Description

Technical Field

[0001] This application relates to the field of adjustable base technology, and in particular to a multi-dimensional adjustable support base and oscillator. Background Technology

[0002] In large scientific facilities such as free-electron laser accelerators, undulators are core components that generate high-intensity, highly collimated radiation beams. Because undulators significantly influence the stability of particle beam trajectories, their installation position accuracy is typically required to be within ±0.1 mm. However, undulators themselves are enormous, typically weighing around 12 tons, with individual support points requiring a load of ≥3 tons. Furthermore, to compensate for minute displacements caused by ground settlement and environmental thermal deformation, they must be mounted on support bases with high load-bearing capacity and precise positioning adjustment capabilities. In addition, due to the extremely compact space within the accelerator tunnel, the space allocated to the bottom of the support base for installation is usually very limited.

[0003] In existing technologies, combined adjustment mechanisms are typically used to support and adjust heavy-duty equipment such as oscillators. Specifically, existing technologies employ a superimposed scheme of worm gear and worm wheel combined with a two-dimensional translation module. The worm gear mechanism is arranged below the base, using the worm to drive the worm wheel to rotate and convert it into the vertical lifting motion of the lead screw, thereby achieving height adjustment in the Z-axis direction. Simultaneously, a cross-shaped translation stage consisting of linear guide rails, sliders, and drive lead screws is installed on the lifting platform to achieve horizontal displacement adjustment in the X and Y axes. Ultimately, this superimposed combination method achieves three-dimensional spatial adjustment functionality.

[0004] However, the adjustable support base of the prior art has the following shortcomings, specifically: Existing technology superimposes a translation mechanism on top of a lifting mechanism, resulting in an inability to compress the overall vertical dimensions of the device. Furthermore, to support a single-point load exceeding 3 tons and achieve self-locking, the worm gear mechanism must employ large-module gears, requiring space within the base to accommodate them. This leads to a bulky base that is difficult to fit into the confined installation space at the bottom of the undulator, impacting the compact layout of the accelerator beamline. Additionally, the worm gear mechanism is essentially a sliding friction transmission; under heavy loads of several tons, the contact stress between the gear teeth is high, easily causing tooth wear. This results in the support mechanism losing its original self-locking precision, causing the undulator to drift during long-term operation and failing to meet the stringent stability requirement of ±0.1mm.

[0005] Therefore, this application aims to solve the problems of existing adjustment bases using worm gear transmission, which result in bulky size and inability to meet the requirements of compact installation, and the fact that the worm gear transmission causes accelerated wear of transmission components due to high contact stress under heavy load conditions, thus failing to meet the adjustment accuracy requirements. Summary of the Invention

[0006] The main objective of this application is to provide a multi-dimensional adjustable support base and a oscillator, which aims to solve the problems of the large size of the adjustable base due to the use of worm gear transmission, which cannot meet the requirements of compact installation, and the accelerated wear of the worm gear transmission components due to high contact stress.

[0007] To achieve the above objectives, this application proposes a multi-dimensional adjustable support base, comprising: Fixed base; A translation module, which is connected to the fixed base, is used for rolling translation in a first direction and a second direction; The second and third inclined blocks are both connected to the side of the translation module away from the fixed base, and are closer to or further away from each other in the first or second direction; A first inclined block is slidably connected to the translation module along a third direction, and the inclined surface of the first inclined block is adapted to the inclined surface of the second inclined block and the inclined surface of the third inclined block. Wherein, the first direction and the second direction are perpendicular to each other on the same horizontal plane, and the third direction is perpendicular to the first direction and the second direction.

[0008] This application changes the traditional worm gear lifting structure, replacing it with a lifting mechanism using the inclined surfaces of the first, second, and third inclined blocks. Simultaneously, the friction of the inclined surfaces replaces the self-locking function of the worm gear, enabling precise translational compensation adjustment in any direction within three-dimensional space. This results in a more compact, smaller, novel, and reliable overall design. It not only solves the problem of large size in traditional adjustment devices but also possesses high load-bearing capacity, adjustment accuracy, and stability. It is suitable for precision installation in large scientific facilities where the mounting space for the undulator's feet is limited. The adjustment operation is simple, achieving a undulator position accuracy of ≤±0.1mm, greatly facilitating its assembly and use within the confined space of the undulator.

[0009] Furthermore, the inclined surface of the first inclined block facing the inclined surface of the second inclined block and the third inclined block is V-shaped, and the inclined surface of the first inclined block abuts against the inclined surface of the second inclined block and the inclined surface of the third inclined block, respectively.

