Description
One, technical field: the utility model relates to the bearing grinder technical field, especially with the ball basal plane grinding machine chuck mode clamping device of spiral lamination.
Two, background technology:, increasingly high to the precision and the life requirements of bearing along with the development of China's bearing industry.And taper roller is the important component part of taper roll bearing, and the height of its machining accuracy directly influences the precision and the life-span of bearing.Taper roller ball basal plane is again the part that in conical bearing, contacts with the bearing inner race rib; And the relative motion of this part is not to roll but slip; Because sliding friction is big than coefficient of rolling friction; Be easy to cause the premature failure of bearing, the machining accuracy that therefore improves taper roller ball basal plane is most important for the precision and the life-span of improving taper roll bearing.
To be roller and emery wheel carry out grinding around center line rotation separately to the processing method of current roller ball basal plane, to obtain required spherical radius.And the chuck mode clamping mode is adopted in the clamping of roller, and the rotary principle of its principle simulation taper roller in bearing designs.But in actual production process since roller radially, axial runout is bigger, the product precision is lower.
Three, summary of the invention: the purpose of the utility model provides the ball basal plane grinding machine chuck mode clamping device of the band spiral lamination that a kind of efficient is high, crudy is high; It solved other technological roller radially, axial runout is bigger; The problem that the product precision is lower, the purpose of the utility model be achieved in that it be rigidity inner disc, separator, end face location, taper roller, elasticity coil outward, diamond pen trimmer, emery wheel, emery wheel terminal pad be formed by connecting; The rigidity inner disc is connected with the inner main axis screw; Separator is connected with middle spindle screw, and the end face location is connected with the separator screw, and the small end face of taper roller contacts with the end face location, the taper seat of taper roller is coiled clamping outward by rigidity inner disc and elasticity respectively; The large end face of taper roller contacts with the grinding face of emery wheel; The outer dish of elasticity is connected with outer spindle screw, and the diamond pen trimmer is connected with the outer shaft screw, and emery wheel is fixed on the grinding wheel spindle through the emery wheel terminal pad.One end of rigidity inner disc is a connection handle, and the other end of rigidity inner disc has conicle dish and big circular cone dish, near the conelet disk of connection handle less than the big circular cone dish of another one.
In the middle of the rigidity inner disc, there are bolt hole, the circular cone disc portion of rigidity inner disc that 6 fabrication holes that are uniformly distributed with are arranged.
Be useful on the spiral lamination that makes roller in rotation process, receive axial thrust load on the taper seat of the conicle dish of rigidity inner disc and big circular cone dish.
During work because rigidity inner disc circular cone contact surface has spiral lamination, when line of vision perpendicular to the big end of rigidity inner disc when turning clockwise, the spiral lamination employing is left-handed; When line of vision perpendicular to the big end of rigidity inner disc when being rotated counterclockwise, spiral lamination adopts dextrorotation; Outside through rigidity inner disc and elasticity, produced along the component of taper roller axial direction in the rotary processing process of dish like this; Thereby guarantee that taper roller small end end face remains consistent with end face location locating surface; So not only reduce axial, the circular runout of taper roller in process, improved the product precision; And the stability of lathe also is improved, and reduced the accident rate of lathe.Enhance productivity simultaneously, reduce the Production of bearing cost.
