Description

A milling device for machining aluminum strips for the fixed shell of a four-axis UAV Technical Field

[0001] This utility model relates to the field of milling device technology, and in particular to a milling device for processing aluminum strips for the fixed shell of a four-axis UAV. Background Technology

[0002] In drone manufacturing, the quality of the quadcopter's fixed shell has a significant impact on the drone's performance. Aluminum strip milling is crucial for improving this quality and is therefore essential. Drones must withstand complex mechanical and environmental forces during flight; precise milling ensures the aluminum strips have appropriate dimensional accuracy, flatness, and strength, allowing for a tight fit, enhanced vibration and impact resistance, and stable component operation. Milled quadcopter fixed shells have wide applications, covering consumer, professional, and military drones, providing support and protection for internal components and ensuring stable operation in various environments, enabling different functionalities. Current devices typically require the following technologies in practical applications:

[0003] 1. Precise aluminum strip positioning technology: It can accurately fix the position of the aluminum strip, ensure the accuracy of milling, and prevent the aluminum strip from shifting during processing, which would affect the processing quality.

[0004] 2. High-efficiency milling technology: It has stable and efficient milling capabilities, enabling fast and precise milling of aluminum strips to meet production efficiency requirements.

[0005] 3. Reliable equipment control technology: It facilitates operators to control the equipment and provides timely feedback on the equipment's operating status, enabling rapid troubleshooting of equipment malfunctions.

[0006] Currently, various methods and equipment are used in the industry to mill the aluminum strips for the fixed outer shell of a quadcopter. Some processing equipment uses fixed clamping devices, where the placement and clamping points of the aluminum strip remain relatively fixed.

[0007] However, the above method has a prominent problem: when faced with aluminum strips of different lengths and milling positions, existing processing equipment cannot flexibly, efficiently and accurately adjust the clamping and fitting position. If the clamping point coincides with the milling position, the traditional fixed clamping method requires manual disassembly and adjustment of multiple clamping points, which is relatively cumbersome and inconvenient. It cannot meet the diverse processing needs and affects the work efficiency when processing different batches of aluminum strips. Summary of the Invention

[0008] To address the shortcomings of existing technologies, this utility model provides a milling device for processing aluminum strips for the fixed shell of a four-axis UAV. It solves the problem that existing processing equipment struggles to flexibly, efficiently, and accurately adjust the clamping and fitting position when dealing with aluminum strips of different lengths and milling positions. Traditional fixed clamping methods require manual disassembly and adjustment of multiple clamping points if the clamping point coincides with the milling position, making the operation relatively cumbersome and inconvenient. This fails to meet diverse processing needs and affects the work efficiency when processing different batches of aluminum strips.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A milling device for processing aluminum strips for the fixed shell of a four-axis UAV includes a milling table. A support mechanism for placing the aluminum strip is provided at the upper end of the milling table. The support mechanism includes four Z-shaped placement plates, all slidably connected to the upper end of the milling table. An equidistant adjustment pushing mechanism is provided on the outer surface of the milling table and the Z-shaped placement plates. The pushing mechanism includes a set of cross-link assemblies and an equidistant adjustment cylinder. The cross-link assemblies are rotatably connected to each other and rotatably connected to the lower ends of the four Z-shaped placement plates. The equidistant adjustment cylinder is fixedly connected to the outer surface of the milling table. The four Z-shaped placement plates are located on the outer surface of the equidistant adjustment cylinder. A positioning mechanism for clamping the aluminum strip is provided at the upper end of each of the four Z-shaped placement plates. The positioning mechanism includes four clamping cylinders and four clamping positioning plates. The four clamping cylinders are fixedly connected to the upper ends of the four Z-shaped placement plates, and the four clamping positioning plates are located on the outer surface of the four clamping cylinders.

[0011] Preferably, each of the four Z-shaped placement plates has a flat placement groove inside, and an aluminum strip body is provided inside the four flat placement grooves.

[0012] Preferably, a slide rail is fixedly connected to the upper end of the milling machine table.

[0013] Preferably, each of the four Z-shaped placement plates has a sliding groove inside.

[0014] Preferably, the outer surface of the milling table is fixedly connected to two round rod shafts, and the outer surfaces of the two round rod shafts are rotatably connected to a milling machine tool.

