Abstract:
A method of manufacturing an end assembly of an engine oil cooler with an apparatus that includes (i) a compression member having a roller surface defined thereon, (ii) a motor operatively coupled to said compression member such that said motor can rotate said compression member around a central axis of rotation, and (iii) a drive cam for urging said compression member outwardly from said central axis of rotation, wherein said end assembly includes (i) an outer component which defines a first lumen and (ii) an inner component which defines a second lumen, comprising the steps of:creating a channel in an interior surface of said outer component;positioning said inner component within said first lumen;locating said compression member within said first lumen and said second lumen such that (i) said compression member is completely contained within said first lumen and said second lumen and (ii) said roller surface is in contact with said inner component and aligned with said channel;rotating said compression member around said central axis of rotation with said motor; andmoving said drive cam so as to cause said roller surface of said compression member to be urged against said inner component thereby causing a portion of said inner component to deform and move into said channel of said outer component thereby securing said inner component to said outer component.
