Abstract
The invention relates to a riveting shaft clamping fixture for assembling a circuit breaker release and an application method thereof, which is characterized in that the riveting shaft clamping fixture for assembling a circuit breaker release comprises a square bottom plate, a left locating block and a right locating block fixedly connected on the bottom plate, and a punch pin; a groove is arranged in the middle of one side of an upper plane of the bottom plate and a through hole is arranged nearby the center of the bottom plate; the left locating block and the right locating block are fixedly connected to two sides of the line of centers of the groove and a hole on the bottom plate; a groove is positioned at the right side face of the left locating block; and the punch pin is a stepped cylinder, of which the top is provided with a chord-section cylinder parallel to the axial line of the punch pin. The invention adopts the left locating block and the right locating block for arranging the release to be assembled in a fixed position and uses the punch pin for punching and riveting the other end which is not squeezed of a torsional spring shaft of the release to be assembled so as to ensure simple and convenient shaft riverting operation of the torsional spring shaft in the assembly of the circuit breaker release, thus reducing the labor intensity of operators and improving working efficiency, furthermore, being capable of effectively controlling assembly quality, ensuring the stability of product performance and enhancing the reliability of products.
Description
Technical field
The invention belongs to a kind of circuit breaker assembling mold, particularly relate to a kind of riveting shaft positioner for assembling release and using method of circuit breaker of 630,800 serial 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, and 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 present invention 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 present invention for the technical scheme that solves the technical problem that exists in the known technology and take for the riveting shaft positioner for assembling release of circuit breaker 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 extension spring shaft support 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 present invention can also adopt following technical scheme:
Middle part on one side, plane has one can hold the groove that is assembled release extension extension spring shaft support on the described base plate, also can be a groove.
The technical scheme that the present invention takes for the using method of the riveting shaft positioner for assembling release of circuit breaker for the technical problem that exists in the solution known technology is: the snap close that will be assembled the release of circuit breaker is inserted downwards in the hole of base plate, the two side of release bracket both contacted and was fixed wherein with the right side of left and right locating piece, left wall, and this moment, torsion axis both placed on the upper surface of right locating piece; End with drift band flat-sawn face goes the punching press torsion axis not have one of flattening again, thereby has finished the riveting axle work in the assembling of circuit breaker release.
Advantage and good effect that the present invention 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.
