Electro-hydraulic combined supply device

Abstract

The invention discloses an electro-hydraulic combined supply device. The device comprises an insulating base, an electro-hydraulic combined supply base, an electro-hydraulic combined supply pipe terminal and an electro-hydraulic combined supply pipe, the insulating base is fixedly connected with a spindle shell, the top end of the electro-hydraulic combined supply base is fixedly connected with the insulating base, a working fluid pipe connector and a binding post are arranged on the electro-hydraulic combined supply base, and a terminal connector is arranged at the bottom end of the electro-hydraulic combined supply base. The working fluid pipe connector and the terminal connector are respectively communicated with a flow channel in the electro-hydraulic combined supply base, and when theterminal connector is connected with the top end of the electro-hydraulic combined supply pipe terminal in a clamping manner, the flow channel in the electro-hydraulic combined supply base is communicated with a flow channel in the electro-hydraulic combined supply pipe terminal. The flow channel in the electro-hydraulic combined supply pipe terminal is further communicated with a liquid flushingbin in an electric discharge machining electrode knife handle through the electro-hydraulic combined supply pipe; and the binding post, the electro-hydraulic combined supply base, the electro-hydraulic combined supply pipe terminal, the electro-hydraulic combined supply pipe and the electric discharge machining electrode knife handle are all conductive and electrically conducted, and the electricdischarge machining electrode knife handle and a main shaft knife handle connector are insulated by arranging an insulating layer. According to the device, the usability and applicability of electricdischarge machining are improved.

Description

technical field [0001] The invention relates to the technical field of electrical discharge machining equipment, in particular to an electro-hydraulic combined supply device. Background technique [0002] Discharge machining is a kind of special machining technology, including electric discharge machining and electric arc machining, and is widely used in mold manufacturing, aerospace and other industries. EDM can be used to process superhard materials and complex-shaped workpieces that are difficult to process by traditional cutting methods. It is usually used to process conductive materials and can be processed on difficult-to-machine materials such as titanium alloys, tool steels, carbon steels, and cemented carbides. Complex cavities or contours. Generally, arc machining in electrical discharge machining can achieve high machining efficiency, but at the same time, there is a limitation that the machined surface is relatively rough, while the quality of electrical dischar...

Problems solved by technology

The existing electric discharge machining electrode holders, especially the electric arc machining electrode holders often require the machine tool spindle to have a central flushing function, and / or install a power supply through the machine tool spindle, and / or directly install a power supply on the electric arc machining tool holder, but do not Not all machine tool spindles have the function of central flushing. Installing the power supply through the machine tool spindle also requires an additional special insulation structure, which increases the complexity of the machine tool spindle structure. During the cutting process, it is necessary to manually install or disassemble the power supply and liquid supply parts, which further affects the automation of the equipment
