Description

Technical Field

[0001] The invention relates to the technical field of magnetic shielding component welding, and in particular to a magnetic shielding component welding tool. Background Art

[0002] The magnetic shielding assembly refers to a housing made of a soft magnetic material with a large magnetic permeability (such as Permalloy). The optical fiber ring is placed in the housing. Since the housing magnetic permeability μ is much larger than the air magnetic permeability μ, most of the magnetic flux lines pass through the wall of the housing, while there are few magnetic flux lines in the cavity inside the housing, thus achieving the purpose of magnetic shielding. The development of formulas and models for most magnetic shielding bodies is based on the geometric shape of a circle or an infinitely long cylinder. In practical applications, according to the shape and structure of the optical fiber ring, the magnetic shielding cover is designed as a circular magnetic shielding body. Usually, the base and the upper cover are matched, and then the gaps and connection points of the matching parts are welded using an advanced laser welding system, so that the assembled magnetic shielding body can obtain the optimal magnetic shielding effect. The magnetic non-reciprocity error generated by the optical fiber ring in the magnetic field is one of the main factors restricting the application of high-precision interferometric optical fiber gyroscopes. The error is related to the magnetic field strength. Laser welding can reduce the influence of the connection gap of the magnetic shielding material on the shielding effectiveness, improve the accuracy of the magnetic shielding assembly in the magnetic field and temperature environment, and meet the performance requirements of high-precision optical fiber gyroscopes. There are many types of magnetic shielding components, and the diameters of various magnetic shielding components are also different. There are also differences in welding gaps. The welding tooling used when welding the connecting gaps of magnetic shielding materials also needs to be customized. Currently, each time a new type of magnetic shielding component is produced, the corresponding and matching welding tooling must be processed and manufactured according to the size of the magnetic shielding component, and the economic cost is extremely high. Therefore, the present invention proposes a magnetic shielding component welding tooling to solve the problems existing in the prior art. Summary of the invention
