A rotatable large-aperture optical element fixture

Abstract

The invention discloses a rotatable large-caliber optical element clamp, and relates to a clamp for a testing platform. The rotatable large-caliber optical element clamp is provided with X-axial and Y-axial feeding parts and a gradient adjustable mechanism. The X-axial feeding part is provided with a clamp base, a hand wheel, a lead screw, a rolling linear guide rail and a slider. The Y-axial feeding part is provided with a Y-axial feeding base, a Y-axial feeding block and a micrometer. The gradient adjustable mechanism is provided with a rotating body, a base, a spring, a wedge block, a support frame, a clamp top layer, a clamping element, a two-way worm and a small hand wheel. According to the rotatable large-caliber optical element clamp provided by the invention, feed can be operated along the X-axis and the Y-axis, and the rotatable large-caliber optical element clamp can be rotated around the Y-axis for a certain angle, and the flexibility of the gradient adjustable mechanism is great. The rotatable large-caliber optical element clamp is adopted for positioning and clamping an optical element to be tested. The X-directional feed is driven through selection of a two-way hand wheel. The Y-axial feed is pushed by the micrometer with 1 micron precision. The gradient adjustable mechanism is provided with a wedge groove to be matched with the wedge block, and is supplemented by screws for locking. The degree of stability is high, and a screw hole is crescent. The lead screw is driven to rotate by the hand wheel, so that the Y-axial feeding base is driven along the rolling linear guide rail to realize the X-axial feed.

Description

technical field [0001] The invention relates to a fixture for a detection platform, in particular to a large rotatable fixture with horizontal (X-axis) and longitudinal (Y-axis) feed and measuring plane tilting functions for positioning and clamping components. Aperture Optics Fixture. Background technique [0002] As one of the precision components, optical components are widely used in optical systems, and the optical components are developing in the direction of large-scale high-precision and small-scale high-precision. Aspherical optical elements have been widely used in TV camera tubes, zoom lenses, satellite infrared telescopes and other equipment because of their advantages of obtaining good imaging quality, correcting various aberrations, and improving imaging quality. Aspheric surfaces are widely used in high-tech fields such as aerospace, national defense, astronomy, medical treatment, and optoelectronics. Among them, large-diameter optical aspheric elements (abov...
