The invention discloses a numerically controlled combination grinder for the outer diameter and the spherical base surface of a roller. The grinder body of the grinder is L-shaped. A work feeding drag plate and a dresser for the spherical base surface of the roller are mounted behind the left side of the upper part of the grinder body, a grinding abrasive wheel for the spherical base surface of the roller is mounted on the left front side of the grinder body, a grinding abrasive wheel for the outer diameter of the roller is mounted on the right rear side of the upper part of the grinder body, and an abrasive wheel dresser for the outer diameter of the roller is mounted on the right front side of the upper part of the grinder body. The numerically controlled combination grinder for the outer diameter and the spherical base surface of the roller separately processes the outer diameter and the spherical base surface of the roller on one machine tool through one clamping, so that the relative position and other items of precision of the outer diameter of the roller and the spherical base surface of the roller can be well unified and ensured. The spherical base surface of the roller is ground in a manner of directly dressing the outer diameters of the parallel abrasive wheels to required arc sizes and is molded through grinding in a manner of abutting the spherical base surface with the base surface of the roller. The radius R of the spherical base surface of the roller is directly ensured by the outer shape of the abrasive wheel, and the outer shape of the abrasive wheel is ensured by being supplemented and dressed through numerically controlling the linkage of two shafts.
Description
technical field [0001] The invention relates to a numerically controlled roller outer diameter and spherical base surface compound grinding machine, which is mainly aimed at processing the outer diameter and spherical base surface of spherical rollers, cones and cylindrical rollers. Background technique [0002] In the conventional grinding process, the base surface of the roller ball is ground by the Fan Cheng method. The method is to use a bowl-shaped grinding wheel to grind the spherical surface. The base surface of the roller will get a spherical base surface, that is, an arc on the grinding wheel rotates around the center line of the roller, and its trajectory is the spherical end surface of the roller. When working, rotate the grinding wheel seat so that the axis of the grinding wheel rotates an angle a with the center of rotation of the grinding wheel seat, then move the grinding wheel seat laterally, and adjust it to the center of the roller base surface according t...