[0015] Preferably, a tilting motor is fixedly connected to the inner surface of the milling machine tool.

[0016] Preferably, a control panel is fixedly connected to the outer surface of the milling machine tool, and a milling processing component is slidably connected to the outer surface of the milling machine tool.

[0017] Preferably, a milling cutter is rotatably connected inside the milling assembly, and an air pump is provided on the outer surface of the milling machine tool.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Drive the equidistant adjustment cylinder mounted on the surface of the milling table. The output shaft of the equidistant adjustment cylinder extends or retracts, causing a Z-shaped placement plate connected to it to slide. When the Z-shaped placement plate slides, it squeezes and pushes a set of cross linkage assemblies to retract. Since the cross linkage assemblies are rotatably connected to the lower ends of the four Z-shaped placement plates respectively, when one Z-shaped placement plate slides, the pull of a set of cross linkage assemblies can realize the synchronous equidistant displacement of the four Z-shaped placement plates, thereby flexibly adjusting the clamping and fitting position to adapt to aluminum strips of different lengths and milling positions.

[0020] 2. After the single-sided milling of the aluminum strip body is completed, the flip motor installed in the milling machine is started through the control panel. The output shaft of the flip motor drives the round rod shaft to rotate. Since the milling table is connected to the round rod shaft, the entire milling table rotates, realizing the flip placement of the aluminum strip body. In this way, the double-sided milling of the aluminum strip can be completed directly in a single clamping operation, improving the milling efficiency. Attached Figure Description

[0027] This application provides a milling device for processing aluminum strips for the fixed shell of a four-axis UAV. It effectively solves the problem that existing processing equipment struggles to flexibly, efficiently, and accurately adjust the clamping and fitting position when dealing with aluminum strips of varying lengths and milling positions. Traditional fixed clamping methods require manual disassembly and adjustment of multiple clamping points if the clamping point coincides with the milling position, making the operation cumbersome and inconvenient, failing to meet diverse processing needs, and affecting the efficiency of processing different batches of aluminum strips. The device drives an equidistant adjusting cylinder mounted on the milling table surface. The output shaft of the equidistant adjusting cylinder extends or retracts, causing a connected Z-shaped placement plate to slide. When the Z-shaped placement plate slides, it compresses and pushes a set of cross-link assemblies to retract. Since the cross-link assemblies are rotatably connected to the lower ends of the four Z-shaped placement plates, when one Z-shaped placement plate slides, the pull of the cross-link assemblies allows for synchronous equidistant displacement of all four Z-shaped placement plates, thereby flexibly adjusting the clamping and fitting position to adapt to aluminum strips of different lengths and milling positions.

