Abstract
The invention discloses a center processor broaching tool drive hydraulic cylinder oil supply mechanism, which drives a plate-shaped cam to rotate through a driving device of a center processor tool change arm. An outline of the plate-shaped cam is synchronously in linkage with an oil supply cylinder to drive the oil supply cylinder to be actuated so as to provide hydraulic oil required by actuation of a broaching tool drive hydraulic cylinder. The center processor broaching tool drive hydraulic cylinder oil supply mechanism does not need an additional independent oil pressure driving system and thus saves production cost. In addition, by means of reciprocating motion of the outline of the plate-shaped cam matched with the oil supply cylinder, the problem of an extra driving time generated due to gas pressurization in the gas drive mode is resolved, and workpiece processing efficiency is improved.
