用可调垫铁(附图)来装夹薄盘工件,可避免工件的摆动。垫铁可任意调整来夹持不同的工件。制作夹具时,先将内外螺纹车好,然后在铣床上铣出三条互为120°的槽,其宽度稍大于卡爪宽度,最后将螺旋副旋紧,在平面磨床上磨两平面。有条件也可将垫铁淬火后再磨,以减少变形。 With adjustable horns (with photos) to install thin plate workpiece, to avoid the workpiece swing. Horn can be adjusted to hold different parts. When making the fixture, the internal and external screwdriver trucks are first good, and then three grooves of 120 ° to each other are milled on the milling machine. The width of the groove is slightly larger than the width of the jaws. Finally, the screw pair is tightened to grind two planes on the surface grinder. Conditioned horn can be hardened after grinding to reduce deformation.
