Welding method

Abstract

The invention discloses a welding method. A welding device is used for welding a workpiece; and the welding method comprises the steps that (1) the workpiece is conveyed, wherein a mechanical hand air pressure rod is used for controlling a mechanical hand to grab the workpiece, a motor continuously drives a lead screw to move, a mechanical hand installing base reaches the position above a lower pressing block, and the height of the mechanical hand installing base is larger than that of an upper pressing block; (2) the workpeice is clamped, wherein a raising block extends to the appropriate position so as to enable the height of the lower pressing block to be larger than that of the upper pressing block, the lower pressing block is in contact with the bottom face of the workpeice, the mechanical hand air pressure rod is used for controlling the mechanical hand to release the workpiece, the mechanical hand installing base returns along the original way, a rotating rod rotates to the appropriate angle, and therefore the workpiece can avoid the lower pressing block to downwards move, the raising block contracts back to the original height, a lifting rod rises to the appropriate height and is higher than the workpiece, the rotating rod then rotates to the appropriate angle, the side portion of the workpiece can be just located above the upper pressing block, the air pressure rod is clamped to push a push block, and clamping is carried out through the upper pressing block; and (3) welding is carried out.

Description

Technical field: [0001] The invention relates to the field of processing technology, in particular to a welding method. Background technique: [0002] At present, the development of steel or other materials will put forward newer, higher and more requirements in many aspects such as welding technology and its process, consumables, equipment, automation, efficiency, cost, life, maintenance, and remanufacturing. Welding methods are developed complementary to each other under the impetus of the development of modern industry and science and technology. It can be predicted that with the continuous development of modern industry and science and technology, there will be new developments in welding technology and equipment. Therefore, welding fixtures are widely used. However, the existing welding fixtures have some disadvantages during use. First, the size of the fixture itself is fixed, but the metal materials to be welded are of different sizes, so often there will be inconsi...

AI Technical Summary

Problems solved by technology

However, the existing welding fixtures have some disadvantages during use. First, the size of the fixture itself is fixed, but the metal materials to be welded are of different sizes, so often there will be inconsistency between the fixtures. This will directly affect the efficiency of work and the quality of products; secondly, most of the existing fixtures only limit a single degree of freedom. When clamping materials on curved surfaces, there will often be a little slip, but This greatly affects the welding effect and reduces the accuracy of the product
