[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 This utility model provides a glass lens size accuracy testing device, including a testing table 1. A clamping mechanism 2 is arranged at the center of the testing table 1. Clamping seats 4 are arranged around the top of the clamping mechanism 2. A winding mechanism 5 is arranged on the left side of the bottom of the clamping mechanism 2. A second winding drum 503 is arranged on the left side of the top of the winding mechanism 5. A measuring rope 6 is fixed to the outside of the second winding drum 503. The four sets of clamping seats 4 at the top of the testing table 1 can clamp and limit the glass lens around its perimeter.

[0021] The upper surface of the testing platform 1 is provided with a first scale mark 101 horizontally, and a second scale mark 102 is provided vertically on the upper surface of the testing platform 1. A third scale mark 103 is provided on the left side of the upper surface of the testing platform 1 with the second take-up drum 503 as the axis. A second indicator block 504 is fixedly connected to the front end of the second take-up drum 503. The first scale mark 101 can be used to measure the length of the glass lens, the second scale mark 102 can be used to measure the width of the glass lens, and the circumference of the glass lens can be measured by the position indicated by the second indicator block 504 on the third scale mark 103.

[0022] The bottom of the inner side of the clamping seat 4 is provided with a fitting groove 401. The front end of the clamping seats 4 on the left and right sides of the upper surface of the testing table 1 is fixedly connected with a first indicator block 402. The left side of the clamping seats 4 at both ends of the upper surface of the testing table 1 is fixedly connected with a first indicator block 402. The fitting groove 401 can increase the stability of the glass lens fitting. The first indicator block 402 can easily indicate the position of the edge of the glass lens on the first scale mark 101 or the second scale mark 102.

[0023] The clamping mechanism 2 includes a servo motor 201 fixedly connected to the center of the bottom end inside the detection table 1. A first gear 202 is mounted on the output shaft end of the servo motor 201. A first take-up drum 203 is fixedly connected to the top of the first gear 202. Elastic pull ropes 204 are fixedly connected to the periphery of the first take-up drum 203. A through groove 3 is formed on the periphery of the inner surface of the upper surface of the detection table 1. A limit slider 301 is slidably connected inside the through groove 3. The inner side of the limit slider 301 is fixedly connected to the elastic pull rope 204. A spring 302 is fixedly connected to the inner side of the limit slider 301. The upper surface of 301 is fixedly connected to the lower surface of the clamping seat 4. When the servo motor 201 is started, it can drive the first gear plate 202 to rotate. At this time, the first gear plate 202 drives the first take-up drum 203 to rotate, which can pull the elastic pull rope 204 to wind up. The elastic pull rope 204 can drive the clamping seat 4 to move through the limit slider 301. The limit slider 301 can also squeeze the spring 302 on one side. When the servo motor 201 is turned off, due to the reaction force of the spring 302 being squeezed, the clamping seat 4 can be quickly reset through the limit slider 301.

[0024] The winding mechanism 5 includes a chain 501 externally engaged with the first toothed disc 202, and a second chain disc 502 internally engaged with the left side of the chain 501. The lower surface of the second chain disc 502 rotates inside the detection table 1, and the upper surface of the second chain disc 502 is fixedly connected to the second winding drum 503. The rotation of the first toothed disc 202 can drive the second chain disc 502 to rotate through the chain 501, and the second chain disc 502 can drive the measuring rope 6 to be wound up through the second winding drum 503.

[0025] The center position of the measuring rope 6 passes through the front end of the clamping seat 4 on the left side of the top of the test table 1. The side of the measuring rope 6 away from the second winding drum 503 is fixed to the center position of the fitting groove 401 on the left side of the clamping seat 4 on the upper surface of the test table 1. When the measuring rope 6 is wound up, the overall range of the measuring rope 6 on the right side of the clamping seat 4 becomes smaller. At the same time, the measuring rope 6 on the right side of the clamping seat 4 can cover the outside of the glass lens to complete the measurement of the circumference of the glass lens. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0026] In this embodiment, the glass lens to be measured is placed at the center of the top of the testing platform 1. The servo motor 201 inside the testing platform 1 is activated, causing the first gear 202 to rotate. The first gear 202 then drives the elastic cord 204 to wind up via the first winding drum 203. The elastic cord 204 then pulls the limiting slider 301 to move, causing the limiting slider 301 to move the four sets of clamping seats 4 at the top of the testing platform 1 close to the perimeter of the glass lens. The length and width of the glass lens can be measured by the position indicated by the first indicator block 402 on the clamping seat 4 at the first and second scale marks 101 and 102 at the top of the testing platform 1. Simultaneously, the first gear 202 drives the second chain 502 to rotate via the chain 501. The second chain 502 then drives the measuring cord 6 to wind up via the second winding drum 503 at the top. The winding of the measuring cord 6 covers the outside of the glass lens, allowing for the measurement of the glass lens's circumference.
