Description

Technical Field

[0001] This invention relates to the field of machining technology, and in particular to a device for precision machining holes at multiple intersection points on wing components. Background Technology

[0002] "Multi-intersection precision drilling" is a key process in high-end manufacturing (especially in the aerospace field, such as wing and fuselage joints). Its core is to achieve "high precision, high consistency and high efficiency" of precision drilling for multiple spatially distributed hole intersections (such as cross holes and non-planar array holes on the connection surfaces of different components).

[0003] The holes in a "multi-intersection" configuration are not distributed on a single plane or in a straight line, but rather are spatial intersections that meet the "component connection requirements." Typical scenarios include: component intersections, such as the connection holes between a wing spars (vertical plane) and a rib (sloping plane) (intersecting holes on two planes); array intersections, such as the "multi-row irregular holes" at the fuselage-wing joint (holes are arranged along a spatial curve, with the hole diameter / angle varying with position); and multi-layer connection intersections, such as the three-layer superimposed connection holes between the skin, stringer, and bulkhead (the holes must penetrate multiple layers and be coaxial).

[0004] Existing multi-intersection precision drilling devices for wing components have significant drawbacks in application: On the one hand, "inaccurate positioning" or "clamping deformation" of wing components can directly lead to hole position deviation. Due to the irregular structure of the wing surface, it is difficult to stably support and place the drilling device during actual drilling operations, which can easily lead to positional deviations in the drilling. At the same time, the tight clamping structure of the wing itself causes incalculable damage. On the other hand, the drilling position of the wing is not a simple planar drilling. It often requires precise drilling in narrow and inclined positions (such as vertical holes on wing spars and inclined holes on wing ribs), and the required drilling device must have the ability to change angles in multiple directions.

[0005] Therefore, a multi-intersection precision machining hole-making device is needed for wing components. Summary of the Invention

[0006] This invention proposes a multi-intersection precision drilling device for wing components, which solves the problem in the prior art where "inaccurate positioning" or "clamping deformation" of wing components directly leads to hole position deviation. Due to the irregular structure of the wing surface, it is difficult to stably support and place the drilling device during actual drilling operations, which easily leads to positional deviations in the drilling. At the same time, the tight clamping structure of the wing itself causes incalculable damage. On the other hand, the drilling position of the wing is not a simple planar drilling, but often requires precise drilling in narrow and inclined positions (such as vertical holes on wing spars and inclined holes on wing ribs), requiring the drilling device to have the ability to change angles in multiple directions.

Anti-slip strips are equidistantly distributed on the surfaces of the semicircular main slot, the semicircular secondary slot, and the semicircular slot.

[0015] Preferably, the top of the connecting frame is provided with a detachable base frame. A horizontal servo motor is provided on the horizontal side of the base frame, and a vertical servo motor is provided on the vertical side of the base frame.

The driving gear and the driven gear are connected by a power shaft to form a cooperative rotation structure.

[0019] This invention proposes a multi-intersection precision machining hole-making device for wing components. Compared with the prior art, the advantages of this invention are:

[0020] 1. This invention, through the setting of a flexible support mechanism, can effectively fit and fix various parts of the wing. When the flexible support mechanism is placed on the metal surface where holes need to be made, the semi-circular main groove will change its angle under the limiting action of the anti-slip slide bar and the main frame, fitting the metal surface at the optimal angle. At the same time, if it is in an uneven position, the semi-circular secondary groove will change its angle under the limiting action of the limiting main shaft and the main limiting plate, fitting the metal surface at a better angle. The semi-circular secondary groove will also achieve angle change fitting operation within a smaller range through the limiting secondary shaft and the secondary limiting plate, so as to meet the bonding operation of various types of metal surfaces. The anti-slip strips evenly distributed on the surface of the semi-circular main groove, semi-circular secondary groove and semi-circular secondary groove can achieve all-round anti-slip operation on the metal surface, ensuring the stability of the device itself.

