Description

Technical Field

[0002] As the core material in the aerospace field, aviation aluminum alloy is widely used in key parts such as fuselage, wings, tail and engine of aircraft and spacecraft with its light weight, high strength, corrosion resistance and easy processing. It is an important support for promoting the development of aerospace technology. For enterprises with limited budget or small production scale, semi-automatic aluminum strip cutting machine has lower cost, so it is usually used to cut aluminum alloy. When cutting, the aluminum strip is first fixed on the machine, and then the cutting machine is started to cut the aluminum strip. However, due to the oxidation of the aluminum alloy surface, a layer of oxide film will be produced. The presence of oxide film will increase the roughness of the cutting surface and reduce the cutting accuracy. At the same time, due to the difference in physical properties between the oxide film and the base material, the cutting surface may be uneven.

DETAILED DESCRIPTION

[0028] 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 described embodiments 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.

[0029] Example 1

[0030] See also Figure 1-Figure 11 , the present invention provides a technical solution:

[0031] An aviation aluminum alloy bar cutting device includes a cutting device body 1 and a processing table 2, and also includes a refining rod 3. The refining rod 3 is located on the processing table 2, and there are multiple refining rods 3. The refining rods 3 are used to remove the oxide film on the position to be cut on the aluminum alloy bar.

[0032] The conveying assembly 4 is arranged on the processing table 2, and the conveying assembly 4 is used to drive the aluminum alloy bar to move on the processing table 2.

[0033] The setting of the conveying component 4 can automatically move the aluminum rod to under the cutter on the cutting device body 1, and can automatically adjust the position of the aluminum rod after cutting is completed. This design reduces the need for manual intervention, making the cutting process of the aluminum rod more continuous and efficient. There is no need to wait for workers to manually place or adjust the aluminum rod, thereby significantly improving the overall production capacity of the production line, and reducing the direct contact between workers and high-speed rotating cutters and heavy machinery parts, thereby reducing the risk of work-related accidents and ensuring production safety. At the same time, it reduces dependence on workers, reduces labor costs, and avoids production delays or quality problems caused by worker fatigue or operational errors.

[0034] The film removing mechanism 8 is arranged on the processing table 2, and the refining rod 3 is arranged on the film removing mechanism 8. The film removing mechanism 8 is used to drive the refining rod 3 to follow the movement of the aluminum rod and synchronously rotate around the aluminum rod to refine and remove the oxide film at the position to be cut on the aluminum rod, so that the cutting tool is in a straight line state when cutting the aluminum rod.

[0035] The advantage of setting up the film removal mechanism 8 is that it can automatically remove the oxide film on the aluminum rod before cutting the aluminum rod. The presence of the oxide film will affect the sharpness and cutting efficiency of the cutting tool, resulting in an uneven cutting surface or burrs. By automatically removing the oxide film, direct contact between the cutting tool and the aluminum rod can be ensured, thereby improving the cutting accuracy and surface quality. Moreover, the oxide film has a high hardness. If cutting is performed directly on the aluminum rod with the oxide film, the wear of the tool will be accelerated. By removing the oxide film in advance, the burden on the tool can be reduced, its service life can be extended, and the frequency and cost of replacing the tool can be reduced. At the same time, the oxide film will increase the friction and resistance during the cutting process, resulting in a more laborious cutting process and increased energy consumption. After removing the oxide film, the cutting process will be smoother, reducing energy consumption and mechanical stress.

[0036] The conveying assembly 4 includes a pushing member 5 arranged on the processing table 2, and the pushing member 5 is used to drive the aluminum rod to move. The pushing member 5 is provided with a driving member 6, and the driving member 6 drives the pushing member 5 to work.

[0038] The setting of the pusher 5 reduces manual intervention in the cutting of the aluminum bars, making the aluminum bar cutting process more continuous and efficient. There is no need to wait for workers to manually place or adjust the aluminum bars, thereby significantly improving the overall production capacity of the production line.

[0040] The synchronizer 7 includes a plurality of rotating plates 71 disposed in the mounting shell 51 , on which a synchronizer ring 72 is rotatably disposed, and on which a plurality of synchronizer slots 73 are formed. The plurality of rotating shafts 65 are each provided with a synchronizer gear 74 engaged with the synchronizer slots 73 .

[0041] The benefit of setting the synchronous member 7 is that it can drive the multiple driving wheels 56 to rotate synchronously, thereby improving the stability of the aluminum rod during movement and further improving the accuracy of aluminum rod cutting.

