Description

Technical Field

[0002] Sustainable development of energy and energy conservation and emission reduction are the common goals of the world's development. This goal has been promoting the development of new energy vehicles. Among them, automobile water pumps have also developed from mechanically driven water pumps to electrically driven water pumps, and electronic water pumps have been widely used in the market. Automobile electronic water pumps are also a type of water pump motor. When working, the motor cavity is filled with fluid, and the motor rotor is immersed in the fluid and rotates around the motor shaft. The presence of the fluid reduces the impact and friction between the rotor and the shaft. When there is no fluid in the motor, the rotor is in direct contact with the shaft, and it will wear and fail in a very short time, causing the motor to be scrapped. This working state is called idling.

[0003] The existing water pump idling test device has the following main drawbacks during use: it is impossible to fix water pumps of different sizes and shapes during testing, which causes the water pump to shake and fall over easily during the test. At the same time, it lacks the function of detecting the vibration amplitude and noise level when the water pump is idling, and the test data is less comprehensive. Therefore, there is room for improvement. Utility Model Content

[0028] The bottom plate 110 is used to place the water pump, the bracket 120 is used to install the detection member 130, and the detection member 130 is used to drive the water pump to idle, so as to facilitate the test. The detection member 130 includes a first electric telescopic rod 131 fixed on the bracket 120, a fixing frame 132 fixed on the end of the first electric telescopic rod 131, and a driving motor 133 installed on the fixing frame 132. The fixing frame 132 is used to connect the first electric telescopic rod 131 and the driving motor 133 together to form a whole, so that when the first electric telescopic rod 131 is extended or retracted, it can synchronously drive the driving motor 133 to move up and down, and the driving motor 133 is used to drive the hand water pump to idle.

[0029] The elastic legs 140 are used to support the bottom plate 110 and facilitate vibration of the bottom plate 110 , and include a base 141 disposed below the bottom plate 110 and a first spring 142 symmetrically fixed to the top of the base 141 and fixedly connected to the bottom plate 110 .

[0030] When the detection member 130 moves downward to drive the water pump to idle, the vibration generated by the idling of the water pump drives the base plate 110 to vibrate, and the vibration sensor 150 monitors and records the vibration data. At the same time, the decibel meter 160 monitors and records the decibel of noise generated when the water pump is idling, which can effectively test the vibration data and noise data of the water pump in the idling state.

The driving member 210 includes a threaded rod 211 rotatably mounted on the inner wall of the groove 111, a round rod 212 having one end fixed to the end of the threaded rod 211 and the other end extending out of the bottom plate 110, and a knob 213 fixed to the end of the round rod 212. At the same time, the positioning block 220 includes a threaded sleeve 221 sleeved on the threaded rod 211 and extending out of the groove 111, and a baffle 222 fixed to the top of the threaded sleeve 221. The threaded rod 211 and the threaded sleeve 221 are meshed with each other, so that when the threaded rod 211 rotates, the threaded sleeve 221 is driven to move, and the movement of the threaded sleeve 221 drives the baffle 222 to move. The baffle 222 is used to position the water pump, so that when the water pump is placed on the bottom plate 110, the impeller of the water pump and the driving motor 133 are located on the same vertical line. The knob 213 is used to rotate the threaded rod 211, thereby increasing the convenience of use.

[0033] The second electric telescopic rod 230 is used to install the clamp block 240 and drive the clamp block 240 to move, so as to clamp and fix the water pump. The elastic rod 250 includes a support rod 251 at one end movably arranged in the inner cavity of the clamp block 240 and the other end extending out of the clamp block 240, and a second spring 252 connecting the end of the support rod 251 and the inner wall of the clamp block 240.

At the same time, with this arrangement, when the clamp block 240 is close to the water pump, the end of the support rod 251 can automatically adjust and retract along the outer edge shape of the water pump, so as to adapt to water pumps of different shapes and sizes.

[0034] The working principle and use process of the utility model are as follows: during the test, the knob 213 is turned to drive the threaded rod 211 to rotate through the round rod 212, the threaded rod 211 rotates to drive the threaded sleeve 221 to move, the threaded sleeve 221 moves to drive the baffle 222 to move, and the baffle 222 is moved to the specified position, so that the impeller in the water pump and the shaft of the driving motor 133 are located on the same vertical line, the water pump is placed on the bottom plate 110, and one side of the water pump is close to the baffle 222, at this time the second electric telescopic rod 230 is started, driving the clamping blocks 240 on both sides to move towards each other, clamping and fixing the water pump, and at the same time due to the elastic With the setting of the elastic rod 250, the end of the support rod 251191 can be retracted along the outer edge shape of the water pump, so as to adapt to water pumps of different shapes and sizes. After the clamping is completed, the first electric telescopic rod 131 is started, and the driving motor 133 is driven to move downward and inserted into the water pump through the fixed frame 132. Then the driving motor 133 is started to drive the water pump to idle. The vibration sensor 150 monitors and records the vibration data of the water pump when it is idling.
