Automatic assembly station and assembly method of moving contact bridge with installation track

Abstract

The invention discloses an automatic assembly station with an installation path for a movable contact bridge. A movable contact bridge feeding mechanism comprises a feeding mechanism bracket and a movable contact bridge assembly slide block, wherein the movable contact bridge slide block is arranged on the feeding mechanism bracket; a cam groove I for being horizontally pushed is formed in one side of a horizontal wall of the feeding mechanism; a cam groove II for being pushed by angle control is formed in the other side of the horizontal wall; the movable contact bridge assembly slide block comprises an assembly air cylinder, a drive arm, a movable contact bridge clamping device, a cam I and a cam II; a piston rod of the assembly air cylinder is connected with a rotating shaft of the cam I; the cam I and the cam II are fixed at one end of the drive arm; the cam I is correspondingly arranged in the cam groove I; the cam II is correspondingly arranged in the cam groove II; and the movable contact bridge clamping device is fixed at the other end of the drive arm. The movable contact bridge can be arranged on a breaker bracket by the station along the path of each cam groove, so that the problem of a position obstacle between the movable contact bridge and the breaker bracket caused by the shape of the movable contact bridge in the automatic installation process is solved.

Description

technical field [0001] The invention relates to the field of automatic assembly equipment, in particular to a moving contact bridge assembly station of the circuit breaker automatic assembly equipment. Background technique [0002] GV2 series motor circuit breakers cover the protection range of 0.1-32A, which have the functions of isolation, short-circuit protection, overload protection, phase loss protection and direct control; the breaking capacity is as high as 10-100kA, and the electric life is as high as 100,000 times, which is the life span of ordinary circuit breakers. 5 to 10 times of that; with -20 ~ +60 ℃ ambient temperature compensation function; with undervoltage tripping, shunt tripping, fault display, testing and other auxiliary functions. [0003] Such as figure 1 and figure 2 The structure of the GV2 series motor circuit breaker shown includes a circuit breaker bracket (3), a moving contact bridge (1), a push rod (2) and a moving contact bridge spring (4)....

AI Technical Summary

Problems solved by technology

Therefore, when using automatic assembly of GV2 series motor circuit breakers, if the dynamic contact bridge is installed horizontally, the dynamic contact bridge will be hindered by the breaker bracket due to the horizontal downward tilt of the contact section, making it impossible to install. Therefore, the industry is installing the dynamic contact bridge At the same time, the method of manual assembly is basically adopted, which has poor assembly accuracy and low efficiency.
