Description

Technical Field

[0001] The invention relates to the technical field of carbon tube welding, in particular to a carbon tube welding auxiliary device for manufacturing unmanned aerial vehicles and a use method thereof. Background Art

[0002] At present, the structural design and manufacturing technology of unmanned aerial vehicles with composite materials as the core is one of the key technologies affecting the development of unmanned aerial vehicles. The structural materials of unmanned aerial vehicles should have high specific strength and specific stiffness to reduce the structural weight of the unmanned aerial vehicle and improve the flight performance. They should also have good machinability to facilitate the manufacture of required components. In order to reduce the weight of the unmanned aerial vehicle and enable the unmanned aerial vehicle to fly at high speed, a large number of carbon tubes are usually used as structural materials in the manufacture of unmanned aerial vehicles.

[0003] However, in the prior art, with the long-term use of welding auxiliary equipment, the positioning of the carbon tube is prone to instability. This instability causes the carbon tube to move or shift during the welding process, making the weld position inaccurate, thereby reducing the welding quality and causing defects such as incomplete penetration, weld nodules, and concave. In addition, due to unstable positioning, the operator needs to frequently adjust the position of the carbon tube, which not only increases the complexity of the welding operation, but also reduces the welding efficiency. What is more serious is that unstable positioning also leads to unexpected situations during the welding process, such as arc burns, gas leakage, etc., thereby increasing the safety risks of the operator. Summary of the invention

[0012] Preferably, the rotating mechanism includes a first mounting plate, a central gear is rotatably connected to the middle of the first mounting plate, the central gear is fixedly connected to the second mounting plate, racks are meshingly connected on both sides of the central gear, and sliding blocks are fixedly connected on opposite sides of the two racks, and two sliding rails are symmetrically fixedly connected to the top of the first mounting plate, and the sliding rails are slidably connected to the sliding blocks.

[0014] A method for using a carbon tube welding auxiliary device for manufacturing an unmanned aerial vehicle comprises the following steps: Step 1: Position the inner wall of the carbon tube, put the carbon tube on the outer surface of the inner support mechanism, turn the knob to drive the threaded rod to rotate, the rotation of the threaded rod drives the moving frame to move, and then the scissor-type bracket is unfolded through the second connecting frame, the unfolding of the scissor-type bracket controls the movement of the inner support plate, and the inner wall of the carbon tube is evenly supported to achieve the purpose of tightening; Step 2: Position the outer wall of the carbon tube, operate the movable handle, and the driving frame starts to rotate under the action of the linkage rod. The rotation of the driving frame drives the movable frame to rotate around the fixed axis. The rotation of the movable frame makes the mounting block and the extrusion block move, thereby extruding and positioning the outer wall of the carbon tube; Step 3: Adjust the welding position and angle of the carbon tube. The first reduction motor is running to drive the worm to rotate, and then drive the worm wheel and the rotating rod to rotate. The rotation of the rotating rod causes the second rotating frame to rotate, and the position of the inner support mechanism is changed. The second reduction motor is running to drive the rotating plate to rotate, and then the angle of the first rotating frame is adjusted. The position and angle of the carbon tube during welding can be flexibly adjusted through the rotation of the first rotating frame and the second rotating frame. Step 4: Control the position of the carbon tube. When the cylinder is running, it drives the sliding block to slide on the slide rail. The movement of the sliding block drives the rack to move, exerting force on the center gear to make it rotate. The rotation of the center gear drives another rack to move, thereby controlling the rotation of the adjustment mechanism to adjust the position of the carbon tube. The limit rods on both sides of the sliding block limit its moving position, thereby controlling the rotation angle of the center gear.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the carbon tube is sleeved on the inner support mechanism, and the threaded rod drives the moving frame to move along its length direction by turning the knob. The moving frame drives the second connecting frame, and then controls the expansion or contraction of the scissor-type bracket. The scissor-type bracket moves the inner support plate smoothly under the guidance of the guide rod and the guide hole, and holds the inner wall of the carbon tube tightly. At the same time, the external positioning mechanism rotates the driving frame through the movable handle, driving the extrusion block on the movable frame and the mounting block to extrude and position the outer wall of the carbon tube. This combination of internal and external positioning ensures that the carbon tube is stable and motionless during the welding process, thereby improving the welding quality and efficiency.

