Method and device for constant pressure polishing of glass periphery

Abstract

The invention discloses a constant pressure polishing method and device for glass periphery. The present invention obtains the unit vector of the machining direction according to the machining path and the current position of the polishing wheel, obtains the unit vector of the pressure compensation direction according to the unit vector of the machining direction, collects the torque data of the spindle drive, and based on the PID control algorithm, according to the preset Comparing the torque data and torque data, the pressure compensation increment of the polishing wheel is obtained. According to the unit vector of the pressure compensation direction and the sum of all pressure compensation increments under the current wear compensation cycle, the position compensation increment of the polishing wheel is obtained. The position compensation increment controls the adjustment of the polishing wheel from the current position to the compensated position, so that the polishing wheel polishes the glass at the compensated position, and repeats the above operations until the polishing of the glass is completed. Constant pressure polishing improves polishing quality on the premise of ensuring machining accuracy.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a constant pressure polishing method and device for the periphery of glass. Background technique [0002] During the polishing process of the glass periphery, the polishing wheel is easily worn, resulting in that the polishing wheel can abut the glass periphery for polishing in the early stage of processing, and the polishing wheel cannot abut the glass periphery for polishing in the later stage of processing, which reduces the processing accuracy. In order to solve the problem of polishing wheel wear, the commonly used polishing wheel wear compensation method is to add a pressure cylinder to the mechanical structure, and use the pressure cylinder to abut the polishing wheel against the periphery of the glass for polishing. However, in practical applications, the use of mechanical means to compensate for the wear of the polishing wheel increases the complexity of the pro...
