Abstract

The invention provides a guide wheel dresser feeding structure of an air valve rod-part numerical control centerless grinding machine, which can guarantee the straight feed accuracy of a guide wheel dresser, guarantee the feed precision of the guide wheel dresser, reduce the movement load of a ball screw and can ensure the long working service life of the ball screw. The guide wheel dresser feeding structure comprises a guide wheel dresser, a base, a servo motor, a ball screw and a screw nut, wherein the guide wheel dresser is supported on the base, the servo motor drives the ball screw, the ball screw is connected with the screw nut in a threading way, one end of the screw nut is tightly connected with the guide wheel dresser, and the guide wheel dresser feeding structure is characterized in that the upper end surface of the base is provided with a dovetail straight lead-rail groove, the bottom of the guide wheel dresser is provided with a dovetail lead rail, the dovetail lead rail is embedded inside the dovetail straight lead rail groove, the servo motor is connected with the input end of a reducer, and the output end of the reducer is connected with the input end of the ball screw.

Description

technical field [0001] The invention relates to the structural field of a centerless grinder, in particular to a guide wheel dresser feed structure of a valve stem numerically controlled centerless grinder. Background technique [0002] The guide wheel dresser of the existing valve stem CNC centerless grinder is driven by the ball screw driven by the servo motor. The lead screw drives the lead screw nut. Due to the weight of the guide rail dresser, the motion load of the rolling screw rod is large, which makes the ball screw easy to shake slightly when driving, resulting in low feed accuracy of the guide wheel dresser. SUMMARY OF THE INVENTION [0003] In view of the above problems, the present invention provides a guide wheel dresser feed structure for a valve stem CNC centerless grinder, which makes the linear feed of the guide wheel dresser accurate, ensures the feed accuracy of the guide wheel dresser, and reduces the number of balls. The motion load of the screw ...
