Abstract

The invention discloses a metal rotating member constant-pressure grinding control device and method. The device comprises a grinding wheel, a grinding wheel driving motor, a workbench, a servo motor, a reducer, a frequency converter and a grinding control system. The grinding wheel is directly driven by the grinding wheel driving motor which is arranged on the workbench. The workbench is mounted on two linear guide rails. The lower portion of the workbench is further connected with a nut of a lead screw-nut transmission pair. A lead screw of the lead screw-nut transmission pair is driven by the servo motor and the reducer, and rotation of the servo motor is transmitted to the workbench through the lead screw-nut transmission pair. The frequency converter is connected with the grinding wheel and controls the rotation speed of the grinding wheel. A current sensor is arranged in the position of an input power source of the grinding wheel driving motor and samples working current of the grinding wheel driving motor according to a set time period. The convergence of parameters can be better controlled, and meanwhile the device and method have the advantages of being more stable in control and better in grinding quality.

Description

technical field [0001] The invention relates to an automatic control method for grinding metal rotary parts, more specifically, it relates to a constant pressure grinding control device and control method for metal rotary parts. Background technique [0002] Grinding is the most commonly used surface finishing process for hardware. All kinds of stainless steel kitchen utensils, stainless steel daily necessities, metal building materials and decorations, automobile wheels and other parts need to be polished to reduce the surface roughness of the parts and improve the appearance quality of the parts surface. At present, the grinding and polishing of hardware parts generally adopts manual and semi-mechanized operations. The workers have high work intensity, low production efficiency, and poor product quality stability. More importantly, the grinding production environment is harsh, and the metal dust generated during the grinding process is harmful to the health of workers The...
