Description
Technical field
Tooling device is the utility model is related to, the processing auxiliary mould of the decentraction sink hole on shell part,
More particularly to a kind of shell part sink hole correction processing unit (plant).
Background technology
Shell part is one of mechanical component such as speed changer, engine fundamental parts, and it not only needs to keep each axle, tooth
Correct mutual alignment between the parts such as wheel, fork, bearing, it is also necessary to keep correctly being connected installation, ability with interfacing part
Ensure drive connection passing power in phase.Shell part is a closed polyhedron, the uneven cavity of inwall, chi
Very little precision and the accuracy of form and position are all higher, and cast structure is complicated, yielding, the complicated part of processing technology.As engine connects
Speed changer mouth face connecting hole is caused often to occur with the situation that engine can not be connected if face casts problem or processing problems.Clutch
In order to which structure design is compact on device housing engine joint face, alignment pin is designed as hollow locating ring structure, and design is heavy on housing
Platform hole, but in casting or process, bolt through-hole bias can cause main engine plants not install normally.This problem of generation
Shi Changyong settling mode has two kinds, first, disassembling transmission assembly, changes housing, and upper assembly line assembling, this to do over again again
The consumable accessorys such as bearing, oil sealing, snap ring, bolt need to be changed；The another kind mode of reprocessing is to use special positioning fixture, is done over again with lathe
Housing sink hole.This special positioning fixture manufacture difficulty is big, the cycle is long, difficult carrying, and the wind of gearbox of doing over again that collides be present
Danger.Therefore both modes of doing over again all are present time-consuming, and it is very high to reprocess cost, easily influences product and delivers, triggers customer to embrace
The problem of resentment.
Utility model content
The purpose of this utility model is to provide a kind of quick shell part sink hole device of doing over again, and changes existing change
The mode of doing over again of fast tank shell sink hole, realize and quickly correct shell part sink hole eccentricity issues of doing over again.
The utility model realizes above-mentioned purpose using following technical scheme.Shell part sink hole corrects processing unit (plant),
Including bushing plate, positioning core axle and drill bushing, the bushing plate is provided with stepped hole, and stepped hole is fixedly mounted by screw in bushing
Interior, bushing plate is connected by bolt with housing；The bushing periphery is provided with step, the stepped hole of the step and bushing plate
Match, step-like positioning hole is provided with the bushing；The periphery of the positioning core axle is provided with step, the periphery of the drill bushing
Step also is provided with, and positioning hole of the step of the step of positioning core axle and drill bushing with bushing matches.
The utility model has the advantage of bushing plate can realize that fast free positions with the positioning hole on housing, effect of doing over again
Rate is high.Housing part is not damaged in rework process, is safeguarded without changing consumable accessory or returning factory, it is steady quality of doing over again, reliable.Can be with
Applied to doing over again for shell part sink hole decentraction problem, use range is extensive.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model positioning states；
Fig. 2 is the structural representation of the utility model bore state；
In figure：1- positioning core axles, 2- bushings, 3- bolts, 4- bushing plates, 5- nuts, 6- drill bushings, 7- screws, 8- shells
Body.
Embodiment
In conjunction with accompanying drawing, the utility model is described in further detail.Referring to Fig. 1, shell part sink hole correction processing dress
Put, including bushing plate 4, positioning core axle 1 and drill bushing 6, bushing plate 4 are provided with stepped hole, platform is fixedly mounted by screw 7 in bushing 2
In rank hole, bushing plate 4 is connected by bolt 3 with housing 8；The periphery of bushing 2 is provided with step, the step and bushing plate 4
Stepped hole matches, and step-like positioning hole is provided with bushing 2；The periphery of positioning core axle 1 is provided with step, the periphery of drill bushing 6
Provided with step, and positioning hole of the step of the step of positioning core axle 1 and drill bushing 6 with bushing 2 matches.
Procedure of processing：Housing 8 is first set into position, bushing 2 is fixed on bushing plate 4 with screw 7；Bushing plate 4 is filled
Enter on housing 8, and insert positioning core axle 1 and positioned；Bushing plate 4 is fixed on housing 8 with bolt 3, nut 5；Then take out
Positioning core axle 1 is removed, then drill bushing 6 is loaded in the stepped hole of bushing plate 4；The sink hole of the decentraction of housing 8 is finally processed with electric drill.
When in use, its positioning core axle 1 determines the hole of bushing plate 4 and the dowel hole on housing class workpiece 8 to the utility model
Position；Bushing plate 4 is fixed on shell part by bolt 3, nut 5, fixes bushing 2 with screw 7, prevents bushing 2 from sliding, lining
Set 2 can reduce part and play guiding, correction effect to mill, the effect of protection hole, drill bushing 6.Then positioning core axle 1 is inserted into drill jig
In the dowel hole of the hole of plate 4 and housing class workpiece 8, then with bolt 3 housing class workpiece 8 and bushing plate 4 are fastened together,
Realize in rework process and rectify a deviation in place.The hole of bushing plate 4 positions with housing dowel hole fast free, efficiency high of doing over again.It can answer
For doing over again for the various sink hole decentraction problems of housing class workpiece 8, use range is extensive.Rework process does not damage housing zero
Part, safeguarded without changing consumable accessory or returning factory, it is steady quality of doing over again, reliable.
