Problems solved by technology

[0002] Metal pipe welding is very common in the mechanical field, especially welding metal pipes on flanges. The key to welding metal pipes on flanges lies in good coaxiality, and the welding of such products is to strengthen the connection between metal pipes and flanges. The welding strength of the blue plate is usually welded on the outer wall of the metal pipe, which further increases the difficulty of welding, and traditional manual welding is difficult to meet this requirement

Embodiment Construction

[0012] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0013] like Figure 1 to Figure 2 As shown, a metal pipe welding device, the metal pipe 1 is inserted into a base workpiece 2 provided with a central hole 21 for outer ring welding, the outer wall of the metal pipe and the inner wall of the central hole are fitted with a clearance, and the general clearance is not large. If the gap exceeds 1mm, the gap setting is too large, which will easily lead to large welding errors. If the gap is too small, the metal pipe is not easy to put into the center hole. In this example, the base workpiece is a flange, and of course it can be replaced with other shapes. The base workpiece described above is placed on a disc 3, a rotating shaft 31 is fixed vertically at the bottom of the disc, the bottom of the rotating shaft is hinged on a base plate 4, a motor 41 is arranged on the base plate, and a motor frame is ar...

Abstract

The invention discloses a metal pipe welding device. A metal pipe is inserted into a pedestal workpiece to be subject to outer ring welding, wherein a central hole is formed in the pedestal workpiece; the pedestal workpiece is arranged on a round disc; a rotating shaft is vertically fixed to the bottom of the round disc; the bottom of the rotating shaft is hinged to a bottom plate; a motor is arranged on the bottom plate and is connected with the rotating shaft through a driving belt; a positioning rod is fixed to the top part of the round disc; the outer wall of the positioning rod is connected with a positioning casing rod in a sleeving way; a through hole matched with the positioning rod is formed in the axis of the positioning casing rod; the metal pipe sleeves the outer wall of the positioning casing rod; a welding gun is arranged in the lateral direction of the round disc. The metal pipe can be quickly and accurately positioned on the workpiece to be welded, the welding speed is increased, and the welding quality is improved.

Description

technical field [0001] The invention relates to a metal pipe welding device. Background technique [0002] Metal pipe welding is very common in the mechanical field, especially welding metal pipes on flanges.
