[0002] Aviation metal tubing is mainly made of different materials such as steel, aluminum, and titanium, and requires multiple cuts during the processing of metal tubing. The traditional process for cutting aviation metal tubing is to use a high-speed steel saw blade cutting machine or a band saw for sawing. After sawing, the operator uses a file to trim and deburr the cut surface.

[0003] The above operating method has the following drawbacks: it involves high labor intensity, and it is difficult to guarantee the surface quality, flatness, and perpendicularity of the cut surface. Utility Model Content

[0004] The purpose of this utility model is to provide a precision cutting tool and tool mechanism for cutting the cross-section of aerospace metal pipes, in order to solve the problems in the background art.

[0005] To achieve the above objectives, the following technical solution is adopted: a precision cutting tool for cutting the cross-section of aerospace metal pipes, including a tool holder;

[0006] Several blades are detachably connected to the blade holder via a connecting assembly;

[0007] Several blades are arranged along the radial direction of the tool holder, and several blades can rotate in the same plane of rotation.

[0008] Preferably, the connecting assembly includes a plurality of disassembly grooves disposed on the outer peripheral wall of the tool holder, a plurality of mounting grooves disposed on the end face of the tool holder that cooperate with the cutting blade, a threaded hole disposed on the disassembly grooves and communicating with the mounting grooves, and a plurality of fasteners connected to the threaded hole, wherein the fasteners are bolts or screws.

[0009] Preferably, each of the mounting slots has a chip removal groove.

[0010] This utility model also proposes a cutting tool mechanism, including the above-mentioned cutting tool;

[0011] The blade is attached to the end of the blade holder furthest from the blade.

[0012] The handle is attached to the end of the blade furthest from the base;

[0013] The pull stud is attached to the other end of the handle.

[0014] Preferably, the handle has a tapered structure.

[0015] Preferably, the tool holder is connected to the tool body by bolts.

[0016] The beneficial effects achieved by this utility model are:

[0017] This utility model uses a standard tool holder structure mounted on the spindle. The spindle rotates at high speed via a servo, driving the tool mechanism to trim and deburr the cut surface. At the same time, it can precisely control the trimming dimensions, greatly improving the trimming efficiency and quality, effectively ensuring the flatness and perpendicularity of the cut surface, and reducing labor intensity.

[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Please refer to Figure 1 , Figure 2 and Figure 3 A precision cutting tool for cutting the cross-section of aerospace metal pipes, including a tool holder 1;

[0025] Several blades 2 are detachably connected to the blade holder 1 via a connecting assembly;

[0026] Several blades 2 are arranged along the radial direction of the tool holder 1, and several blades 2 can rotate in the same plane of rotation.

[0027] When repairing a metal cross-section with multiple blades, the perpendicularity and flatness of the cross-section are effectively guaranteed. At the same time, it is convenient to adjust or replace different blades according to the cross-section shape and pipeline material, so that the cross-section repair can be in the form of a planar structure or a conical surface.

[0028] Please refer to Figure 1 , Figure 2 and Figure 3 The connecting assembly includes several disassembly grooves 3 on the outer peripheral wall of the tool holder 1, the disassembly grooves 3 being fan-shaped; several mounting grooves 4 on the end face of the tool holder 1 that mate with the blade 2; threaded holes 5 on the disassembly grooves 3 communicating with the mounting grooves 4; and several fasteners connected to the threaded holes 5, the fasteners being bolts or screws. When the blade 2 is mounted on the mounting groove 4, the blade 2 is secured to the mounting groove 4 by connecting the fasteners to the threaded holes 5, thus achieving a detachable connection and facilitating blade replacement according to different materials of aviation pipelines.

[0029] Please refer to Figure 1 and Figure 2 Each of the mounting slots 4 is equipped with a chip removal groove 6. During the cross-section trimming process, the generated debris is discharged through the chip removal groove 6, preventing debris accumulation and cross-section quality problems.

[0030] Please refer to Figure 1 , Figure 2 and Figure 3 This utility model also proposes a cutting tool mechanism, including the cutting tool described above;

[0031] The blade 9 is connected to the end of the blade holder 1 away from the blade 2;

[0033] The pull stud 8 is connected to the other end of the tool holder 7. This facilitates the installation of the tool mechanism on the machine tool spindle. The linear feed rate and speed are controlled by the spindle's servo motor. By adjusting the linear speed and speed, the cross-section finishing requirements of different materials can be met, ensuring finishing efficiency, finishing volume, and finishing quality. This improves operability and installation, avoids scratches caused by using files, and effectively reduces workload.
