c) (63c) abuts and pushes down the horizontal engagement plate (54). Then, the second sphere (55) separates from the lower annular groove (53b), the vertical switching shaft (53) moves downward in the axial direction, and the vertical switching lever (32) moves downward in a horizontal posture. When the vertical switching lever (32) moves downward, each guide pin (34) moves downward, and when the second sphere (55) fits into the upper annular groove (53a) of the vertical switching shaft (53), As shown in FIGS. 3 and 4, each guide pin (34) is held at the lower end of the elongated hole (33) at the position A. Thereafter, the pressing rod (70) of the pressing cylinder (64) is retracted, and the rotating lever (66) rotates counterclockwise about the pivot (67), and the pressing member (63) is moved to the rising end. Return to the original position. When each guide pin (34) is held at the lower end, the turntable (2
1) rotates intermittently and the first and second stations (a)
The paired knuckle arms (1a) and (1b) are supplied and mounted on the paired mounting jigs (22a) and (22b) moved to (b), and are positioned by the positioning jigs (23) and (24). Then, by appropriate means, the knuckle arm (1a) (1
b) is fitted into each of the cylindrical portions (2) and placed on the flange portion (3). At this time, since each guide pin (34) is held at the lower end, the brake assembly (8) and the guide pin (34) do not interfere with each other, and the brake assembly (8) is projected from the rear surface. The protruding pieces (not shown) fit into the positioning jigs (25a) (25b) and are positioned, and the mounting holes (7) of the knuckle arms (1a) (1b) and the through holes (7) of the brake assembly (8). 10) coincides concentrically. Thereafter, the knuckle arms (1a) (1b) and the brake assembly (8) are bolted and fixed in the same manner as described above, and are discharged from the station (f) of FIG. The knuckle arms (1a) and (1b) follow the same procedure,
The brake assembly (8) and the four-wheel drive and two-wheel drive disk covers (9a) (9b) are bolted and fixed.

〔The invention's effect〕

According to the present invention, when a knuckle arm positioned and held on a jig on a rotary table is mounted with a brake assembly equipped with a brake shoe or the like, or a disk cover for four-wheel drive and two-wheel drive, By simply switching the guide pins according to the vehicle model, erroneous assembly of the brake assembly etc. to the knuckle arm can be reliably prevented. It is possible to make them coincide with each other, and it is possible to greatly improve workability.

Claims (1)

(57) [Claims] 1. A rotary table which is installed so as to be intermittently rotatable and has an even number of jigs arranged at equal circumferential positions so as to form a pair with two adjacent jigs. A plurality of pairs of horizontal switches that are arranged so as to be symmetrically rotatable in the horizontal direction about each pair of jigs at equal circumferential positions, and that the tip ends are butt-connected symmetrically. A lever and a pair of jigs on the rotary table are disposed so as to be vertically movable in a horizontal posture, and a plurality of long holes are respectively formed at both end portions facing each base end portion of the horizontal switching lever. The vertical switching lever and each of the long holes of the vertical switching lever are slidably penetrated through the long holes and are held upright by the vertical switching lever, and a part thereof is slidable in the vertical direction by the horizontal switching lever. Rotate between the plurality of penetrated guide pins and each of the above jigs. A switch is provided on the periphery of the table so as to be capable of switching operation from outside, and presses and pulls the tip of the horizontal switching lever to position and hold the guide pin at a predetermined horizontal position along the elongated hole of the vertical switching lever. A positioning and holding means, and a second rotary table which is provided between the jigs so as to be switchable from the outside, and which presses and pulls a vertical switching lever to position and hold the guide pin at a predetermined position in the vertical direction.
