In order to solve the above technical problems, the utility model provides an automatic grinding device for a horizontal ring grinding machine, which includes a horizontally arranged grinding wheel mounting bracket. One end of the grinding wheel mounting bracket is a hollow hoop structure, and also includes a grinding wheel. In the hoop and fixedly connected with the grinding wheel mounting bracket through the grinding wheel fastening bolts, the thickness of the grinding wheel is greater than the thickness of the hoop, that is, the upper and lower surfaces of the grinding wheel protrude out of the hoop;

It also includes upper tapered rollers and lower tapered rollers arranged symmetrically along the direction perpendicular to the plane of the grinding wheel. The other end of the grinding wheel mounting bracket is also horizontally provided with a beam. The beam is perpendicular to the grinding wheel mounting bracket and the centerlines of the two coincide. and the lower surface of the two is fixed by bracket fixing bolts;

The two ends of the beam are symmetrically connected with the two supporting plates through the beam connecting bolts;

Technical effect: the utility model puts the grinding wheel on the lower cone roller through the rotation of the cone roller of the horizontal ring rolling machine, and the upper cone roller pressurizes the grinding wheel, and simultaneously grinds the upper and lower cone rollers in the ring direction, and passes through the cone roller frame The translation of the tapered roller is used to grind the straightness of the axial direction of the tapered roller.

The technical scheme that the utility model is further limited is:

Further, in the aforementioned automatic grinding device for a horizontal ring rolling machine, the number of bracket fixing bolts is four, and they are evenly distributed in a square structure at the junction of the grinding wheel mounting bracket and the beam.

In the aforementioned automatic grinding device for a horizontal ring rolling machine, the number of crossbeam connecting bolts is four and two by two are distributed at both ends of the crossbeam.

The beneficial effects of the utility model are:

The automatic grinding device for the horizontal ring grinding machine designed by the utility model adopts the principle of automatic grinding, which effectively reduces the safety hazards encountered in manual grinding, improves the grinding efficiency, and greatly reduces the tooling of the ring grinding machine. The cost is reduced, the maintenance efficiency and the utilization rate of the equipment are improved, and the output is effectively increased.
