Outer circle grinding device for thin and long shaft workpiece

Abstract

An outer circle grinding device for a thin and long shaft workpiece comprises a head frame centre and a tail frame centre. The thin and long shaft workpiece is arranged between the head frame centre and the tail frame centre and arranged in a machine shell. A plurality of grinding mechanisms are arranged in the machine shell. Each grinding mechanism comprises a lead screw, wherein the two ends ofthe lead screw are arranged on a fixing base and a supporting base correspondingly, one end of the lead screw is connected with a hand wheel after stretching out of the fixing base, the lead screw isin screw joint with a nut, the nut is fixedly connected with a grinding wheel frame, the grinding wheel frame is fixedly connected with a sliding block, the sliding block is in sliding connection witha guide rail in the machine shell, the grinding wheel frame is further fixedly connected with a motor, an outer ring of a first bearing and an outer ring of a second bearing, the inner ring of the first bearing is connected with an output shaft of the motor, the output shaft is connected with a drive gear, the drive gear is engaged with a driven gear, and the driven gear is connected with a grinding wheel through a transmission rod. Grinding force of various grinding wheels to the thin and long shaft workpiece offset with one another, and the machining precision is improved; and a rolling guide rail is adopted for positioning, and the workpiece machining quality is guaranteed.

Description

technical field [0001] The invention belongs to the field of grinding devices for slender shaft workpieces, in particular to a cylindrical grinding device for slender shaft workpieces. Background technique [0002] Due to the small diameter and large length of the slender shaft workpiece, it has poor rigidity during grinding and is easily deformed under the action of grinding force. Using the traditional grinding device, the workpiece is easily bent and deformed under the action of radial grinding force, which affects the machining accuracy of the workpiece. Therefore, in order to solve the technical problems currently faced by the slender shaft workpiece and improve the processing quality, the cutting of the grinding wheel must be considered. The effect of force on workpieces with slender shafts. Secondly, the existing slender shaft grinding device fixes the workpiece only by two tops at the head and the tail to clamp the workpiece. Concave-convex on the outer surface of ...
