Abstract

PURPOSE:To enable automatic assembling while prevent a foreign matter from remaining in a cylinder block by carrying out clamping when a connecting rod cap on a cradle is lifted up and brought into contact with the bottom face of a connecting rod, after a crankshaft on a supporting table is lifted up by means of a clamping bogie and brought into contact with the bearing face of said cylinder block. CONSTITUTION:When a lifting base 26 is lifted up by means of a hydraulic cylinder 27, a positioning pin 29 is fitted in the positioning hole 30 of a clamping bogie 20 to determine positioning. Then, the top of the base 26 is brought into contact with the bottom face of a bogie 21, lifting up the body 21. Thereby, the crank shaft 7 is lifted up together with the bogie 20, a journal is brought into contact with the bearing surface of a cylinder 10, and a crank pin is brought into contact with the metal 8 of a connecting rod 3 and stops rising. However, the bogie 20 continues to rise and the bottom ends of a pin 35 and a pressing bar are projected out below the bogie body 21 in a retracting condition. Then, as a connecting rod cap 5 is brought into contact with the bottom face of the crank pin or connecting rod 3, the bogie 20 is stopped. By detecting this, the cylinder 27 is stopped and, as a nut runner 48 is operated and a clamping member 47 is rotated, a nut 6 is brought into contact with a bolt and screwed over, it simultaneously combining the cap 5 with the connecting rod 3.
