Automatically flipped upper beam body welding device

Abstract

The invention discloses an upper beam body welding device capable of turning over automatically. The upper beam body welding device comprises a base, the base is provided with an air cylinder support and two supporting and rotating assemblies, a rotating shaft penetrating through the supporting and rotating assemblies is connected with the two sides of a slab, and the rotating shaft is driven by a swing air cylinder; two parallel guide rails on the slab are connected with a support and a sliding block in a sliding mode, the sliding block is driven by transverse movement air cylinders, the upper end face of the support and the upper end face of the sliding block are connected with an upper supporting beam, and the lower end face of the upper supporting beam is provided with guide air cylinders for clamping upper square frames; the slab is provided with a longitudinal positioning block, a plurality of positioning blocks, clamping air cylinders for clamping the beam on the slab, a centring air cylinder for clamping upper cushion blocks and a jacking air cylinder for making the upper square frames be attached to the beam. The upper beam body welding device solves the problem of precise centring in the welding process of the upper square frames and the upper cushion blocks, the operation error generated in manual centring and welding processes is avoided, and product quality is improved; pneumatic clamping and positioning are adopted, production efficiency is improved, and the labor intensity of operators is relieved.

Description

technical field [0001] The invention belongs to a welding positioning device, in particular to an automatic turning over welding device for an upper beam body. Background technique [0002] The upper beam body is one of the important parts of the special equipment bracket, such as Figure 5 As shown, the upper beam body includes a hollow cubic column-shaped beam 31 and a plurality of upper frames 27, and the upper frames 27 are welded to the two side walls of the beam 31 correspondingly, and the upper surface of the beam 31 is also welded with an upper spacer 11 . Wherein, the welding of the upper frame 27 needs to be welded on two opposite sides of the crossbeam 31. At present, after the welding of the upper frame 27 is performed on one side, it needs to be manually turned over for secondary clamping. [0003] Welding errors in the welding process of multiple upper frames are difficult to eliminate, and the consistency of multiple upper frames after welding is poor, result...

AI Technical Summary

Problems solved by technology

Among them, the welding of the upper frame 27 needs to be welded on the two opposite sides of the beam 31. At present, after the welding of the upper frame 27 is performed on one side, it needs to be manually turned over for secondary clamping.

[0003] Welding errors in the welding process of multiple upper frames are difficult to eliminate, and the consistency of multiple upper frames after welding is poor, resulting in poor overall quality of the welded upper beam body, high labor intensity for the operator, and low work efficiency

[0004] The positioning and adjustment of the upper frame need to be done manually, and the operation is cumbersome
