Title: Tapping tool holder with torque overload release coupling
IPC: B23G1/46
Filed: 1976-02-26
Abstract: 1501785 Positive clutches O BILZ [trading as OTTO BILZ WERKZEUGFABRIK] 26 Feb 1976 [14 March 1975] 07602/76 Heading F2C [Also in Division B3] An overload-torque-releasing device in the form of a tap holding chuck or, as shown, a tap holding attachment for a chuck comprises an input drive sleeve 13 driven by the machine or chuck through dogs 16 and an output driveshaft 12 which is retained axially in the machine or chuck by engagement of groove 17 and has means-socket 15 and clamping bush 14, for holding a tap 11. The sleeve and shaft are rotatably coupled by means of one or more balls 20 located in respective inclined slots 23 in the end of sleeve 13 and engaged in pockets in the form of blind bores or, as shown, depressions 25 in shaft 12. The sleeve 13 is enclosed by a longer sleeve which also encloses a spring- loaded thrust-ring 29 for urging the balls into the coupling position-the right-hand side of Fig. 1 and Figs. 3a, 4 and 5. In use, the balls are retained by the ring 29, which may be axially guided, centred, and non-rotatably mounted on shaft 12 by balls 40, and abut contact faces 54, Figs. 3a and 4, on slot sides 50 although these need not be provided. At the torque limit, set by spring adjustment ring 31 screwed into sleeve 26 and locked by circumferential spring 35, 36, the balls ride out of the pockets against the spring action, along frustoconical surface 60 of thrust ring 29 and fully into inclined slots 23 to finally roll circumferentially along annular groove 28 in sleeve 26 and on planar surface 61 on the end of ring 29, Fig. 5. The balls do not fall back into the pockets and this is due to the inclination of the slots and the surface 61 of ring 29 and so the device remains uncoupled until the sleeve 13 is driven in reverse whereupon the balls return. Torque limitation does not occur on reverse rotation. The side walls of the slots 23 may be parallel to the axis 21, Fig. 2, or may be inclined thereto-not shown.
