Problems solved by technology
The main disadvantages of this method are: due to the large overall deformation area of the aluminum alloy material during the milling process, and the The hard alloy milling tool has a small diameter and poor rigidity. It is easy to break the knife due to the increased cutting amount caused by the deformation of the part, resulting in the scrapping of the part, increasing the processing cycle and increasing the processing cost.
The main disadvantages of this method are: due to the use of vacuum suction cups and compressed air pumps in the processing, the production investment is greatly increased and the cost of the enterprise is increased; Phenomenon, the gap cannot be milled through, which will form residual material in the lower part of the part, and it is difficult to ensure the consistency of the upper and lower dimensions of the gap, which will have a great impact on subsequent processing, increase the workload, and increase the processing cycle

Abstract
The invention relates to a processing method of a guide head crack array antenna. A clamping tool, a clamping tightening tool, an area limiting tool and a shape milling tool are used for processing, ablank is placed onto the clamping tooling, another blank is placed, the clamping tightening tool is placed on the blanks, then the area limiting tool is placed for milling the gap, and finally, the shape milling tool is used for milling the shape. Because of the fixing and limiting functions of the tools, the problem of low finished product qualified rate and low production efficiency in an existing processing method is solved.
Description
technical field [0001] The invention belongs to the field of antenna processing, and in particular relates to a method for processing a seeker slot array antenna. Background technique [0002] Commonly used transmitting antennas for UHF generally use slot array antennas and the like. The seeker crack array antenna used by the missile is to use the array antenna with a large number of cracks and gaps to play the role of the UHF transmitting antenna in the missile. This approach is often conducive to improving the guidance of the missile in a limited space. The accuracy of head guidance can also minimize the transmission power of the seeker's own radar, and at the same time, it also reduces the production cost of the missile. [0003] The seeker crack array antenna is usually formed on the rust-proof aluminum alloy sheet with a thickness of about 0.5mm, and the hole structure in the shape of the seeker crack array antenna is formed by high-speed milling. However, this kind o...
