Abstract

747,037. Honing. ROHR, A. Jan. 19, 1954 [Jan. 22, 1953; Oct. 26, 1953], No. 1616/54. Class 60 A honing tool, Figs. 1 and 2, comprises a body the front part 2 of which is provided with grooves 27 in which are arranged radially movable shoes 10 carrying honing stones 11 and collapsed by garter springs 12. The rear part 4 of the body is secured to the front part 2 by an adapter sleeve 3, and is coupled by a pin 14 to the head 15 of the drive element. The shoes 10 bear against cams 19 on the front part 18 of an adjusting shaft 1. A nut 9, having holes 26 to receive a wrench; is mounted on the threaded end 22 of the shaft 1. The axial movement of the nut 9 resulting from its rotation is transmitted through a thrust ball bearing 7 to a sleeve 6 formed as a nut to engage a coarse thread 23 on the adapter sleeve 3 so that the axial movement of the sleeve 6 causes its rotation and thus, through key 8, rotation of the shaft 1, so that the cams 19 adjust the stones 11. Axial movement of the sleeve 6 is limited by a nut 5 on a threaded part 24 of the adapter sleeve 3. The adjusting nut 9 and limit nut 5 can be manipulated through slots 28 in the part 4; a scale may be provided on the limit nut 5. In a modification, Fig. 5, rotation of a nut 41 threaded on part 33 of the adjusting shaft 31 causes it to move axially, this movement being transmitted to a member 37 having oblique slots 40 engaged by pins 39 on the shank 45 of the tool body 46 so that the member 37 rotates and through a key 38 rotates the adjusting shaft 31. Axial movement of the sleeve 37 is limited by nuts 42, 43 on threaded part 44 of the tool body; the sleeve 37 carries a scale.
