Abstract
Description
Technical Field
[0001] This invention relates to the field of UAV wing pivot processing technology, specifically a positioning and guiding device for UAV wing pivot cutting. Background Technology
[0002] UAV wing pivot cutting is a precise length-fixed cutting process for the axial dimension of the pivot. The core objective is to process the pivot blank to the designed axial length tolerance range, ensuring the assembly compatibility of the pivot with the wing and fuselage, and providing a stable dimensional reference for wing folding and rotation. Different cutting processes are selected for pivots made of different materials: metal pivots are preferentially cut using CNC abrasive wheel cutting or laser precision cutting. Abrasive wheel cutting uses a high-speed rotating diamond abrasive wheel to feed along the axial direction to achieve burr-free cutting; laser cutting uses a high-energy laser beam focused on the position to be cut on the blank, and completes the fixed-length cut through local melting and vaporization.
[0003] When cutting a rotating shaft to a fixed length, workers need to repeatedly install and disassemble the longer shaft. By moving the shaft that has lost its limit, the cutting point is positioned below the cutter, and then it is fixed. Since the longer shaft needs to be divided into multiple segments, workers need to repeatedly position, disassemble, and push the shaft. This positioning method not only affects the cutting efficiency but also increases the labor intensity of the workers. Summary of the Invention

One end of the positioning ring is provided with a second lead screw that passes through the movable ring. A U-shaped splicing block is installed at the end of the movable plug near the center of the positioning ring.

[0010] As a further embodiment of the present invention: the center of the disc is coaxial with the center of the guide roller, and the center of the disc is misaligned with the center of the shift pin.
[0011] As a further embodiment of the present invention: the locking unit includes a connecting compartment installed at the end of the movable frame away from the connecting ring, a pin extending to the inner side of the movable frame is inserted into the connecting compartment, a limiting groove located outside the pin is opened on the inner side of the movable frame, a stop plate is installed at one end of the pin, a second contact piece is installed at the other end of the pin on the inner side of the connecting compartment, a first contact piece is installed on the inner wall of the connecting compartment on one side of the second contact piece, a locking hole is opened on the pin, a second telescopic spring connected to the inner wall of the connecting compartment is provided on one side of the locking hole, a locking pin extending to the inside of the connecting compartment is inserted into the outer wall of the connecting compartment, and a first telescopic spring connected to the locking pin is provided on the outer wall of the connecting compartment.

By setting limit connectors and locking units, the rotation of the second lead screw causes the movable ring to move relative to the positioning ring, thereby bringing the guide clamping roller into contact with the rotating shaft to be cut. Then, the rotating shaft is pushed further, so that one end of the rotating shaft contacts the side of the movable frame away from the connecting ring. At the same time, the guide clamping roller moves the positioning slide rail through the disc and the shift pin. The locking unit operates to lock the guide clamping roller, preventing the guide clamping roller from rotating relative to the U-shaped splicing block. In this way, the rotating shaft can be positioned. This process does not require repeated installation and disassembly of the rotating shaft. The operation is simple, which not only improves the cutting efficiency of the rotating shaft, but also reduces the labor intensity of the workers. 2. By setting a locking unit, when one end of the wing shaft contacts the stop plate, the wing shaft is pushed further. At this time, the stop plate will move towards the movable frame, so that the stop plate is locked into the limit groove. The solenoid valve will then be energized and closed. During this process, the locking pin is locked into the locking hole, thereby positioning the pin and preventing the wing shaft from moving. This also ensures precise control of the cutting length and improves the stability of the wing shaft. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.
[0020] Please see Figures 1 to 8In this embodiment of the invention, a positioning and guiding device for cutting the wing shaft of a drone includes a mounting base 1, a positioning frame 2 mounted on the top of the mounting base 1, a cutter 3 mounted on the top of the positioning frame 2, a positioning ring 9 mounted on the inner side of the positioning frame 2 above the mounting base 1, a limiting connector mounted on the inner side of the positioning ring 9, a controller 8 mounted on one side of the positioning frame 2, a limiting sleeve 7 mounted on one end of the positioning frame 2, a movable frame 5 penetrating the positioning frame 2 inserted into the inner side of the limiting sleeve 7, a locking unit connected to the limiting connector mounted on one side of the movable frame 5, a connecting ring 10 mounted on one end of the movable frame 5, a first lead screw 11 rotatably connected to one side of the positioning frame 2 via a bearing, the outer wall of the connecting ring 10 movably sleeved on the first lead screw 11, and rulers 6 mounted on both sides of the movable frame 5. The limiting connector includes a movable insert 16 that is inserted into the positioning ring 9. The movable insert 16 extends from the outside of the positioning ring 9 to the inside of the positioning ring 9. The end of the movable insert 16 away from the center of the positioning ring 9 is rotatably connected to a slanted pressure frame 14 via a rotating shaft. The end of the slanted pressure frame 14 is rotatably connected to a movable ring 18 via a rotating shaft. The movable ring 18 is located at one end of the positioning ring 9. A second lead screw 17 that passes through the movable ring 18 is provided at one end of the positioning ring 9. A U-shaped splicing block 19 is installed at the end of the movable insert 16 near the center of the positioning ring 9. The inner side of the U-shaped splicing block 19 is rotatably connected to a guide roller 20 via a rotating shaft.
