[0017] Furthermore, multiple grooves are provided on the outer wall of each guide rail.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. By selecting an appropriate number of moving mechanisms and fixing them to the connecting mechanism, the moving paths of the moving mechanisms are then manually adjusted. The bracket parts are then dispersed and installed on different moving mechanisms. Individual parts can be installed on different moving mechanisms. Initially, multiple parts are in a scattered state. When assembling the parts, the moving mechanisms can be used to assemble the parts one by one. Then, a welding robot is used to automatically weld the joints of the parts, which facilitates the assembly of the bracket and forms an intelligent manufacturing island from assembly to welding.

[0020] 2. Select an appropriate number of moving mechanisms based on the parts, and then insert the locking rods on the moving mechanisms into the space between the two positioning tubes through the locking holes of the ring body. Then, screw the screws into the threaded holes on the arc plate to fix the position of the arc plate. Beforehand, manually bend the metal rods on the guide rail using a bending tool so that the guide rail forms a track with different paths as the adjacent metal rods. Then, move the locking plates on the guide rail so that multiple locking plates are distributed to facilitate the installation of parts onto the locking plates. Then, use a robotic arm in conjunction with an intelligent robot to place the parts onto the support blocks on the locking plates. After the support blocks are embedded into the matching U-shaped blocks, they are fixed with bolts so that the parts can slide between the support blocks and the U-shaped blocks. In addition, replace the U-shaped block on one of the locking components installed on the parts with a U-shaped block with a rubber abutment so that the parts are positioned by the rubber abutment.

[0021] 3. By starting the servo motor, the lead screw is rotated, causing the lead screw to move two moving plates against the drive wheel and slide along the prism through its own moving block. The drive wheel is moved to the position between any two positioning tubes. Then, by starting the drive motor, the prism and drive wheel are rotated around the connecting tube through gears, gear rings and support rods, so that the drive wheel contacts any driven wheel. By starting the power motor, the prism, drive wheel and the contacting driven wheel are rotated synchronously, so that the driven wheel pulls the pull rope and moves the adjacent clamping plate along the guide rail. This controls multiple clamping plates to move sequentially along the adjacent guide rails, so that the parts are assembled one by one.

[0022] 4. When a single part is installed on two clamping plates, only the clamping component on a single clamping plate has a U-shaped block with a rubber abutment, so that the relative positional relationship between the clamping component and the part remains unchanged, while the part can slide on other clamping components. As the clamping plates move one by one along the adjacent guide rails, the single part installed on the two clamping plates will naturally deflect and tilt, reducing interference with other parts.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and 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.

[0035] Please see Figures 1-10 In this embodiment of the invention, a welding and positioning device for a UAV tube body support includes:

[0036] The system comprises a base plate 100, two fixed tubes 200, a connecting mechanism 300 for positioning the moving mechanism 400, and multiple moving mechanisms 400 for moving and assembling the components of the tube support. The base plate 100 has a U-shaped structure, with circular holes on both arms. The two fixed tubes 200 are respectively fixedly fitted into the two circular holes. The connecting mechanism 300 is located between the two fixed tubes 200 and includes multiple positioning tubes 310 arranged horizontally in sequence. Each fixed tube 200 has a one-end sealed structure, and a connecting tube 330 is fixedly connected to one end of each fixed tube 200. The connecting tube 330 passes through the interior of multiple positioning tubes 310. A column 331 is fixedly connected between the inner wall of any positioning tube 310 and the outer wall of the connecting tube 330. Both ends are fixedly sleeved with ring bodies 320. Annular grooves 321 are opened on the adjacent sides of the two ring bodies 320 on any positioning tube 310. Multiple moving mechanisms 400 are movably connected to the connecting mechanism 300. Each moving mechanism 400 is located between two adjacent positioning tubes 310. The moving mechanism 400 includes an arc plate 410, and both ends of the arc plate 410 are fixedly connected with locking rods 411. Both locking rods 411 are L-shaped, and the short arms of the two locking rods 411 are slidably locked into the interior of two adjacent annular grooves 321. A guide rail 420 is fixedly connected to one side of the arc plate 410, and metal rods 421 are fixedly connected to both sides of the guide rail 420. One end of each metal rod 421 is fixedly connected to one side of the arc plate 410. A locking plate 430 is slidably locked inside each guide rail 420.

