[0002] The unmanned aerial vehicle landing gear is a key load-bearing component for supporting the weight of the whole machine and absorbing landing impact, and the surface treatment quality thereof directly affects flight safety and service life. The traditional polishing process faces three technical bottlenecks. First, the landing gear is usually in a special-shaped tubular structure and has multiple discontinuous curved surfaces, and conventional polishing equipment cannot realize synchronous processing of multiple surfaces. Second, although the existing mechanical arm polishing scheme can complete complex curved surface processing, it has problems of high equipment investment cost and long programming and debugging cycle, and manual polishing not only has low efficiency but also cannot guarantee the uniformity of the curved surface transition area. In particular, for the modern unmanned aerial vehicle landing gear made of high-strength aluminum alloy material, the surface thereof needs to meet both roughness requirements and stress relief requirements, and the traditional single-station polishing equipment cannot balance efficiency and quality. Moreover, the most prominent contradiction is that the special geometry of the connection part between the landing gear and the fuselage makes it difficult for conventional abrasive wheel devices to process the inner and outer surfaces at the same time, and the landing gear often needs to be clamped twice, which not only reduces the processing precision but also easily causes joint defects. In addition, the existing equipment lacks effective control over the cooling liquid in the polishing process, which easily causes thermal deformation of the workpiece surface. The existing technology needs to be improved in view of the above problems. SUMMARY

DETAILED DESCRIPTION

[0019] The following will be described in detail in combination with the accompanying Figures 1-5 The application will be further described in detail.

[0020] The embodiment of the application discloses a double-station vertical sand wheel unmanned aerial vehicle landing gear polishing machine.

[0021] It should be noted that in the description of the application, it should be understood that the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the application and simplifying the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the application.

[0022] Referring to Figures 1-5 A double-station vertical sand wheel unmanned aerial vehicle landing gear polishing machine, comprising: The double-station vertical grinding wheel unmanned aerial vehicle landing gear polishing machine is provided with a mounting table 1, a landing gear mounting mechanism 2, a polishing mechanism 3 and a rotating plate 4. The bottom of the mounting table 1 is provided with a first sliding table 11, the top end of which is fixed with a T-shaped plate, and the two sides of the T-shaped plate are provided with a second sliding table 12. The landing gear mounting mechanism 2 is movably connected to the first sliding table 11 to adjust the position and angle. The polishing mechanism 3 is fixed with the second sliding table 12 and comprises a derived sliding table 34, a vertical grinding wheel 33 and a polishing rod 39 which moves synchronously with the grinding wheel 33. The two are oppositely arranged at the bottom of the derived sliding table 34, and the landing gear is arranged between the two. The rotating plate 4 is movably connected with the outer wall of the derived sliding table 34, and an adjusting wheel 41 is arranged on the rotating plate 4 to control the position of the polishing rod 39.

[0023] The first sliding table 11 of the mounting table 1 provides a horizontal movement basis, and the second sliding table 12 can realize horizontal displacement of the polishing mechanism 3. The precise positioning can be realized by using a ball screw or a linear guide rail. The landing gear mounting mechanism 2 adjusts the spatial coordinates of the workpiece through the sliding of the first sliding table 11, and the angle adjusting function is combined to adapt to different curved surface profiles. The vertical grinding wheel 33 of the polishing mechanism 3 and the polishing rod 39 form a complementary polishing unit. The grinding wheel 33 is responsible for the main surface treatment, and the polishing rod 39 covers the side edge or recessed area by moving through the derived sliding table 34. The combination of the rotating plate 4 and the adjusting wheel 41 can change the horizontal position of the polishing rod 39.

[0024] Specifically, after the workpiece is clamped on the landing gear mounting mechanism 2, the first sliding table 11 drives it to move to the polishing station along the horizontal direction. The second sliding table 12 controls the height of the grinding wheel 33 to make it contact the main surface of the workpiece, and at the same time, the derived sliding table 34 drives the polishing rod 39 to move along a specific track to process the inside edge area. Before polishing, the rotating plate 4 is rotated according to the shape of the workpiece, and the adjusting wheel 41 changes the position of the polishing rod 39, so that it forms different surface polishing work with the grinding wheel 33. The synchronous rotation of the grinding wheel 33 and the polishing rod 39 produces a composite polishing effect.

