Magnetic particle grinding machine and method suitable for surfaces of crankshafts and non-standard shaft entities

Abstract

The invention relates to the technical field of magnetic particle grinding, in particular to a magnetic particle grinding machine and method suitable for the surfaces of crankshafts and non-standard shaft entities. The magnetic particle grinding machine comprise a machine frame, a driving device, a lifting device, a magnetic particle grinding follow-up device and a magnetic brush, wherein the machine frame, the driving device, the lifting device, the magnetic particle grinding follow-up device and the magnetic brush are installed on the machine frame; the driving device is connected with a crankshaft or a non-standard shaft and drives the crankshaft or the non-standard shaft to do rotation motion; the lifting device is connected with the magnetic particle grinding follow-up device and drives the magnetic particle grinding follow-up device to reciprocate along the axis of the crankshaft or the non-standard shaft; the magnetic particle grinding follow-up device is connected with the magnetic brush, and the magnetic particle grinding follow-up device enables the magnetic brush to follow the surface of the crankshaft or the non-standard shaft to be ground and to be kept at the machining distance of 2-3 mm all the time, so that the surface of the crankshaft or the non-standard shaft to be ground is ground; and the quality and uniformity of the surface of the crankshaft can be guaranteed, the to-be-machined surface can be machined conveniently, the cost is low, and the grinding effect is good.

Description

technical field [0001] The invention relates to the technical field of magnetic particle grinding, in particular to a magnetic particle grinding machine and method suitable for solid surfaces of crankshafts and non-standard shafts. 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. ...

AI Technical Summary

Problems solved by technology

When the special grinding machine processes crankshafts and non-standard shafts, the effective processing area of ​​the grinding wheel and the abrasive belt is limited, and the corresponding shaft surface can only be processed in two dimensions; the special grinding machine has the disadvantages of complex structure, cumbersome operation, and expensive equipment.
