Abstract

The utility model discloses a fixture for measuring the outer diameter of a lens, which comprises a slider, a guide column and a base; the slider is connected to the base through a guide column; the end of the guide column is fixedly connected with a knob through a cross screw and a baffle; The inside of the base has a trapezoidal cavity, and a copper gasket is placed in the trapezoidal cavity; a pressure sleeve is embedded at the end of the base; the guide post penetrates through the pressure sleeve in the base, and the copper gasket is screwed and connected with the slider. The utility model adopts a slope structure, can measure lenses with different outer diameters, and has a wide application range. The utility model has the advantages of simple operation, time saving and high efficiency when the lens is connected and measured. In this way, certain errors caused by the differences in testing methods of different surveyors are solved, resulting in misjudgment of quality, and accurate and stable reference information is provided for trial workers.

Description

A lens outer diameter measuring jig

technical field

The utility model relates to the technical field of optical measurement, in particular to a jig for measuring the outer diameter of a lens.

Background technique

At present, micrometers are commonly used to measure the outer diameter of optical lenses. It is difficult to fix the lens during measurement. It requires skilled practitioners, certain measurement experience and test feel. Due to personnel fluctuations or differences in measurement personnel, dimensional differences will lead to errors in measurement results. larger. Or the non-standard technique in the test process leads to excessive size differences, which seriously affects the direction of judgment of technicians.

Utility model content

The purpose of the utility model is to provide a lens outer diameter measuring jig with simple operation.

The technical scheme adopted for realizing the above-mentioned purpose is:

A jig for measuring the outer diameter of a lens, comprising a slider, a guide post and a base; the slider is connected to the base through a guide post; the end of the guide post is fixed with a knob through a Phillips screw and a stopper;

The inside of the base has a trapezoidal cavity, and a copper gasket is placed in the trapezoidal cavity; a pressure sleeve is embedded at the end of the base; the guide post penetrates through the pressure sleeve in the base, and the copper gasket is screwed and connected with the slider.

The beneficial effects of the utility model are:

1. The utility model adopts a slope structure, which can measure lenses with different outer diameters, and has a wide range of applications.

2. When the utility model connects and measures the lens, the operation is simple, the time is saved, and the efficiency is improved.

3. The outer diameter measurement jig of the utility model can minimize human measurement errors.

4. The guide column of the utility model fixes the slider and the base to fix the lens to be tested, and uses a non-gravity height gauge to measure, with small errors and more accurate measurement results.

specific implementation plan

Below in conjunction with accompanying drawing and reference numeral the utility model is described in further detail.

As shown in Figure 1-10; a jig for measuring the outer diameter of a lens, including a slider 1, a guide post 2 and a base 3;

The slider 1 is connected to the base 3 through the guide post 2;

The end of the guide post 2 is affixed with a knob 6 through a Phillips screw 8 and a blocking piece 7;

The inside of the base 3 has a trapezoidal cavity, and a copper gasket 4 is placed in the trapezoidal cavity; the end of the base 3 is embedded with a pressure sleeve 5;

The guide post 2 runs through the press sleeve 5 in the base 3 , and the copper gasket 4 is screwed and connected with the slider 1 .

The guide post 2 and the knob 6 are connected in a triangular or square clamping manner.

The end of the pressure sleeve 5 is provided with a convex edge.

The slider 1 and the base 3 are slope structures, and the measurement range is between 2-10MM.

Slider 1 and base 3 are machined from stainless steel to maintain excellent precision.

Example:

During the measurement process, the test tool uses a low-force height gauge for measurement, which can ensure the accuracy of the measurement data. During the test, place the product in a suitable position according to the drawing size of the actual lens outer diameter. Based on the plane area of the base, reset the height gauge to zero, and move 2 positions continuously to ensure that the ground is parallel and the data is consistent. Then cut the tested products in turn and place them vertically in the test area of the base. For yourself, place it at an angle of 30-150° to the reference surface, and do not touch the test reference surface, and finally measure and read the data.
