Embodiment 1
[0074] Taking the base of a 3P molded case circuit breaker equipped with parts as an example, the working process of the automatic screw locking device for the base of the molded case circuit breaker of the present invention will be described.
[0075] Such as Figure 26 As shown, the base 11 of the 3P molded case circuit breaker equipped with component products is arranged sequentially from top to bottom with a group of lower holes for incoming wire screws 11-1, a group of lower holes for static contact screws 11-2, and a group of lower holes for frame screws 11 -3. The lower hole group 11-4 of the conductive double gold screw and the lower hole group 11-5 of the outlet screw. The screw hole group 11-1 for the incoming line consists of 3 locking holes, the static contact screw hole group 11-2 consists of 6 locking holes, and the rack screw hole group 11-3 consists of 2 locking holes The lower hole group 11-4 of the conductive double gold screw is composed of 6 locking holes,...

The invention provides an automatic screw locking device for a plastic case circuit breaker base. The automatic screw locking device for the plastic case circuit breaker base comprises a base input wire, a base output wire, a first screw locking circulating wire and a second screw locking circulating wire; the starting end of the first screw locking circulating wire is in butt joint with the baseinput wire; the tail end of the first screw locking circulating wire is in butt joint with a base transferring mechanism and the starting end of the second screw locking circulating wire through a base transferring mechanism; the tail end of the second screw locking circulating wire is in butt joint with the base output wire; a plurality of first screw feeding mechanisms are arranged on one side of the first screw locking circulating wire, and a plurality of first automatic screw locking mechanisms are arranged on the other side of the first screw locking circulating wire; a plurality of second screw feeding mechanisms are arranged on one side of the second screw locking circulating wire, and a plurality of second automatic screw locking mechanisms are arranged on the other side of the second screw locking circulating wire. According to the automatic screw locking device for the plastic case circuit breaker base, combined screws, of machine tooth belt flat gaskets and spring gaskets, at different positions of the plastic case circuit breaker base can be automatically locked, automatic one-time locking is achieved, the locking success rate is 100%, the automation degree is high, toomuch manual participation is not needed in the whole process, and the production efficiency is greatly improved.
Description
technical field [0001] The invention belongs to the technical field of screw installation equipment for molded case circuit breakers, and in particular relates to an automatic screw locking device for a base of a molded case circuit breaker. Background technique [0002] The combined screw with flat washer and spring washer is the most important way to improve production efficiency, but considerable difficulties and problems have been encountered on the road to automation; at present, the conductive system of the incoming line end is assembled on the base of the molded case circuit breaker, The middle frame and the static contact system at the other end need to be locked and fixed by 6 rows of 60 machine teeth with flat washers and spring washers. When locking the screws, the worker not only needs to hold the electric screwdriver or air screwdriver, but also turns over the base, puts the screw into the screw hole, and then performs the locking operation. Obviously, such an ...
