Auxiliary tool for welding cinder ladle trunnion seat and welding technology

Abstract

The invention provides an auxiliary tool for a welding cinder ladle trunnion seat and a welding technology. The auxiliary tool comprises a clamping device and a position changing device, and the position changing device comprises a rack and a overturning frame rotationally arranged on the rack. The clamping device is arranged on the overturning frame and comprises two clamping parts arranged on the overturning frame in a spaced mode, and each clamping part comprises middle ring foot fixing parts used for fixing middle ring feet and upper ring foot fixing parts used for fixing upper ring feet.A mounting space allowing a trunnion plate to penetrate out is further formed in the overturning frame, 360-degree all-around welding of the welding cinder ladle trunnion seat can be achieved fast andefficiently, and crane hoisting is not needed; and meanwhile, a welding robot can be applied to be linked with position changing equipment, and thus full-automatic welding of a gas shielded welding part can be achieved.

Description

technical field [0001] The invention relates to the welding field of a welding slag-wrapped trunnion seat, in particular to an auxiliary tooling and a welding process for a welding slag-wrapped trunnion seat. Background technique [0002] Such as Figure 11 As shown, the welding slag package has the advantages of high strength, strong plasticity, long service life, high repairability, and high comprehensive cost performance. The welding slag bag trunnion seat part of the welding slag bag belongs to the key part of the overall structure, plays an important function, and its structure is relatively complicated. Such as figure 1 with figure 2 As shown, the welding slag-wrapped trunnion seat 100 is made of thick plates except the trunnion 140 , wherein the butt welds of the trunnion plate 110 , the middle ring plate 120 and the upper ring plate 130 need to be ultrasonically inspected. Therefore, according to the structural characteristics of the workpiece and the welding re...

AI Technical Summary

Problems solved by technology

[0003] In the welding process of the welding slag-wrapped trunnion seat in the prior art, firstly, the part except the flaw detection seam is welded by artificial gas shielded welding. Since the welding slag-wrapped trunnion seat is heavy, it must be hoisted and turned over during the welding process. To meet the needs of welding position, bring inconvenience to welding

At the same time, because the gas shielded welding part of the traditional process is all manually welded, the welding efficiency is low, and the welding quality is unstable. It is often necessary to increase labor to repair welding defects and increase manufacturing costs. Therefore, it is urgent to solve the above problems in the production of large-scale slag ladles.
