Power frequency withstand voltage retest tool for mutual inductor

Abstract

The invention discloses a mutual inductor power frequency withstand voltage retest tool which comprises a first conveying belt, a second conveying belt and a test board, a bent arm is installed on the side wall of the test board through a driving mechanism, two sliding grooves are symmetrically formed in the side, facing the test board, of the bent arm, and inclined plates are rotationally arranged in the two sliding grooves. And a fixing block is jointly and rotationally supported at the ends, away from the bent arm, of the two inclined plates, an electric telescopic rod is installed on the fixing block, the output end of the electric telescopic rod is fixedly connected with a hollow push rod, and a second electromagnet is installed in the hollow push rod. The angle change between the two inclined plates can change the distance between the electric telescopic rod and the positioning table, the maximum displacement distance of the hollow push rod is relatively increased, on one hand, the extension length of the output end of the electric telescopic rod can be shortened, the axial pressure of the electric telescopic rod can be reduced, and on the other hand, the space occupied by the electric telescopic rod and the hollow push rod is reduced. And the structure of the device is more compact.

Description

technical field [0001] The invention relates to the technical field of transformer production, in particular to a transformer power frequency withstand voltage retest tooling. Background technique [0002] After the transformer is assembled, its performance needs to be tested in batches. The routinely used transformer power frequency withstand voltage retest tooling needs to be fixed one by one by the staff. The efficiency and accuracy of manual operation depend on the working status of the staff. Therefore, in the traditional detection process, the problem of missing unqualified transformers is prone to occur. A patent document with the application number CN201811478279.9 proposes a A transformer detection and calibration equipment, which completes the detection of the transformer through the mutual cooperation of a rotary detection table, a transformer installation station, a defective product rejection station, a qualified product identification station, a finished produc...
