Description

Technical Field

[0001] This utility model relates to the field of precision vibration reduction technology, specifically to a vibration reduction platform. Background Technology

[0002] With the continuous improvement of the accuracy of ultra-precision machining equipment and measuring instruments, the vibration of their working environment is becoming more demanding in terms of micro-amplitude and wider frequency bandwidth, which in turn puts forward more stringent requirements on the vibration reduction performance of vibration damping tables.

[0003] In existing technologies, vibration damping platforms often use passive damping elements (e.g., gas springs) or a single active damping element. Passive damping elements are difficult to handle low-frequency and variable load conditions during vibration damping. The load-bearing capacity and control freedom of a single active damping element are limited. Furthermore, simply stacking multiple passive damping elements or multiple active damping elements often results in poor coordination, uneven system stiffness, and large space occupation, making it difficult to achieve high-performance vibration suppression in a limited space. Utility Model Content

[0004] Based on the above description, this utility model provides a vibration reduction platform, which aims to solve the problems of existing magnetic levitation vibration dampers where the magnetic levitation structure requires repeated disassembly and assembly of locking parts when adjusting the distance between the two inner magnetic rings, resulting in a cumbersome adjustment process and low positioning accuracy of the inner magnetic rings.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A vibration damping platform includes a magnetic levitation vibration damper, a first connecting plate, and a second connecting plate; multiple magnetic levitation vibration dampers are configured, the second connecting plate is arranged parallel to the first connecting plate, and a receiving space is formed between the second connecting plate and the first connecting plate, and all the magnetic levitation vibration dampers are arranged in an array within the receiving space.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the magnetic levitation damper includes a housing and a damping assembly. The housing has a receiving cavity, and the damping assembly includes a central shaft, a rotating sleeve, a first annular magnetic element, and a second annular magnetic element. The central shaft is movably disposed within the receiving cavity, and the rotating sleeve is screwed onto the central shaft. Two first annular magnetic elements are configured, and the two first annular magnetic elements are arranged sequentially along the axial direction of the central shaft. One first annular magnetic element is sleeved on the rotating sleeve, and the other first annular magnetic element is sleeved on the central shaft. The second annular magnetic element is disposed outside the two first annular magnetic elements.

[0009] Furthermore, the outer surface of the rotating sleeve is provided with a force-applying portion, which is constructed in a polygonal shape.

[0010] Furthermore, the vibration damping assembly includes a first locking member for restricting the axial movement of the rotating sleeve along the central axis.

[0011] Furthermore, it includes a connecting seat and a limiting seat, the connecting seat and the limiting seat being disposed at both ends of the housing in a corresponding manner, and the two ends of the central shaft being connected to the connecting seat and the limiting seat in a corresponding manner.

[0012] Furthermore, the vibration damping component includes at least two elastic elements, which are arranged sequentially along the axial direction of the central axis. The two elastic elements are correspondingly disposed at both ends of the two central axes. Both elastic elements are perpendicular to the central axis. The elastic element near the connecting seat is connected to the connecting seat and the end of the central axis near the connecting seat by a plurality of fasteners.

[0013] Furthermore, it includes at least one voice coil motor, which is disposed within the receiving space.

[0014] Furthermore, it includes multiple limiting components, with each limiting component having its two ends connected to the first connecting plate and the second connecting plate in a one-to-one correspondence.

[0015] Furthermore, the first connecting plate has stepped holes for each of the limiting components. The limiting component includes a limiting post, a sleeve, and a second locking member.

One end of the sleeve passes through the stepped hole and is inserted into the insertion hole. One end of the second locking member passes through the sleeve and is connected to the connecting hole.

[0016] Furthermore, it includes a displacement sensor, which is disposed within the accommodating space.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0018] (1) This utility model uses multiple magnetic levitation vibration dampers to support the precision equipment above, so that the load of the precision equipment can be evenly distributed on each magnetic levitation vibration damper, thereby improving the load-bearing capacity of the vibration damping platform. At the same time, multiple magnetic levitation vibration dampers can work together to counteract vibrations in different directions, thereby achieving efficient suppression of multi-degree-of-freedom vibrations.

[0019] (2) By using the threaded connection between the rotating sleeve and the central shaft, this utility model can improve the convenience of adjusting the distance between the two first annular magnetic components during the process of adjusting the distance, eliminating the need to repeatedly disassemble and reassemble the locking components; on the other hand, it ensures that the angle input of the rotating sleeve is accurate, thus guaranteeing the displacement accuracy of the first annular magnetic component.

