Problems solved by technology
Due to the small size and large production volume of the centimeter-wave and millimeter-wave waveguide connecting pipe ferrules, such a processing method is likely to cause waveguide connecting pipe ferrules in the processing process, which not only has difficulties in holding, inaccurate positioning, and various processing surfaces of the parts. Difficulties such as non-vertical, labor-intensive, etc., and processing quality problems such as broken drill bit and inner cavity asymmetry are also prone to occur during the fitter's drilling and machining of the inner cavity. At the same time, there are also some problems for the processor such as drilling on small parts. Potential safety hazards such as easy scratches on fingers
Due to the unreasonable selection of the processing method of the waveguide connecting pipe ferrule, it is easy to have problems such as low yield rate, long processing cycle, and a substantial increase in processing cost in the process of waveguide connecting pipe ferrule.

Embodiment Construction
[0025] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:
[0026] When processing the waveguide connecting pipe ferrule used in electromagnetic wave radar, the following problems must first be solved: both the final processing accuracy, surface roughness and final processing quality of the waveguide connecting pipe ferrule must be satisfied, and the selected surface of the present invention must also be guaranteed. The advanced processing method can guarantee the quality and quantity, and complete the processing efficiently. The technical method adopted in the present invention is: on the Hi-V560M high-speed machining center, the 3A21 aluminum alloy raw material size ≠10mm×260mm×155mm used for the waveguide connection pipe ferrule is processed to ≠8mm±0.03mm×260mm×150mm (such as Figure 4 shown), and then use a pressure plate to combine it with a self-made mesh tooling board (such as Figure 5 shown) tightly clamped on ...

Abstract
The invention discloses a processing method for waveguide tube connecting tube hoops. The processing method is characterized in that a method of dividing an integer into parts is adopted to firstly mill out inner cavities of multiple waveguide tube connecting tube hoops on an integral aluminum alloy material, and then to perform around-milling along the outline of each waveguide tube connecting tube hoop, wherein each waveguide tube connecting tube hoop keeps certain margin with the aluminum alloy raw material, is separated from the aluminum alloy raw material, and is finally stripped off. Theprocessing method improves working efficiency, and increases the yield.
Description
technical field [0001] The invention relates to the field of precision microwave device processing, and relates to a method for processing a waveguide connecting pipe ferrule. Background technique [0002] At present, electromagnetic wave radar has been widely used in many aspects such as early warning, search, guidance, artillery sighting, battlefield surveillance, and identification of friend and foe. Transmission of ultra-high frequency electromagnetic waves, through which pulse signals can be transmitted to the destination with minimal loss, is an extremely important component in electronic equipment such as microwave and millimeter wave radio communications, radar, navigation and other radio fields. The steady development of radio technology has also made waveguides have many fixed specifications and models. Users can select the specifications and models corresponding to the inner diameter of waveguides according to the wavelength of the transmitted signal, and then cha...