[0042] During cutting, firstly, the aluminum rod is inserted into the mounting shell 51, and then the motor 1111 is started. The motor 1111 drives the power shaft 114 and the toothed belt wheel 117 to rotate. The toothed belt wheel 117 rotates and drives the toothed belt 118 to rotate, which in turn drives the toothed belt wheel 117 on the rotating shaft 65 to rotate synchronously, and drives the rotating shaft 65 to rotate. The rotating shaft 65 rotates and drives the synchronous gear 74 thereon to rotate. The synchronous gear 74 rotates and drives the synchronous slot 73 engaged therewith to rotate, so that the synchronous ring 72 rotates. Driven by the synchronous slot 73 on 72, multiple synchronous gears 74 rotate synchronously and drive multiple rotating shafts 65 to rotate. When the rotating shaft 65 rotates, the drive shaft 62 is driven to rotate through the driving pulley 66 and the driving belt 67. When the drive shaft 62 rotates, it drives the transmission gear 64 slidably connected thereto to rotate. The rotation of the transmission gear 64 drives the driving gear 61 to be engaged with it to rotate. The rotation of the driving gear 61 drives the rotating shaft 55 to rotate. The rotation of the rotating shaft 55 drives the driving wheel 56 to rotate, thereby pushing the aluminum rod to move toward the cutting tool.

[0045] The advantage of setting up the removal piece 9 is that it can automatically remove the oxide film on the aluminum rod before cutting the aluminum rod. The presence of the oxide film will affect the sharpness and cutting efficiency of the cutting tool, resulting in an uneven cutting surface or burrs. By automatically removing the oxide film, direct contact between the cutting tool and the aluminum rod can be ensured, thereby improving the cutting accuracy and surface quality.

[0046] The rotating member 10 is provided with a rotating groove 101 on the moving ring 94, and the rotating ring 95 is provided with a plurality of rotating teeth 102, and the rotating teeth 102 are rotatably connected with the rotating groove 101, and a through groove 103 is provided on the rotating groove 101, and a positioning plate 104 is provided on the moving ring 94, and a steering shaft 105 is rotatably provided on the positioning plate 104, and a steering gear 106 is provided on the steering shaft 105, and the steering gear 106 One side passes through the through slot 103 and engages with the rotating latch tooth 102, a steering gear 2 107 is provided at one end of the steering shaft 105, a steering shaft 2 108 is rotatably provided on the movable ring 94, a linkage gear 109 engaged with the steering gear 2 107 is provided on the steering shaft 2 108, a linkage gear 2 1010 is provided on the steering shaft 2 108, and a rotating rack 1011 engaged with the linkage gear 2 1010 is provided in the refining chamber 91.

[0047] The benefit of setting the rotating member 10 is that it can drive the refining rod 3 to rotate around the aluminum rod, thereby improving the effect of the refining rod 3 on removing the oxide film on the aluminum rod, ensuring direct contact between the cutting tool and the aluminum rod, thereby improving the cutting accuracy and surface quality.

[0048] The power member 11 includes a power gear 111 disposed on the moving screw 92, a power shaft 112 is rotatably disposed on the refining chamber 91, a power gear 113 engaged with the power gear 111 is disposed on the power shaft 112, a power shaft 114 is rotatably disposed on the outer side of the refining chamber 91, a power pulley 115 is disposed on the power shaft 112 and the power shaft 114, a power belt 116 is disposed on the power pulley 115, and a plurality of the rotating shafts 65 are located in the mounting shell 5.

[0049] When the power shaft 2 114 rotates, the power shaft 112 is driven to rotate through the power pulley 115 and the power belt 116. The rotation of the power shaft 112 drives the power gear 2 113 to rotate. The rotation of the power gear 2 113 drives the power gear 1 111 to rotate. The rotation of the power gear 1 111 drives the moving screw rod 92 to rotate. The rotation of the moving screw rod 92 drives the moving ring 94 threadedly connected to it to move.

