Machining method for antenna housing

Abstract

The invention discloses a machining method for an antenna housing. The machining method comprises the following steps of: 1) drilling holes in a cylinder, turning the internal diameter and external diameter of the cylinder, linearly cutting lateral through grooves, milling filler strips and clamping strips, turning a filling ring and milling through grooves on the filling rings; 2) performing sand-blowing treatment on the internal diameter of the cylinder, the lateral through grooves on the cylinder and the external diameter of the filling ring, polishing the filler strips and the clamping strips, and after the sand-blowing treatment and the polishing treatment are finished, washing the cylinder; and 3) spray-coating a primer on the surfaces of the internal diameter of the cylinder, the lateral through grooves on the cylinder and the external diameter of the filling ring subjected to the sand-blowing treatment, placing the cylinder in a drying oven at the temperature of 80 to 100 DEG C, and baking the cylinder for 2 to 2.5h. Field quality tracking and underground 180 DEG C*(100 to 130)MPa*3h tests show that the machined antenna housing has reliable and stable quality, high production efficiency and the qualified rate of over 90 percent.

Description

technical field [0001] The invention relates to the field of material processing, in particular to a processing method for a radome. Background technique [0002] The radome is a key part of deep underground monitoring instruments for oil, natural gas, coal and other energy sources. The radome is mainly assembled at the front end of the monitoring instrument. Electromagnetic signals ensure the accuracy of the signal source and improve the accuracy of underground monitoring. This requires that the radome cannot be magnetized by deep electromagnetics to protect the sending and receiving of working signals. Therefore, the radome uses non-magnetic stainless steel as the cylinder body, and high-temperature glass fiber Epoxy resin is used as the lining to ensure the monitoring works around the clock, prolong the service life of the monitoring system, improve its working reliability, and reduce the life cycle cost. [0003] The lining of the radome is generally processed by hand l...

AI Technical Summary

Problems solved by technology

[0003] The lining of the radome is generally processed by hand lay-up FRP, inlaid glass-ceramic laminates, etc., which not only has low production efficiency and unstable quality, but also has a complicated production process and high cost, which cannot meet the needs of deep monitoring of high temperature, High pressure and other use requirements
