Abstract

The invention discloses a high-energy acoustic beam regulation and control device for residual stress of an annular workpiece. The high-energy acoustic beam regulation and control device comprises excitation wedge blocks, high-energy acoustic beam exciters, exciter mounting plates, fixing bolts, a triangular support frame, puller bolts, mounting bolts and a base, wherein the triangular support frame is fixed on the base through the mounting bolts, the upper part and the lower part of the triangular support frame are each provided with three threaded holes, 18 high-energy acoustic beam exciter mounting holes are evenly arranged in the circumferential direction, the puller bolts penetrate through the threaded holes to abut against the exciter mounting plates, the exciter mounting plates are each an arc-shaped plate, the 6 exciter mounting plates are arranged in the circumferential direction, the excitation wedge blocks are installed on the exciter mounting plates through the fixing bolts, the exciters are connected together through tail threads of the excitation wedge blocks, the front end of the excitation wedge block is an arc-shaped surface, and lubricating grease is smeared between the arc-shaped surface of the excitation wedge block and an annular workpiece. All the exciters and the annular workpiece can be integrally and tightly attached, energy attenuation is reduced, the conduction efficiency is improved, and efficient integral regulation and control of the residual stress of the annular workpiece are achieved.

Description

technical field [0001] The invention belongs to the technical field of residual stress control, and in particular relates to a high-energy sound beam control device for the residual stress of an annular workpiece. Background technique [0002] Ring-shaped workpieces are widely used in aerospace products. Residual stresses are likely to be generated in the manufacturing processes of sheet metal, welding, and machining. The residual stresses need to be regulated (reduced or homogenized) to ensure the stability of the final product quality. The residual stress high-energy acoustic beam control method is to use the particle wave energy of the high-energy acoustic beam to give sufficient power to the dislocation atoms of the workpiece to reduce the lattice distortion, thereby eliminating or homogenizing the residual stress. In the process of adjusting the high-energy sound beam, it is necessary to ensure that the exciter and the workpiece are closely fitted so that the energy of ...
