Description

Technical Field

[0001] This invention relates to the field of mechanical adjustment devices, and in particular to a two-dimensional adjustment device. Background Technology

[0002] During the installation and commissioning of equipment such as optical instruments, monitoring sensors, and laser terminals, two-dimensional adjustment devices are usually required to achieve pitch and horizontal attitude adjustment.

[0003] Existing two-dimensional adjustment devices mostly employ transmission components such as worm gears and precision bearings to achieve high-precision angle control. For example, Chinese patent application number CN202521145485.3 discloses "A Two-Dimensional Attitude Adjustment Device Using a Worm Gear Structure," which includes a pitch rotation component, a roll rotation component, a rotating platform, a pitch manual adjustment component, a roll manual adjustment component, a pitch locking screw, and a roll locking screw. By rotating the pitch manual adjustment component, the roll rotation component is made to pitch around a first pitch axis and a second pitch axis. Since the rotating platform is mounted on the roll rotation component, it also pitches and rotates with the roll rotation component, realizing the adjustment of pitch freedom. When the corresponding pitch adjustment position is reached, the pitch locking screw is tightened for fixation. Then, by rotating the roll manual adjustment component, the rotating platform is made to roll around a first roll axis and a second roll axis, realizing the adjustment of roll freedom. When the corresponding roll adjustment position is reached, the roll locking screw is tightened for fixation. This method is convenient to adjust, reduces costs, and improves economy.

[0004] However, in outdoor working environments, due to harsh factors such as moisture, dust, temperature changes, and vibration, the worm gears in the aforementioned patents are prone to internal corrosion, jamming, or wear, leading to adjustment failure or decreased accuracy, failing to meet the usage requirements of outdoor working environments, and are also expensive.

[0019] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] This invention provides a two-dimensional adjustment device, see below. Figures 1 to 6 , Figure 1 This is a schematic diagram of the structure of the two-dimensional adjustment device provided by the present invention; Figure 2 This is a schematic diagram of the structure of the bearing module in the two-dimensional adjustment device provided by the present invention; Figure 3 This is a schematic diagram of the pitch sliding table in the two-dimensional adjustment device provided by the present invention; Figure 4 This is a schematic diagram of the structure of the horizontal rotary table in the two-dimensional adjustment device provided by the present invention; Figure 5 This is a schematic diagram of the pitch adjustment module in the two-dimensional adjustment device provided by the present invention; Figure 6 This is a schematic diagram of the horizontal adjustment module in the two-dimensional adjustment device provided by the present invention.

[0021] The two-dimensional adjustment device provided in this embodiment of the invention includes a support platform 110, a pitch sliding table 120 disposed on the support platform 110, and a horizontal rotary table 130 disposed on the pitch sliding table 120; the pitch sliding table 120 is in surface contact and sliding engagement with the support platform 110, and the horizontal rotary table 130 is in rotational engagement with the surface of the pitch sliding table 120 around an axis; the support platform 110 is connected to a support base 210, the support base 210 is threadedly connected to a pitch adjusting rod 220, one end of the pitch adjusting rod 220 is in a transmission connection with the pitch sliding table 120; the pitch sliding table 120 is connected to a fixed base 310, the fixed base 310 has a receiving area 311, a top block 320 connected to the horizontal rotary table 130 is disposed in the receiving area 311, and a horizontal adjusting rod 330 abuts against each side of the top block 320, the horizontal adjusting rod 330 being threadedly connected to the fixed base 310.

[0022] In this embodiment, the support platform 110 serves as the mounting reference and can be connected to an external tripod or mounting panel via bolts or other fasteners. The pitch slide stage 120 is fitted against the upper surface of the support platform 110, and the two slide relative to each other to achieve pitch angle adjustment. The horizontal rotary stage 130 is located above the pitch slide stage 120, and the two can rotate relative to each other around a vertical axis to achieve horizontal angle adjustment. The horizontal rotary stage 130 is used to support optical instruments, sensors, and other adjustment equipment.

