[0020] The design of the beam part includes a rotating beam 1 and a counterweight beam 2. One end of the rotating beam 1 is connected to the milling cutter device, and the other end is connected to the counterweight beam 2. The bottom beam 100 of the rotating beam 1 is provided with an adjustment strip hole 101.

[0021] The design of the rotating part includes a rotating platform 3, a rotating shaft 4, a sleeve 5, a support leg connection frame 6 and a driving gear ring 7. The rotating shaft 4 is installed on the lower end surface of the rotating platform 3. The sleeve 5 is sleeved on the outside of the rotating shaft 4 through a double-row tapered bearing 8. The rear end surface of the sleeve 5 is connected to the rotating platform 3, and an end cover 10 is installed on the front end surface. The sleeve 5 and the end cover 8 are sealed at the contact between the rotating shaft 4 and the sleeve 5. The support leg connection frame 6 is welded outside the sleeve 5. The driving gear ring 7 is installed on the sleeve 5, which is located between the support leg connection frame 6 and the rotating platform 3. Between the lower end surfaces, an annular groove 900 is arranged on the lower end surface of the rotating platform 3 with the rotating shaft 4 as the center, and the supporting leg connecting frame 6 is installed with an annular slide rail 901 matched with the annular groove 900. The annular groove 900 and the annular slide rail 901 cooperate to form an annular sliding mechanism 9 for assisting the rotation of the rotating platform 3 on the supporting leg connecting frame 6. At least two groups of locking blocks 11 are arranged on the upper end surface of the rotating platform 3. In this example, three groups of locking blocks 11 are arranged along the length direction of the rotating beam 1 to form a limiting groove adapted to the bottom beam 100 of the rotating beam 1.

[0022] In this new type of assembly, the bottom beam 100 of the rotating beam 1 is installed in the limit groove formed by the locking block 11 on the upper end surface of the rotating platform 3, and then the bottom beam 100 of the rotating beam 1 is fixed on the rotating platform 3 by using a plurality of transition support blocks 12, and the cross section of the transition support block 12 is T-shaped. The specific operation is as follows:

[0023] The connection length of the rotating beam 1 and the counterweight beam 2 is determined according to the inner diameter of the annular plane object processed on site, that is, the positions of setting a plurality of transition support blocks 12 in the adjusting strip hole 101 are determined. After the installation position of the transition support block 12 is determined, the transition support block 12 is inserted into the adjusting strip hole 101 to press the bottom beam 100 of the rotating beam 1 and fix it to the rotating platform 3 through the adjusting bolts 13. The counterweight beam 2 is installed on the plurality of transition support blocks 12 through the fixing bolts 14 and is combined with the rotating beam 1 to form a beam portion.

[0024] The application of this example is Figure 5 As shown, during assembly, the support leg connecting frame 6 of the rotating part is installed on the support leg 15 supported on the end surface diameter of the processing object, and the milling cutter device 16 is installed at the end of the rotating beam 1 of the beam part.
