Description
Technical field
The utility model relates to killer switch tooling, specially a kind of moulded case circuit breaker movable contact system half
Automatic assembling fixture.
Background technique
Moulded case circuit breaker is generally used as distribution, can also be used for protection motor, under normal circumstances, breaker
It can be used respectively as infrequently conversion and the infrequently starting of motor of route, moving contact part includes spring, pressing plate,
Spring is provided with an axis hole to install locating shaft on pressing plate, on pressing plate, is being assembled in bottom, moving contact setting
When, installation shaft operation is very troublesome, needs to overcome the lowermost spring, after being pressed onto designated position, put on by pressing plate
Shaft, this acting force of the spring is very big, and mode of operation general at present is by a kind of special fixture tool, and manpower goes to operate,
It is not only laborious, but also have higher requirements to the proficiency of operator, misoperation also has security risk, entire plastic shell
The installation effectiveness of formula breaker is by extreme influence.
Summary of the invention
The purpose of this utility model seeks to provide a kind of semi-automatic group of clamping of moulded case circuit breaker movable contact system
Tool is cooperated by cylinder, pressure head and fixing seat, and the assembly of movable contact system part is rapidly completed, and installation effectiveness is high and safe.
For achieving the above object, technical solution adopted in the utility model are as follows:
A kind of semi-automatic assembling fixture of moulded case circuit breaker movable contact system, it includes lower plate, upper plate, branch
Support column, lever arm, lever column, lever lower supporting rod, fine tuning strut, cylinder, pressure head, shaft positioning seat, lower plate, upper plate
Corner is connected and fixed by four support posts, and upper plate upper surface is fixedly connected under shaft positioning seat, fine tuning strut, lever
Column, cylinder lower end is hinged with lower plate, and cylinder is vertically arranged between lower plate, upper plate, and upper plate is provided with strip
Through hole, the piston rod of cylinder are threaded through hole, and top is hinged with distal end, and lever arm middle front part lower end is fixedly connected
There is lever column, lever column is vertical with lever arm, and lever column lower end and lever lower supporting rod upper end are hinged, and lever arm leading portion is solid
Surely it is connected with pressure head, cylinder piston rod movement drives lever arm swing, the pressure head upper and lower displacement of lever arm leading portion, and fine tuning strut is set
It sets immediately below lever arm front, the bottom offset amount of limit lever arm front, shaft positioning seat is arranged below pressure head, described
Shaft positioning seat is provided with positioning groove, to place moving contact shaft installation seat mechanism.
The device further includes cylinder control switch, controls the raising and lowering of cylinder piston rod.
The positioning groove shape of the shaft mounting base is consistent with the outer dimension of moving contact shaft mounting base, moving contact
After shaft mounting base is placed in positioning groove, will not all around it shake.
The working process of the utility model is as follows: the most intermediate phase shaft in moulded case circuit breaker moving contact position is installed
Seat is placed in positioning groove, and manipulation cylinder piston rod rises, then lever arm leading portion pressure head declines, by the pressure in shaft mounting base
Plate pushes, and the height by finely tuning strut goes to limit the amplitude of pressure head decline, avoids over-voltage, after pressing plate is pressed onto designated position,
The connection of shaft fixation clip Yu shaft mounting base is put on, which installs, and operation cylinder lifts lever arm pressure head, complete
At the assembly of other two-phase shaft mounting base.
The utility model has the following beneficial effects: comparing existing manual operation mounting means, simpler, time saving province is operated
Power, and safety, greatly improve the installation effectiveness of moulded case circuit breaker moving contact position shaft.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
