[0025] See also Figure 1-2 The utility model is a jig for adjusting the depth of a lens, comprising a base 1, a positioning boss 2 and a positioning column 4, wherein the base 1 and the positioning column 4 are made of wear-resistant and corrosion-resistant materials to ensure the durability and stability of the jig. The base 1 is used as a supporting base to stably support the entire jig to ensure that it does not shake during use. It can be fixedly set on a related structure such as a metal frame or a workbench. The positioning boss 2 is fixedly set on the base 1, and the outer diameter of the positioning boss 2 is consistent with the inner diameter of the tube cap 5; so as to be used to support and position the tube cap 5 structure to ensure the stability and accuracy of the tube cap 5 of the lens in the jig. The positioning column 4 is set on the positioning boss 2, and its outer diameter is smaller than the outer diameter of the lens, and its length is consistent with the depth of the lens in the tube cap 5. The sum of the length of the positioning column 4 and the height of the positioning boss 2 is equal to the target value of the depth of the lens in the tube cap 5. So as to quickly adjust the depth position of the lens in the tube cap 5 through the positioning column 4.
[0026] See also Figure 1-2 In one embodiment of the utility model, the positioning column 4 can be directly placed on the positioning boss 2, or can be fixedly connected to the positioning boss 2 to ensure its stability and avoid displacement during use. Preferably, a through hole is provided on the positioning boss 2, and a connecting portion 3 is fixedly provided at one end of the positioning column 4, and the connecting portion 3 is threadedly matched with the through hole. The connecting portion 3 is used to threadedly fix the positioning column 4 and the positioning boss 2, so that the positioning column 4 is relatively stable when in use. At the same time, the threaded connecting portion 3 makes the positioning column 4 adjustable, and the specific height of the positioning column 4 can be adjusted according to actual use needs (such as different lens models or focal length requirements) to achieve the desired depth and focal length effect.
[0027] See also Figure 1-2 In one embodiment of the utility model, a fixing block 7 is provided above the base 1, and a positioning hole is provided on the fixing block 7, and the outer diameter of the positioning hole is consistent with the outer diameter of the pipe cap 5. By providing a fixing block 7 with a positioning hole, it can cooperate with the positioning boss 2 to further limit the pipe cap 5, fully ensure the stability of the pipe cap 5, and avoid the displacement of the pipe cap 5 during the adjustment process. A positioning pin is provided on the fixing block 7, and a positioning notch is provided on the base 1. The number of the positioning pins can be four, and they are respectively provided at the corner positions of the fixing block 7. The matching accuracy of the base 1 and the fixing block 7 is ensured by the cooperation of the positioning pins and the positioning notches, thereby ensuring the accuracy of the limitation of the pipe cap 5.
[0028] See also Figure 1-2 In one embodiment of the utility model, the positioning boss 2 is provided with a positioning structure matching the shape of the G-lens lens, and the positioning structure is a positioning hole or a positioning groove. The tube cap 5 is provided with a related structure matching the positioning structure, such as a protrusion structure. By providing the tube cap 5 with a positioning structure for accurately aligning and fixing the G-lens lens, the installation accuracy of the lens is improved.
[0029] The working principle of this utility model:
[0030] 1. Material selection and preparation
[0031] First, according to actual needs, wear-resistant, corrosion-resistant and thermally stable materials are selected to manufacture various components of the fixture, such as the base 1, the positioning column 4 and the fixing block 7. These materials should be able to ensure that the fixture remains stable during long-term use and is not easily affected by environmental factors such as temperature and humidity.
[0032] 2. Assemble the base 1 and the fixing block 7
[0033] Fix the fixing block 7 to the base 1 by means of the positioning pins, and ensure that the positioning hole or groove of the boss matches the shape of the G-lens cap 5. The boss should be designed to accurately support the lens to prevent it from shaking or moving during adjustment.
[0034] 3. Install the positioning column 4
[0035] The positioning column 4 is installed on the positioning boss 2 through the connecting portion 3 to achieve accurate adjustment of the lens depth. During the installation process, the stability and accuracy of the adjustment device must be ensured to facilitate subsequent adjustment operations.
[0036] 4. Configure fixed block 7
[0037] According to the shape and size of the G-lens lens, select a suitable positioning and fixing block 7, such as a clamp, a limit plate, etc. Install the fixing block 7 on the fixture to ensure that it can firmly fix the lens. During the installation process, pay attention to adjusting the position and angle of the fixing block 7 to adapt to the fixing requirements of different lenses.
[0038] 5. Adjustment and testing
[0039] Place the G-lens lens on the boss and adjust the depth of the lens through the positioning column 4. During the adjustment process, the contact between the lens and the boss and the change in the depth of the lens can be observed. Fine-tune the positioning column 4 until the desired lens depth is reached.
[0040] After the adjustment is completed, use the test equipment to test the performance of the fixture. Check the stability of the lens in the fixture, the adjustment accuracy, and whether there is shaking or movement. If necessary, the fixture can be further optimized and adjusted based on the test results.
[0041] 6. Use and Maintenance
[0042] In actual use, the user can place the G-lens lens on the fixture to adjust the depth as needed. By adjusting the positioning column 4, the lens depth can be easily and accurately adjusted. During use, care should be taken to keep the fixture clean and dry to avoid contamination or damage to the lens. At the same time, the fixture should be inspected and maintained regularly to ensure the normal operation and service life of each component. If a component is found to be damaged or severely worn, it should be replaced or repaired in a timely manner.
[0043] Specifically, when used to adjust the depth of the lens: adjust the positioning column 4 to the target height, then combine the lens 6 of the lens with the tube cap 5 (the lens 6 of the lens can also be placed before or after the tube cap 5 is placed), then place the tube cap 5 on the base 1, and support and limit it through the positioning boss 2, then place the fixing block 7 above the tube cap 5, and apply pressure to the tube cap 5 through the fixing block 7, so that the lens can be pressed down at the same time to ensure that the lower end of the lens is in contact with the top of the positioning column 4, so that the depth adjustment process of the lens relative to the tube cap 5 is completed simply and quickly. This can effectively solve the error problem in the depth adjustment process of the G-lens lens, simplify the adjustment process, and improve the adjustment accuracy and reliability, thereby meeting the strict requirements of high-precision optical equipment for the depth control of the G-lens lens.
