Abstract
The utility model provides a kind of combined type self-centering swelling fixture that can position clamping for the locating hole of different size, comprise spring expansion sleeve and quick-replaceable opening sleeve, quick-replaceable opening sleeve is a hollow cylinder, described hollow cylinder is provided with the wide adjustment seam of 1-6mm along generatrix direction, described quick-replaceable opening sleeve can be enclosed within spring expansion sleeve and with spring expansion sleeve interference fits.This quick-replaceable opening sleeve low cost of manufacture, can produce the quick-replaceable opening sleeve of different size according to different workpiece; It is convenient to change, and only needs original quick-replaceable opening sleeve to take off, new is put, save unproductive time, improve working (machining) efficiency.
Description
Technical field
The invention belongs to clamping tool for machine work field, be specifically related to a kind of combined type self-centering swelling fixture.
Background technology
At present, in dish, cover class turnery processing, the self-centering spring expansion sleeve widely used as shown in Figure 1 positions clamping.
Use this spring expansion sleeve, when part to be processed is changed, when locating hole size changes, need to change different spring expansion sleeves, spring expansion sleeve is fixed on lathe by multiple screw, and one to carry out replacing construction long, affects working (machining) efficiency, two to carry out spring expansion sleeve manufacturing cost high, and processing charges increases.
Summary of the invention
The utility model object is: provide a kind of combined type self-centering swelling fixture that can position clamping for the locating hole of different size.
Technical solution of the present utility model is:
Combined type self-centering swelling fixture, its special character is, comprise spring expansion sleeve and quick-replaceable opening sleeve, described quick-replaceable opening sleeve is a hollow cylinder, described hollow cylinder is provided with the wide adjustment seam of 1-6mm along generatrix direction, described quick-replaceable opening sleeve can be enclosed within spring expansion sleeve and with spring expansion sleeve interference fits.
The material of above-mentioned quick-replaceable opening sleeve is spring steel.
The inwall of above-mentioned quick-replaceable opening sleeve is the conical surface near upper and lower both sides.
Above-mentioned spring expansion sleeve comprises base and is fixed on the hollow cylinder body on base, and described hollow cylinder body is provided with 2-8 swelling seam along generatrix direction.
The outer surface of the upper end of above-mentioned swelling seam is the conical surface.
The material of above-mentioned spring expansion sleeve is spring steel.
The utility model has the advantages that: (1) quick-replaceable opening sleeve low cost of manufacture, the quick-replaceable opening sleeve of different size can be produced according to different workpiece.(2) quick-replaceable opening sleeve is changed conveniently, only needs original quick-replaceable opening sleeve to take off, new is put, save unproductive time, improve working (machining) efficiency.(3) setting of the conical surface, when there is the situation of interference fit, quick-replaceable opening also can be easy to be enclosed within spring expansion sleeve.

Detailed description of the invention
Embodiment one: adopt built-up jig mode, devise quick-replaceable opening sleeve and spring expansion sleeve as shown in Figure 2, quick-replaceable opening sleeve is a hollow cylinder 1, described hollow cylinder 1 is provided with the wide adjustment seam 2 of 1-6mm along generatrix direction, this quick-replaceable opening sleeve can be enclosed within spring expansion sleeve and with spring expansion sleeve interference fits.
Spring expansion sleeve comprises base 5 and is fixed on the hollow cylinder body 3 on base 5, and hollow cylinder body 3 is provided with 2-8 swelling seam 4 along generatrix direction.The base of spring expansion sleeve is provided with some screwed holes, for spring expansion sleeve entirety being fixed on lathe with screw fit.
The material of quick-replaceable opening sleeve is spring steel.The material of spring expansion sleeve is spring steel.
Using method, is fixed on lathe by spring expansion sleeve, when part to be processed is changed, when locating hole size changes, the quick-replaceable opening sleeve of suitable thickness is selected to be enclosed within spring expansion sleeve, when expansion sleeve swelling, quick-replaceable opening sleeve also follows distending, serves the effect of location clamping.
Embodiment two: as Fig. 3, the basis of embodiment one is improved, and the inwall of quick-replaceable opening sleeve is the conical surface 6 near upper and lower both sides.The outer surface of the upper end of swelling seam is the conical surface.
Owing to being interference fits between quick-replaceable opening and spring expansion sleeve, the situation of interference fit when being overlapped on spring expansion sleeve by quick-replaceable opening, may be there is, the conical surface be arranged so that quick-replaceable opening is more easily enclosed within spring expansion sleeve.As long as quick-replaceable opening sleeve and spring expansion sleeve two parts have a place to be provided with the conical surface.
