AUTOMATIC FEEDING AND CLAMPING SYSTEM FOR BOLT AND AUTOMATIC FEEDING AND FITTING-UP DEVICE THEREOF

摘要

PURPOSE:To promote automation for clamping bolts by feeding each bolthole of a work with a bolt in order through a uniaxial robot and, after its fitting up, clamping respective bolts simultaneously with each clamper. CONSTITUTION:Each of automatic bolt feeding and fitting-up devices 2, 3 are installed in both upper and side parts of a belt conveyor 1 and each of automatic bolt clampers 4, 5 in both upper and side positions at the downstream side, respectively. Each of these automatic bolt feeding and fitting-up devices 2, 3 is attached to arms 10a, 11a of uniaxial robots 10, 11, and the automatic bolt feeding and fitting-up device 2 feeds, for example, flange bolt to an oil pan 58 being attached to an engine body 59 and its fitting-up takes place, while the automatic bolt feeding and fitting-up device 3 feeds a bolt to a front end of the engine body 59 and its fitting-up takes place as well. The bolt clampers 4, 5 clamp all bolts temporarily tightened to a frame simultaneously with the specified clamping torque.
