Abstract

The invention discloses an automatic grinding constant-pressure control method based on a PLC. The method comprises the steps that required grinding rotating speed and required grinding pressure of ato-be-ground object are set; a control instruction is generated according to the required grinding rotating speed and the required grinding pressure, and a grinding wheel mechanism operates accordingto the control instruction; actual pressure of the grinding wheel mechanism is calculated according to actual output current of a grinding wheel frequency converter; the required grinding pressure iscompared with the actual pressure, and a pressure compensation value is obtained according to a comparison result; when the pressure compensation value exceeds a preset range, compensation parameterscorresponding to the pressure compensation value are obtained through recognition according to positive and negative values of the pressure compensation value and a numerical value interval where thepressure compensation value is located, wherein the compensation parameters comprise a compensation direction and actual compensation rotating speed; and a compensation mechanism is controlled to operate according to the compensation direction and the actual compensation rotating speed to grind the to-be-ground object. According to the automatic grinding constant-pressure control method based on the PLC, the grinding effect of the ground product can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of automatic mechanical equipment, in particular to a PLC-based automatic grinding constant pressure control method and system. Background technique [0002] As an important technical link in the field of modern workpiece surface processing, grinding and polishing technology reduces the surface roughness of the workpiece through grinding equipment to obtain a bright and smooth surface. The existing automatic grinding constant pressure control method keeps the grinding pressure constant through pneumatic control, specifically by obtaining the pressure change value during grinding and adjusting the push force of the cylinder according to the pressure change value to keep the grinding pressure constant. [0003] Grinding with the existing automatic grinding control method has the following problems: [0004] Poor adaptability, when the grinding trajectory or workpiece appearance deviates greatly, the grinding ...
