[0042] Working principle:

[0043] The plasma flame cutting machine for shipbuilding places the ship parts to be cut on a rotatable processing table 3. When the cutting angle needs to be adjusted, the rotatable processing table 3 can be driven by a rotating motor inside the workbench 2 to adjust the angle. The three-axis moving component 10 is located above the workbench 1. The X-, Y-, and Z-axis guiding system is composed of a first X-axis guide rail 4, an X-axis guide rail slide 5, a supporting upright 6, and a second X-axis guide rail 7. The precise position and trajectory of the flame cutting head 8 are controlled to achieve cutting of different positions of the ship parts. The negative pressure dust suction and chip removal component 11 is installed next to the three-axis moving component. The negative pressure dust removal box 13, the negative pressure dust removal pipe 14, and the mobile dust removal pipe 15 are used in combination, so that the negative pressure equipment generates negative pressure in the box. The smoke and metal chips generated during the cutting process are finally absorbed by the dust suction and chip removal net box 9 at the free end of the mobile dust removal pipe 15 through the connected pipeline. The dust collection and chip removal mesh box can be flipped according to the position of the cutting head to ensure efficient dust collection. At the same time, when the servo motor 23 drives the hinged shaft 22, the flip position of the dust collection and chip removal mesh box 9 can be adjusted. The dust collection mesh end of the dust collection and chip removal mesh box 9 can be flipped to two states, vertical and horizontal, and adjusted according to the actual dust collection position. When dusting sideways, the dust collection mesh end of the dust collection and chip removal mesh box 9 is in a vertical state, and when dusting from the top, the dust collection mesh end of the dust collection and chip removal mesh box 9 is in a horizontal state.

[0044] The connection between the cylinder part 17 and the first ear plate 16 and the design of the positioning cross bar 20 ensure the precise positioning of the mobile dust removal pipe 15 in the linear reciprocating adjustment position, closely coordinate with the action of the flame cutting head 8, effectively follow the cutting path, synchronously remove dust and chips, and move the cleaning assembly 12 along the X-axis. The electric push-pull rod 29 drives the push-pull connecting plate 30. The cleaning wiping cotton block 31 bonded to the plate automatically cleans the dust and debris remaining on the surface of the rotatable processing table 3 to keep the processing area clean. The design of the support column 32 and the auxiliary walking wheel 33 ensures the smooth movement of the cleaning assembly and the effective coverage of the rotatable processing table 3.
