Abstract
The invention discloses an inner hole processing fixed fixture of ring-like parts. The fixture comprises a taper handle shaft, an outer taper sleeve and an inner taper sleeve, wherein an outer conical surface is arranged at one end of the outer taper sleeve; an inner conical surface is arranged at one end of the inner taper sleeve; the inner taper sleeve coats the outer surface of the outer taper sleeve; the outer conical surface of the outer taper sleeve fits the inner conical surface of the inner taper sleeve; fit threads are arranged on left end planes of the outer taper sleeve and the inner taper sleeve; the outer taper sleeve and the inner taper sleeve are connected through the threads; the outer taper sleeve and the taper handle shaft are fixedly connected; and multiple axial opening gaps are formed in the outer taper sleeve in a peripheral direction. The fixture is simple in structure and convenient to use, can realize automatic centering to achieve high centering precision, and can reduce the clamping deformation to guarantee the processing precision through controlling the clamping force.
Description
Technical field
The present invention relates to machining auxiliary clamping technical field, particularly a kind of for the stationary fixture of ring parts when processing endoporus.
Background technology
Thin-walled ring parts, due to poor rigidity own, is adding man-hour, is very easily out of shape according to scroll chuck clamping, and machining accuracy is difficult to ensure.
Summary of the invention
The invention solves above technical problem, provide a kind of structure simple, positioning precision is high, can effectively reduce the ring-shaped work pieces clamp of pinching deformation.
For solving the problems of the technologies described above, present invention employs a kind of ring parts endoporus processing retaining clip tool, comprise taper-shank arbor, external conical sleeve and inner conical drogue, described external conical sleeve one end is provided with male cone (strobilus masculinus), described inner conical drogue one end is provided with inner conical surface, described inner conical drogue is enclosed within the outer surface of external conical sleeve, the male cone (strobilus masculinus) of described external conical sleeve matches with the inner conical surface of inner conical drogue, the left end plane of described external conical sleeve and inner conical drogue is provided with the screw thread matched, be threaded connection between described external conical sleeve and inner conical drogue, described external conical sleeve is fixedly connected with between taper-shank arbor, described external conical sleeve is along the circumferential direction provided with the open seam of many axis.
Further, in the present invention, be bolted between described external conical sleeve and taper-shank arbor.
Structure of the present invention is simple, easy to use, and can realize self-centering, centering precision is high; By controlling clamping force, can pinching deformation be reduced, ensureing machining accuracy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1, taper-shank arbor; 2, workpiece; 3, external conical sleeve; 4, inner conical drogue; 5, open seam.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
With reference to Fig. 1, for a kind of ring parts endoporus processing retaining clip tool, comprise taper-shank arbor 1, external conical sleeve 3 and inner conical drogue 4, wherein external conical sleeve 3 one end is provided with male cone (strobilus masculinus), inner conical drogue 4 one end is provided with inner conical surface, inner conical drogue 4 is enclosed within the outer surface of external conical sleeve 3, the male cone (strobilus masculinus) of external conical sleeve 3 matches with the inner conical surface of inner conical drogue 4, the left end plane of external conical sleeve 3 and inner conical drogue 4 is provided with the screw thread matched, be threaded connection between external conical sleeve 3 and inner conical drogue 4, be bolted to connection between external conical sleeve 3 and taper-shank arbor 1, external conical sleeve 3 is along the circumferential direction provided with the open seam 5 of many axis, open seam 5 distributes along the even circumferential of external conical sleeve 3, to increase the elasticity of external conical sleeve 3.
When clamping, workpiece 2 is enclosed within the openend of external conical sleeve 3 right-hand member, turns inner conical drogue 4, inner conical drogue 4 is moved right, under the effect of inner conical drogue 4, the opening of external conical sleeve 3 right-hand member inwardly shrinks, thus is clamped by workpiece 2.
