Embodiment Construction

[0018] A constant-speed scanning and positioning post-weld seam tracking and residual stress relief system, including mobile welding equipment 1 for welding seams, a welding stress relief mobile robot 2 for eliminating welding stress, and a synchronous motor 3 fixedly placed on the Outside the weld seam, take the shaft center of the synchronous motor as the reference point; two reflective ranging sensors 4 and 5 are fixed on the motor shaft and rotate coaxially with the motor, and there is a distance between the two sensors; at the initial welding point, moving There are reflective sheets 6 (reflective sheet C), 7 (reflective sheet D), 8 (reflective sheet A), 9 (reflective sheet B ), with the distance measuring sensor mentioned above, one of the distance measuring sensors respectively detects the distance between the reference point and the welding initial point, the reference point and the welding nozzle, and the other distance measuring sensor respectively detects the referen...

Abstract

The invention discloses a constant-speed scanning positioning type post-welding seam tracking and residual stress removal system, which comprises mobile welding equipment, a welding stress removal moving robot, a synchronous motor and two reflection-type distance measuring sensors, wherein the mobile welding equipment is used for welding a welding seam, the welding stress removal moving robot is used for removing welding stress, the synchronous motor is fixedly arranged outside the welding seam and takes the axis of a synchronous motor rotation shaft as a reference point, the two reflection-type distance measuring sensors are fixed on a motor shaft, coaxially rotates with the motor and are arranged at intervals, and reflecting sheets are glued at a welding initial point, a welding nozzle of the mobile welding equipment and the operating tail end of the welding stress removal moving robot. The constant-speed scanning positioning type post-welding seam tracking and residual stress removal system is simple in structure, high in automation and high in post-welding seam tracking precision, and is free from influence of welding slag or welding defect on a post-welding seam.

Description

technical field [0001] The invention relates to an automatic control system for welding stress relief, which belongs to the technical field of sensing and measurement and control. Background technique [0002] In the fields of large structural parts welding, thin plate welding, dissimilar metal welding, superalloy welding, and high-precision special equipment welding, welding deformation needs to be effectively controlled, otherwise it will affect the size and shape of the welded parts, and will reduce the structure. Carrying capacity. For example, in the aluminum alloy shipbuilding industry, due to the large heat input during the welding process, the plate is deformed greatly and the performance of the welded joint is poor. When building a hull, about 25% of the work is shaping and hammering the planks to achieve the required flatness and curvature so that the planks can be held together. This not only affects the efficiency of ship production, but also greatly reduces th...
