Description

Technical Field

[0001] The utility model relates to the technical field of precision operating platforms, in particular to a fully flexible high-precision posture adjustment combined platform. Background Art

[0002] The posture adjustment mechanism is a key component of the precision optical platform. The existing method is mainly to achieve posture adjustment through a rigid block supported by a steel ball or pin, and a spring and a fine-thread set screw. However, neither the spring rebound nor the fine-thread set screw can withstand large loads, so it can only be used in light load situations, and the application scenarios are limited. In addition, the combination of multiple parts makes manufacturing and assembly complicated.

[0003] A flexible hinge structure with adjustable deflection angle, with a prior art application number of 202311111656.6, proposes a flexible hinge mechanism to replace the rigid mechanism. It has a compact structure and is locked with high rigidity by combining a set screw and a tension bolt. However, the set screw and the tension bolt are mutually exclusive. When adjusting, the set screw needs to be loosened first, and then the deflection angle of the flexible hinge can be adjusted by the tension bolt. The operation is more troublesome and prone to damage. In addition, the structure also has a contradiction between stiffness and precision, that is: when coarse-thread screws are used, the stiffness is large, but the precision is low; when fine-thread screws are used, the precision is high, but the stiffness is small and the load capacity is poor. In addition, there is redundancy during adjustment, the logic is complex, and it is difficult to achieve electric adjustment.

[0004] A further prior art application number 202410368918.5 proposes a flexible hinge posture high-precision adjustment platform, which adopts a composition mechanism consisting of two rotating parts (double live bolts or double bolts + steering structure) and a moving part to form an adjustment pair (differential bolt), solving the contradiction between high-precision adjustment and bearing capacity. The double rotating part solution realizes the adjustment of the deflection angle by the opening length, and the single adjustment bolt is easy to adjust and can also be easily changed to electric adjustment.

[0005] However, there is a contradiction between the clearance and friction in the swing bolt or the pin shaft rotation pair. During operation, it is necessary to lock it to eliminate the clearance and ensure rotation. The tighter the lock, the greater the friction, which will affect the adjustment. In addition, the angle and distance change during the adjustment process, so that the motor can only be fixed on the swing bolt rod, which is inconvenient to install and relatively costly. Utility Model Content

[0006] The purpose of the utility model is to provide a fully flexible high-precision posture adjustment combined platform to solve the problems raised in the above background technology, namely, the tighter the lock, the greater the friction, the adjustment will be affected by the friction, and the motor is inconvenient to install and the cost is high.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] The fully flexible and high-precision posture adjustment combined platform proposed in the utility model is composed of at least one group of notch-type flexible hinges, one side of the notch-type flexible hinge has an opening, and two nuts are arranged on one side of the opening. The two nuts are connected by a double-threaded adjustment component to adjust the thickness and / or angle of the notch-type flexible hinge. The utility model also includes a connecting part located on the other side of the notch-type flexible hinge; an elastic deformation rotating part between the notch-type flexible hinge and the nut to eliminate the friction effect during the thickness and / or angle adjustment and the gap between the nut and the double-threaded adjustment component.

[0009] Optionally, when the number of the notched flexible hinges is greater than one group, adjacent notched flexible hinges are orthogonally connected or vertically connected along their thickness direction to adjust the verticality and / or deflection angle of the adjusted device.

[0010] Optionally, the connecting part is a rigid block or a first piece flexible hinge, and the rigid block is integrally formed with the cut-out flexible hinge; the first piece flexible hinge is vertically and detachably mounted on one side of the cut-out flexible hinge, so that the cut-out flexible hinge forms a U-shaped open structure.

[0011] Optionally, the elastic deformation rotating part is a rotating block with upper and lower notches, and the center position of the rotating block serves as the torsion center when the notch-type flexible hinge is deformed.

[0012] Optionally, the notch-type flexible hinge, nut and rotating block are integrally formed.

[0013] Optionally, the elastic deformation rotating part is a second piece-type flexible hinge, and the second piece-type flexible hinge is detachably connected between the notch-type flexible hinge and the nut along the length direction of the notch-type flexible hinge.

[0014] Optionally, the double-thread adjustment assembly includes an integrally formed first bolt and a second bolt, wherein the first bolt and the second bolt have the same rotation direction and different thread pitches, and the first bolt and the second bolt are correspondingly mounted in conjunction with two nuts.

[0015] Optionally, the diameter of the first bolt is greater than the diameter of the second bolt, and a driving member is installed at one end of the first bolt.

[0016] Optionally, a motor is further included, and a gear is installed at the output end of the motor, and the gear cooperates with the driving member.

