The utility model discloses a cutting torch angle fixing assisting chuck plate for a spring-assisted pressure double cutting torch floating device. Before the spring-assisted pressure floating device cuts, the cutting fixing angle of the double cutting torches is adjusted. The cutting torch angle fixing assisting chuck plate comprises an upper bevel cutting torch angle correction right-angled template, a lower bevel cutting torch angle correction right-angled template, a template fixing plate, a connecting plate and a horizontal datum plate; the upper bevel cutting torch angle correction right-angled template and the lower bevel cutting torch angle correction right-angled template are fixed on the template fixing plate through bolts; the connecting plate is fixed on the rear side surface of the template fixing plate; and the horizontal datum plate is welded on the lower end surface of the connecting plate. The angle of the two cutting torches is adjusted through the upper bevel cutting torch angle correction right-angled template and the lower bevel cutting torch angle correction right-angled template. The cutting torch angle fixing assisting chuck plate has the advantages as follows: the angle of the two cutting torches can be adjusted rapidly, the structure is simple, the operation is convenient and rapid, the positioning precision for two cutting torch angle adjustment is high, a large amount of preparation time for precutting can be saved, and the bevel cutting angle deviation meets the standard requirement.
