摘要
从研磨轨迹、速度、压力的角度对(BQ型双偏心半球阀)阀芯研磨的球面度、表面粗糙度进行了分析,设计出一种能实现正弦波研磨轨迹的研磨机。该机可调节研磨速度和研磨压力,并通过弹性浮动支承结构保证阀芯与研具球面良好吻合,使研磨质量和研磨效率得到极大提高。
The spherical surface degree and surface coarse level of valvular- core lapping（ BQ double - postioner diagram） were analyzed from grind routine, velocity, pressure. The conclusion was obtained that sine routine is better for spherical surface degree and surface coarse level, and grind speed and pressure have a negative relation to spherical surface degree and a positive relation to grind efficiency. The mechanism of sine routine was worked out and the emulation picture, design elasticity float supporting mechanism was designed, the transmission system and mechanism was designed which velocity and pressure are adjustable with time. It can improve the welding quality and welding efficiency greatly.
