Description

Technical Field

[0001] The present invention relates to the technical field of optical glass grinding, in particular to a double-sided grinding and polishing device for optical glass processing. Background Art

[0002] Double-sided grinding and polishing of optical lenses is a core process in modern optical manufacturing. Its goal is to efficiently remove material while ensuring that the two surfaces achieve extremely high flatness, parallelism and a certain surface roughness to facilitate related use.

[0003] Planetary double-sided grinding machines are commonly used for double-sided grinding and polishing of optical lenses. Their core principle is to move the workpiece through a complex planetary motion between two counter-rotating grinding discs, achieving uniform and efficient material removal. The workpiece is mounted on a planetary wheel or planetary gear. The planetary wheel is a gear-like carrier that rotates and revolves around itself under the combined action of internal and external gear rings, facilitating the grinding and polishing process.

[0004] However, the planetary double-sided grinder used in existing optical lenses has the following shortcomings: although the existing planetary double-sided grinder relies on the cooperation of inner and outer gear rings and gear-shaped cruise ships to realize the rotation and revolution of the workpiece for grinding and polishing, metal debris will be generated during the meshing transmission process of the gears. If these debris enter the grinding area, they will seriously scratch the lens. The tiny gaps between the gears will cause discontinuous movement and vibration, affecting the smoothness and consistency of grinding; the gears need to be lubricated, but there is a risk of lubricating oil leakage, which will contaminate the grinding fluid and the working environment; therefore, when the existing optical lenses use a planetary double-sided grinder, the gear transmission form is set, which is easy to affect the quality of lens grinding and polishing. Summary of the Invention

[0005] The purpose of the present invention is to provide a double-sided grinding and polishing device for optical glass processing, so as to solve the problem in the prior art that the optical lenses in the conventional technology are easily affected by the setting of the gear transmission form when using a planetary double-sided grinder, which affects the quality of the lens grinding and polishing.

A clamping drive mechanism is provided between each group of the clamping and tightening mechanisms and the downward pressing cover body mechanism.

[0007] Preferably, the rotation drive mechanism includes a supporting swivel and a driving gear set, the supporting swivel is rotatably connected to the supporting base, and the clamping and tightening mechanisms are circumferentially equidistantly distributed on the supporting swivel; the driving gear set is used to drive the supporting swivel to rotate.

[0008] Preferably, the driving gear set includes a first gear ring and a first driving gear, the first gear ring is coaxially fixedly connected to the outer ring of the supporting rotating ring, and the first driving gear is engaged with one side of the first gear ring.

[0009] Preferably, each group of the clamping and tightening mechanisms includes a mounting seat and a rotating clamping arm, the mounting seat is connected to the supporting swivel, two rotating clamping arms are provided, and are distributed in a V shape, one end of each rotating clamping arm is rotatably connected to the mounting seat, and the other end is rotatably connected to a wheel that cooperates with and contacts the corresponding cruise ship body; the clamping drive mechanism is used to drive the two rotating clamping arms to clamp.

[0010] Preferably, the outer ring of the cruise ship is provided with an annular groove that matches the runner.

[0011] Preferably, each group of the clamping drive mechanism includes a supporting guide rail and a U-shaped top block, the supporting guide rail is fixedly connected to the mounting seat in a corresponding horizontal direction, the U-shaped top block is slidably connected to the supporting guide rail, and the U-shaped top block is used to push the corresponding two rotating clamping arms at the same time, a linkage pressure ring is arranged parallel to the top of the supporting swivel, and a plurality of linkage rods are circumferentially equidistantly distributed at the bottom of the linkage pressure ring, one end of each linkage rod is movably connected to the linkage pressure ring through a hinge, and the other end is movably connected to the corresponding U-shaped top block through a hinge, and the downward pressing cover body mechanism includes a plurality of downward pressing cross plates circumferentially equidistantly distributed, and each of the downward pressing cross plates is aligned with the linkage pressure ring.

