[0002] A pump is a machine that uses power to transport liquids, gases, or powders to another location. Common types include water pumps, oil pumps, and air pumps. Water pumps are often used for pumping and supplying water, while oil pumps can transport oils. Air pumps are typically used for transporting gases or increasing pressure differences. Common water pumps usually consist of a pump body, shaft, impeller, bearings, sealing structure, and power source.

[0003] In the process of machining the pump body, the traditional fixing method often uses clamps to hold and fix the pump body on both sides. As a result, the machining of the outer wall of the pump body is affected by the clamps, making it inconvenient to machine the outer wall of the pump body. In order to solve the above problems, there is an urgent need for a fixing device for machining pump body parts. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that using a clamp to fix the outer wall of the pump body affects the processing of the outer wall of the pump body when clamping and fixing it, and to propose a fixing device for processing pump body parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fixing device for processing pump body parts, including a mounting base, a fixing component on the top surface of the mounting base, and limiting components on both sides of the fixing component;

[0006] The fixing assembly includes a first gear, a second gear meshing with the outer side of the first gear, a connecting shaft fixedly mounted on the top surface of the second gear, a push block fixedly mounted on the outer wall of the connecting shaft, a hinge seat fixedly mounted on one side of the push block, a pressure plate hinged to the hinge seat, a first spring fixedly mounted on one side of the pressure plate, a lever fixedly mounted on the bottom end of the first gear, a moving block slidably mounted on the lever through a groove opened on its surface, a plug rod fixedly mounted on one side of the moving block, and a second spring fixedly mounted on the other side of the moving block.

[0013] As a further description of the above technical solution:

[0014] The limiting component includes a third gear, which is located inside the mounting base and meshes with a second gear on one side. A threaded rod is fixedly mounted on the top surface of the third gear.

[0022] 1. In this utility model, by providing a fixing component inside, the pump body can be fastened onto the mounting base during pump body processing, with the push block located in the cavity inside the pump body. Rotating the lever drives the first gear to rotate, and the second gear drives the push block to rotate, allowing the pressure plate on one side of the push block to contact and compress the inner wall of the pump body, thus fixing the pump body. Furthermore, during the contact between the pressure plate and the inner wall of the pump body, a first spring ensures that the pressure plate remains in contact with the inner wall, avoiding the impact of unevenness in the inner wall of the pump body and further ensuring the stability of the fixation.

[0023] 2. In this utility model, by setting a limiting component inside, the design enables the second gear to drive the third gear to rotate during the pump body manufacturing process, thereby driving the threaded rod to rotate and causing the threaded sleeve and sliding frame to move downward. This allows the sliding frame to press and fix the edge of the pump body end face, further ensuring the stability of the pump body during processing and preventing the pump body from shifting during processing.

[0031] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] In its specific implementation, such as Figures 1-5 This utility model provides a technical solution: a fixing device for processing pump body parts, including a mounting base 1, a fixing component 2 on the top surface of the mounting base 1, and limiting components 3 on both sides of the fixing component 2;

[0033] The fixing assembly 2 includes a first gear 21, a second gear 27 meshing with the outer side of the first gear 21, a connecting shaft 25 fixedly mounted on the top surface of the second gear 27, a push block 26 fixedly mounted on the outer wall of the connecting shaft 25, a hinge seat 24 fixedly mounted on one side of the push block 26, a pressure plate 22 hinged to the hinge seat 24, a first spring 23 fixedly mounted on one side of the pressure plate 22, a lever 28 fixedly mounted on the bottom end of the first gear 21, and a moving block 210 slidably mounted on the lever 28 through a groove on its surface. One side of the moving block 210 is fixed... A plug rod 29 is installed, and a second spring 211 is fixedly installed on the other side of the moving block 210. The other end of the second spring 211 is fixedly connected to the lever 28. The lever 28 is slidably connected to the mounting base 1 through a slot opened in the mounting base 1. The first gear 21 is located inside the mounting base 1. The connecting shaft 25 is rotatably connected to the mounting base 1 through a slot opened on the top surface of the mounting base 1. One end of the first spring 23 is fixedly connected to the push block 26. The push block 26 is located on the top surface of the mounting base 1. The plug rod 29 is slidably connected to the mounting base 1 through a slot opened on the outer wall of the mounting base 1.

