A device for preventing welding deformation of an annular V-groove stabilizer and its application method

Abstract

The invention relates to a device for preventing welding deformation of a part, in particular to a device for preventing welding deformation of an annular V groove stabilizer and a use method of the device for preventing welding deformation of the annular V groove stabilizer. The device for preventing welding deformation of the annular V groove stabilizer comprises a supporting pressing structure, a moving jacking structure and a ventilation protection structure. The invention further provides the method for preventing welding deformation of the annular V groove stabilizer through the device. According to the device for preventing welding deformation of the annular V groove stabilizer and the use method of the device for preventing welding deformation of the annular V groove stabilizer, welding deformation of the annular V groove stabilizer is controlled through stretching jigs with adjustment mechanisms in the process of welding the annular V groove stabilizer, the technical problems that after the annular V groove stabilizer is welded, deformation is large, and correcting can not be carried out are solved, the welding accuracy of the annular V groove stabilizer is guaranteed, and the assembling and use requirements of a diffuser of an afterburner of an aero-engine are met.

Description

technical field [0001] The invention relates to a device for preventing welding deformation of parts, in particular to a device for preventing welding deformation of an annular V-groove stabilizer and an application method thereof. Background technique [0002] The annular V-groove stabilizer is a major part of the afterburner unit of the aero-engine, and its structure is as follows: figure 1 As shown, the main body material is GH536, and 12 lugs need to be welded on the annular V-groove stabilizer, which are assembled inside the afterburner diffuser, and play the role of stabilizing combustion in the afterburner in the state of engine afterburner. The original welding process of the annular V-groove stabilizer is to directly weld the lug seat on the annular V-groove stabilizer, and then correct the deformation. In fact, the correction after welding can only cause local deformation, and the shrinkage deformation that has already occurred in the welding part still exists. Ass...
