Abstract

The invention relates to a welding tool of breaker spindle connecting levers. The welding tool comprises a support seat, wherein at least two connecting lever positioning pieces are arranged on the support seat and are used for being in location fit with a spindle and positioning corresponding connecting levers on the spindle; each of the connecting lever positioning pieces comprises an axial positioning part and an angle positioning part; the axial positioning part is used for being matched with the space between corresponding connecting levers on the spindle; and the angle positioning part is used for being in location fit with corresponding connecting levers to enable the connecting levers to keep relative angles. The at least two connecting lever positioning pieces used for positioningcorresponding connecting levers on the spindle are arranged on the support seat; and the axial positioning part used for being matched with the space between corresponding connecting levers on the spindle and the angle positioning part used for being in location fit with corresponding connecting levers to enable the connecting levers to keep relative angles are arranged on each of the connectinglever positioning pieces, so that the demanded position and angle requirements when the connecting levers are welded on the spindle are ensured and the welding error is reduced.

Description

technical field [0001] The invention relates to a welding tool 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 com...
