The specific embodiment
As shown in Figure 1, the invention provides a kind of high-accuracy grinding external tooth frock, comprises axle 1, positioning disk 3, gland 2, large tapered sleeve 7, conelet cover 6 and locking nut 5,
The step-like through hole in positioning disk 3 with two-stage step, the through hole concentric of two-stage step, and the through hole that internal diameter is large is positioned at the through hole left side that internal diameter is little, the through hole that the through hole that internal diameter is large and internal diameter are little is bellmouth 31,32, and two bellmouths 31,32 cross-sectional diameter of being left side is greater than the cross-sectional diameter on right side;
The outer surface of large tapered sleeve 7 has the conical surface that the inner surface of the bellmouth large with internal diameter 31 matches, and inner surface is cylindrical curved surface, and the outer surface of cylindrical curved surface and workpiece 4 matches, and tapered sleeve 7 has breach 71 greatly;
The outer surface of conelet cover 6 has the conical surface that the inner surface of the bellmouth little with internal diameter 32 matches, and inner surface is cylindrical curved surface, and the outer surface of the cylinder of cylindrical curved surface and axle 1 matches, and conelet overlaps 6 and has breach 61;
In the large through hole of the internal diameter of positioning disk 3 and in the little through hole of internal diameter, there is respectively second largest tapered sleeve 7b and the second conelet cover 6b; In the large through hole of the internal diameter of gland 2 and in the little through hole of internal diameter, there is respectively first tapered sleeve 7a and little tapered sleeve the one 6a;
Cylinder concentric in step-like through hole in positioning disk 3, the step-like through hole in gland 2, large tapered sleeve 7 and conelet cover 6 and axle 1, on positioning disk 3, gland 2, large tapered sleeve 7 and conelet cover 6 cylinders that are placed in axle 1, and the right flank of positioning disk 3 and positioning convex 11 offset, positioning disk 3 is relative with gland 2 positions;
Locking nut 5 is threaded onto on the external screw thread 12 in axle 1, and when locking nut 5 screws, it can coordinate with positioning convex 11 makes positioning disk 3 and gland 2 that workpiece 4 is fixedly clamped.
One end of breach 61,71 on large and small tapered sleeve 6,7 is the blind end 62,72 with enclosed construction, this blind end 62,72 can be positioned near the larger side (as Fig. 3) of tapered sleeve 6,7 cross-sectional diameters, also can be positioned near the less side (as Fig. 2) of tapered sleeve 6,7 cross-sectional diameters.Large and small tapered sleeve 6,7 is made by elastomeric material.The effect of breach 61,71 is tapered sleeve 6,7 inner surface when compacted can be shunk workpiece 4 is clamped, and the effect of blind end 62,72 is to keep the general shape of taper constant when deformation occurs tapered sleeve 6,7, thereby effectively brings into play the effect of pyramidal structure.
Build-up member is head part hole.
The course of work of this example: the first step, positioning disk 3 is enclosed within on the cylinder in axle 1, make the right flank of positioning disk 3 prop up positioning convex 11, interior large and small tapered sleeve 7b, the 6b of putting into respectively in large and small taper hole 31,32 in positioning disk 3, now the inner surface of conelet cover 6b and the cartridge outer surface in axle 1 offset, the contacted inner surfaces of the conical surface 32 that internal diameter in outer surface and positioning disk 3 is little; Second step, workpiece 4 is placed in axle 1 to the now outer surface at straight mouthful of place of workpiece and the contacted inner surfaces of large tapered sleeve 7b, the contacted inner surfaces of the bellmouth 31 that the male cone (strobilus masculinus) of large tapered sleeve 7b and the internal diameter in positioning disk 3 are large; The 3rd step, gland 2 is placed on the cylinder of axle 1 as the mode of positioning disk 3; The 4th step, locking nut is screwed, make workpiece 4 clamped.Finally the frock assembling is assembled to the processing of on gear grinding machines, workpiece 4 being ground external tooth by head part hole.
Above the invention embodiment is had been described in detail, but described content is only the preferred embodiment of the invention, can not be considered to for limiting the practical range of the invention.All equalization variations of doing according to the invention application range and improvement etc., within all should still belonging to the patent covering scope of the invention.