[0021] 2. This invention enables multi-directional angle transformation of the alloy drill bit by setting a transverse limiting arc groove and a longitudinal limiting arc groove. When the transverse servo motor and the longitudinal servo motor operate according to actual needs, they will drive the transverse limiting arc groove and the longitudinal limiting arc groove to rotate. The intersection of the transverse limiting arc groove and the longitudinal limiting arc groove always forms a rectangular frame, which can control the angle of the power shaft and its auxiliary components, thereby indirectly completing the angle transformation of the alloy drill bit.

[0022] 3. This invention, by setting a cross-shaped arc groove and a concave sphere, can provide stable output power while cooperating with the multi-directional angle transformation of the alloy drill bit; since the power shaft moves within the rectangular frame formed by the intersection of the transverse and longitudinal limiting arc grooves, it will drive the auxiliary servo motor to perform angle transformation. To ensure stable power output, the cross-shaped arc groove will cooperate with the concave sphere to perform angle rotation operation, ensuring that the radius of power output remains stable while the angle of the power shaft changes.

[0023] 4. This invention, by setting up a drive shaft, a strip tooth, and a transmission gear, enables multi-point drilling operations with alloy drill bits, breaking the limitations of single-plane / linear distribution drilling. The main servo motor drives the drive shaft to rotate. Utilizing the meshing structure between the combined sliding ring and the drive shaft, the connecting plate is adjusted longitudinally. The sliding of the driven shaft provides stable support, preventing recoil force from causing device position shift when the alloy drill bit performs multi-point drilling. Simultaneously, the transmission gear is driven by a servo motor at the bottom of the connecting plate. Utilizing the meshing structure between the transmission gear and the strip tooth, as well as the limiting effect of the sliding rod, the directional drilling mechanism is adjusted laterally.

By utilizing the meshing structure between the combined sliding ring 7 and the drive shaft 3, the connecting plate 8 will be driven to achieve the longitudinal orientation adjustment. The sliding of the driven shaft 6 will provide stable support force and prevent the alloy drill bit 1415 from generating recoil force when drilling at multiple intersections, thus avoiding device position displacement.

By utilizing the meshing structure between the transmission gear 13 and the strip tooth 10 and the limiting effect of the slide rod 12, the lateral hole-making mechanism 14 will be driven to perform lateral adjustment.

[0043] Furthermore, the bottom of the main frame 1 is provided with a resisting slide bar 202. One end of the resisting slide bar 202 is provided with a detachable semi-circular main groove 201. A detachable limiting spindle 203 is provided in the semi-circular main groove 201. A main limiting plate 204 is provided at the center of the limiting spindle 203.

A detachable limiting secondary shaft 207 is provided in the semi-circular secondary groove 206. A secondary limiting plate 208 is provided at the center of the limiting secondary shaft 207. A detachable semi-circular secondary groove 209 is provided in the semi-circular secondary groove 206. When placed on the metal surface to be drilled, the semi-circular main groove 201 will... The anti-slip rod 202 achieves angle change under the limiting action of the main frame 1, and fits the metal surface at the optimal angle. At the same time, if it is in an uneven position, the semi-circular secondary groove 206 achieves angle change under the limiting action of the limiting main shaft 203 and the main limiting plate 204, and fits the metal surface at a better angle. The semi-circular secondary groove 209 will also achieve angle change and fitting operation within a smaller range through the limiting secondary shaft 207 and the secondary limiting plate 208, so as to meet the attachment operation of various types of metal surfaces. The anti-slip strips 205 evenly distributed on the surface of the semi-circular main groove 201, semi-circular secondary groove 206 and semi-circular secondary groove 209 can achieve all-round anti-slip operation on the metal surface, ensuring the stability of the device itself.

