Abstract
An inner hole machining fixing clamp for ring parts comprises a taper-shank shaft, an outer taper sleeve and an inner taper sleeve. An outer taper surface is arranged at one end of the outer taper sleeve, an inner taper surface is arranged at one end of the inner taper sleeve, the inner taper sleeve is arranged on the outer surface of the outer taper sleeve in a sleeved mode, the outer conical surface of the outer taper sleeve is matched with the inner conical surface of the inner taper sleeve, matched threads are arranged on the left end plane of the outer taper sleeve and the left end plane of the inner taper sleeve, the outer taper sleeve and the inner taper sleeve are connected through threads, the outer taper sleeve is fixedly connected with the taper-shank shaft, and multiple axial opening seams are formed in the circumferential direction of the outer taper sleeve. The inner hole machining fixing clamp for the ring parts is simple in structure and convenient to use, automatic centering can be achieved, and locating precision is high. Clamping deformation can be reduced by controlling clamp force, and machining precision can be guaranteed.
Description
Technical field
The utility model relates to machining auxiliary clamping technical field, particularly a kind of stationary fixture of using in the time processing endoporus for ring parts.
Background technology
Thin-walled ring parts, due to poor rigidity own, is adding man-hour, if adopt very easily distortion of scroll chuck clamping, machining accuracy is difficult to ensure.
Utility model content
The utility model has solved above technical problem, provides a kind of simple in structure, and positioning precision is high, can effectively reduce the ring-shaped work pieces clamp that clamps distortion.
For solving the problems of the technologies described above, the utility model has adopted 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, in the left end plane of described external conical sleeve and inner conical drogue, be provided with the screw thread matching, between described external conical sleeve and inner conical drogue, be threaded connection, between described external conical sleeve and taper-shank arbor, be fixedly connected with, on described external conical sleeve, be along the circumferential direction provided with many axial open seam.
Further, in the utility model, between described external conical sleeve and taper-shank arbor, be bolted.
The utility model is simple in structure, easy to use, can realize self-centering, and centering precision is high; By controlling clamping force, can reduce and clamp distortion, ensure machining accuracy.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
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 utility model is further described.
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 are provided with male cone (strobilus masculinus), inner conical drogue 4 one end are 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, in the left end plane of external conical sleeve 3 and inner conical drogue 4, be provided with the screw thread matching, between external conical sleeve 3 and inner conical drogue 4, be threaded connection, between external conical sleeve 3 and taper-shank arbor 1, be bolted to connection, on external conical sleeve 3, be along the circumferential direction provided with many axial open seam 5, open seam 5 distributes along the even circumferential of external conical sleeve 3, to increase the elasticity of external conical sleeve 3.
In the time of clamping, workpiece 2 is enclosed within to the openend of external conical sleeve 3 right-hand members, turn 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 members inwardly shrinks, thereby workpiece 2 is clamped.
