METHOD AND DEVICE FOR FABRICATING PISTON ASSEMBLY

摘要

The invention is intended to permit automatic installation of pistons and shoes on a swash plate, for reducing in costs and improving the quality of a swash plate type compressor. A slide table 52 is provided which is movable in a direction perpendicular to the axis O of a rotating shaft 2. A plurality of pistons 4 to be assembled are disposed on the, slide table 52 in a manner parallel to one another. When the slide table 52 is advanced, the shoes 7 disposed within a notch 4a in each of the pistons 4 on the slide table 52 are raised to a substantially vertical position by means of a presser member 54 and the piston 4 is aligned with the peripheral edge of the awash plate. A pair of heads 50 and 51 for supporting the rotating shaft 2 are provided with a shaft support portion 55 for supporting the rotating shaft 2 thereon. A plurality of piston support portions 67 for supporting the pistons are provided around the shaft support portion at circumferential positions. The pistons on the slide table 52 are supported by the piston support portions 57 in their assembled positions on the peripheral edge of the swash plate. The piston support portions 67 are unitarily rotated a predetermined pitch in synchronous with advancement of the slide table. 46
