The invention discloses a vacuum adsorption fixture and an adsorption method for clamping thin-walled spherical shell micro-components, and relates to the technical field of thin-walled spherical shell micro-component clamping. Aiming at the problems of difficult operation and complex control parts in the existing clamping method in the process of processing the thin-walled spherical micro-components, which cause large deformation of the spherical shell and low repeat positioning accuracy, etc. . Technical points: The vacuum suction head is sealed and detachable connected with the adsorption end of the vacuum adsorption fixture main body. The vacuum chamber on the vacuum adsorption fixture body along its axial direction becomes smaller along the connection end to the adsorption end; The main body of the adsorption fixture is provided with an auxiliary gas source interface communicating with the vacuum chamber. When vacuum adsorption fixtures are used to adsorb small components such as thin-walled spherical shells, the specific structural shape of the suction head and the size of the vacuum negative pressure are calculated and checked. The clamping head of the present invention is suitable for flexibly adjusting the degree of vacuum according to the deformation of the thin-walled spherical shell, that is, adjusting the suction force of the clamping head, reducing clamping deformation, and ensuring machining accuracy.

technical field [0001] The invention relates to a vacuum adsorption fixture and an adsorption method for clamping thin-walled spherical shell micro-components, and relates to the technical field of thin-walled spherical-shell microcomponent clamping. [0002] technical background [0003] With the continuous development and progress of science and technology, various thin-walled spherical shell micro-components with weak stiffness are widely used in biomedical, electronic information, aerospace, national defense and military fields, and the surface shape is required to reach sub-micron shape accuracy, Nanoscale surface roughness and minimal subsurface damage. Appropriate clamping methods are needed to reduce clamping deformation and ensure that the workpiece is not damaged, and ultra-precision micro-milling can achieve high-precision machining of full-surface cross-scale feature structures. [0004] For example, the thin-walled spherical shell micro-components used in energy...
