In the use of the work assembling transfer device having the above-mentioned structure, as shown in FIG. 1, the cylinder block CB of the engine body mounted on the work supporting base 3 for assembling work is attached to the work supporting attachment 8. And, while being supported by the required clamp (not shown),
The transport train 1 is moved along the guide rail 2 to, for example, the head assembly station, where the cylinder head CH
Shall be assembled. In this case, since the work support base 3 for assembly work is located at a low position laterally protruding from the transport train 1, even if the height of the cylinder block CB itself is considerably high, the floor surface F will be above the turntable 4. Since the height of the cylinder block CB supported by the top of the cylinder block CB becomes low, the work of assembling the cylinder head CH becomes very easy. In addition, for example, when assembling a manifold to a required side surface portion of the cylinder block CB, the rotary drive means 23 is operated to appropriately turn the turntable 4 so that the manifold assembly position of the cylinder block CB comes close to the worker. Rotate to work. In this case, since the worker can stand right next to the horizontal support base 3 that laterally extends from the transport train 1 as shown in FIG. 3, the distance from the side surface of the cylinder block CB is shortened, and the manifold is reduced.

Further, when viewed from FIG. 3, the auxiliary support table 4 is located on the left side of the worker standing right next to the assembly work support table 3, and the height of the auxiliary support table 4 is, for example, the chest of the operator. It becomes a degree.

Therefore, in the box body 27 of the sub-support 4 arranged at the use position P2, the cylinder head CH and other assembly parts necessary for assembly to the cylinder block CB,
Furthermore, necessary parts such as bolts and nuts are stored. In this case, as shown in FIG. 3, the pedestal portion 26 may be pulled out toward the front side along the guide rail 25 so that the box body 27 in which the assembly parts and the like are stored is located near the operator.

By arranging the auxiliary support 4 at the use position P2 as described above, the worker can take out the assembly parts and the like from the auxiliary support 4 in the standing work posture as shown in FIG. Assembling work such as assembling parts can be performed quickly and efficiently. After a series of assembling work of the cylinder head CH to the cylinder block CB is completed, one end of the sub-support base 4 may be pushed by hand to be stored in the original storage position P1. At this storage position P1, the sub-support 4
Is located on the opposite side of the work support base 3 for assembly work, so that the front-back width of the transfer device when not in use can be narrowed.

In the embodiment, the sub-support base is composed of the base part, the tray-shaped receiving base part, and the box body for accommodating the assembly parts and the like. It may be formed of a flat plate.
