[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An automatic potentiometer testing fixture includes: a fixture base, a test cylinder support plate, and a test cylinder fixing plate. The test cylinder support plate is disposed on the fixture base, and the test cylinder fixing plate is disposed between the test cylinder support plates. A test cylinder is disposed on the test cylinder fixing plate. The test cylinder is connected to an upper mold fixing plate via a telescopic rod. A guide post is movably sleeved in the positioning hole of the upper mold fixing plate. The upper mold fixing plate is connected to an upper template via a support post. A carrier plate is disposed on the fixture base of the upper template, and a potentiometer fixing plate is disposed on the carrier plate.
[0007] The upper template is provided with a slide rail structure, which includes a micro servo motor, a slide rail, and a needle mold module. The micro servo motor drives the needle mold module through the slide rail.
[0008] The needle mold module includes a servo slide rail connecting block, a servo slide rail pad block, and a slide rail fixing block. The servo slide rail connecting block is connected to the slide rail fixing block through the servo slide rail pad block.
[0009] A brush slider fixing plate is connected to the slide rail fixing block via a brush mounting plate, and a needle mold is provided on the brush slider fixing plate.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] By testing the cylinder drive, the upper mold fixing plate moves the upper template up and down, and the micro servo motor drives the needle mold module to slide back and forth on the slide rail to test the potentiometer mounted on the potentiometer fixing plate of the carrier plate, thus improving the testing efficiency.
[0012] Furthermore, the machine has a simple structure and is easy to operate, which reduces the difficulty for staff to test potentiometers and improves efficiency. Attached Figure Description
