ABSTRACT

The hydraulic pressure drills, power head is a kind of power type drilling machine which uses the hydraulic pressure actuation to progress for the traveling schedule. This aiticle introduces this drilling machine's unique feature emphatically、major technique parameter、power head organization composition、power drive plan、power head swiveling mechanism、advanced gear and hydraulic control system's design and so on. The article narrates the hydraulic pressure drill and power head's structure and principle of work, and gives a detailed introduction of the main parameter choice and the design calculation of the hydraulic pressure. The hydraulic pressure drills power head is the newest development of new series aggregate machine-tool general part in our nation. It has an independent processing unit, to drill deep holes in the cast iron, the steel and the non-ferrous metal. Its main feature is that the structure is compact, and it substitutes the past way to drill with truncates and the sliding table combination processing unit. It can be disposed as the rotation work table model aggregate machine-tool or the orthoscopic small aggregate machine-tool from the generatrix and so on, and it is widely used


Key words：Drilling, Power head, Hydraulic pressure
