Inner Ring Raceway Grinder For Bearing Ring Based On PLC Design Of Control System

This topic comes from the transformation of a 3 MZ2110 grinder of a bearing company.The purpose of the pro Ect is to transform the hydraulic 3MZ2110 grinder into a fully automatic CNC grinder.As a very important machining equipment,the grinding machine occupies more than 60% of the load in the bearing processing.Hydraulic type grinder old-fashioned manual grinding feed compensation in operation,and is easy to be such as environmental temperature,humidity and air quality hydraulic oil factors,so the production efficiency is low,low precision and high maintenance cost,material consumption is relatively large.The transmission of the grinding machine adopts hydraulic transmission,so the temperature is too high or too low,or the operation time is longer and lead to the increase of oil temperature,will seriously affect the accuracy of the transmission,resulting in grinding quality is not stable.With the rapid development of digital technology,especially the wide application of PLC technology and continuous improvement,high precision servo system and a wide range of touch screen control system and convenient application,the hydraulic type grinder NC transformation is possible.This paper is based on MITSUBISHI Q series PLC as the core control system,combined with MITSUBISHI servo device and touch screen equipment,the overall improvement of the hydraulic system with electric circuit system and mechanical system,so as to realize the automation of hydromechatronics inner raceway grinder.At the same time,the use of Q series programmable programming software GX Developer programming control program,especially the use of SFC programming,the device action module and process,can make the program clear,easy to maintain,and can enhance the portability and versatility.
