AI Technical Summary

Technical Problem

In existing technologies, it is not convenient to adjust the height of optical lenses of different sizes during optical lens inspection. This causes the position of the optical lens in the vertical direction to change when using a conversion sleeve, which leads to problems such as difficulty in improving the accuracy of inspection of optical lenses of different sizes and the need for position adjustment of lenses of different sizes during inspection.

Method used

An optical lens clamping fixture was designed, which includes a base plate and a clamping plate. The clamping plate is provided with clamping holes and through holes. The height position of the optical lens can be adjusted by fixing rod and adjusting sleeve, which solves the problem of the inconvenience of adjusting the height position of optical lenses of different sizes in the prior art.

Benefits of technology

It enables height adjustment of optical lenses of different sizes, improving the accuracy and convenience of testing.

Claims

1. An optical lens clamping tool, characterized in that, The device includes a base plate and a clamping plate. The clamping plate has a clamping hole for the lower end of the optical lens to be inserted into. The clamping plate also has a clamping rod that is detachably connected to it. The clamping rod can be horizontally inserted into or removed from the clamping hole to clamp the optical lens in the clamping hole. The clamping plate also has a pair of through holes through which a fixing rod is inserted. The lower end of the fixing rod is vertically fixed to the base plate. The upper end of the fixing rod is threaded with an adjusting sleeve that can abut against the clamping plate. A support spring is also arranged around the fixing rod between the clamping plate and the base plate.

2. The optical lens clamping tool of claim 1, wherein, The through hole includes a sliding section and a through section located below the sliding section. The inner diameter of the sliding section is larger than that of the through section, and the inner diameter of the through section is larger than that of the fixed rod. The lower outer wall of the adjusting sleeve is in sliding contact with the sliding section.

3. The optical lens clamping tool of claim 2, wherein, The upper outer wall of the fixed rod is provided with an external thread section, and the inner wall of the adjusting sleeve is provided with an internal thread section that is threaded to the external thread section.

4. The optical lens clamping tool of claim 2, wherein, The through hole also includes an inlet section located below the through section and with an inner diameter larger than the through section, with the upper end of the support spring abutting into the inlet section.

5. The optical lens clamping tool of claim 1, wherein, The upper outer wall of the adjusting sleeve is provided with recessed texture.

6. The optical lens clamping tool of any one of claims 1-5, wherein, The inner diameter of one end of the adjusting sleeve is smaller than that of the other end, and the end with the larger inner diameter is fitted onto the end of the fixed rod.

7. The optical lens clamping tool of claim 1, wherein, The card hole is equipped with an annular support platform, and the card plate is also equipped with a tightening screw hole that runs horizontally through the space above the annular support platform.
