The pipe fitting fixing mechanism consists of a base support component and an outer diameter fixing component. Among them, the outer diameter fixing component is provided with a through hole for fixing the pipe fitting, and is used to fix the outer diameter of the pipe fitting extending into the through hole. The base support component includes a limit card member passing through the through hole. When the pipe fitting extends into the through hole, the rotation of the pipe fitting in the through hole is restricted by the cooperation of the limit card member and the limit groove of the pipe fitting.

Description

Technical Field

[0001] The present application relates to the field of mechanical fixing devices, and in particular to a pipe fixing mechanism, a pipe fixing method and a drone. Background Art

[0002] During the flight of the drone, the power system can control the rotation of the propellers to provide lift for the fuselage to fly upward. However, the rotation of the propellers also causes the drone to vibrate in all directions, resulting in poor fuselage stability.

[0003] Drones are usually equipped with various pipes that support the structure, such as hollow carbon tubes that support the arms. Therefore, ensuring the stability of the installation of each pipe is extremely important for the overall stability of the drone.

[0004] At present, when fixing and installing pipe fittings, it is usually adopted Figure 1 The principle of the three-jaw chuck shown is to fix the pipe fitting.

[0005] However, the pipe will be excited to produce vibration modes along the torsional direction during the flight of the aircraft. The pipe is still easy to rotate when fixed by the chuck, thereby reducing the stiffness in this direction and causing some vibration problems. Summary of the invention

These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of this specification, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information.

[0062] Figure 2 The present invention provides a schematic diagram of the structure of a pipe fixing mechanism provided in an embodiment of the present specification, and the pipe fixing mechanism is composed of an outer diameter fixing component 1 and a base support component 2. The outer diameter fixing component 1 is provided with a through hole, which can be used to fix the outer diameter of the pipe. The base support component 2 includes a limit clamp 20, which is in the shape of a flat plate and passes through the through hole. When the pipe is inserted into the through hole, the limit clamp 20 can cooperate with the limit groove on the pipe to limit the freedom of rotation of the pipe in the axial direction, thereby improving the stability of the pipe installation.

[0063] When the pipe fixing mechanism shown in this manual is used to fix the pipe, a limiting groove may be pre-processed on the end side of the pipe, such as Figure 3 As shown, when the pipe is a hollow pipe, a symmetrically distributed groove, i.e., a limit groove 40, is processed at one end of the pipe. When the pipe is fixed by the pipe fixing mechanism, the limit groove 40 on the pipe can be aligned with the limit clamp 20, so that the limit groove 40 on the pipe is clamped with the limit clamp 20 to limit the torsion of the pipe in the through hole. The width of the upper limit groove 40 on the pipe is slightly larger than the width of the limit clamp 20.

[0064] Further, in this specification, the outer diameter fixing component 1 can be composed of a flexible hinge 10, such as Figure 4 As shown, the outer wall side of the flexible hinge 10 is semicircular, and the inner wall side is arc-shaped. When not subjected to external force, the flexible hinge 10 is in a closed state, and its inner wall side forms a circular through hole, into which the outer diameter of the pipe can be inserted, and the diameter of the through hole is equal to the outer wall diameter of the pipe. The flexible hinge 10 also has an opening, and when stretched outward from the opening, the flexible hinge 10 opens, making it easier for the pipe to extend into the through hole.

[0065] In order to tighten the outer diameter of the pipe, a fastening hole 12 is also provided on the side wall of the flexible hinge 10. When the flexible hinge 10 is closed, the first fastening bolt 11 of the outer diameter fixing component 1 can pass through the flexible hinge 10 through the fastening hole 12 on the side wall to lock the flexible hinge 10.

[0066] Of course, in other embodiments of the present specification, the outer wall side of the flexible hinge 10 may also be designed to be other shapes, such as a rectangular shape. The present specification does not impose any limitation on this and it may be set as needed.

[0067] In order to support the pipe fitting, the base support component 2 further includes a base 21 for supporting the flexible hinge 10 and the limit clamp 20. One end of the limit clamp 20 is connected to the inner wall bending part of the flexible hinge 10, so that the flexible hinge 10 surrounds the limit clamp 20 from both sides of the bending part, and the other end extends from the closed part of the flexible hinge 10 and is connected to the base 21.

