Description

Technical Field

[0001] The utility model relates to the technical field of welding jigs, in particular to a welding device for furnace plate stiffeners. Background Art

[0002] The stiffeners of the furnace plate are design components that improve the structural strength and stability of the furnace plate. They are usually strip-shaped raised structures, distributed on the surface of the furnace plate in a criss-cross or specific pattern. Their main function is that when the furnace plate bears high temperature, pressure or mechanical load, the stiffeners can disperse stress and avoid local stress concentration leading to deformation and cracking of the furnace plate;

[0003] Currently, when manually welding the stiffeners of the furnace plate, due to the lack of a multi-directionally adjustable positioning mechanism, it is difficult to accurately align the welding positions of the stiffeners of different models of furnace plates. Repeated manual adjustment is likely to cause welding deviation, affecting the stress dispersion effect of the furnace plate, and may even cause deformation and cracking due to local stress concentration. Moreover, traditional devices need to replace special jigs for different furnace plate models, which is cumbersome and time-consuming. Taking a medium-sized or small-sized welding workshop as an example, the single jig replacement usually takes 20 - 30 minutes, and frequent replacement seriously affects the efficiency of the assembly line operation. Especially in the scenario of multi-variety and small-batch production, the problem of insufficient equipment utilization is particularly prominent. Summary of the Utility Model

A T-shaped shaft 17 is fixedly installed at the lower end of the adjustment bolt 16. The T-shaped shaft 17 is rotatably installed in the counterbore 15, and the adjustment bolt 16 is also threadedly connected to the screw holes in the height adjustment block 8 and the fixed shaft 9. When the lower end of the adjustment bolt 16 rotates in the base 6 through the T-shaped shaft 17, it can rotate synchronously in the screw holes in the height adjustment block 8 and the fixed shaft 9, so as to realize the adjustment of the use height of the fixture 14 through the height adjustment block 8, the extension beam 11 and the carrier 13.

[0025] As Figures 2 - 5As shown, a fixed skirt 18 is fixedly installed on the outside of the top block 10, and a first toothed ring 19 is fixedly installed at the lower end of the top block 10. The top block 10 is arranged at the top of the fixed shaft 9, and the first toothed ring 19 is arranged along the outer contour of the fixed shaft 9 at the bottom of the top block 10, which can provide conditions for limiting the axial movement of the extension beam 11.
