Bridge-shaped contact riveting clamp of frame circuit breaker and assembly operation method of bridge-shaped contact riveting clamp

Abstract

The invention relates to a riveting clamp, and in particular to an assembly operation method of a bridge-shaped contact riveting clamp of a frame circuit breaker. The riveting clamp comprises bridge-shaped contacts and a bottom plate; two clamping devices which are distributed at an interval are arranged on the bottom plate; the bridge-shaped contacts which are detachably fixed are respectively arranged in the clamping devices; a punch riveting device is arranged between the two clamping devices; and the punch riveting device synchronously controls the two clamping devices. The high riveting speed is fast, and efficiency is high.

Description

technical field [0001] The invention relates to a riveting fixture, in particular to an assembly operation method for a bridge-shaped contact riveting fixture of a frame circuit breaker. Background technique [0002] The main function of the bridge contact of the frame circuit breaker is to quickly connect or separate the circuit breaker body and the conductor of the drawer seat. It is suitable for quickly pulling out from the drawer seat when the body fails, and is convenient for maintenance. The commonly used bridge-shaped contact structure mainly includes: spacers, springs, small shafts, contacts, brackets, and pins. The two ends of the spring are respectively hooked on the small shafts in the semicircular arcs outside the contacts on both sides. There is a groove in the middle of the small shaft so that the hooks at both ends of the spring can be hooked. The bridge contact riveting method of the traditional frame circuit breaker is to use the conical surface to resist t...

Problems solved by technology

The bridge contact riveting method of the traditional frame circuit breaker is to use the conical surface to resist the end hole of the bridge contact pin, and manually hammer the pin to expand to achieve the purpose of riveting. This method is often difficult due to uneven artificial force. The contact of the bridge-shaped contact is riveted to the pin, so that the two cannot rotate flexibly, and the end of the pin is riveted, so that the workpiece is scrapped; on the other hand, manual riveting workers have high labor intensity and slow riveting speed, which often cannot meet the requirements.
