Automatic assembling and locking system for miniature circuit breaker

Abstract

The invention discloses an automatic assembling and locking system for a miniature circuit breaker. The automatic assembling and locking system is characterized in that a turntable assembly is arranged in the middle of a table top of a rack, sixteen base stations and eight upper cover stations are uniformly distributed on the turntable assembly in an indexing manner, each of the sixteen base stations is provided with a base jig for conveying bases; each of the eight upper cover stations is provided with an upper cover jig; a base conveying mechanism, an adjusting nut conveying mechanism, a nutinput part, a nut detection unit, an arc extinguishing cover conveying mechanism, an arc extinguishing cover detection assembly, an arc guide plate and contact supporting plate press-fitting conveying mechanism, a secondary press-fitting assembly, a screw locking mechanism, an upper cover feeding mechanism and a finished product discharging mechanism are arranged close to related stations; the turntable assembly comprises an output shaft, a turntable is fixed at the upper end of the output shaft; and three supporting frames are arranged below the turntable, and all the supporting frames jointly support the turntable to rotate upwards through balls in all ball supports. The automatic assembling and locking system for the miniature circuit breaker is novel in structure, stable in finished product quality and high in automation degree.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment and relates to an automatic assembly and locking system for a miniature circuit breaker. Background technique [0002] Micro Circuit Breaker is suitable for overload and short circuit protection of AC 50 / 60Hz rated voltage 230 / 400V, rated current up to 63A, and can also be used for infrequent operation of the line under normal conditions. It is mainly used in various places such as industry, commerce, high-rise buildings and residential buildings. The product should meet the standards of GB10963.1 and IEC60898. But currently in actual assembly, for example Figure 11 Among them, the package of the base and the upper cover is usually assembled by hand and riveted by hand. This method is relatively easy to close the moving contact and the fixed contact by using mechanical movement, but it is relatively easy to use a mechanical method to close the small circuit breaker. The moving conta...

Problems solved by technology

[0004] The purpose of the present invention is to provide an automatic assembly and locking system for miniature circuit breakers, which solves the problem of low assembly efficiency caused by manual assembly in the prior art, missing installation and detection, insufficient locking and assembly, and the base and upper cover can be separated. It is convenient to open and inspect, replace the static contact and the moving contact, and eliminate the problem of burning the plastic case caused by loose assembly
