Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of brush holder positioning devices, specifically a positioning device for brush holder detection. Background Technology
[0002] The brush holder is a core component of the motor, mainly used to fix the carbon brushes and ensure stable contact between them and the rotating parts. During the manufacturing process of the brush holder, its quality and performance need to be ensured through testing. This is achieved by plugging the power connector into the brush holder interface and checking for short circuits or open circuits in the circuit. This ensures stable current transmission and reduces power loss caused by electrical problems. During the testing process, the position of the brush holder usually needs to be positioned to prevent it from shifting during testing and to ensure the accuracy of the brush holder testing.
[0003] Current positioning devices for brush holder inspection still have shortcomings in practical use. The most obvious one is that current brush holders usually use positioning recesses and protrusions for positioning. That is, the brush holder has positioning recesses, which cooperate with positioning protrusions on the bracket to limit the position of the brush holder. The fixed-size positioning protrusions can only fit the positioning recesses of brush holders of a specific size. When inspecting brush holders of different sizes, the protrusions cannot cooperate with the new-size recesses, which reduces the applicability of the positioning device. Therefore, we propose a positioning device for brush holder inspection. Utility Model Content
[0004] The purpose of this invention is to provide a positioning device for brush holder detection, so as to solve the problems mentioned in the background art.
[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

Elastic elements for applying pressure to the clamping plates are provided on the movable plate. A protective plate is fixedly connected to the lower end of the side wall of the clamping plate. A through groove is provided at the lower end of the side wall of the movable plate to facilitate the sliding of the protective plate. The protective plate is used in conjunction with the connecting groove.
[0008] As a preferred technical solution of this application, the calibration component includes a detection head, and a support frame is fixedly connected to both ends of the top of the operating table. A telescopic cylinder is fixedly connected to the top of the support frame, and the power output end of the telescopic cylinder passes through the top of the support frame and is fixedly connected to the detection head.

A rotating rod is fixedly connected to the bottom of the rotating plate. One end of the rotating rod is rotatably connected to the inner cavity of the support box. One set of gears is fixedly connected to the lower end of the side wall of the rotating rod, and the other set of gears is rotatably disposed at the bottom of the inner cavity of the support box. The two sets of gears mesh with each other. A motor for driving the gears to rotate is fixedly connected to the bottom of the support box.
[0010] As a preferred technical solution of this application, the elastic element includes a spring, which is fixedly connected between the movable plate and the clamping plate, and the spring is located on the outside of the slide rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] In the scheme of this application:
[0015] 1. By rotating a disc on a rotating plate, and creating a connecting groove on the disc to support a bidirectional screw, the bidirectional screw is threadedly connected to a movable plate. A sliding rod and a clamping plate are slidably mounted on the movable plate. By driving the bidirectional screw to rotate, the movable plates at both ends move relative to each other. The movable plates, through the sliding rod, move the clamping plate relative to each other, and the clamping plate, through an elastic element, clamps the brush holder. A protective plate protects the bidirectional screw within the connecting groove, thus enabling the positioning of brush holders of different sizes and expanding the application range of the positioning device.
[0016] 2. By setting a worm gear in the mounting slot, the worm gear drives the worm wheel to rotate, which in turn drives the support shaft and the rotating disk to rotate. The motor drives the gear to rotate, which in turn drives the rotating rod and the rotating plate to rotate. This enables the rotating disk to revolve and rotate on its own axis, making it easy to adjust the detection position of the brush holder and convenient to use. Attached Figure Description