[0016] 2. In the present invention, after the first reduction motor is started, it stably drives the worm to rotate, thereby driving the worm wheel and the rotating rod to rotate synchronously. Through this mechanism, the second rotating frame can be flexibly rotated, thereby accurately adjusting the position of the internal support mechanism to ensure that the carbon tube is welded in the optimal position. In addition, the introduction of the second reduction motor further enhances the flexibility of adjustment. When the motor is running, the rotating plate drives the first rotating frame to adjust the angle. This dual rotation adjustment mechanism provides unprecedented freedom, making the adjustment of the carbon tube welding angle more precise and flexible, thereby improving the accuracy and quality of welding.

[0017] 3. In the present invention, after the cylinder is started, power is transmitted to the sliding block, driving it to slide along the slide rail. The movement of the sliding block synchronously drives the rack. Through the meshing between the teeth, the central gear starts to rotate and exerts a reverse force on the other rack, thereby driving the sliding block to move. The limit rods on both sides ensure the stability and accuracy of the sliding block, limit its moving direction and the rotation angle of the central gear. This transmission mode and adjustment mechanism improves the freedom and stability of welding, makes the carbon tube position adjustment more flexible and accurate, and adapts to different welding requirements, thereby improving welding efficiency and reliability.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example 1: Reference Figure 1 - Figure 5 As shown: a carbon tube welding auxiliary device for manufacturing unmanned aerial vehicles, comprising a device plate 1, a rotating mechanism 2 is installed on one side of the top of the device plate 1, an adjusting mechanism 3 is installed on one side of the rotating mechanism 2, and an inner supporting mechanism 5 is installed on one side of the adjusting mechanism 3; The inner support mechanism 5 includes a fixed block 51 and a sleeve 52, one end of the sleeve 52 is fixedly connected to the fixed block 51, a threaded rod 53 is rotatably connected to the inner side of the sleeve 52, one end of the threaded rod 53 is threadedly connected to a moving frame 531, and three second connecting frames 532 are fixedly connected to the outer wall of the moving frame 531, a fixed frame 521 is fixedly connected to the outer surface of the sleeve 52, and a first connecting frame 522 is fixedly connected to the outer wall of the fixed frame 521, and three scissor-type brackets 55 are arranged on the outer wall of the sleeve 52, and one side of the bottom end of the scissor-type bracket 55 is rotatably connected to the fixed frame 521, and the scissor-type bracket 55 is rotatably connected to the fixed frame 521. The other side of the bottom end of the scissor-type bracket 55 is rotatably connected to the second connecting frame 532, and an inner support plate 54 is provided on one side of the scissor-type bracket 55, and a center plate 542 is fixedly connected to the center of the inner side of the inner support plate 54, and a guide hole 541 is opened at one end of the center plate 542, and a guide rod 551 is slidably connected to the inner side of the guide hole 541, and the guide rod 551 is rotatably connected to the scissor-type bracket 55, and one end of the center plate 542 is rotatably connected to the scissor-type bracket 55, and a locking mechanism 4 is installed on one side of the inner support plate 54, and a knob 56 is installed on one side of the fixed block 51, and the knob 56 is fixedly connected to the threaded rod 53. The locking mechanism 4 includes a connecting plate 42, one end of which is fixedly connected to the inner support plate 54, a supporting frame 43 is fixedly connected to the top of the connecting plate 42, a linkage rod 44 is rotatably connected to the inner end of the supporting frame 43, a driving frame 45 is rotatably connected to the top of the linkage rod 44, and a fixed shaft 431 is fixedly connected to the other end of the inner side of the supporting frame 43, a movable frame 46 is rotatably connected to the outer surface of the fixed shaft 431, and the top of the movable frame 46 is rotatably connected to one end of the driving frame 45. A mounting block 47 is installed on the inner side of the movable frame 46, a squeezing block 41 is fixedly connected to the bottom end of the mounting block 47, and a handle 451 is fixedly connected to the top of the driving frame 45.

