Description

Technical Field

[0001] This invention relates to the field of gemstone workpiece processing equipment technology, specifically to an integrated equipment for fine grinding and polishing of gemstone workpieces. Background Technology

[0002] Gemstone workpieces refer to gemstone materials that have undergone processing such as cutting, grinding, and polishing to meet specific industrial or decorative needs. The processing of gemstone workpieces needs to take into account factors such as the hardness, brittleness, and optical properties of the gemstone to ensure its performance and durability in application. Among them, gemstone round bars are a type of gemstone workpiece. When processing gemstone round bars, it is necessary to use fine grinding and polishing equipment to grind and polish the two end faces of the gemstone round bars.

[0003] A sapphire substrate polishing apparatus as described in Chinese patent application number 201611265348.9 includes: a frame with a rotating shaft; a polishing table mounted on the frame and driven to rotate by the rotating shaft, the polishing table having a polishing surface for polishing a sapphire substrate located on the polishing table; and a ceramic disc located on the polishing surface, which moves the sapphire substrate relative to the polishing surface. The ceramic disc applies a greater pressure to the center of the sapphire substrate than to its edges. By utilizing the greater pressure applied to the center of the sapphire substrate than to its edges, the ceramic disc achieves a greater polishing force at the center than at the edges, resulting in a thinner center and a thicker middle section of the sapphire substrate, thereby giving the sapphire surface a certain degree of curvature.

[0004] When using fine grinding and polishing equipment to grind and polish the two end faces of a gemstone rod, the gemstone rod needs to be installed in a mounting frame, which is then installed above the polishing equipment. The sandpaper at the bottom of the polishing equipment rotates to polish the end faces of the gemstone rod. During fine grinding and polishing, sandpaper of different grits needs to be used to grind the end faces of the gemstone rod in sequence. It is inconvenient to change sandpaper of different grits during the grinding process, which affects the grinding efficiency. Summary of the Invention

[0040] Please see Figures 1-8This invention provides an integrated grinding and polishing device for gemstone workpiece processing, comprising: a base 1; a changing mechanism located at the top of the base 1, which uses a rotating frame 104 to change sandpaper of different grits; a conveying mechanism located at the bottom of the base 1, which uses a moving plate 3 to convey sandpaper of different grits; a grinding mechanism located on the changing mechanism, which uses grinding parts 403 to grind and polish the two end faces of the gemstone rod; and a driving mechanism located on one side of the top of the base 1, which drives the grinding mechanism to rotate via a transmission spur gear 505. The changing mechanism includes a rotating frame 104 and a rotating groove. 106, Rotating component 2, Second motor 201, Second gear 202, Several first mounting components 203, Third gear 205, First lead screw 206, Second lead screw 207, Fixing frame 208, Gear ring 209, Two moving slots 210 and a locking block 211, Rotating frame 104 is rotatably mounted on the top of base 1, Rotating slots 106 are opened at the centers of both ends of rotating frame 104, Rotating component 2 is rotatably mounted on the corresponding wall of rotating slot 106, Second motor 201 is fixedly mounted on the inner wall of rotating component 2, Second gear 202 is fixedly mounted on the output end of second motor 201, Several first mounting components 203 are fixedly mounted on the top of the inner wall of rotating component 2, First lead screw 206 and Second lead screw 207 are respectively fixedly mounted on the first mounting component 208, Second motor 201, Second gear 202, Several first mounting components 203, Third gear 205, First lead screw 206, Second lead screw 207, Fixing frame 208, Gear ring 209, Two moving slots 210 and Locking block 211, Rotating frame 104 is rotatably mounted on the top of base 1, Rotating slots 106 are opened at the centers of both ends of rotating frame 104, Rotating component 205 is rotatably mounted on the corresponding wall of rotating slot 106, Second motor 201 is fixedly mounted on the inner wall of rotating component 201, Second gear 202 is fixedly mounted on the output end of second motor 201, Several first mounting components 203 are fixedly mounted on the top of the inner wall of rotating component 2, First lead screw 206 and Second lead screw 207 are respectively fixedly mounted on the first mounting component 208, Second gear ring 209, At both ends of the three gears 205, the first lead screw 206 and the second lead screw 207 are rotatably mounted on the corresponding first mounting parts 203. A fixed bracket 208 is fixedly mounted to one end of the corresponding rotating part 2 by screws. A gear ring 209 is fixedly mounted to the outer wall of the corresponding fixed bracket 208. Two movable slots 210 are formed at one end of the fixed bracket 208. One end of the first lead screw 206 and the second lead screw 207 extends into the corresponding movable slots 210. A locking block 211 is slidably mounted on the wall of the corresponding movable slot 210. The locking block 211 is threadedly connected to the outer walls of the first lead screw 206 and the second lead screw 207 through its threaded holes. The third gear 205 meshes with the second gear 202. A replacement mechanism is provided to start the drive motor 103. The drive mechanism can rotate the rotating frame 104 at the top of the base 1 with the output end of the drive motor 103 as the center. The grinding mechanisms at both ends of the rotating frame 104 can rotate independently, and each grinding mechanism can be driven to rotate independently by the drive mechanism. When the grinding mechanism facing upward rotates to grind the end face of the gemstone rod, the grinding mechanism facing downward can be removed and replaced with different grit grinding mechanisms through the conveying mechanism below, making it more convenient to replace grinding mechanisms with different grits. The grinding parts 403 used for fine grinding or polishing are integrated through the replacement mechanism, increasing the degree of integration. Moreover, the grinding work of the gemstone rod is not affected when the grinding mechanism is replaced, thus improving the efficiency of fine grinding and polishing of the end face of the gemstone rod.

