Description

Technical Field

[0001] The present invention relates to a grinding device, in particular to an optical glass grinding device applied to the technical field of optical glass processing. Background Art

[0002] Optical glass refers to glass that can change the direction of light propagation and the relative spectral distribution of ultraviolet, visible or infrared light. Since the grinding and polishing process of optical glass is very complicated, for different grinding and polishing surfaces, the rotation speed, pressure, grinding disc size and material will affect the control accuracy and stability, so the control is very complicated, and the operation of the grinding and polishing equipment is relatively complicated, and the grinding and polishing work is cumbersome, which increases the production cost of optical glass.

[0003] The specification of Chinese patent CN201710800803.9 discloses "A method for forming the surface of optical glass". This invention uses the same machine tool to perform three grindings, as well as one rough polishing and one fine polishing. Under the premise of optical glass surface processing accuracy, the surface forming time and operation complexity are greatly reduced. The entire grinding and polishing process only requires the replacement of the corresponding polishing disc and polishing liquid, without the need to replace the machine tool and fixture, etc., which reduces the time for frequent tool replacement, simplifies the process flow and improves processing efficiency.

[0004] Existing optical glass needs to be ground multiple times during the processing process. For example, in the above invention, the optical glass is ground three times. For the different degrees of grinding of the optical glass, the grinding tools and grinding fluids required for grinding correspond to each other, that is, coarse grinding tools correspond to coarse grinding fluids, and fine grinding tools correspond to fine grinding fluids. The grinding fluid needs to be recovered after use, but the existing grinding equipment cannot distinguish the recovery of the grinding fluid, which easily causes the mixing of grinding fluids of different qualities, affecting the recovery and use of the grinding fluid. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the existing grinding equipment cannot distinguish the recovery of grinding liquid, which easily causes the mixing of grinding liquids of different qualities, affecting the recovery and use of the grinding liquid.

[0006] In order to solve the above problems, the present invention provides an optical glass grinding device, comprising a machine body, a ring disc and a grinding drive head are respectively fixedly connected to the bottom and the top of the machine body, a lifting processing module is rotatably connected to the middle of the ring disc, a workpiece is placed in the middle of the lifting processing module, a plurality of grinding heads are rotatably connected to the bottom of the grinding drive head, the grinding heads correspond to the surface of the workpiece, and grinding liquid tubes are respectively fixedly connected to the outside of the top of the grinding drive head, and the bottom ends of the grinding liquid tubes face the corresponding lifting processing modules;

[0007] A plurality of grinding liquid tanks are placed on the outer side of the bottom of the machine body, a liquid delivery pipe is fixedly connected between the grinding liquid tank and the grinding liquid pipe, and each grinding liquid tank corresponds to a grinding head, a return liquid pipe is fixedly connected between the grinding liquid tank and the bottom of the circle disk, a barrel cover is rotatably connected to the top of the circle disk, a connecting nozzle is fixedly connected to the bottom of the barrel cover, the connecting nozzle is plugged into the upper opening of the return liquid pipe, a sealing plug is movably connected inside the upper opening of the return liquid pipe, and the upper surface of the sealing plug is in contact with the connecting nozzle.

[0008] In the above-mentioned optical glass grinding equipment, different qualities of grinding heads on the grinding drive head are used to perform progressive grinding processing on the optical glass, which effectively improves the processing quality of the optical glass. When switching grinding heads of different qualities, the barrel cover is rotated synchronously, and the recovery of grinding liquids of different qualities is achieved by switching and plugging the connecting nozzle and the return liquid pipe, which effectively avoids the mixing of grinding liquids of different qualities and facilitates the recovery and reuse of the grinding liquid.

[0009] As a further improvement of the present application, the grinding head is made of ceramic material, and the roughness of multiple grinding heads is arranged in a sequentially decreasing manner, which effectively improves the wear resistance of the grinding head and facilitates the use of grinding heads with different roughness qualities to perform phased fine grinding of optical glass, thereby effectively improving the grinding effect of optical glass.