[0012] Preferably, elastic telescopic rods are connected between the two sides of the linkage pressure ring and the supporting rotating ring.

[0013] Preferably, the downward pressing cover body mechanism includes a cylindrical cover body and a lifting electric guide rail, the lifting electric guide rail is vertically fixedly installed on the support base, the cylindrical cover body is slidingly connected to the lifting electric guide rail, and the bottom of the cylindrical cover body is spliced ​​with an elastic corrugated telescopic sleeve.

[0016] Beneficial effects of the present invention: The present invention eliminates the sun gear and ring gear of the existing planetary double-sided grinder, so that the cruise ship does not need to be driven by gear-shaped internal and external teeth.

Then, the distributed clamping and tightening mechanisms can be driven by the rotary drive mechanism to rotate around the fixed friction wheel. In this way, each cruise ship can roll around the fixed friction wheel by relying on the friction force generated during the tightening, thereby realizing self-rotation and revolution, and the movement is smooth, ensuring that the grinding and polishing are effectively completed. There is no need to use gear-type cruise ships to cooperate with the ring gear for revolution and rotation, which is easy to vibrate due to the gear gap, affecting the grinding and polishing effect. At the same time, it can also avoid the generation of metal debris that scratches the glass lens during the meshing transmission process of the gears; and it can also reduce the pollution caused by the use of lubricating fluid and the noise during the gear transmission process.

[0017] When the cylindrical cover body of the present invention descends to cover the grinding and polishing environment, the cylindrical cover body descends and relies on the downward pressure horizontal plate to squeeze the linkage pressure ring, and the linkage pressure ring relies on the distributed linkage rods to make all the U-shaped top blocks slide horizontally. Each U-shaped top block squeezes the corresponding two rotating clamping arms, causing the rotating clamping arms to clamp and squeeze the cruise ship body, thereby making it easier for the cruise ship body to contact the fixed friction wheel and be positioned. In this way, when the supporting ring rotates, all the cruise ship bodies can roll around the fixed friction wheel.

[0018] During the descent of the cylindrical cover body of the present invention, by relying on the downward pressure of the horizontal plate, the linkage pressure ring, the linkage rod and the U-shaped top block, all the rotating clamping arms distributed in a V shape can act on the cruise ship body, so that the cruise ship body can be quickly positioned, and the corresponding radial extrusion force can be applied to the cruise ship body to ensure that the cruise ship body is tightly pressed against the fixed friction wheel, thereby ensuring that the corresponding friction force can be generated to realize rotation and revolution, and there is no need to perform multiple position adjustments on the cruise ship body separately, thereby improving the convenience of operation.

