A grinding mechanism for automatic grinding and cleaning machine of crankshaft

Abstract

A grinding mechanism for an automatic crank shaft polishing and cleaning machine comprises a lathe bed, a working table, a workpiece feeding device and a plurality of grinding wheel assemblies, wherein each grinding wheel assembly comprises a grinding wheel, a grinding wheel adjusting rack and a grinding wheel feeding device; each grinding wheel adjusting rack and the corresponding grinding wheel feeding device can be matched with each other; each grinding wheel assembly is used for machining a corresponding workpiece to be ground; the grinding wheels in the grinding mechanism can be in linkage in the X, Y and Z directions in an adjusting moving process of three linear tracks; crank shaft workpieces move on a main X axis along with stroke of a sliding table; and through four-axis linkage, the workpieces with different sizes can be ground at various angles along curves of parting faces of the crank shafts. According to the grinding mechanism disclosed by the invention, the four grinding assemblies work simultaneously, four crank shaft workpieces can be simultaneously machined at a time, and through a plurality of device components which are matched with one another, the crank shaft workpieces are ground and cleaned fully automatically, manual assistance is not required in a grinding process, production efficiency is improved, and labor intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of crankshaft grinding and cleaning equipment, in particular to a grinding mechanism for an automatic crankshaft grinding and cleaning machine. Background technique [0002] At present, the crankshaft grinding and cleaning equipment in the prior art mainly has the following major problems: 1. The grinding head used in the grinding process of the existing crankshaft grinding machine can only move up and down or forward and backward. There is no way to adapt to the dimensional changes caused by different models. Cause the utilization rate of crankshaft grinding and cleaning equipment to be low. 2. The existing crankshaft grinder generally can only process one or two crankshafts at a time, and the work efficiency is low. If multiple devices are used, the floor space will be too large. Can not meet the production requirements of production. 3. The existing crankshaft grinding machine uses a spring structure t...
