PARTS ASSEMBLER

PURPOSE:To automate assembling of parts of pack and fastening of nuts by providing a machine frame, slide unit and fastening mechanism to a parts assembler for synthetic fiber string pack then rotating the fastening mechanism with high or low torque. CONSTITUTION:A pack body 40 is fed to the assembling position of table 2 to project the rod 5' of cylinder 5 thus to lift the receiving table 4 through a hole in pack 40. Upon supply of specific parts, the receiving table 4 is lowered from the table 2 to insert the parts into the pack 40. Upon supply of lock nut 44 onto the upper face of pack 40, the rod 8' of cylinder 8 is projected to lower a slide unit 6 and stop at the position where the click 11 of fastening tool 10 will contact with the nut 44. Under this state, a drive system 16 is operated to rotate the rotary shaft 14 with low torque thus to engage the click 11 with the nut 44 and to tighten the nut 44 over the pack 40. Thereafter, a stopper 21 is engaged with a hole for fixing the slide unit 6 to rotate a fastening tool 10 through drive system 16 with high torque thus to tighten furthermore.
