DETAILED DESCRIPTION
[0031] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.
[0032] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0033] Embodiment 1, as Figure 1-Figure 10 As shown, a platform device for producing optical components according to an embodiment of the present application includes a base 1, a rotating platform 2 and a compensation mechanism 3.
[0034] In a specific embodiment of the present application, the base 1 is composed of a fixed part and a rotating part coaxially arranged, wherein the rotating part and the fixed part are rotatably connected.
[0035] Specific as Figure 1 and Figure 2As shown, the fixed part of the base 1 includes: a support 11, a fixing ring 12, an axial positioning ring 13 and a rotating support ring 14. The support 11 is hollow at the axis center, and the fixing ring 12 is coaxially fixed in the support 11; the axial positioning ring 13 is coaxially fixed to the fixing ring 12, and its inner diameter is larger than the outer diameter of the fixing ring 12; the rotating support ring 14 is coaxially fixed to the upper end surface of the support 11, as shown in FIG. Figure 2 As shown, the fixing ring 12, the axial positioning ring 13 and the rotating support ring 14 are sequentially distributed from inside to outside in the radial direction, and sequentially distributed from bottom to top in the axial direction.
[0036] Furthermore, the rotating part of the base 1 includes: a rotating positioning ring 15 and a rotating expansion platform 16 . The rotating positioning ring 15 is rotatably inserted into the axial positioning ring 13 ; the rotating expansion platform 16 is coaxially fixed to the rotating positioning ring 15 and is rotatably connected to the rotating support ring 14 .
[0037] It should be noted that, in the specific embodiment of the present application, the rotational plug-in relationship between the rotating positioning ring 15 and the axial positioning ring 13, combined with the rotational connection relationship between the rotating expansion table 16 and the rotating support ring 14, enables the axial deflection angle of the rotating expansion table 16 to be reduced as much as possible during the rotation process, and adopts double-layer axial positioning to ensure the axial accuracy of the rotating expansion table 16 to a certain extent.
[0038] In a specific embodiment of the present application, the rotating platform 2 is composed of a shell and a driving part coaxially arranged, wherein the driving part is arranged in the shell, the shell and the fixed part of the base 1 are coaxially fixed, and the rotating end of the driving part rotates and extends out of the shell and is coaxially fixed with the rotating part of the base 1.
[0039] Specific as Figure 2 and Figure 3 As shown, the housing of the rotating platform 2 includes: a motor housing 21 and a protective shell 23 which are coaxially fixed. The motor housing 21 is fixedly inserted into the fixing ring 12 , and the protective shell 23 and the motor housing 21 are coaxially fixed.
[0040] Furthermore, the driving part of the rotating platform 2 includes: a rotating motor 22, which is fixedly arranged in the motor housing 21, and its rotating end includes a rotating shaft 24 keyed to the rotating motor 22, the rotating shaft 24 rotates through the protective shell 23 and is sleeved with a thrust bearing 25, the thrust bearing 25 is fixedly connected to the upper end surface of the protective shell 23, and one end of the rotating shaft 24 extending from the thrust bearing 25 is fixedly connected to a transition flange 26.
[0041] It can be understood that in the specific embodiment of the present application, the output shaft of the rotating motor 22 will drive the rotating shaft 24 and the transition flange 26 to rotate synchronously in the same direction, and the support leg bearing 25 will limit the axial movement of the rotating shaft 24. Specifically, the rotating platform 2 can be an air-floating spindle in the prior art, and its specific working principle is already very mature in the prior art and will not be elaborated here.
[0042] In the specific embodiments of the present application, Figure 2-Figure 6 As shown, the compensation mechanism 3 includes a boss 31, a crimping block 32 and a plurality of centrifugal components 33, the boss 31 is coaxially fixed to the rotating end of the rotating platform 2, the crimping block 32 is sealingly sleeved on the boss 31 and fixed to the rotating part of the base 1, and a plurality of centrifugal components 33 are evenly fixed to the boss 31 in the circumferential direction and sealedly inserted in the crimping block 32; a through channel is radially arranged inside the centrifugal component 33, and the channel in the centrifugal component 33 is communicated with the annular channel in the crimping block 32; a centrifugal piston block 4 is sealingly and slidably arranged in the channel in the centrifugal component 33, and the side of the centrifugal piston block 4 facing the side wall of the boss 31 is filled with compressible gas, and the side of the centrifugal piston block 4 facing the annular channel in the crimping block 32 is filled with hydraulic oil.
[0043] Among them, the transition flange 26 and the boss 31 are coaxially fixed, and the end of the crimping block 32 away from the boss 31 is fixed with the end platform 27. It should be noted that the end platform 27 can be adaptively replaced according to actual use to meet various usage scenarios.
