Cantilever type automatic-locating welder and using method thereof

Abstract

The invention discloses a cantilever type automatic-locating welder. The cantilever type automatic-locating welder comprises a horizontal guide rail base, a vertical guide rail base, a cantilever support, a cantilever assembly, a welding gun head assembly and an electric control table, wherein the vertical guide rail base moves along the X axis; the cantilever support moves on the vertical guide base along the Y-axis; under the driving of the cantilever assembly, the welding gun head assembly moves along the Z axis; and in the X-axis direction, the Y-axis direction and the Z-axis direction, awelding gun head is equipped with a proximity switch for obtaining spacing between a welding gun and an oil tank. The cantilever type welder enables the welding gun head to extend into the oil tank toweld, replaces manual work to enter the oil tank to weld, and improves welding efficiency and welding effect; three axial proximity switches are additionally arranged on the welding gun head, and onegroup of proximity switches in the same direction are staggered, so that the cantilever type welder automatically calibrates a distance between the welding head and the oil tank wall, eliminates position deviation, and guarantees welding quality.

Description

technical field [0001] The invention relates to a welding machine, in particular to a cantilever type automatic position-seeking welding machine and its use method, belonging to the field of welding machinery technology. Background technique [0002] Many existing fixed table presses are welded structures. The oil tank of the fixed table press is a rectangle with a sealed structure around it. The depth is large and the welding space is insufficient. Manual welding is difficult. At the same time, manual welding is easy to be damaged due to the narrow welding space. The high-temperature weld seam is scalded. Because the structural space of the fuel tank is not ventilated, the harmful dust generated by welding is concentrated and difficult to spread, and the working environment of the workers is harsh. The oil tank of the fixed table press is used to store oil. After the weld seam is welded, an air tightness test is required to ensure that the weld seam does not leak oil. Howev...
