Abstract
The invention discloses a small-end journal round corner rolling device for a crankshaft. The invention has the technical scheme that the small-end journal round corner rolling device for the crankshaft comprises a rolling body and a support roller sleeved on the small-end journal of the crankshaft; a mandrel is arranged on the rolling body; a guide roller is arranged on the mandrel through a needle roller bearing; the rolling body is provided with a roller retaining seat; a large roller and a small roller are arranged between the guide roller and the roller retaining seat; the lower end of the large roller corresponds to the position of a round corner to be rolled; a balancing sleeve is sleeved on the small-end journal of the crankshaft; the lower end of the small roller presses against the support roller and the balancing sleeve; and the small roller, the support roller and the balancing roller radially and axially limit the small-end journal of the crankshaft. The invention has the beneficial effects that the small-end journal round corner rolling device has simple structure and rational design; the problem of difficulty in the round corner rolling of the small-end journal of the crankshaft can be effectively solved; and with the adoption of the technical scheme, the rolled crankshaft is slightly deformed, the rolling effect is good, and the machining quality of the product and labor productivity are improved.
Description
Technical field
The present invention is a kind of bent axle microcephaly axle journal fillet rolling device.
Background technology
Bent axle is one of strength member in the engine, and its mechanical performance directly determines the life-span of engine.The form that bent axle lost efficacy generally has two kinds of journal wear and fatigue fractures.For fatigue fracture, generally adopt the mode of axle journal fillet rolling to improve its fatigue strength.Being applied to the milled head of round corner rolling process, generally is two pair of rollers bilateral fillet roll extrusion simultaneously that size is identical, and its axial force is cancelled out each other.But need the bent axle of roll extrusion for microcephaly's axle journal fillet, owing to have only a fillet, roll extrusion can't realize balance; Because general bent axle microcephaly length is obviously greater than all the other axle journals, as adopting the terminal method that increases auxiliary fillet of microcephaly, then milled head weight obviously increases; The distortion in rolling amount is very big; Defective such as often cause that bent axle is scrapped, therefore, bent axle microcephaly axle journal fillet rolling implements the comparison difficulty.
Summary of the invention
The present invention is directed to the deficiency of prior art, provide a kind of simple in structure, reasonable in design; Can effectively solve the problem of bent axle microcephaly axle journal roll extrusion fillet difficulty, adopt the present technique scheme, little through the crankshaft deformation of roll extrusion; Roll extrusion is effective, has improved product processing quality and labor productivity.
The present invention realizes through following technical measures: a kind of bent axle microcephaly axle journal fillet rolling device; Comprise the roll extrusion body, be sleeved on the supporting roller on the bent axle microcephaly axle journal, on the roll extrusion body axle is installed, through needle bearing guide wheel is installed on the axle; Said roll extrusion body has roller and keeps seat; Said guide wheel and roller keep seat big roller and trundle to be installed between going up, said big roller lower end with treat that roll extrusion fillet position is corresponding, be set with balance set on the said bent axle microcephaly axle journal; The trundle lower end is against support ball peace weighing apparatus and puts, and said trundle, supporting roller and balance set are radial and axial spacing to bent axle microcephaly axle journal.
Concrete characteristics of the present invention also have, and said balance set outboard end is provided with the top locating hole of lathe.
Beneficial effect of the present invention is: adopt the processing of balance set and big or small roller type milled head; Solved the shortcoming that the milled head volume is big, weight is big, distortion in rolling is big in the past effectively; Product processing quality and labor productivity have been improved; Adopt this mode roll extrusion, can confirm the width of milled head, the diameter of roller flexibly, make it reach optimised process property.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention.
Fig. 2 is the right view of Fig. 1.
Among the figure, 1, bent axle, 2, roller keeps seat, 3, guide wheel, 4, the roll extrusion body, 5, axle, 6, needle bearing, 7, trundle, 8, balance set, 9, lathe is top, 10, supporting roller, 11, big roller, 12, roller location shoulder, 13, positioning ring groove.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, through a specific embodiment, this programme is set forth below.
Shown in accompanying drawing; A kind of bent axle microcephaly axle journal fillet rolling device; Comprise roll extrusion body 4, be sleeved on the supporting roller 10 on the bent axle microcephaly axle journal, axle 5 is installed on the roll extrusion body 4, through needle bearing 6 guide wheel 3 is installed on the axle 5; Said roll extrusion body 4 has roller and keeps seat 2; Said guide wheel and roller keep seat big roller 11 and trundle 7 to be installed between going up, said big roller 11 lower ends with treat that roll extrusion fillet position is corresponding, trundle 7 and 10 couples of bent axle microcephalies of supporting roller axle journal are radial and axial spacing.
Wherein, Guide wheel 3 middle parts are provided with roller location shoulder 12; The diameter of shoulder 12 inboards, roller location of said guide wheel 3 is less than the diameter in the outside; The inboard and the roller of said roller location shoulder 12 keeps between the seat 2, the outside and the roller of roller location shoulder 12 keep being separately installed with big roller 11 and trundle 7 between the seat 2, the balance set 8 that has internal diameter and bent axle microcephaly axle journal external diameter to equate or adapt, and the medial extremity of said balance set 8 is provided with positioning ring groove 13; The lower end of said trundle 7 is positioned at positioning ring groove 13, and said bent axle microcephaly axle journal is through supporting roller 10, trundle 7, balance set 8 axial and radial locations.Balance set 8 outboard end are provided with the top locating hole of lathe.The diameter at above-mentioned guide wheel 3 two ends differs, and concrete numerical value is confirmed by the linear velocity of large and small roller.
During installation; The left side flange end of bent axle 1 links to each other with the headstock of knurling machine; Clamp with chuck (or other clamping mode), bent axle microcephaly axle journal end puts balance set 8, the locating hole that holds out against on the balance set with lathe top 9 again; With trundle 7 and 10 pairs of bent axles of supporting roller axially and radial location, starting lathe just can carry out bent axle microcephaly axle journal fillet and carry out rolling and processing.
The present invention can pass through or adopt existing techniques in realizing without the technical characterictic of describing; Repeat no more at this; Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention also is not limited in above-mentioned giving an example; Variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present invention also should belong to protection scope of the present invention.