[0041] In some embodiments, see Figure 2 , Figure 5A drive motor 103 is fixedly installed on the top side of one side of the base 1. The output end of the drive motor 103 extends into the interior of the base 1. A rotating frame 104 is fixedly installed on the output end of the drive motor 103. The rotating frame 104 is annular. A second mounting component 204 is fixedly installed on one side of the first mounting component 203 by screws. A first lead screw 206 and a second lead screw 207 are respectively rotatably installed between the corresponding first mounting component 203 and second mounting component 204. By setting the first lead screw 206 and the second lead screw 207, the thread direction of the first lead screw 206 and the second lead screw 207 is... Conversely, the second motor 201 starts and drives the second gear 202 to rotate. The rotation of the second gear 202 drives the third gear 205 to rotate. The rotation of the third gear 205 drives the first lead screw 206 and the second lead screw 207 fixed at both ends to rotate. The rotation of the first lead screw 206 and the second lead screw 207 drives the locking block 211 on them to move synchronously in opposite directions in the moving groove 210. When the locking block 211 moves, the moving groove 210 can limit the locking block 211, which can fix the mounting plate 4 on the corresponding fixing bracket 208 or remove the fixing of the mounting plate 4.

[0042] In this example, the first lead screw 206 and the second lead screw 207 can be installed and limited by setting the first mounting component 203 and the second mounting component 204.

[0043] In some embodiments, see Figure 6 Both the rotating frame 104 and the outer wall of the base 1 have several positioning holes 105 on both sides. A second cylinder 6 is fixedly installed at the positioning hole 105 on the outer wall of the base 1. A fixing post 601 is fixedly installed at the output end of the second cylinder 6. The fixing post 601 engages with the corresponding positioning hole 105 on the rotating frame 104. By setting the second cylinder 6, the second cylinder 6 starts and drives the fixing post 601 to move. After the rotating frame 104 has rotated and flipped, the fixing post 601 is inserted into the corresponding positioning hole 105, which can better fix the rotating frame 104.

