Description

Technical Field

[0001] The utility model belongs to the technical field of steel member processing, and relates to a weld treatment device, in particular to a weld treatment device for steel structure members. Background Technique

[0002] A weld is a seam formed by melting and connecting the electrode and the metal at the joint using the high temperature of the welding heat source. After the weld metal cools, the two welded parts are joined into a whole. According to the shape of the weld metal and the different positions of the welded parts, there are butt welds, fillet welds, plug welds, and electric rivet welds, etc. Butt welds are commonly used for splicing plates and sections; fillet welds are commonly used for lap joints; plug welds and electric rivet welds are less used and are only considered to reduce the lap length of the welded parts.

[0003] After retrieval, as disclosed in a Chinese patent document, there is a heat treatment device for austenitic stainless steel welds [Application No.: 202320599729.X; Publication No.: CN 219358968 U]. This metal component weld positioning and grinding device includes a machine table main body. A positioning groove for fixing the fixture is centrally opened at the top of the machine table main body, and chutes are centrally opened at the top of both sides of the machine table main body. Threaded rods are rotatably arranged in both chutes, and one end of the threaded rod extending out of the chute is connected to a servo motor I fixed to one side of the machine table main body. A grinding component is commonly installed in a threaded fit on the two threaded rods. The grinding component includes two sliding components respectively installed in a threaded fit on the two threaded rods. A lifting drive component is commonly constructed at the top of the two sliding components, and a support plate is fixedly installed between the two lifting drive components. This metal component weld positioning and grinding device does not require manual holding, is time-saving and labor-saving during grinding, can continuously grind the workpiece, has a high grinding efficiency, and has strong practicability.

[0004] Although the positioning groove disclosed in this patent, this metal component weld positioning and grinding device does not require manual holding, is time-saving and labor-saving during grinding, can continuously grind the workpiece, has a high grinding efficiency, and has strong practicability. However, during the process of grinding the weld, the fixture cannot be adjusted according to the length and width of the steel plate to fix the steel plate in all directions of front, back, left, and right, and the situation of steel plate displacement may occur, which easily leads to grinding errors.