[0068] Since the width of the limit card 20 is usually narrow, in order to enhance stability, the contact area between the flexible hinge 10 and the base 21 can be increased. Therefore, the base 21 can be set to a convex structure, such as Figure 5 As shown, the limit clamp 20 is connected to the top of the convex character of the base 21. When the flexible hinge 10 is closed, the flexible hinge 10 and the base 21 are tightly fitted.

[0069] In one embodiment of the present specification, a transversely penetrating fastening hole 12 is provided at the fitting portion between the flexible hinge 10 and the base 21. When the flexible hinge 10 is closed, the fastening hole of the flexible hinge 10 is aligned with the fastening hole of the base 21, and the first fastening bolt 11 can be passed through the aligned fastening hole 12 to lock the flexible hinge 10 on the base 21.

[0070] Furthermore, the inner wall of the fastening hole 12 has a thread matching the first fastening bolt 11, and the first fastening bolt 11 can be rotated in the fastening hole, pass through the flexible hinge 10 and the base 21 on the left, and at least rotate into the fastening hole of the flexible hinge 10 on the right, so as to lock the flexible hinge 10 and the base 21.

[0071] Alternatively, the inner wall of the fastening hole 12 is a smooth inner wall, and the first fastening bolt 11 passes through the flexible hinge 10 and the base 21, passes through the side wall on the other side of the flexible hinge 10, and is tightened with a matching nut to lock the flexible hinge 10 on the base 21.

[0072] In another embodiment of the present specification, there are two first fastening bolts 11, which respectively pass through the fastening holes on the left side wall of the flexible hinge 10 to lock the left flexible hinge 10 on the base 21, and pass through the fastening holes on the right side wall of the flexible hinge 10 to lock the right flexible hinge 10 on the base 21. The inner wall of the fastening hole has threads matching the first fastening bolts 11, and there are also aligned fastening holes on the left and right sides of the middle base 21.

[0073] In order to enhance the stability of the support of the base 21 , a reinforcing rib 22 is provided at the connection between the vertical surface and the horizontal surface of the base 21 to avoid shaking.

[0074] In practical applications, some mechanical equipment needs to be equipped with a pipe structure to assume structural support or other auxiliary functions. Therefore, in order to improve the stability of the pipe installation on the mechanical equipment, the pipe fixing mechanism provided in this specification can be used to fix the pipe fixing mechanism on the target equipment, and then fix the pipe through the pipe fixing mechanism. Therefore, an external mounting hole is also provided on the pipe fixing mechanism to fix the pipe fixing mechanism on the target equipment.

[0075] Among them, the target equipment needs to install pipe fittings and has high requirements on the stability of pipe fitting installation, such as drones, ships and mechanical processing equipment.

[0076] like Figure 6a As shown, the external mounting hole 13 can be set on the flexible hinge 10, and the pipe fixing mechanism also includes a third fastening bolt, which can pass through the external mounting hole 13, through the pipe fixing mechanism and the target device, and fix the pipe fixing mechanism on the target device.

[0077] like Figure 6b As shown, the external mounting hole 24 can also be set on the bottom surface of the base 21, and the third fastening bolt can pass through the external mounting hole 24, through the pipe fixing mechanism and the target device, and through tightening the nut matched with the other end, the pipe fixing mechanism is fixed to the target device. Among them, this specification does not limit the number and specific position of the external mounting holes.

[0078] In one embodiment of the present specification, the limit clamp 20 can also be divided into a first sub-limit clamp 201 and a second sub-limit clamp 202. Figure 7 As shown, one end of the first sub-limiting card 201 is connected to the inner wall side of the flexible hinge 10, and one end of the second sub-limiting card 202 is connected to the base 21, and the sum of the lengths of the first sub-limiting card 201 and the second sub-limiting card 202 is equal to the aperture of the through hole.

[0079] When the flexible hinge 10 is closed, the first sub-limiting clamp 201 is connected to the second sub-limiting clamp 202, and passes through the through hole formed by the flexible hinge 10. In order to improve the connection tightness, the connection between the first sub-limiting clamp 201 and the second sub-limiting clamp 202 can be set to a wedge shape.

[0080] Furthermore, in other embodiments of the present specification, the pipe fixing mechanism may also be provided with a plurality of limit clamps 20 penetrating through the through holes. When there are two limit clamps 20, one end of the first limit clamp is connected to the base 21, and one end is connected to the inner wall side of the flexible hinge 10, and the second limit clamp is fixedly connected to the first limit clamp through the central axis to form an X shape. When the flexible hinge 10 is closed, the two ends of the second limit clamp fit the inner wall side of the flexible hinge 10.

