Welding and positioning device for side plates of vertical and horizontal container with adjustable size

The invention relates to a size-adjustable vertical and horizontal two-type container side plate welding and positioning device, which utilizes a large number of clamps to be uniformly distributed on a container side plate so as to improve the connection stability and positioning reliability of the container side plate, and utilizes the height-adjustable clamps to enable each part of the container side plate to be flat. The welding positioning device is hinged with the base and the upper support frame through the hinge shaft, and the upper support frame is driven to rotate relative to the base by the main driving mechanism, so that the switching of the two working states of standing and lying of the welding positioning device is realized, and the problem of large welding limitation of a single mode is solved.