[0037] Specifically, by placing the U-shaped base plate 100 on the ground, and then selecting an appropriate number of moving mechanisms 400 according to the complexity of the tubular support assembly, the tubular components constituting the tubular support can be fixed to the clamping plates 430 on different moving mechanisms 400 during the welding process. If some components are too long or have a complex shape, different parts of the components can be fixed to the clamping plates 430 on different moving mechanisms 400, so that a single component is fixed to the clamping plates 430 on one or two moving mechanisms 400. The position is fixed on 0, and then the metal rod 421 on the moving mechanism 400 is bent using existing bending equipment. The guide rail 420 is made of rubber, a soft material, so that the guide rail 420 will deform synchronously with the bending of the adjacent metal rod 421, and the deformed guide rail 420 provides a moving path for its internal clamping plate 430. The bending of the metal rod 421 can be adjusted manually to control the moving path of the clamping plate 430 inside different guide rails 420. When the parts are installed on the clamping plate 430, different parts... The paths of adjacent guide rails 420 are different, and the positions of the clamping plates 430 on the guide rails 420 are different and staggered, which facilitates the installation of parts. Then, during bracket assembly, the clamping plates 430 on multiple moving mechanisms 400 can be moved along the paths formed by adjacent guide rails 420, and the clamping plates 430 on each moving mechanism 400 move sequentially. This allows different parts to move sequentially along the connected clamping plates 430, allowing the different parts to be sequentially assembled into a bracket. The assembled bracket is positioned above multiple positioning tubes 310, and then a welding robot or human is used. The workers weld the joints of the assembled bracket parts to fix them in place. Then, the parts are removed from the clamping plate 430, and the welded bracket is hoisted and pulled away from the base plate 100. When constructing the path formed by the guide rail 420, care should be taken to ensure that the path of the guide rail 420 does not affect the removal of the welded bracket. The two arms of the base plate 100 are of unequal length, so that the welded bracket can be pulled away from the base plate 100 from the shorter arm during hoisting, which facilitates the splicing and positioning of the bracket.

[0038] Example 1

[0039] like Figures 3-6 As shown, in this embodiment, a bayonet 322 is provided at the bottom of the outer side wall of any ring 320, multiple threaded holes are provided on one side of any arc plate 410, a positioning block 431 is fixedly connected to one side of any clamping plate 430, multiple insertion holes are provided on the outer side wall of any positioning block 431, and a locking component is provided for each positioning block 431. The locking component includes:

[0040] The support block 440 and the U-shaped block 441 are provided. The bottom of the support block 440 is fixedly connected with a plug rod, which is movably inserted into the interior of the adjacent plug hole. The outer wall of the plug rod is provided with a thread for engaging the nut. The bottom of the support block 440 is provided with a through hole for connecting bolts. The two arms of the U-shaped block 441 are provided with multiple connecting holes for connecting bolts. The support block 440 is movably embedded between the two arms of the U-shaped block 441. The top surface of the U-shaped block 441 is provided with a rectangular groove.

[0041] In this embodiment, a slot 322 is provided on the ring body 320. The short arms of the two locking rods 411 on any arc plate 410 can be inserted into or disengaged from the adjacent annular groove 321 through the slot 322. This allows the number of moving mechanisms 400 between the two positioning tubes 310 to be increased or decreased as needed. When the arc plate 410 of the moving mechanism 400 installed on the two adjacent positioning tubes 310 needs to be fixed in position, screws can be screwed into the threaded holes so that the screws abut against the adjacent ring body 320 to fix the position of the arc plate 410.

