High-speed aircraft empennage underwater laser processing device

Abstract

The invention discloses a high-speed aircraft empennage underwater laser processing device. The device comprises a cold water machine 1, a liquid tank 2, a clamp 3, fixing nuts 4, clamping grooves 5,a fixed rod 6, a fixed base 7 and a filter 8, wherein the two ends of the liquid tank 2 are provided with a water inlet and a water outlet respectively; the water inlet and the water outlet are connected with the filter 8 and the cold water machine 1 through pipelines to form a circulation system; the temperature and the flow speed of the whole system are controlled by the cold water machine 1; residues in a working solution are filtered by the filter 8, so that the cleanness of the working solution is guaranteed; the fixed rod 6 is provided with the clamping grooves 5 for positioning the clamp 3; and the two fixing nuts 4 are matched with the clamping grooves 5 to enable the clamp 3 to be fixed more firmly. Under the coupling action of multiple energy fields such as light, temperature, flow field and the like, efficient and high-quality cutting of an empennage sample piece is realized. The empennage sample piece is controllable in immersion depth, flow field speed and temperature; andthe device is simple in structure and simple and convenient to operate.

Description

technical field [0001] The invention relates to the field of laser processing, in particular to an underwater laser processing device for a high-speed aircraft empennage. Background technique [0002] As an important part of precision-guided weapons or smart weapons, the tail fin is used to provide lift for the flight of the projectile, generate a stabilizing moment, and ensure the stability of the flight of the projectile. Generally speaking, the working environment of the empennage is extremely harsh. Therefore, the empennage is mostly made of high-hardness aluminum alloy, light alloy, composite material or high-strength steel, titanium alloy and other materials. At present, the manufacturing of empennage usually adopts the following several processes: (1) mechanical cutting; (2) precision casting or die-casting; (3) water jet cutting; (4) wire electric discharge machining. However, the above-mentioned processing techniques have the following processing defects: (1) The ...
