As the further improvement of such scheme, coaxially on one end that cylinder extends cylindrical cavity be provided with backstay.
As the further improvement of such scheme, baffle plate one is formed by the extension of overcoat corresponding end-faces radial direction.
As the further improvement of such scheme, baffle plate two is extended to form by overcoat corresponding end-faces radial direction.
As the further improvement of such scheme, described overcoat is divided into several equal-sized lobes.
As the further improvement of such scheme, described overcoat is divided into three lobes.
As the further improvement of such scheme, described elastic component one is stage clip.
As the further improvement of such scheme, described elastic component two is steel wire ring or the steel ring of opening.
Beneficial effect
Compared with prior art, the present invention has the following advantages:
1. the present invention adopts flexible reducing mandrel technology, be applicable to internal diameter inaccurate, need certain anti-machining deformation ability and add the workpiece having man-hour variations in temperature and needs frequently to change;
2. the present invention and workpiece to be machined are that face contacts but not point cantact, and stress surface is large, so the workpiece of not fragile thin-walled;
3., due to the protection of overcoat, annealing when stage clip can not be heated to because of processing and make spring malfunctioning, can not wear and tear because of the telescopic moving of spring workpiece, and the rust stain of workpiece inner wall also can not enter stage clip gap, and to cause stage clip to stretch limited.

Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is described in more detail.Should be appreciated that specific embodiment described herein only to explain the present invention, be not intended to limit the present invention.
As shown in Fig. 1 Fig. 2, a kind of reducing elastic central spindle clamping device, comprises mandrel 1, overcoat 2, elastic component 1, elastic component 24.One end of mandrel 1 is the frustum of a cone 11 that diameter diminishes successively, and the other end is the isometrical cylinder 12 of a diameter.The diameter of cylinder 12 is less than the maximum gauge of the frustum of a cone 11, and cylinder 12 is coaxial with the frustum of a cone 11.Overcoat 2 comprises, and to synthesize profile be several lobes 21 columniform.The outer wall two ends of overcoat 2 are provided with groove, are provided with elastic component 24 in groove, and it is columniform overcoat 2 that several lobes 21 are synthesized profile by elastic component 24.The inside, one end of overcoat 2 is provided with the conical cavity 24 for accommodating the frustum of a cone 11 and end face is provided with baffle plate 1.The other end inside of overcoat 2 is provided with the cylindrical cavity 25 for accommodating elastic component 1 and end face is provided with baffle plate 2 23.Cylindrical cavity 25 communicates with conical cavity 24.One end of cylinder 12 to be housed in cylindrical cavity 25 and to be arranged with elastic component 1, and the other end of cylinder 12 extends cylindrical cavity 25.The frustum of a cone 11 is spacing inner at overcoat 2 by baffle plate 1 and baffle plate 2 23 with elastic component 1.
As shown in Figure 3, in specific works, reducing elastic central spindle clamping device is positioned at (the present embodiment provides a kind of flange welder) on machining machine and tool, operating grip 6 moves compression garment 2 to the right, overcoat 2 slides along mandrel 1 conical surface and stretches out the frustum of a cone 11, cylindrical cavity axial shrinkage in overcoat 2, elastic component 1 is also compressed thereupon; Several lobes 21 stretching out the overcoat 2 of the frustum of a cone 11 tighten up by elastic component 24, and the external diameter of overcoat 2 diminishes, and now, workpiece can be enclosed within outside overcoat 2.Unclamp operation handle 6, overcoat 2 slides to the left along mandrel 1 taper seat under the bounce effect of elastic component 1, several lobes 21 under the effect of the conical surface gradually spreading until baffle plate 1 props up end face or the overcoat 2 outer surface top tight workpiece inner surface of the frustum of a cone 11 minor axis end, so far, the clamping work of workpiece completes.After work pieces process completes, operating grip 6 is moved compression garment 2 to the right, overcoat 2 slides along mandrel 1 conical surface, and overcoat 2 tightens up by elastic component 24, can take off workpiece after the external diameter of whole overcoat 2 diminishes.
In the above-described embodiments, in order to more convenient, fixture is positioned on machining machine and tool, coaxially on one end that cylinder 12 extends cylindrical cavity 25 is provided with the backstay 5 being easy to fixing.Baffle plate 1 and baffle plate 2 23 are formed by the extension of overcoat 2 corresponding end-faces radial direction, make jacket structure more stable.When overcoat 2 is divided into 3 equal-sized lobes 21, and elastic component 1 is stage clip and elastic component 24 when being steel wire ring or steel rings of opening, the contraction of overcoat 2 and the dismounting of workpiece and clamping effect better.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
