Description
Technical Field
[0001] This utility model relates to the technical field of water pump motor testing devices, and more specifically, to a water pump motor clamping fixture. Background Technology
[0002] As the core power unit of the fluid transport system, the performance and quality of the water pump motor are directly related to the operating efficiency and reliability of the entire system. In order to ensure that the water pump motor meets the design requirements, it is essential to conduct comprehensive testing on it from multiple dimensions, including vibration, noise, temperature rise, and insulation performance. Such tests are usually carried out on a special test bench and require clamping fixtures to press the water pump motor body into the working position.
[0003] Most common water pump motor clamping fixtures rely on clamping and limiting methods for fixation. These fixtures typically use clamping arms or rods that are basically in contact with the outer contour of the water pump motor to wrap around and apply pressure. However, we have found that in practical applications, especially when the water pump motor itself generates significant impact forces during operation, such as during start-up, stopping, and vibration testing, the constraint force provided by the clamping method is insufficient to completely resist continuous impacts. This can easily cause the water pump motor body to undergo slight displacement or even sliding within the fixture. This problem of unreliable fixation not only seriously interferes with the acquisition of dynamic parameters such as vibration and noise, leading to inaccurate test results, but may also cause safety hazards due to abnormal stress in extreme cases.
[0004] In view of this, we propose a water pump motor clamping fixture. Utility Model Content
[0005] Technical problems to be solved The purpose of this utility model is to provide a water pump motor clamping fixture to solve the problem mentioned in the background art that the fixing method of the traditional water pump motor clamping fixture needs to be improved. Technical solution
[0006] A water pump motor clamping fixture includes a water pump motor body, a mounting base fixedly connected to the water pump motor body, multiple mounting slots and a base formed on the mounting base, a turntable rotatably connected to the base, a connecting seat fixedly connected to the turntable, a first upright fixedly connected to the connecting seat, a second upright rotatably connected to the first upright, a mounting frame fixedly connected to the second upright, multiple limiting components fixedly connected to the connecting seat, and a locking component fixedly connected to the mounting frame. A limiting component, used to limit and press the pump motor body from the vertical direction; A locking assembly for detachably connecting the pump motor body to the connecting seat.
[0007] Preferably, a rotating block is fixedly connected to the bottom of the turntable, a rotating groove adapted to the size of the rotating block is provided on the base, a servo motor is fixedly connected to the base, a gear is fixedly connected to the output end of the servo motor, and a toothed ring meshing with the gear is fixedly connected to the turntable.
[0008] Preferably, the limiting component includes an electric push rod fixedly connected to the mounting frame and a connecting rod fixedly connected to the extended end of the electric push rod. Two first arc-shaped plates are fixedly connected to the connecting rod, and each of the two first arc-shaped plates is elastically provided with a second arc-shaped plate adapted to the size of the water pump motor body.
[0009] Preferably, a plurality of limiting rods are fixedly connected to the side of the second arc-shaped plate facing the first arc-shaped plate. The plurality of limiting rods are all disposed through the first arc-shaped plate, and a first spring is sleeved outside the plurality of limiting rods. The two ends of the first spring are fixedly connected to the opposite surfaces of the first arc-shaped plate and the second arc-shaped plate, respectively.
[0010] Preferably, the locking assembly includes a rod fixedly connected to the connecting seat and two locking blocks elastically disposed on the rod. The size of the rod is adapted to the size of the mounting groove, and the distance between the two locking blocks and the connecting seat is the same as the thickness of the mounting seat.
[0011] Preferably, the insert rod has a movable groove for sliding the locking block, and each of the two locking blocks is fixedly connected to a slider with a T-shaped cross section. The movable groove has a sliding groove adapted to the size of the slider, and the opposite surfaces of the two locking blocks are elastically connected by a second spring.
[0012] Preferably, the top end face of the locking block is inclined, so that when the insertion rod is inserted into the mounting groove, the wall of the mounting groove can squeeze the locking block and move it into the movable groove. Beneficial effects
[0013] Compared with existing technologies, the advantages of this utility model are: When the insertion rod of this utility model is inserted into the mounting slot, the locking block is squeezed and contracted under the inclined surface design. After passing through, it automatically pops out under the action of the second spring, firmly hooking the inner edge of the mounting slot. The mounting slot fits precisely. This structure can provide a hard limit when the water pump motor generates impact during operation, effectively preventing any slight displacement or loosening of the water pump motor relative to the connecting seat in the locking direction, and significantly improving the stability and accuracy of the testing process.
