Piston assembly mounting apparatus for engine

A piston assembly mounting apparatus for an engine, comprising:

• a robot having two multi-joint arms movable in a predetermined range;
• a taking-out unit mounted at a free end of a first arm of the arms of the robot and configured for clamping and taking out one of a plurality of piston assemblies;
• and
• a fitting unit mounted at a free end of a second arm of the arms of the robot, configured for receiving and configured for clamping the one piston assembly taken out of the taking-out unit, and then configured for inserting the one piston assembly into a cylinder of a cylinder block,
• wherein the fitting unit includes:
• a first mounting plate mounted at the free end of the second arm of the robot;
• a first actuating cylinder mounted under the first mounting plate;
• at least two or more piston clampers arranged at predetermined angles around the first actuating cylinder and configured for clamping an outer side of the piston of the piston assembly taken out by the taking-out unit in accordance with an operation of the first actuating cylinder;
• a fitting cylinder that includes an actuating rod, is mounted on the first mounting plate with the actuating rod through a center of the second actuating cylinder, and is configured for fitting the piston assembly clamped by the piston clamper into the cylinder of the cylinder block;
• con-rod clamping units that are disposed at both sides of the first mounting plate, behind the second actuating cylinder, and are configured to selectively fix a con-rod of the piston assembly clamped by the piston clampers;
• and
• a piston clamper guide unit that is disposed between the first actuating cylinder and the con-rod damping unit and is configured for restricting an unclamping range of the piston clampers in accordance with a diameter of the cylinder of the cylinder block.
