Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Example 1

[0031] To address the technical problems in the background art, the following optical glass lens forming dimension measuring device is provided:

[0032] Combination Figures 1-5 As shown, the optical glass lens forming size measuring device provided by this utility model includes:

[0033] Base 1, and fixed housing 2 fixedly installed on top of base 1;

[0034] There are four positioning plates 3. The mounting cavity 23 is opened on one side of the fixed shell 2. The top of the fixed shell 2 is opened with four sliding grooves 21 that are all connected to the interior. The sides of the four sliding grooves 21 that are close to each other are close to each other along the center of the fixed shell 2. The sliders 22 are slidably connected on the fixed shell 2 and located in the sliding grooves 21. The bottom ends of the four positioning plates 3 extend into the four sliding grooves 21 respectively, and the four positioning plates 3 are fixedly connected to the four sliders 22 respectively.

[0035] The driving mechanism 4 is mounted on the fixed housing 2 and is connected to all four sliders 22. The driving mechanism 4 is used to make the four sliders 22 slide along the four slide grooves 21 respectively.

[0036] A support frame 5 is fixedly installed on the top of the base 1 and on one side of the fixed shell 2. The other end of the support frame 5 extends to the top of the fixed shell 2. A measuring rod 51 is vertically movably inserted on the support frame 5 and above the fixed shell 2, which can contact the top of the fixed shell 2. A mounting groove 511 is provided on one side of the measuring rod 51. A scale ruler 512 is fixedly installed on the measuring rod 51 and in the mounting groove 511. A connecting plate 52 extending to the outside of the support frame 5 is fixedly installed on the top of the measuring rod 51. A groove is provided on one side of the two symmetrical sliding grooves 21 on the top of the fixed shell 2. A scale ruler 7 is fixedly installed in the groove.

[0037] When measuring the center thickness of the glass lens, the connecting plate 52 is pulled to move the measuring rod 51 upward on the support frame 5, causing the scale 512 to move upward synchronously. The glass lens is placed at the top center of the fixed shell 2. The force on the connecting plate 52 is then removed. Under the gravity of the measuring rod 51 and the connecting plate 52, the measuring rod 51 and the connecting plate 52 fall, allowing the bottom of the measuring rod 51 to contact the top of the glass lens. At this time, the driving mechanism 4 causes the four sliders 22 to slide along the four grooves 21 and move closer to each other, thereby causing the four positioning plates 3 to move closer to each other, so that the four positioning plates... All four positioning plates 3 are positioned against the outer wall of the glass lens to locate it, and the glass lens is positioned directly below the measuring rod 51, so that the measuring rod 51 contacts the center of the top of the glass lens. By observing the displacement scale of the scale 1 512 upward on the support frame 5, the center thickness of the glass lens can be measured. Furthermore, when the four positioning plates 3 are in contact with the glass lens, by observing the corresponding scale of two symmetrical positioning plates 3 and the scale 2 7, the diameter of the glass lens can be obtained. Thus, the center height and diameter of the glass lens can be measured simultaneously, thereby improving the detection efficiency.

[0038] Example 2

[0039] like Figures 1-5 As shown, based on the above embodiments, this embodiment further provides the following:

[0040] In the embodiment, the driving mechanism 4 comprises a guide rod 41, a connecting shell 42, articulated rods 43, a driving piece 44 and a reset piece 45. The vertical guide rod 41 is fixedly installed on the top wall of the installation cavity 23 and between the four sliding grooves 21. The connecting shell 42 is movably sleeved on the bottom of the guide rod 41. The four annularly arranged articulated rods 43 are hingedly connected to the outer side wall of the connecting shell 42. The other ends of the four articulated rods 43 are respectively hingedly connected to the four sliding blocks 22. The driving piece 44 is installed on the fixed shell 2 and extends into the installation cavity 23 and is connected to the connecting shell 42. The driving piece 44 is used to drive the connecting shell 42 to slide along the guide rod 41. The reset piece 45, which is connected to the connecting shell 42, is installed on the bottom wall of the installation cavity 23 and is used to drive the connecting shell 42 to slide upward along the guide rod 41. In use, the connecting shell 42 is driven to slide downward along the guide rod 41 by the driving piece 44. The four articulated rods 43 are all rotated around their hinge points on the connecting shell 42. The other ends of the four articulated rods 43 are respectively rotated relative to the four sliding blocks 22, so that the four sliding blocks 22 are respectively slid in the four sliding grooves 21 and approach each other. During this process, the stress state of the reset piece 45 changes. When the driving force of the driving piece 44 is removed, the reset piece 45 returns to the original state, thereby driving the connecting shell 42 to slide upward along the guide rod 41 and resetting, and driving the four sliding blocks 22 to respectively slide in the four sliding grooves 21 and move away from each other.

