Problems solved by technology
However, this lateral liquid supply method will inevitably have an impact on the electrode, so the liquid supply pressure cannot be too high, and the low-pressure liquid supply will cause the liquid circulation speed to be insufficient, thereby affecting the cooling and chip removal effects
Moreover, the processing of high-end workpieces such as turbine blades and other exhaust holes needs to be moved, rotated and turned over during the machining process, so it is necessary to adjust the liquid supply direction of the bamboo tube accordingly, even when the workpiece is moving, rotated and turned over. May come into contact with the bamboo tube with more serious consequences

The invention discloses a drilling cooling device for an electric spark small hole machine tool, which comprises a guide sleeve and a clamping seat, wherein the guide sleeve comprises a fixing part and a guide part which are arranged in a T shape, and hollow guide through holes are vertically formed in the middle positions of the fixing part and the guide part; a first groove is formed in the upper end face of the clamping seat, a second groove is formed in the lower end face of the clamping seat, the first groove and the second groove are coaxially formed and communicate with each other, and a liquid flow channel used for providing working liquid is formed in the side wall of the first groove; the guide sleeve penetrates through the first groove and the second groove from top to bottom, the fixing portion of the guide sleeve is arranged above the first groove in a covering mode, the guide portion of the guide sleeve is arranged between the first groove and the second groove in a penetrating mode, and a liquid flow gap is reserved between the guide portion and the side wall of the second groove. The flow direction of the working fluid is coaxial and the same as that of a tool electrode, and the purpose of promoting and improving the cooling and chip removal effects can be achieved by increasing the input pressure of the working fluid.
Description
technical field [0001] The invention relates to the technical field of electrode machining cooling, in particular to a drilling cooling device for an electric discharge small hole machine tool. Background technique [0002] CNC small hole EDM machine tool is one of the commonly used machine tools for modern high-end equipment manufacturing. The diameter of the electrode wire used for processing is very small (comparable to hair), and it is especially suitable for extremely small holes on hard materials with conductive properties. Therefore, it is widely used in tool and mold manufacturing industry, automobile manufacturing industry and aerospace industry. [0003] When the EDM small hole machining machine tool is processing, the tool electrode needs to rotate at high speed, and the high heat generated by the rotation and discharge needs to be cooled with a cooling medium such as deionized water. In the prior art, the method of cooling the running tool electrode is usually t...