This avoids tool slippage, ensures adjustment accuracy, and prevents thread damage.

[0021] (4) The present invention uses the first locking member to adjust the distance between the two first annular magnetic members and then moves the locking nut toward the rotating sleeve, so that the locking nut is close to the rotating sleeve and restricts the axial degree of freedom of the rotating sleeve, thereby preventing the rotating sleeve from loosening during vibration.

[0041] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

Therefore, the exemplary terms "below" and "below" can include both upper and lower orientations. Furthermore, the device may also include other orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptive terms used herein will be interpreted accordingly.

[0044] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0045] Reference Figures 1 to 2 As shown, this utility model provides a technical solution: a vibration reduction platform, including a magnetic levitation vibration damper 10, a first connecting plate 20 and a second connecting plate 30. Multiple magnetic levitation vibration dampers 10 are configured. The second connecting plate 30 is arranged parallel to the first connecting plate 20, and a receiving space is formed between the second connecting plate 30 and the first connecting plate 20. All magnetic levitation vibration dampers 10 are arranged in an array within the receiving space.

[0046] According to this embodiment, multiple magnetic levitation vibration dampers 10 can jointly support the precision equipment above, allowing the load of the precision equipment to be evenly distributed across each magnetic levitation vibration damper 10, thereby improving the load-bearing capacity of the vibration damping platform. Simultaneously, the multiple magnetic levitation vibration dampers 10 can work collaboratively to counteract vibrations in different directions, achieving efficient suppression of multi-degree-of-freedom vibrations. Furthermore, the array-style layout avoids local resonance, thereby enhancing the stability and vibration suppression effect of the vibration damping platform.

[0047] Reference Figures 3 to 5As shown, in some embodiments, the magnetic levitation damper 10 includes a housing 11 and a damping assembly 12. The housing 11 has a receiving cavity 111. The damping assembly 12 includes a central shaft 121, a rotating sleeve 122, a first annular magnetic element 123, and a second annular magnetic element 124. The central shaft 121 is movably disposed within the receiving cavity 111. The rotating sleeve 122 is screwed onto the central shaft 121. Two first annular magnetic elements 123 are configured, and the two first annular magnetic elements 123 are arranged sequentially along the axial direction of the central shaft 121. One first annular magnetic element 123 is sleeved on the rotating sleeve 122, and the other first annular magnetic element 123 is sleeved on the central shaft 121. The second annular magnetic element 124 is disposed outside the two first annular magnetic elements 123.

[0048] For example, both the first annular magnetic element 123 and the second annular magnetic element 124 can be annular permanent magnets, etc.

[0049] In this embodiment, the two first annular magnetic elements 123, with their same poles facing each other, generate an axial repulsive force, forming passive levitation. The second annular magnetic element 124, with its opposite poles facing the first annular magnetic element 123, forms a radial constraint magnetic field, suppressing lateral displacement. When the magnetic levitation damper 10 is subjected to vibration, the central shaft 121 moves along its own axial direction, driving the two first annular magnetic elements 123 to move. Due to the influence of the magnetic fields of the two first annular magnetic elements 123 and the second annular magnetic element 124, the two first annular magnetic elements 123 and the second annular magnetic element 124 generate an attractive force, driving the central shaft 121 to move, so that the two first annular magnetic elements 123 can be reset, achieving efficient vibration isolation and stable compensation for gravity.

[0050] When adjusting the distance between the two first annular magnetic components 123, the rotating sleeve 122 is rotated. The threaded engagement between the rotating sleeve 122 and the central shaft 121 converts the rotational motion into axial displacement. This adjusts the angle of the rotating sleeve 122, changing the distance between the two first annular magnetic components 123, thereby dynamically adjusting the magnitude of the repulsive force and achieving stepless adjustment of the damping stiffness. In this way, the threaded engagement between the rotating sleeve 122 and the central shaft 121 improves the convenience of adjusting the distance, eliminating the need for repeated disassembly and reassembly of the locking components. Furthermore, it ensures precise angle input of the rotating sleeve 122, guaranteeing the displacement accuracy of the first annular magnetic components 123.

[0051] Reference Figure 5 As shown, in some embodiments, the outer surface of the rotating sleeve 122 is provided with a force-applying portion 1221, which is constructed as a polygon.

[0052] For example, a polygon can be a triangular, quadrilateral, pentagonal, hexagonal, heptagonal, or octagonal shape, etc.

[0053] According to this embodiment, when adjusting the spacing between the two first annular magnetic elements 123, a tool engages with the polygonal surface to transmit torque to the rotating sleeve 122. This prevents tool slippage, ensures adjustment accuracy, and prevents thread damage.

