Description

A wire and cable processing platform for aerospace applications Technical Field

[0001] This application relates to the field of wire and cable processing technology, and in particular to a wire and cable processing platform for aerospace applications. Background Technology

[0002] To ensure the safety of aerospace engineering, fluoroplastics, which have performance several times higher than ordinary plastics, are generally used to manufacture wires and cables for aerospace applications. As carriers of electricity and energy, the quality of wires and cables determines transmission loss, cost savings, and operational safety.

[0003] In the production of wires and cables, when it is necessary to connect two wires and cables together, it is necessary to weld the two wires and cables together.

[0004] When welding wires and cables, in order to ensure the strength and quality of the connection between the two wires and cables, it is best to fully weld the cables. Therefore, during the welding process, the welder needs to flip the wires and cables. After welding the side facing the welder, the side facing away from the welder is flipped to the side facing the welder and welding continues.

[0005] Currently, the flipping of electrical wires and cables is mostly done manually. This can easily lead to breakage or misalignment of the two wires and cables during the flipping process due to uneven force. This is especially true when welding thick electrical wires and cables, where it's difficult to apply even force to both wires during the flipping process. During welding, incomplete flipping can create welding dead zones, preventing the two wires from being fully welded and thus affecting the weld quality.

[0038] The present application will be further described in detail below with reference to Figures 1-7.

[0039] Example 1

[0040] This application discloses a processing platform for aerospace wires and cables.

[0041] Referring to Figure 1, the aerospace wire and cable processing platform includes a base 1, on which two cable fixing mechanisms 2 are arranged side-by-side at intervals. The cable fixing mechanisms 2 are fixed to the base 1. Both cable fixing mechanisms 2 are used to clamp and fix wires and cables. The space reserved between the two cable fixing mechanisms 2 is the space for the two wires and cables to be joined and the working space for welding.

[0042] Referring to Figures 1, 2, and 3, the cable fixing mechanism 2 has a fixed arm 21 fixed to the upper surface of the base 1, and a flipping arm 22 is provided at the top end of the fixed arm 21. One end of the flipping arm 22 is hinged to the fixed arm 21 via a hinge shaft 221. The hinge shaft 221 and the flipping arm 22 are welded and fixed together. The flipping arm 22 can rotate 180° around the hinge shaft 221. A clamping claw 23 is fixed to the other end of the flipping arm 22, which is used to clamp and fix the wires and cables.

[0043] The clamping claws 23 of the two cable fixing mechanisms 2 are horizontally opposite each other, with a distance between them. When connecting two wires and cables, one clamping claw 23 of the cable fixing mechanism 2 clamps and fixes one wire and cable, while the other clamping claw 23 of the cable fixing mechanism 2 clamps and fixes the other wire and cable, and the ends of the two wires and cables are connected between the two clamping claws 23.

[0044] A flipping drive mechanism 3 is provided between the two cable fixing mechanisms 2. The flipping drive mechanism 3 can simultaneously drive the flipping arms 22 of the two cable fixing mechanisms 2 to flip synchronously. The flipping drive mechanism 3 includes a horizontally arranged drive shaft 31, which is located between the fixing arms 21 of the two cable fixing mechanisms 2. One end of the drive shaft 31 passes through the fixing arm 21, and the other end of the drive shaft 31 passes through the other fixing arm 21. The drive shaft 31 is rotatably connected to both fixing arms 21.

[0045] The drive shaft 31 is parallel to the hinge shaft 221 of the tilting arm 22.

[0046] Drive sprockets 32 are fixed at both ends of the drive shaft 31, and the drive sprockets 32 are fixed on the drive shaft 31. The two drive sprockets 32 are located on opposite sides of the two fixed arms 21.

[0047] The tilting drive mechanism 3 also includes a driven sprocket 33 fixedly connected to the hinge shaft 221 of the tilting arm 22. Each of the two tilting arms 22 has a driven sprocket 33 fixed to its hinge shaft 221, and the two driven sprockets 33 are arranged opposite to the two drive sprockets 32. A chain 34 is arranged between the opposite driven sprockets 33 and drive sprockets 32, and the chain 34 meshes with both the driven sprockets 33 and drive sprockets 32.

[0048] When the drive shaft 31 rotates, it drives the hinge shaft 221 to rotate through the transmission action of the driven sprocket 33, the drive sprocket 32 ​​and the chain 34. When the hinge shaft 221 rotates, it drives the tilting arm 22 to tilt.

[0049] The flipping drive mechanism 3 also includes a drive assembly 35 for rotating the drive shaft 31. The drive assembly 35 includes a first motor 351 fixed on the base 1, with the motor shaft of the first motor 351 perpendicular to the drive shaft 31. A first bevel gear 352 and a second bevel gear 353 meshing between the motor shaft of the first motor 351 and the drive shaft 31 are provided. The first bevel gear 352 is fixed to the motor shaft of the first motor 351, and the second bevel gear 353 is fixed to the drive shaft 31.

