Grinding equipment

Abstract

PROBLEM TO BE SOLVED: To provide a grinding device capable of simplifying work and capable of enhancing accuracy by dispensing with teaching work, by automatically performing a series of grinding work, without stopping the device once a work is arranged even the work is a large bearing ring or the like.SOLUTION: A bearing detecting part 30 comprises a contactor 31, and detects a position and a shape of a bearing inner ring 1 by bring the contactor 31 into contact with the bearing inner ring 1. A grinding wheel operation part 50 comprises a servomotor, and moves a grinding wheel 41 by driving the servomotor of the grinding wheel operation part 50. A coordinate system-related information group such as position-shape information based on an origin Owith the main shaft rotational center as a reference, is stored in a storage part 71 of a control part 70. The control part 70 positions the grinding wheel 41 by controlling the grinding wheel operation part 50 by integrating respective coordinate systems of the bearing inner ring 1, the grinding wheel 41 and a dress 61 on the basis of the coordinate system-related information group in the storage part 71 and driving information on the servomotor of the grinding wheel operation part 50.

Description

technical field [0001] The present invention relates to a grinding processing device, more specifically, to a grinding processing device for grinding a large bearing ring. Background technique [0002] When using a conventional general grinding machine to grind a bearing ring as a workpiece (processing object), for example, it is necessary to contact the grinding wheel to the processing surface such as the outer peripheral surface of the bearing ring in advance, and perform the grinding process. The device teaches the teaching (pre-processing) operation of the processing part. In addition, in order to properly dress the grinding tool, it is also necessary to perform teaching work on the dressing portion. If this teaching operation is not performed properly, not only the machining accuracy may be affected, but also a mechanical collision may be caused. Therefore, the teaching work before the grinding process is a very important preliminary process, and requires a high skill...

Problems solved by technology

Therefore, in recent years, there has been a tendency that the burden of teaching work has become heavier and heavier.

Especially in the case of parts that are ground for the first time, or in the case of batch adjustment of large bearing rings that cannot be used with a processing measuring instrument, in its dimensional adjustment, it is necessary to repeatedly process and measure, so it will cost more. much labor and time
