[0039] Example:

[0040] This embodiment provides an electronic water pump vibration measuring device, which is used to solve the technical problem of low vibration measurement efficiency of electronic water pump vibration measuring devices in the prior art. The electronic water pump vibration measuring device includes a bracket 1, a rope 2, a mounting plate 3, a tray 4, a clamping assembly 5, a triaxial vibration sensor 6, and a controller, wherein:

[0041] The bracket 1 includes a bottom plate, a top plate and a connecting plate. The bottom plate and the top plate are arranged at intervals along the first direction, that is, the top plate is located directly above the bottom plate, and the bottom plate and the top plate are arranged parallel to each other. The two ends of the connecting plate can be detachably installed on the bottom plate and the top plate respectively, and the connecting plate and the bottom plate are arranged perpendicular to each other.

[0042] One end of the rope 2 is connected to the top of the bracket 1, that is, one end of the rope 2 is connected to the top plate.

[0043] The mounting plate 3 is connected to the other end of the rope 2. An opening for accommodating the detection electronic water pump is provided in the middle of the mounting plate 3, and the opening runs through the front end of the mounting plate 3. In this way, the setting of the opening makes it easier to place the electronic water pump to be detected.

[0044] The tray 4 is mounted on the bracket 1 and can be moved along a first direction, that is, the tray 4 can move up and down. The tray 4 is used to place the electronic water pump.

[0045] The clamping assembly 5 is installed on the mounting plate 3. The clamping assembly 5 is used to clamp the electronic water pump. In this way, the setting of the clamping assembly 5 facilitates clamping the electronic water pump to be tested, thereby preventing the electronic water pump from tipping over or falling during the testing process.

[0046] The three-axis vibration sensor 6 is installed on the mounting plate 3. The three-axis vibration sensor 6 can measure vibration conditions in three mutually perpendicular directions at the same time, can capture the rotation characteristics of the object more comprehensively, and provide more accurate vibration data. It has high-precision measurement capabilities and usually only requires one installation point during installation, which reduces installation complexity and wiring work, saving time and cost.

[0047] The controller is electrically connected to the tray 4, the clamping assembly 5 and the three-axis vibration sensor 6. In this way, through the setting of the controller, it is easier to control the up and down movement of the tray 4 and to control the on and off of the clamping assembly 5 and the three-axis vibration sensor 6.

[0048] Through the above structure, when the vibration of the electronic water pump needs to be measured, the electronic water pump is first placed on the tray 4 and positioned in the opening of the mounting plate 3. The clamping assembly 5 is then driven to clamp the electronic water pump. After clamping, the tray 4 is driven to move away from the electronic water pump so that the tray 4 is separated from the electronic water pump. The power supply of the electronic water pump is then connected, and the electronic water pump starts to run and vibrate, and the clamping assembly 5 connected to the electronic water pump vibrates synchronously. The clamping assembly 5 is arranged on the mounting plate 3, and the mounting plate 3 is flexibly connected to the bracket 1 through the rope 2. Therefore, the vibration of the clamping assembly 5 is transmitted to the three-axis vibration sensor 6 through the mounting plate 3. The three-axis vibration sensor 6 will simultaneously collect vibration accelerations in three mutually perpendicular directions. The controller detects the vibration of the electronic water pump and converts it into an electrical signal to transmit to the controller, and the vibration analysis software determines whether the vibration value meets the technical requirements, thereby achieving the purpose of detecting the electronic water pump. In this way, the flexibly connected mounting plate 3 reduces the probability of the mounting plate 3 being disturbed during vibration. After the test is completed, the controller controls the tray 4 to move toward the direction close to the electronic water pump until the tray 4 supports the electronic water pump and drives the clamping assembly 5 to release the electronic water pump. Finally, the electronic water pump that has completed the test is taken out and replaced with the electronic water pump to be tested. In this way, the cooperation between the controller, the clamping assembly 5 and the tray 4 makes it easier to control the tray 4 and the clamping assembly 5, so that the electronic water pump vibration measuring device provided by the utility model is easier to operate, thereby improving the vibration measurement efficiency.

[0049] An optional implementation of this embodiment is as follows: the clamping assembly 5 includes a clamping claw 51 and a driving member 52, wherein:

In this way, through the setting of the two clamping claws 51, when it is necessary to clamp the electronic water pump to be tested, it is only necessary to move the two clamping claws 51 in a direction toward each other; when it is necessary to release the electronic water pump to be tested, it is only necessary to move the two clamping claws 51 in a direction away from each other.

[0051] Optionally, the opposite sides of the two claws 51 are arc-shaped. In this way, the contact area between the claws 51 and the electronic water pump is increased by setting the arc-shaped contact surface, thereby increasing the friction between the claws 51 and the electronic water pump, and making the electronic water pump clamped more firmly.

[0052] There are two driving members 52 , and the two driving members 52 are respectively used to drive the two claws 51 to move along the second direction. In this way, the arrangement of the driving members 52 makes it easier to drive the two claws 51 to move on the mounting plate 3 .

In this way, through the arrangement of the four ropes 2, the mounting plate 3 is installed more firmly, and the four ropes 2 are symmetrically arranged, so that the force on the ropes 2 is more uniform.

[0059] An optional implementation of this embodiment is as follows: it also includes an external connection part, which is used to connect the bracket 1 to an external object. In this way, through the provision of the external connection part, it is convenient to fix the bracket 1 on the external object to prevent the bracket 1 from tipping over.

[0060] Optionally, the external connection part is a bolt 9, and there are multiple bolts 9.

[0061] An optional implementation of this embodiment is as follows: it also includes a protective cover 10, which is arranged outside the bracket 1 and is detachably connected to the bracket 1. In this way, the possibility of components in the bracket 1 being damaged is reduced by the provision of the protective cover 10.

[0062] Optionally, the protective cover 10 is a structural member made of a transparent material. In this way, the protective cover 10 made of the transparent material makes it easier to observe the situation during the inspection of the electronic water pump.

[0063] Optionally, an emergency stop button is also included and installed on the bracket 1.
