Problems solved by technology

[0002] Camera lens components, astronomical optical telescope lens components, and other scientific optical instruments are widely used in civil and military fields as high-precision products, so their accuracy directly affects the quality of test data and recorded image data. Optical components It is divided into the lens part and the bracket part, and many companies manufacture the optical part and the lens part separately, as long as the processing accuracy of the product itself is guaranteed, and the actual assembly quality after the assembly is completed is ignored, so many manufacturers encounter problems in the production and assembly process. There are many assembly problems, resulting in poor product consistency and low yield

Abstract

The invention provides a collimation detector, comprising: a base, an installation post, a shaft arm, a positioning loop, an indicating gauge and an adjusting and fixing wheel. The positioning loop is provided with a screw thread corresponding to the installation post. The positioning loop is fixedly arranged on the installation post through the screw thread and through the rotation of the positioning loop, the positioning loop can move upwards and downwards along the installation post; the external surface of the positioning loop is provided with a rough surface with toothed patterns or patterns in other forms. According to the invention, a screw thread is provided on an installation post. In the invention, through the adjustment by the adjusting button and the focus adjusting instrument of the distance from the ocular lens to the products to be detected, it is possible to detect products of different focal lengths and in different sizes, therefore, increasing the utilization efficiency of the instrument.

Description

Technical field [0001] The invention relates to the field of detection equipment, in particular to a collimation detector used for lens detection. Background technique [0002] Camera lens components, astronomical optical telescope lens components, and some other scientific optical instruments are widely used in civilian and military fields as high-precision products, so their accuracy directly affects the quality of test data and recorded image data. Optical components It is divided into the lens part and the bracket part, and many companies manufacture the optical part and the lens part separately, as long as they ensure the processing accuracy of their products, and ignore the actual assembly quality after the assembly is completed, so many manufacturers encounter problems in the manufacturing and assembly process. Many assembly problems lead to problems such as poor product consistency and low yield. Therefore, in order to solve these problems encountered in actual productio...
