Grinding force measuring method for bearing ring outer circle grinding

Abstract

The invention discloses a grinding force measuring method for bearing ring outer circle grinding. Force measuring sensors are installed on a front supporting point and a rear supporting point of an electromagnetic centerless clamp for grinding a bearing ring respectively, when the bearing ring is ground, the force measuring sensors accurately measure the supporting force borne by the bearing ring, and the normal grinding force and the tangential grinding force borne by the bearing ring in the grinding process are calculated by measuring the supporting force of the bearing ring in the two balanced states before the bearing ring is in contact with a grinding wheel and after the bearing ring is in contact with the grinding wheel for grinding. According to the scheme, indirect measurement is matched with theoretical calculation, the mode is simple, and calculation is accurate. By accurately measuring the normal grinding force and the tangential grinding force of the grinding wheel, the abrasion degree of the grinding wheel is mastered in time, the grinding amount and the finishing time of the grinding wheel are controlled, and the grinding quality and efficiency of the outer circle of the bearing ring are improved.

Description

technical field [0001] The invention relates to the technical field of cylindrical grinding of bearing rings, in particular to a method for measuring the grinding force of cylindrical grinding of bearing rings. Background technique [0002] As we all know, during the grinding process of the bearing ring, it is necessary to accurately grasp the grinding force on the ring, control the cutting amount to avoid the occurrence of grinding burns, and at the same time control the wear condition of the grinding wheel and determine the dressing of the grinding wheel time. However, when measuring the normal grinding force and tangential grinding force on the workpiece during the grinding process, in actual production equipment, it is not easy to directly install a load cell on the grinding wheel spindle to achieve direct measurement. The traditional method is to introduce the approximate calculation formula of electromagnetic attraction, and obtain the grinding force of the grinding w...

Problems solved by technology

However, there is a gap in the magnetic circuit of the solenoid coil structure, so there is a certain error in the calculated magnetic force, and the electromagnetic centerless fixture has magnetic attraction force, friction force, and radial fulcrum support force on the bearing ring. The force is more complicated, and then the calculated normal grinding force and tangential grinding force of the bearing ring will have a greater error
