Abstract
The utility model discloses a coaxiality machining device which sequentially comprises an adjustable mandrel, an ejection nut, an expansion sleeve, an open washer and a compression nut from the left to the right. The adjustable mandrel is matched with a taper hole of a spindle of a lathe; a plurality of grooves are formed in an outer circle of the ejection nut to bring convenience for detaching a part; six grooves are uniformly formed in the circumference of the expansion sleeve. The left end of the adjustable mandrel has No.6 Morse taper and is matched with the taper hole of the spindle of the lathe, a required taper joint surface is larger than 80%, and the right end of the adjustable mandrel has 1:10 taper. An inner circle and an outer circle of the expansion sleeve need to be machined simultaneously, the coaxially which is lower than or equal to the diameter of 0.015mm needs to be guaranteed, grinding for an inner hole of the expansion sleeve and taper grinding for the right end of the mandrel need to be carried out simultaneously, and a contact surface is larger than 80%. The coaxiality machining device has the advantages that the coaxiality machining device is simple in structure, quick in clamping alignment, reliable in positioning and convenient to clamp and detach, a direct center positioning effect is realized, the rigidity of the mandrel is improved, and machining deformation is prevented.
Description
[technical field]
The utility model relates to mechanical manufacturing field, relates in particular to a kind of axiality processing unit (plant).
[background technology]
In the prior art, very important high-precision part when bearing holder (housing, cover) is 170 diesel engine gear-boxes, its wall thickness is very thin, has only 4mm thick, internal-external circle concentricity requirement≤diameter 0.015mm.The required precision height, difficulty of processing is big.Technological requirement elder generation roughing inside and outside circle, modified back semifinishing inside and outside circle, last first fine finishining endoporus is again with endoporus location, fine finishining cylindrical.Just begun all be the operator from axle of car, generally all being car bumps zero to zero, earlier interior hole dimension is measured in advance, performs record.The big slightly axle sleeve of processing locating hole, the slightly little axle sleeve of reprocessing locating hole.Fit clearance is big slightly, will produce defective work, requires operator's technical merit height, and quality assurance is unreliable, waste product often occurs, and each machining bearing cover is all wanted the car axle, bothersome effort.
[summary of the invention]
At the shortcoming of prior art, it is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, and locatees reliable axiality processing unit (plant).
The technical solution adopted in the utility model is: a kind of axiality processing unit (plant) is characterized in that: comprise ejecting nut by expansion mandrel expansion set, open washer and clamp nut from left to right successively; Wherein expansion mandrel cooperates with the lathe spindle taper hole; Eject and leave several grooves, part for convenience detach on the nut cylindrical; The uniform six road grooves of opening on the circumference of expansion set.
Further, the left end of expansion mandrel is No. 6 taperings of Mohs, cooperates with the lathe spindle taper hole, requires the tapering composition surface greater than 80%, and right-hand member has the tapering of a 1:10.
Further, the expansion set inside and outside circle needs processing simultaneously, guarantees axiality≤diameter 0.015mm, and endoporus should grind with axle right-hand member tapering, and contact-making surface is greater than 80%.
The beneficial effects of the utility model are: simple in structure, direct centralized positioning, and it is rapid to clamp centering, and the axle rigidity increases, and avoids machining deformation, and the location is reliable, and the clamping convenient disassembly.

[specific embodiment]
Referring to accompanying drawing, a kind of axiality processing unit (plant) of the utility model is characterized in that: comprise ejecting nut by expansion mandrel expansion set, open washer and clamp nut from left to right successively; Wherein expansion mandrel cooperates with the lathe spindle taper hole; Eject and leave several grooves, part for convenience detach on the nut cylindrical; The uniform six road grooves of opening on the circumference of expansion set.
Further, the left end of expansion mandrel is No. 6 taperings of Mohs, cooperates with the lathe spindle taper hole, requires the tapering composition surface greater than 80%, and right-hand member has the tapering of a 1:10.
Further, the expansion set inside and outside circle needs processing simultaneously, guarantees axiality≤diameter 0.015mm, and endoporus should grind with axle right-hand member tapering, and contact-making surface is greater than 80%.
Expansion mandrel, one is that centering is convenient, fast in the insertion lathe spindle taper hole, because directly centralized positioning, it is rapid to clamp centering, saves time; The 2nd, increase the axle rigidity, it is indeformable to add man-hour, and the location is reliable.
Eject nut, its effect is when unloading part, because part is difficult to lift down after the swelling, ejects part by it.Convenient in order to unload workpiece, leave several grooves at the nut cylindrical, use the eave tile spanner can unload workpiece easily.
One of expansion set vital part, requirement on machining accuracy comes, and inside and outside circle needs processing simultaneously, guarantees axiality≤diameter 0.015mm, and endoporus should grind with axle right-hand member tapering, and contact-making surface is greater than 80%, for distending uniform six road grooves of opening on circumference.It has two important function, and the one, behind the distending, eliminate the gap, location, the 2nd, also clamping work pieces simultaneously behind the distending.
Open washer, the protection workpiece avoids damaging by pressure workpiece, uses open washer can twist nut and directly takes out workpiece, saves the time of unloading part.
Clamp nut mainly is in order to compress part, to avoid part loosening.A whole set of tool structure compactness, clamping is rapid, unloads conveniently, and the location is reliable.
At this preferred embodiment that this utility model has been described, comprise that the inventor is used to implement known optimal mode of the present utility model.The change of preferred embodiment is apparent for those of ordinary skills after reading above-mentioned explanation.The inventor wishes the change that the those of ordinary skill rational Application is such, and the inventor thinks and offers some clarification on different application at this and also can realize the utility model.Therefore, the utility model comprises all modifications and the equivalents of the purport of quoting in the claim of enclosing, and this allows in the law that is suitable for.In addition, any combination of all possible change of above-mentioned key element is also comprised by the utility model, unless point out in addition or obvious contradiction in context at this.