[0025] Compared with the prior art, the conventional equipment needs to adjust the posture of the workpiece multiple times to complete multi-surface polishing, while the present scheme realizes one-time clamping and multi-surface synchronous machining through double-station cooperative work. The existing single-grinding-head equipment cannot cover complex curved surfaces. The present design adopts a combined structure of the grinding wheel 33 and the polishing rod 39, combined with the angle-adjustable rotating plate 4, which significantly expands the machining range. The conventional equipment relies on a mechanical arm for three-dimensional movement, and the present scheme simplifies the motion control logic through the mechanical linkage of the sliding table and the rotating plate 4.

[0026] Through the above technical scheme, the present application realizes multi-surface synchronous polishing of the landing gear, reduces the number of repeated positioning of the workpiece, improves the machining efficiency, and the synchronous movement of the grinding wheel 33 and the polishing rod 39 can cover the main surface and the edge area, so that multiple surfaces can be polished synchronously. The double-station design makes the equipment suitable for batch production scenes, effectively solving the technical problems of low efficiency and high cost of traditional processes.

[0027] Referring toFigures 1-5 The application further provides a landing gear mounting mechanism 2 in a double-station vertical grinding wheel unmanned aerial vehicle landing gear polishing machine, which comprises a rotating disc 21, the rotating disc 21 being in sliding connection with a first sliding table 11, a connecting rod 22 being coaxially and fixedly connected to the top end of the rotating disc 21, a U-shaped block 23 being fixedly connected to the top end of the connecting rod 22, a hinged block 24 being rotatably connected to one side of the connecting rod 22, a supporting table 25 being fixedly connected to the outer wall of the hinged block 24, a plurality of hydraulic rods 26 and a rotating rod 28 being rotatably connected to the outer wall of the hinged block 24, the output end of the hydraulic rod 26 being movably connected with the outer wall of the rotating rod 28, and a chuck 27 being fixedly connected to the top end of the rotating rod 28, the chuck 27 being used for mounting the landing gear.

[0028] The rotating disc 21 is a circular platform used for carrying the landing gear and rotating to adjust the position of the workpiece, the first sliding table 11 is used to drive the rotating disc 21 to move, so as to change the polishing position of the landing gear in the horizontal direction, the connecting rod 22 is a vertical supporting structure connecting the rotating disc 21 and the U-shaped block 23, and can be specifically implemented by a cylindrical metal rod, which is used for transmitting the movement of the rotating disc 21 and keeping the stability of the U-shaped block 23, the U-shaped block 23 is a fixed block with a U-shaped opening at the top, which is used for providing the mounting basis of the hinged block 24, the hinged block 24 is a component rotatably connected with the connecting rod 22, and can be specifically implemented by a metal block with a bearing, which is used for driving the supporting table 25 and the hydraulic rod 26 to adjust the angle through rotation, the supporting table 25 is a base used for fixing the hydraulic rod 26 and the rotating rod 28, and can be specifically implemented by a rectangular metal plate, which is used for providing support for the hydraulic rod 26 and the rotating rod 28, the hydraulic rod 26 is a linear execution element achieving extension and retraction through hydraulic driving, and can be specifically implemented by a double-acting hydraulic cylinder, which is used for driving the rotating rod 28 to rotate around the hinge point through extension and retraction, and the rotating rod 28 is a rotating rod connected with the hydraulic rod 26, and can be specifically implemented by a metal rod with an axle hole, which is used for changing the inclination angle of the chuck 27 through the driving of the hydraulic rod 26.

