Problems solved by technology

[0002] Since gas, oil, and water pipes are often bent and then butt welded in aerospace systems, this requires high centering and butt joint accuracy of the pipes after bending, and poor weld formation often occurs during the welding process. The deformation after welding is large and unsightly, and the welding efficiency is low
Existing pipe welding equipment cannot solve the above problems well

Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Such as figure 1 with figure 2 As shown, the present invention provides a thin tube six-degree-of-freedom centering butt welding device. After the thin tube workpiece 6 to be centered and butt-jointed is subjected to the action of the axial centering mechanism I and the axial centering mechanism II, the shaft The centering accuracy reaches the welding standard, and now the crank handle 32 is shaken to pull the axial butt joint mechanism to run, so that it can complete the butt joint task before the pipe welding. The structure of the device in this embodiment is consistent with that in the summary of the invention, and will not be repeated here.

[0026] The working principle of the present invention is as follows:

[0027] Such as Figure 4 with Figure 7 As shown, use the fork lock I2 to clamp one end of the thin tube workpiece 6...

Abstract

A device for welding slim tubes with six degree of freedom constrained after being centered and butted belongs to the field of welding fixtures, and comprises an axial centering mechanism I, an axial centering mechanism II, an axial butting mechanism and a machine frame; the butting and the contact of to-be-welded slim tube workpieces are completed through the axial butting mechanism after the to-be-welded slim tube workpieces are centered and positioned through the axial centering mechanism I and the axial centering mechanism II, so that the preparation operation before welding is completed. Through the invention, the welding quality of the to-be-welded slim tube workpieces can be better improved, the welding deflection is reduced, the welding seams are more attractive, meanwhile, the to-be-welded slim tube workpieces are convenient to assemble and disassemble, the operation is simple and the welding efficiency is improved.

Description

technical field [0001] The invention relates to a thin tube six-degree-of-freedom constrained centering butt welding device, which is used for centering and butt jointing of thin oil, gas and water pipes in aerospace systems before butt welding, and belongs to the technical field of welding fixtures. technical background [0002] Since gas, oil, and water pipes are often bent and then butt welded in aerospace systems, this requires high centering and butt joint accuracy of the pipes after bending, and poor weld formation often occurs during the welding process. The deformation after welding is large and unsightly, and the welding efficiency is low. Existing pipe welding equipment cannot solve the above problems well. Contents of the invention [0003] The object of the present invention is to provide a thin tube six-degree-of-freedom constrained centering butt joint method and a welding device, which can ensure the centering accuracy of the tubes between the thin tubes be...
