The midpoint of the described hole heart line positioning I hole, II hole, location is positioned on the first eccentric rotary location Kong Kongxin and place, fixed disk center straight line.
The midpoint of the described hole heart line positioning A hole, B hole, location is positioned at the second eccentric rotary location Kong Kongxin and rotates on disk center's place straight line.
The present invention can play positioning action, can realize again clamping.The mutual swing offset position of rotation dish and fixed disk is to be rotated centering by eccentric rotary axle, and the jack position of rotation dish displacement location latch positions.Rotation dish and eccentric rotary axle are small-gap suture location fit, by eccentric rotary axle precise positioning, it is determined that the center of rotation position of fixed disk and rotation dish.When rotation dish forwards corresponding position (positioning the position in I hole or the position in II hole, location) on fixed disk, nut on locking eccentric rotary axle and rotation rotator shift locking member, after fixed disk is pinned with rotation dish, it is possible to process two eccentric rotary at position A and position B respectively.
The present invention can realize processing eccentric rotary, when it rotates same angle centered by eccentric rotary axle, adopt and position on rotation dish big circumference, small circumference is processed eccentric rotary, thus the position error reduced on rotation dish big circumference is on the impact of the eccentric rotary error of processing on small circumference.
The invention solves and process the mismachining tolerance that two eccentric rotary need secondary clamping to bring respectively, reduce affect eccentric orfice from the factor of precision, improve eccentric throw precision.
