Circuit breaker contact system processing equipment

Abstract

The invention discloses circuit breaker contact system machining equipment. The circuit breaker contact system machining equipment comprises a welding device and a rotary disc; the edge of the welding device and the edge of the rotary disc are installed in a corresponding mode; at least one welding fixture is installed at the edge of the rotary disc; and the rotary disc can drive the welding fixtures to rotate to welding positions so that welding can be conducted. Each welding fixture comprises a front end fixture body for installing a busbar and a rear end fixture body for installing a moving contact set and a flexible connection set which are connected with each other, and one end of the flexible connection set can be installed in a busbar groove set correspondingly formed in the end of the busbar. The welding device comprises an electrode structure for welding, and the electrode structure and each front end fixture body are arranged in a corresponding mode so that each flexible connection set can be in welding connection with the busbar groove set formed in a corresponding mode. The circuit breaker contact system machining equipment provided by the invention is precise in welding machining and high in automation degree and product consistency.

Description

technical field [0001] The invention relates to the field of electric appliance assembly, in particular to processing equipment for a contact system of a circuit breaker. Background technique [0002] At present, the welding process of the circuit breaker contact system adopts manual welding after the busbar and the flexible connection group with multiple moving contacts are fixedly connected with a simple fixture. However, this welding method cannot make the position and size of the soft connection group and the end of the busbar seat consistent, and it is easy to cause different burning conditions between the contacts of the moving contact, resulting in unstable operation of the contact system and poor reliability. At the same time, the simple fixture cannot be compatible with contact systems of various specifications, resulting in low fixture use efficiency and affecting the welding processing efficiency of the contact system.

Problems solved by technology

However, this welding method cannot make the position and size of the soft connection group and the end of the busbar seat consistent, and it is easy to cause different burning conditions between the contacts of the moving contact, resulting in unstable operation of the contact system and poor reliability.

At the same time, the simple fixture cannot be compatible with contact systems of various specifications, resulting in low efficiency of fixture use and affecting the welding processing efficiency of the contact system

[0003] The existing circuit breaker contact system welding device uses the upper electrode and the lower electrode to be installed correspondingly and conducts electric heating and welding on the pressed busbar. The welding heat is lost along the busbar, which affects the quality of welding products and reduces the qualified rate of welding products

At the same time, since the end of the busbar has multiple busbar grooves, the existing welding electrodes need to undergo repeated welding to complete the welding process, but repeated welding will lead to inconsistent welding effects of each busbar groove, reducing the quality of the product. The pass rate, and the electrode material is repeatedly softened, and the electrode consumption is large, which may easily cause the electrode to fall off

[0004] The existing circuit breaker contact system processing equipment is mostly manual processing, which cannot realize the process of automatic loading, welding and unloading of busbars and soft connection groups, resulting in low processing and welding efficiency, and can not guarantee the quality of welding products. Consistency reduces product yield
