[0029] A pipe revolution cutting device, such as Figure 1 and Figure 2 As shown, including:

[0030] A revolution disk 1, a bearing, a driving ring gear 4, a revolution drive motor 7, and a passive ring gear 5 arranged on the revolution disk 1, wherein the output end of the revolution drive motor 7 is connected to the driving ring gear 4, the driving ring gear 4 is meshed with the passive ring gear 5, and the revolution disk 1 is mounted on the mounting plate 3 through the bearing;

[0031] The cutting tool mechanism 2 and the conductive slip ring 9, the cutting tool mechanism 2 is arranged on the rotating disk 1 and is connected to the power supply through the conductive slip ring 9;

[0032] The first counterweight is disposed on the orbiting disk 1 and is used to increase the moment of inertia of the orbiting disk 1 .

[0033] By setting the passive ring gear 5 on the public rotating disk 1 and configuring a first counterweight block on the public rotating disk 1, the rotational inertia of the public rotating disk 1 can be greatly increased while improving the stability during rotation, thereby reducing the probability of drift of the axis of the public rotating disk 1 under long-term use and improving cutting accuracy.

[0034] In this embodiment, the first counterweight is annular and the axis of the first counterweight coincides with the axis of the rotating disk 1, thereby providing a more uniform increase in the moment of inertia.

[0035] like Figure 3 As shown, the outer edge side of the public rotating disk 1 is provided with an annular groove, and the mounting plate 3 is provided with an annular protrusion that matches the annular groove, and the annular protrusion is embedded in the annular groove and slides relatively. By designing the annular groove and the annular protrusion on the mounting plate 3, the engagement of the two can increase the anti-bias torque, thereby reducing the probability of drift of the axis of the public rotating disk 1.

[0036] Specifically, the outer surface of the annular protrusion and the inner surface of the annular groove are smoothly arranged, and the friction coefficient between the two should be small enough, so as to reduce the generation of friction heat.

[0037] In addition, in this embodiment, a second counterweight is provided on the mounting plate 3, so as to improve the overall stability of the mounting plate 3, and the mounting plate 3 can also be strengthened and fixed to the base support surface by some reinforced legs.

[0038] like Figure 3 As shown, the public rotating disk 1 includes a first disk body and a second disk body, the outer diameter of the first disk body is larger than the second disk body, an annular groove is provided on the first disk body, and the second disk body is connected to the mounting plate 3 through a bearing. The rotating disk adopts a stacking method of two disk bodies, so that the design of the assembly structure can be simplified. Specifically, in this embodiment, the first counterweight block is provided on the first disk body, the cutting tool mechanism 2 is also provided on the first disk body, and the thickness of the first disk body is greater than that of the second disk body.

[0039] In addition, the revolution driving motor 7 is mounted on the mounting plate 3 and is connected to the driving ring gear 4 via a reducer.

[0040] In addition to the first counterweight block and the second counterweight block mentioned above, in this embodiment, three third counterweight blocks 7 are further provided, the mass of the third counterweight block 10 is substantially equal to the mass of the cutting tool mechanism 2, and the mass center positions of the three third counterweight blocks 10 and the mass center positions of the cutting tool mechanism 2 are on the circumference of the same circle. In this way, based on the third counterweight block 10, the problem of the mass center of the rotating disk 1 body deviating from its own axis due to the deadweight of the cutting tool mechanism 2 can be effectively solved.

[0041] In the present application, the working principle of the specific cutting tool mechanism 2 is the same as that in the prior art, and in order to avoid ambiguity in the purpose of the present application, it will not be described in detail.
