Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and in particular to a double-sided grinding device for processing high-precision optical components. Background Technology

[0002] Double-sided grinding machines for optical components are mainly used for double-sided grinding of crystals or other mechanical parts with parallel surfaces, especially for processing thin and brittle materials. They are suitable for grinding and polishing various materials such as mechanical seal rings, ceramic sheets, cylinder piston rings, oil pump blade bearing end faces, and metal materials including silicon, germanium, quartz crystals, graphite, sapphire, optical crystals, glass, lithium niobate, cemented carbide, stainless steel, and powder metallurgy. Existing double-sided grinding machines leave residual powder on the bearings and cutter head after grinding. With prolonged use, if not cleaned promptly, this residual powder will cause wear and tear on the cutter head, which is a consumable part.

[0003] Chinese utility model patent CN221676847U discloses a double-sided grinding device for optical element processing, including an operating machine, a lower grinding disc, and a cleaning device. The lower grinding disc is fixedly connected to the upper end of the operating machine, and the cleaning device is fixedly connected to the outer side of the lower grinding disc. The cleaning device includes a toothed ring with a groove on its upper end. A hollow ring is slidably connected to the upper end of the groove, and a water outlet pipe is fixedly connected to the inner side of the hollow ring. A support frame is fixedly connected to the upper end of the operating machine, and a motor is fixedly connected to the center of the upper end of the support frame. A transmission device is fixedly connected to one end of the motor spindle. The transmission device includes a connecting shaft, and an empty chamber is slidably connected to the outer side of the connecting shaft. In this utility model, by setting an empty chamber piston, the up and down movement of the piston can be controlled to realize the dripping of protective glue and the cleaning of the workpiece. The water outlet pipe can effectively clean the workpiece and the grinding device after grinding, and at the same time, it can perform comprehensive cleaning of the workpiece, thereby improving product quality.

[0004] Regarding the aforementioned technologies, the inventors believe the following drawbacks exist: The device cleans the cutter head using a cleaning unit mounted on the manipulator. Upon completion of processing, the operator must reset the connecting shaft to automatically spray water outwards. In actual use, the cleaning unit can only passively spray water. If a single cleaning cycle cannot completely remove impurities from the cutter head, residual impurities on a single disc can still easily cause wear and tear, resulting in a poor user experience. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a double-sided grinding device for high-precision optical component processing.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a double-sided grinding device for high-precision optical element processing, comprising an operating machine, a lower grinding disc disposed on the operating machine, a support frame disposed on the operating machine, and a transmission device disposed on the support frame. A first support rod is fixed on the upper surface of the operating machine, and a second support rod is fixed on the upper surface of the operating machine. A cleaning component for cleaning the lower grinding disc is disposed on the first support rod.

[0007] By adopting the above technical solution, when workers need to grind optical components, they place the optical components on the lower grinding wheel and activate the transmission device. This moves the upper grinding wheel on the transmission device downwards and presses against the optical component, allowing the upper and lower grinding wheels to cooperate and grind the optical component. After grinding, the transmission device needs to be reset. A large amount of impurities may remain on the lower grinding wheel. At this point, the worker connects the connecting rod to the second support rod and activates the cleaning device. This allows the cleaning device to continuously clean the lower grinding wheel, reducing the difficulty of cleaning it.

[0008] Furthermore, the cleaning assembly includes a rotating plate slidably disposed on the first support rod, a connecting rod slidably disposed on the rotating plate, a cleaning device disposed on the rotating plate for cleaning the lower grinding disc, and a limiting device disposed on the second support rod for limiting the connecting rod.

[0009] By adopting the above technical solution, when workers need to clean the lower grinding disc, they need to rotate the rotating plate towards the second support rod, which will gradually bring the connecting rod closer and eventually align it with the second support rod. At this time, the limiting device automatically limits the connecting rod, thereby keeping the connecting rod and the second support rod stable. Furthermore, workers only need to turn on the cleaning device to continuously clean the lower grinding disc.

[0010] Furthermore, the cleaning device includes a water tank fixed on the rotating plate, a water pump connected to the water tank, a water outlet pipe connected to the water pump, and a nozzle connected to the end of the water outlet pipe. The water outlet pipe passes through the rotating plate and is slidably connected.

[0011] By adopting the above technical solution, when workers need to clean the lower grinding disc, they only need to turn on the water pump, which will continuously draw water from the water storage tank and discharge the water through the outlet pipe and nozzle, thereby continuously cleaning the lower grinding disc and reducing the difficulty for workers to clean the lower grinding disc.

[0012] Furthermore, a limiting groove is formed on the upper surface of the second support rod, and the limiting device includes a limiting rod that is slidably disposed in the limiting groove and a compression spring fixed to the bottom surface of the limiting rod. The other end of the compression spring is fixed to the inner bottom wall of the limiting groove, and a limiting hole that matches the limiting rod is formed on the bottom surface of the connecting rod.

