Description

Technical Field

[0001] This utility model relates to the field of residual stress control technology, and in particular to a magnetic residual stress control fixture. Background Technology

[0002] During the manufacturing process of ferromagnetic material components, significant residual stresses are generated due to casting, cutting, welding, and other manufacturing processes. These residual stresses not only affect the dimensional accuracy and stability of the components but may also lead to deformation and cracking during use, seriously impacting the safety and service life of the components. Therefore, effectively controlling residual stress in components has become a crucial technology for improving component quality and performance.

[0003] To address the problem of residual stress control in ferromagnetic material components, this application proposes a control fixture. This control fixture uses magnetic attraction to fix a high-power ultrasonic exciter, ensuring its stable coupling to the surface of the component being controlled. The control fixture employs a multi-degree-of-freedom mechanism, enabling the exciter to reliably couple with the surface of the workpiece even when the fixed plane is not parallel to the working plane. This flexibility allows the fixture to adapt to different working requirements and to accommodate residual stress control and in-situ control of various complex ferromagnetic material components.