[0081] Alternatively, one end of the first limit card is connected to the base 21, and one end is connected to the inner wall side of the flexible hinge 10, and the second limit card is divided into a first sub-limit card and a second sub-limit card. One end of the first sub-limit card is connected to the inner wall side of the flexible hinge 10, and one end of the second sub-limit card is connected to the inner wall side of the flexible hinge 10. When the flexible hinge 10 is closed, the first sub-limit card and the second sub-limit card are connected to the central axis of the first limit card.

[0082] This specification does not limit the number of the limiting clamps 20. Similarly, the pipe to be fixed also has a plurality of corresponding limiting grooves that fit with the limiting clamps 20.

[0083] In addition, this specification also provides a structural schematic diagram of a pipe fixing mechanism, such as Figure 8 As shown, the outer wall side of the flexible hinge 10 in the pipe fixing mechanism is rectangular, and the base 21 is in the shape of a cube. Figure 3 and Figure 7 The shape of the outer wall of the flexible hinge 10 and the shape of the base 21 are merely exemplary representations, and this specification does not impose any limitations thereto, and they may be set according to specific needs.

[0084] In one embodiment of the present specification, since the pipe fitting and its installation method will affect the overall vibration performance and reliability of the target device, the pipe fitting needs to be performance tested before being installed to the target device. For example, the elastic modulus of the pipe fitting can be determined by testing the vibration frequency of the pipe fitting under different stress conditions.

[0085] In order to facilitate the performance test of the pipe fitting, the pipe fitting fixing mechanism is also provided with components for performing the performance test of the pipe fitting, such as a weight component that can change the stress condition of the pipe fitting in the torsional direction.

[0086] like Fig. 9As shown, the counterweight component 3 is composed of a first counterweight rod 30, a second counterweight rod 31 and a counterweight object. One end of the first counterweight rod 30 is connected to the base 21, and one end of the second counterweight rod 31 is connected to the flexible hinge 10. The center line of the first counterweight rod 30, the center line of the limit clamp 20 and the center line of the second counterweight rod 31 are on a straight line, and the first counterweight rod 30 and the second counterweight rod 31 are symmetrically distributed on the left and right sides.

[0087] Furthermore, in order to adjust the stress condition of the pipe fitting in the torsional direction, a through hole groove 34 is provided on at least one of the first counterweight rod 30 and the second counterweight rod 31, so that the stress condition of the pipe fitting in the torsional direction can be changed by adjusting the position of the counterweight object in the through hole groove 34.

[0088] Fig. 9 In the exemplary embodiment, through-hole grooves are provided on the first counterweight rod 30 and the second counterweight rod 31. The counterweight objects on the pipe fixing mechanism can be configured according to the actual load condition of the pipe on the target equipment, so that the vibration performance of the pipe can be tested under the same load condition.

[0089] In one embodiment of the present specification, the counterweight object is composed of a counterweight screw 36 and a counterweight nut 37. The counterweight screw 36 is passed through the through hole slot 34 and is tightened with the counterweight nut 37 below. The torque applied to the pipe fitting is adjusted by sliding the counterweight object in the through hole slot 34.

[0090] Furthermore, in order to more accurately adjust the torque on the pipe, a scale 35 representing the length is provided at the position corresponding to the through hole slot 34 on the counterweight rod, so that the counterweight object can be slid to a precise position according to the position of the actual load on the pipe. A partition can also be provided in the middle of the through hole slot 34 to divide it into two through hole slots 34 to enhance the supporting strength of the counterweight rod.

[0091] In addition, when the flexible hinge 10 is opened, the right connecting shaft contracts, causing the second counterweight rod 31 on the right to tilt. Therefore, in order to strengthen the support degree on the right side, a reinforcement module 32 is also provided at one end of the second counterweight rod 31. The reinforcement module 32 is distributed on both sides of the upper and lower parts of the connection between the second counterweight rod 31 and the flexible hinge 10, and can be welded on the second counterweight rod 31.