[0028] Example

[0029] As shown in Figures 1, 2, 3, and 4, the technical solution in this application effectively solves the problem that existing processing equipment struggles to flexibly, efficiently, and accurately adjust the clamping and fitting position when dealing with aluminum strips of different lengths and milling positions. Traditional fixed clamping methods require manual disassembly and adjustment of multiple clamping points if the clamping point coincides with the milling position, making the operation relatively cumbersome and inconvenient. This fails to meet diverse processing needs and affects the efficiency of processing different batches of aluminum strips. The overall concept is as follows: A milling device for processing aluminum strips for a quadcopter fixed shell of a drone includes a milling table 11. The upper end of the milling table 11 is provided with a support mechanism for placing aluminum strips. The support mechanism includes four Z-shaped placement plates. 12. Four Z-shaped placement plates 12 are slidably connected to the upper end of the milling table 11. The outer surfaces of the milling table 11 and the Z-shaped placement plates 12 are provided with equidistant adjustment pushing mechanisms. The pushing mechanisms include a set of cross-link assemblies 13 and equidistant adjustment cylinders 14. The cross-link assemblies 13 are rotatably connected to each other and rotatably connected to the lower ends of the four Z-shaped placement plates 12. The equidistant adjustment cylinders 14 are fixedly connected to the outer surface of the milling table 11. The four Z-shaped placement plates 12 are positioned on the outer surface of the equidistant adjustment cylinders 14. The upper ends of the four Z-shaped placement plates 12 are each provided with a positioning mechanism for clamping aluminum strips. The positioning mechanism includes four clamping cylinders 15 and four clamping positioning plates 16. The four clamping cylinders 15... Four Z-shaped placement plates 12 are fixedly connected to the upper ends of the four clamping positioning plates 16, which are respectively set on the outer surfaces of the four clamping cylinders 15. Each of the four Z-shaped placement plates 12 has a flat placement groove 17 inside, and an aluminum strip body 18 is placed inside the four flat placement grooves 17. The four clamping positioning plates 16 are respectively set on the outer surfaces of the aluminum strip body 18. A slide rail 19 is fixedly connected to the upper end of the milling table 11. The aluminum strip body 18 to be milled is placed inside the four Z-shaped placement plates 12. The Z-shaped placement plates 12 serve as support platforms, and the four Z-shaped placement plates 12 also correspond to clamping positioning points. The four flat placement grooves 17 inside the four Z-shaped placement plates 12 provide space for the placement of the aluminum strip body 18. After placement... After completion, four clamping cylinders 15 are activated simultaneously. The output shafts of the four clamping cylinders 15 drive the clamping positioning plate 16 to slide outward and adhere to the surface of the aluminum strip body 18, thereby completing the clamping and fixing of the aluminum strip body 18 and ensuring the stability of the aluminum strip body 18 during milling. The aluminum strip body 18 is then milled and cut. The cut product serves as the shell of the quadcopter, providing shielding and protection. Before milling, the equidistant adjusting cylinder 14 mounted on the surface of the milling table 11 is driven. The output shaft of the equidistant adjusting cylinder 14 extends or retracts, thereby driving a Z-shaped placement plate 12 to slide. When the Z-shaped placement plate 12 slides, it compresses and pushes a set of cross linkage assemblies 13 to retract. The cross linkage assembly 13 consists of two sets of linkages.Two sets of connecting rods are placed in a crisscross pattern and are rotatably connected to each other. When a Z-shaped placement plate 12 slides, it will achieve synchronous and equidistant displacement through the pulling of a set of cross-link assemblies 13. The four synchronously sliding and equidistantly adjustable Z-shaped placement plates 12 can flexibly adjust the clamping and fitting position to meet the needs of different lengths and milling positions.

[0030] Each of the four Z-shaped placement plates 12 has a sliding groove 21 inside. The four sliding grooves 21 are all set on the outer surface of the slide rail 19. Two round rod shafts 22 are fixedly connected to the outer surface of the milling table 11. The outer surface of the two round rod shafts 22 is rotatably connected to the milling machine tool 23. The inner surface of the milling machine tool 23 is fixedly connected to the tilting motor 24. The two round rod shafts 22 are set on the outer surface of the tilting motor 24. During the sliding adjustment of the four Z-shaped placement plates 12, they will slide on the surface of the slide rail 19 through the sliding grooves 21 inside, providing a more reliable motion trajectory. After the single-sided milling of the aluminum strip body 18 is completed, the tilting motor 24 installed in the milling machine tool 23 can be started. The output shaft of the tilting motor 24 drives the round rod shafts 22 to rotate, thereby rotating the entire milling table 11. The rotation of the milling table 11 realizes the tilting and placement of the aluminum strip body 18. In a single clamping operation, double-sided milling can be completed directly, and the milling efficiency is more efficient.

[0031] A control panel 25 is fixedly connected to the outer surface of the milling machine tool 23. A milling machining assembly 26 is slidably connected to the outer surface of the milling machine tool 23. A milling cutter 27 is rotatably connected inside the milling machining assembly 26. An air pump 28 is installed on the outer surface of the milling machine tool 23. The air pump 28 is connected to four clamping cylinders 15 and equidistant adjusting cylinders 14 through rubber hoses. The air pump 28 provides compressed air as a power source to control the ejection or retraction of its output shaft. The control panel 25 contains buttons for controlling start and stop and a display screen. The display screen can directly display alarm information, enabling operators to more efficiently find the cause of equipment errors. The milling machine tool 23 drives the milling cutter 27 to achieve dual-axis displacement through the milling machining assembly 26 on its surface. The milling machining assembly 26 drives the milling cutter 27 to rotate and approach the aluminum strip body 18 for milling.

