Array type supporting auxiliary device for electrolytic machining of large-size weak-rigidity thin-wall part

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 mi
