Problems solved by technology

[0004] However, in the existing copper bar single-sided double-point spot welding process, the copper bar tooling is expensive, and each model needs to replace the copper bar tooling, resulting in high tooling costs; The two welding heads on the upper electrode share a current circuit. Since the two welding heads are not synchronized during welding, when one spot welding is performed, the other welding spot is prone to shunt, which affects the quality of the welding spot.

Abstract

The invention discloses a ceiling welding tool and a ceiling welding process. The ceiling welding tool comprises two symmetrically arranged supporting platforms, a plurality of tool fixtures are arranged at intervals on each supporting platform, the tool fixtures are slidably arranged on the supporting platforms and are used for fixing upper cantilever beams while installing a ceiling. The ceiling welding tool provided by the invention has simple structure, is convenient to realize and can effectively reduce tool expense. Meanwhile, the ceiling welding tool provided by the invention can be used for carrying out double-side single-spot welding on the ceiling and can effectively improve the welding quality of the ceiling.

Description

technical field [0001] The invention relates to ceiling welding technology, in particular to a ceiling welding tool and a ceiling welding process. Background technique [0002] The roof of the urban rail vehicle body generally adopts the spot welding process, that is, the assembled roof beams and roof corrugated plates are welded together by the spot welding process to form a structurally stable roof. [0003] At present, the ceiling welding process generally adopts the single-sided double-point spot welding process of copper bars to weld the ceiling, including tooling steps and welding processes. Specifically, before welding, the curved beams of the ceiling are assembled according to the shape of the ceiling by using the copper bar tooling, and the corrugated boards of the ceiling are paved; At the same time, the copper bar located under the curved beam of the ceiling is used as the lower electrode, and the upper electrode is the double-point welding head located above the...
