Welding tool clamp for machining

The utility model discloses a welding tool clamp for machining, and belongs to the technical field of tool clamps. Comprising a bottom plate, a first stud is fixedly arranged in the middle of one side of the upper surface of the bottom plate, two sleeve plates with variable included angles are rotatably connected to the first stud, telescopic plates are slidably connected to inner cavities of the ends of the two sleeve plates, notches are formed in the ends of the two telescopic plates, and L-shaped plates are fixedly connected to the side walls of the notches; the welding device is simple in structure and convenient to operate, two workpieces can be welded at different angles due to the fact that the two sleeve plates are connected in a rotating mode, and different positions of one workpiece and different positions of the other workpiece can be welded together in a contact mode by adjusting the length of the telescopic plate. The flexibility of the welding tool clamp is greatly improved. 本实用新型公开了一种用于机械加工的焊接工
