Description

Technical field: [0001] The invention relates to a rectangular coordinate type submerged arc welding robot. Background technique: [0002] Welding, also known as welding, is a manufacturing process and technique that uses heat, high temperature, or pressure to join metal or other thermoplastic materials such as plastics. [0003] There are many sources of energy for modern welding, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasonic waves; in addition to being used in factories, welding can also be performed in a variety of environments, such as field, underwater, and space; Welding, wherever it occurs, can pose a hazard to the operator, so proper precautions must be taken when welding. [0004] At present, there is a huge demand for long straight seam welding in the steel structure industry.

Problems solved by technology

[0004] At present, there is a huge demand for long straight seam welding in the steel structure industry. The characteristics of the workpiece are long weld seam, many types, difficult to guarantee blanking deviation and assembly deviation, and thermal deformation during the welding process. The above characteristics make it difficult to implement automatic welding methods. , so manual hand-held welding is the main method, but manual welding has low production efficiency, poor weld seam consistency, and requires high welding skills and even physical strength for welders. The existing special welding machines are complex to operate, single-targeted, and low in automation and intelligence; At the same time, most of the existing industrial welding robots are articulated structures, composed of rotational degrees of freedom, and the spatial posture of the welding torch is flexible. It is suitable for workpieces with complex shapes and many curved surfaces in space. 6Kg, the rigidity of the mechanical arm is relatively weak, which is more suitable for the installation of light welding torches such as gas shielded welding. For submerged arc welding, it is difficult to carry the weight of welding torches, wire feeders, and flux funnels. In addition, it is difficult to control the movement of articulated robots. It is suitable for use in a large area and in a large space, and the cost is relatively high. It is difficult to solve the welding seam deviation and thermal deformation of the welding process.
