Description

Auxiliary tool for welding air duct Technical Field The invention relates to the technical field of workpiece positioning and fixing devices, in particular to an auxiliary welding tool for an air duct. Background In the cyclone, an inclined flange 102 is welded to the top of the air duct 101 of the cyclone 100 so as to be connected to an inclined partition plate of the cyclone by the flange 102, as shown in fig. 1. In the past, adopt manual welding, accessible marks the welding position at the air duct and confirms ring flange inclination, when adopting welding arm to weld in order to alleviate intensity of labour, need fix a position the ring flange through the frock, do not have at present to be applicable to air duct welded frock. Disclosure of Invention Aiming at the defects in the prior art, the invention provides an auxiliary welding tool for an air duct, and aims to realize rapid positioning of an inclined flange plate on the air duct so as to improve automatic welding efficiency. The auxiliary welding fixture for the air duct comprises a base, wherein the top of the base is hinged with a bracket through a horizontal hinge shaft, a rotation driving mechanism is arranged on the base and used for driving the bracket to rotate, a plurality of air duct positioning grooves which are arranged in parallel are arranged on the bracket, the axis of each air duct positioning groove is orthogonal to the horizontal hinge shaft, one end of each air duct positioning groove is provided with a flange positioning frame, the surface of the end part of each flange positioning frame, which is away from the corresponding air duct positioning groove, is a flange positioning surface, and the flange positioning surface is inclined to the axis of each air duct positioning groove. Further, the lifting frame is arranged on the bracket, the lifting driving mechanism is used for driving the lifting frame to lift, the top surface of the lifting frame is not higher than the bottom of the air duct positioning groove when the lifting frame descends, and the top surface of the lifting frame is higher than the notch of the air duct positioning groove when the lifting frame ascends. The welded air duct can leave the auxiliary welding tool of the air duct through rolling by lifting the lifting frame, so that the blanking efficiency is improved.
