Welding device of breaker spindle connecting levers

Abstract

The invention relates to a welding device of breaker spindle connecting levers. The welding device comprises a support seat and a support stand column perpendicularly mounted on the support seat, wherein a spindle support face is arranged on the support seat and is matched with the end face at one end of a spindle in a sliding support manner; at least two connecting lever positioning pieces used for being in location fit with the spindle and positioning corresponding connecting levers on the spindle are rotatably assembled on the support stand column; and each of the connecting lever positioning pieces comprises an angle positioning part used for being in location fit with corresponding connecting levers to enable the connecting levers to keep relative angles. The support stand column perpendicular to the support seat is mounted on the support seat; and the connecting lever positioning pieces are rotatably assembled on the support stand column, so that the angle positioning parts on the connecting lever positioning pieces carry out angle positioning on all connecting levers, the situation during welding, the spindle and the connecting levers are rotated to enable a worker not to move to and fro and to weld the circumferential contact surface of the spindle and the connecting levers, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a welding device for a main shaft crank arm of a circuit breaker. Background technique [0002] In the prior art, vacuum circuit breakers are widely used because the arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are both high vacuum. advantage. [0003] The mechanical characteristics of the vacuum circuit breaker make it an important factor for its normal operation, and the mechanical characteristics are determined by the operating mechanism of the circuit breaker. Among them, the main shaft of the vacuum circuit breaker plays an important role in transmission during the operation of the operating mechanism. ,Such as figure 1 As shown, the main shaft 10 is provided with three pairs of the first crank arm 11, the second crank arm 12 and the third crank arm 13, wherein the first crank arm 11 and the third crank arm 13 are composed of two crank arm pieces, and the crank arm 13 is c...