[0021] The specific embodiments of the present invention are described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0022] like Figures 1-8As shown, a double-sided grinding and polishing device for optical glass processing is improved based on the existing planetary double-sided grinding machine, including a support base 1, a lower grinding turntable 17, an upper grinding turntable 8 and a cruise wheel body 15 for loading a glass lens 16. A retainer is provided inside the cruise wheel body 15. The retainer is an elastic annular plastic body with an inner diameter slightly smaller than the outer diameter of the glass lens 16. In addition, the thickness of the glass lens 16 is greater than that of the cruise wheel body 15. Both its upper and lower surfaces can be exposed from the upper and lower sides of the cruise wheel body 15, facilitating grinding and polishing. The cruise wheel body 15 loaded with the glass lens 16 is placed on the lower grinding turntable 17, and then the lower grinding turntable 17 and the upper grinding turntable 8 clamp the placed cruise wheel body 15, and the lower grinding turntable 17 and the upper grinding turntable 8 rotate in opposite directions, so as to facilitate the grinding and polishing of the upper and lower surfaces of the multiple glass lenses 16; and the lower grinding turntable 17 and the upper grinding turntable 8 can be set as an annular base plate and an abrasive disc, and the abrasive disc is fixedly connected to the annular base plate by bolts and other connecting parts, so that the abrasive disc can be replaced. When performing different stages of grinding and polishing, The abrasive disc of corresponding specifications can be replaced, so as to facilitate the completion of grinding and polishing in sequence; the equipment also includes a friction type rotary drive mechanism and a downward pressure cover mechanism; the friction type rotary drive mechanism includes a fixed friction wheel 18 and a clamping and tightening mechanism, the fixed friction wheel 18 is arranged at the center position of the lower grinding turntable 17, and the fixed friction wheel 18 is fixed relative to the support base 1, specifically, the support base 1 can be vertically fixedly connected with a fixed column 14, and the center positions of the upper grinding turntable 8 and the lower grinding turntable 17 are provided with a through hole for the fixed column 14 to pass through, and the fixed friction wheel 18 is fixed. The wheel 18 can be coaxially fixedly connected to the fixed column 14; there are multiple groups of clamping and tightening mechanisms, each of which is used to clamp the corresponding cruise wheel body 15 and radially press the corresponding cruise wheel body 15 onto the fixed friction wheel 18. The cruise wheel body 15 is an annular disc body, and the support base 1 is provided with a rotary drive mechanism for driving each group of clamping and tightening mechanisms to rotate synchronously around the fixed friction wheel 18. This makes it convenient for all the cruise wheel bodies 15 to rotate on their own by relying on the friction force generated during tightening, and also to revolve around the fixed friction wheel 18, thereby facilitating the completion of the grinding and polishing process. There is no need to use a gear-type cruise wheel to cooperate with a gear ring for orbital rotation, so as to avoid the generation of metal debris during the meshing transmission process of the gears, because if these debris enter the grinding area, they will seriously scratch the glass lens 16; and it can also reduce the pollution caused by the use of lubricating fluid and the noise during the gear transmission process; The downward pressing cover body mechanism is arranged in a liftable manner on the supporting base 1. The downward pressing cover body mechanism is used to cover the lower grinding turntable 17 and the upper grinding turntable 8 that clamp the cruise ship body 15, so as to prevent the dust generated during the grinding process from spreading to the surrounding environment and causing pollution. A clamping drive mechanism is provided between each set of clamping and tightening mechanisms and the downward pressing cover body mechanism. During the descent process of the downward pressing cover body mechanism, the clamping and tightening mechanism is clamped by the clamping drive mechanism, and there is no need to operate the clamping cruise ship body 15 separately.

[0023] It should be noted that both the cruise wheel body 15 and the fixed friction wheel 18 can be made of polyurethane material, and the outer ring of the fixed friction wheel 18 is distributed with a circle of anti-skid grooves to ensure that the cruise wheel body 15 has a certain degree of anti-skid property when contacting the fixed friction wheel 18.

[0024] In some embodiments, combined Figure 2 and Figure 3 As shown, the rotary drive mechanism includes a supporting swivel 12 and a driving gear set. The supporting swivel 12 is rotatably connected to the supporting base 1 and is concentrically aligned below the lower grinding turntable 17. Specifically, an annular groove can be opened on the supporting base 1. The cross-section of the annular groove is a T-shaped surface. The supporting swivel 12 can be slidably connected to the annular groove through a pulley or a slider; the clamping and tightening mechanisms are equidistantly distributed on the supporting swivel 12 in the circumferential direction; the driving gear set is used to drive the supporting swivel 12 to rotate.

[0025] Among them, the driving gear set includes a first gear ring 10 and a first driving gear 11. The first gear ring 10 is coaxially fixedly connected to the outer ring of the support swivel 12. The first driving gear 11 is engaged with one side of the first gear ring 10, and the first driving gear 11 is driven to rotate by a motor, and the motor can be fixedly installed on the support base 1.

[0026] The first driving gear 11 drives the first gear ring 10 to rotate, so that the first gear ring 10 drives the supporting rotating ring 12 to rotate around the fixed column 14, thereby driving the distributed clamping and tightening mechanisms to rotate.