[0010] Furthermore, a centering screw is connected to the side of the translation module facing the first inclined block; The centering screw is parallel to the third direction, passes through the first inclined block, and is slidably connected to the first inclined block.

[0011] Furthermore, a spherical washer is provided at the end of the first inclined block away from the second and third inclined blocks. The spherical washer is sleeved on the end of the centering screw and is used to support the foot.

[0012] Furthermore, a positioning screw is connected to the end of the centering screw that is away from the translation module; A round washer is connected to the end of the positioning screw away from the centering screw; The circular pad and the spherical pad are used to lock the foot onto the first inclined block.

[0013] Furthermore, the translation module is also equipped with a moving adjustment block, a guide tube, and a first adjusting screw; The movable adjustment block is slidably connected to the translation module and is located on the side of the second inclined block away from the third inclined block; One end of the guide tube is connected to the movable adjusting block, and the other end of the guide tube is connected to the second inclined block; The first adjusting screw is rotatably mounted on the translation module. The middle and end of the first adjusting screw are respectively provided with opposite threads, which respectively drive the moving adjusting block and the second inclined block to move closer or further apart.

[0014] Furthermore, the translation module includes a sandwich panel and a movable base plate; The sandwich panel is disposed between the fixed base and the movable base plate, a first roller group is disposed between the sandwich panel and the fixed base plate, and / or a second roller group is disposed between the sandwich panel and the movable base plate; The second and third inclined blocks are slidably connected to the movable base plate in the first or second direction.

[0015] Furthermore, the first roller group is composed of a plurality of first cylindrical rollers, and the axes of the plurality of first cylindrical rollers are parallel to the second direction; The second roller group consists of a plurality of second cylindrical rollers, the axes of which are parallel to the first direction.

[0016] Furthermore, a plurality of the first cylindrical rollers are disposed on the fixed base; Several second cylindrical rollers are disposed on the sandwich panel; The movable base plate has flanges extending to both ends of the sandwich panel in the first direction.

[0017] This application discloses an oscillator having multiple feet, each foot being placed on the first inclined block of the aforementioned multidimensional adjustable support base.

[0018] The above technical solution has the following advantages: The adjustable support base of this application presses the first inclined block by the second and third inclined blocks, so that the first inclined block can rise and fall stably. At the same time, it can achieve self-locking by relying on the friction between the first and second inclined blocks and between the first and third inclined blocks, without the need for an additional self-locking mechanism. It also avoids stress contact wear between the worm gear and the worm, which greatly improves the service life. In addition, while ensuring the compact structure of the adjustable support base, it can also support the feet of heavy oscillators.

[0019] The second inclined block can sink into the groove opened in the movable base plate, thereby further reducing the height of the adjustable base in the third direction. In addition, the weight of the foot can be supported on the centering screw, and can also be distributed to the second and third inclined blocks through the first inclined block, thereby achieving three parallel support points in the third direction, which greatly improves the stability and reliability of the support. Self-locking can be achieved by relying solely on the surface friction between the first and second inclined blocks and between the first and third inclined blocks, without the need to add an additional self-locking mechanism, thus maintaining a more compact overall structure.

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the following specific embodiments are merely illustrative of this application and do not constitute a limitation thereof.

[0023] As a key component of the free-electron laser large-scale scientific device, the accuracy of the undulator's installation position is crucial to the stability of the ion beam trajectory. It is necessary to ensure that its positional accuracy is less than ±0.1mm, while also compensating for installation position errors caused by ground settlement and structural deformation. Therefore, it is necessary to place a corresponding adjustable support base for each foot of the undulator.

[0024] Existing adjustable support bases mainly utilize worm gears to achieve lifting and adjustment. Because worm gears have a self-locking function, the worm drives the worm wheel to rotate and converts it into the vertical lifting and lowering motion of the lead screw to achieve height adjustment in the Z-axis direction. At the same time, a cross-shaped translation stage consisting of linear guides, sliders, and drive lead screws is installed on the lifting platform to achieve horizontal displacement adjustment in the X and Y axes. Finally, the adjustment function in three-dimensional space is achieved through this superimposed combination.