[0092] The reinforcement module 32 and the flexible hinge 10 are provided with corresponding transverse fastening holes. When the flexible hinge 10 is closed, the fastening hole of the reinforcement module 32 on the second counterweight rod is aligned with the fastening hole on the flexible hinge 10, and the second fastening bolt 33 of the outer diameter fixing component 1 can pass through the reinforcement module 32 and the flexible hinge 10 to fasten the connection between the flexible hinge 10 and the second counterweight rod 31, thereby strengthening the support degree on the right side. The inner wall of the fastening hole is provided with a thread matching the second fastening bolt 33.

[0093] Moreover, the first counterweight rod 30 on the left side can also be fixedly connected to the base 21 by welding, so the first fastening bolt 11 of the outer diameter fixing component 1 passes through the fastening hole passing through the base 21 and the flexible hinge 10, which can strengthen the support for the left support rod. In addition, screwing the first fastening bolt 11 into the fastening hole passing through the base 21 and the flexible hinge 10 can drive the upper pressure pipe part of the pipe fitting to rotate counterclockwise, and the lower pressure pipe part of the pipe fitting to rotate clockwise, so as to tighten the end of the pipe fitting extending into the through hole by pre-tightening force. Among them, the limit clamp 20 divides the pipe fitting into the upper pressure pipe part and the lower pressure pipe part.

[0094] When testing the performance of pipe fittings, the following methods can be used: Figure 4 The pipe fixing mechanism A shown in FIG. Fig. 9 The pipe fixing mechanism B shown fixes both ends of the pipe.

[0095] Take the horizontal placement of pipe fittings as an example. Fig.10a As shown, one end of the pipe can be installed on the pipe fixing mechanism A and the other end on the pipe fixing mechanism B according to the arrow direction in the figure. One end of the pipe is inserted into the through hole formed by the flexible hinge 10 of the pipe fixing mechanism A, and the limiting groove 40 on the pipe is matched with the limiting clamp 20, and then the flexible hinge 10 is locked by the first fastening bolt 11 in the horizontal direction.

[0096] The other end of the pipe is inserted into the through hole formed by the flexible hinge 10 of the pipe fixing mechanism B, and the limiting groove 40 on the pipe is matched with the limiting clamp 20, and then the flexible hinge 10 is locked by the first fastening bolt 11 in the vertical direction, and the second fastening bolt 33 in the horizontal direction passes through the fastening hole aligned with the second counterweight rod 31 and the flexible hinge 10 to strengthen the supporting strength of the second counterweight rod 31. After that, the counterweight screw 36 is installed at the scale position corresponding to the actual load of the pipe, and is tightened with the counterweight nut 37 below.

[0097] Fig.10bThe figure is a schematic diagram of fixing a pipe by a pipe fixing mechanism. When testing the vibration performance of the torsional vibration of the pipe, the vibration sensor 5 used for testing can be attached to the other end away from the pipe fixing mechanism B. Afterwards, the pipe is rotated in the axial direction by striking the counterweight screw 36 or the end of the counterweight rod on the pipe fixing mechanism B, and the response data of the pipe after being excited is collected by the vibration sensor 5, so as to determine the vibration performance of the pipe based on the response data.

[0098] based on Figure 2 The pipe fixing mechanism shown in the figure is composed of a base support component and an outer diameter fixing component. The outer diameter fixing component is provided with a through hole for fixing the pipe, which is used to fix the outer diameter of the pipe inserted into the through hole. The base support component includes a limit clamp penetrating the through hole. When the pipe is inserted into the through hole, the limit clamp cooperates with the limit groove of the pipe to limit the torsion of the pipe in the through hole. The limit clamp limits the rotation angle of the pipe, thereby improving the stability of the pipe installation.

[0099] In addition, the pipe fixing mechanism in the present specification tightens the outer diameter of the pipe through the through hole formed by the flexible hinge 10. Since the clamping process is a surface contact between the inner wall of the through hole and the outer wall of the pipe, there is no stress concentration point. Compared with the method of using radially moving movable claws in the prior art, the force is more balanced, reducing the phenomenon of deformation or damage of the pipe due to stress during tightening.

[0100] Based on the pipe fixing mechanism shown above, this specification also provides a method for fixing the pipe using the pipe fixing mechanism. The technical solutions provided by each embodiment of the present application are described in detail below in conjunction with the accompanying drawings.

[0101] Fig.11 The schematic diagram of a pipe fixing method provided in the embodiment of the present specification uses a pipe fixing mechanism to fix the pipe. The pipe fixing mechanism is composed of a base support component 2 and an outer diameter fixing component 1, and a limiting groove 40 is provided on the end side of the pipe to be fixed.

