Description
Technical field
The utility model relates to a kind of jig, particularly relates to a kind of grinding fastener for two half bear inner ring grooved railway of bearing.
Background technology
On special bearing mill processing raceway groove lathe for the grinding of 3 points, two half bear inner ring grooved railway of 4 angular contact ball bearings in prior art, magnechuck is utilized to adsorb ring face, adopt two point supporting location inner ring external diameter, abrasive grinding wheel is trimmed to peach type, utilizes plunge method to carry out grinding and complete half peach type raceway groove grinding; And another peach type raceway groove is also adopt same mill processing method to carry out grinding-shaping.But by twice location that is installed, because the repetitive positioning accuracy of trimming wheel and the wearing and tearing of emery wheel are difficult to make two and half peach type raceway grooves be on the peach type raceway groove circular arc of a standard.Namely ditch shape difference is poor, and the difference in size of the two and half peach type raceway grooves successively ground, groove out of square equidimension and form and position tolerance precision are difficult to meet technological requirement, adopt this mode that is installed, 3 points, 4 angular contact ball bearings bear footpath after mounting, and the ability of axial load and disturbing moment is all poor, thus must study a kind of new fixture structure, manage to improve its grinding quality, to meet its end product quality requirement better.
Utility model content
For the present situation of above-mentioned prior art, it is simple that technical problem to be solved in the utility model is to provide a kind of structure, for the jig of the two half grinding raceway of inner ring processing of bearing.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of grinding fastener for two half bear inner ring grooved railway of bearing, comprise fixture body, described fixture body central authorities are provided with boss and undercut, the axle core place of the side of this boss and undercut has center hole, described boss and undercut one end are connected with mandrel, the other end of this boss and undercut is provided with clamping packing ring, and this clamping bead outward has nut.
Further, the both ends of the surface of described fixture body are provided with center hole, and center hole is used for the Set and Positioning of workpiece.
Compared with prior art, the utility model has the advantage of: the utility model compact conformation, workpiece is positioned on fixture body, accurately located by the center hole at boss and undercut axle core place, then will washer locking be clamped by nut, make workpiece be fixed on raised head face and mandrel, thus reach the object of two half bear inner ring grooved railway of grinding bearing simultaneously, this grinding fastener structure is simple, improves the grinding quality of two half bear inner ring grooved railway of bearing, is applicable to large-scale promotion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of grinding fastener for two half bear inner ring grooved railway of bearing, comprise fixture body, the central authorities of described fixture body are provided with boss 11 and the undercut 12 of place work piece 2, the axle core place, side of this boss 11 and undercut 12 is provided with center hole 15, the left end of described boss 11 and undercut 12 is mandrels 1 of fixture body, there is screw thread mandrel 1 front end of this fixture body, the right-hand member of undercut 12 is provided with clamping packing ring 13, the right side of clamping packing ring 13 is connected with nut 14, workpiece is pressed against by clamping packing ring 13, clamping packing ring 13 is compressed again with nut 14, workpiece is firmly fixed on boss 11 end face and mandrel 1.。
Preferably, in order to the clamping of workpiece 2 is located better, the both ends of the surface of described fixture body 1 are provided with center hole 12.
During use, the inner ring of two band half peach type raceway grooves is placed on relatively and middle relies on sliding fit to be put into mandrel 1 to get on, the end face of one of them inner ring leans against on boss 11 end face of fixture body mandrel 1, another inner ring end face clamping packing ring 13 and nut 14 are locked, then center hole 15 location, fixture body mandrel 1 two ends is relied on to process, twice trimming wheel is passed through subsequently with diamond pen, wheel face is trimmed to peach type, axial displacement is controlled with dial gauge, an emery wheel radial direction incision grinding work piece, just can complete the grinding of two and half peach type raceway grooves, this grinding fastener is adopted to carry out grinding, because two and half peach type raceway grooves grind at the lower emery wheel that same a slice trims that is once installed, therefore can ensure that the ditch shape of two and half peach type raceway grooves is poor, the required precision of difference in size and other form and position tolerance, and then every quality requirement of its finished product can be met.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, it will be understood by those of skill in the art that it still can be modified to the technical scheme described in previous embodiment, or wherein portion of techniques feature has been replaced on an equal basis; And these amendments or replacement, do not make the essence of appropriate technical solution depart from spirit and the scope of each embodiment technical scheme of the utility model.