[0032] To address the problems existing in the prior art, this utility model provides a milling device for processing aluminum strips for the fixed shell of a four-axis UAV. It drives an equidistant adjusting cylinder 14 mounted on the surface of the milling table 11. The output shaft of the equidistant adjusting cylinder 14 extends or retracts, causing a Z-shaped placement plate 12 connected to it to slide. When the Z-shaped placement plate 12 slides, it squeezes and pushes a set of cross linkage assemblies 13 to retract. Since the cross linkage assemblies 13 are rotatably connected to the lower ends of the four Z-shaped placement plates 12 respectively, when one Z-shaped placement plate 12 slides, the pull of a set of cross linkage assemblies 13 can realize the synchronous equidistant displacement of the four Z-shaped placement plates 12, thereby flexibly adjusting the clamping and fitting position to adapt to aluminum strips of different lengths and milling positions.

[0045] The flip motor 24: The output shaft drives the round rod shaft 22 to rotate, so that the milling table 11 rotates as a whole, realizing the flipping of the aluminum strip body 18, thereby completing double-sided milling in a single clamping operation and improving processing efficiency;

[0050] Working principle:

[0051] The first step involves placing the aluminum strip body 18 to be milled into the planar placement slots 17 inside the four Z-shaped placement plates 12. The Z-shaped placement plates 12 serve as a support platform for the aluminum strip, and their four positions correspond to clamping and positioning points, providing a stable initial placement position for the aluminum strip. The milling machine tool 23, through its surface-mounted milling assembly 26, drives the milling cutter 27 to achieve dual-axis displacement. The milling assembly 26 drives the milling cutter 27 to rotate and approach the aluminum strip body 18 for milling. The resulting product is used to manufacture the shell of a quadcopter for a drone. The air pump 28 not only provides power to the clamping cylinder 15 but also provides compressed air to the equidistant adjustment cylinder 14 through a rubber hose, controlling the extension or retraction of its output shaft to achieve equidistant adjustment of the Z-shaped placement plates 12. Once the aluminum strip body 18 has been milled on one side... After completion, the tilting motor 24 installed in the milling machine tool 23 is started via the control panel 25. The output shaft of the tilting motor 24 drives the round rod shaft 22 to rotate. Since the milling table 11 is connected to the round rod shaft 22, the entire milling table 11 rotates, realizing the tilting and placement of the aluminum strip body 18. In this way, the double-sided milling of the aluminum strip can be completed directly in a single clamping operation, improving the milling efficiency. The operator controls the air pump 28, clamping cylinder 15, equidistant adjustment cylinder 14, tilting motor 24, and milling assembly 26 through the start and stop buttons inside the control panel 25. The display screen of the control panel 25 can directly display alarm information, helping the staff to quickly and efficiently find the equipment error problem so as to carry out timely maintenance and adjustment and ensure the normal operation of the milling device.

[0052] In the second step, the air pump 28 provides compressed air to the four clamping cylinders 15 via rubber hoses as a power source. After the aluminum strip is placed, the output shafts of the four clamping cylinders 15 drive the clamping positioning plate 16 to slide outward and push it against the surface of the aluminum strip body 18, thereby completing the clamping and fixing of the aluminum strip body 18 and ensuring the stability of the aluminum strip during milling. Before milling, according to the length of the aluminum strip and the milling position requirements, the equidistant adjustment cylinder 14 installed on the surface of the milling table 11 is driven. The output shaft of the equidistant adjustment cylinder 14 extends or retracts, driving the clamping positioning plate 16 to slide outward and push it against the surface of the aluminum strip body 18, thus completing the clamping and fixing of the aluminum strip body 18 and ensuring the stability of the aluminum strip during milling. A Z-shaped placement plate 12 connected to it slides. When the Z-shaped placement plate 12 slides, it squeezes and pushes a set of cross linkage assemblies 13 to retract (the cross linkage assembly 13 consists of two sets of mutually intersecting and rotatably connected linkages). Since the cross linkage assembly 13 is rotatably connected to the lower ends of the four Z-shaped placement plates 12 respectively, when one Z-shaped placement plate 12 slides, the four Z-shaped placement plates 12 can be synchronously and equidistantly displaced by the pulling of a set of cross linkage assemblies 13, thereby flexibly adjusting the clamping and fitting position to adapt to aluminum strips of different lengths and milling positions.

[0053] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