[0014] The rotating connection between the turntable and the base of this utility model, combined with the meshing of the servo motor drive gear and the turntable tooth ring, achieves precise and stable rotational adjustment in the horizontal plane. This allows the water pump motor to be easily adjusted in orientation without disassembly after being pressed, which greatly improves the testing efficiency and operational convenience for those who need to test from different angles or connect to different test stations.
[0015] The first arc-shaped plate of this utility model provides an overall support frame, while the second arc-shaped plate can adaptively conform to the curved contour of the water pump motor body. The elastic support structure composed of the limiting rod and the first spring not only ensures effective vertical limiting of the water pump motor to prevent jumping or overturning, but also provides flexible contact force. This not only adapts to water pump motor bodies of different specifications or with slightly different surfaces, but more importantly, avoids the risk of equipment damage caused by the rigid clamping of traditional clamping fixtures.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0021] Please see Figure 1-6 This utility model provides a technical solution: A water pump motor clamping fixture includes a water pump motor body 1, a mounting base 101 fixedly connected to the water pump motor body 1, multiple mounting slots 102 formed on the mounting base 101, and a base 11. A turntable 12 is rotatably connected to the base 11, a connecting seat 18 is fixedly connected to the turntable 12, a first upright 19 is fixedly connected to the connecting seat 18, a second upright 110 is rotatably connected to the first upright 19, a mounting frame 111 is fixedly connected to the second upright 110, multiple limiting components 2 are fixedly connected to the connecting seat 18, and a locking component 3 is fixedly connected to the mounting frame 111. The limiting components 2 are used to limit and clamp the water pump motor body from the vertical direction. 1; Locking assembly 3, which is used to detachably connect the water pump motor body 1 to the connecting seat 18. With this configuration, the turntable 12 is supported by the base 11 to achieve horizontal rotation, and the connecting seat 18 on the turntable 12 bears the installation of the water pump motor. It should be noted that, through the rotatable connection between the first upright 19 and the second upright 110, when installing or removing the water pump motor body 1, the mounting bracket 111 can be rotated upward or to the side by rotating the second upright 110, staggering the position to make enough operating space, so that the worker can easily place the mounting seat 101 of the water pump motor body 1 on the connecting seat 18 and align it with the locking assembly 3, or remove the body after it has been pressed.
[0022] The turntable 12 has a rotating block 13 fixedly connected to its bottom. A rotating groove 14 with a size matching the rotating block 13 is provided on the base 11. A servo motor 15 is fixedly connected to the base 11. A gear 16 is fixedly connected to the output end of the servo motor 15. A toothed ring 17 that meshes with the gear 16 is fixedly connected to the turntable 12. This configuration enables precise and controllable rotation driven by power. Specifically, the servo motor 15 provides stable rotational power, avoiding the laboriousness and inaccurate positioning problems of manual rotation. Secondly, the meshing of the gear 16 and the toothed ring 17 provides high-precision angle positioning capability, enabling the water pump motor body 1 to achieve a fixed detection angle. This ensures the stability and reliability of the turntable 12's rotation when carrying the water pump motor, providing a guarantee for comprehensive multi-angle detection.
[0023] Furthermore, the limiting component 2 includes an electric push rod 21 fixedly connected to the mounting bracket 111 and a connecting rod 22 fixedly connected to the extended end of the electric push rod 21. Two first arc-shaped plates 23 are fixedly connected to the connecting rod 22. Each of the two first arc-shaped plates 23 is elastically provided with a second arc-shaped plate 24 that matches the size of the water pump motor body 1. This arrangement achieves efficient and highly protective vertical clamping. First, the electric push rod 21 provides controllable power to achieve one-button lifting and lowering, which is convenient and reliable. Second, when the push rod is pressed down, the second arc-shaped plate 24 automatically adjusts the curvature and pressure distribution through its elastic structure, closely fitting the water pump motor body 1 to ensure full contact. In addition, the first spring 26, while applying the necessary constraint force, absorbs the small high-frequency vibrations that the body may generate during testing, avoiding rigid impact damage to the motor housing and improving test safety and equipment protection.