[0025] However, when the adjustable support base of the existing technology is driven by a worm gear, the undulator itself is heavy, weighing approximately 12 tons. If the undulator requires four feet, the load-bearing capacity of each adjustable support base must be greater than 3 tons. When the worm gear drive method needs to bear a weight of more than 3 tons, a large module gear must be selected to match the required load-bearing capacity. However, the large module gear will occupy the internal space of the adjustable support base, resulting in a large adjustable support base in the final product, which cannot be used in the narrow installation space at the bottom of the undulator, making it impossible to achieve a compact design for the entire device. In addition, when the contact stress of the worm gear is extremely high, the load-bearing capacity mainly relies on the tooth surface of the worm gear, which can easily lead to excessive stress and accelerated wear of the tooth surface. This causes the worm gear to fail to maintain the required self-locking accuracy for a long time, easily resulting in position drift and making it difficult to meet the requirement of a position accuracy of less than ±0.1 mm.

[0026] Therefore, the existing worm gear supports a large weight, which increases the overall height and size of the adjustable support base. At the same time, the wear of the worm gear will exacerbate the overall accuracy requirements. This application proposes an alternative support method to overcome the above technical problems.

[0027] like Figures 1 to 6As shown, a multi-dimensional adjustable support base includes a fixed base 3, a translation module, a first inclined block 8, a second inclined block 20, and a third inclined block 22. The translation module is connected to the fixed base 3 and is used for rolling translation in a first direction and a second direction. The second inclined block 20 and the third inclined block 22 are both connected to the side of the translation module away from the fixed base 3 and are closer to or further away from each other in the first or second direction. The first inclined block 8 is slidably connected to the translation module along the third direction, and the inclined surface of the first inclined block 8 is adapted to the inclined surface of the second inclined block 20 and the inclined surface of the third inclined block 22. The first and second directions are perpendicular to each other on the same horizontal plane, and the third direction is perpendicular to the first and second directions.

[0028] The fixed base 3 serves as the main load-bearing component of the entire adjustable support base. The upper part of the fixed base 3 is used to place and assemble the translation module, the first inclined block 8, the second inclined block 20, and the third inclined block 22. The lower part of the fixed base 3 is used to support the ground or workbench. A pad 2 is also connected to the lower part of the fixed base 3. The pad 2 is in close contact with the lower surface of the fixed base 3 to improve the load-bearing capacity of the fixed base 3. Expansion bolts 1 are provided around the fixed base 3 and the pad 2. The expansion bolts 1 are used to lock and fix the base and the pad 2 around the perimeter, and also to lock the required ground or workbench to improve the overall stability of the fixed base 3, so as to prevent positional displacement between the fixed base 3 and the ground or workbench, which would cause positional deviation and affect the subsequent adjustment accuracy.

[0029] The translation module is mounted on the fixed base 3 and can move horizontally in the first and second directions to adjust its position in two directions on a horizontal plane. Several spheres can be arranged on the side of the translation module facing the fixed base 3, allowing the module to roll directly onto the fixed base 3 to adjust its position in the first and second directions. Alternatively, to improve the adjustment accuracy of the translation module, it can be divided into two layers. The lower layer contacts the fixed base 3, allowing for back-and-forth adjustment in either the first or second direction, while the upper layer directly contacts the lower layer, allowing for back-and-forth adjustment in either the second or first direction. This layered layout allows for independent adjustment of the two layers, decoupling the control of the first and second directions to prevent interference during adjustment.

[0030] The first inclined block 8, the second inclined block 20, and the third inclined block 22 are all connected above the translation module. They move synchronously with the translation module as it is adjusted in the first and second directions. The second inclined block 20 and the third inclined block 22 are slidably connected to the upper surface of the translation module, preferably slidably disposed within a groove opened in the translation module, to limit the sliding range of the second inclined block 20 and the third inclined block 22, so as not to exceed the range required for adjustment of the second inclined block 20 and the third inclined block 22, and also to limit the adjustment process of the two. The first inclined block 8 is disposed above the second inclined block 20 and the third inclined block 22. The first inclined block 8 is preferably slidably connected in a vertical manner, that is, in this application, the first inclined block 8 is slidably connected to the translation module in the vertical direction, so that the first inclined block 8 slides smoothly above the translation module according to a preset trajectory.

[0031] When the second inclined block 20 and the third inclined block 22 approach each other, they cooperate with the inclined surface of the first inclined block 8 through their own inclined surfaces, so that the first inclined block 8 slides smoothly upward along the third direction, thereby achieving high-precision upward adjustment, and the second inclined block 20 and the third inclined block 22 evenly bear the weight of the first inclined block 8; when the second inclined block 20 and the third inclined block 22 move away from each other, they gradually move towards the end of the first inclined block 8 through their own inclined surfaces, so that the first inclined block 8 slides smoothly downward along the third direction, thereby achieving high-precision downward adjustment.