[0050] When the moving ring 94 moves, it drives the linkage gear 2 1010 to move synchronously. During the movement of the linkage gear 2 1010, it engages with the rotating rack 1011 and rotates under the push of the rotating rack 1011. The linkage gear 2 1010 rotates, driving the steering shaft 2 108 to rotate. The steering shaft 2 108 rotates to drive the linkage gear 1 109 to rotate. The linkage gear 1 109 rotates to drive the steering gear 2 107 engaged therewith to rotate. The steering gear 2 107 rotates to drive the steering shaft 1 105 to rotate. The steering shaft 105 rotates to drive the steering gear 1 106 to rotate. The steering gear 106 rotates to drive the rotating tooth 102 to move, and then drives the rotating ring 95 connected to the rotating tooth 102 to rotate. The rotation of the rotating ring 95 drives the multi-stage telescopic rod 96 and the refining rod 3 to rotate, and the aluminum rod in the process of moving is refined to remove the oxide film. When the oxide film of the aluminum rod is removed, it moves to the bottom of the cutting tool for cutting. At this time, the motor 1111 rotates in the reverse direction to drive the moving ring 94 to reset. At the same time, because the toothed belt wheel 117 is connected to the rotating shaft 65 through a one-way bearing, the motor 1111 will not drive the aluminum rod to move in the reverse direction when it rotates in the reverse direction.

[0051] At the same time, the arrangement of the extrusion spring 97 can play a buffering role, thereby preventing the surface of the aluminum rod from being damaged due to excessive extrusion force between the refining rod 3 and the aluminum rod.

[0052] When in use, first extend the aluminum rod into the mounting shell 51, then start the motor 1111, the motor 1111 works to drive the power shaft 114 and the toothed belt wheel 117 to rotate, the toothed belt wheel 117 rotates to drive the toothed belt 118 to rotate, and the toothed belt wheel 117 on the rotating shaft 65 rotates synchronously, and drives the rotating shaft 65 to rotate, the rotating shaft 65 rotates to drive the synchronous gear 74 on it to rotate, the synchronous gear 74 rotates to drive the synchronous slot 73 engaged with it to rotate, so that the synchronous ring 72 rotates, and the synchronous ring 72 on the synchronous ring 65 rotates. Driven by the synchronous slot 73 on 72, multiple synchronous gears 74 rotate synchronously and drive multiple rotating shafts 65 to rotate. When the rotating shaft 65 rotates, the drive shaft 62 is driven to rotate through the driving pulley 66 and the driving belt 67. When the drive shaft 62 rotates, it drives the transmission gear 64 slidably connected thereto to rotate. The rotation of the transmission gear 64 drives the driving gear 61 to be engaged with it to rotate. The rotation of the driving gear 61 drives the rotating shaft 55 to rotate. The rotation of the rotating shaft 55 drives the driving wheel 56 to rotate, thereby pushing the aluminum rod to move toward the cutting tool.

[0053] When the power shaft 2 114 rotates, the power shaft 112 is driven to rotate through the power pulley 115 and the power belt 116. The rotation of the power shaft 112 drives the power gear 2 113 to rotate. The rotation of the power gear 2 113 drives the power gear 1 111 to rotate. The rotation of the power gear 1 111 drives the moving screw rod 92 to rotate. The rotation of the moving screw rod 92 drives the moving ring 94 threadedly connected to it to move.

[0054] When the moving ring 94 moves, it drives the linkage gear 2 1010 to move synchronously. During the movement of the linkage gear 2 1010, it engages with the rotating rack 1011 and rotates under the push of the rotating rack 1011. The linkage gear 2 1010 rotates, driving the steering shaft 2 108 to rotate. The steering shaft 2 108 rotates to drive the linkage gear 1 109 to rotate. The linkage gear 1 109 rotates to drive the steering gear 2 107 engaged therewith to rotate. The steering gear 2 107 rotates to drive the steering shaft 1 105 to rotate. The steering shaft 105 rotates to drive the steering gear 1 106 to rotate. The steering gear 106 rotates to drive the rotating tooth 102 to move, and then drives the rotating ring 95 connected to the rotating tooth 102 to rotate. The rotation of the rotating ring 95 drives the multi-stage telescopic rod 96 and the refining rod 3 to rotate, and the aluminum rod in the process of moving is refined to remove the oxide film. When the oxide film of the aluminum rod is removed, it moves to the bottom of the cutting tool for cutting. At this time, the motor 1111 rotates in the reverse direction to drive the moving ring 94 to reset. At the same time, because the toothed belt wheel 117 is connected to the rotating shaft 65 through a one-way bearing, the motor 1111 will not drive the aluminum rod to move in the reverse direction when it rotates in the reverse direction.

[0057] Different from the first embodiment, the pushing wheel 56 is made of rubber. The advantage of setting the pushing wheel 56 of rubber is that it can improve the friction between the pushing wheel 56 and the aluminum rod, and at the same time can prevent the surface of the aluminum rod from being damaged by excessive pressure.
