Description
Technical field
The utility model relates to machine tool field, refers in particular to swollen dabber clamp in a kind of self-centering.
Background technology
Tradition internal-expansion type mandrel is by screwing cone bar, force elastic conical drogue generation elastic deformation to realize Clamp blocks, this structure is widely used in lathe, the universal machine tools processing ring cover parts such as milling machine use, but this structure in use mainly contains the shortcoming of two aspects: first, tapered sleeve limits by material own, elastic deformation repeatedly in Reusability process, easy generation fatigue fracture, service life is shorter, second, this clamping mode operation principle realizes clamping by tapered sleeve elastic deformation, tapered sleeve and feature contacts surface discontinuity on microcosmic, thin-walled parts is easily caused to be out of shape, and this fixture self-centering low precision, so be mainly used in the less demanding occasion of element precision, be difficult to be applicable to high precision part processing use.Therefore, the present inventor makes further research this, and develop swollen dabber clamp in a kind of self-centering, this case produces thus.
Utility model content
The purpose of this utility model is to provide swollen dabber clamp in a kind of self-centering, and positioning precision is high, and processing and manufacturing is simple, easy installation and removal.
To achieve these goals, the technical solution of the utility model is as follows:
Swollen dabber clamp in a kind of self-centering, comprises cone bar, tapered sleeve, positioning base, swelling pad, and described tapered sleeve is arranged between swelling pad and cone bar, and described swelling pad is entrenched in positioning base, and described cone bar and tapered sleeve are all positioned at positioning base; Described cone bar comprises the tapered portion being positioned at positioning base, and the tapered sleeve between described tapered portion and swelling pad offers through hole, is provided with ball in described through hole.
Further, described cone bar also comprises the threaded portion be positioned at outside positioning base.
Further, elastic component is provided with between described swelling pad and positioning base.
Further, described elastic component is rubber coil.
Further, described rubber coil is arranged on the dual-side of swelling pad.
After adopting such scheme, the utility model compared with prior art, has the following advantages:
Mechanism structure designed by the present invention is compact, and take up room little, positioning precision is high, and processing and manufacturing is simple, and easy installation and removal, can be widely used in Digit Control Machine Tool, lathe, the use such as milling machine and multi-station clamp.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is the sectional view of Fig. 1;
Label declaration
Cone bar 1, tapered portion 11, threaded portion 12, tapered sleeve 2, positioning base 3,
Swelling pad 4, steel ball 5, rubber coil 6.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
As shown in the figure, swollen dabber clamp in a kind of self-centering that the utility model discloses, comprise cone bar 1, tapered sleeve 2, positioning base 3, swelling pad 4, described cone bar 1 and tapered sleeve 2 are all positioned at positioning base 3, tapered sleeve 2 is arranged between swelling pad 4 and cone bar 1, described swelling pad 4 is around being entrenched in positioning base 3, and swelling pad energy relative positioning base 3 moves; Be provided with rubber coil 6 between swelling pad 4 and positioning base 3, rubber coil 6 is arranged on the dual-side of swelling pad 4.Cone bar 1 comprise be positioned at positioning base 3 tapered portion 11, be positioned at threaded portion 12 outside positioning base 3, threaded portion 12 is for transmission, tapered sleeve 2 between tapered portion 11 and swelling pad 4 offers through hole, is provided with ball in described through hole, the steel ball 5 that this ball is preferably quenched.
This fixture carries out axial displacement by boring bar 1 by screw thread, tapered portion 11 on cone bar 1 promotes to radially move in the through hole of hardened steel ball 5 on tapered sleeve 2, steel ball 5 jack-up swelling pad 4 thus Clamp blocks, swelling pad 4 has positioning base 3 to do guide and limit when radial displacement, can uniform displacement be realized, make the part that is clamped in each position uniform force of clamping area.When unloading part, the oppositely movement of cone bar 1, ring-shaped rubber packing ring shrinks, and swelling pad 4 shrinks, and part is unloaded smoothly.
Above are only specific embodiment of the utility model, but design concept of the present utility model is not limited thereto, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