[0029] Specifically, when the landing gear is fixed by the chuck 27, the horizontal sliding of the turntable 21 along the first sliding table 11 can drive the landing gear to move transversely as a whole, so as to adjust the relative position of the workpiece and the grinding wheel 33 or the polishing rod 39. The fixed connection of the connecting rod 22 and the U-shaped block 23 ensures the rigidity of the support structure, avoiding the position deviation caused by vibration during polishing. The articulated block 24 is articulated on one side of the connecting rod 22 by rotating, so that the support table 25 and the hydraulic rod 26 can be adjusted in pitch angle around the articulation point. The extension and retraction movement of the hydraulic rod 26 drives the swing of the rotating rod 28 around the rotating fulcrum on the articulated block 24, so as to change the inclination angle of the chuck 27 and the landing gear, and realize the polishing adaptation of the landing gear with different curved surfaces. The coordinated action of multiple hydraulic rods 26 can further refine the angle adjustment range, for example, by retracting the unilateral hydraulic rod 26 to make the chuck 27 tilt to one side, or synchronously extending and retracting the bilateral hydraulic rods 26 to realize the angle fine adjustment in the vertical direction, wherein the polishing rod 39 of the grinding wheel 33 can also provide relative pressure for double-sided polishing, so that the workpiece polishing is more stable, wherein the driving motor is arranged in the turntable 21, which is convenient for controlling the rotation of the connecting rod 22, so as to control the rotation polishing adjustment position of the workpiece.

[0030] Compared with the prior art, the traditional polishing equipment usually relies on the multi-axis movement of the mechanical arm to realize the posture adjustment of the landing gear, while the present scheme combines the horizontal movement of the turntable 21 with the angle adjustment driven by the hydraulic rod 26, so that the multi-degree-of-freedom position control can be realized by only simple mechanical structure. In the prior art, the landing gear fixing device is usually a rigid clamp, which is difficult to adapt to the polishing requirements of complex curved surfaces, while the present scheme uses the linkage design of the articulated block 24 and the hydraulic rod 26, so that the chuck 27 can superimpose the pitch angle change on the basis of horizontal movement, thereby expanding the polishing coverage and reducing the manual intervention.

[0031] Through the above technical scheme, the present application can quickly adjust the horizontal position and inclination angle of the landing gear through the cooperation of the turntable 21 and the hydraulic rod 26, so as to accurately position the grinding wheel 33 or the polishing rod 39 in different curved surface areas, reduce the number of repeated clamping, and simplify the angle adjustment mechanism by the combination design of the articulated block 24 and the hydraulic rod 26, thereby reducing the equipment manufacturing cost and improving the adaptability to irregular shaped landing gears.

[0032] Referring to Figures 1-5 , the present application further proposes that the outer wall of the articulated block 24 is fixedly connected with a motor 241, and the outer wall of the articulated block 24 is fixedly connected with a driving rod, which is fixedly connected with the output shaft of the motor 241 through the U-shaped block 23.

[0033] Specifically, the motor 241 is fixed to the outer wall of the hinged block 24, and a rigid transmission structure is formed by the driving rod and the through connection of the U-shaped block 23. When the motor 241 is started, the output shaft drives the driving rod to rotate around the axis, and the driving rod transmits the rotary motion to the hinged block 24 through the through hole of the U-shaped block 23, so that the hinged block 24 is angularly deflected relative to the U-shaped block 23. This structure directly drives the hinged block 24 to rotate through the motor 241, avoiding the gap error existing in the traditional hydraulic or gear transmission, and ensuring that the support table 25 and the clamped landing gear can accurately adjust the polishing angle.

[0034] With reference Figures 1-5 The polishing mechanism 3 further comprises a motor 31 and an outer cover 32. The motor 31 is installed on the second sliding table 12, and the outer cover 32 is fixedly connected with the second sliding table 12. The output end of the motor 31 is drivingly connected with a sanding wheel 33. The sanding wheel 33 is coaxially and rotatably connected in the outer cover 32. A derivative rod is fixedly connected with the center of the sanding wheel 33. A sliding sleeve 35 is slidingly connected on the derivative sliding table 34. A shaft rod 36 is penetratingly connected on the sliding sleeve 35. A belt pulley set 37 is arranged between the shaft rod 36 and the derivative rod. A bottom rod 38 is rotatably connected at the bottom of the sliding sleeve 35. A polishing rod 39 is detachably connected with the bottom rod 38.

