Tool for assembling instrument board sub-assembly

The present invention discloses a tool for assembling an instrument board sub-assembly. The tool comprises a first support frame, a second support frame, a first rotating assembly, a second rotating assembly, a synchronous stabilizer bar and a positioning part, wherein the first support frame and the second support frame are oppositely arranged; the first rotating assembly is rotatably arranged on the first support frame; the second rotating assembly is rotatably arranged on the second support frame; the synchronous stabilizer bar is connected between the first rotating assembly and the second rotating assembly; and the positioning part is arranged on one of the first rotating assembly and the second rotating assembly so as to limit a rotating angle of the corresponding rotating assembly. According to the tool for assembling the instrument board sub-assembly, disclosed by the present invention, the rotatable first rotating assembly and second rotating assembly are arranged on the first support frame and the second support frame and the positioning part is utilized to implement limitation to the rotating angle. Therefore, the instrument board sub-assembly is effectively prevented from having the defects of scratches, deformation and the like in the assembling process, so that quality of the product is improved, the assembling efficiency is improved and the production cost is reduced.