[0023] Specifically, the support base 210 is fixed to the side or bottom of the support platform 110. The pitch adjustment rod 220 passes through a threaded hole on the support base 210. When the pitch adjustment rod 220 is rotated, the helix angle of the threaded pair converts the rotational motion into linear feed motion, thereby pushing or pulling the pitch slide table 120 to tilt and slide relative to the support platform 110, achieving precise adjustment of the pitch angle and maintaining stable posture after adjustment. Optionally, the pitch adjustment rod 220 can adopt a fine thread design to improve adjustment resolution.

[0024] The fixed base 310 is mounted on the pitch sliding stage 120 and moves synchronously with it. The receiving area 311 of the fixed base 310 provides the top block 320 with a space for movement and a limiting reference. The top block 320 is fixedly connected to the horizontal rotary stage 130, transmitting the horizontal adjustment force to the horizontal rotary stage 130. Two horizontal adjustment rods 330 are screwed in from both sides of the fixed base 310 and abut against the sides of the top block 320. When the horizontal angle needs to be adjusted, rotating the horizontal adjustment rods 330 on both sides will push the top block 320 and the horizontal rotary stage 130 to rotate around the axis through the abutment force. This not only achieves stepless fine adjustment of the horizontal angle, but also, after adjustment, a rigid fixation can be formed by locking the horizontal adjustment rods 330 in opposite directions, effectively resisting angle drift caused by external vibration.

[0025] Optionally, the support platform 110 is made of one piece of aluminum alloy with an anodized surface. Its dimensions are 130mm×130mm×15.5mm. The base plate of the support platform 110 is flat, and the opening size around the base plate is compatible with a universal tripod panel for installation.

[0026] Thus, through the sliding engagement of the pitch sliding stage 120 and the bearing platform 110, and the rotational engagement of the horizontal rotary stage 130 and the pitch sliding stage 120, the present invention constructs a foundation for adjusting two mutually orthogonal degrees of freedom, and the realization of both degrees of freedom does not depend on precision transmission components.

[0027] To facilitate understanding of modularity, the two-dimensional adjustment device of this invention includes a support module 100, a pitch adjustment module 200, and a horizontal adjustment module 300. The support module 100 includes a support platform 110, a pitch sliding table 120, a horizontal rotary table 130, a clamping component 140, and a fixing pin 150. The pitch adjustment module 200 includes a support base 210, a pitch adjustment rod 220, and a cylindrical sliding block 230. The horizontal adjustment module 300 includes a fixed base 310, a top block 320, a horizontal adjustment rod 330, and a manual adjustment rod 340. Thus, this invention decouples the support, pitch, and horizontal adjustment modules 300 into independent detachable units through standardized quick-release interfaces, breaking the traditional pattern of integrated fixed structures for pitch and horizontal adjustment. This allows for individual module replacement in case of failure, eliminating the need for overall replacement and avoiding resource waste caused by complete scrapping. Furthermore, the pitch and horizontal adjustment modules 200 and 300 can be disassembled and reused on other turntables, significantly reducing the overall system cost. Furthermore, each module can be disassembled and stored independently, further reducing the storage volume and making it suitable for outdoor backpacks. All quick-release interfaces adopt a unified tolerance standard, ensuring high interchangeability, and the repeatability of each module's disassembly and assembly is ≤0.05°.

[0028] Please refer to it again. Figure 1 , Figure 2 and Figure 3 In some embodiments, the upper surface of the support platform 110 is a cylindrical surface, and the bottom surface of the pitch sliding table 120 is a cylindrical surface with the same radius.

[0029] Specifically, when the pitch adjustment rod 220 drives the pitch sliding table 120 to move, a large-area surface contact sliding pair is formed between the two cylindrical surfaces, allowing the pitch sliding table 120 to smoothly swing around the center of the sphere in multiple degrees of freedom. On the one hand, the spherical contact can evenly distribute the load across the entire mating surface, avoiding local stress concentration, thus achieving high load-bearing capacity in a lightweight structure; on the other hand, the open surface contact structure does not have precision rolling elements or closed gear cavities, completely eliminating the risk of internal corrosion and jamming caused by sand and moisture intrusion. Even after long-term use in harsh outdoor environments, performance can be restored simply by wiping, without the need for professional maintenance.

[0030] Optionally, the cylindrical surface is a standard machined cylindrical surface with a rated load ≥10KG and an ultimate load up to 25KG.

