[0004] In the aforementioned patent, after the pump body is placed inside the base, starting the second motor can drive the limiting block to approach the fixed limiting rod, thereby fixing the pump body and improving the stability of the pump body during the grinding process. However, both the limiting block and the fixed limiting rod are in contact with the side surface of the pump body. When the side surface of the pump body needs to be ground, the limiting block and the fixed limiting rod will hinder the grinding process, which may affect the processing quality of the pump body grinding.

[0005] Therefore, this utility model provides a grinding device for surface processing of submersible pumps to solve the above-mentioned problems. Utility Model Content

[0017] 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.

[0018] This utility model provides a grinding device for surface processing of submersible pumps, such as... Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, it includes a base plate 1, a working plate 2 fixedly connected to the top of the base plate 1, a rotating groove 3 opened on the top of the working plate 2, a rotating plate 4 rotatably connected inside the rotating groove 3, a mounting shell 5 fixedly connected to the top of the rotating plate 4, a mounting cylinder 6 fixedly connected to the side surface of the mounting shell 5, the inner cavity of the mounting cylinder 6 communicating with the inner cavity of the mounting shell 5, and a fixing mechanism is provided inside the mounting cylinder 6 and the mounting shell 5.

[0019] The fixing mechanism includes a movable rod 9, which is slidably connected inside the mounting cylinder 6. One end of the movable rod 9 extends to the outside of the mounting cylinder 6 and is fixedly connected to a fixing block 11. A rubber pad 12 is fixedly connected to the side of the fixing block 11 away from the movable rod 9. The other end of the movable rod 9 extends into the inside of the mounting shell 5 and is fixedly connected to a second step block 10.

[0020] The fixing mechanism also includes a first step block 8, which is located inside the mounting shell 5. An electric push rod 7 is fixedly connected to the bottom inner wall of the mounting shell 5, and the movable end of the electric push rod 7 is fixedly connected to the bottom of the first step block 8.

[0021] A first limiting ring 14 is fixedly connected to the side surface of the moving rod 9, and a spring 13 is sleeved on the side surface of the moving rod 9. One end of the spring 13 is fixedly connected to the inner wall of one side of the mounting cylinder 6, and the other end of the spring 13 is fixedly connected to one side of the first limiting ring 14.

[0022] When using this grinding device, the grinder can be installed on top of the work plate 2. The grinder is a common existing device, so it is not shown in the figure and will not be described in detail here. When grinding the side surface of the pump body, the pump body needs to be placed on the mounting cylinder 6 and the mounting shell 5. Then, the electric push rod 7 is activated. When the electric push rod 7 moves the first step block 8 upward, the inclined surface of the first step block 8 will press against the inclined surface of the second step block 10. After being pressed, the second step block 10 will push the moving rod 9 to move. When the moving rod 9 moves, it can drive the fixed block 11 and the rubber pad 1. 2. When the rubber pad 12 is tightly attached to the inner wall of the pump body, the pump body is fixed. The rubber pad 12 increases the friction between the fixing block 11 and the pump body, which improves the stability of the pump body during the grinding process. In addition, when the moving rod 9 moves, the first limiting ring 14 will compress the spring 13. When the electric push rod 7 drives the first step block 8 to reset, the spring 13 will release the pressure and drive the moving rod 9, the fixing block 11 and the rubber pad 12 to reset, so that the staff can easily remove the pump body after grinding.

[0023] Furthermore, in order for the rotating plate 4 to rotate with the pump body, such as... Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, a first rotating shaft 15 is fixedly connected to the top of the base plate 1, a gear 16 is rotatably connected to the side surface of the first rotating shaft 15, a connecting strip 17 is fixedly connected to the top of the gear 16, and the top end of the connecting strip 17 is fixedly connected to the bottom of the rotating plate 4.

[0024] A motor 19 is fixedly connected to the bottom of the working plate 2. A gear 20 is fixedly connected to the output end of the motor 19. The gear 20 meshes with the gear plate 16. A second limiting ring 18 is fixedly connected to the side surface of the rotating plate 4. The bottom of the second limiting ring 18 is in contact with the top of the working plate 2.

[0025] An auxiliary frame 21 is fixedly connected to the bottom of the working plate 2. A second rotating shaft is fixedly connected inside the auxiliary frame 21. A roller 22 is rotatably connected to the side surface of the second rotating shaft. The side surface of the roller 22 is in contact with the side surface of the rotating plate 4.

[0026] When the motor 19 is started, its output can directly drive the gear 20 to rotate. When the gear 20 rotates, it can drive the gear disk 16 to rotate, which in turn causes the rotating plate 4 to rotate with the pump body. This facilitates the grinding machine to grind the side surface of the pump body. The setting of the second limiting ring 18 reduces the possibility of the rotating plate 4 falling off the rotating groove 3. When the rotating plate 4 rotates, the roller 22 will also rotate due to friction to assist the rotating plate 4 in rotating. This effectively reduces the friction force when the rotating plate 4 rotates and improves the smoothness of the rotating plate 4.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
