Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0037] Such as figure 1 As shown, according to the characteristics of the workpiece (that is, the radome) and the processing requirements of the drawings, (1) Drill holes from the inside to the outside of the end frame of the radome, and the holes are evenly distributed on the circumference of the end frame of the workpiece; (2) Nest the large end of the radome Steel ring with a wall thickness of 10-20mm. The steel ring has through holes of φ8mm uniformly distributed in the circumferential direction; (3) The material of the workpiece is quartz-reinforced SiO2 ceramic matrix composite material. The frame length is 60-120mm; (4) Guided by the through hole on the metal steel ring, drill a φ8mm blind hole from the inside to the outside on the quartz-reinforced SiO2 ceramic matrix composite material. The positioning accuracy of the hole center: ±0.1mm, and ...

Abstract

The invention relates to a quartz strengthened SiO2 ceramic antenna housing drilling device and method, and designs an antenna housing digitally-controlled drilling device. The device comprises an upright post structure (1), a rotating table (2), an X-axis moving sliding table (3), a Y-axis moving sliding table (4), a Z-axis moving sliding table (5), a spindle component (6) and a cone-shaped workpiece special fixture (7). The device solves the problem that manual drilling of an antenna housing is high in labor intensity and low in precision, and practical application verification indicates that automatic drilling for a quartz strengthened SiO2 ceramic antenna housing can be realized by using the device and the method. Experimental data are provided for subsequently further processing of the antenna housing by designing a cutter and accumulating processing parameters.

Description

technical field [0001] The invention relates to a drilling device and a drilling method. Background technique [0002] Quartz / ceramic matrix composite material is an ablation-resistant composite material obtained by using ceramic as the matrix and reinforced by quartz fiber. It has the advantages of wear resistance, high temperature resistance, ablation resistance, etc., making it a heat-resistant structural part of composite materials. Because this material is a new type of material, especially the technology involves technical secrecy, there is no research report on its processing and application in military industry at home and abroad. [0003] A radome ( figure 1 ) and the metal connection ring are glued and assembled, it is necessary to use the prefabricated through hole of the metal connection ring as a guide, and process a Φ8mm blind hole on the inner wall of the radome of the quartz-reinforced SiO2 ceramic matrix composite material. At present, manual drilling is m...
