Welding gun regulating device applied to welding of horizontal H-shaped steel

Abstract

The invention relates to a welding gun regulating device applied to welding of horizontal H-shaped steel and belongs to the field of machinery manufacturing equipment. The welding gun regulating device is composed of a rack, a hydraulic pushing device and a welding gun regulating mechanism. The welding gun regulating mechanism is composed of a lifting mechanism and a rotating mechanism. The lifting mechanism is matched with an operation sliding rail through a welding lifting platform and installed on the rack and the rotating mechanism is composed of a welding gun, a welding gun connection sleeve, a welding gun regulating frame and a welding gun adjusting screw rod. The top of the welding gun regulating frame of the rotating mechanism is connected with a hinge pin sleeve of the lifting mechanism in a matched mode through a hinge pin. The top end of the hinge pin sleeve of the lifting mechanism is connected with the telescopic rod end of a hydraulic oil cylinder through an abutting and pushing frame so that the welding gun can lift along with stretching and contracting of the telescopic rod of the hydraulic oil cylinder and rotate around the hinge pin relative to the welding gun lifting platform under the rotation drive of screwing the adjusting screw rod. Thus, the height and the rotation angle of the welding gun relative to the H-shaped steel can be regulated. The welding gun regulating device applied to welding of the horizontal H-shaped steel is simple in structure and can be widely applied to welding of H-shaped steel with the uniform section and varying sections.

Description

Technical field [0001] The invention relates to a welding gun adjusting device for horizontal H-shaped steel welding, which belongs to the field of mechanical manufacturing equipment. Background technique [0002] With the acceleration of industrial modernization, steel structure buildings are widely used in engineering practice due to their advantages of low construction cost, energy saving and environmental protection. Therefore, H-shaped steel as the main supporting component of steel structure buildings has attracted more and more attention from the society. The welding quality of H-beam welds directly affects its mechanical properties. The welding quality is closely related to the welding position of the welding torch. However, the adjustment of the welding torch of the existing equipment usually adopts manual adjustment of the semi-circular arc bolt to adjust the angle of the welding torch. The accuracy is also difficult to guarantee. Therefore, it is urgent to develop a w...
