Abstract
Welding positioner is a kind of welding auxiliary equipment, it was known as the three planes in welding auxiliary equipment with welding manipulator, welding roller bed. Welding positioner was designed with the development of welding industry mechanization, and automation. As a welding auxiliary machine, welding positioner was used in pipe′s landscape orientation welding, pipe and flange′s inside and outside central linking welding, pipe welding in all location. Though the gyration and retroflexion of the workbench, the welding positioner can make the welding line to an ideal position, which can improve the quality of the welded joint, reduce welder’s workload. It is ideal equipment especially fit to weld the kinds of workpiece, just like the shaft, tray, canister, and so on.
By understanding the welding positioner′ s development in domestic and overseas, and the positioner used in welding robot is described in the paper. A block 60 ton s of welding positioner is designed.Mainly on the subject of welding ,mechanical rotation turnover of control, the electrical options, reducer selection, various axle and the wheel bearings and determine accuracy ,and so on.
The design process is based on specific target load and speed requirements of welding equipment to determine the type of electrical needs, including: the rotational speed electrical, rated power, voltage, current and on the basis of the calculation of axle size and corresponding accessories models, and their associated intensity, and the useful life of accuracy, then for some purchases were also chosen.
The method chosen mainly mechanical design relevant knowledge, the use of the material mechanics, CAD.
