Welding special machine for short pipe-flange and pipe-pipe pieces

Abstract

The invention relates to a welding special machine for short pipe-flange and pipe-pipe pieces, and the welding special machine comprises a power head and a roller wheel rack with a gun rack, wherein the roller wheel rack with the gun rack is installed on a power head rack through a pulley; the front end of the power head clamps a workpiece through a clamping disc; the upper parts of the front andrear sides of the roller wheel rack with the gun rack are respectively provided with an operation box and an aluminum section bracket; a transverse shift sliding rack is fixed to the aluminum sectionbracket; a servo cross sliding rack is installed on the transverse shift sliding rack; a rotating angle mechanism is installed on a horizontal sliding rack arranged in the servo cross sliding rack; the front end of the servo cross sliding rack is fixed with a welding gun through a rotating arm mechanism; and the welding gun is connected with a control system through a pipeline. The welding gun can adjust the welding angles in the axial direction and in the front-rear direction, and the automatic lifting and swinging can be realized through the transverse shift sliding rack and the servo crosssliding rack. According to the invention, the automatic welding of butt joint welding seams and angle joint welding seams can be realized, and the welded filling cover surface is finished at one step, thereby improving the welding efficiency and simultaneously guaranteeing the welding quality.

Description

technical field [0001] The invention belongs to the field of welding devices, in particular to a short pipe-flange and pipe-pipe fitting welding machine. Background technique [0002] Existing welding of pipe fittings, including pipe-pipe butt joints, pipe-flange corner joints, etc., often requires manual work and separate processes to achieve bottoming, filling, and covering, and the efficiency is low; the workpiece is prone to rotation in the welding process. Stability, eccentric load, axial movement and other conditions will affect the quality of the workpiece; it is difficult to weld large-diameter workpieces. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a short pipe-flange and pipe-pipe fitting welding machine to realize automatic welding of pipe-pipe butt joint and pipe-flange fillet joint, and complete welding of bottoming, filling and capping at one time. To improve welding quality and efficiency. ...
