Special-shaped electrolytic machining machine with group holes distributed in a circular array

Abstract

The invention provides a special-shaped electrolytic processing machine for special-shaped group holes distributed in a circular array, comprising: a box body; a movement limiting plate, a groove on the movement limiting plate; a shaft; a driving plate, the lower end surface of which has a vortex groove; an electrode driving arm , the electrode driving arm is connected to the tool electrode device for installing the electrode, the upper end of the electrode driving arm has meshing teeth, the electrode driving arm is placed in the groove and meshes with the driving disk; gear A, gear A is fixed on the shaft; gear B, gear B Fixedly installed on the input shaft, gear B meshes with gear A; working fluid tank. Through the design of the vortex groove and the meshing teeth, the electrode drive arm engages the drive plate. When the input shaft inputs power, the top of the electrode drive arm is restricted by the drive plate and the two sides are restricted by the guide grooves on the movement limiting plate. The electrode drive arm can only Make radial movement in the guide groove. The advantage brought by this solution is that the electrode array will not produce circumferential and vertical displacements, ensuring the accuracy of the process action.

Description

technical field [0001] The invention relates to a special-shaped electrolytic machining machine with a group of holes distributed in a circular array, which belongs to the technical field of electrochemical machining. Background technique [0002] There are many methods for machining irregular-shaped group holes distributed in a circular array. However, the efficiency and processing cost of different processing methods vary greatly. The processing of mechanical drilling requires sequential processing of single holes, and its efficiency is too low. If there are dozens or hundreds of holes on the surface of the part, the processing speed will be unbearable, not to mention the complexity and complexity of mechanical drilling for special-shaped holes. Difficulty: Special-shaped holes can be processed by EDM, but the tool electrode consumes a lot, and the high temperature of the arc causes a large change in the performance of the part processing area. The laser processing metho...

However, the efficiency and processing cost of different processing methods vary greatly.

The processing of mechanical drilling requires sequential processing of single holes, and its efficiency is too low. If there are dozens or hundreds of holes on the surface of the part, the processing speed will be unbearable, not to mention the complexity and complexity of mechanical drilling for special-shaped holes. Difficulty; special-shaped holes can be processed by EDM, but the tool electrode consumes a lot, and the high temperature of the arc causes a large change in the performance of the processing area of ​​the part

The laser processing method is also a sequential processing of single holes, the thermal shock of the processing area is very large, and even its physical properties are changed