[0044] Furthermore, a connecting flange 17 is coaxially fixed to the bottom end of the crimping block 32, and the connecting flange 17 and the rotating extension table 16 are coaxially fixed. In this way, the rotating extension table 16 realizes axial positioning of the compensation mechanism 3 from the crimping block 32, and the rotating extension table 16 realizes axial positioning from the motor housing 21 through the rotating positioning ring 15, the axial positioning ring 13 and the fixing ring 12, and the rotating extension table 16 is also positioned on the support 11 through the rotating support ring 14. Therefore, the base 1 is used to realize three-point positioning of the rotating platform 2 and the compensation mechanism 3, thereby further ensuring the axial stability of a platform device for producing optical components of the present application.
[0045] Further, such as Figure 5 , Figure 6 and Fig.10 As shown, a recessed portion 321 is coaxially arranged at the bottom end of the crimping block 32, and a plurality of mounting grooves 322 are evenly arranged on the circumferential side of the recessed portion 321. The plurality of mounting grooves 322 are interconnected through an annular channel arranged in the crimping block 32, and the annular channel is an annular through groove 323, which is located on the outer side of the plurality of mounting grooves 322.
[0046] Furthermore, the boss 31 is sealably inserted into the recessed portion 321, and the centrifugal component 33 is sealably embedded in the mounting groove 322. It should be noted that in the specific embodiment of the present application, the centrifugal component 33 blocks the mounting groove 322 in the radial direction, and the fixed connection between the centrifugal component 33 and the side wall of the raised end of the boss 31 is a detachable fixed connection to facilitate installation, disassembly and maintenance.
[0047] Furthermore, the radially penetrating channel in the centrifugal assembly 33 is a radial channel 331 .
[0048] It can be seen that the radial channel 331 and the mounting groove 322 are communicated.
[0049] Furthermore, the centrifugal piston block 4 seals and slides in the radial channel 331, and the initial pressure value of the compressible gas filled by the multiple centrifugal piston blocks 4 toward the side wall of the boss 31 is the same, so that the distance between the multiple centrifugal piston blocks 4 and the axis center in the crimping block 32 is the same, and the multiple centrifugal piston blocks 4 all have the ability to reset.
[0050] The following describes the use process of a platform device for producing optical components according to an embodiment of the present application with reference to the accompanying drawings:
[0051] During specific use, the optical components in the processing process are placed on the end platform 27, and the rotating motor 22 drives the rotating shaft 24 to rotate, and then the boss 31, the crimping block 32, the rotating expansion platform 16, and the end platform 27 are driven to rotate synchronously in the same direction through the transition flange 26. The rotating expansion platform 16 cooperates with the base 1 to realize three-point axial positioning of the rotating platform 2 and the compensation mechanism 3, which reduces the axial deflection of the end platform 27 caused by external forces during the rotation process to a certain extent. At the same time, the rotating expansion platform 16 plays a further protective role on the electrode shell 21 and the protective shell 23 to prevent the dirt generated during the working process from polluting and interfering with the components below;In the initial state, since the centrifugal components 33 on the boss 31 are evenly distributed in the mounting groove 322 in the circumferential direction, and the centrifugal piston block 4 is radially sealed and slidably connected in the centrifugal component 33, and the inner side of the centrifugal piston block 4 is a compressible gas of a certain pressure, and the outer side is a hydraulic oil of the same pressure, it can be understood that when the end platform 27 carries the optical components, the end platform 27 is subjected to external force, and once the axial deviation occurs, the axial deviation will be directly brought between the crimping block 32 and the boss 31. It can be understood that when the crimping block 32 has an axial deviation on the boss 31 (the present application will enlarge the deflection angle for description), , for ease of understanding, the actual working process will not produce the deflection angle described below), which will cause the crimping block 32 and the boss 31 to tend to approach each other on one side and tend to move away from each other on the other side in the radial direction. At this time, the hydraulic oil originally evenly distributed in the multiple mounting grooves 322, radial channels 331 and annular through grooves 323 on the outside of the centrifugal piston block 4 will become unbalanced, that is, the hydraulic oil will flow to the side away from each other, while the hydraulic oil stock on the side close to each other will decrease. At the same time, the centrifugal piston block 4 at the corresponding position will also have a corresponding radial displacement under the action of pressure conservation on both sides. At this time, the crimping block 32 and the boss 31 will tend to move closer