Description

Technical Field

[0001] The utility model relates to a telescope lens turning processing fixture, in particular to a telescope lens turning processing fixture, belonging to the technical field of fixtures. Background Art

[0002] A telescope is an optical instrument that uses lenses, mirrors, and other optical devices to observe distant objects. It uses the refraction of light through a lens or the reflection of light by a concave mirror to converge into an image through a small aperture. This image is then viewed through a magnifying eyepiece. It's also called a "telescope." The front end of the telescope is equipped with a lens, a type of lens found in video cameras and camcorders. It's a telephoto lens, typically with a focal length of 800-1200mm.

[0004] In the above scheme, although the position of the clamping ring can be adjusted by the threaded rod to achieve the clamping of lens barrels of different sizes to facilitate subsequent turning processing, the distance between the two lens barrels of different models of telescopes is also different. However, the spacing between the cylindrical positioning pins and the diamond limit pins in the device is fixed, and the position of the clamping mechanism such as the clamping ring is also fixed, and it cannot be adapted to different or more models of telescopes, thereby reducing the applicability of the telescope lens turning fixture.

[0029] See also Figure 4 A telescopic rod 7 is provided between the pressure strip 601 and the clamp seat 1. The telescopic rod 7 includes a thick rod and a thin rod that are slidably connected to each other. The bottom end of the thick rod is fixedly connected to the upper part of the clamp seat 1, and the top end of the thin rod is fixedly connected to the bottom of the pressure strip 601. The telescopic rod 7 is located on one side of the first threaded rod 602, and the first threaded rod 602 and the telescopic rod 7 are arranged parallel to each other.

[0030] The telescopic rod 7 mainly serves to stabilize the pressure strip 601 .
