DETAILED DESCRIPTION

[0040] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0041] The following describes an embodiment of the present invention based on its overall structure.

[0042] This embodiment discloses a multi-angle polishing device for precision optical glass. Figure 1-Figure 8 As shown, it includes a device body;

[0043] The device body includes a workbench 1, a longitudinal polisher 2, a transverse polisher 21, a positioning mechanism and a transmission mechanism;

[0044] The positioning mechanism includes an air cylinder 4 installed on the top of the workbench 1, a positioning plate 5 is installed on the top of the air cylinder 4, and an optical glass 3 is arranged on the top of the positioning plate 5. An air hole 51 connected to the air cylinder 4 is opened through the positioning plate 5. The positioning mechanism also includes a piston plate 6 slidably installed in the air cylinder 4.

[0045] When in use, the optical glass 3 is placed on the top of the positioning plate 5 so that the optical glass 3 is in contact with the top of the positioning plate 5. At this time, the piston plate 6 can be driven downward by the transmission mechanism, so that the gas between the positioning plate 5 and the optical glass 3 is drawn into the air guide cylinder 4 by the piston plate 6. At this time, the optical glass 3 is fixed on the top of the positioning plate 5, which makes it convenient for the user to operate the device to polish the optical glass 3.

[0046] Exemplarily, an air guide cavity 52 communicating with the air vent 51 is provided at the top of the positioning plate 5, and a positioning block 53 corresponding to the optical glass 3 is provided in the air guide cavity 52;

[0047] By setting the air guide cavity 52, there is gas between the positioning plate 5 and the optical glass 3. By setting the positioning block 53, the influence of the setting of the air guide cavity 52 on the shape stability of the optical glass 3 is reduced, ensuring that when the gas in the air guide cavity 52 starts to move into the air guide cylinder 4, the optical glass 3 will not be deformed or even damaged.

[0048] For example, see Figure 6 There are multiple groups of air holes 51 at the bottom of the positioning plate 5, and the multiple groups of air holes 51 are distributed in an X-shape, so that when the piston plate 6 moves downward, the multiple groups of air holes 51 can ensure that the gas in the air guide cavity 52 flows smoothly into the air guide cylinder 4, and further ensure that when the piston plate 6 moves downward, the positioning plate 5 can smoothly fix the optical glass 3.

[0049] For example, see Figure 3-Figure 5 , a plurality of positioning blocks 53 are installed at equal intervals in the air guide cavity 52. ​​Because the top of the positioning block 53 and the top of the positioning plate 5 are located at the same horizontal plane, the ends of the plurality of positioning blocks 53 will be in contact with the bottom of the optical glass 3, and the optical glass 3 will be supported, further improving the supporting effect on the bottom of the optical glass 3 and improving the stability of the optical glass 3 on the positioning plate 5. The spacing of the positioning blocks 53 is one-fourth of the width of the positioning blocks 53. At the same time, an air guide groove 54 is opened on the top of the positioning block 53, and the cross-section of the air guide groove 54 is designed in a "M" shape, and the top of the air guide groove 54 passes through the top of the positioning block 53, so that the gas between the air guide groove 54 and the optical glass 3 will also be evacuated as the piston plate 6 descends, further improving the adsorption and fixing effect on the optical glass 3;

[0050] It should be emphasized that, in the present embodiment, the installation position of the positioning block 53 is staggered with the air vent 51 , so that the installation of the positioning block 53 will not affect the use of the air vent 51 .

[0051] See also Figure 1-Figure 4, in this embodiment, the transmission mechanism includes a transmission frame 7 slidably mounted in the workbench 1, and one end of the transmission frame 7 is fixedly connected to the piston disk 6; when the transmission frame 7 starts to move, it will drive the piston disk 6 to move synchronously, so that the piston disk 6 can smoothly obtain the power to slide.

[0052] Furthermore, a transmission frame 73 corresponding to the longitudinal polisher 2 is installed at the end of the transmission frame 7 above the workbench 1, so that the transmission frame 7 and the transmission frame 73 move synchronously. At the same time, the transmission frame 73 is slidably connected to the workbench 1, so that the sliding of both the transmission frame 73 and the transmission frame 7 is restricted by the workbench 1, ensuring that the transmission frame 73 and the transmission frame 7 can only perform vertical lifting and lowering movements.

[0053] When using this device, the longitudinal polisher 2 starts to descend. During the descent of the longitudinal polisher 2, its outer wall contacts the top of the transmission frame 73. At this time, since the polishing disk of the longitudinal polisher 2 has not contacted the optical glass 3 yet and needs to continue descending, the longitudinal polisher 2 needs to continue descending. At this time, it will cause the transmission frame 73 to drive the transmission frame 7 to descend, resulting in the piston disk 6 obtaining the power to slide as the device starts.

[0054] Exemplarily, please refer to Figure 7 and Figure 8 , the cross-section of the transmission frame 7 is designed in an E shape, and the length of the end of the transmission frame 7 above the workbench 1 is greater than the lengths of the other two ends of the transmission frame 7, ensuring that the end of the transmission frame 7 protrudes from the top of the workbench 1. And a positioning rod 72 slidably connected to the transmission frame 7 is installed in the workbench 1. A limiting groove 71 corresponding to the positioning rod 72 is opened at the bottom of the transmission frame 7. When the transmission frame 7 slides, it is restricted by the limiting groove 71 and the positioning rod 72, further ensuring the stability of the transmission frame 7 during sliding.

