Abstract

A kind of anti-annular thin wall part deformation processing fixture, comprises the clamping part and axle with integrative-structure; The axial line of described clamping part overlaps with the axial line of axle; The shaft shoulder is provided with between described clamping part and axle; Described axle is circumferentially with flexible expansion ring; The diameter of described axle is less than the inner ring diameter before annular thin wall part processing; Described flexible expansion ring is less than axle axial length along the width of axle axis.The utility model reduces the deformation quantity of annular thin wall part, improves processing progress.Axle also has certralizing ability, improves the axiality of annular thin wall part.Meanwhile, the utility model is structure as a whole, and can disposablely be clamped on lathe, fast convenient and time-saving.

Description

A kind of anti-annular thin wall part deformation processing fixture

Technical field

The utility model relates to a kind of fixture, is specifically related to a kind of anti-annular thin wall part deformation processing fixture.

Background technology

At present, the processing of thin-walled parts becomes a difficult problem for numerous mechanic factory workers.Now produce that annular thin wall part is many clamping to lathe to be processed after Wetted constructures again.Fixture used mostly is chuck mode clamping, and the rigidity of thin-walled parts self is not enough, and flexibility is had a surplus, and the point of application because of the clamping force of chuck is uneven very easily produces deformation, and difficulty of processing is large.The error of the annular thin wall part machined is 3 ~ 5, with technical requirement≤2 there is gap.

Utility model content

The purpose of this utility model aims to provide a kind of anti-annular thin wall part deformation processing fixture, and to solve above-mentioned annular thin wall part generation deformation, fixture clamping expends time in long problem.

For achieving the above object, the utility model adopts following technical scheme:

A kind of anti-annular thin wall part deformation processing fixture, is characterized in that: comprise the clamping part and axle with integrative-structure; The axial line of described clamping part overlaps with the axial line of axle; The shaft shoulder is provided with between described clamping part and axle; Described axle is circumferentially with flexible expansion ring; The diameter of described axle is less than the inner ring diameter before annular thin wall part processing.

In such scheme, described flexible expansion ring is less than axle axial length along the width of axle axis.

Because technique scheme is used, the utility model compared with prior art has following advantages:

The one that the utility model provides anti-annular thin wall part deformation processing fixture, effectively can disperse clamping force, make annular thin wall part uniform force, can reduce the possibility of workpiece deformation.Meanwhile, axle also has certralizing ability, improves the axiality of annular thin wall part.And this fixture processing technology is simple, is structure as a whole, is convenient to producing shaped, be convenient to be clamped on lathe, the clamping time is very fast, and production efficiency is higher.

Fig. 2 is cross-sectional view of the present utility model;

Fig. 3 is the view after the utility model clamping annular thin wall part;

In above accompanying drawing: 1, clamping part; 12, the shaft shoulder; 2, axle; 3, flexible expansion ring.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is further described:

Shown in Fig. 1, Fig. 2: a kind of anti-annular thin wall part deformation processing fixture, is characterized in that: comprise the clamping part 1 and axle 2 with integrative-structure; The axial line of described clamping part 1 overlaps with the axial line of axle 2; The shaft shoulder 12 is provided with between described clamping part 1 and axle 2; Described axle 2 is circumferentially with flexible expansion ring 3; The diameter of described axle 1 is less than the inner ring diameter before annular thin wall part processing.

Preferably, described flexible expansion ring 3 is less than axle 2 axial length along the width of axle 2 axis.

Shown in Figure 3: during production, installed to by crude annular thin wall part on axle 2 position of fixture, axle 2 and flexible expansion ring 3 embed in thin-wall part, and one end that thin-wall part contacts with axle 2 props up clamping part 1, both are welded and fixed, and then clamping to lathe is processed.After machining, cut from the position of corresponding axle 2 end face of annular thin wall part outer wall.Annular thin wall part under cutting is processed finished products, stays remaining annular thin wall part clout in axle 2 to be then removed.The axle 2 eliminating clout again clamping annular thin wall part is processed again.

The processing characteristic larger according to annular class thin-wall part clamping deformation amount, the machining accuracy of thin wall work-piece often depends on fixture, and the processing of fixture to thin-wall part plays a decisive role.The utility model reduces the deformation quantity of annular thin wall part, improves processing progress.The clamp for machining that the utility model provides also has certralizing ability, improves the axiality of annular thin wall part.Meanwhile, this fixture clamping is simple and convenient, and disposable clamping completes and saves time.

Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model change or modify, and all should be encompassed within protection domain of the present utility model.
