Weld joint milling back gouging robot with high precision and low residual stress

Abstract

The invention relates to the technical field of milling back gouging robots, and discloses a weld joint milling back gouging robot with high precision and low residual stress. The weld joint milling back gouging robot comprises a lathe bed, a sliding table, a stand column, a 6PUS parallel structure, a cutter head, a motion control system and a groove detection system. The sliding table is movably installed on the lathe bed, and the stand column is fixedly installed on the sliding table; the 6PUS parallel structure is fixedly installed on the stand column, and the cutter head is installed on the 6PUS parallel structure. According to the weld joint milling back gouging robot with high precision and low residual stress, developed through absorption and introduction of a new technology, a new process and integrated innovation, the problems that weld joint cleaning cannot be automatic, the working environment is poor, the cleaning quality is poor, and residual stress is high are solved; the blank in the field of automatic back gouging of weld joints in China is filled up, and meanwhile the residual internal stress of the weld joints is greatly reduced through a flexible milling back gouging cold machining process; the labor intensity is reduced, and the problems of environmental pollution of sound, light and dust due to carbon arc gouging, polishing and other processes are solved; and the construction environment is improved.

Description

technical field [0001] The invention relates to the technical field of milling root cleaning robots, in particular to a milling root cleaning robot with high precision and low residual stress. Background technique [0002] The current welding seam cleaning technology has the problems of inability to automate, poor working environment, poor cleaning quality, and high residual stress. Moreover, the field of automatic welding seam root cleaning is basically blank in China. The labor intensity of workers is increased during weld seam cleaning, and at the same time The environmental pollution problems of sound, light and dust caused by carbon arc gouging, grinding and other processes during welding seam cleaning have not been well resolved. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the invention provides a welding seam milling and cleaning robot with high precision and low residual stress. [0005] (...