[0054] Reference Figure 4 As shown, in some embodiments, the vibration damping assembly 12 includes a first locking member 125 for limiting the axial movement of the rotating sleeve 122 along the central axis 121.

[0055] For example, the first locking member 125 may be a locking nut or the like, which is screwed onto the rotating sleeve 122.

[0056] According to this embodiment, after adjusting the distance between the two first annular magnetic elements 123, the locking nut is moved toward the rotating sleeve 122 so that the locking nut is tightly attached to the rotating sleeve 122, restricting the axial degree of freedom of the rotating sleeve 122, thereby preventing the rotating sleeve 122 from loosening during vibration.

[0057] Reference Figure 4 As shown, in some embodiments, the magnetic levitation damper 10 includes a connecting seat 13 and a limiting seat 14, which are respectively disposed at both ends of the housing 11, and the two ends of the central shaft 121 are respectively connected to the connecting seat 13 and the limiting seat 14.

[0058] For example, the limiting seat 14 is fixed to the second connecting plate 30.

[0059] According to this embodiment, the connecting seat 13 and the limiting seat 14 provide axial support boundaries, so that the central shaft 121 retains only the axial vibration degree of freedom.

[0060] Reference Figure 4 As shown, in some embodiments, the vibration damping component 12 includes at least two elastic elements 126. The two elastic elements 126 are arranged sequentially along the axial direction of the central shaft 121. The two elastic elements 126 are correspondingly disposed at both ends of the two central shafts 121. Both elastic elements 126 are perpendicular to the central shaft 121. The elastic element 126 near the connecting seat 13 is connected to the connecting seat 13 and the end of the central shaft 121 near the connecting seat 13 by a plurality of fasteners.

[0061] For example, the elastic element 126 can be a leaf spring, etc. The stiffness of the leaf spring in its radial direction is much greater than its stiffness in its axial direction. The fastener can be a bolt or screw, etc.

[0062] According to this embodiment, when the central shaft 121 moves along its own axial direction, the elastic element 126 generates a restoring force after being compressed, which works in conjunction with the two first annular magnetic elements 123 and the second annular magnetic element 124 to achieve vibration reduction in the axial direction of the central shaft 121.

[0063] Reference Figure 4 As shown, in some embodiments, the vibration damping assembly 12 includes a vibration damping rod 127, one end of which is fixed to the first connecting plate 20, and the other end of which extends into the central shaft 121 and is suspended freely.

[0064] According to this embodiment, the damping rod 127 is directly connected to the first connecting plate 20, eliminating the need for connecting components for the damping rod 127. This reduces the distance between the first connecting plate 20 and the second connecting plate 30, thereby miniaturizing the vibration damping platform as much as possible. (Refer to...) Figure 2 As shown, in some embodiments, the vibration damping platform includes at least one voice coil motor 40, which is disposed within the receiving space.

[0065] For example, the voice coil motor 40 is fixed to the second connecting plate 30, and the output end of the voice coil motor 40 is fixed to the first connecting plate 20. The specific number of voice coil motors 40 depends on the actual situation and will not be described in detail here.

[0066] In this embodiment, the voice coil motor 40 outputs an active compensation force to counteract low-frequency, large-amplitude disturbances. This combined active and passive vibration reduction enhances the vibration damping capability.

[0067] The damping rod 127 is directly connected to the first connecting plate 20, which can reduce the number of parts of the magnetic levitation damper 10, making the magnetic levitation damper 10 miniaturized, thereby reducing the space occupied.

[0068] Reference Figures 1 to 2 As shown, in some embodiments, the vibration damping platform includes multiple limiting components 50, with each limiting component 50 having its two ends connected to the first connecting plate 20 and the second connecting plate 30 in a one-to-one correspondence.

[0069] According to this embodiment, the limiting component 50 can restrict the first connecting plate 20 from moving in the vertical direction, prevent the first connecting plate 20 from moving laterally, and prevent the platform from overturning.

[0070] Reference Figures 6 to 7 As shown, in some embodiments, the first connecting plate 20 has a stepped hole 21 for each limiting component 50. The limiting component 50 includes a limiting post 51, a sleeve 52, and a second locking member 53. One end of the limiting post 51 has an insertion hole and a connecting hole extending along its own axis. The other end of the limiting post 51 is connected to the second connecting plate 30. One end of the sleeve 52 passes through the stepped hole 21 and is inserted into the insertion hole. One end of the second locking member 53 passes through the sleeve 52 and is connected to the connecting hole.