[0010] As a further improvement of the present application, the top outer ring of the lifting processing module is fixedly connected with a guide skirt ring, the guide skirt ring is in contact with the bottom of the inner ring of the barrel cover, and the guide skirt ring is made of elastic rubber material. The guide skirt ring is utilized to improve the waterproof effect between the barrel cover and the lifting processing module, thereby effectively avoiding liquid leakage.

[0011] As a further improvement of the present application, a lifting bracket is movably connected to the middle part of the machine body, a gear ring is fixedly connected to the bottom of the outer ring of the barrel cover, and a gear is rotatably connected to the rear part of the inner ring of the lifting bracket. The gear is meshed with the gear ring, and the barrel cover is rotated by the meshing of the gear and the gear ring, thereby realizing the switching connection of the connecting nozzle between the return liquid pipes.

[0012] As another improvement of the present application, a top spring is fixedly connected to the bottom of the sealing plug, and the sealing plug is made of rubber material. The top spring is utilized to push the sealing plug to automatically rise, thereby automatically sealing the return liquid pipe to which the connecting nozzle is not plugged, thereby effectively preventing liquid from entering the non-designated return liquid pipe during the rotation and switching of the barrel cover.

[0013] As another improvement supplement to the present application, a cleaning pipe is fixedly connected to the outside of the grinding liquid tube in parallel, and the bottom of the cleaning pipe is fixedly connected to a water spray pipe. The cleaning pipe cooperates with the water spray pipe to wash the inside of the barrel cover with water to flush away traces of the previous grinding liquid use, prepare for the next use of the grinding liquid, and effectively avoid the residual grinding liquid affecting the subsequent recovery of the grinding liquid.

[0014] As another improvement supplement of the present application, the water nozzle is arranged in a semicircular shape, and spray holes are provided on the outer arc surface and the inner arc surface of the water nozzle. The semicircular water nozzle increases the cleaning area and effectively improves the water washing effect of the spray holes on the inner wall of the cylinder cover, the lifting processing module and the processed parts.

[0015] As another improvement of the present application, a water receiving trough is placed on the outer side of the bottom of the machine body, a wastewater pipe is fixedly connected to the bottom of the ring plate, a filter pump is fixedly connected to the inside of the water receiving trough, a water supply pipe is connected between the cleaning pipe and the output end of the filter pump, and the water receiving trough uses the filter pump and the water supply pipe to transport cleaning water to the cleaning pipe, and the subsequent water is recovered by the wastewater pipe, effectively improving the use of cleaning water.

[0016] As another improvement supplement of the present application, the end of the water supply pipe away from the filter pump is Y-shaped and divided into two end pipes, which are respectively plugged into the top of the grinding liquid tube and the cleaning tube. The grinding liquid tube is plugged into the end tube to achieve water flushing of the inside of the grinding liquid tube, effectively preventing residual grinding liquid in the grinding liquid tube from affecting subsequent use of the grinding liquid.

[0017] In summary, the present invention utilizes grinding heads of different qualities on the grinding drive head to perform progressive grinding processing on optical glass, thereby realizing the gradual forming of the optical glass mirror surface, effectively improving the grinding accuracy and efficiency of the optical glass, and effectively reducing the processing cost of the optical glass. When switching grinding heads of different qualities, the barrel cover is rotated synchronously, and different grinding liquid recovery pipeline structures are formed by switching and plugging the connecting nozzle and the return liquid pipe. During the switching and rotation of the barrel cover, the non-designated return liquid pipe is closed by the sealing plug, which effectively prevents the grinding liquid from entering the non-designated return liquid pipe, thereby facilitating the recovery of grinding liquids of different qualities. At the same time, it effectively avoids the mixing of grinding liquids of different qualities, thereby facilitating the recovery and reuse of the grinding liquid. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0030] The first implementation method:

[0031] Figures 1 to 4 The figure shows an optical glass grinding device, comprising a body 1, wherein a ring disc 2 and a grinding drive head 3 are fixedly connected to the bottom and the top of the body 1, respectively; a lifting processing module 201 is rotatably connected to the middle of the ring disc 2, a workpiece 202 is placed in the middle of the lifting processing module 201, a plurality of grinding heads 301 are rotatably connected to the bottom of the grinding drive head 3, the grinding heads 301 correspond to the surfaces of the workpiece 202, grinding liquid tubes 302 are fixedly connected to the outside of the top of the grinding drive head 3, the bottom ends of the grinding liquid tubes 302 face the corresponding lifting processing modules 201, and the grinding heads 301 are made of ceramic material. The roughness of the multiple grinding heads 301 is set to decrease in sequence, which effectively improves the wear resistance of the grinding heads 301, and facilitates the use of grinding heads 301 with different roughness qualities to perform staged fine grinding on the optical glass, effectively improving the grinding effect of the optical glass. The top outer ring of the lifting processing module 201 is fixedly connected with a guide skirt ring 203, which contacts the bottom of the inner ring of the barrel cover 403, and the guide skirt ring 203 is made of elastic rubber material. The guide skirt ring 203 is used to improve the waterproof effect between the barrel cover 403 and the lifting processing module 201, effectively avoiding leakage.

[0032] When performing grinding processing on optical glass, the workpiece 202 to be processed is fixedly installed in the middle of the lifting processing module 201, and then the grinding drive head 3 descends. The workpiece 202 is firstly roughly ground using the coarse grinding head 301. During the grinding process, the grinding liquid tube 302 adds coarse grinding liquid between the grinding head 301 and the workpiece 202. When the lifting processing module 201 is lifted and lowered, the guide skirt ring 203 is used to improve the waterproof effect between the barrel cover 403 and the lifting processing module 201, that is, the skirt edge of the guide skirt ring 203 performs an ups and downs movement, and always maintains a covering contact with the bottom of the inner circle of the barrel cover 403, effectively avoiding leakage.

[0033] Figures 1 to 7 As shown, a plurality of grinding liquid tanks 4 are placed on the outer side of the bottom of the machine body 1, a liquid delivery pipe 401 is fixedly connected between the grinding liquid tank 4 and the grinding liquid tube 302, and each grinding liquid tank 4 corresponds to the grinding head 301, a return liquid pipe 402 is fixedly connected between the grinding liquid tank 4 and the bottom of the circle plate 2, a barrel cover 403 is rotatably connected to the top of the circle plate 2, a connecting nozzle 404 is fixedly connected to the bottom of the barrel cover 403, the connecting nozzle 404 is plugged into the upper opening of the return liquid pipe 402, a sealing plug 405 is movably connected inside the upper opening of the return liquid pipe 402, and the upper surface of the sealing plug 405 is in contact with the connecting nozzle 404, a top spring 406 is fixedly connected to the bottom of the sealing plug 405, and the sealing plug 40 5 is made of rubber material, and the sealing plug 405 is automatically raised by the upper spring 406 to realize automatic blocking of the return pipe 402 that is not plugged with the connecting nozzle 404, effectively preventing the liquid from entering the non-designated return pipe 402 during the rotation and switching process of the barrel cover 403. The middle part of the body 1 is movably connected with the lifting bracket 101, and the outer ring bottom of the barrel cover 403 is fixedly connected with the gear ring 102. The rear part of the inner ring of the lifting bracket 101 is rotatably connected with the gear 103, and the gear 103 is meshed with the gear ring 102. The barrel cover 403 is rotated by the way that the gear 103 is meshed with the gear ring 102, so as to realize the switching connection between the connecting nozzle 404 and the return pipe 402;

[0034] After the coarse grinding of the optical glass is completed, when the grinding drive head 3 switches to the finer grinding head 301, the lifting processing module 201 first moves downward, driving the workpiece 202 to move away from the grinding head 301, and at the same time allowing the connecting nozzle 404 at the bottom of the barrel cover 403 to be pulled out from the return liquid pipe 402, and then the barrel cover 403 rotates to drive the connecting nozzle 404 to rotate and switch to another return liquid pipe 402, and then the lifting processing module 201 rises and recovers to realize the grinding of the workpiece 202 and the newly switched grinding head 301, and the connecting nozzle 404 is inserted into the return liquid pipe 402, pressing the sealing plug 405 to descend, so as to realize the connection between the connecting nozzle 404 and the return liquid pipe 402, and the remaining return liquid pipes 402 continue to keep the sealing plug 405 closed, effectively preventing liquid from entering the non-designated return liquid pipe 402 during the rotation and switching of the barrel cover 403.

