As an auxiliary jig for assembling a module having a power train function by assembling parts such as a rear wheel, an air cleaner, a rear cushion, a main stand, and a muffler to an engine assembly, the applicant holds the engine by holding it with a clamp. In addition, a technique has been proposed in which the components of the engine are assembled in a posture that is easy to assemble while changing the posture of the engine using the receiving jig. (Application on January 13, 2000, Japanese Patent Application No. 2000-5096)

[0003]

However, when the engine is clamped and held as in the above-described technology, if the engine is different in form due to a difference in model, it cannot be held by a single receiving jig. However, since a dedicated receiving jig must be provided according to the model, there is a problem that equipment costs are increased and handling procedures and the like are complicated.

[0004] Therefore, the present invention, regardless of the type of model,
An object is to be able to assemble and support with a single jig.

[0005]

SUMMARY OF THE INVENTION To achieve the above object, the present invention provides an assembling work in which parts such as a muffler, a main stand, a rear cushion, and an air cleaner are sequentially mounted on a work to which a rear wheel and an engine are connected. As a receiving jig, a jig base provided on a conveyor that can travel along an assembly line, and a jig provided with a tire clamp mechanism that stands vertically rotatable with respect to the jig base and clamps a rear wheel. A main body and a work supporting mechanism capable of supporting a part of the clamped work and changing the posture of the work are provided.

[0006] When the tire clamping mechanism clamps both sides of the rear wheel tire, the rear wheels only differ in tire width and the like even if the model is different. And versatility is increased. In addition, a part of the work clamped by the work support mechanism is supported, and the posture of the work can be changed by, for example, making the work support mechanism vertically movable. At this time, since the tire clamp mechanism clamps a rotatable tire among the works, it is possible to change the posture of the work while the tire is clamped.

In addition, since the work receiving jig is provided on a conveyor that can travel along the assembly line, the posture of the work is adjusted to an optimum posture for each assembly station of components arranged along the conveyor or the like. If the work is converted, the assembling work is easy.

According to a second aspect of the present invention, a plurality of index holes are provided in the jig base, and a lock pin is provided in the jig body to lock the rotational position by inserting the jig body into the index hole when horizontally rotated to a predetermined position. I did it.

After the jig main body is horizontally rotated to a desired position in this manner, the lock pin is inserted into the index hole and fixed, so that the work is fixed in an easy-to-work direction to perform the assembling work. I can do it.

According to a third aspect of the present invention, the work supporting mechanism comprises a vertical cylinder type damper filled with oil, and a hand stop valve is provided in the middle of a hydraulic oil pipe connecting an upper end and a lower end of the cylinder type damper. By operating the hand stop valve, the rod supporting the work can be fixed at an arbitrary height.

By fixing the height of the rod supporting the work at an arbitrary position as described above, the posture of the work can be raised at an arbitrary angle. It can be assembled in a posture that allows easy work by standing up.
