In order to solve the problems that an existing laser pendulum shaft machining system is low in machining precision and difficult to adjust, the invention provides a laser pendulum shaft light beam pointing error automatic correction method and system, and through the method and system, the problem that due to the fact that an included angle exists between a light beam and a laser pendulum shaft, the focus position is changed can be greatly solved. The method is of great significance in improving the manufacturing precision of a laser pendulum shaft machining system based on hard light path transmission. The laser pendulum shaft light beam pointing error automatic correction system comprises a laser, a first reflector, a laser pendulum shaft, a calibration plate, a reflection unit, a second reflector and a coaxial camera. According to the automatic correction method and system for the laser pendulum shaft light beam pointing error provided by the invention, the error existing in the prior art can be effectively compensated and automatically corrected; meanwhile, the system provided by the invention is simple in structure and low in cost, and can be directly transformed and upgraded on the basis of an existing structure.
Description
technical field [0001] The invention belongs to the field of laser precision manufacturing, and in particular relates to a method and a system for automatic correction of the beam pointing error of a laser pendulum axis. Background technique [0002] At present, in the laser processing of complex curved parts, the processing system using the laser pendulum axis is widely used in the processing of complex curved parts due to its large moving range, flexibility and ease of integration. [0003] This type of processing system can be roughly divided into two categories according to the laser beam transmission mode of the laser pendulum axis: [0004] 1. Optical fiber transmission method [0005] This type of laser pendulum shaft directly mounts the laser fiber on the processing head, and the optical fiber swings with the processing head during the processing, so as to realize the laser processing of the parts. The beam of this type of processing head can directly act on the pa...