[0027] In some embodiments, combined Figures 4 to 6 As shown, each set of clamping and tightening mechanisms includes a mounting seat 20 and a rotating clamping arm 19. The mounting seat 20 is connected to the supporting swivel 12. There are two rotating clamping arms 19, which are distributed in a V shape. One end of each rotating clamping arm 19 is rotatably connected to the mounting seat 20 through a rotating shaft, and the other end is rotatably connected to a runner 21 that contacts with the corresponding cruise ship body 15. The clamping drive mechanism is used to drive the two rotating clamping arms 19 to clamp together. When the two rotating clamping arms 19 clamp together, they rely on the runner 21 at the end to squeeze from both sides of the cruise ship body 15, and the end of the rotating clamping arm 19 contacts the cruise ship body 15. The position of the wheel body 15 does not exceed the center position of the cruise ship body 15. Since the cruise ship body 15 is an annular disk, the cruise ship body 15 will move radially during the squeezing process, so as to facilitate contact with the fixed friction wheel 18. In this way, during the rotation of the supporting swivel 12, the two corresponding rotating clamping arms 19 of each group can clamp the cruise ship body 15 and revolve around the fixed friction wheel 18. Since the rotating clamping arms 19 contact the cruise ship body 15 by relying on the rotating wheels 21 at the ends, and the cruise ship body 15 is pressed against the fixed friction wheel 18, it can rely on friction to achieve rotation during the revolution.

[0028] It should be noted that a coil spring or other similar resilient member may be provided at one end of the rotating clamp arm 19 that is rotatably connected to the mounting seat 20 to ensure that when the rotating clamp arm 19 is released, the two rotating clamp arms 19 can automatically reset and open.

[0029] In addition, in some implementation schemes, the mounting seat 20 can also be connected to the support swivel 12 through a height adjustment member. The height adjustment member can be a screw and a nut used in combination to adjust the height of the mounting seat 20 to ensure that the rotating clamp arm 19 can contact the cruise ship body 15.

[0030] It should also be noted that in order to facilitate the rotating clamp arm 19 to install the end of the runner 21 so that it can effectively contact the outer ring of the cruise ship body 15, a circle of annular grooves can be provided on the outer ring of the cruise ship body 15 to facilitate the runner 21 to be stuck into the annular groove.

[0031] In some specific embodiments, reference Figure 5 As shown, each set of clamping drive mechanisms includes a support guide rail 22 and a U-shaped top block 23. The support guide rail 22 is correspondingly and horizontally fixedly connected to the mounting seat 20, and the extension line of the support guide rail 22 passes through the central axis position of the fixed friction wheel 18; the U-shaped top block 23 is slidably connected to the support guide rail 22, and the U-shaped top block 23 is used to push the corresponding two rotating clamping arms 19 at the same time, and the U-shaped opening of the U-shaped top block 23 is horizontally aligned with the fixed friction wheel 18; a linkage pressure ring 13 is arranged parallel above the support swivel 12, and the linkage pressure ring 13 is concentrically distributed with the support swivel 12. A plurality of linkage rods 24 are circumferentially equidistantly distributed at the bottom of the linkage pressure ring 13, one end of each linkage rod 24 is movably connected to the linkage pressure ring 13 by a hinge, and the other end is movably connected to the corresponding U-shaped top block 23 by a hinge, and the downward pressing cover body mechanism includes a plurality of downward pressing cross plates 9 circumferentially equidistantly distributed, and each downward pressing cross plate 9 is aligned with the linkage pressure ring 13.

