Embodiment 1

[0014] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the roller frame 8 with a gun frame is composed of a mobile trolley, a self-centering roller frame 10, an aluminum profile support 11, a servo cross carriage 4, a traverse carriage 5, a pivoting arm mechanism 9 and a welding torch 3 mechanism and the like. The equipment is light in weight, can be moved horizontally on the guide rail, and is equipped with a locking mechanism to meet the needs of welding pipes of different lengths.

[0015] The self-centering roller frame 10 is fixed on the mobile base, which can clamp workpieces with a pipe diameter of Φ108-Φ630mm, while ensuring that the central height of the supporting pipe fittings of 1040mm remains unchanged. The roller frame is easy and efficient to open and close.

[0016] The servo cross carriage 4 is used to realize welding horizontal swing and vertical movement in the welding process, and can also realize automatic control of arc length. Among th...

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. ...