[0017] The fully flexible high-precision posture adjustment combined platform is applied in large-format detection equipment, large-format manufacturing equipment, vertical operation equipment with height deviation or optical precision measurement field.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. On the basis of the angle adjustment of the flexible hinge, the utility model adds a rotatable elastic deformation part between the notched flexible hinge and the nut to achieve full flexible adjustment and eliminate the friction effect of the double-threaded adjustment component during adjustment movement.

[0020] 2. The double bolts of the double-threaded adjustment assembly use stepped bolts with different pitches, and the end with the larger diameter is processed with a handwheel or gear to facilitate manual or automatic adjustment.

[0021] 3. The detachable second-piece flexible hinge design can increase the bolt adjustment range and adapt to different adjustment strokes to achieve a wide range of adjustment; at the same time, it is easy to replace nuts with different pitches to further adapt to different adjustment accuracy and stroke.

[0022] 4. By utilizing a double flexible rotating mechanism composed of a connecting part and a rotating part, during the adjustment process, the posture and horizontal position of the nut adapt to the deformation of the notched flexible hinge but remain unchanged. On the one hand, it is beneficial to the installation of the motor and realizes the purpose of automatic adjustment. On the other hand, it reduces the number of intermediate connecting parts and only requires one rotating part. The structure is simple, avoids the friction caused by multiple parts, and greatly reduces the cost.

[0023] 5. The rotating part adopts a certain rigidity elastic body to bend and deform to realize the rotating mechanism. When the double bolts are adjusted, a torsional moment is generated, which stretches the double bolts up and down respectively to eliminate the gap between the bolts and nuts.

[0024] 6. The method of the utility model solves the drawbacks of the traditional optical adjustment platform, such as the large number of components, poor stability, over-constraint and complex adjustment of the bolt and set screw combination adjustment of the flexible hinge mechanism.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0047] Embodiment 1

[0048] See also Figure 1 The utility model provides a fully flexible high-precision posture adjustment combined platform, which is composed of a group of cut-out flexible hinges 1 and adopts a manual adjustment method.

[0049] In this embodiment, one side of the notch-type flexible hinge 1 has an opening 11, which is located in the middle of the notch-type flexible hinge 1 and is arranged along one side of its length direction, and the opening 11 can be retracted to adjust the angle of the notch-type flexible hinge 1. Two nuts 2 are arranged on one side of the opening 11, and the two nuts 2 are connected by a double-threaded adjustment component 3 to adjust the thickness and angle of the notch-type flexible hinge 1.

[0050] The adjustment platform also includes a connection portion located at the other side of the notch-type flexible hinge 1. The connection portion is a rigid block 12, and the rigid block 12 and the notch-type flexible hinge 1 are integrally formed and manufactured.

[0051] Furthermore, the adjustment platform also includes an elastically deformable rotating part between the notched flexible hinge 1 and the nut 2 to eliminate the friction effect during thickness and angle adjustment and the gap between the nut and the bolt. The rotating part is a rotating block 51 with upper and lower notches. The center position of the rotating block 51 serves as the torsion center when the notched flexible hinge 1 is deformed. The rotating block 51 can also be integrally formed with the notched flexible hinge 1 and the nut 2. During the adjustment process, the posture and relative position of the nut 2 and the double-threaded adjustment component 3 remain unchanged to adapt to the deformation of the notched flexible hinge 1. The rotating block 51 serves as a rotatable buffer to achieve full flexible adjustment and eliminate the friction effect of the double-threaded adjustment component 3 during adjustment movement.

[0052] Specifically, the double-threaded adjustment assembly 3 uses an adjustment pair formed by two rotating parts and one moving part, the two rotating parts are two rotating blocks 51, and the moving part is composed of two first bolts 31 and second bolts 32 with the same rotation direction and different pitches. The first bolt 31 and the second bolt 32 are correspondingly mounted to the two nuts 2, and the diameter of the first bolt 31 is larger than the diameter of the second bolt 32. During the initial installation and screwing process, pressure is first applied to adjust the notched flexible hinge 1 to the minimum position of the opening 11. As the spiral is screwed in, the opening 11 slowly increases until the large bolt-the first bolt 31 reaches the entrance of the small nut-the second bolt 32.

[0053] A driving member 4 is installed at one end of the first bolt 31 . The driving member 4 may be a hand wheel or a gear, and an outer surface thereof may be provided with an anti-skid thread (to increase friction during manual adjustment) or a smooth surface.

[0054] When coarse-thread bolts are required, the first bolt 31 can be a bolt with a pitch of M6 0.8, and the second bolt 32 can be a bolt with a pitch of M5 0.7. By utilizing a differential pull rod structure, two bolts with the same rotation direction but different pitches are simultaneously connected with two nuts 2 to change the spacing between the two nuts 2. For each rotation of the bolt, the adjustment distance is 0.1 of the pitch difference, which not only achieves precise adjustment but also ensures the strength of the thread. At the same time, a torsional torque is generated during the adjustment of the double bolts, which stretches the double bolts up and down respectively to eliminate the gap between the bolts and the nuts.

