Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) cabin door lifting couplings, specifically couplings and their manufacturing processes. Background Technology

[0002] As is well known, drone cabin doors are installed on the drone body and are used to close or open the drone's internal space. Drone cabin doors are usually opened and closed using a lifting device, which controls the opening and closing of the drone cabin door.

[0003] Existing drone door lifting devices typically use couplings to connect shafts. These couplings are usually L-shaped couplings, which rely on internal L-shaped elastic elements or special structures to compensate for shaft displacement and ensure smooth operation of the transmission system. L-shaped couplings typically include a claw plate, L-shaped elastic elements, and fastening bolts. The claw plate usually has notches, which are then used to lock and fix the claw plate and shaft together with the fastening bolts.

[0004] However, after the claw disc is connected to the shaft, since the inner wall of the claw disc is usually smooth, the outer wall of the shaft and the inner wall of the claw disc may slip after the shaft rotates for a long time, which affects the use of the shaft. As a result, the coupling is not easy to protect against slippage inside, which has certain limitations. Summary of the Invention

[0039] This invention also provides a coupling manufacturing process, including the following specific steps:

[0040] Step 1: Based on the environmental factors of the coupling's use, select appropriate materials, then design and draw the drawings to determine the coupling's external dimensions and bore diameter parameters. At the same time, select the materials for each mechanism and component on the coupling and customize the corresponding dimensions.

[0041] Step 2: According to the design drawings, use a shearing machine, wire saw, mechanical cutting or laser cutting to cut the raw materials of the coupling and other required components into the corresponding size and shape to form blanks. Then, heat treat the cut blanks to improve the mechanical properties and wear resistance of the materials.

[0042] Step 3: Then, the processed blanks are processed one by one by roughing, semi-finishing and laser cutting to obtain the corresponding parts and coupling parts;

[0043] Step 4: After processing, the inner wall of the connector's claw plate is re-surfaced by fine scraping, planing, milling, or grinding to give the inner wall of the claw plate a certain friction. Then, the coupling is assembled, and the corresponding parts of multiple mechanisms are assembled accordingly. During the assembly process, the connection is fixed by laser cutting. After assembly, each mechanism is formed.

[0044] Step 5: Then, adjust the coupling and test its use after it is in conjunction with the mechanism. After the adjustment is completed, package it accordingly.

[0045] This invention discloses a coupling and its manufacturing process, which have the following beneficial effects:

[0046] 1. The first and second claw discs are equipped with protective cylinders inside. The anti-slip strips and anti-slip teeth on the protective cylinders increase the friction between the inner walls of the first and second claw discs. The support cylinder supports the protective cylinders and installs the protective cylinders, which helps to increase the friction between the first and second claw discs and the shaft body, so as to prevent slippage inside the first and second claw discs and facilitate increase in the stability of the connection between the first and second claw discs and the shaft body.

[0047] 2. The cooperation of the limiting plate, arc plate, guide post, fixed seat and through plate, the limiting plate limits the top of the support cylinder, the arc plate connects adjacent limiting plates, and the through plate and fixed seat slide guide the installation of the limiting plate, which facilitates the installation and disassembly of the support cylinder, so as to replace the support cylinder with support cylinders of different inner diameters and make it easy to adapt to shafts of different sizes for connection and use;

[0048] 3. The sliding frame, support frame, locking plate, connecting cylinder, sliding rod, first spring, mounting rod, sliding ring, mounting ring, operating column, and second spring work together to allow the sliding frame to drive the locking plate to limit the position of the support frame, which in turn limits the position of the second slide plate and the anti-slip cylinder. The elastic force of the first spring pushes the sliding frame to slide horizontally, causing the locking plate to disengage from the support frame and move away from the top of the second slide plate. This facilitates the independent replacement of the anti-slip cylinder without disassembling the support cylinder, saving operation steps and making operation more convenient.

[0049] 4. The auxiliary frame, snap-fit ​​plate, and anti-detachment column work together to limit the relative position of the insertion plate and the fixed seat by the snap-fit ​​plate driven by the auxiliary frame. The auxiliary frame drives the anti-detachment column to move and the anti-detachment column abuts against the end of the fastening bolt, which facilitates the installation and removal of the limiting plate and the support cylinder. At the same time, it helps to protect the fastening bolt from loosening and prevents the fastening bolt from moving arbitrarily.

[0050] 5. The cooperation of the support rod, connecting plate, connecting column, connecting frame and baffle allows the connecting plate to engage with the connecting column after sliding away from the top of the second slide plate, thereby limiting the sliding frame. The connecting frame and baffle limit the sliding position of the sliding frame, and the baffle limits the rotation position of the connecting plate. This helps to prevent the sliding frame from slipping, facilitates the storage of the sliding frame, and allows for the operation of the anti-slip cylinder. Attached Figure Description