[0031] It should be understood that although a standard cylindrical surface is preferably used in this embodiment to achieve isotropic motion characteristics, in other embodiments, an ellipsoidal surface, a conical surface or other rotating surface may also be used, as long as it can provide stable surface contact support and allow the pitch sliding stage 120 to slide relative to the bearing platform 110 along a predetermined trajectory.

[0032] Please refer to it again. Figure 3 In some embodiments, a first slide groove 121 is provided on the side of the pitch slide table 120, and clamping members 140 are provided on both sides of the pitch slide table 120. Thread holes 141 are opened on the clamping members 140, and anti-detachment posts 143 are provided in the thread holes 141. The anti-detachment posts 143 extend into the first slide groove 121 and slide in cooperation with the first slide groove 121.

[0033] Specifically, the clamping member 140 is typically fixed to the support platform 110 by bolts, and together with the support platform 110, constrains the pitch sliding stage 120. The anti-detachment column 143 extends into the first slide groove 121 and cooperates with it. The first slide groove 121 restricts the movement trajectory of the pitch sliding stage 120, thereby preventing the pitch sliding stage 120 from rotating around the vertical axis, shifting laterally, or even falling off during adjustment, ensuring the accuracy of the pitch angle adjustment. Simultaneously, the clamping member 140 also serves as an anti-detachment device, ensuring that the pitch sliding stage 120 remains constrained to the support platform 110 even under extreme vibration or accidental impact conditions, preventing separation and detachment. Optionally, the anti-detachment column 143 can be made of wear-resistant stainless steel and surface-hardened to extend its service life; the shape of the first slide groove 121 can be a straight groove, an arc groove, or an oblong groove, depending on the required movement trajectory characteristics.

[0034] Preferably, the first slide groove 121 is machined by one-piece milling. The flatness of the contact surface of the first slide groove 121 used to fit the anti-detachment post 143 is ≤0.02mm. The anti-detachment post 143 is a grommet screw, and the threaded hole 141 is a grommet screw mounting hole. The flatness of the anti-detachment post 143 is ≤0.01mm, and the roughness is ≤0.8, to ensure smooth movement without jamming.

[0035] Please refer to it again. Figure 3 In some embodiments, the pitch sliding stage 120 is provided with a plurality of first limiting holes 122 on its side, the clamping member 140 is provided with a limiting groove 142, and the positioning post passes through the limiting groove 142 and is connected to the first limiting holes 122.

[0036] Specifically, when the pitch slide table 120 slides to the target angle, the operator passes the positioning pin through the limiting groove 142 on the clamping member 140 and inserts it into the corresponding first limiting hole 122. This physically prevents the pitch slide table 120 from continuing to slide along the spherical surface, effectively resisting angle drift caused by external wind loads, equipment weight, or transportation vibrations. The limiting groove 142 can be a long strip or an oblong hole, allowing the positioning pin to adjust its position within a certain range to adapt to the alignment requirements of different first limiting holes 122, reducing the alignment difficulty during assembly and operation. At the same time, the cooperation of the positioning pin, the limiting groove 142, and the first limiting hole 122 achieves self-locking of the pitch angle adjustment, preventing slight changes in the pitch angle under long-term outdoor disturbance environments.

[0037] Please refer to it again. Figure 2 In some embodiments, the number of limiting grooves 142 is at least two, each limiting groove 142 corresponds to a plurality of first limiting holes 122, and a support structure is provided between two adjacent limiting grooves 142.

[0038] Specifically, multiple limiting grooves 142 are spaced apart along the movement direction of the pitch sliding table 120, thus forming multiple discrete rigid locking points throughout the entire pitch adjustment range. During use, the locking point closest to the target angle can be selected for fixation according to actual needs, balancing the adjustment range and locking rigidity. The support structure between adjacent limiting grooves 142 can enhance the structural strength of the limiting grooves 142.

[0039] Please refer to it again. Figure 5 In some embodiments, one side of the pitch sliding stage 120 is connected to the cylindrical sliding block 230, the cylindrical sliding block 230 has a sliding groove 231, and one end of the pitch adjustment rod 220 is provided with a spherical sliding structure 221, which is embedded in the sliding groove 231.

