The utility model content
The purpose of this utility model is to provide a kind of ultralong deep hole roll extrusion special-purpose milled head.Milled head compact conformation of the present utility model, reasonable shows that through long-term the use it is easy to adjust, no job failure, and the life-span is long, and the efficient height maintains simply, and rolling technology requires to be easy to guarantee.
In order to reach above-mentioned purpose, solution of the present utility model is:
The special-purpose milled head of a kind of ultralong deep hole roll extrusion comprises axle, is set with retainer, first splicing sleeve, second splicing sleeve on the described axle successively and adjusts cover; Described being positioned on the retainer axle before is equipped with roller; Be set with the fender bracket end cap on the axle before the roller; On the axle before the fender bracket end cap first locking nut is installed; Adjust on the cover axle afterwards second locking nut is installed.
First ball and spring are installed between described retainer and the axle successively.
Also be set with the 3rd splicing sleeve on the axle between described first ball and the spring, and spring one end and the 3rd splicing sleeve be connected, the other end and first splicing sleeve are connected.
Between described first splicing sleeve and second splicing sleeve second ball is installed.
On the axle between described second splicing sleeve and the adjustment cover stop pin is installed.
The beneficial effects of the utility model are: the steel part deep hole that wearability is had relatively high expectations, the feed cylinder endoporus of lathe for example, carrying out rolling and processing is the whole processing method of endoporus commonly used in the engineering reality, its leading operation adopts the special reamer fraising usually, the geometric accuracy of hinge back endoporus meets design requirement, the purpose of roll extrusion mainly is to make endoporus surface strengthening, sclerosis by plastic deformation processing, thereby improves its wearability.For satisfying the arts demand of ultralong deep hole rolling and processing, the milled head that the utility model has designed a kind of special use has compact conformation, reasonable, shows through long-term the use, it is easy to adjust, no job failure, and the life-span is long, the efficient height, maintenance is simple, and rolling technology requires to be easy to guarantee.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the special-purpose milled head of a kind of ultralong deep hole roll extrusion comprises axle 11, is set with retainer 3, first splicing sleeve 5, second splicing sleeve 6 on the described axle 11 successively and adjusts cover 9; Described being positioned on retainer 3 axle 11 before is equipped with roller 2; Be set with fender bracket end cap 1 on the axle 11 before the roller 2; On the axle 11 before the fender bracket end cap 1 first locking nut 14 is installed; Adjust on cover 9 axle 11 afterwards second locking nut 14 is installed, and tighten locking nut 14.First ball 13 and spring 4 are installed between described retainer 3 and the axle 11 successively.Also be set with the 3rd splicing sleeve 12 on the axle 11 between described first ball 13 and the spring 4, and spring 4 one ends and the 3rd splicing sleeve 12 be connected, the other end and first splicing sleeve 5 are connected.Between described first splicing sleeve 5 and second splicing sleeve 6 second ball 7 is installed.First ball 13 and second ball 7 by lubricating grease (butter) sequence preface be installed in axle 11 around.On the axle 11 between described second splicing sleeve 6 and the adjustment cover 9 stop pin 8 is installed.First splicing sleeve 5, second splicing sleeve 6, the 3rd splicing sleeve 12 radially by axle 11 supportings, should have than precise gaps with axle 11 to cooperate.The supporting end face of first splicing sleeve 5, second splicing sleeve 6, second ball 7 should have the flatness requirement, with separately endoporus better perpendicularity should be arranged, and second ball 7 should have dimensional uniformity preferably, the axial stability when guaranteeing the gyration of this position.Use grease lubrication when second ball 7,13 work of first ball, use oil lubricating during roller work.Splicing sleeve 6 and the junction of adjusting cover 9
bCorresponding dial is set, with expression scale amount of spin
Δ lWith the roller peak (
aPoint) tactical diameter increment
Δ dBetween relational expression:
In the formula,
Δ dFor
aThe spot diameter increment,
nBe rotation scale lattice number,
Δ l n Be every lattice amount of movement,
a Be tap web 1/2 cone angle.The preceding end mill of retainer 3 (copper sheathing) is logical, and the bottom should be spherical, and guarantee each ball lower shaft to contour accurately and with the contact of roller end points, to guarantee each roller
aPoint is isometrical.Roller 2 should carry out many selected groupings, with the good uniformity of assurance diameter dimension, tapering, and carries out meticulous surface finish.The tapering that axle 11 cooperates with roller 2 should guarantee good tapering precision, wearability, contact rate, and guarantee to have behind the equipped roller 2 0.5 ° feeding along awl, opposite with direction of feed to guarantee roll extrusion power, roller 2 inverted orientation are stable, avoid occurring roller 2 feeding motilities.Adjust 9 pairs of roller 2 peaks of cover
aThe adjustment amount of tactical diameter
Δ dShould be controlled in 0.5～0.6mm scope, unsuitable excessive, surmount normal mill zone otherwise can cross ambassador's roller because of roll adjustment, cause the adjustment distortion.Retainer 3 (copper sheathing) and each driving member outside diameter should be all the time less than roller 2 tactical diameters and processed diameter of bores, to guarantee the milled head operate as normal.
The utility model is adjusted cover 9 by second locking nut 10, adjust roller 2 by the squeezing action of adjusting cover 9, when adjustment cover 9 is adjusted left, (in 0.12～0.15mm) scope, lock by locking nut 10 then at the roll extrusion magnitude of interference of regulation until the peak of roller 2.Thereby be expressed to second splicing sleeve 6, second splicing sleeve 6 acts on first splicing sleeve 5 again then, first splicing sleeve 5 passes to power retainer 3 again, 2 effects of 3 pairs of rollers of retainer, because roller 2 is conical, so roller 2 can move up and down under the effect of external force, thereby realize the roll extrusion effect in the hole of different sizes.During feeding, roller 2 roll extrusion bore areas, retainer end cap 1, retainer 3, spring 4, first splicing sleeve 5, the 3rd splicing sleeve 12 and 11 rotations of roller 2 locking phase center rollers, its revolving force is from the thrust backward of roller 2.Roller 2 both phase center roller 11 conical surfaces rolls, and surface of the work rolls relatively simultaneously; Make axial rolling bearing with each part that roller 11 rotates synchronously by second ball 7, first ball 13.Feeding finishes the withdrawing of pulling back after (roller 2 rolls out), and in 4 compressions of pull-back forces effect lower spring, roller 2 retreats to the tap web microcephaly, and external diameter shrinks, and returns the circulation of finishing the work smoothly.The milled head compact conformation of present embodiment, reasonable shows that through long-term the use it is easy to adjust, no job failure, and the life-span is long, and the efficient height maintains simply, and rolling technology requires to be easy to guarantee.
