The invention discloses a tool clamp for heat exchange plate welding and a welding method using the tool clamp. The tool clamp comprises a base, a base panel, a first side edge stop block and a secondside edge stop block. The first side edge stop block is used for abutting against the first side edge of a heat exchange plate, and the second side edge stop block is used for abutting against the second side edge, adjacent to the first side edge, of the heat exchange plate. The base panel is provided with a positioning protruding block, a first air cylinder, a first pressing block, a second aircylinder and a second pressing block. The positioning protruding block is used for being clamped into a notch in the heat exchange plate located below. The first air cylinder is used for driving the first pressing block to move up and down on the second side edge of the heat exchange plate; the second air cylinder is used for driving the second pressing block to move up and down in the middle of the heat exchange plate, and the second pressing block keeps away from the notch in the heat exchange plate located above. According to the tool clamp for heat exchange plate welding, the heat exchangeplate can be conveniently positioned and welded; and according to the welding method using the tool clamp, the welding quality of the heat exchange plate can be improved.
Description
technical field [0001] The invention relates to the technical field of heat exchange equipment, in particular to a fixture for heat exchange plate welding and a welding method using the fixture. Background technique [0002] The plate heat exchanger is a high-efficiency heat exchanger composed of a series of metal plates with a certain corrugated shape. A thin rectangular channel is formed between each metal plate, and heat exchange is performed through the metal plate, and its function is to transfer the heat of one fluid to another fluid. The stacking of metal plates is an important part of the plate heat exchanger assembly process, which directly affects the heat exchange effect of the plate heat exchanger. At present, the stacking of metal sheets is generally done by manual welding, and the positioning of the metal sheets is lacking during manual welding, so that it is impossible to align the two metal sheets every time they need to be welded, so that the welding qualit...
