Background technology
Bowlder outside the rotor of turning silicon steel sheet material compacting on lathe, because workpiece is to adopt that many silicon steel sheets are compressed together to be made, and this type of workpiece processed workpiece surface roughness requires extremely low, adopt universal cutter to process above-mentioned surface of the work cylindrical and then be difficult to guarantee the workpiece crudy, this is because the initial surface roughness is poor before the workpiece processing, cutting surface size and accuracy of form and position error are jumped bigger, thereby cutter is in the interrupted cut state all the time in the cylindrical turning process, the influence that is subjected to inhomogeneous cutting force and beats, the machining accuracy of workpiece, all be difficult to the service life of working (machining) efficiency and cutter satisfy efficient, high-quality processing request.
Summary of the invention
The purpose of this utility model is to propose a kind of circular tool that is used to process rotor.Can make machined surface obtain high machining accuracy, both can satisfy the needs of outer round surface machining accuracy, also can greatly improve working (machining) efficiency.Have simple in structure, make easily, the hardness height, toughness is better, the characteristics of long service life.
The utility model realizes that the technical scheme that above-mentioned purpose is taked is: it is by locking nut, pad, cylinder blade, cutter hub, axle, end ring, bearing, pad, bearing cap, spacing back-up ring, stay and two locking nuts are formed, cylinder blade adopts the interference fit tolerance to be sleeved on the axle one side cylindrical, this cylinder blade one side end face is by putting down on axial region shaft shoulder plane of orientation, the axial pressing force that is formed by two locking nuts and pad is pressed on cylinder blade on the axle, two single-row tapered roller bearing symmetries are sleeved on the axle that is positioned at cutter hub, the inner ring of these two single-row tapered roller bearings is an interference fit with axle, the endoporus of outer ring and cutter hub is an interference fits, by locking nut two bearings are fastened on the axle, also are about to cutter hub and are assembled into one with axle.
The utility model adopts the combination technological method processing rotor cylindrical of turning-roll extrusion in turning process, thereby can make machined surface obtain high machining accuracy, and because cutter can rotate with workpiece in working angles, therefore the radiating condition of cutter is better, in turning process, can adopt higher cutting speed, both can satisfy the needs of outer round surface machining accuracy, and also can make working (machining) efficiency and cutter life obtain to improve greatly.Have simple in structure, make easily, the characteristics that result of use is good, working (machining) efficiency can improve more than the several times, owing to adopt the carbide alloy disk, thereby have the hardness height, toughness is better, the characteristics of long service life.Be applicable to that the disc type carbide alloy that processing adopts silicon steel sheet (or similar steel disc material) material to suppress the rotor cylindrical that forms pushes turning cutting tool.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Among the figure: 1, locking nut, 2, pad, 3, cylinder blade 4, cutter hub, 5, axle, 6, end ring, 7, bearing, 8, pad, 9, bearing cap, 10, spacing back-up ring, 11, stay 12, locking nut.
The specific embodiment
In conjunction with the accompanying drawings, it is as follows to provide specific embodiment of the utility model:
As shown in Figure 1, present embodiment is made up of locking nut 1, pad 2, cylinder blade 3, cutter hub 4, axle 5, end ring 6, bearing 7, pad 8, bearing cap 9, spacing back-up ring 10, stay 11, locking nut 12.Cylinder blade 3 adopts the interference fits tolerance to be sleeved on the axle 5 one side cylindricals, and blade installation location is realized by putting down in cylinder blade 3 one side end faces on 5 shaft shoulder plane of orientations of axle, and the mode by screw threads for fastening, the axial pressing force that adopts two locking nuts 1 and pad 2 formation is with on cylinder blade 3 fastener shafts 5, because cylinder blade 3 has adopted between 5 circumference to lock and two kinds of clamping modes of axial compression with axle, thereby it is all very easy to have the installing/dismounting of antislip performance preferably and blade between cylinder blade 3 fastener shafts 5.Cylinder blade 3 materials adopt whole YT14 carbide alloy, thereby have higher wearability and certain toughness, can effectively guarantee at working angles the requirement of cutter wearability and the impact resistance requirement of interrupted cut.Cutter hub 4 materials are 45 steel, are HRC26-32 through modifier treatment hardness.The axle 5 materials be 40Cr, hardness is HRC40～42 after the heat treatment, is designed to tetragonal structure, with easy to setup on lathe cutter saddle.Each locating surface all adopts grinding to handle on the axle.Two single-row tapered roller bearings 7 are sleeved on symmetric mode as pivoted member and reach in the cutter hub 4 on the axle 5, adopt interference fit between its middle (center) bearing 7 inner rings and the axle 5, bearing 7 outer rings and cutter hub 4 endoporus are the interference fits mode, after guaranteeing that bearing is installed, bearing 7 inside and outside circles can not produce slip relatively at axle 5 and cutter hub 4.This kind mounting arrangement mode can be born in working angles because of cutting force acts on bigger radial load and axial load on the cutter, thus when satisfying turning-extruding compound technology to the performance need of cutter rigidity and vibration resistance.Be provided with end ring 6 between the outer ring of two single-row tapered roller bearings 7, play compartmentation, bearing cap 9 is sleeved in cutter hub 4 endoporus, its left surface and the side snap of bearing 7 outer ring.Spacing back-up ring 10 is sleeved on the axle 5, and its left surface and bearing 7 inner ring side snaps limit bearing 7 outer rings and move axially.In the arranged outside of single-row tapered roller bearing 7 by the locking device of forming by bearing cap 9, spacing back-up ring 10, stay 11 and locking nut 12, tighten that two locking nuts 12 and stay 11 promotes bearing caps 9, spacing back-up ring 10 can be fastened on two bearings 7 on the axle, also be about to cutter hub 4 and be assembled into one with axle 5.Because cylinder blade 3 can roll in cutter hub 4 with axle 5, the outer bowlder of cutting workpiece, under the effect of cutting force, be fastened on that cylinder blade 3 just rotates simultaneously in company with being cut workpiece on the axle 5, make cylinder blade 3 whole circumference cutting edges participate in cutting in the continuous rolling mode of going forward one by one, and constantly rotate cutting zone and cool off, therefore the blade radiating condition is better, helping cutter life prolongs, thereby stock-removing efficiency is significantly improved, and this type of adopts the needs of steel disc compacting workpiece high precision excircle to satisfy highly-efficient processing.The benefit that adopts single-row tapered roller bearing 7 and symmetry to install is: when cutter at cutting workpiece and produce when rotating at a high speed, can bear because of cutting force and act on bigger radial load and axial load on the cutter, thereby make cutter have rigidity and vibration resistance preferably, can guarantee that each depth of cut is about 1mm, to guarantee the requirement of workpiece machining accuracy and working (machining) efficiency.
During use, this cutter is pressed on the lathe cutter saddle, and make center cutter line and machine axis be 15～20 ° inclination, in the working angles under the effect of cutting force, the rotary speed of cutter will be different with the variation of above-mentioned mounted angle, the big more then rotating speed in inclination angle is high more, thereby being rolled successively, cylinder blade 3 whole circumference cutting edges participate in cutting, the comparable universal cutter of cutter life improves more than tens of times, owing in turning process, have the rolling technology effect, thereby can obtain high surface accuracy, and can effectively improve the anti-fatigue performance of rotor.
