Hole milling device and method for corrugated copper pipe outer conductor coupling type leaky coaxial cable

Abstract

The invention discloses a hole milling device and method for a corrugated copper pipe outer conductor coupling type leaky coaxial cable, and the device comprises a milling cutter, a groove milling die, and a lubricating oil atomizer. The groove milling die comprises a die body, and a through hole is formed in the axis direction of the die body. A milling cutter groove hole is formed in the upper section of the die body, an oil mist channel is further formed in the die body, an inlet of the oil mist channel is communicated with an air outlet of the lubricating oil atomizer, and an outlet of the oil mist channel is formed in one side of the milling cutter groove hole. According to the invention, the FRL air source is adopted to process the atomized lubricator, so that the liquid cutting fluid is atomized, and the atomized cutting fluid is blown to the cutting edge of the cutter to lubricate and cool by connecting the cable groove milling die with the oil mist hole channel through the pipeline, so that the groove opening of the cable outer conductor groove milling is smooth and burr-free, the electrical index of the cable is not influenced, and the service life of the cable is prolonged. The product quality is improved.

Description

technical field [0001] The invention relates to the technical field, in particular to a corrugated copper tube outer conductor coupling type leaky coaxial cable milling machine. Background technique [0002] At present, leaky coaxial cable (Leaky Coaxial Cable), referred to as leaky cable, English abbreviation LCX. Because this kind of cable has the dual function of coaxial cable and wire antenna, it is sometimes called Radiating Cable or Coaxial Antenna. The cable consists of four parts: inner conductor, insulating medium, outer conductor with periodic slots and sheath. During the internal transmission of the leaky coaxial cable, a part of the radio frequency signal is coupled to the external space through the outer conductor aperture; on the contrary, the radio frequency signal in the external space can also be coupled to the inside of the cable through the outer conductor aperture. Therefore, the leaky coaxial cable is also a radio frequency signal transmission line. An...

Problems solved by technology

During the wave cutting process of the outer conductor of the cable, the cutting edge of the tool cannot be lubricated with liquid, because the cutting fluid of the tool will enter the cutting hole, causing the cable to be damp due to the liquid between the insulator and the outer conductor of the cable, which seriously affects the signal transmission of the cable, and even causes the cable to fail. use