[0013] Furthermore, an inclined surface is provided on the edge where the upper surface of the limiting rod intersects with its side wall.

[0014] By adopting the above technical solution, when workers need to clean the lower grinding disc, they need to rotate the rotating plate towards the second support rod. This causes the connecting rod to press against the inclined surface, thereby allowing the limiting rod to move completely into the limiting groove. Subsequently, when the connecting rod and the second support rod are aligned, the limiting groove and the limiting hole are aligned, allowing the limiting rod to connect with the limiting hole under the action of the compression spring, thus blocking the connecting rod. Furthermore, workers can adjust the height of the nozzle simply by sliding the rotating plate downwards, thereby improving the cleaning effect of the nozzle.

[0015] Furthermore, a drive groove is provided through the inner wall of the limiting groove, and a drive rod is slidably disposed in the drive groove, the drive rod being fixed to the limiting rod.

[0016] By adopting the above technical solution, after the worker finishes cleaning, in order to reduce the interference of the rotating plate on the grinding work, the worker needs to slide the drive rod downwards, which will cause the limit rod to move downwards with the drive rod, thereby separating the limit rod from the limit hole. At this time, the worker only needs to rotate the rotating plate in the opposite direction to reset the rotating plate.

[0017] Furthermore, a baffle for blocking the connecting rod is fixed on the side wall of the second support rod.

[0018] Furthermore, a stop block is fixed on the inner wall of the baffle, a fixing hole matching the stop block is opened on the side wall of the connecting rod, and a through groove for the baffle to pass through is opened on the bottom surface of the rotating plate.

[0019] By adopting the above technical solution, when the operator rotates the rotating plate towards the second support rod, the baffle blocks the connecting rod, thereby reducing the difficulty for the operator to align the connecting rod with the second support rod. When the connecting rod is aligned with the second support rod, the baffle connects with the fixing hole, thereby limiting the connecting rod in the vertical direction. This reduces the probability of the connecting rod separating from the second support rod when the operator moves the rotating plate upwards, thus improving the operator's user experience.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. In this application, when an operator needs to grind an optical element, the operator places the optical element on the lower grinding wheel and activates the transmission device. This causes the upper grinding wheel on the transmission device to move downwards and press against the optical element, allowing the upper and lower grinding wheels to cooperate and grind the optical element. After grinding, the operator needs to reset the transmission device, as a large amount of impurities may remain on the lower grinding wheel. At this point, the operator connects the connecting rod to the second support rod and activates the cleaning device, which continuously cleans the lower grinding wheel, thus reducing the difficulty of cleaning it.

[0022] 2. In this application, when the worker needs to clean the lower grinding disc, the worker needs to rotate the rotating plate towards the second support rod, so that the connecting rod gradually approaches and eventually aligns with the second support rod. At this time, the limiting device automatically limits the connecting rod, thereby keeping the connecting rod and the second support rod stable. Furthermore, the worker only needs to turn on the cleaning device to continuously clean the lower grinding disc;

[0023] 3. In this application, when the worker needs to clean the lower grinding disc, the worker needs to rotate the rotating plate towards the second support rod, which will cause the connecting rod to press against the inclined surface, thereby allowing the limiting rod to move completely into the limiting groove. Subsequently, when the connecting rod and the second support rod are aligned, the limiting groove and the limiting hole are aligned, so that the limiting rod connects with the limiting hole under the action of the compression spring, thereby blocking the connecting rod. Furthermore, the worker only needs to slide the rotating plate downwards to adjust the height of the nozzle, thereby improving the cleaning effect of the nozzle. Attached Figure Description

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] like Figure 1-4 As shown in the illustration, this application discloses a double-sided grinding apparatus for high-precision optical component processing, including a manipulator 1, a lower grinding disc 11, a support frame 2, a transmission device 21, a first support rod 3, a second support rod 31, a cleaning assembly 4, a drive rod 71, a baffle 8, and a stop block 81. The lower grinding disc 11 is mounted on the manipulator 1, the support frame 2 is mounted on the manipulator 1, and the transmission device 21 is mounted on the support frame 2. The first support rod 3 has a round rod structure and is fixed to the upper surface of the manipulator 1. The second support rod 31 has a round rod structure and is fixed to the upper surface of the manipulator 1.

[0031] The cleaning assembly 4 is mounted on the first support rod 3 and is used to clean the lower grinding disc 11. The cleaning assembly 4 includes a rotating plate 41, a connecting rod 42, a cleaning device 5, and a limiting device 6. The rotating plate 41 is a plate-shaped structure and is slidably mounted on the first support rod 3. The connecting rod 42 is a round rod-shaped structure and is slidably mounted on the rotating plate 41.