[0044] In some embodiments, see Figure 6 Airbags 602 are fixedly installed at both ends of the rotating frame 104. An air supply pipe 603 is fixedly installed on one side of the airbag 602, and one end of the air supply pipe 603 extends to the outside of the rotating frame 104. One end of the air supply pipe 603 is connected to an electric pressure relief valve in the prior art, and the other end of the electric pressure relief valve is connected to an air pump through a pipe. The air pump inflates the airbag 602, causing the airbag 602 to expand and increase the resistance to the rotation of the fixed frame 208. When changing the grinding mechanism, the fixed frame 208 at the corresponding end can be fixed, which facilitates the replacement of the grinding mechanism.

[0045] In this example, the air is released by the electric pressure relief valve, causing the airbag 602 to contract, so that the fixed frame 208 at the corresponding position can rotate smoothly.

[0046] In some embodiments, see Figure 1 , Figure 3 The conveying mechanism includes a movable plate 3, a rack 301, several mounting cylinders 302, several first cylinders 303, a movable disk 304, a third motor 305, and a positioning column 306. The movable plate 3 is slidably mounted on the bottom of the base 1 via a slide rail, with both ends extending to the outside of the base 1. The rack 301 is fixedly mounted on one side of the movable plate 3. Several mounting cylinders 302 are fixedly mounted on the top of the movable plate 3 with screws. Several first cylinders 303 are fixedly mounted on the bottom of the inner wall of the mounting cylinders 302. The movable disk 304 is fixedly mounted on the output end of the first cylinders 303. The third motor 305 is fixedly mounted on the bottom of the movable disk 304, with the output end of the third motor 305 extending to the top of the movable disk 304. The positioning column 306 is fixedly mounted on the third motor 305. At the output end, a moving motor 101 is fixedly installed on the bottom side of one side of the base 1. A first gear 102 is fixedly installed at the output end of the moving motor 101. A notch is provided at the bottom side of one side of the base 1. One side of the first gear 102 extends through the notch into the interior of the base 1. The first gear 102 meshes with a rack 301 on one side of the moving plate 3. Several moving wheels 307 are fixedly installed at the bottom end of the moving plate 3. When the moving motor 101 is started, it drives the first gear 102 to rotate. The rotation of the first gear 102 drives the moving plate 3 to move at the bottom of the base 1 through the rack 301 on one side of the moving plate 3. Several mounting cylinders 302 are provided on the moving plate 3. One mounting cylinder 302 can be used to collect the replaced grinding mechanism. The other mounting cylinders 302 contain the grinding mechanism that needs to be replaced.

[0047] In this example, each mounting cylinder 302, which holds the grinding mechanism that needs to be replaced, can hold two grinding mechanisms with different grit sizes. The first cylinder 303 pushes the moving disk 304 upward, causing the grinding mechanism on it to move upward and be installed on the corresponding fixed frame 208, which facilitates the transportation of the grinding mechanism.

[0048] In this example, the grinding mechanism in the mounting cylinder 302 can be adjusted by the operator.

[0049] For further details, please refer to the following: Figure 4The drive mechanism includes a first mounting plate 5, a first electric push rod 501, a moving frame 502, a fourth motor 503, a first turntable 504, a transmission spur gear 505, a second turntable 506, and a transmission belt 507. The first mounting plate 5 is fixedly mounted on the top of one side of the base 1. The first electric push rod 501 is fixedly mounted on the top of the first mounting plate 5. The moving frame 502 is slidably mounted in the sliding groove at the top of the first mounting plate 5 via a slider at the bottom. The moving frame 502 is fixedly mounted on the output end of the first electric push rod 501. The fourth motor 503 is fixedly mounted on the top of the moving frame 502, and the output end of the fourth motor 503 extends into the interior of the moving frame 502. The first turntable 504 is fixedly mounted on the top of the base 1. The first turntable 504 is fixedly installed at the output end of the fourth motor 503. The second turntable 506 is fixedly installed at one end of the transmission spur gear 505. The transmission spur gear 505 is rotatably installed on the inner wall of the movable frame 502, and one side of the transmission spur gear 505 extends to the outside of the movable frame 502. The outer walls of the first turntable 504 and the second turntable 506 are equipped with transmission belts 507, with both ends of the transmission belts 507 respectively installed on the outer walls of the first turntable 504 and the second turntable 506. When the fourth motor 503 is started, it can drive the first turntable 504 to rotate. The first turntable 504 drives the second turntable 506 to rotate through the transmission belts 507, thereby driving the transmission spur gear 505 to rotate, which can drive the gear ring 209 to rotate.

