Description

Clamping device for grinding end face of spherical roller Technical Field The utility model relates to the technical field of bearing roller processing, in particular to a clamping device for grinding the end face of a spherical roller. Background As shown in the polishing device for the double end surfaces of the bearing roller disclosed in the chinese patent publication No. CN114473675a, currently, a face grinder or a lapping machine is used to process the end surfaces of the cylindrical roller, which is a relatively common technology; for a vertical double-end-face grinding machine, the equipment is generally of a vertical structure of an upper grinding wheel and a lower grinding wheel, the working principle is that the upper grinding wheel is reduced according to the pressure set by a program and is contacted with a workpiece in a workpiece carrying disc arranged on the lower grinding wheel, and meanwhile, according to the requirements of a processing technology, the upper grinding wheel, the lower grinding wheel and the workpiece carrying disc are independently moved according to the rotating direction and the rotating speed set by the program to finish grinding; However, the existing workpiece carrying disc is used for placing cylindrical rollers through the through holes for rotation processing, when the spherical rollers or aligning rollers with arc-shaped processing walls are processed, the spherical rollers are quite easy to fall due to the fact that the existing through holes are limited and unstable, the end faces of the spherical rollers are not only failed to process, but also upper and lower grinding wheels can be damaged, and huge losses are caused. Disclosure of utility model In order to overcome the defects in the background art and solve the problems in the prior art, the utility model discloses a clamping device for grinding the end face of a spherical roller, which can stably clamp the spherical roller and is suitable for processing various bearing rollers. In order to achieve the above purpose, the utility model adopts the following technical scheme: The clamping device for grinding the end face of the spherical roller comprises a workpiece carrying disc, wherein a plurality of mounting holes for placing the roller are uniformly and annularly arranged on the disc face of the workpiece carrying disc, so that when the workpiece carrying disc is driven to rotate, the end face of the roller exposed out of the mounting holes can be ground by an external grinding wheel, the mounting holes are stepped holes, each stepped hole comprises an upper hole section, a middle hole section and a lower hole section, the pore walls of the upper hole sections are provided with internal threads and are in fit and screwed connection with screw plugs, and the end faces of the screw plugs are provided with through holes, the pore diameters of which are smaller than those of the middle hole sections. Further, the through hole of the screw plug and the hole diameter of the lower hole section are the same, and the thickness of the screw plug is lower than the depth of the upper hole section. Further, the outer end face of the screw plug is provided with at least two dismounting holes. Further, the upper port of the lower hole section and the lower port of the through hole of the screw plug are respectively provided with a chamfer. Further, a buffer gasket is adhered to the chamfer. Furthermore, the workpiece carrying disc and the screw plug are both made of engineering plastic materials. Further, the workpiece carrying disc is provided with an outer gear ring and is driven to rotate through gear transmission with an external driving mechanism. Due to the adoption of the technical scheme, the utility model has the following beneficial effects: according to the clamping device for grinding the end face of the spherical roller, after the barrel-shaped spherical roller with the fat two ends in the middle is placed into the mounting hole, the step at the upper end of the lower hole section can be used for supporting the arc-shaped side wall of the spherical roller, the lower end of the spherical roller is exposed from the lower end of the lower hole section, the grinding wheel is convenient to process, the screw plug screwed into the upper hole section can also support the arc-shaped side wall of the spherical roller, the spherical roller is clamped and positioned, and the spherical roller is prevented from tilting and damaging the grinding wheel in the process of processing.
