Abstract
An annular part grinding fixture comprises a taper handle shaft of hollow structure, an outer taper shaft, an inner taper shaft and a pushing disc. An outer taper face is arranged at one end of the outer taper sleeve, and an inner taper face is arranged at one end of the inner taper sleeve; the outer surface of the outer taper sleeve is sleeved with the inner taper sleeve, and the outer taper face of the outer taper sleeve is matched with the inner taper face of the inner taper sleeve; the outer taper sleeve is fixedly connected with the taper handle shaft, and the inner taper sleeve is fixedly connected with the pushing disc; and the pushing disc is arranged in the outer taper sleeve, and a plurality of axial opening gaps are formed in the outer taper sleeve in the circumferential direction. The annular part grinding fixture is simple in structure, convenient to use, capable of achieving automatic centering, and high in centering precision; and clamping force is controlled, so that clamping deformation can be reduced, and the machining precision is ensured.
Description
Technical field
The present invention relates to a kind of clamp, particularly a kind of auxiliary clamping clamp for annular thin wall class part.
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-shaped work pieces clamp, comprise the taper-shank arbor of hollow structure, external conical sleeve, inner conical drogue and push-plate, 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, described external conical sleeve is fixedly connected with between taper-shank arbor, described inner conical drogue is fixedly connected with between push-plate, described push-plate is arranged in external conical sleeve, described external conical sleeve is along the circumferential direction provided with the open seam of many axis.
In the present invention, described inner conical drogue is connected by straight pin with between push-plate.
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, push rod; 3, external conical sleeve; 4, inner conical drogue; 5, open seam; 6, workpiece; 7, push-plate; 8, straight pin.
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-shaped work pieces clamp, comprise the taper-shank arbor 1 of hollow structure, external conical sleeve 3, inner conical drogue 4 and push-plate 7, 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, be fixedly connected with between external conical sleeve 3 with taper-shank arbor 1, be fixedly connected with between inner conical drogue 4 with push-plate 7, push-plate 7 is arranged in external conical sleeve 3, external conical sleeve 3 is along the circumferential direction provided with the open seam 5 of many axis; Open seam 5 distributes symmetrically and evenly along the circumferencial direction of external conical sleeve 3, can increase the elasticity of external conical sleeve 3.
In the present invention, be connected by straight pin 8 between inner conical drogue 4 with push-plate 7.
During clamping, workpiece 6 is contained in the openend of external conical sleeve 3, then promotes push-plate 7 with push rod 2, push-plate 7 drives inner conical drogue 4 to move right, now under the effect of the inner conical surface of inner conical drogue 4 and the male cone (strobilus masculinus) of external conical sleeve 3, the openend of external conical sleeve 3 starts to reduce, thus is clamped by workpiece 6.