[0021] There are two guide rollers 20, and the two guide rollers 20 are symmetrically arranged along the vertical central axis of the U-shaped splicing block 19. There are multiple movable inserts 16, and the multiple movable inserts 16 are distributed at equal distances along the center of the positioning ring 9. The centers of the positioning ring 9, the movable ring 18, and the connecting ring 10 are coaxial.
[0022] In this embodiment, the first lead screw 11 is rotated first, and the movable frame 5 moves relative to the limiting sleeve 7 by the movement of the connecting ring 10 along the first lead screw 11. During this process, the lateral distance between one side of the movable frame 5 and the cutting blade on the cutter 3 is determined by the position of the limiting sleeve 7 corresponding to the scale line of the ruler 6. Then, the rotating shaft to be cut is passed through the connecting ring 10, the movable ring 18, and the positioning ring 9. Subsequently, the second lead screw 17 is rotated, and the rotation of the second lead screw 17 causes the movable ring 18 to move relative to the positioning ring 9, thereby causing the inclined pressure frame 14 to drive the movable insert 16 to move. The movement of the movable insert 16 adjusts the distance from the center of the guide clamp roller 20 to the center of the positioning ring 9, thereby bringing the guide clamp roller 20 into contact with the rotating shaft to be cut. Then, the rotating shaft is pushed further. The rotating shaft is brought into contact with the side of the movable frame 5 away from the connecting ring 10. At this time, the locking unit operates to lock the guide roller 20, preventing the guide roller 20 from rotating relative to the U-shaped splicing block 19. This positions the rotating shaft. Then, the rotating shaft is cut by the operation of the cutter 3. After the cutting is completed, the locking unit is operated to release the guide roller 20. Then, the rotating shaft is pushed to make the cut end of the rotating shaft fit against the side of the movable frame 5 again. At this time, the locking unit will lock the guide roller 20 again. This process is repeated to achieve continuous cutting of the rotating shaft. During this process, there is no need to repeatedly install and disassemble the rotating shaft. The operation is simple, which not only improves the cutting efficiency of the rotating shaft, but also reduces the labor intensity of the workers.
[0023] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 , Figure 4 The limiting connector also includes a piston cylinder 22 installed on the outer wall of the positioning ring 9 and located on one side of the movable insert block 16. A piston rod 23 extending to the outside of the piston cylinder 22 is inserted inside the piston cylinder 22. A solenoid valve 21 is connected to one side of the bottom of the piston cylinder 22. A disc 24 is installed at one end of the guide roller 20. A shift pin 25 is connected to one end of the disc 24. A positioning slide rail 26 is sleeved on the outside of the shift pin 25. A U-shaped frame 15 penetrating the positioning ring 9 is provided on the outside of the positioning slide rail 26. One end of the piston rod 23 is fixedly connected to the U-shaped frame 15.
[0024] The diameter of the shift pin 25 is equal to the width of the inner wall of the positioning slide rail 26, the center of the disc 24 is coaxial with the center of the guide roller 20, and the center of the disc 24 is misaligned with the center of the shift pin 25.
[0025] In this embodiment, when the movable insert 16 moves relative to the positioning ring 9, the guide roller 20 drives the positioning slide rail 26 to move via the disc 24 and the shift pin 25, thereby making the U-shaped frame 15 and the movable insert 16 move synchronously. During this process, the piston rod 23 moves relative to the piston cylinder 22. When pushing the wing pivot, the guide roller 20 comes into contact with the wing pivot, and at this time, the guide roller 20 will rotate relative to the U-shaped splicing block 19. At this time, the disc 24 will drive the positioning slide rail 26 to move upward via the shift pin 25. As the piston rod moves up and down, the U-shaped frame 15 will drive the piston rod 23 to move, so that the piston rod 23 moves up and down relative to the piston cylinder 22. This allows outside air to be drawn into the piston cylinder 22 through the solenoid valve 21 or the air in the piston cylinder 22 to be discharged through the solenoid valve 21. When the solenoid valve 21 is energized and closed, the air inside the piston cylinder 22 and below the piston rod 23 will lose its flow space. Thus, the piston rod 23 cannot move relative to the piston cylinder 22, thereby limiting and locking the guide roller 20.
