The specific embodiment

By reference to the accompanying drawings, the utility model is described in further detail.

As shown in the figure, this practical a kind of enlarging emery wheel, comprises wheel body 1, it is characterized in that: described wheel body 1 comprises with the substrate 10 of an axis hole 100 and a tapered wall 11 that flare circumference 12 is provided; Described flare circumference 12 is towards the front end of wheel, and this front end is formed with an annular groove 13 that inserts ring 3 for accepting the corresponding grinding of enlarging shape; The diameter of the rearward end 130 of described annular groove 13 is less than the inner surface 1 that inserts ring 3, and also has inner surface 2 31 and surface 131 on insertion ring 3; The outside portion 32 of described insertion ring 3 protrudes from the periphery of wheel body 1.Described rearward end 130 and inner surface 1 can be outward-dipping or be sloped inwardly, and also can between space 33 be set and fill jointing material 4.Can be through adjusting between described annular groove 13 and insertion ring 3, allow rearward end 130 and the surface of flare circumference 12 meet at right angles, and the co-operating face 301 that inserts ring 3 meets at right angles with the outer peripheral edges of inserting ring 3, and jointing material 4 is also filled in the gap 330 of between.

As shown in the figure, overall structure of the present utility model as mentioned before.Wherein wheel body 1 is that axis hole 100 is installed for main shaft to the cup-like shape extending out.In the utility model, the diameter of annular groove 13 rearward end 130 is less than the inner surface 30 that inserts ring 3.Therefore, as shown in Fig. 1-2, the face of annular groove 13 rearward end 130 is basic parallel with wheel shaft, and 30 of inner surfaces that insert ring 3 are complementary with groove surface.Such spread pattern, after the rear end of ring 3 covering wheel bodys 1 is inserted in coaxial introducing, insert ring 3 and can slip into and be installed to completely on annular groove 13, because insert the inner surface 1 of ring 3, can slip into smoothly and contact the axle that is parallel to annular groove 13 rearward end 130.The rearward end 130 of insertion ring 3, surface 131 and inner surface 1, inner surface 2 31 are after suitable pretreatment, and inner surface can be fixed or adhere on annular groove 13 with adhesive.Therefore, be appreciated that insertion ring 3 and an assembling wheel that suitable wheel body 1 can complete smoothly that uses a moulding in advance.Therefore,, in previous technology, the step that wheel body 1 is cast to insertion ring 3 just can be saved.Like this, the cost of wheel body 1 reduces, and as installed and inserted ring 3 by injection moulding in suitable durable hard plastic material, is then fixed.

As shown in the figure, enlarging emery wheel also can be arranged like this, and the outside portion 32 of insert 3 protrudes from the periphery of wheel body 1.Due to the rearward end 130 of annular groove 13 with insert complementary inner surface one 30 axially parallels of ring 3, they may have, and some are outward-dipping, as shown in Figure 3.Or the rearward end 130 of annular groove 13 slopes inwardly, as shown in Figure 4 shown in rearward end 130.In this scheme, in the rearward end 130 of insertion ring 13 and the space 33 between inner surface 1, fill after jointing material 4, before assembling, be installed to immediately in annular groove 13, unnecessary like this adhesive will be extruded when assembling, then removes.Fig. 5 further revises example, and rear end face 130 surface basic and periphery 12 of groove meets at right angles or more tilts.The co-operating face 301 that inserts ring also meets at right angles with the outer peripheral edges of inserting ring 3.But this assembling arrangement mode is such, You Yige gap 330 between rearward end 130 and co-operating face 301, can viscose glue or other jointing material 4 or parts in gap, as divide support ring as the connector between rearward end 130 and co-operating face 301, so just effectively stoped trend from the rear axle to wheel body 1 that insert ring 3 motions of.Between the insertion ring 3 of annular groove 13 and rear end face 130, there are the material of filling 4 or support ring, like this when annular groove is worn, can protect that to insert ring 3 not damaged.Such jointing material 4 or support ring can be painted, or by color range, represent to insert grade and the kind of ring 3 abrasive materials.Jointing material 4 or support ring also can be alternative add lines or similar mark, be convenient to stroboscopy and control the optimum speed of wheel turns, be conducive to safety.In addition, a kind of thermal conducting layer also can be placed in and insert between ring 3 and the wheel body 1 of annular groove.But, be limited to actual structure and manufacture method, described enlarging emery wheel can have different periphery inclinations angle.
