Mechanical Design And Structure Analysis Of Four Axis Precision Grinding Machine

Precision engineering is an important standard to scale a Country's manufactory ability. Precision engineering technic is a compositive technology. It needs to be kept developing, and it's not an open technology, it can not be copied, as it determined who will win the future. Recently, the NC machine tool has been used widely for manufacturing's prospering. The proportion of NC machine in enterprise increased greatly.This thesis, studied grinder's mechanical design, used finite element analysis software to make static and dynamic analysis of grinder's stanchion, and optimized its structure. After these works above, we get satisfying result, it provide credible data for grinder's optimization designing.In this thesis, took grinder's moving system and grinder wheel correction structure for example, described their mechanical design process; took the stanchion for example, described its optimization process. In the part of structure analysis, introduced finite element techniques status and developing direction, made a brief of the steps for static and dynamic design. Through these work, we got the stanchion's static distortion and dynamic performance, and then optimized it by re-design the stanchion's mechanical structure.Main content is listed as following:(1) Mechanical design of Four Axis Digital Control Precision Grinding Machine and its key department: lathe bed, stanchion and grinding head.(2) Mechanical design of the Servo-driving system and the grinder wheel correction structure.(3) Static and dynamic analysis of stanchion, made optimization of stanchion base on the result of analysis.
