Abstract

The invention relates to the technical field of magnetic abrasive finishing, and particularly relates to an electrochemical ultrasonic magnetic combined abrasive finishing machining crankshaft systemand method. An ultrasonic vibration device is connected with one end of a crankshaft, a driving device is connected with the other end of the crankshaft and drives the crankshaft to rotate, a transverse feeding device drives a magnetic abrasive finishing follow-up device to reciprocate along the axis of the crankshaft, the magnetic abrasive finishing follow-up device is connected with a magnetic brush, the magnetic brush follows the surface of the crankshaft to be ground through the magnetic abrasive finishing follow-up device, a copper bar and a nozzle of an electrochemical reaction device are fixedly connected to the magnetic brush, an electrolytic bath is connected with the copper bar and the nozzle through pipelines, the copper bar is connected with a negative electrode of a direct-current power supply of an electrolytic polishing device, a positive electrode of the direct-current power supply is connected with a carbon brush of a carbon brush assembly, and the carbon brush is abutted against the crankshaft. Electrochemical finishing machining and axial ultrasonic vibration assisted magnetic abrasive finishing machining are combined, finishing machining of the hard alloy crankshaft is achieved, and the machining efficiency and the surface quality are substantially improved.

Description

technical field [0001] The invention relates to the technical field of magnetic particle grinding, in particular to a crankshaft system and method for electrolytic ultrasonic magnetic particle composite grinding and finishing. Background technique [0002] Ultra-precision machining technology is one of the important symbols to measure the level of science and technology of a country, and has become the most important part of the machinery manufacturing industry. As one of the most important parts in the engine, the precision of the crankshaft directly determines the performance of the engine, especially in the field of high precision and high speed. The surface quality of the crankshaft determines the precision of the crankshaft. Therefore, due to the increasingly stringent requirements for the accuracy of the crankshaft in the field of high speed and high precision, the ultra-precision grinding process of the precision crankshaft has received more and more attention. As o...
