Description

Technical Field

[0001] This utility model relates to the field of lens grinding technology, specifically to a lens centering and edge grinding machine. Background Technology

[0002] A lens is an optical element made of transparent material (such as glass, crystal, etc.). Common types include convex lenses (thick in the middle and thin at the edges, with three types: biconvex, plano-convex, and concave-convex) and concave lenses (thin in the middle and thick at the edges, with three types: biconcave, plano-concave, and convex-concave).

[0003] Lenses need to be cut during production, and after cutting, their edges need to be polished using a centering edge grinding machine. Most existing lens centering edge grinding machines polish the edges of the lens using a grinding wheel. After a period of use, the polishing performance of the grinding wheel decreases, requiring the use of screws and screwdrivers for disassembly and replacement. Furthermore, because the grinding wheel is relatively thin, replacement is quite frequent, resulting in less than ideal performance.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

A top frame 2 is provided on the top of the frustum 1. A first electric telescopic rod 3 is installed in the middle of the top surface of the top frame 2. A pressure piece 4 is threadedly connected to the bottom end of the first electric telescopic rod 3. This pressure piece 4 is replaceable, and the appropriate size can be selected according to the size of the lens, making it flexible and effective. A placement platform 5 is threadedly connected to the middle of the top surface of the frustum 1, which can hold the lens and has a height adjustment function, allowing full utilization of the outer wall of the grinding long sleeve 15 and greatly improving its service life. A lifting platform 27 is provided on the top surface of the frustum 1, which is slidably connected to it. Multiple annularly distributed long grooves 6 are opened on the top surface of the lifting platform 27. A centering slider 7 is slidably connected inside each long groove 6, and each centering slider 7 is fixedly connected to the inner wall of the long groove 6. Spring 8, the lifting platform 27 has a first cavity 9 inside, the bottom of the truncated cone 1 is equipped with a second electric telescopic rod, the top of the second electric telescopic rod is fixedly connected to the bottom of the lifting platform 27, which can drive the lifting platform 27 to move up and down, which can avoid interference with the centering slider 7. The first cavity 9 is equipped with a centering mechanism connected to the centering slider 7. The top surface of the truncated cone 1 is rotatably connected with a rotating structure. The top of the rotating structure is fixedly installed with a boss 10. The end of the boss 10 near the placement platform 5 is slidably connected with a slide bar 11. The bottom end of the slide bar 11 is equipped with a first motor. The top of the slide bar 11 is equipped with a grinding component that is driven and connected to the first motor. The end of the boss 10 away from the placement platform 5 is equipped with a threaded screw rod 12 that is threadedly connected to it. The threaded screw rod 12 and the slide bar 11 are rotatably connected.

[0019] Example 2; like Figure 1-5 As shown, according to an embodiment of the present invention, the lens centering and edging machine includes a grinding assembly comprising a rotating block 13 connected to the top of a first motor. The top surface of the rotating block 13 is provided with a limiting disc 14 threadedly connected thereto. The rotating block 13 is fitted with a matching grinding sleeve 15, which is long in height and has a long service life, eliminating the need for frequent replacement. The inner wall of the grinding sleeve 15 is integrally connected with four annularly distributed limiting strips 16, which are engaged with the top surface of the rotating block 13. The bottom surface of the limiting disc 14 presses against the top surface of the limiting strips 16, making the grinding sleeve 15 easy to replace. The top surface of the limiting disc 14 is provided with an elastic telescopic post, which is normally in a retracted state. The top surface of the elastic telescopic post is provided with a gripping protrusion 17, and the bottom end of the gripping protrusion 17 is provided with a limiting insertion post 18. The top surface of the rotating block 13 is provided with a limiting insertion hole 19 that matches the limiting insertion post 18, which serves as a limiting function and ensures the stability of the limiting disc 14 after it is tightened.

[0020] Example 3; like Figure 1-5As shown, according to an embodiment of the present invention, the lens centering and edging machine has a rotating structure including an outer gear ring 20 embedded in the top surface of a frustum 1. The outer gear ring 20 is rotatably connected to the frustum 1. A gear 21 is provided on one side of the outer gear ring 20 and meshes with it. A second motor 22 is connected to the top of the gear 21. A second cavity is provided inside the frustum 1. The second motor 22 is installed on the upper inner wall of the second cavity. The outer gear ring 20 extends into the second cavity and can rotate, thereby driving the entire grinding assembly to move circumferentially, resulting in uniform and extensive grinding.

[0021] Example 4; like Figure 1-5 As shown, according to an embodiment of the present invention, the lens centering and edging machine includes a lifting ring 23. Multiple traction ropes 24 are fixedly connected to the outer wall of the lifting ring 23. Each traction rope 24 is correspondingly fixedly connected to a centering slider 7.

[0022] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0023] In practical applications, a suitable pressure piece 4 is selected and threadedly fixed to the first electric telescopic rod 3 according to the size and shape of the lens to be ground. The placement table 5 is rotated so that it protrudes to a suitable height. The lens to be ground is placed on the placement table 5. The forward rotation of the adjustment knob drives the adjustment screw 25 to rotate forward (the bottom of the lifting platform 27 is open and will not interfere with the operator's rotation of the adjustment knob). At this time, the lifting ring 23 slides down and pulls all the traction ropes 24. Each centering slider 7 moves closer to the placement table 5 and achieves the centering positioning of the lens. The first electric telescopic rod 3 is activated to drive the pressure piece 4 to move down and press against the top surface of the lens. The reverse adjustment knob is then activated. At this time, the traction ropes 24 lose their pull. Under the elastic force of the spring 8, each centering slider 7 moves away from the placement table 5 and resets. The second... The electric telescopic rod drives the entire lifting platform 27 to move downward, which can prevent the centering slider 7 from affecting the grinding mechanism. Finally, the first motor is started to drive the grinding sleeve 15 to rotate at high speed. The forward rotation of the threaded screw rod 12 drives the grinding sleeve 15 to fit against the edge of the lens. The second motor 22 is started to drive the gear 21 to rotate. The gear 21 drives the outer gear ring 20 to rotate. The entire grinding mechanism moves in a circle to achieve edge grinding. When the grinding effect deteriorates, the placement platform 5 is rotated forward and the appropriate height is adjusted so that the edge of the lens contacts the unused surface of the grinding sleeve 15. When all surfaces of the grinding sleeve 15 have been used, the gripping protrusion 17 is lifted upward to separate the limiting insertion post 18 from the limiting insertion hole 19. The gripping protrusion 17 is reversed to drive the limiting disc 14 to rotate and be removed. At this time, the grinding sleeve 15 loses its limiting position and can be lifted and removed directly.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