[0050] In this example, a water pump can be installed on one side of the first mounting plate 5. One end of the water pump is connected to a water tank in the prior art through a pipe, and a corrugated pipe is installed on the other end of the water pump. A nozzle is installed on one end of the corrugated pipe, and the nozzle faces the grinding part 403. Water is sprayed onto the grinding part 403 when grinding the gemstone round bar.

[0051] Furthermore, the grinding mechanism includes a mounting plate 4, a slot 401, a positioning groove 402, and a grinding component 403. Several slots 401 are formed at one end of the mounting plate 4, and the positioning groove 402 is formed at the center of one end of the mounting plate 4. The grinding component 403 is glued and fixed to one end of the mounting plate 4. The slots 401 engage with the corresponding slots 211, and the positioning grooves 402 engage with the corresponding positioning posts 306. The grinding component 403 can be sandpaper. By setting the positioning groove 402, the mounting plate 4 can be inserted into the positioning post 306 in the mounting cylinder 302. The positioning post 306 is rotated by the third motor 305, causing the mounting plate 4 to rotate, which facilitates the adjustment of the angle of the grinding mechanism when installing it.

[0052] like Figure 8As shown, a second mounting plate 7 is fixedly installed on one side of the top of the base 1. A second electric push rod 701 is fixedly installed on the top of the second mounting plate 7. A mounting bracket 702 is fixedly installed on the output end of the second electric push rod 701. The mounting bracket 702 is slidably installed in the slot at the top of the second mounting plate 7 via a slider at the bottom. A frame body 7021 is installed on the mounting bracket 702. Several mounting seats 703 are fixedly installed on the frame body 7021. Several mounting holes are opened at one end of the mounting seats 703. Gaskets 704 are fixedly installed on the inner wall of the mounting holes. Mounting frames 705 are fixedly installed on both sides of the mounting bracket 702. A rotating motor 706 is fixedly installed on the inner wall of the mounting frame 705. The output end of the rotating motor 706 extends to the outside of the mounting frame 705. A pressing component 707 is fixedly installed on the output end of the rotating motor 706. Two fixing ears are fixedly installed on the outer wall of the top mounting seat 703 on the frame 7021. The pressing component 707 engages with the corresponding fixing ears. By setting the mounting seat 703, the gemstone rod is inserted into the gasket 704. The gasket 704 can be a rubber gasket 704. The gasket 704 increases the friction of the outer wall of the gemstone rod. The gemstone rod is installed by setting the mounting seat 703.

[0053] In this example, when the rotating frame 104 rotates, the first electric push rod 501 and the second electric push rod 701 are activated to drive the first mounting plate 5 and the second mounting plate 7 to move backward away from the top of the rotating frame 104.

[0054] In this example, the moving motor 101, drive motor 103, second motor 201, third motor 305, fourth motor 503, and rotating motor 706 can be servo motors.

[0055] The working process and principle of this invention are as follows: When the gemstone rod is finely ground and polished, the gemstone rod is inserted into the shim 704. The rotating motor 706 starts and drives the pressing part 707 to rotate, pressing the fixing ear and pressing down on the mounting base 703, so that the end face of the gemstone rod is pressed against the end face of the grinding part 403. The fourth motor 503 starts and drives the first turntable 504 to rotate. The first turntable 504 drives the second turntable 506 to rotate through the transmission belt 507, thereby driving the transmission spur gear 505 to rotate, causing the gear ring 209 to rotate, thereby causing the grinding mechanism to rotate, and finely grinding and polishing the end face of the gemstone rod.
