Front end wall framework and skin assembling and welding tool

The invention relates to the technical field of welding auxiliary devices, in particular to a front end wall framework and skin assembling and welding tool which comprises a base and two vertical plates. The vertical plates are symmetrically fixed to the base, and explorator sets are fixed to the tops of the two vertical plates; clamping positions and backers which are used for supporting and positioning welding assemblies of frameworks are arranged on the top faces of explorators of the explorator sets, a plurality of pressing plates are arranged on the side faces of the explorators of the explorator sets, and a positioning arc face matched with the bottom face of an arc plate is formed on the top face of each vertical plate. Through the plurality of explorators arranged in parallel in the explorator sets, stable positioning and supporting are provided for all welding assemblies, the overall positioning requirement is met, assembly and welding operation of the frameworks can be completed conveniently through
