BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for assembling a vehicle drive shaft in which joint units such as a bell type and a tripod type constant velocity joint are provided at both ends.

(Prior Art) Conventionally, in the assembly line of this type of drive shaft, as shown in Japanese Patent Laid-Open No. 61-284333, the drive shaft is intermittently fed to a plurality of assembly stations in a horizontal position and each assembly is assembled. Each component of the joint unit is assembled to the drive shaft by an assembling device arranged on the side of the station.

In this structure, after assembling a part of the components of the first joint unit to be provided at one end of the drive shaft, the components of the second joint unit to be provided at the other end of the shaft at the next assembling station. Part of the drive shaft is assembled, and the first and second joint units are assembled to both ends of the drive shaft alternately.

(Problems to be Solved by the Invention) In the above-mentioned conventional technology, since the long drive shaft is conveyed in a horizontal position, it is necessary to configure the conveyance path to be wide, which increases the line space. If a heavy component is attached to one side, the weight balance of the drive shaft may be lost, making it difficult to convey the drive shaft in a stable posture. The first object of the present invention is to make it possible to stabilize the transport posture of the drive shaft.

Further, each assembling station is provided with a backup unit for centering and holding the drive shaft at the end opposite to the end for assembling the parts. If the constituent parts of the second joint unit are alternately assembled to a part,
And one of the second joint units, for example, when the model of the second joint unit is changed, in addition to the specification change of the assembling device provided in each assembling station for the second joint unit, each pair for the first joint unit is changed. It is necessary to change the specifications of the backup unit provided in the attachment station to those corresponding to the components of the second joint unit assembled in the assembly station in the preceding stage, which takes time and labor, and the problem is solved. Is the second object of the present invention.

In order to solve the first problem, it may be possible to convey the drive shaft to each of the assembling stations in a vertical posture. In this case, the parts are assembled from above in the vertical posture of the drive shaft at the assembling station. And the parts easily fall off from the assembling device, and the dropped parts fall into the rubber boot that covers the opening on the drive shaft side of the joint unit, so it is necessary to remove the missing parts. It is time-consuming and it is the third object of the present invention to solve this problem.

(Means for Solving the Problems) The invention of claim 1 is a method for assembling a vehicle drive shaft, wherein joint units are provided at both ends in order to solve the above-mentioned problems, and the components of these joint units are driven. In a case where a drive shaft is sequentially conveyed to a plurality of assembly stations to be assembled to a shaft, the plurality of assembly stations are provided at one end of the drive shaft, and a first station group for a first joint unit and the other end of the drive shaft are provided. And a second station group for a second joint unit provided in the first station group, and the first station group conveys the drive shaft in a vertical posture with one end thereof facing down, and each set of the first station group.

The vertical position with the other end down and conveyed to the second station group, and at each assembly station of the second station group, each component of the second joint unit is attached to the other end of the drive shaft from below. The feature is that it is assembled.

The invention of claim 2 provides an apparatus used for carrying out the invention of claim 1, wherein a plurality of carriers for holding the drive shaft in a vertical posture in which the axis of the drive shaft is oriented in the vertical direction are provided along an annular transport path. A plurality of assembling stations, which are movably provided and each of which has a predetermined assembling device for assembling each component of the joint unit to a drive shaft and a supply device of each component, are circumferentially arranged on the conveying path. And a drive mechanism for intermittently feeding each carrier in the circumferential direction of the transport path while stopping each carrier at each assembling station, and the plurality of assembling stations at one end of the drive shaft.

A backup unit for centering and holding the outer shaft of the joint unit is provided.

(Operation) By conveying the drive shaft in a vertical position, the width of the drive shaft can be made as narrow as possible regardless of the length of the drive shaft, and the drive shaft remains in the vertical position at each assembly station. As the components of the joint unit are assembled, the parts are assembled in the vertical direction, and the assembly device and backup unit can be arranged in three dimensions in the assembly station, and the flat space of the assembly station can be reduced, resulting in space efficiency. Can be improved.

Further, even if the weight of one side of the drive shaft increases due to the assembly of the parts, this weight acts in the axial direction of the drive shaft in the vertical posture, and the posture of the drive shaft does not become unstable.

Furthermore, until the assembly of the first joint unit to one end of the drive shaft is completed in the first station group, the components of the second joint unit are not assembled to the other end of the drive shaft, and the first station is not assembled. The backup unit for centering and holding the other end side of the drive shaft provided in each assembly station of the group may be configured to directly hold the other end of the drive shaft, and the backup unit can be changed by changing the model of the second joint unit. There is no need to change the specifications. In addition, the backup unit provided in each assembly station of the second station group holds the outer shaft of the first joint unit because the assembly of the first joint unit has been completed in the first station group. The shape of the outer shaft portion does not change significantly depending on the model of the joint unit. Therefore, it is not necessary to change the specifications of the backup unit of the second station group by changing the model of the first joint unit. And the second
The model change of each joint unit can be dealt with only by changing the specification of the assembling device arranged at each assembling station of the corresponding station group.

Further, in the first station group, one end of the drive shaft is placed downward, and each component of the first joint unit is assembled to the one end from below, then the drive shaft is inverted, and in the second station group, the other drive shaft is Since the other end of the second joint unit is likewise assembled from the bottom with the end facing down, it is difficult for the parts to fall off during the assembly work, and even if the parts fall off, the parts are driven. The parts do not fall between the rubber boots as they fall below the shaft and are assembled from above, and the troublesome work of taking out the fallen parts from the rubber boots when reassembling is not required. .

Further, according to the assembling apparatus of claim 2, the drive mechanism is operated to intermittently feed each carrier in the circumferential direction of the annular transport path, so that the drive shaft held in a vertical posture by each carrier is transported to the transport path. Are sequentially transported to a plurality of assembling stations arranged in the above, and at each of the assembling stations, each component of the joint unit supplied from the supply device is assembled to the drive shaft by the assembling device.

In this case, it is possible to convey the drive shaft along a straight conveying path, but this requires a return path from the end of the conveying path to return empty carriers to the beginning of the conveying path. The length of the circulation path of the carrier consisting of
The number of sum carriers obtained by dividing the length of this circulation path by the arrangement pitch of the assembling stations is required, and the number of carriers used increases and the facility cost increases.

On the other hand, in the assembling apparatus of claim 2, since the drive shaft is conveyed along the annular conveying passage, the return passage is unnecessary, and the number of carriers used is about 1/2 that of the linear conveying type. , The equipment cost can be reduced.

Further, the drive shaft set in the carrier at the loading station is sequentially conveyed to each assembling station of the first station group, the first joint unit is assembled at one end thereof, and then each assembly of the second station group is assembled. The drive shafts are sequentially conveyed to the stations, the second joint unit is attached to the other end, and then the assembled drive shafts are taken out from the carrier at the payout station, and the carrier is returned to the input station in an empty state. An unassembled drive shaft is set in the carrier,
The above operation is repeated.

Further, in the first station group, the drive shaft is conveyed in a vertical position with one end thereof facing down, the components of the first joint unit are assembled from the lower end to the one end, and then the drive shaft is installed in the reversing station. The drive shaft is conveyed to the second station group in a vertical position with the other end facing down, and the other end is assembled with the components of the second joint unit from below because the drive shaft is inverted and reset to the carrier.
