When the outer surface of the ship stern 100 is in contact with each support inclined surface 1511, it means that the fixed frame 11 is advanced in place. Then, multiple groups of radial telescopic assemblies 152 cooperate to clamp the ship stern 100 together, so that the fixed frame 11 and the ship stern 100 are fixedly connected.

[0045] Referring to Figure 13 , each group of radial telescopic assemblies 152 includes a mounting shell 1521, an adjustment screw 1522 and a clamping block 1523.

[0052] Optionally, the fixed seat 21 and the fixed frame 11 can adopt two fixing methods: automatic fixing and manual fixing. In some embodiments where the fixed seat 21 and the fixed frame 11 adopt the automatic fixing method, one or more hydraulic cylinders are installed on the fixed frame 11, and the hydraulic cylinders are used to press the periphery of the fixed disk body 212 against the end face of the fixed frame 11.

[0054] In some embodiments, the stern of the ship 100 has an inner hole surface 140 that needs to be processed.

During the processing, the above-mentioned rotation center line coincides with the axis of the inner hole surface 140, so that the inner surface cutting mechanism 23 can be driven to make circular motion around the axis of the inner hole surface 140 through the first rotation drive component 221, the inner surface cutting mechanism 23 can be driven to make axial motion along the inner hole surface 140 through the first axial drive component 222, and the inner surface cutting mechanism 23 can be driven to make radial motion along the inner hole surface 140 through the first radial drive component 223, so that the inner surface cutting mechanism 23 completes the cutting processing of the inner hole surface 140 when the stern 100 of the ship is stationary.

[0055] Continue to refer to Figure 18 , the first rotation driving assembly 221 includes a first rotation driving source 2211, a driving gear, a first driven gear 2212 and a first rotation main shaft 2213, wherein: the body of the first rotation driving source 2211 is connected to the fixed seat 21; the driving gear is in transmission connection with the power output end of the first rotation driving source 2211; the first driven gear 2212 is meshed with the driving gear and coaxially fixed to one end of the first rotation main shaft 2213; the end of the first rotation main shaft 2213 away from the first driven gear 2212 is connected to the inner surface cutting mechanism 23. In the above structure, the first rotation driving source 2211 drives the first rotation main shaft 2213 to rotate around its own axis (i.e., the above rotation center line) through the driving gear and the first driven gear 2212. The first rotation driving source 2211 can be a motor, and the output shaft of the first rotation driving source 2211 can be connected to the driving gear through a reducer.

At the same time, the axial feed seat 2222 can drive the first rotating spindle 2213 and the inner surface cutting mechanism 23 to move simultaneously along the first direction relative to the fixed seat 21.

[0058] In some embodiments, the body of the third axial drive source 2221 is mounted on the axial feed seat 2222 and its power output end is transmission-connected with the fixed seat 21. In this way, the third axial drive source 2221 and the axial feed seat 2222 move in the first direction relative to the fixed seat 21 at the same time. In other embodiments, it can also be arranged that the body of the third axial drive source 2221 is mounted on the fixed seat 21 and its power output end is transmission-connected with the axial feed seat 2222. In this way, during the movement of the axial feed seat 2222 relative to the fixed seat 21 in the first direction, the third axial drive source 2221 will not move relative to the fixed seat 21. Both of the above-mentioned two connection methods can realize the movement of the axial feed seat 2222 relative to the fixed seat 21 in the first direction, and the axial feed seat 2222 drives the inner surface cutting mechanism 23 to move synchronously while moving in the first direction.

The axial feed seat 2222 is slidably installed in the fixed seat 21 along the first direction, and the first rotating spindle 2213 is rotatably installed in the axial feed seat 2222. The fixed seat 21 and the axial feed seat 2222 are both hollow shell structures. This arrangement can not only reduce the weight of the two, but also make the fixed seat 21, the axial feed seat 2222 and the first rotating spindle 2213 sequentially installed from the outside to the inside, making the structure of the device more compact. Figure 19 The body of the first rotation driving source 2211 is fixed on the axial feed seat 2222, and its power output end is connected to one end of the first rotation main shaft 2213 through the reducer, the driving gear and the first driven gear 2212, and the other end of the first rotation main shaft 2213 is fixedly connected to the radial slide 2232, so that the first rotation driving source 2211 can drive the first rotation main shaft 2213, the first radial driving assembly 223 and the inner surface cutting mechanism 23 to rotate simultaneously.
