When the distance between the gear and the gear mounting surface is too long or too short, it will affect the transmission of the battery gear. In fact, when the distance between the gear and the gear mounting surface is too long, it will cause the gear to wobble or produce abnormal noise during rotation. Therefore, it is necessary to measure the distance between the gear and the gear mounting surface. Existing gear height detection fixtures are difficult to use to detect the gear mounting height of motors and gears of different sizes. Utility Model Content

[0032] The lower end of the tooling body 1 is provided with a clamping component 2, which is used to clamp the motor 3;

[0033] The motor 3 has a gear mounting surface 31 and a motor shaft 32 located on the gear mounting surface 31. A gear 4 is mounted on the end of the motor shaft 32 that is away from the motor 3.

[0036] The first distance sensor 51 is located on the inner top wall of the tooling body 1. The first distance sensor 51 is used to detect the distance between the first distance sensor 51 and the gear mounting surface 31, and to feed back the first distance detection signal to the controller 54.

[0037] The horizontal adjustment component 6 is mounted on the tooling body 1. The driving end of the horizontal adjustment component 6 is connected to the second distance sensor 52, enabling the second distance sensor 52 to move horizontally. The second distance sensor 52 is located on the inner top wall of the tooling body 1, inside the first distance sensor 51. The second distance sensor 52 is used to detect the distance between the second distance sensor 52 and the upper surface of the gear 4, and to feed back the second distance detection signal to the controller 54. Specifically, the horizontal adjustment component 6 moves along the length direction of the tooling body 1 (…). Figure 1 The distance sensors are configured in a left-right direction. The detection ends of both the first distance sensor 51 and the second distance sensor 52 are downwards and flush with each other. Both the first distance sensor 51 and the second distance sensor 52 are infrared ranging sensors, model GP2Y0A02YK0F. These infrared sensors utilize the principle of infrared reflection to detect distance and feed back the distance detection signal to the controller 54, exhibiting advantages such as high sensitivity and fast response.

[0038] The comparator module 53 is used to compare the detection result of the first distance sensor 51 and the detection result of the second distance sensor 52.

[0039] The controller 54 is used to control the opening and closing of the prompting module 55 according to the comparison result of the comparator module 53. In this embodiment, the controller 54 is a microcontroller, preferably an STM32H series high-performance microcontroller.

[0040] In this embodiment, the comparator module 53 and the controller 54 are both located on the top of the tooling body 1, and the prompting module 55 includes a green indicator light and a red indicator light, both of which are electrically connected to the controller 54.

[0041] It also includes a start button and a stop button, both of which are electrically connected to the controller 54.

Through the cooperation of the first locking block 21 and the second locking block 22, the bottom left end of the tooling body 1 can quickly abut against the motor 3, thereby achieving rapid positioning of the tooling body 1. In this embodiment, the first distance sensor 51 is located near the edge of the left end of the tooling body 1 and is located to the right of the second locking block 22, which facilitates the first distance sensor 51 to detect the distance between the first distance sensor 51 and the gear mounting surface 31.

[0044] The screw 23 is threaded onto the right side wall of the fixture body 1. One end of the screw 23 extends to the left through the right side wall of the fixture body 1 and is fixedly connected to the abutment block 24. The left side wall of the abutment block 24 can abut against the outer side wall of the motor 3. The other end of the screw 23 extends to the right through the right side wall of the fixture body 1 and is fixedly connected to the handle 25. After the left end of the fixture body 1 is positioned, rotating the handle 25 drives the screw 23 to rotate to the left, and drives the abutment block 24 to move to the left until the abutment block 24 abuts against the right side wall of the motor 3, thereby completing the clamping and limiting of the fixture body 1's clamping assembly 2 on the motor 3, facilitating subsequent testing.

[0045] As a preferred embodiment, rubber pads are provided on the inner sidewall of the first locking block 21, the lower sidewall of the second locking block 22, and the left sidewall of the abutment block 24. By providing fixedly connected rubber pads on the inner sidewall of the first locking block 21, the lower sidewall of the second locking block 22, and the left sidewall of the abutment block 24, the clamping and fixing of the motor 3 is more stable when the inner sidewall of the first locking block 21, the lower sidewall of the second locking block 22, and the left sidewall of the abutment block 24 abut against the motor 3.

[0046] As a preferred embodiment, the horizontal adjustment assembly 6 includes a through groove 61, a mounting groove 62, a lead screw 63, a slide rod 64, a lead screw nut 65, and an adjustment block 66;

[0047] The through groove 61 is located in the middle of the top wall of the tooling body 1. The opening of the through groove 61 is vertically oriented. The first distance sensor 51 is located on the left side of the through groove 61.

In this embodiment, the lead screw 63 is rotatably connected to the side wall between the through groove 61 and the mounting groove 62. The upper part of the lead screw nut 65 is threaded onto the lead screw 63, and the lower part of the lead screw nut 65 is slidably fitted onto the sliding rod 64. The bottom of the lead screw nut 65 is fixedly connected to the second distance sensor 52. Based on the position of gear 4 on motor 3, rotating adjustment block 66 drives lead screw 63 to rotate. With the cooperation of slide rod 64, lead screw nut 65 moves horizontally along slide rod 64 until lead screw nut 65 drives second distance sensor 52 to move above the upper surface of gear 4, so that second distance sensor 52 can detect the distance between second distance sensor 52 and the upper surface of gear 4.

Through the cooperation of the first locking block 21 and the second locking block 22, the bottom left end of the tooling body 1 can quickly abut against the motor 3, thereby achieving rapid positioning of the tooling body 1. After the left end of the tooling body 1 is positioned, the handle 25 is rotated to drive the screw 23 to rotate to the left, and drive the abutting block 24 to move to the left until the abutting block 24 abuts against the right side wall of the motor 3, thereby completing the tooling body positioning. The clamping assembly 2 of body 1 clamps and limits the motor 3, facilitating subsequent testing. Based on the position of gear 4 on motor 3, rotating the adjusting block 66 drives the lead screw 63 to rotate. With the cooperation of the slide rod 64, the lead screw nut 65 moves horizontally along the slide rod 64 until the lead screw nut 65 moves the second distance sensor 52 above the upper surface of gear 4. Pressing the start button activates the fixture. The controller 54 controls the first distance sensor 51 and the second distance sensor 52 to start and perform detection. The first distance sensor 51 detects… The first distance sensor 51 detects the distance between itself and the gear mounting surface 31, and sends a first distance detection signal to the controller 54. The second distance sensor 52 detects the distance between itself and the upper surface of the gear 4, and sends a second distance detection signal to the controller 54. The comparator module 53 compares the detection results of the first distance sensor 51 and the second distance sensor 52. The controller 54 controls the opening and closing of the prompt module 55 according to the comparison result of the comparator module 53. Specifically, when the difference between the detection results of the first distance sensor 51 and the second distance sensor 52 is within a preset distance, the controller 54 controls the green indicator light to turn on and illuminate, indicating that the detected distance between the upper surface of the gear 4 and the gear mounting surface 31 of the motor 3 is qualified. When the difference between the detection results of the first distance sensor 51 and the second distance sensor 52 is not within a preset distance, the controller 54 controls the red indicator light to turn on and illuminate, indicating that the detected distance between the upper surface of the gear 4 and the gear mounting surface 31 of the motor 3 is unqualified.