to each other on one side and away from each other on the other side. The platform 31 will be subjected to the external force and there will be a certain axial deflection. However, during the rotation process, especially when rotating at a high speed, the centrifugal piston block 4 will have a tendency of radial displacement to the outside under the action of the centrifugal force. Therefore, it can be understood that the original axial deflection caused the multiple centrifugal piston blocks 4 to have uneven radial displacement in the circumferential direction, resulting in uneven distribution of hydraulic oil out of the multiple centrifugal piston blocks 4. Now, due to the action of the centrifugal force, the multiple centrifugal piston blocks 4 will all have an outward radial force, and because there is compressible gas of equal pressure inside, the multiple centrifugal piston blocks 4 will gradually form a dynamic Dynamic balancing is performed to make the hydraulic oil evenly distributed on the outside of the centrifugal piston block 4. In this way, the axial deflection originally caused by external force is alleviated, improved and corrected. The radial force generated during the dynamic balancing process is used to offset the axial deflection force applied to the crimping block 32 by the external force, thereby ensuring the stability of the crimping block 32 during rotation. The dynamic balancing ability between the crimping block 32 and the boss 31 is used to avoid the external force being directly transmitted to the rotating shaft 24 and causing damage to the rotating shaft 24. This design improves the service life and rotation accuracy of the entire platform device for optical component production and ensures the processing accuracy of optical components. ;
[0052] Embodiment 2: In the related art, the platform device for producing optical components adopts a compensation mechanism 3 to utilize dynamic balance to alleviate, reduce, and correct the axial deflection generated at the end platform 27. Therefore, the centrifugal piston block 4 therein will produce radial displacement in the corresponding radial channel 331 to ensure the uniform distribution of the hydraulic oil on the outside of the centrifugal piston block 4. The radial displacement of the centrifugal piston block 4 will cause wear between the centrifugal piston block 4 and the inner wall of the radial channel 331. Once the sealing performance between the centrifugal piston block 4 and the radial channel 331 is reduced due to wear, it will affect the ability of the entire platform device for producing optical components to correct the axial deflection, and have an adverse effect on the production and processing of optical components.
[0053] According to some embodiments of the present application, Figure 6-Figure 9 As shown, the structures and sizes of the multiple centrifugal piston blocks 4 are exactly the same, and they all include: a piston shell 41, at least two rubber rings 42, two floating sheets 43 and a movable component 44. The piston shell 41 is sealingly slidable in the radial channel 331; the two rubber rings 42 are symmetrically embedded in the outer wall of the piston shell 41; the two floating sheets 43 are symmetrically arranged in the piston shell 41, and are sealingly slidably connected to the inner wall of the piston shell 41; and the movable component 44 is sealingly slidably plugged into the piston shell 41.
[0054] Among them, Fig. 9 As shown, two sealing grooves 411 are symmetrically arranged on the side wall of the piston housing 41, and the two sealing grooves 411 correspond to two rubber rings 42 respectively, so that the rubber rings 42 can be sealed and embedded on the outer wall of the piston housing 41. A plurality of radial through holes 412 are evenly arranged circumferentially on the sealing groove 411. The piston housing 41 is divided into three chambers. The two chambers at the two ends are symmetrically arranged and connected with the corresponding sealing grooves 411 through the radial through holes 412. Two limit rings 413 are symmetrically arranged on the inner wall of the middle chamber for limiting the axial displacement of the two floating plates 43. A plurality of axial through holes 414 are symmetrically arranged at both ends of the middle chamber.
[0055] It should be noted that the space between the two floating plates 43 is filled with compressible gas, and the two sides of the two floating plates 43 are filled with hydraulic oil. Specifically, the space between the two chambers at both ends of the piston housing 41 and the corresponding floating plates 43 is filled with hydraulic oil.
[0056] It is further necessary to explain that if Figure 7 As shown, the two floating sheets 43 are respectively located on the outsides of the two limiting rings 413 .
[0057] like Figure 8As shown, the movable component 44 includes: a shaft rod 441, two end plates 442 and a damping plate 443. The shaft rod 441 is sealed and slidably inserted into the piston housing 41; the two end plates 442 are symmetrically fixed to the two ends of the shaft rod 441; the damping plate 443 is fixed to the shaft rod 441 and is located between the two floating plates 43.
[0058] It should be noted that, in the initial state, the two floating sheets 43 are not in contact with the corresponding limiting rings 413. Figure 7 As shown, the two end plates 442 are symmetrically located on both sides of the piston housing 41.
