor pump housing, thereby reducing quality problems caused by differences in manual operation. Through the coordinated use of the slot 16, the collection box 17, the locking strip 18 and the locking groove 19, the locking strip 18 is inserted into the inner cavity of the locking groove 19, so that the collection box 17 is limited to the bottom of the slot 16. After the grinding wheel of the grinding machine 1 finishes grinding the inner wall of the motor pump housing, the grinding debris is swept into the collection box 17 through the slot 16, which facilitates the cleaning and collection of the grinding debris.

[0023] In summary, this positioning structure for grinding the inner wall of the motor pump housing achieves automatic clamping, positioning, and movement of the motor pump housing by placing it between two clamps 13. The output shaft of motor three 15 drives the bidirectional lead screw 14 to rotate, causing the two clamps 13 to clamp and position the housing. Then, the output shaft of motor one 7 drives the threaded rod one 4 to rotate, causing the threaded rod one 4 to move the slider 6, which in turn moves the limiting plate 8. Finally, the output shaft of motor two 10 drives the threaded rod two 9 to rotate, causing the threaded rod two 9 to move the moving plate 11. The grinding rod of the grinding machine 1 then grinds the inner wall of the housing. This achieves the goal of automatically clamping, positioning, and moving the motor pump housing, thereby reducing quality problems caused by differences in manual operation.
