Description
Technical Field
[0001] This utility model belongs to the technical field of astronomical telescope production equipment, specifically relating to an astronomical lens vibration clamp. Background Technology
[0002] After the lenses of astronomical telescopes are manufactured, they need to be placed on a vibration table for vibration testing to ensure the stability of the lens's optical axis and to remove dust. However, traditional vibration tables lack clamps to secure the astronomical lens and allow for a rigid connection between the lens and the vibration table. Therefore, this application proposes an astronomical lens vibration clamp. Utility Model Content
[0003] In order to overcome the problems in the background technology, this utility model provides an astronomical lens vibration clamp, which solves the problem that the vibration table of traditional vibrators does not have a clamp to fix the astronomical lens so that the lens is rigidly connected to the vibration table.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:
[0005] An astronomical lens vibration clamp includes a base plate, limiting blocks, support rods, pressure plates, and fastening bolts. The base plate has connecting holes. The limiting blocks are installed parallel to each other on the base plate to form several limiting groups, with each pair of adjacent limiting blocks forming a limiting group. The support rods are lead screws that are uniformly and vertically installed on the base plate. The pressure plates are movably installed on the support rods opposite to the base plate. The fastening bolts are installed on the support rods above the pressure plates.
[0006] Furthermore, the limiting block is a prism with a right-angled triangular cross-section, and the inclined surfaces of the two limiting blocks in the limiting group are arranged opposite each other.
[0007] Furthermore, the bottom of the limiting block is provided with a screw hole, one limiting block of the limiting group is fixedly installed to the base plate through a fixing hole opened on the base plate, and the other limiting block is movably installed to the base plate through a waist hole opened on the base plate.
[0008] Furthermore, the pressure plate structure is the same as the base plate.
[0009] The beneficial effects of this utility model are:
[0010] This application designs a platform that can rigidly connect the lens to the vibration table, making up for the lack of traditional vibration table lens clamps. It can be adapted to astronomical lenses of different apertures and can vibrate multiple lenses at once, improving testing efficiency. Attached Figure Description

[0017] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.
[0018] This utility model discloses an astronomical lens vibration clamp, see reference. Figure 1-4 An astronomical lens vibration fixture includes a base plate 1, limiting blocks 2, support rods 3, pressure plates 4, and fastening bolts 5. The base plate 1 has connecting holes 11 to connect it to a vibration table. The limiting blocks 2 are installed parallel to each other on the base plate 1, and every two adjacent limiting blocks 2 form a limiting group, which can horizontally limit and fix the lens. The support rods 3 are lead screws that are evenly and vertically installed on the base plate 1. The pressure plates 4 are movably installed on the support rods 3 and opposite to the base plate 1. The fastening bolts 5 are installed on the support rods 3 above the pressure plates 4, which can vertically limit and fix the astronomical lens.
[0019] See Figure 1-4 The limiting block 2 is a prism with a right-angled triangular cross section. The two limiting blocks 2 in the limiting group are arranged with their inclined surfaces facing each other. The inclined surfaces limit the lens, which facilitates the installation and fixation of lenses of different diameters and reduces wear.
[0020] See Figure 1-4 The bottom of the limiting block 2 is provided with a screw hole 21. One limiting block 2 of the limiting group is fixedly installed to the base plate 1 through the fixing hole 12 opened on the base plate 1, and the other limiting block 2 is movably installed to the base plate 1 through the waist hole 13 opened on the base plate 1. The fixing hole 12 and the waist hole 13 are provided with limiting platforms to facilitate tightening with nuts. By adjusting the distance between the two limiting blocks 2, the adaptability to lenses of different diameters can be improved.
[0021] See Figure 1-4The pressure plate 4 has the same structure as the base plate 1, which enables the installation of multiple lenses and improves testing efficiency.
[0022] Work process:
[0023] According to the aperture of the test lens, adjust the spacing between the limit blocks 2 in the upper limit group of the base plate 1 through the waist hole 13, fix the limit block 2 above the waist hole 13 with bolts and nuts, place the base plate 1 on the vibration table, install bolts in the connecting hole 11 to fix the base plate 1 to the vibration table, install the pressure plate 4 on the support rod 3 to press the end, and then fix it with fastening bolts 5. Start the vibration table to conduct targeted testing on the lens.