[0055] It is worth noting that the adjustment stroke s is calculated as the number of turns n*(bolt pitch difference) of the large bolt-first bolt 31, and the adjustment angle range (in radians) is the adjustment stroke divided by the distance d from the center axis of the bolt to the rotation center of the rotating part, such as Figure 1 The shortest straight-line distance from the bolt marked in to the rotating block 51.

[0056] When the driving member 4 is rotated, the first bolt 31 and the second bolt 32 are restricted from rotating along the axial direction of the rotating shaft 14 under the action of the thread force. Therefore, the first bolt 31 and the second bolt 32 synchronously undergo linear displacement in the same direction, and the displacement distance is the difference in the pitch of the two bolts, thereby further achieving the purpose of angle adjustment of the fully flexible and high-precision posture adjustment combined platform.

[0057] Embodiment 2

[0058] Reference Figure 3 Compared with the first embodiment, the fully flexible high-precision posture adjustment combination platform of this embodiment adopts a set of cut-out flexible hinges with a structure of a rigid block 12 + a second-piece flexible hinge 52, replaces the two rotating blocks 51 with two second-piece flexible hinges 52, and adopts manual adjustment.

[0059] The second piece flexible hinge 52 can be glued or clamped between the nut 2 and the notch flexible hinge 1 by interference fit, or by drilling holes in the nut 2 and the notch flexible hinge 1 and pressing down the positioning pin from the hole to fix the position of the second piece flexible hinge 52. Regardless of the method, the main purpose is to achieve the replaceable nut 2 and the double-threaded adjustment assembly 3, which can increase the double-bolt adjustment range and facilitate the replacement of nuts with different pitches to further adapt to different adjustment strokes.

[0060] Embodiment 3

[0061] Reference Figure 4 Compared with the first or second embodiment, the fully flexible high-precision posture adjustment combination platform of this embodiment adopts a set of cut-out flexible hinges having a structure of a first-piece flexible hinge 13 + a second-piece flexible hinge 52, and replaces the rigid block 12 and the two rotating blocks 51 with sheet-type flexible hinges respectively, and adopts manual adjustment.

[0062] The first piece flexible hinge 13 is vertically detachably mounted on one side of the notch-type flexible hinge 1, so that the notch-type flexible hinge 1 forms a U-shaped opening structure. The first piece flexible hinge 13 can be glued or clamped on one side of the notch-type flexible hinge 1 by interference fit, or by opening a hole on the side of the notch-type flexible hinge 1 and pressing a positioning pin from the hole to fix the position of the first piece flexible hinge 13. Regardless of the method, the main purpose is to achieve replacement of flexible hinges of different thicknesses, adapt to different adjustment strokes, and achieve a wide range of adjustment.

[0063] Embodiment 4

[0064] Reference Figure 5 Compared with the first embodiment, the second embodiment or the third embodiment, the fully flexible high-precision posture adjustment combined platform of this embodiment adopts two sets of notched flexible hinges 1 structures, and the adjacent notched flexible hinges 1 are orthogonally connected along their thickness direction (such as Figure 5-Figure 8 ) or vertical connection (such as Figure 9-11 ), adjust the verticality and deflection angle of the adjusted equipment, and use manual adjustment method.

[0065] When the number of the notch-type flexible hinges 1 is greater than one group, multiple groups of notch-type flexible hinges 1 are arranged and connected along the thickness direction thereof, and adjacent flexible hinges share a portion of the same flexible hinge (except for the rigid block 12), so that multiple groups of notch-type flexible hinges 1 are combined and connected in an orthogonal manner, and adjacent double-threaded adjustment components 3 are located in different directions of the notch-type flexible hinges 1. In this embodiment, two groups of double-threaded adjustment components 3 are used, wherein the opening 11 of one group of notch-type flexible hinges 1 is arranged in the left or right direction, and the opening 11 of the other group of notch-type flexible hinges 1 is arranged in the front or rear direction, and the actual direction of the opening 11 shall prevail.

[0066] Furthermore, when two groups of notch-type flexible hinges 1 or more than two groups of notch-type flexible hinges 1 are used in combination, the connecting part and the rotating part are combined in a random assembly manner according to actual needs, for example: rigid block 12+rotating block 51; rigid block 12+second-piece flexible hinge 52; first-piece flexible hinge 13+rotating block 51; first-piece flexible hinge 13+second-piece flexible hinge 52.

[0067] The adjustment method is the same as that of the first embodiment: the driving member 4 is rotated separately. Under the action of the thread, the first bolt 31 and the second bolt 32 are restricted from rotating along the axial direction of the rotating shaft 14. Therefore, the first bolt 31 and the second bolt 32 are synchronously displaced linearly in the same direction. The displacement distance is the difference in the pitch of the two bolts, further achieving the purpose of angle adjustment of the fully flexible high-precision posture adjustment combined platform.

