Flexible assembling and welding workstation for finned radiator for transformer and production method

Abstract

The invention discloses a flexible assembling and welding workstation for a finned radiator for a transformer and a production method, and relates to the technical field of finned radiators. The workstation comprises a supporting frame (1), a robot external shaft (2), a welding robot and welding gun (3), a centering sliding table (4), follow-up calipers (5) and a positioning comb plate (6), a flexible assembly welding production method is adopted, the robot external shaft (2), the centering sliding table (4) and the follow-up calipers (5) use the same track, the purpose of consistent foundation is achieved, and the positioning comb plate (6) can be compatible with conveying modes such as a conveying vehicle, a hoisting mode and a truss mode. According to the flexible assembling and welding workstation, according to the production mode and the process method of an existing finned radiator, the flexible assembly welding of finned radiator unit pieces and an oil collecting pipe is automatically upgraded, so that the problem of high manual labor intensity in a field production mode is solved, and the consistency of the welding quality of the unit pieces and the oil collecting pipe is also improved.

Description

technical field [0001] The invention belongs to the field of finned radiator processing and manufacturing, and specifically relates to a flexible assembly and welding workstation for a transformer-used finned radiator and a production method, which is the core function of the assembly and welding of the finned radiator unit and the oil collecting pipe and its forward and backward carrying sequence part. Background technique [0002] At present, the industry of sheet radiators for power transformers has been developed in my country for decades. At present, the assembly and welding process of the radiators and collectors is as follows: before welding, the radiators are manually placed in the multi-piece transfer spreader, and the crane is controlled by a human. Lift the cooling fins in the multi-piece transfer spreader into the assembly station frame, remove the vacant multi-piece transfer spreader by the human-controlled crane, put the hand-held oil collection pipe into the oi...

Problems solved by technology

[0003] For example, the Chinese Utility Model Patent No. CN 206286689 U discloses "an automatic welding equipment for finned radiator header". Only the welding step is used to realize automatic welding. The core of this scheme still adopts the backward technology that has been used for many years in the industry, which cannot meet the requirements of the automation and informationization of the process equipment and the automatic transfer of workpieces in the automatic production line of the whole process of radiator manufacturing. Moreover, the welding actuator on each side of the equipment can only be rotated and welded around the axis of the oil collecting pipe coaxial with the oil collecting pipe flange positioning mechanism, and cannot weld the gooseneck radiator, which is the current mainstream product in the industry, so , the device has a single and limited function, and has low use value, so it cannot become an applicable technical solution for the transformation and upgrading of intelligent manufacturing in the industry

[0004] Another example, the announcement number is: CN 107971601 A Chinese invention patent discloses "a kind of automatic welding system and welding method for oil collecting pipe of fin radiator". The beam structure and the lateral positioning notch of the heat sink fixed on the beam completely cover the weld seam of the upper straight section of the oil collection pipe and the weld seam of the lower straight section of the oil collection pipe in the large flanged radiator, making it impossible to realize the large flanged radiator welding;

[0005] To sum up, the assembly and welding process of radiator fins and collectors in the industry of fin radiators for power transformers still adopts a relatively backward production method, with low production efficiency and poor compatibility. The existing discrete production mode of fin radiators has Seriously restrict the development of the industry