[0032] In this embodiment, the first inclined block 8, the second inclined block 20, and the third inclined block 22 are preferably all wedge-shaped blocks, and they contact each other through the inclined surfaces of the wedge-shaped blocks, so that the second inclined block 20 and the third inclined block 22 equally share the weight of the first inclined block 8. During the support process of the second inclined block 20 and the third inclined block 22, we assume that the inclination angle of the inclined surface of the wedge-shaped block is θ, the static friction coefficient is μ, and the weight of the first inclined block 8 and the subsequent oscillator foot is denoted as m. Considering the self-locking condition of the adjustable support base, the formula is as follows: ; According to the formula, the frictional force must be greater than the component of gravity in order to achieve the self-locking function of the first inclined block 8. Therefore, the first inclined block 8, the second inclined block 20, and the third inclined block 22 are all selected with the above-mentioned tilt angle θ.

[0033] In this embodiment, the first direction is preferably the length direction of the fixed base 3, such as... Figure 1 The middle direction is denoted as the X-axis, and the second direction is the width direction of the fixed base 3, as shown below. Figure 1 The Y-axis, denoted as [Y-axis], is preferably a direction perpendicular to the surface of the fixed base 3, such as [Y-axis]. Figure 1 The Z-axis is denoted as .

[0034] like Figure 1 and Figure 3As shown, the inclined surfaces of the first inclined block 8 facing the second inclined block 20 and the third inclined block 22 are V-shaped, and the inclined surfaces of the first inclined block 8 abut against the inclined surfaces of the second inclined block 20 and the third inclined block 22, respectively. The first inclined block 8 is a single unit. Figure 3 From the cross-section, the lower inclined surface is V-shaped, forming the second inclined block 20 and the third inclined block 22 to jointly support the first inclined block 8 at both ends of the X-axis, thereby maintaining the force balance during the entire support process of the first inclined block 8; when the second inclined block 20 and the third inclined block 22 approach each other at the same time, they compress the V-shaped inclined surface of the first inclined block 8, causing the first inclined block 8 to gradually move along the Z-axis, thereby achieving height stability adjustment.

[0035] Furthermore, such as Figure 2 , Figure 3 and Figure 5 As shown, a centering screw 21 is connected to the side of the translation module facing the first inclined block 8; the centering screw 21 is parallel to the third direction, passes through the first inclined block 8, and is slidably connected to the first inclined block 8.

[0036] The centering screw 21 is locked and fixed above the translation module and is located in the center position. The centering screw 21 can be threaded onto the translation module. Its outer wall runs through the entire first inclined block 8, and the middle part of the first inclined block 8 is also reserved to accommodate the centering screw 21, so that the centering screw 21 can restrict the sliding of the first inclined block 8 along the Z-axis direction and ensure the stability of the first inclined block 8 during the sliding process. In addition, the centering screw 21 can also be directly integrated with the upper surface of the translation module to reduce the positional offset of the centering screw 21.

[0037] To improve the support capacity of the first inclined block 8 for the foot, a spherical washer 9 is provided at the end of the first inclined block 8 away from the second inclined block 20 and the third inclined block 22. The spherical washer 9 is sleeved on the end of the centering screw 21 and is used to support the foot. The upper surface of the first inclined block 8 has a spherical groove, so that the spherical washer 9 can be perfectly accommodated in the entire spherical groove, improving the fitting accuracy between the spherical washer 9 and the first inclined block 8. Moreover, the spherical washer 9 can adapt to the support surface to ensure the installation level of the oscillator, thereby compensating for the levelness error of the ground.

[0038] Furthermore, such as Figures 1 to 5 As shown, the end of the centering screw 21 away from the translation module is connected to the positioning screw 11; the end of the positioning screw 11 away from the centering screw 21 is connected to the round washer 12; the round washer 12 and the spherical washer 9 are used to lock the foot onto the first inclined block 8.

[0039] After the centering screw 21 is installed, a positioning screw 11 is connected to the top of the centering screw 21. The end of the positioning screw 11 is locked onto the centering screw 21 by threads. A round washer 12 is independently fitted on the top of the positioning screw 11. An open washer 10 can also be fitted separately on the top of the spherical washer 9, so that a space for locking the foot is formed between the open washer 10 and the round washer 12. In order to prevent the round washer 12 from falling off from above and to improve the locking strength of the foot, the diameter of the middle part of the positioning screw 11 is larger than the diameter of the two ends. When the positioning screw 11 passes through the entire foot, the open washer 10 and the round washer 12 lock the bottom and top sides of the foot respectively, ensuring that the foot can be stably connected to the first inclined block 8 and move synchronously with the first inclined block 8.

