Electrochemical machine tool for removing internal-crossing array small-hole burrs

Abstract

The invention relates to the technical field of burr processing, in particular to an electrochemical burr-removing machine tool. The machine tool comprises a machine tool body, a power source, a control system, a safety detection loop, an electrolyte circulating system, tool clamps and a ladder electrode. The machine tool body is composed of an upper compartment and a lower compartment, and an electrolyte groove and an electrolyte temperature, pH value and conductivity detection probe are mainly placed on the right side of the lower compartment of the machine tool body; the upper compartment and the lower compartment on the left side of the machine tool body are communicated, and a stainless steel centrifugal pump is arranged on the left side of the machine tool body; the tool clamps, a pneumatic loop control system and a safety detection loop are arranged on the left side of the upper compartment of the machine tool; and a main power source switch, the power source, a detection instrument and a burr removing control system are arranged on the top of the right side of the upper compartment of the machine tool. A stationary cathode machining method is adopted, and an automatic positioning device of an array electrode is designed; it is ensured that the small-hole burrs can be removed from roots, and the problem that when the burrs are removed in the height direction, short circuit is prone to happening is solved; and the electrochemical burr-removing machine tool has the advantages of being high in machining efficiency, convenient to use, and high in similarity of machined small-hoe round angles

Description

Technical field: [0001] The invention relates to an electrochemical deburring machine tool, in particular to a structure and a control system of the electrochemical deburring machine tool. Background technique: [0002] During the machining process, there are many parts that will produce burrs in the inner cross array holes, such as the cylinder block of the engine, hydraulic valve parts, screw shaft of the steering gear, etc. This kind of parts has the characteristics of complex structure and poor accessibility. The removal of burrs has always been a headache. Now many factories rely on manual iron brushes to remove them. This method will cause burrs to fall off and enter small holes, causing blockage and It has the characteristics of low processing efficiency. Although there are various deburring methods at present, most of them are not suitable for removing burrs in small intersecting holes with poor accessibility. Electrochemical deburring is suitable for removing compl...

Problems solved by technology

In recent years, scientific research workers have proposed several types of electrochemical deburring equipment, which has greatly improved the efficiency and quality of deburring, but there is no machine tool for removing burrs from small holes in a circular array. If the existing If the equipment removes the burrs of the cross-array holes in the shaft holes, it needs to be repeated several times to remove the burrs from the workpiece, and it is difficult to locate the workpiece and distribute the electrolyte
