Description

Technical Field

[0001] The present application relates to the technical field of machine tool auxiliary equipment, and particularly relates to a dust collection device for a dry graphite processing machine tool. Background Art

[0002] Graphite has the properties of wear resistance and high temperature resistance and is widely used in equipment that requires wear resistance and high temperature resistance. However, during the processing and manufacturing of dry graphite, when a tool cuts the graphite material, a large amount of dust and debris are generated. These dust and debris not only pollute the environment but also pose a threat to the health of operators.

[0003] Currently, the related technology is to set a dust collection port above the machine tool. Although this method can collect a part of the graphite dust, the effect is not ideal. Especially near the spindle box of the machine tool, due to the lack of an effective dust removal device, dust and debris are likely to accumulate, affecting the normal operation and processing accuracy of the machine tool.

[0004] Therefore, how to improve the dust collection effect of graphite dust is a technical problem that needs to be solved by those skilled in the art at present. Utility Model Content

The pipe clamps 7 are provided with adjusting rods. The pipe clamps 7 can be loosened and tightened through the adjusting rods, which facilitates the disassembly of the corrugated hose 6. By connecting the outlet end 221 of the dust collection pipe 2 and the suction port of the vacuum cleaner 3 through the corrugated hose 6, it helps to ensure that when the dust collection pipe 2 moves with the main spindle box 100, the moving space is not limited by the interference of the connecting pipeline.

[0053] The working process of a dust collection device for a dry graphite processing machine tool is as follows: Start the vacuum cleaner 3 to start suction, start the tool of the machine tool to rotate to process the dry graphite workpiece. The graphite powder generated by the tool processing the graphite workpiece quickly enters the dust collection pipe 2 under the action of the negative pressure at the inlet end 211 of the dust collection pipe 2, and enters the vacuum cleaner 3 through the corrugated hose 6. When the main spindle box 100 moves up and down and left and right, the dust collection pipe 2 moves with the main spindle box 100. One end of the corrugated hose 6 undergoes elastic deformation and moves with the outlet end 221 of the dust collection pipe 2, and the other end swings on the pipe support 31. The inlet end 211 of the dust collection pipe 2 continuously collects the dust generated by the tool processing the workpiece and enters the vacuum cleaner 3 through the corrugated hose 6.
