Abstract
The utility model discloses a kind of fixture of taper inner hard alloy pressed compact processing excircles, and its structural relation is：Supporting with spring chuck body inside taper core bar insertion spring chuck body, ER type elastic collet chucks are enclosed on taper core bar, and round nut pressure cap is screwed on spring chuck body, complete the assembling of fixture, and its advantage is：It is small hole size can be processed, and the hard alloy pressed compact with taper, it is effectively guaranteed the concentricity and crudy of pressed compact, improve clamping efficiency and product quality, in addition, the clamping diameter of the spring chuck can adjust within the specific limits, and taper core bar is replaceable, realize that a sleeve clamp processes the hard alloy pressed compact product of multiple endoporus.
Description
Technical field
It the utility model is related to a kind of fixture, and in particular to a kind of folder of taper inner hard alloy pressed compact processing excircles
Tool.
Background technology
ER elastic collet chucks are also known as high precision elastic chuck, accurate collet chuck, because its stable performance, precision is high, handling are simple and
It is widely used in drilling machine, milling machine, attacks in the equipment such as bed, machining center, attacks milling cutter for confining brill, and fixed locking adds
Work part.Hard alloy uses the mode of production of powder metallurgy, and its compact strength is low, and clamping and processing are also easy to produce breach, crackle,
Even it is broken.For the hard alloy pressed compact with the small endoporus of taper, if wanting processing excircles, added with endoporus positioning and clamping difficulty
Greatly, and it is difficult to ensure that endoporus and cylindrical concentricity.The utility model can avoid shortcoming caused by above manufacturing process, and energy
Enough process the product of meet demand.
Utility model content
The purpose of this utility model is just to provide a kind of fixture of taper inner hard alloy pressed compact processing excircles, for solving
Certainly the product improves processing efficiency the processing excircles on numerically controlled lathe the problem of, ensures product quality.
The technical solution of the utility model is：A kind of fixture of taper inner hard alloy pressed compact processing excircles, main bag
Include：Spring chuck body, taper core bar, ER types elastic collet chuck, round nut pressure cap；Inside taper core bar insertion spring chuck body
Supporting with spring chuck body, ER type elastic collet chucks are enclosed on taper core bar, and round nut pressure cap is screwed on spring chuck body.
Spring chuck body described in the utility model is one section of cylinder for having stepped throughhole, spring chuck body outer end table
There is screw thread in face.The inverted cone surface of spring chuck body and ER type elastic collet chucks coordinates, and spring chuck body and round nut pressure cap
Screw thread mating reaction under, realize the clamping to hard alloy pressed compact.
Taper core bar described in the utility model is a tapered stepped cylinder, can be processed with taper inner
Cylindrical product；Taper core bar can be changed according to the internal via shape of converted products, and hard alloy pressure is positioned using taper core bar
The inward hole slope of base, small endoporus core bar clamping hardly possible is avoided, is beated the problem of big.
ER types elastic collet chuck described in the utility model is the inverted cone surface cylinder of one section of through hole, and ER elastic collet chucks can be according to processing
Standard component corresponding to the size selection of product, realize sleeve clamp processing more similar hart metal products.
Round nut pressure cap described in the utility model is U-shaped that can be a spacing nut, can be fast by twisting round nut pressure cap
The handling to hard alloy pressed compact are realized fastly, are made the radially uniform stress of clamped product, be ensure that cylindrical and endoporus concentricity.
Effect of the present utility model is：Using the utility model, can turnery processing hole size it is small, and the hard with taper
Alloy pressed compact, the concentricity and crudy of part are effectively guaranteed, improves clamping efficiency and product quality；The practicality is new
The problems such as type is simple in construction, easy to assembly, solves the bad clamping of endoporus, and the efficiency of loading and unloading is slow；It need to only add in use
Before work hard alloy pressed compact, the concentricity of clamping fixture for correcting, automatic centering can be realized in subsequent clamping pressed compact, without going to school again
The concentricity of positive pressed compact.
Brief description of the drawings
Fig. 1 is overall structure figure of the present utility model.
Fig. 2 is the design sketch that hard alloy pressed compact is processed using the utility model.
Fig. 3 is the design of part figure before processing.
Fig. 4 is the design sketch after the fixture processing using the utility model taper inner hard alloy pressed compact processing excircles.
In figure, spring chuck body（1）, taper core bar（2）, ER type elastic collet chucks（3）, round nut pressure cap（4）, it is to be added
Work hard alloy pressed compact（5）, billmpse tool（6）.
Embodiment
Embodiment of the present utility model is described in further detail below in conjunction with brief description of the drawings, but the present embodiment and not had to
It is every to use similar structure of the present utility model and its similar change in limitation the utility model, the utility model all should be included in
Protection domain.
As shown in figure 1, the utility model is such to work, a kind of taper inner hard alloy pressed compact processing excircles
Fixture, mainly include：Spring chuck body（1）, taper core bar（2）, ER type elastic collet chucks（3）, round nut pressure cap（4）；It is special
Sign is：Taper core bar（2）Insert spring chuck body（1）The inside and spring chuck body（1）It is supporting, ER type elastic collet chucks
（3）It is enclosed on taper core bar（2）On, round nut pressure cap（4）It is screwed in spring chuck body（1）On.
First by taper core bar（2）Mounted in spring chuck body（1）Above, ER type elastic collet chucks are put（3）, then will circle
Nut pressure cap（4）It is screwed in spring chuck body（1）On, complete the assembling of fixture.In clamping, by round nut pressure cap（4）Unclamp,
Make ER type elastic collet chucks（3）Endoporus swells, and then ensures axiality within 0.05mm with amesdial clamping fixture for correcting, will be to be processed
Hard alloy pressed compact（5）It is enclosed on taper core bar（2）On, and it is inserted into ER type elastic collet chucks（3）It is interior, then tighten round nut pressure cap
（4）, but it is excessive in order to avoid pressed compact to be processed to exert oneself（5）By ER type elastic collet chucks（3）Folder splits, then again by billmpse tool（6）
On knife rest, it is ensured that point of a knife point slightly below treats half pressurization base（5）The centre of gyration, and with amesdial correction lathe tool handle of a knife ensure
The perpendicularity of the centre of gyration of lathe tool and pressed compact is within 0.01mm, the operation according to the requirement of processing dimension according to numerically controlled lathe
Specification, turnery processing is carried out to product.After the completion of turning, unscrew round nut pressure cap（4）, the hard alloy pressure after machining
Base（5）Take out.
