The invention discloses a potentiometer aging screening device table which comprises a frame, a shell, a stepper motor, a cam, a roller, a guide rail, a rack, a gear, a pressure plate assembly, a connector, a bearing seat and a gear shaft. The cam is arranged on an output shaft of the stepper motor; the roller is connected with one end of the guide rail and is matched with the cam; a quantity of the rack is two; the two racks are respectively arranged on two sides of the guide rail; the gear through the bearing seat and the gear shaft is installed on the frame; the gear is fixed on the gear shaft and is meshed with the rack; the stepper motor, the cam, the roller, the rack, the guide rail, and the gear form a positive and negative power transmission system; the bearing seat is arranged on the frame; one end of the gear shaft is connected with the bearing seat, and the other side of the gear shaft through the connector is connected with a to-be-tested potentiometer; the to-be-tested potentiometer is positioned on shell; and outside of the to-be-tested potentiometer is fixed by the pressure plate assembly. The potentiometer aging screening device table is simple in structure, reasonable in design, good in use effect, low in manufacturing cost, high in efficiency, and small in size.
Description
technical field [0001] The invention belongs to the technical field of potentiometers, and in particular relates to a potentiometer aging screening device platform. Background technique [0002] The aging test of the potentiometer is a necessary means to eliminate the early failure of the potentiometer and control the product quality. The reliability of the contact between the carbon brush and the resistor inside the potentiometer is an important technical indicator of the quality of the potentiometer, which directly affects whether the potentiometer can be used effectively. Because the carbon brush of the potentiometer is inside, it is invisible from the outside, and its service life is more than 10,000 times. Therefore, the reliability of judging the quality of the potentiometer by only one or several power-on and power-off is not ideal. The existing potentiometer aging screening device has the disadvantages of complex structure, large volume, high cost and low efficienc...
