Description

Technical Field

[0001] This utility model belongs to the field of dust removal technology for plasma cutting machines, specifically an adaptive dust removal device for plasma cutting machines. Background Technology

[0002] Plasma cutting machines are machines that use plasma cutting technology to process metal materials. Plasma cutting uses the heat of a high-temperature plasma arc to melt the metal part or part of the workpiece at the cut, and uses the momentum of high-speed plasma to remove the molten metal to form a cut. Plasma cutting machines will produce some dust during the cutting process.

[0017] The inner wall of the connecting sleeve 8 is slidably connected to the outer wall of the connecting rod 7. The second fastening screw 11 is threadedly connected to the side wall of the connecting sleeve 8. The second fastening screw 11 is inserted into one end of the connecting sleeve 8 and connected to the connecting rod 7 by a clamping method. When the second fastening screw 11 is loosened, the connecting sleeve 8 can move up and down on the connecting rod 7.
