Abstract
692,008. Turrets. BECHLER, A. Oct. 3, 1951 [Oct. 26, 1950], No. 22990/51. Class 83 (iii), A tool-turret for lathes of the kind comprising an indexible body carrying axially movable toolholders, some of which are rotated, is characterized in that the toolholders are supported in the bores of journals, or of bosses associated with gear wheels, which are interchangeable, and that means are provided for permitting or preventing rotation of a tool-holder in the body or turret without interfering with the axial displacement of the tool-holder. The turret body comprises a hollow body portion 8, Fig. 1, and a flange 13 with a hollow shaft extension 7 which are separable to interchange the parts carried within and which may be bolted together in proper alignment by screws 12. The turret is supported in a rear bearing bracket 6 and at the front by an adjustable bracket 9 with a tapered bore. The assembly is adjustable towards and away from the lathe spindle 5 along a slideway 2. Handles 32 are provided for rotating the turret and a hand-operated lever 33, Fig. 2, with an end-piece 34 for engaging notches in the periphery of the flange 13 enables the turret to be indexed. These operations and the axial feed of the tools may be effected automatically by cams, if required. The tool-spindles 26a-26f, Fig. 2, are arranged around the axis of the turret and supported in bores in the front end of the hollow body and by journals 14, Fig. 1, in the rear plate 7, if the spindles are not required to rotate. Gear wheels 23 with integral bosses are interchangeable with the journal members and are used if the spindles are required to rotate. The bosses are provided with driving keys 29 which engage grooves 30 in the spindles. Adjustable tappets 37 are provided on the ends of the spindles adapted to be contacted, in the working position, by the end of a cranked hand-lever 36 for feeding a tool-spindle, the lever contacts a stop 39 to limit the feed movement, springs 40 return the spindles after a working operation. Set screws 31 in the front of the turret body are tightened to engage the groove in the tool-spindle when it is not required to rotate. The gear-wheels 23 engage a central gear-wheel 20 on a driving spindle 18, which is supported in the hollow shaft 7, and is driven by a pulley 19 at its other end. The gears 23 may be arranged to give a forward rotation to the tool-spindles by using an idler gear on an adjacent spindle.