[0044] Furthermore, the resisting slide bar 202 is embedded in the arc-shaped slide groove opened on the outside of the semi-circular main groove 201, and the semi-circular secondary groove 206 is in a rotating structure with the main limiting plate 204 through the limiting spindle 203, and the semi-circular secondary groove 206 is in a limiting structure with the main limiting plate 204; the semi-circular main groove 201 will achieve an angle change under the limiting action of the resisting slide bar 202 and the main frame 1, so as to fit the metal surface at the best angle. At the same time, if it is in an uneven position, the semi-circular secondary groove 206 will achieve an angle change under the limiting action of the limiting spindle 203 and the main limiting plate 204, so as to fit the metal surface at a better angle.

[0045] Furthermore, the semicircular slot 209 is rotatably connected to the secondary limiting plate 208 via the limiting sub-shaft 207, and the semicircular slot 209 is also limited by the secondary limiting plate 208. Anti-slip strips 205 are evenly distributed on the surfaces of the semicircular main slot 201, the semicircular secondary slot 206, and the semicircular slot 209. The semicircular slot 209 can achieve angle change and bonding operations within a smaller range through the limiting sub-shaft 207 and the secondary limiting plate 208 to meet the bonding operations of various types of metal surfaces. The anti-slip strips 205 evenly distributed on the surfaces of the semicircular main slot 201, the semicircular secondary slot 206, and the semicircular slot 209 can achieve all-round anti-slip operations on the metal surface, ensuring the stability of the device itself.

[0046] Furthermore, the top of the connecting frame 11 is provided with a detachable base frame 1401. A horizontal servo motor 1402 is provided on the horizontal side of the base frame 1401, and a vertical servo motor 1403 is provided on the vertical side of the base frame 1401. The output end of the horizontal servo motor 1402 is provided with a detachable horizontal limiting arc groove 1404, and the output end of the vertical servo motor 1403 is provided with a detachable vertical limiting arc groove 1405. The top of the base frame 1401 is provided with a support plate 1406, the top of the support plate 1406 is provided with a cross-shaped arc groove 1407, and the top of the cross-shaped arc groove 1407 is provided with a detachable concave sphere 1408. An auxiliary servo motor 1409 is located inside the concave sphere 1408. The output end of the auxiliary servo motor 1409 is provided with a power shaft 1410. The surface of the power shaft 1410 is fitted with a limiting base plate 1411, and the top of the power shaft 1410 is fitted with a limiting top plate 1412. The end of the power shaft 1410 is provided with a drive gear 1413, and the side of the drive gear 1413 is meshed with a driven gear 1414. The top of the power shaft 1410 is provided with an alloy drill bit 1415. The hole making position of the wing is not a simple planar hole making. It is often necessary to make precise holes in narrow and inclined positions (such as vertical holes of wing spars and inclined holes of wing ribs). By using the cooperation of the transverse limiting arc groove 1404 and the longitudinal limiting arc groove 1405, the alloy drill bit 1415 can have multi-directional angle transformation.

[0047] Furthermore, the transverse limiting arc groove 1404 and the longitudinal limiting arc groove 1405 form a cross shape, and the power shaft 1410 passes through the rectangular frame formed by the transverse limiting arc groove 1404 and the longitudinal limiting arc groove 1405. The transverse limiting arc groove 1404 and the longitudinal limiting arc groove 1405 can realize the multi-directional angle transformation of the alloy drill bit 1415. When the transverse servo motor 1402 and the longitudinal servo motor 1403 operate according to actual needs, they will drive the transverse limiting arc groove 1404 and the longitudinal limiting arc groove 1405 to rotate. The intersection of the transverse limiting arc groove 1404 and the longitudinal limiting arc groove 1405 always forms a rectangular frame, which can control the angle of the power shaft 1410 and its auxiliary components, thereby indirectly completing the angle transformation of the alloy drill bit 1415.

[0048] Furthermore, the bottom surface of the concave sphere 1408 is provided with a cross-shaped arc-shaped slide bar, and the concave sphere 1408 and the cross-shaped arc-shaped slide groove 1407 have a sliding structure. Since the power shaft 1410 moves within the rectangular frame formed by the intersection of the transverse limiting arc groove 1404 and the longitudinal limiting arc groove 1405, it will drive the auxiliary servo motor 1409 to change angle. In order to ensure stable power output, the cross-shaped arc-shaped slide groove 1407 will cooperate with the cross-shaped arc-shaped slide bar on the bottom surface of the concave sphere 1408 to perform angle rotation operation, ensuring that while the angle of the power shaft 1410 changes, the radius distance of its power output remains stable.