[0026] Please refer to this carefully. Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 7 The locking unit includes a connecting compartment 4 installed at the end of the movable frame 5 away from the connecting ring 10. A pin 32 extending to the inside of the movable frame 5 is inserted into the connecting compartment 4. A limiting groove 28 located outside the pin 32 is opened on the inside of the movable frame 5. A stop plate 27 is installed at one end of the pin 32. The other end of the pin 32 is installed on a second contact piece 30 located inside the connecting compartment 4. A first contact piece 29 located on one side of the second contact piece 30 is installed on the inner wall of the connecting compartment 4. A locking hole 33 is opened on the pin 32. A second telescopic spring 31 connected to the inner wall of the connecting compartment 4 is provided on one side of the locking hole 33. A locking pin 12 extending to the inside of the connecting compartment 4 is inserted into the outer wall of the connecting compartment 4. A first telescopic spring 13 connected to the locking pin 12 is provided on the outer wall of the connecting compartment 4.
[0027] The first contact 29 is electrically connected to the solenoid valve 21 via a wire, the second contact 30 is electrically connected to an external power supply via a wire, the depth of the limiting groove 28 is equal to the thickness of the resisting plate 27, the bottom end of the locking pin 12 is provided with a ball, and the diameter of the locking hole 33 is equal to the bottom diameter of the locking pin 12.
[0028] In this embodiment, when one end of the wing shaft contacts the stop plate 27, the wing shaft is pushed further. At this time, the stop plate 27 moves towards the movable frame 5, thereby engaging the stop plate 27 into the limiting groove 28. Simultaneously, the first contact piece 29 aligns with the second contact piece 30, and the solenoid valve 21 is energized and closed. During this process, the locking hole 33 moves to the position aligned with the locking pin 12. At this time, the locking pin 12 engages into the locking hole 33 under the elastic restoring force of the first telescopic spring 13. This is done to position the pin 32. After the wing shaft is cut once, the part of the wing shaft that is attached to the stop plate 27 will fall off. At this time, the locking pin 12 is pulled to separate the locking pin 12 from the locking hole 33. Then the pin 32 will be restored under the elastic restoring force of the second telescopic spring 31, and then the stop plate 27 can be restored. In this way, the wing shaft can be pushed again, thereby realizing multiple fixed-length cuts of the wing shaft without the need for repeated installation and disassembly of the wing shaft.
[0029] The working principle of this invention is as follows: First, the first lead screw 11 is rotated, and the movable frame 5 moves relative to the limiting sleeve 7 by the movement of the connecting ring 10 along the first lead screw 11. During this process, the lateral distance between one side of the movable frame 5 and the cutting blade on the cutter 3 is determined by the position of the limiting sleeve 7 corresponding to the scale line of the ruler 6. Then, the rotating shaft to be cut is passed through the connecting ring 10, the movable ring 18, and the positioning ring 9. Subsequently, the second lead screw 17 is rotated, and the movable ring 18 moves relative to the positioning ring 9 by the rotation of the second lead screw 17. This causes the inclined pressure frame 14 to drive the movable insert 16 to move. The movement of the movable insert 16 adjusts the distance from the guide clamp roller 20 to the center of the positioning ring 9, thereby making the guide clamp roller 20 contact the rotating shaft to be cut. Then, the rotating shaft is pushed further, so that one end of the rotating shaft contacts the side of the movable frame 5 away from the connecting ring 10. When one end of the wing rotating shaft contacts the stop plate 27, the process continues. When the wing shaft is pushed, the stop plate 27 moves toward the movable frame 5, so that the stop plate 27 is engaged in the limiting groove 28. At the same time, the first contact piece 29 and the second contact piece 30 are aligned. At this time, the solenoid valve 21 is energized and closed. During this process, the locking hole 33 moves to the position aligned with the locking pin 12. At this time, the locking pin 12 is engaged in the locking hole 33 under the elastic restoring force of the first telescopic spring 13, thereby positioning the pin 32. After the wing shaft is cut once, the part of the wing shaft attached to the stop plate 27 will fall off. At this time, the locking pin 12 is pulled to separate the locking pin 12 from the locking hole 33. Then the pin 32 is restored under the elastic restoring force of the second telescopic spring 31, and then the stop plate 27 can be restored. In this way, the wing shaft can be pushed again, thereby realizing multiple fixed-length cuts of the wing shaft without the need for repeated installation and disassembly of the wing shaft.
