Description

Technical Field

[0001] The utility model belongs to the technical field of lens grinding, and in particular relates to a lens grinding device with controllable grinding position. Background Art

[0002] Lenses are made by mixing high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, and barium according to a specific formula. These are then melted in a platinum crucible at high temperature and stirred evenly with ultrasonic waves to remove air bubbles. The glass is then slowly cooled over a long period of time to prevent internal stress in the glass. The cooled glass is then measured with optical instruments to verify its purity, transparency, uniformity, refractive index, and dispersion. Qualified glass blocks are then heated and forged to form optical lens blanks.

[0003] There are often some limitations in existing lens grinding devices. For example, the accuracy of the grinding position is difficult to effectively control, resulting in unstable grinding quality, possible deviations, unevenness and other problems, affecting the optical performance and use effect of the lens, and it is difficult to meet various complex grinding needs.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0027] The following will clearly and completely describe the technical solutions in the utility model embodiments in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the utility model embodiments, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of utility model protection.

[0028] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0029] See also Figures 1-6 As shown, the utility model is a lens polishing device with a controllable polishing position, comprising a base 1, a position control component 2 being slidably installed inside the base 1, a telescopic component 3 being fixedly installed between the two ends of the position control component 2, the middle part of the position control component 2 being rotatably installed on the base 1, a lifting component 4 being rotatably installed on the top of the base 1, a polishing component 5 being threadedly installed on the other end of the lifting component 4, a sliding rod 6 being slidably installed on the other end of the polishing component 5, and the bottom of the sliding rod 6 being fixedly installed on the base 1.

[0030] During use, the lens is first placed on the top of the base 1 and on the central axis of the positioning control component 2. Then the telescopic component 3 will drive the fixed positioning control component 2 to move. At this time, the positioning control component 2 will show that its four corners move closer to each other, thereby synchronously controlling the circumferential surface of the lens on its central axis. In addition, the movement of the four corners of the positioning control component 2 closer to each other can also adapt to lenses of different sizes, so that the grinding position of the lens can be effectively controlled during grinding. Then the lifting component 4 is driven to rotate, and then the rotation of the lifting component 4 will drive the grinding component 5 threadedly mounted thereon to move. At the same time, the grinding component 5 will move smoothly toward the top position of the lens under the guidance of the sliding rod 6. In addition, the grinding component 5 is driven to rotate. When the grinding component 5 contacts the top of the lens, the positioned lens can be polished by rotating the grinding component 5.

[0031] By placing the lens on the central axis of the positioning assembly 2, and then driving the telescopic assembly 3 to move the four corners of the positioning assembly 2 closer to each other, the circumferential surface of the lens on the central axis is synchronously positioned, thereby avoiding the problem of unstable grinding quality, possible deviation, and unevenness caused by the inability to effectively control the accuracy of the lens grinding position, and the device can adapt to the grinding of lenses of different sizes.

[0032] Thus, by driving the lifting assembly 4 to move the grinding assembly 5, the rotating grinding assembly 5 is brought into contact with the top of the lens and grinds the lens, thereby avoiding the inaccuracy of manual lens grinding.

[0033] In one embodiment, for the above-mentioned base 1 , the base 1 includes a shell 101 , and support legs 102 are fixedly installed at the four corners of the bottom of the shell 101 .

[0034] The supporting legs 102 are used to support the housing 101 to ensure stable operation of the device.

[0035] In one embodiment, for the above-mentioned position control component 2, the position control component 2 includes a fixed rod 201, which is rotatably installed on the top of the inner cavity of the shell 101, and a driving block 202 is fixedly installed on the bottom of the fixed rod 201, and the four corners of the driving block 202 are rotatably installed with rotating rods 203.

[0036] The rotating rods 203 are arranged in an L shape. The other ends of the four rotating rods 203 are rotatably mounted with rotating shafts 204 , and the tops of the rotating shafts 204 are fixedly mounted with control rods 205 .

[0037] The telescopic assembly 3 includes two linkage rods 301 , which are respectively fixedly mounted on the bottoms of two symmetrical control rods 205 , and a telescopic rod 302 is fixedly mounted between the two linkage rods 301 .

[0038] When in use, it is necessary to place the lens on the central axis position of the four control rods 205, and then drive the telescopic rod 302 to drive the linkage rods 301 at both ends to move, and then the two linkage rods 301 will drive the control rods 205 fixedly installed on them to move. At the same time, the movement of the two control rods 205 will drive the rotating shafts 204 fixedly installed on them to rotate, and then the rotating shafts 204 will drive the rotating rods 203 installed in rotation to rotate, and then the two rotating rods 203 will simultaneously drive the driving blocks 202 installed in rotation to rotate, and then the driving blocks 202 will drive the fixed rods 201 fixedly installed on the outside. When the lens is rotated under the support of the housing 101, the rotation of the driving block 202 will simultaneously drive the rotating rods 203 at the four corners to rotate. Since the rotating rods 203 are set in an L shape, the rotating rods 203 drive the rotating shaft 204 and the control rods 205 to move. At this time, the four control rods 205 will move toward the circumferential surface of the lens, and then the circumferential surface of the lens will be synchronously controlled, thereby avoiding the problem of unstable polishing quality, possible deviation, and unevenness caused by the inability to effectively control the accuracy of the lens polishing position. In addition, the synchronous movement of the four control rods 205 can also adapt to lenses of different sizes.

[0039] In one embodiment, for the above-mentioned lifting assembly 4, the lifting assembly 4 includes a servo motor 401, the servo motor 401 is rotatably mounted on the housing 101, a threaded rod 402 is fixedly mounted on the top of the servo motor 401, a connecting rod 403 is threadedly mounted on the circumferential surface of the threaded rod 402, and the other end of the connecting rod 403 is slidably mounted on the sliding rod 6.

[0040] The grinding assembly 5 includes a driving motor 501 , a driving shaft 502 is fixedly mounted on the output end of the driving motor 501 , and a grinding block 503 is fixedly mounted on the other end of the driving shaft 502 .

[0041] After the lens is positioned, the threaded rod 402 fixedly installed at the output end of the servo motor 401 can be driven to rotate, and then the threaded rod 402 will drive the threaded connecting rod 403 to move under the guidance of the sliding rod 6. At the same time, the driving motor 501 will drive the driving shaft 502 to rotate, and then the driving shaft 502 will drive the fixedly installed grinding block 503 to rotate. When the grinding block 503 contacts the lens, the rotating grinding block 503 will grind the lens, thereby avoiding the inaccuracy of manual grinding of the lens.
