Abstract
The utility model discloses the adjusting device of snapping amount between a kind of circuit breaker semiaxis and closing magnet master part, inaccurate to solve during snapping amount between circuit breaker semiaxis and closing magnet master part regulates the adjustment existed, the problem of stop screw frangibility in being out of shape by force.It comprises breaker mechanism side plate, closing magnet master part, semiaxis, half-axile sleeve is located at breaker mechanism side plate upper end, the separating brake baffle plate that it also comprises little cam, leans on little cam, little cam is fixed by screws on breaker mechanism side plate, little cam is that axle rotates with screw, and closing magnet master part is set on pivot pin, the sheathed lower end being fixed on breaker mechanism side plate of bearing pin, separating brake baffle plate is fixed on semiaxis, semiaxis is arranged with the torsion spring that separating brake baffle plate is resetted.The utility model snapping amount is easy to control, simple to operate, easy to adjust, does not damage parts, and structure is simple and clear, amount of parts is few.
Description
Technical field
The utility model belongs to adjusting device, is specifically related to a kind of adjusting device limiting snapping amount between circuit breaker semiaxis and closing magnet master part.
background technology part
Circuit breaker is in separating brake process, tripping electromagnet needs the tripping force overcoming circuit breaker tripping to make breaker open operation, and the size of tripping force directly can affect the reliability of breaker open operation, circuit breaker can be caused not divide lock or extend opening time when tripping force is excessive, time serious, scaling loss tripping electromagnet makes circuit breaker there is potential safety hazard.The too small meeting of tripping force causes "on" position to keep incessantly improper separating brake, affects the use of circuit breaker.So the size by changing circuit breaker tripping force when separating brake to the adjustment of snapping amount size between circuit breaker semiaxis and closing magnet master part, and the length of breaker open operation time can be adjusted, make the performance of circuit breaker be in optimum state.
The design feature of current adjusting device is: between circuit breaker semiaxis and closing magnet master part, snapping amount size regulates the snapping amount between semiaxis and closing magnet master part by the bending stop screw be resisted against on semiaxis separating brake baffle plate by force, the shortcoming existed is that bad control is random large, regulate not accurate enough, stop screw is frangibility in being out of shape by force, and not easily changes after damage.
Utility model content
The purpose of this utility model is to provide the adjusting device of snapping amount between a kind of circuit breaker semiaxis and closing magnet master part, inaccurate to solve during snapping amount between circuit breaker semiaxis and closing magnet master part regulates the adjustment existed, the problem of stop screw frangibility in being out of shape by force.
For achieving the above object, the utility model patent is by the following technical solutions: the adjusting device of snapping amount between a kind of circuit breaker semiaxis and closing magnet master part, comprise breaker mechanism side plate, closing magnet master part, semiaxis, half-axile sleeve is located at breaker mechanism side plate upper end, it also comprises little cam, the separating brake baffle plate leaned on little cam, little cam is fixed by screws on breaker mechanism side plate, little cam is that axle rotates with screw, closing magnet master part is set on pivot pin, the sheathed lower end being fixed on breaker mechanism side plate of bearing pin, separating brake baffle plate is fixed on semiaxis, semiaxis is arranged with the torsion spring that separating brake baffle plate is resetted.
The utility model rotates by simple the angle that the little cam rested on separating brake baffle plate changes separating brake baffle plate, the change of separating brake baffle angle drives semiaxis to rotate, semiaxis upper groove angle changes, and recess edge and closing magnet master part amount of lap change, and reaches the object regulating snapping amount.The utility model snapping amount is easy to control, simple to operate, easy to adjust, does not damage parts, and structure is simple and clear, amount of parts is few.By this device, snapping amount is changed in the allowed band of 0.5mm-2.5mm, thus adapt to the change requirement of brake-separating and tripping force.
Accompanying drawing explanation
Fig. 1 is the structural representation of the adjusting device of snapping amount between a kind of circuit breaker semiaxis and closing magnet master part;
Fig. 2 is the schematic diagram that the utility model adjusting device is installed on breaker mechanism;
Schematic diagram when Fig. 3 is the utility model adjusting device operation adjustment before the change of snapping amount;

Reference numeral implication is as follows: little cam 1, screw 2, separating brake baffle plate 3, semiaxis 4, torsion spring 5, closing magnet master part 6, pivot pin 7, breaker mechanism side plate 8, groove (9), snapping amount A.
Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
The adjusting device of snapping amount between a kind of circuit breaker semiaxis and closing magnet master part, comprise breaker mechanism side plate 8, closing magnet master part 6, semiaxis 4, semiaxis 4 is set in breaker mechanism side plate 8 upper end, it also comprises little cam 1, the separating brake baffle plate 3 leaned on little cam 1, little cam 1 is fixed on breaker mechanism side plate 8 by screw 2, little cam 1 with screw 2 for axle rotate, closing magnet master part 6 is set on pivot pin 7, the sheathed lower end being fixed on breaker mechanism side plate 8 of bearing pin 7, separating brake baffle plate 3 is fixed on semiaxis 4, semiaxis 4 is arranged with the torsion spring 5 that separating brake baffle plate 3 is resetted.Be provided with groove 9 bottom semiaxis 4, the top of closing magnet master part 6 leans against the edge of semiaxis 4 upper groove 9.
The utility model specific works principle: as shown in Figure 3-4: when needs adjustment closing magnet master part 6 is with semiaxis 4 lap-joint snapping amount A, first screw 2 is loosened, sheathed little cam 1 on it is that is rotatable, it is Fig. 4 position that little cam 1 turns clockwise by Fig. 3 change in location, separating brake baffle plate 3 is promoted at the medium and small cam 1 of rotary course, separating brake baffle plate 3 turns to Fig. 4 position by Fig. 3 position, along with the change in location of separating brake baffle plate 3, go to Fig. 4 position by the dextrorotation of Fig. 3 position with its fixing semiaxis 4 simultaneously, now semiaxis 4 changes with the snapping amount of closing magnet master part 6 recess edge lap-joint, 0.5mm is faded to by 2.5mm.Now screw 2 is screwed and little cam 1 position can be fixed, thus complete the adjustment of snapping amount size, and according to breaker open operation characteristic requirements, snapping amount can be selected arbitrarily between 2.5mm-0.5mm.Schematic diagram when Fig. 3 is the utility model adjusting device operation adjustment before the change of snapping amount, schematic diagram when Fig. 4 is the utility model adjusting device operation adjustment after the change of snapping amount, in Fig. 3, snapping amount is that in 2.5mm, Fig. 4, snapping amount is 0.5mm.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
