Static pressure dresser of super-grinding bearing outer ring raceway grinding wheel and dressing method

Abstract

Provided are a static pressure dresser of a super-grinding bearing outer ring raceway grinding wheel and a dressing method. The dresser comprises a base sleeve, a servo motor, a sleeve, an upper end cover, an upper hydrostatic bearing, a lower end cover, a lower hydrostatic bearing, a pen chuck, a corundum pen and a spindle, wherein the sleeve is sleeved by the base sleeve, the spindle is sleeved by the sleeve, the upper end cover and the lower end cover are respectively arranged at the upper end and the lower end of the sleeve, the upper hydrostatic bearing and the lower hydrostatic bearing are supported between the spindle and the sleeve, the pen chuck is installed at the lower end of the spindle, the corundum pen is installed on the pen chuck, and the servo motor is connected with the upper end of the spindle. The dressing method comprises the steps of S1, enabling the grinding wheel to be in contact with the corundum pen of the static pressure dresser; S2, setting the contact position of the corundum pen and the grinding wheel and a rotating angle of the spindle; S3, starting a grinding wheel driving shaft and the servo motor and beginning to perform grinding trimming on the grinding wheel; S4, enabling the grinding wheel driving shaft and the servo motor to shut down after grinding trimming and moving away the corundum pen.

Description

technical field [0001] The invention relates to the superfine grinding ball bearing processing technology, in particular to a static pressure dresser and a dressing method for the grinding wheel of the outer ring groove of the superfine grinding ball bearing. Background technique [0002] Rolling hydraulic bearing is an important part of various mechanical assemblies. Its precision, performance, life and reliability play a decisive role in the precision, performance, life and reliability of the main engine, and directly determine the machining accuracy of the ground parts.
