Welding clamp

Abstract

The invention relates to a welding clamp. The welding clamp comprises a first supporting plate and a second supporting plate, wherein the first supporting plate and the second supporting plate are connected in a pivoted mode, an arc-shaped angle positioning plate is arranged between the first supporting plate and the second supporting plate, one end of the angle positioning plate is fixed to the first supporting plate, the other end of the angle positioning plate penetrates through the second supporting plate, the radian of the angle positioning plate is 180 degrees, and the first supporting plate and the second supporting plate are respectively connected with a clamping device for locking a workpiece to be welded in a sliding mode. According to the welding clamp, the included angle between two workpieces is adjusted through the first supporting plate capable of rotating relatively or the second supporting plate capable of rotating relatively, angle positioning is carried out through the angle positioning plate, and the included angle between the two workpieces is made to meet the welding requirement; the distance between welding edges of the two workpieces are adjusted through the sliding clamping devices to meet the requirements for the welding angle and the welding joint height; the welding clamp is simple in structure, is easy and convenient to operate and largely reduces production and machining cost.

Description

technical field [0001] The invention relates to a clamp for welding, in particular to a clamp which can clamp a workpiece at any angle for welding. Background technique [0002] Welding, also known as welding or welding, is a manufacturing process and technology for joining metals or other thermoplastic materials such as plastics by heating. The welding between the metal plates is to use the welding rod to weld between the two metal plates. After cooling and shrinking, the two metal plates can be combined. During the welding process, the two metal plates to be welded usually need to be welded by tooling or fixture fixed for soldering. The existing tooling or fixture only fixes the metal plate in a single way. For two metal plates that need to be welded into different angles and different weld heights, the existing tooling or fixture cannot adjust the clamping between the two metal plates arbitrarily. Angle, and the distance between the edges of the two metal plates can...

Problems solved by technology

The existing tooling or fixture only fixes the metal plate in a single way. For two metal plates that need to be welded into different angles and different weld heights, the existing tooling or fixture cannot adjust the clamping between the two metal plates arbitrarily. Angle, and the distance between the edges of the two metal plates cannot be adjusted (that is, the weld can only be welded into one height), which is not practical; at the same time, if you want to weld into different angles and different weld heights, you need to use multiple Tooling or fixtures increase production and processing costs
