Abstract

The invention provides an automatic screw locking mechanism for a molded case circuit breaker base. The automatic screw locking mechanism comprises a first air cylinder, a second air cylinder, a locking and attaching mechanism, a screw clamping head and a supporting frame, wherein the supporting frame comprises a slide rod, an upper supporting plate and a lower supporting plate; an upper double-rolling-ball bearing, a lower double-rolling-ball bearing, an ejector plate and a transverse frame arranged on the slide rod; the first air cylinder is arranged on the ejector plate; the upper double-rolling-ball bearing is connected with the upper supporting plate; the piston rod of the first air cylinder is connected with the upper supporting plate; the second air cylinder is arranged on the transverse frame; the lower double-rolling-ball bearing is connected with the lower supporting plate; and the piston rod of the second air cylinder is connected with the lower supporting plate. The screw clamping head comprises a base body, a feeding body, a bolt feeding part and two bolt clamping parts; the bolt feeding part is composed of a first connecting head and a tube body; and each bolt clamping part consists of a second connecting head, a transition part and a clamping head. By adopting a transmission mechanism with two stages of universal joints and the screw clamping head capable of enabling bolts to automatically align, the purposes of enabling the bolts to automatically align to locking and attaching holes, automatically increasing stator rotation twisting force and automatically locking and attaching bolts are realized.

Description

technical field [0001] The invention belongs to the technical field of circuit breaker screw installation equipment, and in particular relates to an automatic locking screw mechanism and a locking method for the 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,...
