[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] like Figures 1 to 3As shown, an optical lens cold processing polishing device according to an embodiment of the present invention includes a frame 1; a polishing mechanism 12 is mounted on the top of the frame 1; a pair of first support plates 13 are symmetrically arranged and fixedly connected to the middle of the frame 1; a support frame 14 is installed between the pair of first support plates 13; a pair of central shafts 15 are fixedly connected to the middle of the support frame 14; the central shafts 15 are rotatably connected to the middle of the first support plates 13; a sleeve 16 is slidably connected to the middle of the central shaft 15; a clamping plate 17 is fixedly connected to one adjacent end of each pair of sleeves 16; a groove 18 is provided on one opposite side of each pair of clamping plates 17; and a central shaft 15 is mounted on the middle of the central shaft 15. There is a first spring 19; during operation, when the lens needs to be polished, the clamping plate 17 is pulled to separate the pair of clamping plates 17 away from each other, and then the lens to be polished is placed between the pair of clamping plates 17. Then the clamping plates 17 are released so that the pair of clamping plates 17 are brought closer together under the elastic force of the first spring 19 and the lens is clamped in the middle. The edge of the lens will sink into the interior of the groove 18, so that it will not easily fall off due to pressure during polishing. With the above structure, the lens can be easily clamped, so that the lens remains stable during processing and the occurrence of lens falling and being damaged under pressure is reduced.
[0024] like Figures 1 to 3 As shown, the clamping plate 17 is made of elastic material; a fixed rail 2 is fixedly connected to the middle of the sleeve 16; the two ends of the fixed rail 2 are slidably connected to the middle of the support frame 14; a pair of sliders 21 are symmetrically arranged and slidably connected in the middle of the fixed rail 2; a fastening bolt 22 is threadedly connected to the top of the slider 21; an adjusting bolt 23 is threadedly connected to the middle of the slider 21; a connecting rod 24 is rotatably connected to the end of the adjusting bolt 23 facing the clamping plate 17; a groove 25 is opened on the side of the clamping plate 17 facing the fixed rail 2; the connecting rod 24 is slidably connected to the middle of the groove 25; during operation, when clamping lenses of different diameters, the sliders 21 can be slid to pull the connecting rod 24 on both ends of the clamping plate 17, so that the two ends of the clamping plate 17... The end is subjected to force and undergoes elastic bending, thereby changing the curvature of the clamping plate 17. By adjusting the rotation of the bolt 23, the curvature of the clamping plate 17 can be made more flexible. After the adjustment is completed, rotating the fastening bolt 22 generates a large frictional force between the slider 21 and the fixed rail 2, thereby fixing the slider 21 and preventing the curvature of the clamping plate 17 from changing easily. After changing the curvature of the clamping plate 17, the fit between the clamping plate 17 and the lens edge can be improved when clamping lenses of corresponding diameters. Through the above structure, the curvature of the clamping plate 17 can fit more closely with lenses of different diameters, thereby improving the clamping effect of lenses of different diameters, improving the applicability of the device, and reducing the occurrence of lenses falling off.
[0025] like Figures 1 to 4As shown, a pair of limiting holes 3 are provided in the middle of the first support plate 13; a pull rod 31 is slidably connected to the end of the central shaft 15; a connecting rod 32 is fixedly connected to the middle of the pull rod 31; a pair of insert rods 33 are fixedly connected to the side wall of the connecting rod 32; a second spring 34 is fixedly connected to the middle of the central shaft 15; the other end of the second spring 34 is fixedly connected to the side wall of the connecting rod 32. During operation, after polishing one side of the lens, the pull rod 31 is pulled away from the central shaft 15, causing the insert rods 33 to disengage from the inside of the limiting holes 3. Then, the pull rod 31 is rotated to drive the central shaft 15 to rotate, thereby flipping the lens. Then, the pull rod 31 is released to allow the insert rods 33 to be inserted into the inside of the limiting holes 3, so that the support frame 14 will no longer rotate easily. With the above structure, the lens can be easily flipped without removing the lens and clamping it, improving the ease of use of the device.
[0026] like Figures 1 to 4 As shown, a guide rail 4 is fixedly connected to the bottom of the frame 1; a slide plate 41 is slidably connected to the middle of the guide rail 4; a second support plate 42 is fixedly connected to the top of the slide plate 41; during operation, after the support frame 14 is flipped, the slide plate 41 is slid to move the second support plate 42 to the bottom of the support frame 14, so that when the lens is polished, the middle part of the support frame 14 and the central shaft 15 tends to bend and deform due to pressure, and is supported by the second support plate 42. Through the above structure, the occurrence of deformation of the middle part of the support frame 14 and the central shaft 15 under pressure can be reduced, thereby reducing the impact of deformation on the polishing accuracy of the lens.