[0040] Specifically, the cylindrical sliding block 230 is fixed to the side of the pitch sliding table 120 by screws, and the sliding groove 231 extends along the direction perpendicular to the axis of the pitch adjusting rod 220. Its cross-sectional shape is adapted to the outer contour of the spherical sliding structure 221, forming an inclusive kinematic pair. When the pitch adjusting rod 220 is rotated, the helix angle of the screw pushes the spherical sliding structure 221 at the end to move along the axial direction. Since the sliding structure 221 is constrained in the sliding groove 231, its linear displacement is forced to be decomposed into a sliding component along the groove length and a thrust component perpendicular to the groove surface. The vertical thrust component is the effective component of the force that drives the pitch sliding table 120 to generate tangential torque, thereby achieving precise adjustment of the pitch angle.

[0041] Preferably, through the cooperation of the sliding structure 221 and the sliding groove 231, the pitch angle adjustment range of the pitch sliding table 120 is -9.1° to 11.6°.

[0042] Please refer to it again. Figure 3 and Figure 4 In some embodiments, the upper surface of the pitch sliding stage 120 is provided with a slide rail 123, and the lower surface of the horizontal rotary stage 130 is provided with a second slide groove 131 that matches the slide rail 123.

[0043] Specifically, the slide rail 123 and the second slide groove 131 together form a horizontal rotary guide pair. The slide rail 123 is preferably a boss or guide rail extending in the circumferential direction, and the second slide groove 131 is a groove that fits precisely with it. The two bear the weight and overturning moment of the horizontal rotary table 130 and its load through surface contact. When the horizontal rotary table 130 rotates around its axis, the large-area contact between the slide rail 123 and the second slide groove 131 can effectively disperse contact stress and avoid loss of accuracy caused by local wear. At the same time, with the use of lubricating grease, it can ensure that stable rotational damping and positioning accuracy are maintained throughout the entire life cycle.

[0044] It should be understood that although the figure shows the form of the annular slide rail 123, in other embodiments, a segmented slide rail 123, a dovetail groove or a T-slot can also be used, as long as it can provide rotational constraint and axial support functions around the axis.

[0045] Please refer to it again. Figure 6 In some embodiments, the fixed base 310 is provided with two limiting structures 312, the top block 320 is located between the two limiting structures 312, and the horizontal adjusting rod 330 passes through the limiting structure 312 and abuts against the top block 320.

[0046] Specifically, two limiting structures 312 are symmetrically distributed on both sides of the receiving area 311 of the fixed base 310, serving as both lateral limiting components for the top block 320 and threaded support seats for the horizontal adjusting rod 330. The horizontal adjusting rod 330 adopts a fine-pitch thread design; after being screwed into the limiting structure 312, its end directly presses against the side of the top block 320. When adjusting the horizontal angle, by screwing in one side of the horizontal adjusting rod 330 and simultaneously unscrewing the other side, the axial displacement of the screw pushes the top block 320 and the horizontal rotary table 130 connected to it to rotate slightly around the axis, achieving stepless fine adjustment. After adjustment, by locking the horizontal adjusting rods 330 on both sides in opposite directions, equal and opposite preload forces are formed on both sides of the top block 320, rigidly fixing the top block 320 in the current position.

[0047] Preferably, the horizontal angle can be adjusted from -9.3° to 9.3° by means of the combination of the limiting structure 312 and the horizontal adjustment rod 330.

[0048] Please refer to it again. Figure 4In some embodiments, the horizontal rotary table 130 is provided with a second limiting hole 132, and the manual adjustment rod 340 passes through the top block 320 and is inserted into the second limiting hole 132.

[0049] Specifically, after the horizontal adjusting rod 330 has completed fine-tuning and is aligned, the manual adjusting rod 340 can be inserted into the currently aligned second limiting hole 132, acting as a set screw to form a physical stop. When the manual adjusting rod 340 touches the boundary of the interval, it acts as a mechanical hard limit, effectively preventing overtravel damage caused by misoperation.

