Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of rod-shaped optical product detection. Background Art
[0002] Rod mirrors, also known as cylindrical mirrors, are mainly used to change the design requirements of the image size. For example, a point spot is converted into a line spot, or the height of the image is changed without changing the image width. It has a wide range of uses in linear detector lighting, barcode scanning, holographic lighting, optical information processing and laser emission.
[0003] The rod mirror has a large thickness and a small diameter, resulting in a small diameter thickness. For a vertical interferometer, it is difficult for inspectors to stand the rod mirror on the operating table when detecting the surface shape. Due to the small diameter thickness of the rod mirror, the center of gravity is unstable during the detection process and there is a risk of falling. Direct contact with the operating table can easily cause scratches and affect the finish. For a horizontal interferometer, the inspection fixture or clamping table can easily generate stress on the edge of the rod mirror, resulting in inaccurate local aperture measurement values. Moreover, the rod mirrors can only be inspected one by one each time, which is time-consuming and labor-intensive and is not conducive to large-scale inspection. Utility Model Content
[0004] In order to solve the technical problem in the prior art that a rod mirror is difficult to fix on an operating table and clamping will affect the local aperture measurement value, the utility model provides a matrix rod mirror fixing device.
[0005] like Figure 1 As shown, a matrix rod mirror fixing device includes a fixing body 1, which is an integrated structure, and a plurality of positioning holes 2 distributed in a matrix and extending downward are opened on its surface, each of the positioning holes 2 is perpendicular to the lower surface of the fixing body 1, and is used to fix the rod mirror, and a protective flannel cloth 3 is fixed to the bottom of each positioning hole 2.
[0006] Technical effect:
[0007] 1. Separate the rod mirror from the operating table by fixing the main body, reduce the hard damage between the rod mirror and the operating table, and ensure the smoothness;
[0008] 2. The positioning hole is accurately centered, and the rod mirror is completely vertical after being placed in it, which makes it easier to find the image and solves the technical problem of unstable center of gravity and risk of falling during the detection process;
[0009] 3. Compared with the horizontal interferometer, the utility model has no clamping force and does not generate stress, making the aperture measurement value more accurate;
[0010] 4. Easy to operate, the matrix positioning hole design can measure multiple rod mirrors at one time, suitable for large-scale inspection;
[0011] 5. The protective flannel cloth fixed at the bottom of each positioning hole protects the rod mirror and increases the vibration isolation performance. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 It is a schematic diagram of the overall structure of the utility model.

[0014] The technical solutions in the embodiments will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. All other embodiments obtained by ordinary technicians in this field without creative work using the embodiments in the utility model are within the scope of protection of the utility model.
[0015] The utility model replaces the existing single measurement mode with a matrix type multiple measurement mode. When measuring, the rod mirror is placed in the positioning hole 2 with the protective flannel 3, the fixed body 1 is placed on the operating table, the lens is installed and the parameters are adjusted to start the measurement, and it is only necessary to move the fixed body 1 to drive the rod mirror until all the rod mirrors are measured.
