[0024] 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. Example

[0025] Please see Figure 1-3 This embodiment provides the following technical solution: an optical lens grinding fixture, including a ball core body 1, with multiple lens slots 2 distributed circumferentially on the side wall of the ball core body 1. Through the lens slots 2, multiple lenses can be placed in different lens slots 2 at the same time, so that the ball core body 1 and the grinding dish cooperate with each other to grind multiple lenses on the ball core body 1 at the same time, thereby improving the grinding efficiency and grinding effect of the lenses.

[0026] In some embodiments, a buffer layer 8 is provided on the side wall inside the lens slot 2.

[0027] A lens placement mechanism is fixedly connected inside the lens slot 2. The placement mechanism includes a fixed plate 3, a movable plate 4, and a placement platform 5. A fixing groove 9 for the fixed plate 3 to be inserted is provided inside the lens slot 2. A fixing ring 10 is fixedly connected to the side wall of the fixed plate 3. The fixing ring 10 is detachably connected inside the lens slot 2. The fixed plate 3 can be fixed to the lens slot 2 by bolts through the fixing ring 10.

[0028] The movable disk 4 is slidably connected inside the fixed disk 3. The placement platform 5 is fixedly connected to the movable disk 4 and slidably connected to the fixed disk 3. A buffer assembly 6 is provided between the placement platform 5 and the fixed disk 3. A buffer pad 7 is provided above the placement platform 5. Through the placement mechanism, after the lens is placed in the lens slot 2 on the grinding ball core, the grinding dish and the grinding ball core cooperate to grind the lens. During the grinding process, the impact force generated by the interaction between the grinding ball core and the grinding dish is absorbed and dispersed, avoiding lens breakage or surface scratches caused by impact force, thus improving the grinding quality of the lens.

[0029] In some embodiments, multiple buffer components 6 are provided, and the multiple buffer components 6 are circumferentially distributed inside the fixed disk 3, which can uniformly buffer the placement platform 5 and limit the movement direction of the placement platform 5.

[0030] The buffer assembly 6 includes a fixed cylinder 601, a movable cylinder 602, and an elastic element 603. The fixed cylinder 601 is fixedly connected to the fixed plate 3. A movable plate is slidably connected inside the fixed cylinder 601. One side of the movable plate is fixedly connected to the movable cylinder 602. The other end of the movable cylinder 602 extends through the outside of the fixed cylinder 601 and is fixedly connected to the placement platform 5. The elastic element 603 is disposed between the fixed cylinder 601 and the movable cylinder 602. In some embodiments, the elastic element 603 is a buffer spring. The buffer spring is sleeved on the movable cylinder 602 and located outside the fixed cylinder 601. One end of the buffer spring is fixedly connected to the movable cylinder 602, and the other end of the buffer spring is fixedly connected to the fixed cylinder 601. By setting the fixed cylinder 601, the movable cylinder 602, and the elastic element 603, the impact force received during lens grinding can be absorbed and dispersed, thereby improving the grinding quality of the lens during the grinding process.

[0031] A chip removal groove 11 is provided on one side of the bottom of the lens holder 2. The chip removal groove 11 can discharge the residue and polishing fluid in the lens holder 2, so as to avoid the residue or polishing fluid remaining in the lens holder 2 and affecting the subsequent lens polishing process.

[0032] The chip removal trough 11 is detachably connected to a chip removal hopper 12, which is provided with a collection chamber. The chip removal hopper 12 and the collection chamber facilitate the collection of residues and polishing fluid in the lens slot 2, making it easy to handle manually.

[0033] The working principle of this utility model is as follows: In use, the worker puts the lenses to be ground into the corresponding lens slots 2 in sequence, so that the lenses are attached to the buffer pads 7 above the placement table 5. Then, the ball core body 1 cooperates with the grinding dish to grind the lenses on the ball core body 1. When the lens is subjected to impact force, the placement table 5 will drive the movable disk 4 and the movable cylinder 602 to move inward. With the cooperation of the elastic element 603, the movable cylinder 602 plays a buffering role for the movable cylinder 602, the movable disk 4 and the placement table 5, thereby absorbing and dispersing the impact force on the lens.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