[0035] The second implementation method:

[0036] Compared with the first embodiment, this embodiment mainly adds a cleaning pipe 5. The specific newly added structure is as follows, and the remaining structures are consistent with the first embodiment.

[0037] Figures 7 and 8 As shown, the outside of the grinding liquid tube 302 is parallelly fixedly connected with a cleaning tube 5, and the bottom of the cleaning tube 5 is fixedly connected to a water spray pipe 501. The cleaning tube 5 cooperates with the water spray pipe 501 to wash the inside of the barrel cover 403 with water, flushing the traces of the previous use of the grinding liquid, preparing for the next use of the grinding liquid, and effectively avoiding the residual grinding liquid from affecting the subsequent recovery of the grinding liquid. The water spray pipe 501 is arranged in a semicircular shape, and the outer arc surface and the inner arc surface of the water spray pipe 501 are both provided with spray holes 502. The semicircular water spray pipe 501 increases the cleaning area, effectively improving the spray hole 5 02 For the washing effect of the inner wall of the barrel cover 403, the lifting processing module 201 and the workpiece 202, a water receiving tank 503 is placed on the outer side of the bottom of the body 1, a waste water pipe 504 is fixedly connected to the bottom of the ring plate 2, a filter pump 505 is fixedly connected inside the water receiving tank 503, a water delivery pipe 506 is connected between the cleaning pipe 5 and the output end of the filter pump 505, and the water receiving tank 503 uses the filter pump 505 to cooperate with the water delivery pipe 506 to transport cleaning water to the cleaning pipe 5, and the subsequent water is recovered by the waste water pipe 504, which effectively improves the use of cleaning water;

[0038] During the rotation and switching of the barrel cover 403, the water receiving tank 503 uses the filter pump 505 and the water pipe 506 to transport cleaning water to the cleaning pipe 5. The cleaning pipe 5 cooperates with the water nozzle 501 to wash the inside of the barrel cover 403 with water to rinse out the traces of the previous grinding liquid use, prepare for the next use of the grinding liquid, and effectively avoid the residual grinding liquid affecting the subsequent recovery of the grinding liquid. During the washing process of the inside of the barrel cover 403, the lifting and lowering processing module 201 is on the descending turntable, and the cleaning water in the barrel cover 403 is directly discharged downward from the connecting nozzle 404, and the discharged rinsing water is directly on the circle plate 2. At this time, only the waste water pipe 504 on the circle plate 2 is in an open state, which is convenient for the direct recovery of the rinsing water and effectively improves the use of cleaning water.

[0039] Figures 8 to 9 As shown, one end of the water delivery pipe 506 away from the filter pump 505 is Y-shaped and is divided into two end pipes 507, and the two end pipes 507 are respectively plugged with the top of the grinding liquid pipe 302 and the cleaning pipe 5, and the grinding liquid pipe 302 is plugged into the end pipe 507 to achieve water flushing of the inside of the grinding liquid pipe 302, effectively preventing the residual grinding liquid in the grinding liquid pipe 302 from affecting the subsequent use of the grinding liquid;

[0040] By setting the water supply pipe 506 in a Y shape and connecting the two end pipes 507 to the top of the grinding liquid tube 302 and the cleaning tube 5 respectively, the water supply pipe 506 can simultaneously supply water to the cleaning tube 5 and the grinding liquid tube 302, so that the water can flush the inside of the grinding liquid tube 302, effectively preventing the residual grinding liquid in the grinding liquid tube 302 from affecting the subsequent use of the grinding liquid.

[0041] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
