Device for feeding and screwing threaded parts - comprises holder component which by holding threaded part at its front end is longitudinally movable and rotatable advance feed bar

摘要

The threaded part handled is a screw (1) with a head (2) and a shaft (3). A rotatable advance feed bar (4) which can move forwards and backwards is a reception head (5) with an aperture (6) in which the screw head locates. A permanent magnet (7) is incorporated to prevent the screw falling out. The advance feed bar is set in rotation by a compressed air-driven rotary drive (8), and connected to the drive is a slide component (9) which moves forwards and backwards along a guide rail (10). The guide rail is provided a swallow tail guide groove in which the slide component fits. A part feed tube (15) is so arranged that it runs at an acute angle to the feed direction of the advance feed bar. USE - To feed forward screws and nut, and screw them into position.