[0024] Specifically, multiple limiting rods 25 are fixedly connected to the side of the second arc-shaped plate 24 facing the first arc-shaped plate 23. The multiple limiting rods 25 are all set through the first arc-shaped plate 23, and a first spring 26 is sleeved on the outside of each of the multiple limiting rods 25. The two ends of the first spring 26 are fixedly connected to the opposite surfaces of the first arc-shaped plate 23 and the second arc-shaped plate 24, respectively. This arrangement can accurately control the elastic stroke and ensure the stability of the reset. The limiting rods 25 strictly constrain the movement trajectory of the second arc-shaped plate 24, preventing tilting due to lateral force during the pressing process. In addition, the arrangement of multiple springs can ensure that the motor housing is subjected to more uniform force and prevent excessive local stress. By fixing the two ends of the springs, it is ensured that the second arc-shaped plate 24 can be stably and reliably pulled back to its original position after unloading, keeping the mechanism in a clear state and facilitating repeated operation.
[0025] Secondly, the locking assembly 3 includes a rod 31 fixedly connected to the connecting seat 18 and two locking blocks elastically disposed on the rod 31. The size of the rod 31 is adapted to the size of the mounting groove 102, and the distance between the two locking blocks and the connecting seat 18 is the same as the thickness of the mounting seat 101. This arrangement enables a quick, secure, and detachable locking between the water pump motor body 1 and the connecting seat 18. In specific implementation, it is necessary to ensure that the outer diameter of the rod 31 is the same as the hole diameter of the mounting groove 102.
[0026] Furthermore, the insertion rod 31 has a movable groove 33 for sliding the locking block 32. Each locking block 32 is fixedly connected to a slider 34 with a T-shaped cross-section. The movable groove 33 has a sliding groove 35 that matches the size of the slider 34. The opposing surfaces of the two locking blocks 32 are elastically connected by a second spring 36. With this configuration, when the insertion rod 31 is inserted into the mounting groove 102, the top slope of the locking block is squeezed by the edge of the mounting groove 102, overcoming the tension of the second spring 36 and forcing the locking block to slide along the sliding groove 35 into the movable groove 33, thus achieving unobstructed insertion. Once the locking block has completely passed through the mounting groove 102, the second spring 36 immediately pushes the locking block outwards, locking it in place. The hook structure effectively resists the impact force generated during water pump motor testing.
[0027] Furthermore, the top end face of the locking block 32 is inclined, so that when the insertion rod 31 is inserted into the mounting groove 102, the wall of the mounting groove 102 can squeeze the locking block 32 and move it into the movable groove 33. The inclined surface can guide the locking block to retract smoothly into the movable groove 33, avoiding jamming during insertion and affecting the use of the device. This greatly improves the convenience of operation and the reliability of the tooling. In specific implementation, it is necessary to ensure that the locking block can be completely compressed into the mounting groove 102 when it passes through the mounting groove 102.
[0028] Working principle: Before installation, first Figure 2As shown, the mounting bracket 111 is rotated to the side to make room for operation. The water pump motor body 1 is placed on the connecting seat 18. After aligning the mounting groove 102 on the mounting seat 101 with the insertion rod 31 on the connecting seat 18, the insertion rod 31 is pushed into the mounting groove 102. During insertion, the inner wall of the mounting groove 102 presses against the inclined locking block 32 to retract it. After full insertion, the locking block 32 automatically pops out under the action of the spring and hooks onto the inner wall of the mounting groove 102 to achieve a firm lock in the horizontal direction. Then, the mounting bracket 111 is rotated back to the working position, and the electric push rod 21 is started to drive the clamping arm to press down, adaptively clamping the water pump motor body 1. When the detection angle needs to be adjusted, the servo motor 15 is started to drive the turntable 12 to rotate the entire assembly horizontally. After the detection is completed, the electric push rod 21 retracts into place, the mounting bracket 111 is rotated to make room, and then the locking block 32 is manually pressed back. The insertion rod 31 can then be pulled out and the water pump motor body 1 can be removed.
