摘要

A feed unit for moving parts over short distances has a four-bar chain forming a translating solid parallelogram having two parallel rigid opposite legs, one of which constitutes a base leg, connected to one another by elastic elements and a piezoelectric stack translator extending between and flexibly connected to the rigid legs for articulation relative to the rigid legs and oriented at an angle of incidence (alpha) with respect to a base leg that is less than 90� and greater than 45�.
