摘要： An automatic piston installation apparatus according to the present invention includes a block positioning mechanism for positioning a cylinder block in a working area separated from a conveying line by moving the cylinder block in vertical and horizontal directions and by rotating the cylinder block around the crankshaft, a piston positioning mechanism for positioning the piston at an insertion position by moving the piston to the working area, a piston inserting mechanism for inserting the piston into a cylinder bore from above in the vertical direction, a cap positioning mechanism for positioning the connecting-rod cap by moving the connecting-rod cap to a fastened position in the working area, and a fastening mechanism for fastening the connecting-rod cap from below in the vertical direction. Thereby, the piston can be installed in various engines, such as inline-type and V-type engines, automatically, with a high degree of accuracy, and reliably, and productivity can also be improved.