[0041] In the embodiment, the driving piece 44 comprises a fixed plate 441 fixedly installed on the fixed shell 2. A horizontal rotating rod 442 is rotatably installed on the fixed plate 441. One end of the rotating rod 442 extends into the installation cavity 23 and is coaxially connected with a gear 443. A vertical guide column 446 is fixedly installed on the bottom wall of the installation cavity 23. A connecting block 444, which is fixedly connected to the bottom of the connecting shell 42, is slidably installed on the guide column 446 along the axial direction of the guide column 446. A vertical rack 445 is fixedly installed on one end of the connecting block 444 and between the opposite sides of the two articulated rods 43. The rack 445 is engaged with the gear 443. In use, a rotating force is applied to the rotating rod 442. When the rotating rod 442 rotates, the gear 443 rotates, thereby driving the connecting block 444 to slide downward on the guide column 446 through the rack 445, so as to drive the connecting shell 42 to slide downward along the guide rod 41. The operation is simple.

[0042] In the embodiment, the reset member 45 comprises a horizontal plate 451 fixedly installed on one side of the connecting shell 42 below the hinged rod 43, and a spring telescopic rod 452 vertically fixedly installed on the bottom wall of the installation cavity 23, with the top of the spring telescopic rod 452 fixedly connected to the bottom of the horizontal plate 451. In use, when the connecting shell 42 is displaced downward along the guide rod 41, the horizontal plate 451 is displaced downward, thereby exerting a downward pressure force on the spring telescopic rod 452, and the spring telescopic rod 452 is deformed under the force. When the rotating force on the rotating rod 442 is cancelled, the spring telescopic rod 452 returns to the natural state, thereby pushing the connecting shell 42 upward along the guide rod 41 through the horizontal plate 451.

[0043] Embodiment Three

[0044] As shown in the above embodiment, the embodiment further provides the following contents: Figures 1-5

[0045] In the embodiment, the fixed plate 441 is fixedly installed on the fixed shell 2 by screws and blocks the opening end of the installation cavity 23, and the rotating rod 442 is coaxially fixedly connected to the hand wheel 447 at one end outside the fixed shell 2. The special design of the fixed plate 441 fixedly installed on the fixed shell 2 by screws and blocking the opening end of the installation cavity 23 achieves the blocking effect of the opening end of the installation cavity 23 and the blocking effect of the components inside the installation cavity 23, so that the device is more reasonable. The design of the hand wheel 447 facilitates the exertion of a rotating force on the rotating rod 442.

[0046] In the embodiment, the support frame 5 has a support 53 fixedly installed on the top, and a vertical stand 54 fixedly installed on the top of the connecting plate 52 and movably penetrating the support 53 in a vertical direction. The stand 54 is externally sleeved with a spring 55, and the two ends of the spring 55 are respectively connected to the connecting plate 52 and the support 53. When the connecting plate 52 is pulled to displace the measuring rod 51 upward on the support frame 5, the stand 54 is displaced upward, and the spring 55 is deformed under the force. When the bottom of the measuring rod 51 contacts the top of the glass lens under the gravity of the spring 55 during the detection of the center thickness of the glass lens, a downward pressure force is exerted on the connecting plate 52, so that the bottom of the measuring rod 51 abuts against the top of the glass lens, improving the adhesion between the measuring rod 51 and the glass lens and the detection accuracy.

[0047] ​In the embodiment, the bottom ball of the measuring rod 51 is connected with the ball 6, through the design of the ball 6, when detecting the center thickness of the glass lens, the ball 6 at the bottom of the measuring rod 51 contacts with the top of the glass lens, when the four sliders 22 are close to each other to make the four positioning plates 3 contact with the glass lens to position the glass lens, during the displacement of the glass lens on the top of the fixed shell 2, the ball 6 rolls at the bottom of the measuring rod 51, so as to reduce the friction between the measuring rod 51 and the glass lens.
