Problems solved by technology

The pillow-waist hoarding is an elliptical column structure, which is surrounded by two side plates with arc-shaped ends and a top plate. In the prior art, manual welding is used for connection, and the welding stability cannot be accurately controlled, especially for the top plate. Welding defects often occur at the contact position with the side plate, resulting in the failure of welding quality to meet the requirements and low work efficiency

Abstract

The invention discloses a locomotive sleeper kidney-shaped enclosure plate mechanical welding and positioning tool and a welding method implemented through the tool. The tool comprises a bottom plate fixed to a base plate of a welding device through connection bolts. The bottom plate is further provided with a supporting device, the supporting device comprises two supporting columns symmetric about the medial axis of the tool, the root portions of the supporting columns are provided with crossed auxiliary supporting plates, and positioning rings, cover plates and positioning bolts are arranged on the tops of the supporting columns. The tool has the advantages that installation is convenient, the structure is firm, a sleeper kidney-shaped enclosure plate can be effectively fixed in the welding process, welding defects caused because the base plate of the welding device rotates and accordingly a welding gun head and a weld joint deviate are avoided, and the welding effect is improved.

Description

technical field [0001] The invention relates to a positioning tool, in particular to a positioning tool applied to the mechanical welding of a waist rest panel of a railway locomotive, and a mechanical welding method applied to a waist support panel of a railway locomotive realized by using the positioning tool. Background technique [0002] The waist-rest coaming is a key and important part of the load-bearing underframe of a railway locomotive, and its welding quality directly affects the safety of the locomotive. The pillow-waist hoarding is an elliptical column structure, which is surrounded by two side plates with arc-shaped ends and a top plate. In the prior art, manual welding is used for connection, and the welding stability cannot be accurately controlled, especially for the top plate. Welding defects often occur at the contact position with the side plate, resulting in the failure of welding quality to meet the requirements and low work efficiency. Contents of th...