[0035] The motor 31 is a power source for driving the sanding wheel 33 to rotate. Specifically, a servo motor 31 or a stepping motor 31 can be used to achieve this. The rotation speed is accurately controlled to adapt to different polishing requirements. The outer cover 32 is a protective structure that wraps the sanding wheel 33. Specifically, a metal shell can be used to achieve this. It is used to isolate the debris and cooling liquid splashing generated during the polishing process. The derivative rod is a transmission component that extends coaxially with the sanding wheel 33. Specifically, a stepped shaft structure can be used to achieve this. It is used to transmit power to the belt pulley set 37. The sliding sleeve 35 is a sliding component that moves along the derivative sliding table 34. Specifically, a linear bearing and guide rail structure can be used to achieve this. It is used to adjust the horizontal position of the polishing rod 39. The belt pulley set 37 is a transmission device that connects the derivative rod and the shaft rod 36. Specifically, a combination of synchronous belts and pulleys can be used to achieve this. It ensures the synchronicity of power transmission.

[0036] Specifically, the motor 31 drives the sanding wheel 33 to rotate at high speed in the outer cover 32 through the output shaft, and at the same time transmits the rotary power to the belt pulley set 37 through the coaxially fixed derivative rod. The belt pulley set 37 drives the shaft rod 36 to rotate in the sliding sleeve 35. The horizontal sliding of the sliding sleeve 35 along the derivative sliding table 34 adjusts the transverse position of the polishing rod 39. The rotary power of the shaft rod 36 is transmitted to the detachable polishing rod 39 through the bottom rod 38, so that it moves synchronously with the sanding wheel 33. When the landing gear is clamped on the chuck 27, the sanding wheel 33 is responsible for the main polishing surface treatment, and the polishing rod 39 can polish the side surface or recessed area of the landing gear synchronously through the rotation of the bottom rod 38 and the position adjustment of the sliding sleeve 35.

[0037] Compared with the prior art, the traditional polishing equipment relies on a single abrasive wheel 33 for single-sided processing, while the present scheme realizes the synchronous driving of the abrasive wheel 33 and the polishing rod 39 through the power transmission structure of the derived rod and the pulley set 37. The auxiliary polishing tool in the prior art usually needs an independent driving source, and the present scheme drives multiple polishing components with the same motor 31, avoiding the complexity of additional power configuration.

[0038] Through the above technical scheme, the present application solves the problem of multi-surface synchronous polishing of the unmanned aerial vehicle landing gear, and through the cooperation of the single power source driving the abrasive wheel 33 and the adjustable polishing rod 39, the synchronous processing of the main polishing surface and the complex curved surface can be completed in one clamping, significantly reducing the number of repeated positioning, and the detachable polishing rod 39 design facilitates quick replacement of adaptive tools according to the shape of the workpiece.

[0039] Referring to Figures 1-5 , the present application further proposes that a bevel gear set 351 is arranged between the shaft rod 36 and the bottom rod 38, and the bevel gear set 351 is located inside the embedded sleeve 35.

[0040] Specifically, when the motor 31 drives the abrasive wheel 33 to rotate, the derived rod transmits power to the shaft rod 36 through the pulley set 37, and the shaft rod 36 converts the horizontal rotating power into the vertical rotating power of the bottom rod 38 through the bevel gear set 351, thereby driving the polishing rod 39 to perform polishing work.

[0041] Referring to Figures 1-5 , the present application further proposes that the adjusting wheel 41 abuts against the belt in the pulley set 37.

