Processing method of curved surface parts and processing equipment of curved surface parts

Abstract

The invention provides a curved part processing method which concretely comprises the steps that the vertex normal vectors of a curved part are confirmed before processing and then converted into position coordinate theoretical values according to a robot algorithm model; the positional relation of position calibration blocks relative to the central point of a processing tool is calibrated before processing; then a robot is moved to a processing area, and the normal vectors of the processing cutter are adjusted according to the position coordinate theoretical values; then the position calibration blocks are scanned by a three-dimensional scanning device so that the practical position values of the position calibration blocks are obtained, and then a practical position error is obtained according to the difference value between the practical position values and the theoretical values; then compensation and correction are performed on the current position coordinate values of the actuator of the robot via a control unit according to the practical position error; then the robot is enabled to perform processing on the corresponding processing area on a processing surface; and then the aforementioned steps are repeated until processing of the processing area on the processing surface is completed. The invention also provides curved part processing equipment.

Description

technical field [0001] The invention relates to the technical field of processing curved surface parts, in particular to a processing method for large-sized curved surface parts and processing equipment for curved surface parts. Background technique [0002] At present, CNC drilling or manual drilling is generally used for hole processing of large-sized curved surface parts. However, if CNC drilling is used, there are problems of large machine tool footprint and high cost; if manual processing , there are problems of low efficiency and poor accuracy. In addition, some personnel also use robot processing methods. However, the current robot processing methods have the problems of large positioning errors and low repeatability of batch workpieces. The processed curved surface parts are difficult to assemble accurately. [0003] Therefore, it is necessary to provide a technical means to solve the above defects.
