Abstract

The utility model relates to a rivet shaft mold used for assembling a tripping device of a circuit breaker, which is characterized by comprising a square bottom plate, a left locating block and a right locating block, which are fixedly connected with the bottom plate, and a punch; a groove is arranged at the middle of the plane of the bottom plate which is provided with a through hole near the center of the bottom plate; the left locating block and the right locating block are fixedly connected with both sides of the central connecting line between the groove at the bottom plate and the hole;a groove is arranged at the right side face of the left locating block; the punch is a step-type cylinder which is provided with a chord section cylinder parallel to the axis of the punch at the headpart of the punch. As the left locating block and the right locating block are adopted to locate and place the tripping device to be assembled and the punch is adopted to punch and rivet the not-flattened end of a torsion spring shaft of the tripping device to be assembled, the mold can ensure that the riveting of the torsion spring shaft during the assembly of the tripping device of the circuit breaker is simple and convenient, thereby lowering labor intensity of operators and improving working efficiency. In addition, the mold can effectively control assembly quality, ensures the stability of the product performance and improves the reliability of products.

Description

The riveting shaft positioner for assembling release of circuit breaker

Technical field

The utility model belongs to a kind of circuit breaker assembling mold, particularly relates to a kind of riveting shaft positioner for assembling release of circuit breaker of 630,800 housings.

Background technology

Present known circuit breaker is not made up of support, snap close, tripping, extension spring, torsion spring, the flat youngster's of an end band axle, a part such as axle with the level with the release of strutting piece and support.Extension spring is fitted together tripping and groups of holders, and tripping can be moved along the reserved track of support both sides.Axle with the flat youngster of an end band is fixed on the rear portion of support with snap close then,, a torsion spring is worn in this centre, and an end of this torsion spring rides on the step axle on the support, and the other end rides on the snap close, but latches in the effect flat youngster's of strip winding the axle motion down of torsion spring this moment.For preventing the flat youngster's of an end band the axle support of under the effect of spring force, scurrying out, adopted in the past and manually this was passed the other end of support with manually carrying out bending.Flat youngster's axle is stressed following three kinds of situations can to occur when big owing to be with.First kind: when angle of bend was not enough, this axle support of scurrying out easily caused release to detain again; Second kind of situation: when angle of bend is excessive, can influence the hasp distance of snap close and tripping, therefore release also can occur or else go up the button problem; The third situation: manually axle is carried out bending owing to utilize, be difficult to guarantee to carry out bending, thereby cause the play up and down of axle easily, cause buckling surface inconsistent, thereby influence the stability of product performance from root.And for preventing its distortion often the external diameter with this design is bigger, this has just brought certain difficulty to workman's assembling.So utilize pure manual crooked method, not only working strength of workers is big, production efficiency is low but also operator's working ability can directly influence assembly quality, thereby influences the overall permanence of circuit breaker.

Summary of the invention

The utility model for solve the technical problem that exists in the known technology provide a kind of can be to the riveting shaft positioner for assembling release of the circuit breaker fixed simply, easily with flat youngster's axle in the assembling process of 630,800 serial all size circuit breaker tripping devices.

The utility model for the technical scheme that solves the technical problem that exists in the known technology and take is: it includes a square floor, be connected in to be used on the described base plate to lay and to give from both sides and be assembled the left and right locating piece that release positions and be used for towards riveting as the be crushed drift of the torsion axis other end of an end that is assembled release; Middle part on one side, plane has one can hold the groove that is assembled release extension tension spring shaft on described base plate, and has one can insert the through hole that is assembled the release snap close near the center of this base plate; Described left and right locating piece is fixed on the both sides of the line of centres in groove on the described base plate and hole; Have at the right side, the left surface of described left and right locating piece and can avoid being assembled the fixedly groove of the sidewall of tripping crossbeam of the outstanding support of release; Described drift is a step cylinder, and the cylinder of its head is the cylinder that the flat-sawn face of parallel its axis is arranged.

The utility model can also adopt following technical scheme:

Middle part on one side, plane has one can hold the groove that is assembled release extension tension spring shaft on the described base plate, also can be a through hole.

Advantage and the good effect that the utlity model has are: will be assembled the placement of release location owing to adopted by the left and right sides locating piece that is fixed on the base plate, and with drift will be assembled the other end that the release torsion axis is not crushed carry out on the plane on the right locating piece making towards the mold of riveting simple to the work of torsion axis riveting axle in the release assembling of carrying out circuit breaker, made things convenient for, reduce operator's labour intensity, improved operating efficiency.And can control assembly quality effectively, prevent the upper and lower play of torsion axis, even the phenomenon of the support of scurrying out takes place.Ensure the stability of properties of product, thereby improved reliability of products.

Embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

As shown in Figure 4, be assembled 11, one on the axle that tripping 10 is arranged on the circuit breaker tripping device 9, hang torsion spring the be crushed axle 12 of wearing torsion spring and torsion spring 13 etc.

As shown in Figure 1, the left and right locating

piece

4,2 that useful screw 3 is fixed on base plate 5.Place the centre that circuit breaker tripping device 9 both had been placed on left and right locating

piece

4,2 that is assembled of attitude as shown in Figure 4,12 had both just in time placed on the upper surface of left and right locating

piece

4,2 in the torsion spring.In addition, on right locating piece 2, also have one and become the cylindrical drift 1 of staged.

As shown in Figure 2, a groove 6 and a square through hole 7 are arranged on base plate 1.

As shown in Figure 3, following of drift 1 have cylindrical parallel its axis thus the flat-sawn face and above and form between its cylinder that joins dash platform 8.

Using method is: the snap close that will be assembled the release 9 of circuit breaker is inserted downwards in the hole 7 of base plate 5, the two side of release 9 supports both contacted and was fixed wherein with the right side of left and right locating

piece

4,2, left wall, and this moment, torsion axis 12 both placed on the upper surface of right locating piece 2.End with drift 1 band flat-sawn face goes punching press torsion axis 12 not have one of flattening again, thereby has finished the riveting axle work in the assembling of circuit breaker release.
