Description

Technical Field

[0001] This invention belongs to the field of assembly tooling technology, and more specifically, relates to an auxiliary assembly tooling for landing gear. Background Technology

[0002] Landing gear auxiliary assembly fixtures are mainly used in the final assembly of medium and large-sized UAVs, typically for assisting in the installation of landing gear during the production process. These fixtures facilitate UAV production, save manpower, and improve production efficiency.

[0003] Currently, there is no equipment on the market suitable for the auxiliary assembly of landing gear for medium and large-sized drones. Existing landing gear installations mostly rely on manual lifting, requiring multiple people to work together to complete the installation, which is time-consuming and labor-intensive. If the production task is heavy, it cannot meet the assembly and production requirements of drones. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an auxiliary assembly fixture for landing gear. This fixture equips the landing gear chassis with two lifting components. One lifting component has a sliding component at its lifting end, and both the sliding end of the sliding component and the lifting end of the other lifting component are rotatably connected to locking components. The landing gear can pass through the two locking components and be locked by them. When the chassis is moved so that the landing gear is close to the UAV body, the height of the lifting ends of the two lifting components can be adjusted to align the mounting holes of the landing gear with those of the UAV body. Fasteners are then installed. After the landing gear is installed, the two locking components are loosened, the chassis is removed, and the landing gear installation is completed. This solves the problem that existing landing gear installations often rely on manual lifting, requiring multiple people to work together, which is time-consuming and labor-intensive, and cannot meet the assembly and production requirements of UAVs when production tasks are heavy.

[0040] Preferred embodiments of the invention will now be described in more detail. While preferred embodiments of the invention are described below, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0041] This invention provides a landing gear auxiliary assembly fixture, which includes at least one landing gear fixing vehicle, the landing gear fixing vehicle comprising:

[0042] Chassis;

[0043] Two lifting components are respectively located on the upper sides of the chassis;

[0044] A sliding component is disposed at the lifting end of one of the lifting components;

[0045] Two locking components are provided, one of which is rotatably connected to the lifting end of another lifting component, and the other is rotatably connected to the sliding end of a sliding component. The landing gear can be inserted into the two locking components and locked by them.

[0046] Specifically, when moving the chassis to bring the landing gear close to the UAV body, the height of the lifting ends of the two lifting components can be adjusted to align the mounting holes of the landing gear with those of the UAV body. After installing the fasteners, the two locking components are loosened and the chassis is removed, thus completing the landing gear installation. The sliding component is used to compensate for the change in distance between the two locking components caused by the change in tilt angle. This invention can meet the landing gear installation requirements in the final assembly of medium and large UAVs. Compared with traditional landing gear assembly operations, it reduces the number of operators, greatly reduces the labor intensity of workers, shortens the landing gear assembly time, reduces labor costs, and improves work efficiency.

[0047] Optionally, there are two landing gear fixing vehicles, namely a left landing gear fixing vehicle and a right landing gear fixing vehicle, which are mirror images of each other.

[0048] Specifically, since a landing gear needs to be installed on each of the left and right sides of the drone body, the two landing gears can be fixed by the left landing gear fixing vehicle and the right landing gear fixing vehicle respectively.

[0049] Optionally, it also includes a connecting structure for connecting the left landing gear fixing car and the right landing gear fixing car and fixing the relative positions of the left landing gear fixing car and the right landing gear fixing car.

[0050] Specifically, the connecting structure can connect the left landing gear fixing car and the right landing gear fixing car together to form a whole.

[0051] Optionally, the connection structure includes:

[0052] Two connecting rods, each with a round hole and a square hole at each end;

[0053] Two first lugs and two second lugs, wherein one first lug and one second lug are located on one side of the chassis of the left landing gear fixing vehicle, and the other first lug and the other second lug are located on one side of the chassis of the right landing gear fixing vehicle;

[0054] Two cylindrical pins and two square pins; one end of the connecting rod is rotatably connected to the first ear seat through a round hole and a cylindrical pin, and the other end of the connecting rod is detachably connected to the second ear seat through a square hole and a square pin.

[0055] The two connecting rods can be connected in parallel between the left landing gear fixed car and the right landing gear fixed car.

[0056] The first lug on the chassis of the left landing gear fixed vehicle has a round lug hole, and the second lug has a square lug hole.

[0057] The first lug on the chassis where the right landing gear is fixed has a round lug hole, while the second lug has a square lug hole.

