Problems solved by technology
[0004] There are two main problems that need to be solved for quick disassembly and assembly parts. One is that the disassembly and assembly surfaces are severely worn due to the need for multiple disassembly and assembly during use; the second is that the friction between the contact surfaces is relatively large during the quick disassembly and assembly process , there may be a problem of jamming in disassembly and assembly; the third is that for the quick disassembly and assembly of the present invention, in the process of processing, unreasonable processing steps will lead to insufficient processing accuracy and low strength of the quick disassembly and assembly, and cracks appear on the surface and oxidation, affecting the use of quick release parts

Embodiment Construction
[0014] The present invention will be further described in detail below in conjunction with the examples, but the structure of the present invention is not limited to the following examples.
[0015] A quick disassembly and assembly part, including inserts, hoops, clamps, pins, retainers and torsion springs, wherein the inserts, hoops and clamps are made of aviation aluminum alloys, and the composition of aviation aluminum alloys includes: 0.25% Cr, 1.0% Fe, 0.5% Mn, 0.8% Mg, 6-8% Si, 1.0% Zn, 0.05-0.22% Ti, 5% Cu, 0.15% Pb.
[0016] The processing steps of the hoop are as follows: (1) Cut off a 40mm aluminum alloy bar with a saw machine; (2) Perform solid solution treatment on the cut aluminum alloy billet, the solution temperature is 530°C, and the solution time is 1 (3) Fix the blank on the platform fixture of the CNC lathe, and carry out rough turning, semi-finishing turning and finishing turning on both ends of the surface until the length is 38mm; (4) Change the clamping ...

Abstract
A method for quickly disassemble and assembling part the aeronautical aluminum alloy is use as that material, the processing step of the hoop comprises blanking, Solid Solution, External Circle, End face, intermediate annealing, milling straight grooves, milling center holes, Screw hole milling shoulder, milling hole, Deburring, hot dip plating, Final heat treatment, The processing steps of the plug-in include blanking, Solid Solution, External Circle, End face, intermediate annealing, milling limit surface, milling shoulder, milling hole, Trimming, deburring, hot dip plating, and final heat treatment. The processing steps of the card part include blanking, solid solution, turning end face, turning outer circle, intermediate annealing, milling arc groove, milling pin hole, milling limit protrusion, trimming, deburring, hot dip plating, and final heat treatment. The product has good wear resistance and small friction, and can absorb vibration and prevent oxidation in the final heat treatment process.
Description
technical field [0001] The invention relates to a small unmanned aerial vehicle part and a processing method thereof, in particular to a quick disassembly part and a processing method thereof. Background technique [0002] With the development of flight control systems and lithium battery technology, the flight stability and flight time of small UAVs have been greatly improved, and they are widely used in many technical fields, such as aerial surveying and mapping, power line inspection, agricultural monitoring, Police security and environmental pickets. [0003] Since small UAVs often need to be transported, and their multiple extension arms are not conducive to storage and transportation, the extension arms of small UAVs are designed to be quickly disassembled to facilitate transportation and storage. The quick release parts are used on the extension arm of the small UAV. One end of the extension arm is equipped with a rotating paddle and a brushless motor to provide powe...