[0042] In this embodiment, the parts can be mounted on the mounting plate 430 using a dedicated clamping assembly. During the mounting process, the clamping assembly can be configured with different specifications and models as needed. For example, V-shaped supports 440 can be used to position square tubes, and arc-shaped supports 440 can be used for round pipes. Some U-shaped blocks 441 have rubber abutments fixedly connected inside their rectangular grooves to secure the parts. The inserts on different specifications and models of supports 440 have the same specifications. First, a suitable support 440 is selected based on the size and shape of the part. Then… Insert the insert rod on the support block 440 into the insertion hole at the appropriate position on the adjacent positioning block 431, and then screw the nut onto the insert rod so that the support block 440 can rotate freely on the adjacent positioning block 431. Then, place the part on the support block 440, and then use the support block 440 to embed the matching U-shaped block 441 so that the U-shaped block 441 and the support block 440 limit the part. Finally, pass the bolt through the connecting hole on the U-shaped block 441 and the through hole on the support block 440 and screw it onto the nut to complete the installation. The part can slide between the U-shaped block 441 and the support block 440.

[0043] When a single part is mounted on a single clamping plate 430, the U-shaped block 441 on the clamping plate 430 can be replaced with a U-shaped block 441 with a rubber abutment. When a single part is mounted on two clamping plates 430, the U-shaped block 441 on one of the clamping plates 430 can be replaced with a U-shaped block 441 with a rubber abutment, so that the rubber abutment abuts against the part, preventing the part from rotating and positioning the part. When the two clamping plates 430 move sequentially, the part is in a fixed state with the U-shaped block 441 with the rubber abutment, and the part can slide at the U-shaped block 441 without the rubber abutment. Thus, when the two clamping plates 430 move sequentially, the part can form different tilt states due to the movement order of the two clamping plates 430, so as to reduce interference with other parts.

[0044] like Figures 4-5 As shown, in this embodiment, two support plates are fixedly connected to the other side of any arc-shaped plate 410. A driven wheel 460 is rotatably connected between the two support plates on any arc-shaped plate 410. A pull rope 432 is provided for each clamping plate 430. Both ends of each pull rope 432 pass around the adjacent driven wheel 460 and through the adjacent arc-shaped plate 410. Both ends of each pull rope 432 are fixedly connected to the ends of the adjacent clamping plate 430. Two fixing plates 450 are fixedly connected to the bottom surface of any guide rail 420. The tops of the two fixing plates 450 on any guide rail 420 are fixedly connected... Each guide rail 420 has a support plate, and each of the two fixed plates 450 on any guide rail 420 has a groove on one side of each adjacent plate. Each of the two fixed plates 450 on any guide rail 420 has a stop wheel 451 between them. The axle of each stop wheel 451 is slidably connected to the inside of the two adjacent grooves. Each of the two fixed plates 450 on any guide rail 420 has two guide rollers 452 rotatably connected between them. Each pull rope 432 passes around two adjacent guide rollers 452 and adjacent stop wheels 451. Each support plate is fixedly connected to a spring 453. Each spring 453 is in contact with the adjacent stop wheel 451.

[0045] In practice, the pull rope 432 can be kept taut when the guide rail 420 is deformed by the abutment wheel 451 and the rebound spring 453. Then, by rotating the driven wheel 460, the pull rope 432 can be driven to pull the clamping plate 430 along the guide rail 420. The clamping plate 430 is made of soft materials such as silicone and plastic, so that the clamping plate 430 can be pulled and moved by the pull rope 432 inside the deformed guide rail 420. The driven wheel 460 has an annular groove for embedding the pull rope 432, and the groove has a toothed structure for piercing the pull rope 432 to pull the pull rope 432 to move, thus maintaining the transmission stability between the driven wheel 460 and the pull rope 432.