[0032] When the glass lens 16 is fixedly installed in the cruise ship body 15 and the cruise ship body 15 is initially placed between the corresponding two rotating clamping arms 19, the downward pressure cover mechanism is lowered to cover the entire grinding and polishing space. During this process, the distributed downward pressure cross plates 9 are synchronously lowered. During the lowering process of the downward pressure cross plates 9, they abut against the linkage pressure ring 13, and the linkage pressure ring 13 descends relative to the support swivel 12. During this process, the linkage pressure ring 13 pushes the U-shaped top block 23 through the linkage rod 24 to move horizontally along the corresponding support guide rail 22, and the U-shaped top block 23 squeezes and pushes the corresponding two rotating clamping arms 19, thereby facilitating the squeezing of the corresponding cruise ship body 15, making it abut against the fixed friction wheel 18, and then the support swivel 12 drives the tightened cruise ship body 15 to rotate around the fixed friction wheel 18.

[0033] It should be noted that in order to facilitate the rotation of the linkage pressure ring 13 relative to the downward pressure horizontal plate 9, a pulley or a ball can be installed on the lower surface of each downward pressure horizontal plate 9, or the balls can be evenly distributed circumferentially on the upper surface of the downward pressure horizontal plate 9 to reduce the contact friction.

[0034] In some specific embodiments, a compressible elastic telescopic rod 27 is also connected between the two sides of the linkage pressure ring 13 and the support swivel 12. The elastic telescopic rod 27 includes a lower pressure rod fixedly connected to the linkage pressure ring 13 and a sleeve fixedly connected to the support swivel 12, and the lower pressure rod slides through the sleeve. At the same time, a compressible spring is also connected between the lower pressure rod and the sleeve to facilitate the linkage pressure ring 13 to move up and down smoothly relative to the support swivel 12.

[0035] In some specific embodiments, Figure 1 and Figure 2 As shown, the downward pressure cover mechanism includes a cylindrical cover body 3 and a lifting electric guide rail 2. The lifting electric guide rail 2 is vertically fixedly installed on the support base 1 and distributed in pairs. The cylindrical cover body 3 is slidably connected to the lifting electric guide rail 2. The inner diameter of the cylindrical cover body 3 can be designed according to the maximum size position reached by the actual component to ensure that all the above components can be covered. The bottom of the cylindrical cover body 3 is spliced ​​with an elastic corrugated telescopic sleeve 5, and the above-mentioned downward pressure cross plate 9 can be fixedly arranged on the inner wall of the cylindrical cover body 3 at equal intervals in the circumference; a negative pressure dust suction component 4 is also provided on the cylindrical cover body 3, and the negative pressure dust suction component 4 is connected to the internal space of the cylindrical cover body 3, which is convenient for sucking dust or debris generated in the grinding and polishing air. If grinding fluid or polishing fluid is used for treatment, the negative pressure dust suction component 4 may not be installed depending on the situation. In this case, the cylindrical cover body 3 is used to prevent the grinding fluid or polishing fluid from splashing out.

[0036] After the glass lens 16 is in place, the cylindrical cover 3 is controlled to descend to cover the entire grinding and polishing space. The elastic corrugated telescopic sleeve 5 at the bottom first contacts the surface of the support base 1 and is compressible, so that the cylindrical cover 3 can descend within a certain range.

[0037] In some embodiments, combined Figure 2 and Figure 3As shown, an electric telescopic rod 6 is fixedly installed on the inner top of the downward-pressing cover body mechanism, which can specifically make the electric telescopic rod 6 fixedly connected to the cylindrical cover body 3, the telescopic end of the electric telescopic rod 6 vertically downward, and the telescopic end of the electric telescopic rod 6 is fixedly installed with a drive motor 7 through a connecting frame, the main shaft end of the drive motor 7 vertically downward, and fixedly connected to the upper grinding turntable 8 through a U-shaped frame, the cylindrical cover body 3 can be set as a transparent body, and a pressure sensor is installed at the telescopic end of the electric telescopic rod 6, and a corresponding pressure collection and display device is provided. When the cylindrical cover body 3 descends to cover the assembled glass lens 16, the electric telescopic rod 6 is controlled to extend, so that it drives the upper grinding turntable 8 to descend to the upper surface of the glass lens 16, and at the same time, the contact between the upper grinding turntable 8 and the glass lens 16 is judged by the pressure value feedback from the pressure sensor.