[0022] In this embodiment, first, the carbon tube to be welded is sleeved on the outer surface of the inner support mechanism 5. When the operator turns the knob 56, the threaded rod 53 rotates accordingly. Since there is a threaded connection between the threaded rod 53 and the moving frame 531, when the threaded rod 53 rotates, the moving frame 531 moves along the length direction of the threaded rod 53.

[0023] As the moving frame 531 moves, the second connecting frames 532 connected thereto will also move accordingly. These second connecting frames 532 are connected to the scissor-type brackets 55, and when they move, they will drive the scissor-type brackets 55 to expand or contract. The design of the scissor-type brackets 55 is similar to the cross structure of scissors, and can achieve stable expansion and contraction when subjected to external forces.

[0024] Under the coordinated action of the inner support plate 54 and the first connecting frame 522, the scissor-type bracket 55 begins to gradually unfold. This unfolding process is achieved by the sliding of the guide rod 551 inside the guide hole 541, ensuring that the inner support plate 54 can move smoothly and orderly. Since the threaded rod 53 rotates, the outer surface of the moving frame 531 has three second connecting frames 532, so the three scissor-type brackets 55 can be controlled to move together at the same time.

[0025] As the three scissor-type brackets 55 are simultaneously unfolded, the three inner support plates 54 will also move outwards accordingly to evenly support the inner wall of the carbon tube. This tightening method can not only ensure that the carbon tube remains stable during the welding process, but also improve the quality and efficiency of welding.

[0026] In addition, in order to further improve the firmness and stability of the carbon tube positioning, an external positioning mechanism is also designed. Through the movable handle 451, the driving frame 45 can start to rotate under the action of the linkage rod 44. This rotation process will drive the movable frame 46 to rotate around the fixed shaft 431. Driven by the driving frame 45, the movable frame 46 will drive the mounting block 47 to move together. Finally, the bottom end of the extrusion block 41 on the mounting block 47 will extrude and position the outer wall of the carbon tube. This combination of internal and external positioning can ensure that the carbon tube always remains stable and motionless during the welding process, thereby greatly improving the quality and efficiency of welding.

[0027] Embodiment 2: Figure 6 As shown, the adjustment mechanism 3 includes a second mounting plate 31, a support plate 34 is fixedly connected to the middle of the second mounting plate 31, a worm 321 is rotatably connected to the inner side of the support plate 34, and a rotating plate 351 is rotatably connected to both sides of the support plate 34. A first rotating frame 35 is installed on the top of the support plate 34, and both sides of the bottom of the first rotating frame 35 are fixedly connected to the rotating plate 351. A second rotating frame 36 is rotatably connected to the inner side of the first rotating frame 35, a rotating rod 38 is fixedly connected to the inner side of the second rotating frame 36, a worm wheel 37 is fixedly connected to the outer side of the rotating rod 38, and one side of the rotating rod 38 is fixedly connected to the second mounting plate 31. The worm wheel 37 is meshedly connected to the worm 321, a first reduction motor 32 is installed on one side of the top of the second mounting plate 31, and the output end of the first reduction motor 32 is fixedly connected to the worm 321, a second reduction motor 33 is fixedly connected to one side of the top of the second mounting plate 31, and the output end of the second reduction motor 33 is fixedly connected to the rotating plate 351.

[0028] In this embodiment, first, when the first reduction motor 32 is started, it will quickly and stably drive the worm 321 to rotate. The rotation of the worm 321 is not isolated, and it transmits the rotational force to the worm wheel 37. The worm wheel 37 drives the rotating rod 38 closely connected thereto to rotate synchronously. This rotational torque not only acts on the rotating rod 38, but also indirectly drives the second rotating frame 36 connected thereto to rotate.

[0029] The rotation of the second rotating frame 36 provides a flexible adjustment mechanism. By controlling the rotation angle of the second rotating frame 36, the position of the inner support mechanism 5 can be accurately adjusted, thereby ensuring that the carbon tube is in the best position during the welding process. This position adjustment not only helps the welding operation to proceed smoothly, but also improves the accuracy and quality of welding.

