The present invention can play positioning action, can realize again clamping.The mutual swing offset position of rotating disc and fixed disk is that the jack position of rotating disc displacement location latch is located by eccentric rotary axle rotation centering.Rotating disc is that location, little gap cooperates with the eccentric rotary axle, by eccentric rotary axle precise positioning, has determined the pivot position of fixed disk and rotating disc.When rotating disc when fixed disk forwards corresponding position (position in the position in I hole, location or II hole, location) to, nut on locking eccentric rotary axle and the rotating disc displacement locking member, after fixed disk and rotating disc pinning, just can process two eccentric revolving bodies at position A and position B respectively.
The present invention can realize processing eccentric revolving body, when it rotates same angle centered by the eccentric rotary axle, employing is located at the rotating disc big circumference, at the eccentric revolving body of small circumference processing, thereby dwindled position error on the rotating disc big circumference to the impact of the eccentric revolving body error of processing on the small circumference.
The invention solves and process respectively the mismachining tolerance that two eccentric revolving bodies need secondary clamping to bring, reduced to affect the factor of the precision of eccentric orfice distance, improved the eccentric throw precision.