[0068] Embodiment 5

[0069] like Figure 2 As shown, based on Example 1, Example 2, Example 3 or Example 4, the fully flexible high-precision posture adjustment combination platform of the utility model is composed of one or two groups of notch-type flexible hinges 1, and its composition structure is the same as that of the aforementioned Example 1, Example 2, Example 3 or Example 4, and adopts an electric adjustment method.

[0070] The electric adjustment mechanism mainly includes a motor 6, and a gear 7 is installed at the output end of the motor 6. The gear 7 cooperates with the driving member 4. When the two cooperate, the driving member 4 also uses other gear accessories that mesh with the gear 7 to drive the first bolt 31 and the second bolt 32 to rotate synchronously, and then the purpose of adjusting the angle of the fully flexible high-precision posture adjustment combined platform is achieved in the same manner as the above-mentioned adjustment method.

[0071] It is worth noting that in this embodiment, the motor 6 is installed on the outer end surface of one of the nuts 2, and a double flexible rotating mechanism composed of a connecting part and a rotating part is utilized. During the adjustment process, the posture and horizontal position of the nut 2 adapt to the deformation of the notched flexible hinge 1 but remain unchanged. On the one hand, it is convenient for the installation of the motor 6 to achieve the purpose of automatic adjustment; on the other hand, it reduces the number of intermediate connecting components, and only one rotating part is required to achieve it, so the structure is simple, avoiding the friction caused by multiple components, and greatly reducing costs.

[0072] Embodiment 6

[0073] like Figure 6-Figure 8On the basis of the fifth embodiment, the fully flexible high-precision posture adjustment combined platform of this embodiment is assembled by a group of notched flexible hinges 1 or two groups of notched flexible hinges 1 in an orthogonal manner, and also includes an optical lens and a connecting flange. The optical lens penetrates along the thickness direction of the notched flexible hinge 1. The connecting flange can be an annular sleeve on the outside of the optical lens, or a C-shaped structure that half surrounds the optical lens. A group of bolts is provided at the opening of the C-shaped structure to clamp and fix the optical lens, so as to realize the fixed connection of the optical lens, the connecting flange and the notched flexible hinge 1. This group of structures is simple, and solves the problems of the traditional optical adjustment platform having many components and poor stability, as well as the drawbacks of over-constraint and complex adjustment of the bolt and set screw combination adjustment in the flexible hinge mechanism.

[0074] Embodiment 7

[0075] like Figure 9-11 Compared with the sixth embodiment, the fully flexible high-precision posture adjustment combined platform of this embodiment is assembled by a set of cut-out flexible hinges 1 or two sets of cut-out flexible hinges 1 connected vertically. When two sets of cut-out flexible hinges 1 are used in combination, one set of cut-out flexible hinges 1 is located at the bottom of the optical lens to adjust the height of the upper and lower positions of the optical lens. The other set of cut-out flexible hinges 1 is perpendicular to the upper side of the bottom cut-out flexible hinge 1, and its opening 11 is parallel to the optical lens. The front and rear positions of the optical lens are adjusted by the same double-threaded adjustment component 3.

[0076] In all the above embodiments, whether the adjustment is performed manually or electrically, the adjustment mechanism is the same, and the optical lens and the connecting flange can be assembled to adjust the verticality of the lens, or to adjust the up and down, left and right positions of the optical lens.

[0077] In all the above embodiments, when applied to optical precision measurement, the optical lens and the object to be measured are required to always maintain a 90° verticality to ensure that the image is not distorted and the accuracy of the detection results. When a fully flexible high-precision posture adjustment combination platform with a set of notched flexible hinges 1 is used, the left and right deflection angle of the optical lens can be adjusted; when using a fully flexible high-precision posture adjustment combination platform with two sets of notched flexible hinges 1 in different directions as in Example 6, the left and right deflection angle or the front and rear pitch angle of the optical lens can be adjusted at the same time, which has a wider range of applications and can also be used in other precision measurement or operation platforms for mechanical processing. It has fewer components, a simple structure, low cost, and higher stability.

[0078] In addition to the field of optical precision measurement, the fully flexible high-precision posture adjustment combined platform of the utility model can also be used in large-format detection equipment (such as probe stations), large-format manufacturing equipment (such as large-panel needle crystals), and vertical operation equipment with height deviation (such as dispensing equipment).

[0079] In the above content, the exemplary implementation of the scheme proposed by the utility model is described in detail with reference to the preferred embodiments. However, it can be understood by those skilled in the art that, without departing from the concept of the utility model, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed by the utility model can be combined in various ways without exceeding the protection scope of the utility model, which is determined by the attached claims.
