Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] like Figure 1-7 As shown in , a method for real-time automatic tracking of weld seams for large and complex box-shaped structural parts adopts the following steps:

[0029] ①, (refer to figure 1 ) Assemble the flat plate 1, backing plate 2, curved plate 3, pasting plate 4, straight plate 5 and functional components 6 into a grid structure according to the production requirements of large and complex box-shaped structural parts.

[0030] ②, (refer to image 3 ) Place the assembled large complex box-shaped grid structure 14 on the automatic welding station 15, start the inner cavity automatic welding equipment 13, and the welding torch 8 configured on it automatically finds the starting point of the weld according to the preset welding program; Simultaneously, the swinging striker 12 installed at the end of the welding torch begins to swing obliquely repeate...

Abstract

The invention relates to the field of welding and processing of structural parts, in particular to a welding seam automatic tracking method for a large-sized complex box-shaped structural part. The invention solves the problem that an existing welding seam automatic tracking technology cannot adapt to high-temperature arc light smoke as well as the narrow space limit of a box-shaped square check and the unified tracking requirements of a plurality of welding seam types and overcomes the defect of low online effective utilization rate of automatic welding equipment. The method comprises the following steps: (1) placing the large-sized complex box-shaped structural part formed by assembly on an automatic welding workstation; (2) mounting a swinging firing pin at the end part of a welding torch of the automatic welding equipment, repeatedly swinging and colliding the two sides of each of welding seams through the firing pin to feed back welding seam swinging amplitude information; (3) comparing with set theoretical swinging amplitude through an equipment control system and calculating a swinging amplitude difference value; (4) adjusting the posture of the welding torch to an accurate position according to the swinging amplitude difference value, arcing and welding till automatic tracking and welding of all the welding seams of the structural part is completed. The welding seam automatic tracking method provided by the invention is reasonable and brief in process, strong in maneuverability and high in production efficiency, ensures the welding quality and is suitable for wide popularization.

Description

technical field [0001] The invention relates to the field of welding processing of structural parts, in particular to a real-time automatic tracking method for welding seams of large and complex box-shaped structural parts. Background technique [0002] The medium-thick plate structural parts with grid-shaped structural characteristics composed of special-shaped curved plates, straight plates, pasted plates, backing plates, cover plates and various functional moldings are called large complex box-shaped structural parts, which are usually composed of The welding process is complete. Due to the existence of special-shaped structures, the forming process includes trimming and matching, resulting in errors in assembly, resulting in changes in the position and size of the weld. When automatic welding is used, the weld trajectory needs to be guided and tracked in advance. The known welding seam tracking technology can be divided into two categories: external tracking sensor equi...
