Abstract

PURPOSE:To prevent misassembly and improve workability by operating the first or second positioning holding means at the prescribed peripheral position of a rotary table from the outside, and changing over guide pins according to a vehicle model. CONSTITUTION:When the first positioning holding mean 35 is changed over to operate at the prescribed peripheral position of a rotary table 21 from the outside, horizontal change-over levers 26a and 26b move sidewards and symmetrically in a horizontal direction around their pivotally installed parts, and guide pins 34 move horizontally along slots 33 of a vertical change-over lever 32 to change over and hold the guide pins 34 at the prescribed horizontal position. Also, when the second positioning holding means is changed over to operate at the prescribed peripheral position of the rotary table 21 from the outside, the vertical change-over lever 32 moves vertically to change over and hold the guide pins 34 at the prescribed position in a vertical direction. It is thus possible to prevent misassembly of a brake assembly and so forth for a steering arm positively only by changing over the guide pins according to a vehicle model.

) rotates clockwise around the pivot (67). Due to this rotation (66), the push-down member (63) moves downward along the push-up bar (60), and the horizontal engagement plate ( 54) Side edge of the center of the upper surface (L14 a 1t (54b))
63) engaging pieces (63c) (63c collide with each other,
Push down the horizontal engagement plate (54).

Then, the second sphere (55) separates from the lower annular groove (53b), the vertical switching shaft (53) moves axially downward, and the vertical clear image lever (32) moves downward in a horizontal position. . As the vertical switching lever (32) moves downward, each guide pin (34) moves downward, and the vertical switching shaft (5) moves downward.
3) Upper ring! When the second sphere (55) is inserted into the slot (53a), each guide pin (34) is inserted into the slot A of the elongated hole (33), as shown in Figures 3 and 4).
held at the lower end of the position. After that, press the cylinder (
The push loft (70) of the pivot lever (64) retracts and the pivot lever (6
6) rotates counterclockwise around the pivot (67), and the push-down member (63) returns to its original position at the rising end. When each guide pin (34) is held at the lower end, the rotary table (
21) rotates intermittently, and the first and second stations (a
) Paired mounting jig (22a) moved to (b)
(22b) Paired knuckle arms (la) on top

After being positioned in step 24), the brake assembly (8) is assembled with brake shoes, etc. by appropriate means.
are fitted into the cylindrical portions (2) of the pair of knuckle arms (la) and (lb) and placed on the collar portions (3). At this time, each guide pin (34) is held at the lower end, so the brake assembly (8) and the guide pin (34) do not move dryly, and the brake assembly (8) protrudes from the back. The provided protrusions (not shown) are fitted into the positioning jigs (25a) (25b) and positioned, and the knuckle arms (ia) (l
b) Each mounting hole (7) and brake 7 assembly 8)
Each through hole (10) corresponds to the center center. After that,
Knuckle arm (ia) ': ib with the same requirements as above
) and brake assembly (8) are bolted and fixed and discharged from the joint (f) in Figure 6. The following steps are the same: ・Tighten and secure the brake 7, ・senfuri (3), and 4-wheel drive and 2-wheel drive disc covers (9a) (9b) to the 7-cru arms (ia) (Ib) with bolts.

Effects of the Invention According to the present invention, a brake assembly in which a brake shoe or the like is attached to a knuckle arm positioned and held on a jig on a rotary table, or a brake assembly for four-wheel drive and two-wheel drive Before assembling the disc cover: By simply switching the guide pins depending on the vehicle model, you can reliably prevent the brake assembly, etc. from being incorrectly assembled to the knuckle arm, and also prevent the disc cover, etc. from attaching to the knuckle arm. It becomes possible to position and match the mounting holes of both to match the characteristics, and it is possible to significantly improve work efficiency.
