Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal clamps, in particular to a sheet metal welding clamp. Background Art

[0002] The main purpose of sheet metal welding fixtures is to fix and position sheet metal parts during welding to ensure welding quality and efficiency. It can accurately fix sheet metal parts in the required position and prevent them from moving or deforming during other welding processes. Although the use of sheet metal welding fixtures may increase the complexity of welding, they provide many advantages. For example, they can provide more precise positioning, reduce welding deformation, improve production efficiency and reduce the requirements for operator skills.

[0003] A Chinese patent publication (publication number: CN220362191U) discloses a sheet metal welding fixture, which includes a working platform and a fixture unit, and the fixture unit is installed on the upper end of the working platform in a left-right symmetrical shape. When in use, the output shaft of the cylinder can be used to push out the clamping end, so that the clamping end can clamp the sheet metal. The movable plate is first pressed against the upper and lower surfaces of the sheet metal, and during continuous clamping, the movable plate will gradually align with the block, and the sheet metal is fixed through the sides of the two. Because there is a spring between the side of the movable plate and the fixed plate, When the movable resist plate is squeezed, the spring will be pulled. When the resist block is flush with the side of the movable resist plate and resists against the surface of the sheet metal, the spring will continue to contract and cause the movable resist plate to tilt. Therefore, the movable resist plate can swing with the connection end between it and the resist block as a fulcrum, so that the upper part of the movable resist plate is squeezed toward the sheet metal, thereby increasing the fixing effect of the sheet metal. However, during use, it is not convenient to adjust the position of the clamp, so that when clamping sheet metal workpieces of different specifications, the clamp in the fixed position has high limitations, which reduces the use effect of the clamp. For this reason, a sheet metal welding clamp is proposed. Utility Model Content
