The invention discloses a lathe-based semi-automatic welding device for welding <=400mm roll shaft equipment. The device comprises an adjustable clamping mechanism used for clamping a welding gun, andthe welding gun is made to weld the roll shaft equipment. The adjustable clamping mechanism comprises a frame body, a clamping rod, an adjusting connecting sleeve, an adjusting connecting rod, an adjusting bolt and a welding gun clamping sleeve, wherein the lower end of the frame body is fixedly connected to a machine tool, the clamping rod is composed of a cubic clamping part and a cylindrical connecting part which are integrally connected, the adjusting connecting sleeve is of an annular structure and is arranged on the connecting part in a sleeving mode, a first fixing hole is formed in the side wall of the adjusting connecting sleeve, one end of the adjusting connecting rod is fixedly connected to the side wall of the adjusting connecting sleeve, one end of the adjusting bolt penetrates through the first fixing hole to abut against the connecting part of the clamping rod to fix the adjusting connecting sleeve and the adjusting connecting rod, the welding gun clamping sleeve is mounted at the other end of the adjusting connecting rod, and the welding gun is clamped in the welding gun clamping sleeve. The device is simple in structure, the machine tool is slightly changed, original lubrication and internal transmission of the machine tool are not changed, and the welding function can be easily achieved.
Description
technical field [0001] The invention belongs to the field of semi-automatic welding, in particular to a semi-automatic welding device based on a lathe and used for welding rollers with a diameter of less than 400mm. Background technique [0002] Welding, also known as welding, is a manufacturing process and technique that uses heat, high temperature, or pressure to join metal or other thermoplastic materials such as plastics. There are many sources of energy for modern welding, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. In addition to its use in factories, welding can also be performed in a variety of environments, such as in the field, underwater and in space. Welding, wherever it occurs, can pose a hazard to the operator, so proper precautions must be taken when welding. Possible injuries caused by welding to the human body include burns, electric shock, visual impairment, inhalation of toxic gases, and excessive ultraviolet ra...
