Abstract

The invention discloses an optical mirror magnetic suspension supporting device. The optical mirror magnetic suspension supporting device comprises an axial electromagnetic guiding device, a radial electromagnetic guiding device and an optical mirror fixing device. In the axial electromagnetic guiding device, electromagnets I are uniformly mounted on a bottom plate at the lower end of the opticalmirror fixing device, and permanent magnets I are uniformly mounted at the bottom of the optical mirror fixing device. In the radial electromagnetic guiding device, electromagnets II are uniformly mounted on the inner sides of vertical mounting plates on the edge of an electromagnet mounting frame through screws, and permanent magnets II are uniformly mounted on the outer wall of the optical mirror fixing device through set screws. The side face of an optical mirror to be processed is limited and fixed to the optical mirror fixing device through locking screws. The optical mirror magnetic suspension supporting device can implement height supporting and posture adjustment on the mirror in the optical primary mirror processing process. The supporting device is effectively protected against damage caused by processing impact or vibration through flexible supporting. Meanwhile, the problems of friction, leakage, stagnation and the like occurring through an original supporting method are solved. The optical mirror magnetic suspension supporting device is easy to maintain and convenient to operate.

Description

technical field

[0001] The invention relates to a support device for an optical mirror, in particular to a magnetic levitation support device for an optical mirror, especially suitable for processing and supporting a large optical mirror, and belongs to the technical field of optical mirror processing equipment. Background technique

[0002] With the rapid development of optical technology, curved optical parts as the core components are widely used in military reconnaissance, aerospace and many civilian fields, such as projectors and camera lenses, viewfinders, telescopes and other fields, and modern optical systems It is rapidly developing in the direction of large diameter, high precision, high resolution and high power, and the demand for large optical mirrors is increasing, so there is a higher standard for the processing accuracy of optical mirrors. However, in the processing of large aperture and optical mirror, the difficulty of supporting the primary mirror also inc...
