Description

[Detailed Description of the Invention] (Industrial field of application) The present invention assembles parts constituting a rear axle assembly, such as a differential and a drive shaft, into one body, and also assembles the assembled rear axle assembly to a vehicle body. For assembling a rear axle assembly for a vehicle.

(Prior Art) A rear axle assembly (rear axle) generally includes a differential in which a differential gear is incorporated, drive shafts connected to the left and right of the differential, a brake drum, and the like, and is assembled to the drive shaft. It is mainly composed of an attached axle and a differential member (suspension member) for fixing the differential to the vehicle body. (Complete list of Automotive Engineering Volume 9, Power Transmission Device; see Figure 5.4 on page 311 issued by Yamakaidou on November 20, 1980) The rear axle assembly consisting of the above-mentioned components is
Conventionally, assembling is done on a jig stand located away from the assembly line of the vehicle body, and after assembly is completed, it is transferred to a mount stand laid on the assembly line by a transfer means such as a hoist, where the rear axle is installed. The assembly is attached to the car body. Such a conventional rear axle assembly assembling apparatus is shown in FIGS.

FIG. 4 is a view showing a jig base 1, which is substantially T-shaped in a plan view as a whole, and is provided with a support jig 2 for supporting the differential A in the central portion. A support jig 3 for supporting the differential member B is provided in front of the jig 2. Further, a supporting jig 4 for supporting the drive shaft C and a supporting jig 5 for supporting the axle D are provided on the left and right of the supporting jig 2, respectively. On such a jig stand 1, as shown in FIG. 5 (A), the operator M manually assembles the rear axle assembly constituent members such as the differential A. After the assembling is completed, the hoist 6 shown in FIG. 5 (B) lifts the hoist 6 and conveys it to the assembling table 7, where the assembling table 7 is raised with respect to the vehicle body W conveyed by the conveying device 8 and the rear axle. I am trying to assemble the assembly.

(Problems to be solved by the invention) However, in such a conventional rear axle assembly assembling apparatus, it is necessary to transfer the rear axle assembly using the hoist 6 as described above. The part of the boot E attached to the drive shaft C may be broken. Then, when the drive shaft C is inserted into the axle D and the differential A by the jig base 1, the worker must work while holding the drive shaft C with both hands. The directionality of insertion of C cannot be obtained, and as shown in FIG. 5 (D), the axle D and the bearing seal portion F of the differential A may be damaged, and this assembly work must be done carefully. I had to do it.

The present invention has been made in view of the above-mentioned problems of the prior art, and enables the members constituting the rear axle assembly to be easily assembled with each other, and after the assembly is completed, the rear axle assembly can be assembled directly to the vehicle body. The purpose of this is to assemble the rear axle assembly quickly and efficiently.

(Means for Solving the Problems) The present invention for achieving the above-mentioned object is to install an assembly table by arranging the assembly table so as to be vertically movable toward the conveyed vehicle body, and A support jig for supporting the differential is provided on the assembly table, and a first slide having a support jig for supporting the differential member is slidably attached to the assembly table, and a second slide having a support jig for supporting the drive shaft. Is slidably attached to the assembly table in a direction substantially perpendicular to the first slide, and a third slide having a supporting jig for supporting an axle is slid on the assembly table in the same direction as the second slide. An apparatus for assembling a rear axle assembly, comprising a supporting jig movably attached to the supporting jig for supporting the axle, and swinging means for changing the posture of the axle.

(Operation) With the differential, the differential member, the drive shaft, and the axle that form the rear axle assembly mounted on the support jig, the first, second, and third slides are advanced toward the differential to facilitate the rear axle. The assembly can be assembled. Further, since these components are assembled on the assembly line installed below the vehicle body on the transportation line for transporting the vehicle body, the assembled rear axle assembly can be assembled on the vehicle body as it is. At this time, since the posture of the accelerator can be changed by the swinging means, the accelerator can be prevented from hitting the vehicle body first, and the rear axle assembly can be surely prevented from being damaged. Can be assembled to.

A second slide 15 provided with a support jig 14 for supporting the drive shaft C adjacent to the left and right of the support jig 11 for supporting the differential A slides in a direction substantially at right angles to the first slide 13. It is installed on the assembly table 10 as much as possible. Since there are two sets of drive shafts C for the left and right wheels, two second slides 15 are installed, but in FIG. 1, only one is completely shown and the other is partially omitted. I am doing it. A third slide 16 is installed adjacent to the second slide 15 on the assembly table 10, and a support jig 17 for supporting the axle D is provided on the third slide 16. Since two rear wheels are required for one vehicle body, two axles D as well as drive shaft C are required.
It is necessary to assemble the third slide 16 and the second slide
Two are installed like 15 but only one is shown.

FIG. 2 (A) is a cross-sectional view corresponding to the line II-II in FIG. 1, and the second slide 15 is installed on the rail 18 fixed to the assembly table 10, whereby the second slide is provided. 15
Is designed to slide. The other first and third slides 13 and 16 have substantially the same structure.