[0040] like Figures 2 to 5 As shown, the translation module is also provided with a movable adjustment block 19, a guide tube 23, and a first adjustment screw 5; the movable adjustment block 19 is slidably connected to the translation module and is located on the side of the second inclined block 20 away from the third inclined block 22; one end of the guide tube 23 is connected to the movable adjustment block 19, and the other end of the guide tube 23 is connected to the second inclined block 20; the first adjustment screw 5 is rotatably mounted on the translation module, and the middle and end of the first adjustment screw 5 are respectively provided with opposite threads, which respectively drive the movable adjustment block 19 and the second inclined block 20 to move closer or further away from each other.

[0041] The movable adjustment block 19 slides back and forth following the translation direction of the second inclined block 20 and the third inclined block 22. When the translation direction of the second inclined block 20 and the third inclined block 22 is the first direction, the movable adjustment block 19 also slides along the first direction on the translation module; when the translation direction of the second inclined block 20 and the third inclined block 22 is the second direction, the movable adjustment block 19 also slides along the second direction on the translation module, depending on the situation; the guide tube 23 is used to connect the movable adjustment block 19 and the third inclined block 22 as a whole, so that the movable adjustment block 19 can drive the third inclined block 22 to move synchronously through the guide tube 23. This application has advantages. Two sets of guide tubes 23 are set, and the two sets of guide tubes 23 are respectively set on both sides of the centering screw 21 to avoid the position of the centering screw 21 and avoid interference. The guide tube 23 is equipped with a fixing screw 24 inside, and the guide tube 23 is sleeved on the outside of the fixing screw 24. The two ends of the fixing screw 24 are respectively threaded and locked on the third inclined block 22 and the moving adjustment block 19, thereby ensuring that the moving adjustment block 19 and the third inclined block 22 move synchronously. A space is opened on the second inclined block 20 for the guide tube 23 and the fixing screw 24 to pass through, so as to prevent the guide tube 23 and the fixing screw 24 from touching the second inclined block 20 and thus affecting the accuracy.

[0042] like Figures 1 to 6As shown, the translation module includes a sandwich plate 17 and a movable base plate 4; the sandwich plate 17 is disposed between the fixed base 3 and the movable base plate 4, a first roller group 18 is disposed between the sandwich plate 17 and the fixed base 3, and / or a second roller group 25 is disposed between the sandwich plate 17 and the movable base plate 4; the second inclined block 20 and the third inclined block 22 are slidably connected to the movable base plate 4 in a first direction or a second direction.

[0043] The mezzanine plate 17 serves as the main translational carrier, and roller assemblies can be installed on its upper and / or lower sides. Since both the first roller assembly 18 and the second roller assembly 25 are spherical, roller assemblies only need to be installed on the upper or lower side of the mezzanine plate 17, or they can be installed on both sides. The movable base plate 4 serves as the main load-bearing plate, and a groove is provided on its upper surface to accommodate the second inclined block 20 and the third inclined block 22, thus restricting their movement. The weight of the movable base plate 4 is applied to the mezzanine plate 17, and the upper surface of the movable base plate 4 is directly locked to the centering screw 21. Figure 3 As shown, a first fixed block 6 is integrally provided at one end of the movable base plate 4. A first adjusting screw 5 is rotatably connected to the first fixed block 6. The middle and end of the first adjusting screw 5 are provided with opposite spiral lines, so that when the first adjusting screw 5 rotates, it can synchronously drive the movable adjusting block 19 and the second inclined block 20 to move closer or further apart, thereby realizing that the second inclined block 20 and the third inclined block 22 jointly squeeze the V-shaped inclined surface of the first inclined block 8, thereby realizing the height adjustment of the first inclined block 8, and realizing self-locking through static friction. The whole process does not require the tooth surface of the worm gear to achieve self-locking, which greatly reduces the wear of self-locking and improves the service life. At the same time, the use of roller group to achieve translation, and through the height adjustment of the first inclined block 8, the second inclined block 20 and the third inclined block 22, the internal size is greatly reduced.