[0049] Furthermore, the limiting base plate 1411 and the limiting top plate 1412 are respectively located at the bottom of the longitudinal limiting arc groove 1405 and the top of the transverse limiting arc groove 1404. The limiting base plate 1411 and the limiting top plate 1412 are connected by a tie rod to form a limiting structure. The driving gear 1413 and the driven gear 1414 are connected by a power shaft 1410 to form a cooperative rotation structure. The limiting structure formed by the limiting base plate 1411 and the limiting top plate 1412 connected by a tie rod can ensure that the positions of the power shaft 1410, the concave ball 1408 and the auxiliary servo motor 1409 remain stable. Only the angle needs to be changed, and the radius of the power output remains stable. At the same time, the meshing connection structure of the driving gear 1413 and the driven gear 1414 can be used to form a multi-intersection machining hole-making operation.

[0050] Working principle: For precision machining of holes at multiple intersection points on this type of wing component, the following aspects can be considered in practice;

[0051] First, when drilling a hole in a certain part of the wing, the device is placed on the metal surface where the hole needs to be drilled. The semi-circular main groove 201 will change its angle under the limiting action of the resisting slide bar 202 and the main frame 1, so as to fit the metal surface at the best angle. At the same time, if it is in an uneven position, the semi-circular secondary groove 206 will change its angle under the limiting action of the limiting main shaft 203 and the main limiting plate 204, so as to fit the metal surface at a better angle. The semi-circular secondary groove 209 will also achieve angle change and fitting operation within a smaller range through the limiting secondary shaft 207 and the secondary limiting plate 208, so as to meet the bonding operation of various types of metal surfaces. The anti-slip strips 205 evenly distributed on the surface of the semi-circular main groove 201, semi-circular secondary groove 206 and semi-circular secondary groove 209 can achieve all-round anti-slip operation on the metal surface, ensuring the stability of the device itself.

[0052] Secondly, the main servo motor 3 drives the drive shaft 5 to rotate. The meshing structure between the combined sliding ring 7 and the drive shaft 3 drives the connecting plate 8 to achieve longitudinal orientation adjustment. The sliding of the driven shaft 6 provides stable support force, preventing the alloy drill bit 1415 from generating recoil force and causing the device to shift position when drilling at multiple intersections. The transmission gear 13 is driven by the servo motor at the bottom of the connecting plate 8. The meshing structure between the transmission gear 13 and the strip tooth 10, as well as the limiting effect of the slide rod 12, drives the directional drilling mechanism 14 to achieve lateral orientation adjustment.

[0053] Next, the hydraulic rod is used to extend the connecting frame 11. The horizontal servo motor 1402 and the vertical servo motor 1403 operate according to actual needs, which will drive the horizontal limiting arc groove 1404 and the vertical limiting arc groove 1405 to rotate. The intersection of the horizontal limiting arc groove 1404 and the vertical limiting arc groove 1405 always forms a rectangular frame, which can control the angle of the power shaft 1410 and its auxiliary components, thereby indirectly completing the angle change of the alloy drill bit 1415.

[0054] Then, as the power shaft 1410 moves within the rectangular frame formed by the intersection of the transverse limiting arc groove 1404 and the longitudinal limiting arc groove 1405, it will drive the auxiliary servo motor 1409 to change angle. To ensure stable power output, the cross-shaped arc groove 1407 will cooperate with the concave sphere 1408, which has a cross-shaped arc slide bar on its bottom surface, to perform angle rotation operation, ensuring that while the angle of the power shaft 1410 changes, the radius distance of its power output remains stable.

[0055] Finally, by utilizing the meshing connection structure between the driving gear 1413 and the driven gear 1414, a multi-intersection machining hole-making operation can be formed.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
