Embodiment Construction

[0067] The present invention will be described in detail below in conjunction with the drawings:

[0068] Such as figure 1 , figure 2 with Picture 9 Shown:

[0069] A multifunctional iris device, which is characterized by comprising a housing assembly 1, an aperture assembly 2 and a lens fixing assembly 3;

[0070] The housing component 1 includes an upper shell 1-1, a base 1-2, a lower cover 1-3 and hexagon socket bolts 1-4;

[0071] Such as image 3 , Figure 4 with Figure 5 As shown, the upper shell 1-1 is a slotted cylinder and rectangular parallelepiped combined structure, including an upper shell substrate 1-1-1; the upper shell substrate 1-1-1 has an upper shell at the center of the cylindrical shape. Through hole 1-1-2, there are two upper shell mounting through holes 1-1-3 near the long end of the cuboid, and two upper shell fixing threaded holes 1-1-4 at the center of the long end of the cuboid, the center of symmetry The front end of the position is provided with a thro...

Abstract

The invention discloses a multifunctional iris diaphragm device which comprises a shell assembly (1), a diaphragm assembly (2) and a lens fixing assembly (3). The device can be used as a diaphragm andcan also be used as a device of a lens fixing frame; when the device is used as a diaphragm, scales (2-4-3) are observed, a rotary knob (2-4) is rotated to drive a worm (2-3), a shifting piece disc (2-1) is driven to rotate through meshing, and thus the size of an unthreaded hole between light shielding sliding pieces (2-2) is controlled through a shifting piece disc guide rail groove (2-1-2). When the device is used as the lens fixing frame, the unthreaded hole is adjusted to the maximum, the adjusting knob (3-1) slides along the 1 / 3 annular groove (1-3-4) to drive the drive plate (3-2) to rotate, and the bent guide groove (3-2-3) of the drive plate (3-2) controls the lens fixing device (3-3) to be folded inwards or unfolded outwards. The whole structure is simple, the operation is convenient and the reliability is good.

Description

Technical field [0001] The invention relates to the technical field of precision instruments and machinery, in particular to a multifunctional iris device. Background technique [0002] In the exposure system, different imaging needs to correspond to different apertures to control the throughput of the beam. The previous design was to process multiple diaphragms with small holes of different diameters, and it was extremely inconvenient to disassemble and assemble the diaphragms with different apertures when performing corresponding experiments. In order to solve the above problems, it is necessary to design a mechanical structure that can precisely control the change of the diaphragm size. [0003] The Chinese invention of Patent Publication No. 102213891A discloses a structure that realizes the overlapping of the blades through the combination of multiple sets of blade structures, thereby changing the size of the aperture. This structure is characterized by a sophisticated struct...
