Description

Technical Field

[0001] This utility model relates to the technical field of testing equipment, and in particular to a brake motor testing device. Background Technology

[0002] A brake motor is a special type of motor that combines an electric motor with a mechanical braking system. Its main function is to control the motor's operating state through an electronic control system and to quickly stop the motor using an internal electromagnetic braking device. When the motor is running, the electromagnetic braking device is de-energized, allowing the motor to rotate freely; when it needs to be stopped, the electromagnetic braking device is activated, applying braking torque to quickly bring the motor to a stop.

[0003] Each batch of brake motors undergoes random sampling inspection before leaving the factory. Inspectors test the quality of the brake motors using various methods, one of which is to determine internal damage through sound. They listen for sharp electromagnetic noise, bearing noise, or friction sounds during motor operation; a normal sound should be a uniform "humming" sound. Abnormal sounds may indicate problems such as bearing wear, stator loosening, or mechanical impact.

[0004] The current method involves manual listening, which requires operators to carefully listen to the brake motor at regular intervals. This limits the number of motors that each inspector can be responsible for and is extremely time-consuming. As the number of motors to be inspected increases, the number of inspectors required also increases, raising the company's inspection costs. Furthermore, manual listening is prone to oversight and cannot quickly identify whether there is a problem with the brake motor. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a brake motor testing device, which can increase the number of brake motors that the testing personnel are responsible for testing, reduce testing costs and improve testing efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A brake motor testing device includes a device body, the device body including a workbench with a brake motor mounting hole, and a testing part including a decibel sensor and a buzzer.

[0033] Reference Figures 1-3 As shown, the present invention discloses a brake motor testing device, which includes a device body 1. The device body 1 includes a worktable 11 with a brake motor fixing hole.

[0034] The top of the worktable 11 is equipped with a support. The support includes two upright plates 3, both of which are mounted on the top of the worktable 11. Both upright plates 3 are slidably connected to the worktable 11. Two symmetrical sliding grooves are formed on the top of the worktable 11, and guide rods are fixedly installed in each of the two grooves. A sliding block is fixedly installed at the bottom of each upright plate 3, and the guide rod passes through the corresponding sliding block. The guide rod and the sliding block are connected by a damped sliding connection.

[0035] When installing and removing the brake motor, move the two upright plates 3 to facilitate quick installation and removal of the brake motor by the operator.

[0036] A first fixing plate 31 is provided between the two upright plates 3. The first fixing plate 31 is located in the upper half of the upright plate 3, and a circular plate 32 is rotatably mounted on the first fixing plate 31. The circular plate 32 and the first fixing plate 31 are connected by damped rotation.

[0037] A connecting plate 33 is mounted on the circular plate 32. A horizontal moving component 4 is mounted on both the circular plate 32 and the connecting plate 33.

[0038] The horizontal moving assembly 4 includes two square sliding rods 41. A first through hole 42 is provided on the top of the circular plate 32. The two square sliding rods 41 are horizontally fixed in the first through hole 42. The connecting plate 33 passes through the first through hole 42, and both square sliding rods 41 pass through the connecting plate 33. The square sliding rods 41 are slidably connected to the connecting plate 33.

[0039] A positioning component 5 is provided on the connecting plate 33. The positioning component 5 includes two first fixing blocks 51, both of which are hollow inside. Both first fixing blocks 51 are fixedly mounted on one side of the connecting plate 33, and a square sliding rod 41 passes through the corresponding first fixing block 51.

[0040] Each first fixing block 51 has a first screw 52 threaded through its top, and the first screw 52 is threadedly connected to the corresponding first fixing block 51. A pressure block 53 is slidably disposed inside each first fixing block 51, and the first screw 52 is rotatably connected to the corresponding first fixing block 51. The position and height of the corresponding pressure block 53 can be adjusted by rotating the first screw 52.

[0041] The bottom of the pressure block 53 is directly opposite the top plane of the corresponding square sliding rod 41. An anti-slip pad is also glued to the bottom of the pressure block 53.

[0042] A height adjustment assembly 6 is also provided on the connecting plate 33. The height adjustment assembly 6 includes a second screw 61, which passes through the connecting plate 33 and is rotatably connected to the connecting plate 33. During the rotation of the second screw 61, the relative position between the second screw 61 and the connecting plate 33 does not change.

[0043] A second through hole 62 is provided on the side of the connecting plate 33 near the brake motor. The second through hole 62 is located between the two square sliding rods 41, and the second through hole 62 does not contact the two square sliding rods 41. A screw block 63 is provided on the second screw 61. The screw block 63 partially passes through the second through hole 62. The screw block 63 is slidably connected to the second through hole 62, and the screw block 63 is threadedly connected to the second screw 61.

[0044] The device body 1 also includes a detection unit 2. The detection unit 2 includes a decibel sensor 21 and a buzzer 22. The decibel sensor 21 and the buzzer 22 are connected to an external power supply. The decibel sensor 21 and the buzzer 22 are electrically connected. A microcontroller is installed inside the decibel sensor 21.

[0045] The support unit positions the decibel sensor 21 near the brake motor. The buzzer 22 is fixedly mounted on one side of one of the upright plates 3. The decibel sensor 21 is fixed to the end of the screw block 63 located on the outside of the connecting plate 33.

[0046] When the external volume exceeds the threshold set on the microcontroller, the decibel sensor 21 sends an electrical signal to the buzzer 22, causing the buzzer 22 to sound. The decibel sensor 21 and the buzzer are existing technologies and will not be described in detail here.

[0047] The implementation principle of the above embodiments is as follows:

[0048] The operator first installs the brake motor in the preset hole on the worktable 11.

[0049] Next, the operator pushes the two upright plates 3 so that the brake motor is directly below the first fixed plate 31. During the movement of the two upright plates 3, the connecting plate 33 does not contact the brake motor.

[0050] Next, the operator began adjusting the position of the connecting plate 33.

[0051] The operator pushes the connecting plate 33 to move it to the appropriate position. Then, the operator simultaneously rotates the two first screws 52. The first screws 52 drive the corresponding pressure block 53 to move, so that the pressure block 53 is in close contact with the corresponding square sliding rod 41. This operation fixes the position of the connecting plate 33.

[0052] Next, the operator rotates the second screw 61, which causes the screw block 63 to move along the height of the connecting plate 33. The screw block 63 then moves the decibel sensor 21 to the appropriate position.

[0053] Finally, the operator turned on the brake motor and the decibel sensor 21.

[0054] When the decibel sensor 21 detects an increase in volume, it activates the buzzer 22, which then sounds, immediately alerting the testing personnel.

[0055] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
