Abstract
The invention relates to a device for assembling a tension spring in a moulded case circuit breaker (MCCB) mechanism. The device comprises a gear box, gears, a rack, a handle, a rear guide block, an upper guide block, a lower guide block and a septum board, wherein the gears, the rear guide block, the upper guide block and the lower guide block are fixed in the gear box; the gears are fixed between the upper guide block and the lower guide block; the rack is clamped between the rear guide block and the gears and can slide up and down; the internal surface of the rear guide block is a slant; a boss is arranged in the middle of the rear guide block and is contacted with the rack; the internal surfaces of the upper guide block and the lower guide block are also slants and the slant angles of the internal surfaces of the upper guide block and the lower guide block are the same as the slant angle of the internal surface of the rear guide block; one end of the handle is fixed on the gear shaft and the other end of the handle is exposed out of the gear box; the gear box can freely rotate around the gear shaft; and the septum board is fixed outside the lower part of the rack.
Description
Technical field
The present invention relates to the circuit breaker product in the low voltage equipment, particularly a kind of breaker of plastic casing mechanism extension spring assembling device.
Background technology
Breaker of plastic casing mechanism complexity in the low voltage equipment, installation accuracy is had relatively high expectations, and does not have very difficulty of the auxiliary assembling of frock.The particularly assembling of extension spring in the operating mechanism, general assembling mode be end hook ring set with extension spring on screwdriver, hook ring provoked puts into bracket holes.This method wastes time and energy, and extension spring slides easily, and screwdriver damages the person.
Summary of the invention
Technical problem to be solved by this invention is that a kind of breaker of plastic casing mechanism extension spring assembling device simple to operate, time saving and energy saving, safe and reliable, simple for structure, easy to assembly, with low cost is provided.
Solving the technical scheme that its technical problem adopts is: design a kind of breaker of plastic casing mechanism extension spring assembling device, can be easily again the extension spring with in the breaker of plastic casing mechanism of safety be assembled on mechanism's main shaft and the mechanism rack.
Breaker of plastic casing of the present invention mechanism extension spring assembling device by gear box, gear, tooth bar, handle, back guide pad, go up guide pad, down guide pad, collude plate and form, gear, back guide pad, last guide pad, following guide pad are fixed in the gear box, gear is fixed between guide pad and the following guide pad, tooth bar is installed between back guide pad and the gear, and tooth bar can slide up and down; Back guide pad inner surface is the inclined-plane, and the middle part has boss to contact with tooth bar, and last guide pad is similarly the inclined-plane with following guide pad inner surface, and gradient is identical with back guide pad inner surface; Handle one end is fixed on the gear shaft, and an end exposes outside gear box, and can rotate freely around gear shaft; Collude plate and be fixed in the outside, tooth bar bottom.
Course of action is as follows in use for breaker of plastic casing of the present invention mechanism extension spring assembling device:
At first breaker of plastic casing mechanism extension spring assembling device is placed on the breaker of plastic casing body, mechanism's extension spring lower end shackle cover is hung on mechanism's main shaft, the upper end shackle is hooked in and colludes on the plate, the rotary handle driven wheel rotates, the gear driven tooth bar upwards slides, tooth bar is simultaneously along last guide pad, following guide pad and back guide pad bevel direction run-off the straight, and guide pad middle part boss is a fulcrum generation rotary movement later on, collude and after plate is slided upset with tooth bar is upward mechanism's extension spring upper end shackle is pushed to mechanism rack installing hole top, this moment release handle, tooth bar is subjected to guide pad, following guide pad and the restriction of guide pad inclined-plane, back can not vertical drops, fall behind mechanism's extension spring upper end shackle along the inclined-plane down and just in time fall in the mechanism rack installing hole, finish fittage.
Breaker of plastic casing of the present invention mechanism extension spring assembling device is simple in structure, and handling safety, convenience, laborsaving have improved installation rate to a great extent, have increased coefficient of safety.

Embodiment
As shown in the figure, breaker of plastic casing of the present invention mechanism extension spring assembling device by gear box 12, gear 4, tooth bar 7, handle 5, back guide pad 1, go up guide pad 6, down guide pad 3, collude plate 2 and form, gear 4, back guide pad 1, last guide pad 6, following guide pad 3 are fixed in the gear box 12, gear 4 is fixed between guide pad 6 and the following guide pad 3, tooth bar 7 is installed between back guide pad 1 and the gear 4, and tooth bar 7 can slide up and down; Back guide pad 1 inner surface is the inclined-plane, and the middle part has boss to contact with tooth bar 7, and last guide pad 6 is similarly the inclined-plane with following guide pad 3 inner surfaces, and gradient is identical with back guide pad 1 inner surface; Handle 5 one ends are fixed on the axle of gear 4, and an end exposes outside gear box 12, and can rotate freely around gear shaft; Collude plate 2 and be fixed in the outside, tooth bar 7 bottoms.
Course of action is as follows in use for breaker of plastic casing of the present invention mechanism extension spring assembling device:
At first breaker of plastic casing mechanism extension spring assembling device is placed on the breaker of plastic casing body 8, mechanism's extension spring 11 lower end shackle covers are hung on mechanism's main shaft, the upper end shackle is hooked in and colludes on the plate 2, rotary handle 5 driven wheels 4 rotate, gear 4 drives tooth bar 7 and upwards slides, tooth bar 7 is simultaneously along last guide pad 6, following guide pad 3 and back guide pad 1 bevel direction run-off the straight, and guide pad 1 middle part boss is a fulcrum generation rotary movement later on, collude plate 2 and the upper end shackle of mechanism's extension spring 11 is pushed to the installing hole top of mechanism rack 10 after with the upward sliding upset of tooth bar 7, this moment release handle 5, tooth bar 7 is subjected to guide pad 6, the inclined-plane restriction of following guide pad 3 and back guide pad 1 can not vertical drop, fall behind mechanism's extension spring 11 upper end shackles down along the inclined-plane and just in time fall in the installing hole of mechanism rack 10, finish fittage.