[0038] In some embodiments, combined Figure 6 and Figure 7 As shown, there is a certain distance between the lower grinding turntable 17 and the support base 1, and a second gear ring 25 is coaxially fixedly connected to the bottom of the lower grinding turntable 17. When a fixed column 14 is provided, a support cylinder can be coaxially fixedly provided on the bottom of the lower grinding turntable 17, and the support cylinder is sleeved on the fixed column 14. The second gear ring 25 is fixed to the outer ring of the fixed column 14, and a limit retaining ring can also be fixedly provided on the fixed column 14. The limit retaining ring is located on the upper side of the lower grinding turntable 17, and its outer diameter is larger than the aperture of the middle through hole of the lower grinding turntable 17; a second driving gear 26 is engaged with one side of the second gear ring 25, and the second driving gear 26 is rotatably connected to the support base 1 through a rotating shaft, and the second driving gear 26 is driven by a motor fixedly mounted on the support base 1, and the second driving gear 26 drives the second gear ring 25 to rotate, thereby rotating the lower grinding turntable 17.

[0039] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in conjunction with specific application scenarios: First, each glass lens 16 is fixed and clamped into the cruise wheel body 15. Then, the cruise wheel body 15 is initially placed between the two rotating clamping arms 19 of each set of clamping and tightening mechanisms. At this time, the cruise wheel body 15 does not need to be pressed against the fixed friction wheel 18. Then, the cylindrical cover body 3 is lowered along the lifting electric guide rail 2 to cover the lower grinding turntable 17 on which the cruise wheel body 15 is placed. At the same time, the cylindrical cover body 3 also lowers the upper grinding turntable 8. When the cylindrical cover 3 drops to a certain position, the elastic corrugated telescopic sleeve 5 at the bottom contacts the support base 1, and the grinding space has been covered. Then, as the cylindrical cover 3 continues to drop, the elastic corrugated telescopic sleeve 5 begins to compress, and the downward pressure cross plate 9 provided at the same time drops synchronously, and during the dropping process, it contacts the linkage pressure ring 13, and the linkage pressure ring 13 drops relative to the support swivel 12. During this process, the linkage pressure ring 13 pushes the U-shaped top block 23 to move horizontally along the corresponding support guide rail 22 through the linkage rod 24, and the U-shaped top block 23 squeezes and pushes The two rotating clamping arms 19 corresponding to the top, when the two rotating clamping arms 19 are clamped, they rely on the runners 21 at the end to squeeze from both sides of the cruise ship body 15. Since the cruise ship body 15 is an annular disk, the cruise ship body 15 will move radially during the squeezing process, so that it is easy to contact the fixed friction wheel 18 to achieve tightening; then the electric telescopic rod 6 is controlled to extend, so that it drives the upper grinding turntable 8 to descend to the upper surface of the glass lens 16, and at the same time, the pressure value feedback from the pressure sensor is used to judge the contact situation between the upper grinding turntable 8 and the glass lens 16.

[0040] Finally, the first gear ring 10 is driven by the first driving gear 11 to cause the supporting rotating ring 12 to rotate. During this process, the two rotating clamping arms 19 corresponding to each set of clamping and tightening mechanisms clamp the cruise ship body 15 and revolve around the fixed friction wheel 18. Since the rotating clamping arms 19 are in contact with the cruise ship body 15 by means of the rotating wheels 21 at the ends, and the cruise ship body 15 is pressed against the fixed friction wheel 18, it can achieve rotation by friction during the revolution process. At the same time, the lower grinding turntable 17 is turned in the opposite direction to the supporting rotating ring 12 and starts to rotate. The upper grinding turntable 8 rotates synchronously in the opposite direction to the lower grinding turntable 17, thereby facilitating the grinding and polishing of the glass lens 16.

[0041] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
