A method of sealing the passage between oil passages in the housing by using electrode machining

Abstract

The invention relates to a method for machining a channel between oil ways in a closed shell through an electrode. The method comprises the steps that 1, the electrode is placed in a cavity of the shell, a conductive rod is in a bent shape to form a conductive rod upper section, a conductive lower section and a conductive rod middle section, the conductive rod lower section is electrically connected with the electrode, the conductive rod upper section vertically stretches out of the outer side of the shell, and the conductive rod upper section is arranged on the side of the machining motion direction of the conductive rod lower section; 2, a machine tool drives the shell to move towards the machining direction to enable the electrode to machine the shell until the distance between the conductive rod upper section and the shell is within the range of 2 mm; 3, the machine tool drives the shell to move towards the direction opposite to the movement direction in the step 2, and the conductive rod upper section is rotated in 180 degrees; 4, the machine tool drives the shell to continuously move towards the machining direction until machining is completed. According to the method, the electrode can complete machining in a space of which the size is limited.

technical field [0001] The invention relates to the technical field of processing methods for oil passages in a closed casing, in particular to a method for processing passages between oil passages in a closed casing by using electrodes. Background technique [0002] In mechanical processing, the processing of the internal structure of the closed shell has always been a difficult problem for those skilled in the art. Since traditional mechanical processing usually needs to reserve a large processing space, the traditional processing method is obviously not suitable for the inside of the closed shell.

[0002] In mechanical processing, the processing of the internal structure of the closed shell has always been a difficult problem for those skilled in the art. Since traditional mechanical processing usually needs to reserve a large processing space, the traditional processing method is obviously not suitable for the inside of the closed shell. After years of development, people have invented a variety of methods suitable for the internal structure processing of closed shells, such as casting, EDM, etc.;

[0003] Among them, in all types of closed shell processing, the difficulty of internal processing of the fuel regulator shell is particularly prominent. Because the internal structure of the fuel Rectangular through cavity, due to the limited size design of some through cavities, the electrode is easy to interfere with the inner wall of the shell during EDM, and the processing efficiency is low, and some through cavities cannot even be processed by EDM process, so obviously It will affect the optimal design of the oil circuit. Therefore, it is necessary to develop a unique processing method so that the electrode can be processed in a space with limited size and improve work efficiency.
