Grinding machining method and device

Abstract

The invention provides a grinding machining method. The grinding machining method comprises the steps that 1, 3D data of a to-be-machined workpiece are acquired; 2, the acquired 3D data and standard 3D data are matched through a computer, and a defective portion is obtained; and 3, the defective portion is machined and ground repeatedly through a machining laser. The invention further provides a grinding machining device. The grinding machining device comprises a robot, 3D imaging equipment, the machining laser and the computer; the robot drives a tool to drive the to-be-machined workpiece todo linear motion on the y axis in the longitudinal direction of the workpiece, 3D point cloud data of the whole workpiece are acquired through the 3D imaging equipment and matched with the standard 3Ddata, and the defective portion is obtained; and the robot moves to the machining position in the y-axis direction, and the machining laser machines and grinds the defective portion repeatedly. According to the technical scheme, full automation is achieved, manpower is saved, pneumoconiosis is eliminated, a large amount of labor cost is reduced, the machining speed is high, and the efficiency ishigh.

Description

technical field [0001] The invention relates to a grinding processing method and device, belonging to the field of grinding processing of special-shaped parts. Background technique [0002] In the occasion of grinding and processing special-shaped parts, the existing method is to use manual grinding. The most typical case is that in the case of mold repair, workers use sub-arc welding to make up for the missing parts, and then use the fitter to manually grind off the excess parts. The fitter needs to evaluate the grinding situation while grinding to ensure the mold. High precision requirements. It takes an average of three years for a fitter to grow up and be able to operate independently. The cost is very high, and there are health problems such as pneumoconiosis. However, if mechanical automatic grinding is developed, it is very difficult to use sandpaper or grinding wheels due to the special-shaped structure, and the lack of sensor methods for evaluation makes it diffic...
