Abstract
The invention discloses a machine tool fixture for machining sleeve parts, which comprises a mandrel mounted in a machine tool spindle hole. A boss is arranged in the middle of the mandrel, an expansion sleeve is mounted at the other end of the mandrel, a pull rod is arranged in a through hole of the mandrel, the other end of the pull rod is connected with a tensioning core and a locking nut in a threaded manner, the expansion sleeve is of a split structure with a radially trisected expansion sheet, two spring rings are mounted on the outer surface of the expansion sleeve, a groove I is arranged on the inner side of the expansion sleeve, a groove II is arranged on the outer surface of the tensioning core, and the groove II and the groove I are mutually embedded. The machine tool fixture has the advantages of simple structure, convenience in operation and high positioning precision.
Description
Technical field
The present invention relates to a kind of jig, relate in particular to a kind of jig that is used to type of overlapping, thin-walled cover class, cylinder parts processing.
Background technology
In machine components processing; Can touch the processing of a lot of cover parts, some cover parts is very high for the required precision of processing, when often passing through common scroll chuck clamping workpiece; Can not satisfy position accuracy demand; And making workpiece produce moderate finite deformation, the precision of influence processing causes workpiece to be scrapped.For the processing of part cover parts, use traditional scroll chuck can not satisfy the demand of production and processing.
Summary of the invention
The present invention is in order to overcome the defective of prior art, is to provide a kind of simple in structure, easy to operate, jig that is used for cover parts processing that positioning accuracy is high.
Technical scheme of the present invention is: a kind of jig that is used for cover parts processing; Comprise be installed in the machine tool chief axis hole mandrel; Described mandrel mid portion is provided with boss; The other end of described mandrel is installed the swelling cover, in the through hole of described mandrel, is provided with pull bar, and the other end of described pull bar is installed tension core and locking nut through being threaded.
Wherein, the inner surface of the opposite side outer surface of described mandrel and described swelling cover is cone match.
Wherein, described swelling cover is that radially the swelling sheet of trisection divides body structure, at the outer surface of described swelling cover two turns is installed, and is provided with in the inboard of described swelling cover and colludes the groove I.
Wherein, be provided with at the outer surface of described tension core and collude the groove II, describedly collude the groove II and the described groove I of colluding embeds each other.
A kind of jig that is used for cover parts processing of the present invention has advantage simple in structure, easy to operate, that positioning accuracy is high owing to adopted above technical scheme.
Description of drawings
Fig. 1 is a kind of structural representation that is used for the jig of cover parts processing of the present invention.
Fig. 2 is the cross-sectional view of A-A among Fig. 1.
Among the figure: the 1-mandrel; 2-swelling cover; 21-swelling sheet; The 3-boss; The 4-pull bar; 5-strains core; The 6-locking nut; The 7-turn; 81-colludes the groove I; 82-colludes the groove II; The 9-workpiece.
The specific embodiment
See also Fig. 1 and Fig. 2; The invention provides a kind of jig that is used for cover parts processing, comprise be installed in the machine tool chief axis hole mandrel 1, mandrel 1 mid portion is provided with boss 3; Can play effect with the workpiece location; The other end of mandrel 1 is installed swelling cover 2, in the through hole of mandrel 1, is provided with pull bar 4, and the other end of pull bar 4 is installed tension core 5 and locking nut 6 through being threaded.
Wherein, the inner surface of the opposite side outer surface of mandrel 1 and swelling cover 2 is cone match.
Wherein, swelling cover 2 is 21 fens body structures of swelling sheet of radially trisection, at the outer surface of swelling cover 2 two turns 7 is installed, and is provided with in the inboard of swelling cover 2 and colludes groove I 81.
Wherein, be provided with and collude groove II 82, collude groove II 82 and collude groove I 81 and embed each other at the outer surface of tension core 5.
In practical operation; When sleeve workpiece 9 is installed in the outer round surface of swelling cover 2; With swelling cover 2 side tension inwards, the outer round surface of swelling cover 2 radially becomes greatly through pull bar 4, because of turn 7 produces compression stress; And because of workpiece 9 radial load in process guarantees the sleeve workpiece 9 fastening outer round surface that are installed in swelling cover 2 more greater than axial force; When needs are changed sleeve workpiece 9, only need a loose lower locking nut 6 to get final product.
A kind of jig that is used for cover parts processing of the present invention has advantage simple in structure, easy to operate, that positioning accuracy is high owing to adopted above technical scheme.
What should explain at last is: above embodiment only in order to the explanation the present invention and and unrestricted technical scheme described in the invention; Therefore, although this specification has carried out detailed explanation to the present invention with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the present invention; And all do not break away from the technical scheme and the improvement thereof of the spirit and scope of the present invention, and it all should be encompassed in the claim scope of the present invention.
