Description

Technical Field

[0001] This utility model relates to the field of electronic water pump technology, specifically to a testing device for automotive electronic water pumps. Background Technology

[0002] In electric vehicles, water pumps are generally electronic water pumps. Electronic water pumps are mainly used for the circulating cooling of drive motors, electric components, and power batteries. Before leaving the factory, automotive electronic water pumps must undergo an airtightness test to prevent the "three leaks" problem of air leakage, water leakage, and oil leakage. Automotive electronic water pumps are mostly tested for airtightness using an airtightness detector, which typically consists of a housing, pipelines, inflation valve, deflation valve, and test head.

[0003] When testing an electronic water pump, it is usually necessary to fix the electronic water pump in the monitoring equipment.

[0004] Currently, automotive electronic testing equipment typically uses clamps to fix the device in place. However, such equipment cannot rotate after fixing, hindering observation and testing. Therefore, this invention proposes an automotive electronic water pump testing device to solve the aforementioned problems. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: an automotive electronic water pump testing device, which includes an outer frame 1 and a water pump 3. The electronic water pump 3 to be tested is placed in the outer frame 1 for testing. A buffer plate 4 is rotatably connected to the lower end of the outer frame 1, and an electric push rod 2 is fixedly connected to the upper end of the outer frame 1. The output end of the electric push rod 2 is interference-fitted with a bearing, and a fixing frame 5 is fixedly connected to the outer wall of the bearing. The fixing frame 5 can be moved up and down by the electric push rod 2. The buffer plate 4 is rotatably connected to the lower end of the outer frame 1, and the upper end of the water pump 3 is in close contact with the fixing frame 5. The fixing frame 5 can fix the water pump 3 vertically. The surface of the water pump 3 is in close contact with the limiting plate 13 and the pressure roller 8 in the fixing assembly. The lower end of the water pump 3 passes through the buffer plate 4 and the outer frame 1 in sequence, and the water pump 3 is in close contact with the buffer plate 4. At this time, the lower end of the water pump 3 is fixed.

[0021] Insert the water pump 3 into the hole opened in the buffer plate 4 and the outer frame 1, and then start the electric push rod 2. At this time, the fixing frame 5 moves down, and the upper and lower ends of the water pump 3 are squeezed and fixed by the fixing frame 5 and the buffer plate 4 to keep it stable.

[0022] The fixed cover 6 is fixedly connected to the fixed frame 5, and the screw 7 is threadedly connected to the fixed cover 6. When the screw 7 rotates, the fixed assembly begins to move. The end of the guide rod 14 away from the fixed plate 15 passes through the fixed cover 6 and is slidably connected to it. The sliding of the fixed assembly can be limited by the guide rod 14.

[0023] The fixing assembly includes: a lead screw 7, one end of which is fixedly connected to a rotating component 16, allowing the lead screw 7 to rotate; the other end of the lead screw 7 is rotatably connected to a connecting post 17, and the other end of the connecting post 17 is fixedly connected to a limiting plate 13, which moves the connecting post 17 when the lead screw 7 rotates; a fixing plate 15 is fixedly connected to the surface of the connecting post 17, and a guide rod 14 is fixedly connected to the surface of the fixing plate 15, preventing the fixing plate 15 from rotating; pressure rollers 8 are rotatably connected to both sides of the fixing plate 15 via rotating plates 9, and the two pressure rollers 8 are elastically connected, allowing the water pump 3 to be fixed; a rotating plate 9 is rotatably connected to the upper and lower ends of the two pressure rollers 8, allowing the position of the pressure rollers 8 to be fixed. The other end of the rotating plate 9 is rotatably connected to the fixed plate 15. A fixed post 10 is fixedly connected to the surface of the rotating plate 9. The other end of the fixed post 10 is fixedly connected to the nearest rotating plate 9. At this time, the two rotating plates 9 can move together through the fixed post 10. A second slide tube 12 is sleeved on the surface of the fixed post 10. A spring 18 is fixedly connected to the surface of the second slide tube 12. The other end of the spring 18 is fixedly connected to the first slide tube 11. When the rotating plate 9 rotates, the state of the spring 18 will change accordingly. The spring 18 is in a stretched state, which facilitates the reset of the pressure roller 8 and also allows the pressure roller 8 to exert pressure on the surface of the water pump 3, thereby fixing it. The first slide tube 11 is sleeved on the surface of the fixed post 10. When the state of the spring 18 changes, the first slide tube 11 will start to slide.

[0024] By rotating the rotating component 16, the lead screw 7 is driven to rotate, thereby causing the connecting column 17 to drive the limiting plate 13 to pass against the surface of the water pump 3 and press and fix it. During this process, the pressure rollers 8 on both sides of the fixing plate 15 begin to roll along the surface of the water pump 3, while the rotating plate 9 rotates to stretch the spring 18. At this time, the pressure rollers 8 provide auxiliary fixation for the water pump 3.

[0025] When the device is in operation, after the outer frame 1 is placed stably, the water pump 3 is installed. Then, the electric push rod 2 is started, and the water pump 3 is fixed vertically by the buffer plate 4. Then, the rotating part 16 is rotated to fix the water pump 3. At this time, when the water pump 3 needs to be tested, the water pump 3 can be rotated to facilitate the test.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
