Description
Technical field
The utility model relates to Automatic manual transmission press-loading apparatus, is specially a kind of gear bushing press-mounting fixture.
Background technology
When gear lining press-fits, gear hub has an inclined oil hole of air, jacket wall also has an oilhole, need to realize after lining press-in bore, the inclined oil hole of air of gear will align coincidence with the oilhole of lining.
Adopt traditional frock, need first lining and gear all to be loaded in the endoporus in frock, what recycling frock inner hole wall inwardly stretched out can the alignment pin of resilience insert in the oilhole of two parts respectively, because these two can the alignment pin of resilience be in the same plane crossing frock axis, just can ensure that the correct position of two oilholes, so after putting pressure head press-in lining, realize oilhole and align coincidence; But its shortcoming of the structures shape of this frock, the wheel hub cylindrical being exactly lining and gear all will load in frock endoporus, and the endoporus of these two different sizes need have suitable fit clearance with lining and gear hub cylindrical, should load and unload easily, again can not gap too large, otherwise affect two oilholes and align.
In practical operation, the outer fenestra of lining and gear hub has and manufactures and heat treatment variation tolerance, and time has and feeds back bad handling, and non-cutting time is long, or have individual product two oilhole to stagger 1/3, and and the key component of former frock---can the locating pin structure design of resilience not easily process.
Summary of the invention
The utility model, in order to solve the existence operation when assembling and pressing of existing lining and gear and waste time and energy and the poor problem of precision, provides a kind of gear bushing press-mounting fixture.
The utility model adopts following technical scheme to realize: gear bushing press-mounting fixture, comprise base, base center is fixed with axle, base upper end is fixed with gear alignment pin, be installed with pass between axle and base to sell through joint efforts, mandrel sidewall is installed with and is horizontally disposed with and endoporus front-end surface is the spring housing of the conical surface, the top of spring housing is provided with the locking jackscrew being positioned at axle, the front end of spring housing is provided with the steel ball being stuck in its port, steel ball rear portion is provided with goring push spring, goring push spring rear end is provided with spring jackscrew, spring housing rear end is provided with the adjustment jackscrew be screwed in axle, axle top cover has pressure head.
During operation, first by gear paperback on base, the alignment pin on base also will insert in the aperture of gear face, gear lower surface is contacted completely with base, realizes the location of gear; Again lining is inserted in axle, the steel ball that axle is protruded blocks the hole in jacket wall, realizes lining location; During because manufacturing, the gear alignment pin on the steel ball that axle is protruded and base is sold through joint efforts by pass and associated, gear and lining is so just made to be provided with mutually correct position relationship, finally load onto pressure head press-in lining, overcome the existence when assembling and pressing of existing lining and gear and operate and waste time and energy and the poor problem of precision.
The utility model reasonable in design is reliable, cargo handling process is convenient and swift, improve operating efficiency, and be convenient to visual examination oilhole and whether align, the assembly qualified rate of product brings up to 100%, simplifies the complexity of mandrel structure simultaneously, also just reduces the difficulty of processing of axle, improve lining positioning precision, there is simple, the easy to process and advantage that cost is low of structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-base, 2-axle, 3-gear alignment pin, 4-closes and sells through joint efforts, and 5-spring housing, 6-locks jackscrew, 7-steel ball, 8-goring push spring, 9-spring jackscrew, and 10-regulates jackscrew, 11-pressure head, and 12-carries groove.
Detailed description of the invention
Gear bushing press-mounting fixture, comprise base 1, base 1 center is fixed with axle 2, base 1 upper end is fixed with gear alignment pin 3, be installed with pass between axle 2 and base 1 and sell through joint efforts 4, axle 2 sidewall is installed with and is horizontally disposed with and endoporus front-end surface is the spring housing 5 of the conical surface, the top of spring housing 5 is provided with the locking jackscrew 6 being positioned at axle 2, the front end of spring housing 5 is provided with the steel ball 7 being stuck in its port, steel ball 7 rear portion is provided with goring push spring 8, goring push spring 8 rear end is provided with spring jackscrew 9, spring housing 5 rear end is provided with the adjustment jackscrew 10 be screwed in axle 2, axle 2 top cover has pressure head 11.
In specific implementation process, base 1 has a pair with the gear loading hatch of its axle center symmetry, and base 1 bottom has a pair and the carrying groove 12 of its axle center symmetry, gear loading hatch is convenient to workpiece loading and unloading, carrying groove is convenient to carrying tooling, convenient to operation, stop the generation of worker injuries's phenomenon in operating process.
During operation, by regulating jackscrew 10 regulating spring pipe 5 position in hole, make the steel ball position suitable that axle is protruded, use locking jackscrew 6 holddown spring pipe 5 above again, not only realize the location of lining, also will when lining press down, steel ball recoil position is desirable, does not scratch lining or block lining to move down.
