[0002] In the field of precision manufacturing, thin-walled parts, especially those with complex shapes such as ⊥-shaped aluminum alloy thin-walled parts, are widely used due to their light weight, high strength, and corrosion resistance.

In addition, during the retention process of thin-walled parts, manual assistance is often required to retain the thin-walled parts. Moreover, the high thermal conductivity of thin-walled parts leads to the heat generated during cutting, which can easily cause deformation of thin-walled parts, seriously restricting production efficiency and product quality.

[0021] In this embodiment, the conveying mechanism 55 includes a machine base 551 installed on the inner ring wall of the rotating ring 53, and a conveyor belt 552 is installed on the machine base 551, and a spacing distance is set between the conveying surface of the conveyor belt 552 and the center of the rotating ring 53; so that when the positioning device 5 completes the positioning of the ⊥-shaped aluminum alloy thin-walled part 3, the ⊥-shaped aluminum alloy thin-walled part 3 and the conveyor belt 552 are separated from each other, so that the vibration generated by the ⊥-shaped aluminum alloy thin-walled part 3 during the cutting process can be better transmitted to the vibration suppression mechanism 6, and the vibration generated by the vibration suppression mechanism 6 can be absorbed, so as to facilitate the vibration suppression function of the vibration suppression mechanism 6, thereby avoiding the cutting chatter generated when cutting the ⊥-shaped aluminum alloy thin-walled part 3, improving the processing quality and cutting efficiency of the ⊥-shaped aluminum alloy thin-walled part 3 and reducing the wear of the tool 24.

[0022] In this embodiment, the positioning mechanism 56 includes a ring frame 561 which is coaxially arranged with the rotating ring 53 and installed at the end of the machine base 551. Three groups of telescopic rods 562 are arranged on the inner wall of the ring frame 561. One group of telescopic rods 562 is used to support the outer surface of the horizontal thin wall of the ⊥-shaped aluminum alloy thin-walled part 3, and the remaining two groups of telescopic rods 562 are respectively used to support the outer surface of the vertical thin wall of the ⊥-shaped aluminum alloy thin-walled part 3, and a positioning block 563 is installed at the output end of the telescopic rod 562. The positioning block 563 is installed with a vibration suppression mechanism 6 for reducing the vibration of the ⊥-shaped aluminum alloy thin-walled part 3; specifically, the positioning process of the ⊥-shaped aluminum alloy thin-walled part 3 is as follows. When the ⊥-shaped aluminum alloy thin-walled part 3 is transported to the position as shown in FIG. Figure 1 As shown, the positioning block 563 is driven by three sets of telescopic rods 562 to position the ⊥-shaped aluminum alloy thin-walled part 3.

At the same time, the vibration received by the conduction disk 61 is transmitted to the shock-absorbing spring 2 63. At this time, the shock-absorbing spring 2 63 and the suspended damping ball 64 cooperate to absorb energy and shock-reduce the vibration received by the conduction disk 61. At the same time, through the telescopic deformation of the shock-absorbing spring 2 63 and the suspended damping ball 64, the amplitude frequency of the system composed of the shock-absorbing spring 1 62, the shock-absorbing spring 2 63 and the damping ball 64 has the effect of irregular fluctuation, which can have a large difference with the inherent amplitude frequency of the ⊥-shaped aluminum alloy thin-walled part 3, thereby avoiding resonance and further improving the vibration suppression effect during the cutting of the ⊥-shaped aluminum alloy thin-walled part 3.

[0024] In this embodiment, a guide slide rod 65 is installed at the bottom of the cylindrical groove cavity 5631, and a sliding hole 641 is provided in the damping ball 64 to slide with the guide slide rod 65, so as to prevent the damping ball 64 from colliding with the groove wall of the cylindrical groove cavity 5631 under the action of centrifugal force.

[0025] In this embodiment, when the outer disk surface of the conducting disk 61 is flush with the outer end surface of the positioning block 563, the shock absorbing spring 1 62 is in a compressed state.

[0026] In this embodiment, the driving mechanism 54 includes a gear ring 541 and a rotating shaft 542, the gear ring 541 is installed on the ring frame 561, the rotating shaft 542 is rotatably installed to penetrate and rotate on the through-hole frame seat 52, a gear 1 543 meshing with the gear ring 541 is installed on the rotating shaft 542, a motor 544 is installed on a group of the through-hole frame seats 52, and a gear 2 545 meshing with the gear 1 543 is installed on the output end of the motor 544; specifically, when it is necessary to cut the ⊥-shaped aluminum alloy thin-walled part 3, the motor 544 is started, the motor 544 drives the gear 2 545 to drive the gear 1 543 to rotate, and the gear 1 543 drives the gear ring 541 to rotate, thereby driving the ⊥-shaped aluminum alloy thin-walled part 3 to rotate.

[0028] In this embodiment, a collection box 4 for collecting the cut ⊥-shaped aluminum alloy thin-walled parts 3 is installed on the machine platform 1 .

[0029] In specific implementation, it includes the following steps:

[0030] Step I: The ⊥-shaped aluminum alloy thin-walled part 3 is introduced into the conveying mechanism 55 and conveyed by the conveying mechanism 55, such as Figure 1 As shown;

[0031] Step II: Start the positioning mechanism 56 to position the ⊥-shaped aluminum alloy thin-walled part 3, so that the center of the cross section of the ⊥-shaped aluminum alloy thin-walled part 3 is adjusted to coincide with the axis of the rotating ring 53, and the ⊥-shaped aluminum alloy thin-walled part 3 and the conveyor belt 552 are separated from each other;

[0032] Step III: starting the driving mechanism 54 to drive the ⊥-shaped aluminum alloy thin-walled part 3 to rotate;

[0033] Step IV: Start the cutting device 2, and the belt transmission mechanism 23 drives the tool 24 to rotate. At the same time, the linear guide rail 21 controls the moving seat 22 to move, so that the tool 24 cuts the ⊥-shaped aluminum alloy thin-walled part 3. In this process, when the tool 24 and the ⊥-shaped aluminum alloy thin-walled part 3 are cut, the vibration generated is absorbed by the vibration suppression mechanism 6. In addition, through the self-rotation of the ⊥-shaped aluminum alloy thin-walled part 3, when the tool 24 cuts the ⊥-shaped aluminum alloy thin-walled part 3, the cutting feed direction of the ⊥-shaped aluminum alloy thin-walled part 3 presents a circular effect and a gradually shrinking circular shape. On the one hand, it can greatly make the cutting amount and friction effect of the ⊥-shaped aluminum alloy thin-walled part 3 more uniform and stable. On the other hand, at the same time, the heat dissipation effect during the cutting process is greatly improved.