[0034] During the processing of the pump body, the pump body is fastened to the surface of the mounting base 1, and the push block 26 is located in the cavity inside the pump body. By pulling the moving block 210, the insertion rod 29 is separated from the insertion hole on the outside of the mounting base 1, thereby pushing the lever 28 to drive the first gear 21 to rotate. The rotation of the first gear 21 drives the second gear 27 to rotate, thereby driving the push block 26 to rotate. The pressure plate 22 on one side of the push block 26 comes into contact with the inner wall of the pump body. The pump body is fixed by the pressure plate 22 pressing against the inner wall of the pump body. The insertion rod 29 is then reinserted into the slot on the outer wall of the mounting base 1 to limit the first gear 21.

[0035] like Figure 4 As shown, the limiting component 3 includes a third gear 37, which is located inside the mounting base 1 and meshes with a second gear 27 on one side. A threaded rod 36 is fixedly installed on the top surface of the third gear 37. The threaded rod 36 is rotatably connected to the mounting base 1 through a through hole on the top surface of the mounting base 1. A threaded sleeve 33 is threadedly connected to the outer wall of the threaded rod 36. Fixed frames 34 are fixedly installed on both sides of the threaded sleeve 33. A limiting rod 35 is slidably installed in the fixed frame 34 through a through hole. The bottom end of the limiting rod 35 is fixedly connected to the mounting base 1. A sliding frame 31 is slidably installed in the fixed frame 34 through a groove. A pin 32 is slidably installed in the sliding frame 31 through a groove. The pin 32 is slidably connected to the fixed frame 34 through a through hole.

[0036] When fixing the pump body, first push the sliding frame 31 so that one end is close to the pump body and moves it to a suitable position. Then, fix the sliding frame 31 to the fixed frame 34 through the pin 32. When the lever 28 drives the first gear 21 to rotate, the second gear 27 drives the third gear 37 to rotate, thereby driving the threaded rod 36 to rotate and driving the threaded sleeve 33 to move downward. This causes the sliding frame 31 to move downward and make the bottom end of the sliding frame 31 contact the edge of the pump body end face. At the same time, a pad can be added to ensure that the sliding frame 31 can press against the edge.

[0037] Working principle: During the processing of the pump body, the pump body is fastened onto the surface of the mounting base 1, and the push block 26 is located in the cavity inside the pump body. Then, the sliding frame 31 is pushed so that one end is close to the pump body and moves to a suitable position. The sliding frame 31 is then fixed to the fixed frame 34 by the pin 32. By pulling the moving block 210, the insertion rod 29 is separated from the insertion hole on the outside of the mounting base 1, thereby pushing the lever 28 to drive the first gear 21 to rotate. The rotation of the first gear 21 drives the second gear 27 to rotate, thereby driving the push block 26 to rotate. One side of the pressure plate 22 contacts the inner wall of the pump body, thereby fixing the pump body by squeezing the inner wall of the pump body with the pressure plate 22, and re-inserting the insertion rod 29 into the slot on the outer wall of the mounting base 1 to limit the first gear 21. During the rotation of the first gear 21, the second gear 27 can drive the third gear 37 to rotate, thereby driving the threaded rod 36 to rotate, and driving the threaded sleeve 33 to move downward, thereby driving the sliding frame 31 to move downward, and at the same time, the bottom end of the sliding frame 31 contacts the edge of the pump body end face. At the same time, the sliding frame 31 can be pressed tightly against the edge by adding a pad.

[0038] 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.