[0046] like Figures 7-10As shown, in this embodiment, a lead screw 340 is rotatably connected to one end of a fixed tube 200, and the lead screw 340 is located inside a connecting tube 330. The lead screw 340 is equipped with two moving blocks. A guide groove is formed on the outer wall of the connecting tube 330, and two moving plates 341 are slidably engaged inside the guide groove. The two moving plates 341 are respectively fixedly sleeved with the two moving blocks on the lead screw 340. A rotating ring 210 is rotatably connected to one end of a fixed tube 200, and a prism 350 is rotatably connected to one side of the rotating ring 210. A drive wheel 351 is slidably sleeved on the outer wall of the prism 350, and the drive wheel 351 is located between the two moving plates 341. The prism 350 is located outside the connecting tube 330. A toothed ring 110 is rotatably connected to one side of one arm of the base plate 100. A support rod is fixedly connected to the inner wall of 110. One end of the prism 350 is rotatably connected to one end of the support rod, and a power box 352 is fixedly connected to one end of the support rod. A power motor is installed inside the power box 352, and the motor shaft of the power motor passes through the support rod and is fixedly connected to the prism 350. A gear 120 is rotatably connected to one side of the base plate 100, and the gear 120 meshes with the gear ring 110. A connecting shell 130 is fixedly connected to one side of the base plate 100, and a motor box 131 and a drive box 132 are fixedly connected to one side of the connecting shell 130. A servo motor is installed inside the motor box 131, and the motor shaft of the servo motor is fixedly connected to one end of the lead screw 340. A drive motor is installed inside the drive box 132, and the motor shaft of the drive motor is fixedly connected to the axle of the gear 120.

[0047] In specific implementation, the lead screw 340 is a ball screw 340 as in the prior art. Starting the servo motor drives the lead screw 340 to rotate, thereby causing the lead screw 340 to drive two moving plates 341 to move synchronously via its own moving block. The two moving plates 341 can abut against the drive wheel 351 and slide along the prism 350, allowing the drive wheel 351 to move between any two positioning tubes 310. Then, starting the drive motor drives the gear ring 110 to rotate via the gear 120, causing the gear ring 110 to drive the prism 350 and the drive wheel 351 to rotate around the connecting tube 330 via the support rod, causing the drive wheel 351 to contact any driven wheel 460. The surfaces of both the drive wheel 351 and the driven wheel 460 are covered with abrasive material to increase friction and improve transmission stability. The power motor drives the prism 350 to rotate, causing the prism 350 to drive the drive wheel 351 and the driven wheel 460 in contact to rotate synchronously. This causes the driven wheel 460 to pull the rope 432, which in turn moves the adjacent clamping plate 430 along the guide rail 420. The servo motor is equipped with an electromagnetic brake, so that the motor shaft will not rotate when the servo motor is not started. The start and stop of the drive motor, servo motor and power motor can be controlled by different controllers. The existing robotic arm can be used to place the parts onto the appropriate clamping plate 430. Then, the existing intelligent robot is used to tighten the screws on the clamping components, making the bracket assembly process more intelligent. Finally, the welding robot is used to automatically weld the parts that need to be welded, thus forming an intelligent casting island from the assembly of bracket parts to the welding of the bracket.

[0048] Example 2

[0049] Based on Embodiment 1, grooves are provided to facilitate the deformation of guide rail 420.

[0050] like Figure 4 As shown, in this embodiment, multiple grooves are provided on the outer wall of any guide rail 420.

[0051] In practice, multiple grooves are provided on the outer wall of the guide rail 420, making the wall thickness of the grooves of the guide rail 420 thinner. The guide rail 420 is made of soft materials such as rubber, so that the thinner part of the guide rail 420 can be naturally stretched to adapt to the deformation of the metal rod 421 when the guide rail 420 is deformed.

[0052] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0053] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