[0071] For example, the second locking element 53 can be a limit bolt, etc.

[0072] According to this embodiment, when the first connecting plate 20 moves in the vertical direction, the sleeve 52 moves axially along the second locking member 53 through the threaded engagement of the second locking member 53 with the limiting post 51, so as to realize the floating of the first connecting plate 20.

[0073] For ease of assembly of limit component 50, refer to Figures 6 to 7 As shown, the first connecting plate 20 has a movable groove 22 corresponding to each stepped hole 21. One end of the movable groove 22 communicates with the stepped hole 21, and the other end communicates with the outside of the first connecting plate 20. The limiting component 50 includes a centering bushing 54, one end of which passes through the movable groove 22 and contacts the sleeve 52. During the assembly of the second locking member 53, the centering bushing 54 limits the sleeve 52 to facilitate the assembly of the second locking member 53. After the second locking member 53 is assembled, the centering bushing 54 can be removed.

[0074] For example, the centering bushing 54 can be Y-shaped, etc.

[0075] Reference Figure 2 As shown, in some embodiments, the vibration damping platform includes a displacement sensor 60, which is disposed within the accommodating space.

[0076] For example, the displacement sensor 60 is fixed to the second connecting plate 30, and the measuring end of the displacement sensor 60 is fixed to the first connecting plate 20.

[0077] According to this embodiment, the displacement sensor 60 measures the displacement of the first connecting plate 20 in real time to reflect the intensity of external vibration and impact.

[0078] Reference Figure 2 As shown, in some embodiments, the vibration damping platform includes at least two velocity sensors 70, all of which are located within the accommodating space.

[0079] For example, the speed sensor 70 is fixed to the second connecting plate 30, and the measuring end of the speed sensor 70 is fixed to the first connecting plate 20. Of the two speed sensors 70, one speed sensor 70 serves as a feedforward speed sensor 70, and the other speed sensor 70 serves as a feedback speed sensor 70.

[0080] According to this embodiment, the feedforward velocity sensor 70 is used to pre-detect the external vibration velocity. Before the vibration is transmitted to the vibration damping platform, the voice coil motor 40 is activated for compensation, thereby improving the suppression efficiency of sudden impacts. The feedback velocity sensor 70 is used to measure the vibration velocity of the vibration damping platform itself. After the vibration is transmitted to the vibration damping platform, the magnetic levitation vibration damper 10 is activated to suppress the platform's own resonance.

[0081] Reference Figure 2 and Figure 9As shown, in some embodiments, the vibration damping platform includes a main control component 80, which is disposed within the accommodating space. The main control component 80 includes a control board 81. The controlled end of each magnetic levitation vibration damper 10 and the controlled end of each voice coil motor 40 are electrically connected to the control end of the control board 81. The output end of the displacement sensor 60 and the output end of each speed sensor 70 are electrically connected to the input end of the control board 81.

[0082] According to this embodiment, the control board 81 receives signals from each sensor to control the activation of each magnetic levitation damper 10 and each voice coil motor 40 to achieve vibration isolation and damping.

[0083] Reference Figure 2 and Figure 9 As shown, in some embodiments, the main control component 80 includes a conditioning board 82 connected to the control board 81. The output terminals of the displacement sensor 60 and each speed sensor 70 are electrically connected to the input terminals of the conditioning board 82, and the output terminals of the conditioning board 82 are electrically connected to the input terminals of the control board 81.

[0084] For example, the conditioning plate 82 is detachably connected to the control plate 81.

[0085] According to this embodiment, before each sensor feeds back a signal to the control board 81, the signal is first filtered and amplified by the conditioning board 82 before being transmitted to the control board 81, thereby suppressing noise and improving the signal-to-noise ratio.

[0086] Reference Figure 2 and Figure 9 As shown, in some embodiments, the main control component 80 includes a motor board 83, the controlled end of the motor board 83 is electrically connected to the control end of the control board 81, and the controlled end of each voice coil motor 40 is electrically connected to the control end of the motor board 83.

[0087] According to this embodiment, the motor board 83 converts the control command into the drive current of the voice coil motor 40 to achieve control of the voice coil motor 40.

[0088] Reference Figure 2 and Figure 9 As shown, in some embodiments, the main control component 80 includes a heat sink 84, which is disposed on the control board 81.

[0089] For example, the heat sink 84 can be a heat sink or a cooling fan, etc.

[0090] According to this embodiment, the heat dissipation component 84 improves the heat conduction efficiency, reduces the temperature rise of the control board 81, and ensures real-time control by the control board 81.

[0091] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