[0042] Among them, the adjusting wheel 41 refers to a device for adjusting the position or tension of the belt, which can be realized by a roller with a groove, by contacting the belt to change its motion trajectory. Among them, the pulley set 37 refers to a transmission structure composed of a belt and at least two pulleys, which can be realized by a synchronous belt and a pulley, used for transmitting rotating power, wherein abutting refers to the state of keeping contact between the adjusting wheel 41 and the belt, which can be realized by the groove of the adjusting wheel 41 and the surface of the belt, to ensure the stability of the position of the belt during transmission.

[0043] Specifically, the adjusting wheel 41 is installed on the rotating plate 4, and by rotating the adjusting wheel 41, the contact position or pressure of the belt in the pulley set 37 can be changed. When the belt is loose or deviated due to long-term use, the adjusting wheel 41 exerts lateral pressure on the belt through the abutting action, thereby correcting the position of the belt or increasing the tension. At the same time, the rotation of the rotating plate 4 can pull the embedded sleeve 35 to slide, controlling the position of the polishing rod 39.

[0044] Referring to Figures 1-5The diameter of the polishing rod 39 is smaller than the thickness of the grinding wheel 33, and the axis of the polishing rod 39 is in the same horizontal plane as the middle line of the thickness of the grinding wheel 33.

[0045] Specifically, when the grinding wheel 33 polishes the main surface of the landing gear, the smaller diameter of the polishing rod 39 can simultaneously supplement the processing of the side wall or corner part. Since the polishing rod 39 and the rotating axis of the grinding wheel 33 are in the same horizontal plane, the polishing tracks of the two form a complementary relationship in space, avoiding the polishing blind area caused by positional deviation. Under the drive of the derived sliding table 34, the polishing rod 39 can follow the contour of the landing gear, while the grinding wheel 33 rotates at a fixed angle. The synergistic effect of the two realizes the synchronous processing of complex surfaces.

[0046] Compared with the prior art, the traditional polishing equipment usually uses a single grinding tool for sequential processing, which cannot process the main surface and the detail part of the landing gear at the same time. The present scheme realizes the multi-surface processing of two different polishing tools in the same process through the cooperative design of size matching and spatial positioning, eliminating the time loss of repeatedly changing tools or adjusting the position of the workpiece in the traditional process.

[0047] Through the above technical scheme, the present application solves the coordination problem of synchronous polishing of irregular structural parts, and realizes one-time processing of the main surface and the detail part. The spatial cooperation relationship between the polishing rod 39 and the grinding wheel 33 effectively avoids tool interference, while ensuring the consistency of the processing quality of different forms of polishing surfaces, especially suitable for unmanned aerial vehicle landing gear structures with edges and grooves.

[0048] Referring to Figures 1-5 The present application further proposes that the top of the cover 32 is provided with a cooling liquid cylinder 331, and the top and bottom of the cover 32 are respectively provided with a liquid inlet and a liquid outlet pipe.

[0049] Specifically, the cooling liquid in the cooling liquid cylinder 331 enters the inside of the cover 32 from the liquid inlet by gravity or pump pressure, forms a flow path along the rotating direction of the grinding wheel 33, and carries away metal chips from the bottom liquid outlet pipe after absorbing the heat generated by the contact between the grinding wheel 33 and the landing gear. During the circulation of the cooling liquid, the surface temperature of the grinding wheel 33 is controlled within a safe range, avoiding the accelerated wear of the grinding wheel or the deformation of the landing gear material due to overheating.

[0050] Referring to Figures 1-5 The present application further proposes that the lowest end of the polishing rod 39 is lower than the lowest end of the chuck 27.

[0051] Specifically, when the landing gear is fixed by the chuck 27, the bottom area of the landing gear can extend below the lowest end of the chuck 27. By setting the lowest end of the polishing rod 39 below the lowest end of the chuck 27, the polishing rod 39 can completely cover the bottom extension area of the landing gear during polishing. When the derived slide platform 34 drives the polishing rod 39 to move in the vertical direction, the lowest movement track of the polishing rod 39 can cover the space below the chuck 27, thereby avoiding the polishing blind area of the bottom of the landing gear caused by the obstruction of the structure of the chuck 27.

[0052] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, so: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
