Problems solved by technology

[0002] For the hoisting and dumping of ladle tanks, the suspension shaft is an indispensable restriction. During installation, the suspension shafts on both sides of the ladle tank have strict requirements on the installation coaxial error, and large ladles are not suitable for finishing with machining centers due to their large volume. Positioning, in the prior art, the suspension shaft and the ladle are usually cast as one, and the part of the suspension shaft located in the ladle tank is cut off in the subsequent processing. This method not only wastes a lot of material, but also needs to be processed and cut The part of the hanging shaft is labor-intensive and time-consuming

Abstract

The invention relates to a large ladle hanging shaft welding positioning device and a construction method thereof. The large ladle hanging shaft welding positioning device comprises a long positioning shaft and two positioning disks with the same size, wherein the cylindrical form error of the circumferential side of the long positioning shaft is not greater than 0.05mm; the positioning disks are coaxial with the long positioning shaft; the coaxial error of the positioning disks and the long positioning shaft is not greater than 0.03mm; the two positioning disks are relatively parallel and are detachably arranged on the long positioning shaft in a sleeving way. Compared with the prior art, the large ladle hanging shaft welding positioning device has the benefits that the operation is simple, and a ladle tank hanging shaft can be accurately positioned and packaged. Compared with the conventional method for integrating a hanging shaft and a ladle tank, the construction method has the advantages that materials are greatly saved, the working procedure is simplified, and both labor and time are saved.
