Abstract
Present invention is mainly applied to diesel engine part processing technique fields, in particular to a kind of crankshaft unilateral side fillet rolling auxiliary device, including connecting bracket and single-wheel milled head, connecting hole is arranged in connecting bracket one end, other end setting adjustment swivel nut, idler wheel is arranged in single-wheel milled head one end base angle position, and adjustment bolt is arranged in the corresponding adjustment swivel nut of the other end.The present apparatus can decompose rolling power, solve the problems, such as discontinuity.The use of the device can solve the problem of crankshaft two end unilateral side fillet can not roll, to more comprehensively complete the rolling of crankshaft each section fillet, improve crankshaft overall performance.It is simple and reasonable, it is easy to accomplish.
Description
Technical field
The present invention relates to a kind of crankshaft unilateral side fillet rolling auxiliary devices, are mainly used in diesel engine part processing technology neck
Domain.
Background technique
Relatively broad application has been obtained on crankshaft fillet finish rolling hardening technology crankshaft of diesel engine, especially automobile-used crankshaft,
Often increase rolling step to improve its performance and fatigue strength；Axle journal fillet between cranking arm for two, because cranking arm conduct
Support, stress are more uniform；Since design needs, crankshaft driving end, free end often encounter trunnion only unilateral side need to add
The case where the case where work fillet thus has side fillet rolling stress, and the other side can not support stress, this results in rolling
Discontinuity can not carry out the position fillet rolling.Currently, some Crankshaft Machining enterprises support crankshaft two using pressure head is lengthened
The design scheme of end flanges, but it is too long pressure head occur, clamping remove the problem of unloading difficult, crankshaft rolling deformation, mostly not to above-mentioned
Position carries out rolling and processing, influences the service performance of crankshaft.
Summary of the invention
The technical problem to be solved by the present invention is providing a kind of crankshaft unilateral side fillet rolling auxiliary device, song can solve
The problem of axis both ends unilateral side fillet can not roll improves crankshaft to more comprehensively complete the rolling of crankshaft each section fillet
Overall performance.
Crankshaft unilateral side fillet rolling auxiliary device of the present invention, including connecting bracket and single-wheel milled head, connection branch
Connecting hole, other end setting adjustment swivel nut is arranged in frame one end, and idler wheel is arranged in single-wheel milled head one end base angle position, and the other end is corresponding
It adjusts swivel nut and adjustment bolt is set.
The connecting hole is set as threaded hole, and externally threaded connector is provided in threaded hole.
The connecting bracket is set as U-shaped, and open end is arranged downwards, can avoid the dry of crankshaft end flange and bracket
It relates to, is convenient for clamping workpiece.
The single-wheel milled head includes rolling ontology, and idler wheel is arranged in the rolling ontology lower left corner, and right end holds out against pressing plate, pushes up
Press installed thrust bearing between plate and rolling ontology, holds out against the right side setting adjustment bolt of pressing plate.
The main device by designing a set of auxiliary jacking, the rolling pressure F that will should be evenly distributed on two idler wheels
It is decomposed, it is made to be respectively acting on idler wheel F1 and side plane F2；Crankshaft rotates needs when to meet work, and milled head exists
Thrust bearing is loaded on one side, fillet rolling idler wheel is loaded onto the corresponding other side；And it needs according to lathe and crankshaft knot
Structure carries out the holding device design, interferes to avoid with crankshaft and lathe.
The beneficial effects of the present invention are:
The present apparatus can decompose rolling power, solve the problems, such as discontinuity.The use of the device can solve crankshaft two
It is whole to improve crankshaft to more comprehensively complete the rolling of crankshaft each section fillet for the problem of holding unilateral fillet that can not roll
Performance.It is simple and reasonable, it is easy to accomplish.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
In figure: 1, tailstock tool；2, connecting bracket；3, connector；4, swivel nut is adjusted；5, crankshaft；6, adjustment bolt；7, it pushes up
Press plate；8, single-wheel milled head；9, idler wheel；10, unilateral fillet axle journal.
Specific embodiment
The present invention is described further with reference to the accompanying drawing:
As shown in Figure 1, crankshaft unilateral side fillet rolling auxiliary device of the present invention, including connecting bracket 2 and single-wheel rolling
Connecting hole, other end setting adjustment swivel nut 4, the setting of 8 one end base angle position of single-wheel milled head is arranged in pressure head 8,2 one end of connecting bracket
Adjustment bolt 6 is arranged in idler wheel 9, the corresponding adjustment swivel nut 4 of the other end.Connecting hole is set as threaded hole, is provided in threaded hole outer
The connector 3 of screw thread.Connecting bracket 2 is set as U-shaped, and open end is arranged downwards.Single-wheel milled head 8 includes rolling ontology, rolling
Press the ontology lower left corner that idler wheel 9 is set, right end holds out against pressing plate 7, holds out against installed thrust bearing between pressing plate 7 and rolling ontology, top
Press the right side setting adjustment bolt 6 of plate 7.
The device can be installed directly in equipment, mainly according to machine tool structure, in 1 suitable position auger shell of tailstock tool
The connector 3 of connecting bracket 2 or bolt are fastened to connecting bracket 2 on tailstock tool 1, assemble adjustment swivel nut by pit
4, connecting bracket 2 pays attention to reserving the installation space of crankshafts all types of enough when designing；
Crankshaft 5 is lifted, pays attention to avoiding 2 position of connecting bracket when lifting, avoids collision and interfere；It is used after 5 clamping of crankshaft
Single-wheel milled head 8 on knurling machine is clamped in unilateral 10 position of fillet axle journal for needing to roll, and adjustment bolt 6 is screwed in and is adjusted
Swivel nut 4, and adjust and hold out against position and pressure, it is bonded rolling roller 9 preferably, starts lathe, crawl observes idler wheel 9 and is bonded feelings
Condition and motion profile can carry out the rolling and processing of unilateral fillet after no problem.Rolling power F can be decomposed into rolling in this way
F1 and F2, thus the case where avoiding unbalance stress.
When replacing crankshaft 5, it is long that adjustment bolt 6 can be changed according to crankshaft structure and unilateral 10 length of fillet axle journal of rolling
Degree rolls needs to meet the unilateral of different model crankshaft.
