Description

A kind of fixture of lathe processing slim annular thin wall part
Technical field
The utility model relates to a kind of fixture of lathe processing slim annular thin wall part, belongs to turning tool technical field.
Background technology
Thin-walled parts work in-process produces distortion becomes common recognition substantially, and it is just larger that it always is that machine adds the thin-wall part difficulty of processing of the emphasis of industry research, particularly slender axles.
In prior art, to the processing of ring-shaped work pieces, generally adopt 1) Internal hole positioning, then spell with bolt and tightly carry out turning, this method location is poor, and installs trouble; 2) reserved certain allowance, cuts off this allowance after accessory turning completes again, but adopts the method not only to waste material, and easily produces burr time part cuts off, and also produces distortion simultaneously.Above two kinds of modes are all applicable to the little and annular element that internal diameter is larger of axial dimension, for elongated annular thin wall part, add man-hour rigidity bad, easy generation cutter relieving, cause roughness, size etc. do not reach designing requirement, ensure the processing of such part at present without more ripe technological equipment.
Utility model content
The purpose of this utility model is: provide that a kind of structure is simple, easy to use, positioning precision is high, can greatly improve working (machining) efficiency the fixture of lathe processing slim annular thin wall part, to overcome the deficiencies in the prior art.
The fixture of a kind of lathe processing slim annular thin wall part of the present utility model, comprise chuck body, spell jack panel and tighten up tapered sleeve, the stepped cylindrical body structure that described chuck body is made up of roundlet shell of column and great circle shell of column, the cylindrical of great circle shell of column is provided with external screw thread, and great circle shell of column is provided with location endoporus; The endoporus of described spelling jack panel is divided into two sections, and one section is internal thread, and another section is inner conical surface, and the spelling internal thread of jack panel and the external screw thread of chuck body spin; Described tightens up tapered sleeve shape for conical, and tighten up the ends contact of the large end of tapered sleeve and great circle shell of column, the inner conical surface of spelling jack panel is enclosed within and tightens up on the male cone (strobilus masculinus) of tapered sleeve.
The described tapered sleeve that tightens up is provided with two groups of retraction slots, and retraction slot is axially uniformly distributed along male cone (strobilus masculinus).
The described male cone (strobilus masculinus) tightening up tapered sleeve is identical with the inner conical surface tapering of spelling jack panel, thus ensures that the male cone (strobilus masculinus) tightening up tapered sleeve can fit tightly with the inner conical surface of spelling jack panel.
The length of described male cone (strobilus masculinus) is less than or equal to the length of inner conical surface, ensures that male cone (strobilus masculinus) can be fitted on inner conical surface all the time.
Described internal thread and external screw thread are fine thread, are convenient to fine setting, improve positioning precision.
Compared with prior art, the utility model has the advantage of: the utility model is when the elongated annular thin wall part of turnery processing, first by Conventional processing methods, part outer car is gone out, again by tightening up tapered sleeve Internal hole positioning, chuck body regulate the counterbore degree of depth to carry out clamping according to part actual size, finally coordinated with the inner conical surface of spelling jack panel by the male cone (strobilus masculinus) tightening up tapered sleeve, by rotating screw thread, axially tighten up elongate annular thin wall part, now just chuck body clamping can be processed elongated annular thin wall part on lathe, after turnery processing completes, binding nut is unclamped in rotation, take off and tighten up tapered sleeve and just easily can take out workpiece.The utility model not only convenient mounting and clamping, fast, accurate positioning, and also by the protection of clamp body, strengthen the rigidity of elongated annular thin wall part, the situation avoiding cutter relieving or bullet to become occurs, and ensures the machining accuracy of part.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with drawings and Examples, the utility model is described in further detail.
Case study on implementation of the present utility model: the structural representation of the fixture of lathe processing slim annular thin wall part as shown in Figure 1, comprise chuck body 1, spell jack panel 2 and tighten up tapered sleeve 3, see Fig. 2, the stepped cylindrical body structure that described chuck body 1 is made up of roundlet shell of column 7 and great circle shell of column 8, the cylindrical of great circle shell of column 8 is provided with external screw thread 9, and great circle shell of column 8 is provided with location endoporus 10; See Fig. 3, the endoporus of described spelling jack panel 2 is divided into two sections, and one section is internal thread 5, and another section is inner conical surface 6, and the internal thread 5 of spelling jack panel 2 spins with the external screw thread 9 of chuck body 1, and described internal thread 5 and external screw thread 9 are fine thread.See Fig. 4 and Fig. 5, described tightens up tapered sleeve 3 shape for conical, and tighten up tapered sleeve 3 and hold greatly the ends contact with great circle shell of column 8, the inner conical surface 6 of spelling jack panel 2 is enclosed within and tightens up on the male cone (strobilus masculinus) 11 of tapered sleeve 3; The described male cone (strobilus masculinus) 11 tightening up tapered sleeve 3 is identical with inner conical surface 6 tapering of spelling jack panel 2, and the length A of male cone (strobilus masculinus) 11 is more than or equal to the length B of inner conical surface 6.The described tapered sleeve 3 that tightens up is provided with two groups of retraction slots 12, and retraction slot 12 is axially uniformly distributed along male cone (strobilus masculinus) 11.
During installation, see Fig. 1, first the roundlet shell of column 7 on lathe three-claw gripper chuck clamper body 1 is utilized, then elongated annular thin wall part 4 is put into the location endoporus 10 in chuck body 1, then be inserted in and tighten up tapered sleeve 3, the inner conical surface 6 of spelling jack panel 2 is enclosed within and tightens up on the male cone (strobilus masculinus) 11 of tapered sleeve 3, and the internal thread 5 of spelling jack panel 2 spins with the external screw thread 9 of chuck body 1, and axially tighten, now just can hole or boring to elongated annular thin wall part 4.After machining, unscrew and spell jack panel 2, take off and tighten up tapered sleeve 3 and just easily can take out elongated annular thin wall part 4, complete processing.