[0027] like Figures 1 to 4 As shown, an adjusting plate 5 is slidably connected to the middle of the first support plate 13; a groove 51 is provided on the side wall of the slide plate 41; an elastic band 52 is fixedly connected between a pair of slide plates 41; a connecting plate 53 is fixedly connected to the top of the side wall of the adjusting plate 5; the connecting plate 53 is rotatably connected to the middle of the pull rod 31; during operation, when it is necessary to flip the support frame 14, pulling the pull rod 31 can drive the connecting plate 53 to move, and the pair of slide plates 41 are moved away from each other by the squeezing of the pair of grooves 51 by the adjusting plate 5, thereby causing the second support plate 42 to move away from the support. When the support frame 14 moves away from below, it can be flipped over. When the insertion rod 33 is inserted into the limiting hole 3, the adjusting plate 5 moves away from the inclined groove 51. At this time, a pair of second support plates 42 will move closer to each other under the tension of the elastic band 52 and support the support frame 14 again. With the above structure, when the support frame 14 needs to be flipped, the second support plates 42 can be automatically moved away from below the support frame 14, reducing the obstruction to the rotation of the support frame 14 and improving the ease of use of the device.
[0028] like Figures 1 to 2As shown, an adjusting nut 6 is threadedly connected to the center of the central shaft 15; the adjusting nut 6 is located between the first support plate 13 and the first spring 19; during operation, when clamping lenses of different diameters, insufficient clamping force or excessive clamping force may occur. At this time, the adjusting nut 6 can be rotated to adjust the compression degree of the first spring 19, thereby adjusting the clamping force of the lens. Through the above structure, the clamping force of the device on lenses of different diameters can be adjusted, improving the applicability of the device.
[0029] like Figure 4 As shown, multiple rollers 7 are rotatably connected to the side wall of the adjusting plate 5; the multiple rollers 7 are arranged on the side of the adjusting plate 5 facing the inclined groove 51; through the above structure, the sliding friction between the adjusting plate 5 and the inclined groove 51 can be transformed into rolling friction, reducing the wear of components and making the use of the device more labor-saving.
[0030] During operation, when polishing a lens is required, pull the clamping plates 17 to separate them, then place the lens to be polished between the clamping plates 17. Then release the clamping plates 17, causing them to move closer together under the force of the first spring 19, clamping the lens in the middle. The edge of the lens will sink into the groove 18, preventing it from easily falling off due to pressure during polishing. When clamping lenses of different diameters, slide the slider 21 to pull the connecting rod 24 on both ends of the clamping plates 17, causing them to bend elastically under force, thereby changing the... The curvature of clamping plate 17 can be adjusted more flexibly by rotating bolt 23. After adjustment, rotating fastening bolt 22 generates greater friction between slider 21 and fixed rail 2, thereby fixing slider 21 and preventing the curvature of clamping plate 17 from easily changing. After changing the curvature of clamping plate 17, the fit between clamping plate 17 and lens edge can be improved when clamping lenses of corresponding diameters. After polishing one side of the lens, pull rod 31 is pulled away from the central axis 15, causing insertion rod 33 to disengage from the limiting hole 3. Then, the pull rod 31 is rotated to... The central axis 15 rotates, causing the lens to flip. Then, the pull rod 31 is released, allowing the insertion rod 33 to be inserted into the limiting hole 3, preventing the support frame 14 from easily rotating. After the support frame 14 is flipped, the sliding plate 41 moves the second support plate 42 to the bottom of the support frame 14. Thus, when the lens is polished, the support frame 14 and the central axis 15 tend to bend and deform under pressure, and the middle part is supported by the second support plate 42. When it is necessary to flip the support frame 14, pulling the pull rod 31 can move the connecting plate 53. By adjusting the pressure of the plate 5 on the pair of inclined grooves 51, the lens can be flipped. When a pair of sliding plates 41 move away from each other, the second support plate 42 moves away from under the support frame 14. At this time, the support frame 14 can be flipped. When the insertion rod 33 is inserted into the limiting hole 3, the adjusting plate 5 moves away from the inclined groove 51. At this time, the pair of second support plates 42 will move closer to each other under the tension of the elastic band 52 and support the support frame 14 again. When clamping lenses of different diameters, there may be insufficient clamping force or excessive clamping force. At this time, the adjusting nut 6 can be rotated to adjust the compression of the first spring 19, thereby adjusting the clamping force of the lens.
