Plane grinding device for measuring grinding pressure in real time and pressure regulation and control method thereof

Abstract

The invention provides a plane grinding device for measuring grinding pressure in real time and a pressure regulation and control method thereof. The plane grinding device comprises a longitudinal moving structure, a transverse moving structure, a grinding structure and a real-time measuring structure, wherein the longitudinal moving structure comprises a cross beam, a sliding rail motor and a machine tool frame, the sliding rail motor is fixedly installed in a top groove of the machine tool frame through a supporting block, and the cross beam is fixedly connected between the side walls of sliding blocks of the sliding rail motor. According to the plane grinding device for measuring the grinding pressure in real time and the pressure regulation and control method thereof, on the premise that a workpiece and a grinding wheel do not need to be damaged, the magnitude of the grinding force can be measured in real time in the grinding process by utilizing a dynamometer, meanwhile, when the measured grinding force is larger than a calibrated value, an industrial personal computer can control hydraulic cylinders on the two sides of a grinding head to reduce the pressure between the grinding wheel and the workpiece, so that the deformation of a process system caused by too high grinding force is prevented, and the plane grinding machining precision of large-scale parts is improved.

Description

technical field [0001] The invention relates to the technical field of grinding processing, in particular to a surface grinding device for real-time measurement of grinding pressure and a pressure control method thereof.

Problems solved by technology

In the surface grinding of large-scale parts, due to the large size of the parts, it is easy to cause large differences in the surface roughness values ​​of various parts on the surface of the parts due to the different grinding forces in various parts of the parts, and the machining accuracy is difficult to control

In the existing research, most of the research is on the cutting force of outer circle cutting, and there is no processing device that can measure the grinding force in real time and respond quickly to the surface grinding of large-scale parts.
