[0002] After production, acrylic lenses need to be tested for quality. The tests include pressure resistance and abrasion resistance. The abrasion resistance test involves grinding the surface of the acrylic lens to cause damage, thereby testing the degree of damage under a certain pressure value.

[0003] Chinese Patent Publication No. CN222070385U discloses a device for testing the surface abrasion resistance of acrylic lenses. The device includes a frame with four lens clamping components evenly mounted on its top. A lens abrasion resistance detector is mounted at the center of the top of the frame. Each lens clamping component includes a mounting base with three equally spaced grooves. A slider slides within these grooves, and a pressing block is fixed to each slider. An inclined plate is fixed to the outer end of the slider. A pressing mechanism for pressing the inclined plate is mounted on the outer wall of the lens clamping component. The pressing mechanism includes a rotating ring rotatably mounted on the top of the frame. A fixing strip is fixed to the inner wall of the rotating ring at a position corresponding to the inclined plate. A pressure roller is fixed within the fixing strip and is positioned close to the inclined surface of the inclined plate. This invention, through the above structural design, can simultaneously place and press multiple acrylic lenses, then perform abrasion resistance testing on each lens individually, resulting in higher efficiency.

[0004] However, traditional wear resistance testing devices do not have pressure adjustment function, so they cannot adjust different pressure values ​​for different pressure requirements and cannot adapt to different testing needs. Moreover, the efficiency of a single test is slow, which is not conducive to batch sampling inspection. Utility Model Content

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An acrylic lens surface abrasion resistance testing device includes a base, a column fixedly installed at the rear of the base, a fixed beam fixedly installed at the upper front of the column, and a sliding groove formed on the front surface of the column, through which the column is slidably connected to the sliding beam.

[0022] 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.

[0023] Example 1

[0024] Combination Figures 1-6 An acrylic lens surface abrasion resistance testing device includes a base 1, a column 2 fixedly installed at the rear of the base 1, a fixed beam 3 fixedly installed at the upper front of the column 2, and a sliding groove opened on the front surface of the column 2. The column 2 is slidably connected to the sliding beam 4 through the sliding groove. A cylinder 5 is fixedly installed on the upper part of the fixed beam 3, and the output shaft of the cylinder 5 passes through the fixed beam 3 and is fixedly connected to the sliding beam 4.

[0025] See Figures 1-4Furthermore, it is found that a fixed plate 6 is fixedly connected to one end of the sliding beam 4 by two L-shaped support rods, and a motor 7 is fixedly installed on the upper part of the sliding beam 4. The output shaft of the motor 7 passes through the sliding beam 4 and is inserted into the interior of the fixed plate 6. Several pressure regulating structures 10 are arranged in a ring at the edge of the fixed plate 6. The pressure regulating structures 10 are used to connect the grinding disc 9. A carrier 8 is fixedly installed on the upper part of the base 1, vertically aligned with the lower part of the grinding disc 9. An active gear ring 11 is rotatably connected inside the fixed plate 6, and the center point of the active gear ring 11 is fixedly connected to the output shaft of the motor 7.

[0026] Specifically, the sliding beam 4 can slide using the power of the cylinder 5 via the sliding groove. During the sliding process, it drives the fixed plate 6 to move vertically, so that the grinding disc 9 can contact the acrylic lens set on the carrier 8. The carrier 8 can be a pneumatic suction cup or a mechanical carrier.

[0027] Example 2

[0028] See Figure 2 Furthermore, based on Embodiment 1, the pressure regulating structure 10 includes a fixed sleeve 12, which penetrates the fixed disc 6. A flange is rotatably connected to the outside of the fixed sleeve 12, and the flange is fixedly connected to the fixed disc 6. A connecting post 14 penetrates the bottom of the inner side of the fixed sleeve 12. A limiting head 15 is fixedly connected to the top of the connecting post 14 inside the fixed sleeve 12. A spring 16 is placed above the limiting head 15. A bolt 18 is threadedly connected to the center of the top of the fixed sleeve 12. A pusher 17 is rotatably connected to the bottom of the bolt 18. The pusher 17 is located at the top of the spring 16. The grinding disc 9 is fixed to the connecting post 14 through an opening at its bottom by screws. Two limiting protrusions are symmetrically arranged on the outside of the connecting post 14 and the pusher 17. The limiting protrusions slide and match the inner wall of the fixed sleeve 12. A driven gear ring 13 is fixedly installed on the outside of the fixed sleeve 12, and the driven gear ring 13 meshes with the driving gear ring 11.

[0029] Specifically, rotating bolt 18 causes the height of push head 17 to change. During this change, spring 16 is either released or compressed, thus reducing the pressure of spring 16 on limit head 15. Then, the acrylic lens is placed on the upper part of carrier 8, and cylinder 5 is started. The output shaft of cylinder 5 pushes sliding beam 4 vertically downward. During the downward movement, pressure regulating structure 10 moves downward, which in turn moves grinding disc 9 downward. When grinding disc 9 contacts the surface of acrylic lens, motor 7 is started. The output shaft of motor 7 drives active gear ring 11 to rotate. Active gear ring 11 drives each driven gear ring 13 to rotate. Each driven gear ring 13 drives fixed sleeve 12 to rotate. Fixed sleeve 12 drives grinding disc 9 to rotate, polishing the acrylic lens. After polishing for a certain period of time, the work is stopped, and the wear condition of the acrylic lens is observed to determine the wear resistance of the acrylic lens.

[0030] It should be noted that this utility model is a wear resistance testing device for acrylic lens surfaces. In use, the acrylic lens to be tested is installed on the upper part of the carrier 8. Then, the cylinder 5 is started, and the cylinder 5 pushes the sliding beam 4 to move vertically downward, so that the grinding disc 9 contacts the acrylic lens. Then, each bolt 18 is rotated as needed, and the bolt 18 pushes the push head 17 to move, thereby driving the spring 16 to compress, increasing the pressure of the spring 16 on the limit head 15, thereby increasing the pressure of the grinding disc 9 on the acrylic lens. Finally, the motor 7 is started, and the output shaft of the motor 7 drives the active gear ring 11 to rotate. The active gear ring 11 drives the fixed sleeve 12 to rotate through the driven gear ring 13. The fixed sleeve 12 drives the grinding disc 9 to rotate, and the grinding disc 9 polishes the acrylic lens. After the working movement time, the work is stopped, and the wear condition of the acrylic lens is observed to determine the wear resistance of the acrylic lens.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