[0055] In this embodiment, the transmission frame 73 is designed in a "C" shape, and the length of the transmission frame 73 is greater than the diameter of the optical glass 3, so that when the angle changes during the polishing process of the longitudinal polisher 2, the transmission frame 73 still adheres to the longitudinal polisher 2, ensuring the stability of the position of the transmission frame 73.

[0056] Please refer to Figure 1 One Figure 4 , in some other embodiments, the device body further includes an adjusting mechanism and a reset mechanism;

[0057] Among them, the adjusting mechanism includes a screw rod 10 threadedly installed at the bottom of the transmission frame 7. At the same time, the screw rod 10 is slidably connected to the workbench 1. When the screw rod 10 rotates, the position of the transmission frame 7 can be adjusted under the action of the screw principle, so that this device can adjust the adsorption force according to the actual situation of the optical glass 3, and further reduce the accident of damaging the optical glass 3 by suction.

[0058] At the same time, a turning handle 11 is installed at the bottom of the screw 10, and a limit plate 13 slidably connected to the bottom of the workbench 1 is installed on the outer wall of the turning handle 11. The setting of the limit plate 13 ensures the stability of the screw 10 during sliding and rotation. At the same time, the setting of the turning handle 11 makes it convenient for users to rotate the screw 10.

[0059] For example, see Figure 1-Figure 4 The reset mechanism includes a positioning seat 8 fixedly installed in the workbench 1, and the positioning seat 8 is slidably connected to the transmission frame 7 to ensure that the setting of the positioning seat 8 will not affect the transmission frame 7 driving the piston disc 6 to slide, and a first spring 9 connected to the piston disc 6 is fixedly installed on the top of the positioning seat 8. When the piston disc 6 moves downward, it will squeeze the first spring 9, so that the first spring 9 is in a compressed state. When the longitudinal polisher 2 starts to reset, the transmission frame 7 will gradually lose the resistance to reset. At this time, the first spring 9 will push the piston disc 6 to its original position.

[0060] For example, see Figure 1-Figure 4 The reset mechanism also includes a second spring 12 fixedly installed under the transmission frame 7, and the bottom of the second spring 12 is fixedly connected to the workbench 1. When the transmission frame 7 moves downward, the second spring 12 will be squeezed, so that when the pressure on the transmission frame 7 is released, the second spring 12 will cooperate with the first spring 9 to reset the transmission frame 7.

[0061] The working principle of the present invention is as follows: when the device is working, the optical glass 3 is first placed on the top of the positioning plate 5 so that it is closely attached to the positioning plate 5. After the device is started, the longitudinal polisher 2 begins to descend. During the descent, its outer wall first contacts the top of the transmission frame 73. Since the polishing plate of the longitudinal polisher 2 has not yet contacted the optical glass 3, it needs to continue to descend. This action will drive the transmission frame 73 to move downward. The descent of the transmission frame 73 will drive the transmission frame 7 to descend synchronously. At the same time, the descent of the transmission frame 7 will cause the piston plate 6 to slide downward in the air guide cylinder 4.

[0062] As the piston plate 6 moves downward, the gas between the positioning plate 5 and the optical glass 3 is quickly drawn into the air guide 4 through the air vent 51. As the gas is drawn out, negative pressure is formed between the positioning plate 5 and the optical glass 3. Under the action of the air pressure, the optical glass 3 is firmly adsorbed and fixed on the top of the positioning plate 5.

[0063] In this process, the setting of the air guide cavity 52 provides a buffer space for the flow of gas. The positioning block 53 supports the optical glass 3 on the one hand, and reduces the adverse effect of the setting of the air guide cavity 52 on the shape stability of the optical glass 3 on the other hand, ensuring that when the gas inside the air guide cavity 52 starts to move into the air guide cylinder 4, the optical glass 3 will not be deformed or even damaged. The design of the multiple groups of air holes 51 distributed in an X shape ensures that when the piston plate 6 moves downward, the gas inside the air guide cavity 52 can flow smoothly into the air guide cylinder 4, further ensuring that when the piston plate 6 moves downward, the positioning plate 5 can smoothly fix the optical glass 3;

[0064] When the screw 10 rotates, based on the principle of the screw, the position of the transmission frame 7 will change accordingly, so that the device can flexibly adjust the adsorption strength according to the actual situation of the optical glass 3, such as size, material, etc. In this way, the probability of the accident of damaging the optical glass 3 by adsorption can be further reduced;

[0065] After the polishing operation is completed, when the longitudinal polisher 2 starts to reset and rise, the pressure applied to the transmission frame 73 gradually decreases. At this time, the reset mechanism starts to work. When the piston disc 6 moves downward, the first spring 9 is in a compressed state. When the longitudinal polisher 2 is reset, the transmission frame 7 gradually loses the resistance to reset. The compressed first spring 9 will push the piston disc 6 back to its initial position. When the transmission frame 7 moves downward, the second spring 12 is squeezed. When the pressure on the transmission frame 7 is released, the second spring 12 will cooperate with the first spring 9 to quickly and stably reset the transmission frame 7 to prepare for the next polishing operation.

[0066] During the whole working process, the various mechanisms of the device cooperate and work together with each other, and through ingenious structural design and precise motion control, stable positioning of the optical glass 3 and efficient and precise polishing operations are achieved.
