Research On High Speed Follow-up Grinding Wheel

The crank is the essential components of motor car engine and other internal combustion engine, the demand is big, the type is multitudinous, the processing precision requests high. Because the crank processing precision plays the decisive role to the engine performance, therefore its processing quality and the processing efficiency directly will affect the automobile product quality and the automobile industry development. The high speed follow-up grinding to enhances the production efficiency, the enhancement processing surface quality has the remarkable effect, is the current grinding technology trend of development.This article elaborated the domestic and foreign high speed grinding technology, Especially about the high-speed follow-up grinding technology development condition. Discussed the high speed grinder wheel slide to distinguish between the plain grinding machine wheel slide structure characteristic, its structure performance requirement and its high rigidity support structure design main point.Has carried system analysis on the wheel slide system equilibrium, has analyzed the transient equilibrium of rotor and on line equilibrium of grinder wheel high with emphasis. Through the analysis, the SBS equilibrium system solves the wheel slide system balance question best plan. And has conducted the system research to the wheel slide main axle supporting system, has analyzed the high speed bearing with emphasis, the main axle rigid question.Studies the engine bed with the finite element method the dynamic performance is current optimizes and improves the engine bed structure, the design development engine bed new product modern design method, but highspeed grinding high speed and the high dynamic performance requirement needs so. This article has established the wheel slide dynamics model in the analysis wheel slide design criterion foundation. Uses general finite element software ANSYS, has carried on the modality analysis, the harmony response analysis. Proposed according to the analysis result the wheel slide improvement design proposal, caused the grinding wheel center to respond along the horizontal direction displacement reduced a number magnitude.The research of high speed follow-up grinder wheel slide, has provided some valuable mentalities for our country engine bed profession in the high speed grinder development aspect, this regarding domestic in lacks the material in the high-speed grinding research aspect in the situation to have the extremely important reference value.