[0032] When the worker needs to clean the lower grinding disc 11, the worker needs to rotate the rotating plate 41 towards the second support rod 31, so that the connecting rod 42 gradually approaches and eventually aligns with the second support rod 31. At this time, the limiting device 6 automatically limits the connecting rod 42, thereby keeping the connecting rod 42 and the second support rod 31 stable. Furthermore, the worker only needs to turn on the cleaning device 5 to continuously clean the lower grinding disc 11.

[0033] A cleaning device 5 is mounted on a rotating plate 41 and is used to clean the lower grinding disc 11. The cleaning device 5 includes a water storage tank 51, a water pump 52, a water outlet pipe 53, and a nozzle 54. The water storage tank 51 is fixed on the rotating plate 41 and is used to store water. The water pump 52 is connected to the water storage tank 51. The water outlet pipe 53 is a circular pipe structure and is connected to the water pump 52. The nozzle 54 is connected to the end of the water outlet pipe 53, and the water outlet pipe 53 passes through the rotating plate 41 and is slidably connected.

[0034] When the staff needs to clean the lower grinding disc 11, they need to turn on the water pump 52, which will continuously draw water from the water storage tank 51 and discharge the water through the water outlet pipe 53 and the nozzle 54, thereby continuously cleaning the lower grinding disc 11 and reducing the difficulty for the staff to clean the lower grinding disc 11.

[0035] A limiting groove 55 is formed on the upper surface of the second support rod 31. A limiting device 6 is set on the second support rod 31 to limit the connecting rod 42. The limiting device 6 includes a limiting rod 61 and a compression spring 62. The limiting rod 61 has a round rod structure and is slidably disposed in the limiting groove 55. An inclined surface is formed on the edge where the upper surface of the limiting rod 61 intersects with its side wall. One end of the compression spring 62 is fixed to the bottom surface of the limiting rod 61, and the other end of the compression spring 62 is fixed to the inner bottom wall of the limiting groove 55. A limiting hole 63 matching the limiting rod 61 is formed on the bottom surface of the connecting rod 42.

[0036] When the worker needs to clean the lower grinding disc 11, they need to rotate the rotating plate 41 towards the second support rod 31, which will cause the connecting rod 42 to press against the inclined surface, thereby allowing the limiting rod 61 to move completely into the limiting groove 55. Subsequently, when the connecting rod 42 is aligned with the second support rod 31, the limiting groove 55 is aligned with the limiting hole 63, so that the limiting rod 61 is connected to the limiting hole 63 under the action of the compression spring 62, thereby blocking the connecting rod 42. Furthermore, the worker only needs to slide the rotating plate 41 downwards to adjust the height of the nozzle 54, thereby improving the cleaning effect of the nozzle 54.

[0037] A drive groove 7 is formed through the inner wall of the limiting groove 55. The drive rod 71 is a rectangular rod structure that is slidably disposed within the drive groove 7 and is fixed to the limiting rod 61. After cleaning, to reduce interference from the rotating plate 41 on the grinding work, the worker needs to slide the drive rod 71 downwards, which will cause the limiting rod 61 to move downwards along with the drive rod 71, thereby separating the limiting rod 61 from the limiting hole 63. At this time, the worker only needs to rotate the rotating plate 41 in the opposite direction to reset the rotating plate 41.

[0038] The baffle 8 is a sheet-like structure, fixed to the side wall of the second support rod 31, and used to block the connecting rod 42. The stop block 81 is a block-like structure, fixed to the inner wall of the baffle 8. The side wall of the connecting rod 42 is provided with a fixing hole 82 that matches the stop block 81, and the bottom surface of the rotating plate 41 is provided with a through groove 9 for the baffle 8 to pass through.

[0039] When the operator rotates the rotating plate 41 towards the second support rod 31, the baffle 8 blocks the connecting rod 42, reducing the difficulty for the operator to align the connecting rod 42 with the second support rod 31. When the connecting rod 42 is aligned with the second support rod 31, the stop block 81 connects with the fixing hole 82, thereby limiting the connecting rod 42 in the vertical direction. This reduces the probability of the connecting rod 42 separating from the second support rod 31 when the operator moves the rotating plate 41 upwards, thus improving the operator's user experience.

[0040] The operating principle of the double-sided grinding device for high-precision optical element processing in this embodiment is as follows: When the operator needs to grind the optical element, the operator places the optical element on the lower grinding disc 11 and activates the transmission device 21. This causes the upper grinding disc on the transmission device 21 to move downward and press against the optical element, thereby allowing the upper and lower grinding discs 11 to cooperate and grind the optical element. Subsequently, after the optical element is ground, the operator needs to reset the transmission device 21. A large amount of impurities may remain on the lower grinding disc 11. At this time, the operator connects the connecting rod 42 to the second support rod 31 and activates the cleaning device 5. This allows the cleaning device 5 to continuously clean the lower grinding disc 11, thereby reducing the difficulty for the operator in cleaning the lower grinding disc 11.

[0041] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
