Abstract

The invention relates to a mechanical servo drive main transmission device for a digital turrent punch press and belongs to the field of machine manufacturing. The device comprises a static platform, a dynamic platform provided with a punching head, first and second branch chains connected between the dynamic platform and the static platform, a guide sleeve which is fixedly connected with the static platform and limits the motion direction of the dynamic platform, a motion pair and a servo motor; both the first branch chain and the second branch chain have a moving pair or rotation pair which is actively driven by the servo motor; the two driving modes require different structure forms of the first and second branch chains; the motion pair between the dynamic platform and the guide sleeve is a following cylinder pair or moving pair; and the dynamic platform, the static platform, the guide sleeve and the first and second branch chains are connected to form the mechanical servo drive main transmission device for realizing the single degree of freedom punching motion in a direction allowed by the guide sleeve. The device has the advantages of simple structure, low manufacturing cost, high rigidity, high dynamic property, quick response, easy high-speed high-precision punching task realization, and the like.