[0102] Specifically, when fixing the pipe fitting, the limiting groove 40 at one end of the pipe fitting can be aligned with the limiting clamp 20 of the base support component 2, and when the pipe fitting extends into the through hole of the outer diameter fixing component 1, the outer diameter of the pipe fitting is fixed, and the limiting groove 40 of the pipe fitting cooperates with the limiting clamp 20 to limit the pipe fitting from twisting in the through hole. The limiting clamp 20 runs through the entire through hole.

[0103] Furthermore, the outer diameter fixing component 1 includes a flexible hinge 10 and a first fastening bolt 11, such as Fig.12As shown, when the flexible hinge 10 is closed, a through hole for fixing the pipe is formed, and a transversely penetrating fastening hole is provided at the fitting portion between the flexible hinge 10 and the base support component 2. When fixing the pipe, the flexible hinge 10 can be first stretched outward along the opening to open the flexible hinge 10, and one end of the pipe is inserted so that the limit clamp 20 that passes through the through hole is embedded in the limit groove 40 at one end of the pipe. Afterwards, the flexible hinge 10 is closed inward along the opening to close the flexible hinge 10 to form a through hole. Finally, the first fastening bolt 11 is passed through the transversely penetrating fastening hole between the flexible hinge 10 and the base support component 2 to lock the flexible hinge 10 so that the flexible hinge 10 fastens the outer diameter of the pipe inserted into the through hole.

[0104] It should be noted that the detailed structure of the pipe fixing mechanism has been described above, and will not be repeated in this specification. Please refer to the above content.

[0105] Since drones are usually equipped with various pipes that bear structural support, such as the rotor arms and landing gear of drones, and the drones vibrate during flight, causing the body to be unstable, the pipe fixing mechanism provided in this manual can be used to strengthen the fixing of the pipes, thereby ensuring the overall stability of the body.

[0106] Therefore, based on Figure 2 The pipe fixing mechanism shown in the figure, the embodiment of this specification also provides a corresponding drone, which can use the above-mentioned pipe fixing mechanism to fix its own functional pipes.

[0107] Fig.13 This is a schematic diagram of the structure of a drone provided in this specification, which consists of a fuselage 60, a plurality of pipes 64 and a pipe fixing mechanism 62. The dotted circle indicates the position of the pipe fixing mechanism 62 on the drone, and the solid circle is an enlarged schematic diagram of the pipe fixing mechanism 62.

[0108] On the UAV, each pipe 64 corresponds to a pipe fixing mechanism 62, which is used to fix the pipe 64 on the fuselage 60 of the UAV. The pipes 64 to be fixed on the UAV include at least one of a rotor pipe and a landing gear pipe. The two pipes 64 on the top in the figure are rotor pipes, and the two pipes 64 on the bottom are landing gear pipes.

[0109] Furthermore, the end side of the pipe 64 connected to the pipe fixing mechanism 62 is pre-processed with a limiting groove 40, and the pipe fixing mechanism is composed of an outer diameter fixing component 1 and a base support component 2, such as Figure 2As shown. For each pipe 64 on the drone, the pipe 64 can be inserted into the through hole of the outer diameter fixing component 1 to fix the outer diameter of the pipe 64. When the pipe 64 is inserted into the through hole, the limiting clamp 20 on the base support component 2 cooperates with the limiting groove 40 of the pipe 64 to limit the rotation of the pipe 64 relative to the fuselage 60.

[0110] Furthermore, a third fastening bolt is also provided on the pipe fixing mechanism 62 , and the third fastening bolt can pass through the pipe fixing mechanism 62 and the fuselage 60 of the UAV to fix the pipe fixing mechanism 62 on the fuselage 60 .

[0111] In one embodiment of the present specification, one end of the rotor tube on the drone usually needs to be connected to the drone body, and the other end is used to support load equipment, such as a camera, a motor, etc. Therefore, the other end of the rotor tube can be used as follows Fig. 9 The pipe fixing mechanism 62 shown is used to install the load device as a counterweight object on the counterweight rod to limit the rotation of the load device relative to the rotor pipe.

[0112] When torsional vibration occurs during the flight of the UAV, the limiting groove 40 on the pipe 64 is engaged with the limiting clamp 20 on the pipe fixing mechanism 62 to limit the torsion angle of the pipe 64, thereby improving the overall stability of the body and reducing safety risks.
