Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a hole-making auxiliary device for a UAV curved surface stacked structure. Background Technology

[0002] A type of curved, laminated structure component in drone parts, such as Figure 6 As shown, the part is a curved laminated structure used for the aerodynamic shape of an aircraft. After the workpiece connector 16 is installed, the outer side of the overall structure is a curved countersunk surface, and the inner side is a nut surface. After the workpiece connector 16 is installed, it is necessary to ensure that the gap between the nut and the inner surface is uniform, the countersunk socket is perpendicular to the hole axis, and the gap between the countersunk side of the bolt and the countersunk socket is uniform, so that the curved laminated structure is subjected to uniform stress and has good connection quality.

[0003] The drilling process for curved laminated structures typically involves first drilling a preliminary hole on the inner nut surface, followed by enlarging the hole on the outer countersunk surface. However, due to the structure of the countersunk surface, fixing the workpiece during drilling is difficult, leading to positioning difficulties and making it hard to apply force to the drill bit. Consequently, it is challenging to control the perpendicularity of the hole axis. When the axis of the preliminary hole deviates during drilling, it is difficult to correct the deviation during subsequent enlarging on the countersunk surface, resulting in uncontrollable perpendicularity of the hole. Ultimately, the perpendicularity of the final hole exceeds the tolerance, and the installation of the workpiece connector 16 on the part is unqualified. To address this issue, a drilling auxiliary device for curved laminated structures in UAVs is proposed. Utility Model Content

[0028] By setting up a positioning component and an auxiliary component in cooperation, the positioning of the hole can be assisted and the accuracy of the hole enlargement can be improved. The positioning component includes a support base 3, a threaded rod 12 and a frustum 13. The top of the base 1 is provided with a first slide groove 2. The support base 3 is fixedly connected to the bottom of the first slide groove 2. The top of the support base 3 is provided with a threaded hole 11. One end of the threaded rod 12 is threadedly connected to the inside of the threaded hole 11. The frustum 13 is threadedly connected to the outside of the threaded rod 12. The top of the frustum 13 is fixedly connected with a turntable 14. The turntable 14 is movably sleeved on the outside of the threaded rod 12. A workpiece 15 is installed on the base 1. A fixing hole 17 is provided on the workpiece 15. The threaded rod 12 passes through the inside of the fixing hole 17. By passing one end of the threaded rod 12 through the inside of the positioning hole 10 and inserting it into the inside of the fixing hole 17 and simultaneously screwing it into the inside of the threaded hole 11, the frustum 13 can be connected to the outside of the threaded rod 12. By rotating the turntable 14, the frustum 13 can be rotated and moved on the outside of the threaded rod 12.

[0029] The auxiliary components include an L-shaped bracket 8 and two fixing bolts 9. The base 1 has second sliding grooves 7 at both ends. The L-shaped bracket 8 is slidably connected to the inside of the second sliding grooves 7. The two fixing bolts 9 are threaded to both sides of the L-shaped bracket 8 and abut against the bottom of the second sliding grooves 7. A positioning hole 10 is provided on the top side of the L-shaped bracket 8. A frustum 13 matches the positioning hole 10, with one end of the frustum 13 inserted into the positioning hole 10. The frustum 13 is rotated by a rotating turntable 14, causing the bottom of the frustum 13 to... The end moves into the interior of the positioning hole 10, thereby pushing the L-shaped bracket 8 to move inside the second slide groove 7 to correct the position of the positioning hole 10. When the L-shaped bracket 8 cannot move, the fixing bolt 9 is rotated so that one end abuts against the bottom of the second slide groove 7, thereby completing the fixing of the L-shaped bracket 8. This ensures that the center lines of the positioning hole 10 and the fixing hole 17 are on the same straight line. Then, the threaded rod 12 and the frustum 13 are disassembled, and the top of the fixing hole 17 can be enlarged through the positioning hole 10.

[0030] To enable the fixing of workpieces 15 with different sized fixing holes 17 and improve the versatility of the device, a first sliding groove 2 is provided on the top of the base 1. A lead screw 4 is rotatably connected to both ends of the first sliding groove 2. The lead screw 4 movably passes through one side of the support base 3. Two limiting blocks 5 are slidably connected inside the first sliding groove 2. The two limiting blocks 5 are movably sleeved on the outside of the lead screw 4. One end of the lead screw 4 extends to one end of the base 1. A hexagonal hole 6 is provided at one end of the lead screw 4. The outside of the lead screw 4 is provided with opposite threaded sections. The two limiting blocks 5 are both threadedly connected to the outside of the lead screw 4. The two limiting blocks 5 abut against the inside of the fixing hole 17. By placing the workpiece 15 on the base 1, with the two limiting blocks 5 inside the fixing hole 17, and then inserting a tool into the hexagonal hole 6, the lead screw 4 is rotated by rotating the tool. The lead screw 4 drives the two limiting blocks 5 to move in opposite directions, so that the two limiting blocks 5 abut against the inside of the fixing hole 17, thus completing the fixing of the workpiece 15.

[0031] The working principle or structural principle is as follows: When positioning and enlarging the workpiece 15, the workpiece 15 is placed on the base 1, and the two limiting blocks 5 are located inside the fixing hole 17. Then, a tool is inserted into the hexagonal hole 6. By rotating the tool, the lead screw 4 is rotated. The lead screw 4 drives the two limiting blocks 5 to move in opposite directions, so that the two limiting blocks 5 abut against the inside of the fixing hole 17, thus completing the fixing of the workpiece 15. Moreover, it can fix workpieces 15 with fixing holes 17 of different sizes, improving the versatility of the device.

[0032] During positioning, one end of the L-shaped bracket 8 is moved into the interior of the second slide groove 7. Then, one end of the threaded rod 12 is passed through the interior of the positioning hole 10 and inserted into the interior of the fixing hole 17, while simultaneously screwed into the interior of the threaded hole 11. At this point, the frustum 13 can be connected to the outside of the threaded rod 12. By rotating the turntable 14, the frustum 13 is rotated, causing the bottom end of the frustum 13 to move into the interior of the positioning hole 10, thereby pushing the L-shaped bracket 8 to move inside the second slide groove 7 to correct the position of the positioning hole 10. When the L-shaped bracket 8 cannot move, the fixing bolt 9 is rotated so that one end abuts against the bottom of the second slide groove 7, thereby completing the fixation of the L-shaped bracket 8. This ensures that the center lines of the positioning hole 10 and the fixing hole 17 are on the same straight line. Then, the threaded rod 12 and the frustum 13 are disassembled, and the positioning hole 10 can be used to assist in the enlargement of the top of the fixing hole 17, improving the accuracy of the enlargement.