[0058] The round first lug on the chassis of the left landing gear fixed vehicle corresponds to the square second lug on the chassis of the right landing gear fixed vehicle;

[0059] The square-shaped second lug on the chassis of the left landing gear fixed vehicle corresponds to the round-shaped first lug on the chassis of the right landing gear fixed vehicle;

[0060] Specifically, the length of the connecting rod can be arbitrarily selected, thereby adjusting the distance between the two landing gears. The cylindrical pin has a circular cross-section, and the square pin has a square cross-section. Since the square pin restricts the rotation of the connecting rod, it can ensure the rigid connection between the left landing gear mounting carriage and the right landing gear mounting carriage, thus ensuring the connection stability of the landing gear. After the two landing gears are fixed on the UAV body, the left and right landing gear mounting carriages can be removed to complete the docking with the UAV body. The connecting rod preferably adopts stepless adjustment to compensate for the change in the distance between the two landing gears caused by the change in the clamping position.

[0061] Optionally, the lifting assembly includes a worm gear screw jack, wherein the screw length of one worm gear screw jack is greater than the screw length of the other worm gear screw jack, and a sliding assembly is disposed on the lifting end of the screw on one side.

[0062] Specifically, the two worm gear screw jacks of the landing gear fixing car have two screws of different lengths, which are used to raise and lower the landing gear on the high side and low side respectively, to adjust the attitude of the landing gear and make the mounting holes of the landing gear align with the pre-installed flange.

[0063] Optionally, it also includes a linkage sleeve, the side wall of which is provided with an opening, and one end of the linkage sleeve is provided with an opening, both the opening and the opening being elongated in shape.

[0064] The drive shafts of the two worm gear screw jacks are set to coincide, and a linkage rod is fixedly connected to one end of each drive shaft. A linkage pin is fixedly connected to the side wall of each linkage rod.

[0065] The other end of the linkage sleeve is fitted onto one of the linkage rods, and the linkage pin on one of the linkage rods is slidably connected to the opening. When the other end of the linkage sleeve is inserted into another linkage rod, the linkage pin on the other linkage rod engages with the opening.

[0066] Specifically, the two lead screws can be raised and lowered independently to adjust the installation angle of the landing gear. Alternatively, by moving the linkage sleeve, the other end of the linkage sleeve can be inserted into another linkage rod, so that the linkage pin on the other linkage rod engages with the opening. This allows the drive shafts of the two worm gear lead screw jacks to be connected to achieve synchronous raising and lowering of the two lead screws.

[0067] Individual lifting and lowering functions are used to adjust the angle of the landing gear to ensure the docking of the landing gear and the flange. The synchronous lifting function is used to adjust the overall height of the landing gear to align the mounting holes on the flange with the mounting holes on the UAV body.

[0068] Optionally, the sliding component includes:

[0069] The tray is fixed to the lifting end of the lead screw on one side;

[0070] The slide rail is fixed to the tray.

[0071] The slider is slidably connected to the slide rail, and another locking component is rotatably connected to the slider.

[0072] Specifically, when the two lead screws rise and fall asynchronously and independently, the sliding generated by the slider on the slide rail is used to compensate for the change in distance between the two locking components caused by the change in tilt angle.

[0073] Optionally, it also includes two chuck seats, which are respectively fixed to the lifting end of another lifting component and the sliding end of a sliding component. One end of the chuck seat is hinged to a connecting block, and the two locking components are detachably connected to the other ends of the two connecting blocks.

[0074] Specifically, the locking assembly can rotate on the chuck seat via a connecting block.

[0075] Optionally, the locking assembly includes two semi-circular hoops, one of which has a threaded rod fixedly connected to the middle of its outer convex wall, and the other end of the connecting block has a threaded hole, with the threaded rod threadedly connected to the threaded hole.

[0076] The two semicircular hoops are hinged at one end and threaded at the other end. When the two semicircular hoops are fastened to the landing gear, the two threaded holes can be fixed by screws.

[0077] The inner concave wall of the semi-circular hoop is equipped with a rubber pad.

[0078] Specifically, the two semi-circular hoops can fasten the landing gear. By manually and quickly turning the screws to tighten the two semi-circular hoops, the landing gear can be quickly secured, completing the first step of securing the landing gear after unsealing. Rubber pads are used to protect the surface of the landing gear to ensure that the landing gear will not slip or rotate.

[0079] Optionally, the chassis is rectangular, and omnidirectional wheels are provided at each of the four corners of the chassis.

[0080] Specifically, the omnidirectional wheels allow the landing gear mounting vehicle to move freely on the ground, making it easier to align the mounting holes of the landing gear with the mounting holes of the drone body.

[0097] The other end of the linkage sleeve 19 is sleeved on one of the linkage rods 17. The linkage pin 18 on one of the linkage rods 17 is slidably connected to the opening. When the other end of the linkage sleeve 19 is inserted into another linkage rod 17, the linkage pin 18 on the other linkage rod 17 is engaged with the opening.

[0098] In this embodiment, the sliding component includes:

[0099] The tray 10 is fixed to the lifting end of the lead screw 9 on one side;
