Description
Technical field
The present invention relates to the processing method of thin-walled parts, particularly a kind of method for fine finishing of two half-watt thin-wall bushes and device thereof.
Background technology
Two half-watt thin-wall bushes are arranged in the roughing mill live-roller bearing block of strip-mill strip, are used for supporting roughing mill transmission shaft of working roll and regulate the angle of power transmission shaft, thus provide transmission accurate operation power for milling train.
As shown in Figure 1, the cylindrical of two half-watt thin-wall bush parts is steel body, inwall and the bonding babbit of both ends of the surface, and after turning, Linear cut is two half-watts (as shown in Figure 2).Lining inside and outside circle requires axiality 0.05mm, inner circle roughness requirements R
a1.6 μm.Because two half-watt pairings use, so two half-watts need processing in pairs during fine finishining.Usually two kinds of processing methods are had, the first scheme: first by two half-watt bushing combination, in the spot welding of flange excircle place, fallen by crator car after fine finishining again.Because the rigidity of two half-watt parts own is poor, and larger clamping force retaining element need be used man-hour adding, therefore cause lining finishing post-construction deformation excessive (deflection is within the scope of 0.3 ~ 0.4mm), and inside and outside circle decentraction, can not meet designing requirement.First scheme: first the flange excircle clip of two half-watt linings after combination is fixed, then push down part end face with ring flange, precision-machined parts cylindrical.Because clip circularity is poor, firmly after banding, lining is unbalance stress circumferentially, causes excircle of bushing to be out of shape comparatively large, cannot meet the technical requirement of lining under the effect of chip power.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, provide a kind of method for fine finishing and device thereof of two half-watt thin-wall bushes, after solving existing lining fine finishining, part deformation is excessive, the technical problem of inside and outside circle decentraction.
The present invention is achieved by the following technical solutions:
A method for fine finishing for two half-watt thin-wall bushes, its concrete steps are as follows:
1. circular mold is installed on vertical grinder chuck, and with chuck centering;
2. by two half-watt thin-wall bush vertically-arrangeds on circular mold, place No. II stifle, No. I stifle successively in two half-watt thin-wall bush upper surfaces;
3. by being arranged on the centering screw in No. II stifle and circular mold outer rim boss counterbore, by the cylindrical centering of two half-watt thin-wall bushes;
4. after centering, draw-in bar is installed, and by No. I stifle, No. II stifle, two half-watt thin-wall bushes is fixed with nut;
5. two half-watt thin-wall bush cylindricals are refined;
6. grinding complete after installation outside link, and two half-watt thin-wall bushes to be fixed by No. II stifle with nut, draw-in bar of dismantling, nut, emery wheel of dismantling;
7. boring head is installed, right boring endoporus;
8. after inside and outside circle machines, by half-watt thin-wall bush and mold integral hoisting on vertical lathe;
9. centering part, draw-in bar of dismantling, nut, No. I stifle, No. II stifle, outside link, and cross through hole on excircle of bushing with nut by outside link the cylindrical of half-watt thin-wall bush is fixed;
10. turning half-watt thin-wall bush end face of flange is to requiring size, and part is reversed end for end, and after centering, another end face of flange of turning half-watt thin-wall bush is to requiring size.
The device that a kind of two half-watt thin-wall bush method for fine finishing adopt, be made up of draw-in bar, nut, No. I stifle, No. II stifle, outside link, centering screw and circular mold, described circular mold 4 bolts and 4 equal height cushion blocks are installed on vertical grinder chuck, described circular mold outer rim has convex platform, vertically-arranged two half-watt thin-wall bush in the convex platform of described circular mold, No. II stifle is placed in the upper surface of described two half-watt thin-wall bushes, and No. I stifle is placed in the upper surface of described No. II stifle; Described No. II stifle outer rim has lower convex platform, gap-contact between described lower convex platform and two half-watt thin-wall bushes, described convex platform, lower convex platform horizontal direction circumferentially distinguish uniform 6 screw holes, be respectively charged into centering screw, described convex platform vertical direction is at least uniform 4 bolts hole circumferentially, described lower convex platform vertical direction is at least uniform 4 through holes corresponding with convex platform bolt hole circumferentially, are respectively charged into outside link, and are fixed by two half-watt thin-wall bushes by No. II stifle with nut; Described No. I stifle vertical direction be at least uniform 4 bolt holes circumferentially, described circular mold vertical direction is at least uniform 4 bolts hole corresponding with the bolt hole of No. I stifle circumferentially, be respectively charged into draw-in bar, and by No. I stifle, No. II stifle, two half-watt thin-wall bushes be fixed with nut.
The present invention compared with prior art, owing to having installed 6 centering screws respectively on circular mold and No. II stifle outer rim boss, can be used for finely tuning centering lining, compare that clip strength is little, registration, and bad mold joint can be alignd, the problem that before solving, the mode of being installed causes part deformation excessive.Meanwhile, install two stifles at part end face, the position of conversion pull bar, both can realize fine cylindrical, also can right boring endoporus, compared with existing processing scheme, had both saved the time of centering, and in turn ensure that the concentricity of the inside and outside circle of part.