Detailed Implementation

[0061] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0062] This embodiment of the application solves the problem of low friction between the first claw disk 1 and the second claw disk 2 and the shaft by providing a coupling. During use, the support cylinder 31 is connected to the first claw disk 1 and the second claw disk 2, and the anti-slip cylinder 33 is installed inside the support cylinder 31. Then, the shaft is installed, ensuring that the anti-slip strip 35 and anti-slip teeth 36 are tightly fitted against the outer wall of the shaft. The fastening bolt 10 is then rotated to lock the first claw disk 1 and the second claw disk 2 onto the shaft. The limiting plate 41 is connected to the first claw disk 1 and the second claw disk 2, driving the insertion plate 45 to connect with the fixed seat 44. Finally, the auxiliary frame 71 drives the snap-fit ​​plate 72 to connect with the insertion plate. The 45 and the fixed seat 44 are interlocked, and the anti-detachment column 73 limits the end of the fastening bolt 10. Then, the positioning column 85 locks the position of the auxiliary frame 71, and it can be used. If the anti-slip cylinder 33 needs to be removed and replaced independently, the connecting frame 94 is lifted so that the connecting frame 94 is away from the side of the sliding frame 51, and the baffle 95 is away from the side of the connecting plate 92. Then, the sliding frame 51 is pushed so that the sliding frame 51 is away from the top of the second slide plate 34. Then, the connecting plate 92 is rotated so that the connecting plate 92 is engaged with the connecting column 93, which limits the sliding frame 51. Then, the anti-slip cylinder 33 can be removed.

[0063] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0064] This invention discloses a coupling.

[0065] According to the appendix Figure 1 As shown in Figure 8, the device includes a first claw disk 1, a second claw disk 2 located below the first claw disk 1, an elastic body 6 located between the first claw disk 1 and the second claw disk 2, and fastening bolts 10 threadedly connected to both the first claw disk 1 and the second claw disk 2. This facilitates the movement of the notches on the first claw disk 1 and the second claw disk 2 to bring them closer together, thereby locking the first claw disk 1 and the second claw disk 2 to the two shafts.

[0066] Furthermore, both the first claw plate 1 and the second claw plate 2 are provided with a protective mechanism 3.

The first sliding plate 32 provides vertical guidance for the installation of the support cylinder 31, increasing its installation stability. The second sliding plate 34 also provides vertical guidance for the installation of the anti-slip cylinder 33, further increasing its installation stability. The anti-slip strip 35 is made of a textured, wear-resistant material. It supports the anti-slip teeth 36, which contact the outside of the shaft, increasing the friction between the shaft and the inner wall of the first claw plate 1 or the second claw plate 2, thus protecting the shaft from damage. The inside of the claw disc 2 is protected against slippage to increase the stability of the shaft. An anti-slip cylinder 33 is slidably installed inside the support cylinder 31, which supports the anti-slip strip 35.

One end of the third spring 84 is fixedly connected to the guide ring 82, and the other end of the third spring 84 is fixedly connected to the moving ring 83.

[0072] More specifically, the connecting mechanism 9 includes a support rod 91, a connecting column 93, and a connecting frame 94. The support rod 91 facilitates the rotation and sliding of the connecting plate 92. The connecting column 93 facilitates its engagement with the connecting plate 92 after rotating it to ninety degrees, thereby limiting the movement of the sliding frame 51. The connecting frame 94 is L-shaped, which helps to hold the side of the sliding frame 51, preventing it from sliding freely due to centrifugal force. The connecting frame 94 also facilitates the up-and-down movement of the baffle 95. The support rod 91 is fixedly connected to the side of the limiting plate 41, and the outer wall of the support rod 91 is rotatably connected to the connecting plate 92, which facilitates its engagement with the connecting column 93 to...

The connecting column 93 is fixedly connected to the side of the sliding frame 51. The connecting column 93 is matched with the inner cavity of the fourth through groove. The connecting frame 94 is fixedly connected to the outer wall of the operating column 510. The bottom of the inner wall of the connecting frame 94 is fixedly connected with a baffle 95, which helps to limit the position of the connecting plate 92 and prevent the connecting plate 92 from rotating at will. The vertical movement distance of the connecting frame 94 is less than the distance at which the mounting rod 57 and the sliding rod 55 are separated.

[0074] Step 1: Based on the environmental factors of the coupling's use, select appropriate materials, then design and draw the drawings to determine the coupling's external dimensions and bore diameter parameters. At the same time, select the materials for each mechanism and component on the coupling and customize the corresponding dimensions.

[0075] Step 2: According to the design drawings, use a shearing machine, wire saw, mechanical cutting or laser cutting to cut the raw materials of the coupling and other required components into the corresponding size and shape to form blanks. Then, heat treat the cut blanks to improve the mechanical properties and wear resistance of the materials.

[0076] Step 3: Then, the processed blanks are processed one by one by roughing, semi-finishing and laser cutting to obtain the corresponding parts and coupling parts;

[0077] Step 4: After processing, the inner wall of the connector's claw plate is re-surfaced by fine scraping, planing, milling, or grinding to give the inner wall of the claw plate a certain friction. Then, the coupling is assembled, and the corresponding parts of multiple mechanisms are assembled accordingly. During the assembly process, the connection is fixed by laser cutting. After assembly, each mechanism is formed.

[0078] Step 5: Then, adjust the coupling and test its use after it is in conjunction with the mechanism. After the adjustment is completed, package it accordingly.
