Abstract

The invention discloses a PLC-based automatic grinding constant pressure control method, comprising: setting the required grinding speed and the required grinding pressure of the object to be polished; generating a control instruction according to the required grinding speed and the required grinding pressure, so that the grinding wheel The mechanism operates according to the control command; the actual pressure of the grinding wheel mechanism is calculated according to the actual output current of the grinding wheel inverter; the required grinding pressure is compared with the actual pressure, and the pressure compensation value is obtained according to the comparison result; when the pressure compensation value exceeds the preset range , according to the positive and negative values ​​of the pressure compensation value and the value interval of the pressure compensation value, the compensation parameters corresponding to the pressure compensation value are identified, and the compensation parameters include the compensation direction and the actual compensation speed; the control compensation mechanism is based on the compensation direction and the actual compensation Run at high speed to grind the object to be polished. The invention provides a PLC-based automatic grinding constant pressure control method, which can effectively improve the grinding effect of grinding products.

Description

Technical field [0001] The present invention relates to the field of automated mechanical equipment, and more particularly to a PLC-based automatic polishing constant voltage control method and system. Background technique [0002] Polishing technology is an important technical link in the field of modern workpiece surface processing treatment, and the surface roughness of the workpiece is lowered by the grinding device to obtain bright and flat surfaces. The existing automatic polishing constant pressure control method maintains the grinding pressure constant by pneumatic control, specifically by acquiring the pressure change value at the time of grinding, and maintains the grinding pressure constant according to the pressure change value to adjust the cylinder. [0003] Working with existing automatic polishing control methods, there is the following problems: [0004] When the adaptability is poor, the grinding trajectory or workpiece has a large deviation of the grinding pres...