[0050] A protective cover 4 is also provided on the base 1 to enclose the first motor 351. The protective cover 4 is fixed to the base 1. A through hole is provided on the side wall of the protective cover 4 for the drive shaft 31 to pass through. By enclosing the first motor 351 inside the protective cover 4, the welding slag generated during the welding process of wires and cables is less likely to enter the first motor 351, thus protecting the first motor 351.

[0051] When welding wires and cables, one of the two wires to be welded together is secured using one of the two cable fixing mechanisms 2, and the other is secured using the other cable fixing mechanism 2, ensuring the ends of the two wires and cables are aligned. After welding the side of the wires and cables facing the welder, the worker controls the flipping arms 22 of the two cable fixing mechanisms 2 via the drive assembly 35 to flip the wires and cables from the side facing away from the welder to the side facing the welder. During the flipping process, the flipping arms 22 of the two cable fixing mechanisms 2 flip simultaneously, and the wires and cables are clamped and fixed by the gripping claws 23, keeping the ends of the two wires and cables relatively fixed. Therefore, it is unlikely that the two wires and cables will separate during the flipping process.

[0052] Referring to Figure 4, a fume extraction mechanism 5 is provided on the base 1 to treat the fumes generated during welding. The fume extraction mechanism 5 includes two fume extraction hoods 51, which are fixed to the base 1. The two fume extraction hoods 51 sandwich two cable fixing mechanisms 2 in the middle. A fume inlet 511 is provided on the side of the fume extraction hood 51 facing the cable fixing mechanism 2. The interior of the fume extraction hood 51 is hollow, and the fume inlet 511 connects the interior of the fume extraction hood 51 to the outside.

[0053] A smoke exhaust duct 52 is fixed on the base 1, and an exhaust fan 53 is installed on the smoke exhaust duct 52. The exhaust fan 53 drives the air inside the smoke exhaust duct 52 to circulate. The air inlet of the smoke exhaust duct 52 is connected to the fume hood 51 through a smoke supply pipe 54. One end of the smoke supply pipe 54 is connected to the inside of the smoke exhaust duct 52, and the other end of the smoke supply pipe 54 is connected to the inside of the fume hood 51. The fumes generated during the welding of wires and cables can be drawn into the inside of the fume hood 51 and discharged along the smoke exhaust duct 52, reducing the concentration of fumes in the welding area and thus reducing the harm of fumes to welding workers.

[0054] Example 2

[0055] This application discloses a processing platform for aerospace wires and cables.

[0056] Referring to Figures 5 and 6, the difference between Embodiment 2 and Embodiment 1 is that a movable platform 6 capable of horizontal movement is provided on the base 1, with the movement direction of the movable platform 6 from the front end to the rear end of the base 1. Two cable fixing mechanisms 2 are fixed to the movable platform 6.

[0057] A translation drive mechanism 7 is provided between the base 1 and the mobile platform 6. The translation drive mechanism 7 is used to drive the mobile platform 6 to move in translation.

[0058] The translation drive mechanism 7 includes two parallel guide rails 71, the length of which extends from the front end to the rear end of the base 1. A slide 72 is provided at the bottom end of the moving platform 6 opposite to the guide rails 71. The slide 72 is fixed to the moving platform 6, and is engaged with the guide rails 71 and can move along the length of the guide rails 71.

[0059] A lead screw 73 is provided between two guide rails 71, and the lead screw 73 is rotatably supported on the upper surface of the base 1. The lead screw 73 is parallel to the two guide rails 71. A lead screw nut 74 is threaded onto the lead screw 73, and the lead screw nut 74 is fixedly connected to the moving platform 6.

[0060] A second motor 75 is installed at one end of the lead screw 73 facing the rear end of the base 1. The motor shaft of the second motor 75 is coaxial with that of the lead screw 73. The motor shaft of the second motor 75 is fixedly connected to the lead screw 73. When the second motor 75 is started, the motor shaft of the second motor 75 drives the lead screw 73 to rotate. The second motor 75 is fixed to the base 1.

[0061] When flipping the wires and cables, the flipping arm 22 will cause the wires and cables to move away from the welding worker. The translation drive mechanism 7 will drive the moving platform 6 to move towards the front end of the base 1, so that the wires and cables away from the welding worker will gradually move closer to the welding worker, making it easier for the welding worker to weld the wires and cables later.

[0062] Example 3

[0063] This application discloses a processing platform for aerospace wires and cables.

[0064] The difference between Example 3 and Example 2 is as follows:

[0065] Referring to Figure 7, a telescopic push-pull device 76 of variable length is provided between the two guide rails 71. The telescopic push-pull device 76 can be a hydraulic cylinder or an electric push rod. The telescopic push-pull device 76 is fixed to the base 1, with one end of the telescopic push-pull device 76 facing the front end of the base 1 and the other end facing the rear end of the base 1. One end of the telescopic push-pull device 76 is fixed to the moving platform 6, and the other end of the telescopic push-pull device 76 is fixed to the base 1.

[0066] When the length of the telescopic push-pull device 76 is extended or shortened, it can push the mobile platform 6 to move.

[0067] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
