ADJUSTMENT OF WORK PALLETS FOR VEHICLE BODY ASSEMBLY LINES

摘要

Vehicle body assembly line apparatus includes a plurality of work pallets (14) having locators (18) with locator members (36) that are adjustable by a grab member (40) on each at a remote location below a vertical rest surface (37) mounted on each locator member. An adjusting station (16) provides either automatic adjustment of the adjustable locators (18) by one or more robots (52) or manual adjustment of the adjustable locators (18). A sensor (58) senses the location of a positioning target (56) on each locator member (36) at a known location from its vertical rest surface (37) and any locator pin (38) mounted thereon and generates a deviation signal when the positioning is not within a design tolerance. A control (60) readjusts the appropriate locator (18) as necessary to the design tolerance range.
