Abstract
The utility model provides an automatic centering expansion tooling for a self step hole, which comprises a mandrel body, a bidirectional press sleeve, a locking screw bolt and an ejecting sleeve, wherein the mandrel body is fixedly arranged on a machine tool spindle, the locking screw bolt is arranged in the mandrel body, the ejecting sleeve is arranged at one end of the mandrel body, a first butterfly-shaped spring leaf is arranged between one end of the bidirectional press sleeve and the mandrel body, a second butterfly-shaped spring leaf is arranged between the other end of the bidirectional press sleeve and the ejecting sleeve, a guide key is fixedly arranged on the ejecting sleeve and is positioned in a key slot of the mandrel body, a support sleeve is arranged between the second butterfly-shaped spring leaf and the ejecting sleeve, a first press plate is arranged between the first butterfly-shaped spring leaf and the mandrel body, and a second press plate is arranged between the second butterfly-shaped spring leaf and the support sleeve. The automatic centering expansion tooling has the advantages that step hole sleeve type parts can be clamped, the problems that a matching gap between a step shaft and a step hole exists, and the deformation is easy to generate due to the clamping of thin wall step hole sleeve type parts can be solved, the clamping is convenient, the processing efficiency is improved, and the cost is reduced.
Description
Technical field
The utility model belongs to mechanical field, relates in particular to a kind of from stepped hole self-centering swelling frock.
Background technology
The processing of stepped hole thin-walled cover parts cylindrical mainly contains two kinds of methods: the one, and grab the direct support of chuck one end endoporus with three and process.Behind this kind clamping; Also want beating of centering other end endoporus and end face, lose time, can't press-fit fast. and because wall thickness approaches workpiece easy deformation when supportting endoporus; Influence the part processing quality; Be prone to waste product. the 2nd, to process a step axle and have the stepped hole matched in clearance of stepped hole thin-walled cover parts, in the other end press-fiting with nut. this kind installation way axle and have between the stepped hole of stepped hole thin-walled cover parts and have the gap influences the axiality between part cylindrical and the stepped hole; And the end face (wall thickness is thinner) of nut extruding is prone to produce distortion, influences crudy.
Summary of the invention
It is a kind of from stepped hole self-centering swelling frock that the utility model provides, solved in the background technology three grab the chuck clamping yielding, need centering other end endoporus and end face run-out shortcoming.
The technical scheme of the utility model is achieved in that a kind of from stepped hole self-centering swelling frock; Comprise the axle body, the two-way gland that are fixedly mounted on the machine tool chief axis, be satisfied with clamping screw and the tight sleeve of axle body one end in the axle body; Be equipped with butterfly spring sheet I between one end of two-way gland and the axle body, be equipped with butterfly spring sheet II between the other end of two-way gland and the tight sleeve;
Fixedly be equipped with feather key on the tight sleeve, feather key is positioned at the keyway of axle body;
Be equipped with support set between butterfly spring sheet II and the tight sleeve;
Be provided with the pressing plate I between butterfly spring sheet I and the axle body, be provided with the pressing plate II between butterfly spring sheet II and the support set.
The beneficial effect of the utility model is: the utility model carries out the cooperation that clamping can eliminate step axle and stepped hole to the stepped hole cover parts and exists the cover parts of gap and thin-walled stepped hole to clamp the problem that is easy to generate distortion; Convenient mounting and clamping; Improve working (machining) efficiency, reduce cost.

Fig. 1 is the novel generalized section of this reality.
Part explanation: 1, axle body, 2, butterfly spring sheet I, 3, two-way gland, 4, the pressing plate I, 5, the pressing plate II, 6, support set, 7, tight sleeve, 8, clamping screw, 9, feather key, 10, workpiece, 11, butterfly spring sheet II.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described: a kind of from stepped hole self-centering swelling frock; Comprise the axle body 1, the two-way gland 3 that are fixedly mounted on the machine tool chief axis, be satisfied with clamping screw 8 and the tight sleeve 7 of axle body 1 one ends in the axle body 1; Be equipped with butterfly spring sheet I 2 between one end of two-way gland 3 and the axle body 1; Be equipped with butterfly spring sheet II 11 between the other end of two-way gland 3 and the tight sleeve 7, butterfly spring sheet I 2 and butterfly spring sheet II 11 inner bore of step of external diameter and workpiece 10 under nature is a matched in clearance, fixedly is equipped with feather key 9 on the tight sleeve 7; Feather key 9 is positioned at the keyway of axle body 1; Be equipped with support set 6 between butterfly spring sheet II 11 and the tight sleeve 7, be provided with pressing plate I 4 between butterfly spring sheet I 2 and the axle body 1, be provided with pressing plate II 5 between butterfly spring sheet II 11 and the support set 6.
Pretension clamping screw 8 promotion tight sleeves 7, support set 6, pressing plate II 5, butterfly spring sheet II 11, two-way gland 3, butterfly spring sheet I 2 are moved to the left together; This moment, butterfly spring sheet external diameter constantly became big; When distortion is enough big; The endoporus of disc spring film external diameter and workpiece 10 transfers interference fit to by matched in clearance workpiece 10 swellings and self-centering need not centering, workpiece is processed, until reaching technological requirement; Unclamp and take off workpiece after clamping screw 8 makes disc spring film restore nature state, carry out next part again.
