PURPOSE: An apparatus for supplying hydraulic pressure to a jig of a machine tool is provided to prevent oil leakage and abrasion and to reduce component replacement cost. CONSTITUTION: An apparatus for supplying hydraulic pressure to a jig of a machine tool comprises a first jig, a second jig, a first hydraulic pressure output hose(11), a second hydraulic pressure output hose, a joint block(30), a first hydraulic pressure input hose(21), a second hydraulic pressure input hose(22), and a hose guide unit. The first and second jigs support workpieces in a processing section or a set-up section. The joint block comprises a first passage for supplying hydraulic pressure to the first hydraulic pressure output hose; and a second passage for supplying the hydraulic pressure to the second hydraulic pressure output hose. The joint block is installed to rotate forward and backward with a palette exchanging device. The hose guide unit supports the first and second hydraulic pressure input hoses to be bent when the joint block rotates. |
