Contact assembling jig with rotatable connecting levers

Abstract

The invention discloses a contact assembling jig with rotatable connecting levers, which is used for assembling a contact and an insulation pedestal of a low-voltage circuit breaker. The contact assembling jig has the technical scheme that a pedestal locating block is fixed on a soleplate; two connecting lever locating parts are fixed at two sides of the upper side of the soleplate, two C-shaped or U-shaped connecting levers are arranged at two sides of the upper part of the soleplate, the rotatable lower ends of the connecting levers are arranged next to the locating parts of the connecting levers, the rotatable end of each connecting lever is provided with a connecting lever lug boss matched with the connecting lever locating parts, and a press mechanism is fixedly connected above the connecting levers; the press mechanism comprises a press block, a threaded rod and guide levers, the press block is connected at the lower end of the threaded rod by screw threads, the guide levers arearranged at both sides of the threaded rod, and the guide levers are freely sleeved on the press block. The invention has the advantages that the press mechanism is rotated to one side by the connecting levers, so the assembly space at the upper part of the pedestal is unoccupied, thereby facilitating the direct assembly of the pedestal, a spring and the contact from the top to the bottom; the pressing position of the press block is confirmed by the connecting lever locating parts, thereby ensuring the assembly position and the assembly precision between the contact and the pedestal; the contact assembling jig has light weight and convenient movement, thereby reducing the labor intensity.

Description

technical field [0001] The invention relates to the technical field of low-voltage electrical equipment processing, in particular to an assembly fixture for a contact and an insulating base of a low-voltage circuit breaker. Background technique [0002] At present, the main function of the assembly jig for the contact and the insulating base used in the low-voltage circuit breaker is to assemble the contact on the insulating base. Such as figure 1 As shown, put the spring 12 in the groove on the upper part of the base 11, and then place the contact 10 with the shaft 5 on the spring 12, and each contact 10 bears the pressure of two springs, which is about 100N. The contact 10 is pressed down to the required position by the clamp located above the contact 10, so that the shaft 5 in the middle of the contact 10 falls into the semicircular groove 13 on the base 11. The entire assembly process requires high positional accuracy. , the fixture is subject to a certain spring force...