[0059] Therefore, in specific use, when the boss 31 and the crimping block 32 rotate, the centrifugal piston block 4 is radially displaced in the corresponding radial channel 331 (for ease of understanding, as Figure 7 As shown, the centrifugal piston block 4 is displaced to the left or right for description), when the centrifugal piston block 4 is displaced to the left (as shown in FIG. Figure 7 41, the radial through hole 412 on the right side of the cylinder 440 is used to press the piston ring 42 against the piston ring 42, and the radial through hole 413 on the right side of the cylinder 440 is used to press the piston ring 42 against the piston ring 42, so that the pressure inside the cylinder 440 is reduced. When the block 4 is displaced to the right, the two end plates 442 drive the shaft 441 to move to the left relative to the piston shell 41, so that the damping plate 443 will compress the compressible gas on its left side, forcing the floating plate 43 on the left side to squeeze the hydraulic oil on the left side of the floating plate 43, forcing the hydraulic oil on this side to generate an outward radial force on the rubber ring 42 on this side, forcing the sealing performance between the rubber ring 42 on this side and the inner wall of the radial channel 331 to be enhanced. In this way, no matter how the centrifugal piston block 4 is radially displaced in the radial channel 331, there will always be a rubber ring 42 and the radial channel 331 with good sealing performance, which ensures the sealing strength between the centrifugal piston block 4 and the radial channel 331, enhances the service life of the centrifugal piston block 4 in the crimping block 32, and similarly enhances the dynamic balancing ability of the centrifugal piston block 4.
[0060] Embodiment 3: In the related art, in the platform device for producing optical components, during the processing of the optical components, once the external pressure is too large, the dynamic balance generated by the centrifugal piston block 4 will be broken, and then a certain axial deflection will be generated at the end platform 27, making it impossible to perform normal processing operations on the optical components.
[0061] According to some embodiments of the present application, Figure 4-Figure 6 and Fig.10 As shown, the bottom end of the crimping block 32 is sealed and slidably plugged with an auxiliary mechanism 5, which includes: an abutment seat 51 and a plurality of connecting channels 52, the abutment seat 51 is arranged in a ring shape, and an annular protrusion is fixedly connected to the upper part of the ring, and the annular protrusion is sealed and slidably plugged into the crimping block 32; the plurality of connecting channels 52 are evenly arranged circumferentially in the crimping block 32.
[0062] It should be noted that the lower portion of the abutting seat 51 abuts against the upper end surface of the boss 31 .
[0063] The bottom end of the crimping block 32 is coaxially provided with an axial slide groove 324 , one end of the connecting channel 52 is connected to the annular through groove 323 , and the other end of the connecting channel 52 is connected to the axial slide groove 324 .
[0064] Furthermore, sealing rings 511 are provided on the inner and outer side sealing sleeves of the abutment seat 51, and the sealing rings 511 are embedded in the axial groove 324. It should be noted that the inner wall of the sealing ring 511 and the outer wall of the annular protrusion on the abutment seat 51 are sealed and slidably matched. Of course, in another embodiment of the present application, the sealing ring 511 can also be sealed and fixed to the abutment seat 51, and the outer wall of the sealing ring 511 and the inner wall of the axial groove 324 are sealed and slidably connected. The sealing ring 511 only plays a sealing role to prevent leakage of hydraulic oil.
[0065] It should be noted that the annular protrusion of the abutting seat 51 and the axial sliding groove 324 are coupled.
[0066] It should be further explained that an axial limit is provided between the abutment seat 51 and the axial groove 324 to prevent the abutment seat 51 from falling directly out of the axial groove 324. At the same time, in the initial rotation state (when no external force is applied), the axial groove 324 and the connecting channel 52 are filled with hydraulic oil.
[0067] Therefore, during specific use, when the end platform 27 is subjected to external force, due to the incompressible nature of the hydraulic oil, part of the external force will be transmitted to the upper end surface of the abutment seat 51 through the connecting channel 52 through the hydraulic oil, and a downward pressure will be applied to the upper end surface of the abutment seat 51, and the abutment seat 51 will transmit the force to the boss 31 abutting thereunder. In this way, the axial force will be borne by the boss 31, and the external force borne by the end platform 27 will be shared, thereby reducing the radial force borne by the annular groove 323, the radial channel 331 and the centrifugal piston block 4. By differentiating the force, the stability of the dynamic balance formed at the centrifugal piston block 4 is ensured. At the same time, the coupling cooperation between the abutment seat 51 and the axial groove 324 further limits the axial deflection of the crimping block 32 on the boss 31 from the outside. This design greatly suppresses the axial deflection of the end platform 27 and improves the machining accuracy of optical components.
[0068] It should be noted that the specific models and specifications of the connecting flange 17, the rotating motor 22, the thrust bearing 25, the transition flange 26, the rubber ring 42 and the sealing ring 511 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.
[0069] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