[0050] Please refer to it again. Figure 1 and Figure 2 In some embodiments, the horizontal rotary table 130 and the pitch sliding table 120 are connected by a fixing pin 150; and / or, the surface of the manual adjustment rod 340 is covered with anti-slip texture; and / or, the contact surfaces of the pitch sliding table 120 and the support platform 110, as well as the contact surfaces of the horizontal rotary table 130 and the pitch sliding table 120, are provided with a lubricating layer.

[0051] Specifically, the fixing pin 150 passes axially through the threaded hole 141 of the horizontal rotary table 130 and is inserted into the corresponding threaded hole of the pitch slide table 120 to form a connection. As an independent safety redundancy structure, the fixing pin 150 can reliably limit the axial separation of the horizontal rotary table 130 and the pitch slide table 120 even when the manual adjustment rod 340 is pulled out, not installed, or fails due to extreme impact load, thus preventing accidental drop damage to the precision optical equipment.

[0052] Anti-slip textures can be knurled patterns, straight lines, or rough surfaces formed by etching, or covered with rubber sleeves. In outdoor rain, snow, or wet environments, or when operators wear cold-weather gloves, anti-slip textures increase the coefficient of friction of the contact surface, ensuring that the operator can hold the grip firmly and apply rotational torque accurately.

[0053] The lubrication layer can be a coated grease, a solid lubricating film, or an embedded self-lubricating material sheet, which reduces the starting friction torque and the running wear rate, and ensures the smoothness and accuracy of angle adjustment over long-term use.

[0054] In summary, the two-dimensional adjustment device in this embodiment of the invention, by setting up a support module 100, a pitch adjustment module 200, and a horizontal adjustment module 300, achieves modularity, detachability, high reusability, and low cost. The pitch adjustment module 200 and the horizontal adjustment module 300 are both independent detachable structures, which can be disassembled individually or reinstalled in other devices. When a module is damaged, only the corresponding normal module needs to be replaced, without scrapping the entire two-dimensional adjustment device, significantly reducing usage and maintenance costs. If it needs to be moved to another location, simple surface cleaning is sufficient.

[0055] The two-dimensional adjustment device has no complex transmission structure, ensuring high reliability and simple maintenance. It completely eliminates complex and precision components such as worm gears and bearings, adopting a purely mechanical screw, guide rail, and friction locking structure. When used in outdoor environments, it is not prone to jamming or wear, reducing the failure rate by more than 98%. Maintenance only requires routine cleaning and no additional professional skills are needed.

[0056] The screw drive and friction locking structure have high transmission efficiency and low resistance during manual adjustment. The pitch and horizontal angles can be adjusted by one person with one hand without the need for additional tools. The adjustment is easy and labor-saving, and the operation is convenient, which greatly improves the efficiency of outdoor operations.

[0057] Using the above structure, the two-dimensional adjustment device is made of lightweight materials such as aluminum alloy and stainless steel. It has no redundant complex structure, small size, light weight, and strong portability. The weight of the whole machine is less than or equal to 1.1KG, which is only 60% of the weight of the traditional load adjustment table.

[0058] With its high-strength structural design, the two-dimensional adjustment device has a high load capacity, with a rated load of ≥10KG. It can be adapted to large-volume outdoor optical equipment, detection sensors, laser terminals, and pole-mounted instruments, solving the problem of insufficient load capacity of traditional portable adjustment tables.

[0059] The two-dimensional adjustment device in this embodiment of the invention has an IP67 rating. All connecting screws are made of 316 stainless steel anti-loosening screws, which have good moisture resistance and can adapt to outdoor rainy, humid and dusty environments. Moreover, the two-dimensional adjustment device is a purely mechanical mechanism without electronic components. It is not limited by the lack of power supply outdoors, nor is it affected by temperature differences and vibrations. It is not afraid of internal corrosion and can work stably for a long time.

[0060] The two-dimensional adjustment device in this embodiment of the invention achieves precise adaptation of the angle adjustment range through the pitch adjustment module 200 and the horizontal adjustment module 300. The pitch angle adjustment range is -9.1° to 11.6°, and the horizontal angle adjustment range is -9.3° to 9.3°, which matches the installation and adjustment requirements of most outdoor equipment and has high adjustment accuracy.

[0061] The two-dimensional adjustment device in this embodiment of the invention has a simple overall structure, short processing time, and can be mass-produced quickly.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