[0044] Based on this embodiment, since the second inclined block 20 can sink into the groove opened in the movable base plate 4, the height of the adjustable base in the third direction can be further reduced. In addition, the weight of the foot can be supported on the centering screw 21, and can also be distributed to the second inclined block 20 and the third inclined block 22 through the first inclined block 8, so that the force is applied to three parallel fulcrums in the third direction, which greatly improves the stability and reliability of the support. At the same time, it avoids the first adjusting screw 5 from continuously maintaining a self-locking state. Self-locking can be achieved by relying only on the surface friction between the first inclined block 8 and the second inclined block 20, and between the first inclined block 8 and the third inclined block 22, without the need to add an additional self-locking mechanism, thus keeping the overall structure more compact.

[0045] like Figure 6As shown, the first roller group 18 consists of several first cylindrical rollers, the axes of which are parallel to the second direction; the second roller group 25 consists of several second cylindrical rollers, the axes of which are parallel to the first direction.

[0046] Based on the above embodiments, this embodiment preferably provides roller groups on both the upper and lower sides of the sandwich plate 17. Therefore, in order to achieve decoupling of the adjustment in the first direction and the second direction, this embodiment provides several first cylindrical rollers below the sandwich plate 17 and several second cylindrical rollers above the sandwich plate 17. The first cylindrical rollers and the second cylindrical rollers can respectively drive the sandwich plate 17 to translate in the first direction and the second direction, so as to avoid interference between the adjustment in different directions.

[0047] The axes of several first cylindrical rollers are parallel to the second direction, so that when the first rollers are placed under the sandwich plate 17, they can reduce the friction of the sandwich plate 17 by rolling, thereby driving the position of the movable base plate 4, the first inclined block 8, the second inclined block 20 and the third inclined block 22 above the sandwich plate 17; the movable base plate 4 is placed under several second rollers, the axes of which are parallel to the first direction, so that the movable base plate 4 can be adjusted in position along the second direction under the drive of external force, thereby driving the first inclined block 8, the second inclined block 20 and the third inclined block 22 to move synchronously.

[0048] During the adjustment of the translation module, the fixed base 3 is provided with a second fixed block 13, a second adjusting screw 14, a third fixed block 16, and a third adjusting screw 15 at both ends of the first and second directions, respectively. The second adjusting screw 14 is rotatably connected to the second fixed block 13. When an external force drives the mezzanine plate 17 to move along the first direction, the second adjusting screw 14 at both ends of the fixed base 3 will gradually abut against the mezzanine plate 17 or the movable base plate 4, thereby limiting the position of the translation module on the X-axis. Similarly, the third adjusting screw 15 is rotatably connected to the third fixed block 16. When an external force drives the movable base plate 4 to move along the Y-axis, the third adjusting screw 15 at both ends of the fixed base 3 will gradually abut against the movable base plate 4, ultimately fixing the position on the Y-axis.

[0049] Furthermore, such as Figure 3 , Figure 5 and Figure 6 As shown, a plurality of first cylindrical rollers are disposed on the fixed base 3; a plurality of second cylindrical rollers are disposed on the sandwich plate 17; and the movable base plate 4 has flanges extending to both ends of the sandwich plate 17 in a first direction.

[0050] The first cylindrical roller can be positioned below the sandwich plate 17. In this application, it is preferred that the first cylindrical roller be positioned directly on the fixed base 3. Similarly, the second cylindrical roller can be positioned below the movable base plate 4. In this application, it is preferred that the second cylindrical roller be positioned above the sandwich plate 17, thereby maintaining the thickness of the movable base plate 4 so as not to weaken the load-bearing capacity of the movable base plate 4.

[0051] Based on the above embodiments, this application also includes a housing 7, which is fitted over the entire movable base plate 4 and covers the first adjusting screw 5, thereby protecting the internal transmission components.

[0052] This application also discloses an oscillator having multiple feet, each foot being placed on the first inclined block 8 of the aforementioned multidimensional adjustable support base.

[0053] The adjustable support base of this application presses the first inclined block 8 by the second inclined block 20 and the third inclined block 22, so that the first inclined block 8 can be raised and lowered stably. At the same time, it can achieve self-locking by relying on the friction between the first inclined block 8 and the second inclined block 20, and between the first inclined block 8 and the third inclined block 22. No additional self-locking mechanism is required, and stress contact wear between the worm gear is avoided, which greatly improves the service life. At the same time, while ensuring the compact structure of the adjustable support base, it can also support the feet of heavy oscillators.

[0054] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application.
