1. A system for mounting a door hinge to upper and lower mounting portions of front and rear pillars of a vehicle body being transferred along a vehicle transfer line, the system comprising:
a jig frame installed to reciprocate in a vehicle width direction through a driving unit on a base frame outside the vehicle transfer line;
a rotation index installed on the jig frame and rotatable by a predetermined angle through a servomotor;
a vertical rotation shaft formed as a polyhedron having a cavity and coaxially connected to a rotation center axis of the rotation index along an up and down vertical direction; and
a pair of clamping units installed through a mounting plate to a base plate fixed to each side of the vertical rotation shaft, the pair of clamping units being disposed at upper and lower portions of the mounting plate and configured to clamp the door hinge,
wherein each of the pair of clamping units includes
a first driving cylinder fixedly installed to the mounting plate,
a movable block having a pair of tooling pins fitted into a tooling hole provided at the door hinge, and being connected to an operation rod of the first driving cylinder through a movable bracket, and