[0030] In addition, a second reduction motor 33 is introduced to enhance the flexibility of adjustment. When the second reduction motor 33 is running, it drives the rotating plate 351 to rotate. The rotation of the rotating plate 351 further drives the first rotating frame 35 connected thereto to adjust the angle. This dual rotation adjustment mechanism provides unprecedented freedom, so that the angle of carbon tube welding can be freely adjusted according to actual needs.

[0031] Embodiment 3: According to Figure 7 As shown, the rotating mechanism 2 includes a first mounting plate 21, a central gear 22 is rotatably connected to the middle of the first mounting plate 21, the central gear 22 is fixedly connected to the second mounting plate 31, racks 23 are meshed and connected on both sides of the central gear 22, and sliding blocks 24 are fixedly connected to the opposite sides of the two racks 23, and two slide rails 27 are symmetrically fixedly connected to the top of the first mounting plate 21, and the slide rails 27 are slidably connected to the sliding blocks 24. A cylinder 25 is installed on one side of the top of the first mounting plate 21, and the output end of the cylinder 25 is fixedly connected to a sliding block 24. Two mounting frames 26 are symmetrically fixedly connected to one side of the top of the first mounting plate 21, and a limit rod 261 is threadedly connected to the inner side of the mounting frame 26.

[0032] In this embodiment, when the cylinder 25 is started, it generates a power, which is directly transmitted to the sliding block 24 closely connected thereto, thereby driving the sliding block 24 to slide along the surface of the slide rail 27. The movement of the sliding block 24 is not isolated, and it is also connected to the rack 23, so when the sliding block 24 moves, the rack 23 also moves synchronously.

[0033] The rack 23 and the central gear 22 transmit force through precise tooth meshing. When the sliding block 24 slides on the slide rail 27, it applies a force to the central gear 22 through the rack 23, and this force causes the central gear 22 to start rotating. The rotation of the central gear 22 not only reflects the accuracy of mechanical transmission, but more importantly, it can apply a reverse force to the other rack 23 through the force generated by its rotation.

[0034] In this process, another rack 23 also starts to move due to the force. Since this rack 23 is also connected to the sliding block 24, it drives the sliding block 24 to move accordingly.

[0035] In order to ensure the stability and accuracy of the sliding block 24 during movement, limit rods 261 are set on both sides thereof. The existence of the limit rod 261 can effectively limit the movement direction of the sliding block 24 to prevent it from causing system imbalance or damage due to excessive movement. At the same time, it can also limit the rotation angle of the central gear 22 to ensure that it rotates within a certain range, thereby ensuring the stability and safety of the entire system. Through this transmission mode and adjustment mechanism, the orientation of the carbon tube can be adjusted more freely and flexibly to meet different welding requirements. This not only improves the efficiency and freedom of welding, but also makes the entire welding process more stable and reliable.

[0036] Embodiment 4: A method for using a carbon tube welding auxiliary device for manufacturing an unmanned aerial vehicle, comprising the following steps: 1) Position the inner wall of the carbon tube, sleeve the carbon tube on the outer surface of the inner support mechanism 5, turn the knob 56, drive the threaded rod 53 to rotate, the rotation of the threaded rod 53 drives the moving frame 531 to move, and then the scissor-type bracket 55 is unfolded through the second connecting frame 532, and the unfolding of the scissor-type bracket 55 controls the movement of the inner support plate 54 to evenly support the inner wall of the carbon tube, so as to achieve the purpose of tightening; 2) Positioning the outer wall of the carbon tube, operating the movable handle 451, the driving frame 45 starts to rotate under the action of the linkage rod 44, the rotation of the driving frame 45 drives the movable frame 46 to rotate around the fixed shaft 431, and the rotation of the movable frame 46 makes the mounting block 47 and the extrusion block 41 move, thereby extruding and positioning the outer wall of the carbon tube; 3) Adjust the welding position and angle of the carbon tube. The first reduction motor 32 is operated to drive the worm 321 to rotate, thereby driving the worm wheel 37 and the rotating rod 38 to rotate. The rotation of the rotating rod 38 causes the second rotating frame 36 to rotate, thereby changing the position of the inner support mechanism 5. The second reduction motor 33 is operated to drive the rotating plate 351 to rotate, thereby adjusting the angle of the first rotating frame 35. The position and angle of the carbon tube during welding can be flexibly adjusted through the rotation of the first rotating frame 35 and the second rotating frame 36. 4) Control the position of the carbon tube. When the cylinder 25 is running, it drives the sliding block 24 to slide on the slide rail 27. The movement of the sliding block 24 drives the rack 23 to move, exerts a force on the central gear 22 to make it rotate. The rotation of the central gear 22 drives another rack 23 to move, thereby controlling the rotation of the adjustment mechanism 3 to adjust the position of the carbon tube. The limit rods 261 on both sides of the sliding block 24 limit its moving position, thereby controlling the rotation angle of the central gear 22.

