A circuit breaker contact silver dot welding device
By designing a collar and telescopic spring to cooperate between the contact and silver point clamping block, the problem of easy displacement of the silver point during welding was solved, achieving stable clamping of the contact and silver point and improving the welding yield.

AI Technical Summary
In existing technologies, the volume and width of the silver point of the circuit breaker contact are smaller than the contact itself. The clamp can only hold the contact, and the silver point cannot be held, which makes it easy for the silver point to shift during machine operation, affecting the yield rate.
The device employs a clamping assembly design, including a contact clamping block and a silver point clamping block. Through the cooperation of a collar and a telescopic spring, the silver point clamping block drives the contact clamping block to move, thereby achieving lateral clamping and fixing of the contact and silver point to prevent displacement.
It effectively prevents the silver spot from changing position due to vibration during the welding process, thus improving the welding yield.
