Welding seam tracking method for pressing roller welding

Abstract

The invention discloses a welding seam tracking method for suppressing roller welding. The welding seam tracking method is based on a welding seam tracking system of a two-dimensional laser sensing assembly, the two-dimensional laser sensing assembly acquires deviation data in real time and processes the deviation data in an array by adopting a first-in first-out storage algorithm and a comparison compensation mode. By adopting the first-in first-out data storage algorithm and the comparison compensation mode, the running paths of a welding gun on the Z axis and the Y axis can be tracked and compensated in real time, so that each welding step of the welding gun is compensated and corrected, the distance between the welding gun and a welding seam is ensured to be a specific height, the welding gun is also ensured to move along the welding seam, the phenomenon that an existing welding gun is prone to deviating from the welding seam in the welding process, so that the welding seam straightness and the suppression roundness deviate is avoided, meanwhile, intelligent welding of the suppression roller welding seam is achieved through the welding seam tracking method, manual participation does not need, and the problems that manual welding is low in efficiency, poor in quality, high in labor intensity, low in automation degree, harmful to human bodies and the like are solved.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a welding seam tracking method for pressure roller welding. Background technique [0002] Xinjiang is a large agricultural province and also a major province of agricultural machinery manufacturing. Manufacturing is the main body of the national economy, the foundation of the country, the tool of rejuvenating the country, and the foundation of a strong country. Therefore, the agricultural machinery manufacturing industry is also a top priority in Xinjiang. For example, the use of The mechanical equipment with seeding function needs to use the pressure roller when sowing. The main purpose of using the pressure roller is to use its own gravity or external pressure to compact the soil after sowing, so that the soil density increases to facilitate the maintenance of soil moisture. to facilitate seed germination. [0003] The existing pressure roller usually includes a pressure roll...

Problems solved by technology

[0004] In order to solve the above problems, the present application provides a welding seam tracking method for the welding of the suppression roller, which can solve the existing problems of low intelligence, great harm to the human body, low efficiency and easy welding of the suppression roller 8. There is a problem of deviation between the straightness of the weld seam and the roundness of the pressure roller. At the same time, this method can be used to correct and compensate each step of the welding torch during the welding process of the pressure roller, which improves the compensation accuracy and meets the welding requirements of the roller. need
