Description

Technical Field

[0001] This utility model relates to the field of lens measurement technology in the optical industry, specifically a tooling for measuring the perpendicularity of a cut lens. Background Technology

[0002] Measuring the perpendicularity of cut lenses has always been difficult, especially the perpendicularity between the cut surface and the platform. Current technology usually uses coordinate measuring machines to measure lenses, but this method is very time-consuming and also carries the risk of damaging the lens, so it needs to be solved urgently. Summary of the Invention

[0003] Purpose of the utility model: The purpose of this utility model is to solve the above-mentioned technical problems and provide a tooling for measuring the perpendicularity of a cut lens.

[0004] Technical solution: The present invention provides a cutting lens measuring perpendicularity fixture, comprising a bracket, a lens support suction seat on the bracket, a suction port and an air passage on the lens support suction seat, the suction port and the air passage being connected; a rubber ring is provided on the suction port.

[0005] Furthermore, the lens support is fixed to the bracket by screws.

[0006] Furthermore, the lens support suction base and the bottom of the bracket have reserved space.

[0007] Furthermore, the bracket is L-shaped.

[0008] Furthermore, the suction port has an air-proof area inside.

[0009] Furthermore, the suction port is provided with at least two levels of grooves from the outside to the inside to accommodate rubber rings of different sizes.

[0010] Beneficial effects: This utility model has the following beneficial effects:

[0011] 1. This utility model enables rapid measurement of cut lenses by vacuum suction of the lens and then measuring the angle between the lens cutting surface and the fixture platform using a tool microscope.

[0012] 2. Using a rubber ring allows the vacuum suction to better adhere to the lens, preventing air leakage;

[0013] 3. It can reduce the risk of damaging the lens during the measurement process. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figure 1 As shown, this utility model discloses a fixture for measuring the perpendicularity of a cut lens, comprising an L-shaped support 1. A lens support suction base 2 is mounted on the support 1, and the lens support suction base 2 has a suction port 21 and an air passage 22, which are connected. A rubber ring 4 is mounted on the suction port 21. Specifically, the lens support suction base 2 is fixed to the support 1 by screws 3. A reserved space 11 is provided between the lens support suction base 2 and the bottom of the support 1 to accommodate lenses of different diameters. An anti-cavity area 212 is provided inside the suction port 21 to provide anti-cavity for convex lenses. The suction port 21 has at least two levels of grooves 211 from the outside in to accommodate rubber rings 4 of different sizes.

[0018] like Figure 1 As shown, this utility model is used as follows:

[0019] 1. First, attach the rubber ring 4 to the lens support suction base 2, and ensure the flatness of the rubber ring 2;

[0020] 2. Use screw 3 to connect the lens support bracket 2 to the bracket 1;

[0021] 3. Connect the vacuum connector to the air channel 22 on the lens support suction base 2;

[0022] 4. Place the assembled fixture under a tooling microscope and adjust the focus of the tooling microscope.

[0023] 5. After focusing, place the sample 5 to be tested on it to test whether it is accurate. If it is accurate, it can be used in batches. If it is inaccurate, replace it with a different wire diameter or set a rubber ring 4 with a different diameter or wire diameter in a different groove 211, and then measure again until it is accurate.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
