摘要
叙述圆柱形零件,例如柴油机气门顶杆、汽缸的活塞销等,在检测机构的作用下作旋转运动,以测得零件外形尺寸是否符合公差要求。这一运转机构的主要尺寸、运动位置通过数学模型和电算以及微机绘图加以说明。
The rotary motion of cylindrical parts,such as the top rod of air valve in diesel engine and the piston pin in cylinder,are started off by the effect of detecting mecharnism,so as to measure their contour dimensions and see if they are consistent with the demand of tolerance. The primary dimensions and position location in motion of this operating mechanism are illustrated by mathematical model and computerization and microcomputer graphics.
