Abstract

The array type supporting auxiliary device comprises a base, a mounting frame and a mounting plate, the mounting frame is fixedly connected with the top of the base, the mounting plate is rotationally connected with the top of the mounting frame through a rotating rod, one side of the mounting frame is fixedly connected with a first motor, and the other side of the mounting frame is fixedly connected with a second motor. The output end of the first motor is fixedly connected with a speed reducer, the output end of the speed reducer is fixedly sleeved with a first gear, and one end of the rotating rod is fixedly sleeved with a second gear meshed with the first gear. And the top of the mounting plate is fixedly connected with a first supporting plate and a second supporting plate which are symmetrically arranged. Compared with chemical milling, the method has the advantages of simple process, high precision, high material removal rate and no environmental pollution; compared with mirror image type mechanical milling, mechanical chatter caused by cutting force in the machining process can be well restrained, the consistency of the thickness of parts can be guaranteed, and efficient, high-precision and low-cost machining of large-size weak-rigidity thin-wall parts can be achieved.

Description

technical field [0001] The invention relates to the technical field of electrolytic machining machine tools, in particular to an array support auxiliary device for electrolytic machining of large-sized weak rigidity thin-walled parts. Background technique [0002] Large thin-walled parts such as aircraft skins, military equipment shells, etc., are important components of equipment. They have important functions such as maintaining the structural shape, bearing aerodynamic loads during flight and transferring the loads to the internal skeleton, and ensuring the safety of aircraft personnel. They are modern weapons. Components that are in great demand for equipment, transportation, etc. With the continuous improvement of the modernization process, the working conditions of the aircraft are becoming more and more complex, and the requirements for the weight reduction rate, fatigue strength, and sealing reliability of the thin-walled parts used in it are getting higher and highe...
