Abstract

1,192,505. Machining long holes. TIEFBOHR-TECHNIK G.m.b.H. & CO. 27 Sept., 1968 [7 Oct., 1967], No. 45899/68. Heading B3C. In a honing, reaming or deep boring machine the tool 4, Fig. 1, is fed towards the workpiece 2 by members 5 and 6, by having one member clamp the bar and move in the direction of arrow 7, whilst the other member unclamps the bar, and is retracted along the bar in the direction of arrow 8. The clamping members 5, 6 are rotatably supported in carriages 12, 13, Fig. 2, the carriages being guided for sliding movement on rods 10, 11. Each of the members 5, 6 comprises a collet 16, operated by a piston 17, actuated by an hydraulic slide valve 18 or 19. The carriages are moved along rods 10, 11 by cams 24, 25, carried on a shaft 23, rotated by a worm and wheel 29, and the members 5, 6 are rotated by a pulley 28, through gears 20-22. Boring bar 4 is retracted at a fast rate by rollers 30, 31, Fig. 4, having grooves shaped to conform with the shape of bar 4. In a modification, the bar is retracted by a geared motor (34), and pulley (33), Fig. 7 (not shown). In a further modification, the retraction is produced by a weight (35), Fig. 8 (not shown). In a still further modification, the boring bar is retracted at a fast rate by speeding up the shaft 23 in a reverse direction by the provision of a pole changeable drive motor, and having intermediate members 36, 37, Fig. 9, connecting cams 24, 25 with carriages 12, 13. Hydraulic or pneumatic elements may be used in place of a mechanical forward feed and retraction.
