Dust monitoring device for composite material dry cutting machining

Abstract

The embodiment of the invention discloses a dust monitoring device for composite material dry cutting machining, and relates to the field of mechanical design and manufacturing. The dust monitoring device for the composite material dry cutting machining can remove dust automatically in a machining process, and comprises a controllable air pump which is connected with an air outlet of a dust removal box 2 through an air guide pipe and exhausts air from the dust removal box 2. An air inlet of the dust removal box 2 is connected with an air outlet of an isolating cover of a worktable on which a machine tool main shaft 5 is positioned through an air guide pipe. An air pump is connected with an air inlet of a main shaft protective cover 4 through an air guide pipe, and blows air into the main shaft protective cover 4. The main shaft protective cover 4 is of a semi-seal structure and is fixed to the machine tool main shaft 5; a tool which is mounted on the machine tool main shaft 5 extends through an air outlet of the main shaft protective cover 4. A dust concentration sensor 6 is mounted on the isolating cover of the worktable on which the machine tool main shaft 5 is positioned; a probe of the dust concentration sensor 6 extends into the inside of the isolating cover to detect the concentration of the dust inside the isolating cover. The dust monitoring device for the composite material dry cutting machining is applicable to dust removal of the composite material dry cutting machining.

Description

technical field [0001] The invention relates to the field of mechanical design and manufacture, in particular to a dust monitoring device for dry cutting of composite materials. Background technique [0002] Fiber-reinforced composite materials have many advantages such as high specific strength, large specific modulus, good dimensional stability, good corrosion resistance and fatigue resistance, low thermal conductivity, etc., and are widely used in aerospace, biomedical, transportation and Sports and military supplies. [0003] In practical applications, shaped fiber reinforced composite workpieces generally cannot be used directly. Further drilling and milling are required for assembly. Due to the hydrophilicity of its resin matrix, fiber reinforced composites are generally processed by dry cutting. Especially in the research and development of fiber-reinforced composite materials, it is necessary to conduct a large number of processing experiments in the laboratory in...