[0037] The method of use and working principle of the device: When welding the carbon tube, first position it. Sleeve the carbon tube on the outer surface of the inner support mechanism 5, and drive the threaded rod 53 to rotate by turning the knob 56. When the threaded rod 53 rotates, the mobile frame 531 will move accordingly. As the mobile frame 531 moves, the scissor-type bracket 55 is driven to unfold through the second connecting frame 532. Under the coordinated action of the inner support plate 54 and the first connecting frame 522, the scissor-type bracket 55 begins to unfold, and the inner support plate 54 is controlled to move by the unfolding of the scissor-type bracket 55. Since there are three second connecting frames 532 on the outer surface of the mobile frame 531 when the threaded rod 53 rotates, the three scissor-type brackets 55 can be controlled to move together. As the three scissor-type brackets 55 unfold at the same time, the guide rod 551 moves inside the guide hole 541, thereby controlling the movement of the three inner support plates 54 at the same time, so as to support the inner wall of the carbon tube, achieve the purpose of tightening, and improve the firmness and stability of positioning during welding.

[0038] When the handle 451 is moved, the driving frame 45 starts to rotate under the action of the linkage rod 44, thereby controlling the movement of the movable frame 46. The movable frame 46 rotates around the fixed shaft 431. Under the action of the driving frame 45, the movable frame 46 drives the mounting block 47 to move together, so that the bottom end of the extrusion block 41 squeezes and positions the outer wall of the carbon tube, thereby improving the firmness and stability of the carbon tube positioning.

[0039] When the first reduction motor 32 is in operation, it can drive the worm 321 to rotate, so that the worm 321 applies a force to the worm wheel 37, driving the worm wheel 37 to drive the rotating rod 38 and the second rotating frame 36 to rotate together. The rotation of the second rotating frame 36 can change the position of the inner support mechanism 5, thereby facilitating the adjustment of the position and angle of the carbon tube during welding. In addition, when the second reduction motor 33 is in operation, it can drive the rotating plate 351 to rotate, thereby driving the first rotating frame 35 to rotate, so as to adjust the angle of the first rotating frame 35. By rotating the first rotating frame 35 and the second rotating frame 36, the angle of the carbon tube during welding can be freely adjusted.

[0040] When the cylinder 25 is running, it can drive the connected sliding block 24 to move, and then control the rack 23 to move together. When the sliding block 24 slides on the surface of the slide rail 27, it will apply a force to the central gear 22, so that the central gear 22 rotates. During the rotation of the central gear 22, it will apply a force to the other rack 23, and then drive the adjustment mechanism 3 to rotate. In this way, the orientation of the carbon tube can be adjusted more freely in cooperation with the adjustment mechanism 3 to improve the efficiency and freedom of welding.

[0041] When the other rack 23 drives the connected sliding block 24 to move, both sides of the sliding block 24 are provided with limiting rods 261. The existence of the limiting rods 261 can limit the moving direction of the sliding block 24, thereby limiting the rotation angle of the central gear 22.

[0042] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
