Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for assembling a motorcycle and an improvement of the assembly line.

[0002]

2. Description of the Related Art A motorcycle assembling method is disclosed, for example, in Japanese Unexamined Patent Publication No. 2-83125, entitled "Method and Apparatus for Assembling an Engine of a Motorcycle". As described above, the engine is mounted on a motorcycle frame, and more specifically, the engine is mounted while correcting the frame. That is, conventionally, a main frame was manufactured in advance by assembling pipes and beams in a lattice shape and welding, and an engine was mounted on the main frame together with front and rear wheels and the like.

[0003]

With the practical use of aluminum alloy frames, the weight of the body frame, especially the main frame, has been reduced. On the other hand, due to the demand for higher output, the engine tends to be heavier and heavier. . The main frame was slightly distorted due to the assembly, and when attempting to mount the engine on such a main frame, a problem that the engine could not be mounted properly came to occur. The countermeasure is the above gazette technology (mounting the engine while correcting the frame).

[0004] However, in the main frame manufacturing process, a straightening operation is performed to correct welding distortion. In addition to this, if the straightening operation is performed immediately before the engine is assembled, it becomes an overlapping operation. Productivity decreases. In addition, as the main frame has become lighter and more delicate, and the generated distortion has increased, a high level of skill has been required for straightening work just before the engine is assembled.

[0005]

Means for Solving the Problems Accordingly, the present inventors have:
The entire method of assembling a motorcycle has been completely reviewed to solve the above-mentioned problems, and has succeeded in establishing a technology that can also reduce the burden on workers, which has been a concern.

Attach wheels from below or beside the work floating on the floor. Attach equipment from the top or side to the work placed on the pallet of the ground conveyor. The work posture becomes easier, the burden on the worker is reduced, and the work efficiency is improved.

[0008] A motorcycle assembling method according to claim 3 is characterized in that in the wheel mounting process and the outfitting process, the pitch between the works is adjusted according to the type of the work at that time. Work is sent at a short pitch for vehicles with easy wheel mounting and outfitting, and works are sent at a long pitch for the reverse to improve production yield in mixed production.

According to a fourth aspect of the present invention, there is provided an motorcycle assembly line in which a semi-finished work of a motorcycle is suspended and conveyed, and an overhead conveyor provided with a work pitch adjusting mechanism, and a semi-finished work received from the overhead conveyor is placed thereon.
