<p>PURPOSE:To have sure assembly by enlarging spaces between parts by utilization of vacuum and eliminating damages of the parts caused by one another. CONSTITUTION:Air source 4 is connected to No.1 ejector 1, which is mounted on a slide base 2, with a seletor valve 3 interposed, and a plastic attachment 5 is installed to this ejector with a piping 5' interposed. This plastic attachment 5 is made of a comparatively soft material, and if its opening part is put in contact with a plastic part 6 and air is fed to No.1 ejector 1 form the air source 4 through the selector valve 3, the air is exhausted from No.1 ejector 1 in the A direction, when the space 7 between th plastic attachment 5 and the part 6 will be depressurized by means of the ejector effect. Thereby the part 6 is attracted by the plastic attachment 5.</p> |
