High-precision five-axle argon arc welding machine

Abstract

The invention relates to the technical field of argon arc welding machines, in particular to a high-precision five-axle argon arc welding machine. Through arrangement of three linear modules perpendicular to each other and an A-axle rotating module, a TIG welding gun of the argon arc welding machine can finish complex motions of three-dimensional space; and workpieces are rotated through a R-axlemodule to form five-axle linkage to realize complex welding way welding. In addition, through skillful arrangement of such structures as a servo motor, a speed reducer and a precise ball screw, the high-precision control of five-axle motions can be realized; a wire filling head is not arranged on a plane of the TIG welding gun and a welding way; and through rotation of an A axle of the TIG weldinggun, the difficulty of no position interference in welding of an arc welding way with a radius smaller than 7 mm is solved. Through the arrangement, the precise machining of the workpieces can be realized; and under the condition of workpiece materials as AMS-5599, the strict requirements that the inner and outer welding line heights of the workpieces with the wall thicknesses of 1 mm are not higher than 0.25 mm and the inner and outer welding line heights of the workpieces with the wall thicknesses of 1.2 mm are not higher than 0.29 mm are met during single-surface welding and double-surfacemolding.

Description

technical field [0001] The application relates to the technical field of argon arc welding machines, in particular to a high-precision five-axis argon arc welding machine. Background technique [0002] LEAP1A Ref 2 assemblies, LEAP1A Ref 3-1 and LEAP1A Ref 3-2 assemblies, LEAP1A Ref 4-1 and LEAP1A Ref 4-2 assemblies, LEAP1B REF4-1 and LEAP1B REF4-2 assemblies are essential assemblies for use in aerospace, Made of AMS-5599 material, there are many difficulties in the welding and assembly of the above workpiece, mainly as follows: [0003] 1. The welding accuracy is extremely high, mainly reflected in the high requirements on the strength and toughness of the finished product and the height of the weld seam. Therefore, the workpiece must be welded with filler wire. In the case of using a welding wire with a diameter of 0.89mm, we require the above-mentioned wall thickness to be The weld seam height of the 1mm workpiece is not higher than 0.25mm, and the weld seam height of th...

AI Technical Summary

Problems solved by technology

[0004] 2. There is an arc with a radius of less than 7mm in the above-mentioned Ref 3 components, which puts forward extremely high requirements for the control of the weld bead of the welding torch;

[0005] 3. The defect of arc starting and closing of components must be less than 4mm;

[0006] 4. The back molding requirements of tooling are high

[0007] Based on the above-mentioned difficulties, there is no welding equipment that can overcome the above-mentioned difficulties in the prior art. Therefore, the current situation is that the above-mentioned components are mainly welded manually, but there are many defects in the manual method, such as: low efficiency , high scrap rate, high labor cost and extremely high requirements for workers' skill proficiency
