A method of using a non-magnetic clamping workpiece rotary table for a bearing ball base surface grinding machine

Abstract

The invention discloses a use method of a revolving platform of a non-magnetic clamping workpiece used for a bearing ball base surface grinding machine. A self-positioning device with buffering is used, an inner taper hole of the lower end of an upper main shaft is connected with an outer taper surface of the upper end of a lower main shaft in a matched mode, an upper pressing shaft is connected into inner threads of an upper pressing plate in a screwed mode, the lower taper surface of the upper pressing shaft is connected into a taper hole of the upper end of the upper main shaft, and the condition that the upper main shaft and the lower main shaft are provided with a same central axis is ensured; the condition that the upper main shaft and the lower main shaft are stationary in the grinding process of an upper revolving disc and a lower revolving disc is ensured; self-rotation grinding of a tapered roller is realized from a second motor, a belt, an upper belt wheel, the upper revolving disc, a gear disc to a gear shaft; and orbital revolution grinding of the tapered roller is realized from a first motor, a lower belt, a lower belt wheel to the self-positioning device with buffering around the central axis of the lower main shaft. Phenomena that the tapered roller is prone to having poor stability, generating axial movement and the like are overcome, end surface circular run-out errors of the ball base surface of the tapered roller are reduced, and the grinding efficiency and precision are improved.

Description

technical field [0001] The invention belongs to the technical field of special equipment for bearing grinding, in particular to a method for using a non-magnetic clamping workpiece rotary table used for a bearing ball base surface grinding machine. Background technique [0002] The domestic grinding machine for grinding the spherical surface of tapered rollers adopts spherical surface grinding machines. During the grinding process of tapered rollers, the tapered rollers to be ground are located in the tooth grooves of the isolation disk. Since the rotation speed of the left guide wheel is higher than that of the right guide The wheel disc is lower and the two guide wheel discs rotate in opposite directions with different speeds. The manufacturing accuracy of the working cone surface of the isolation disc and the left and right guide discs is difficult to meet the design requirements, resulting in the extension line of the working surface of the isolation disc not being able t...
