FIELD: machine engineering, namely mechanical strippers. ^ SUBSTANCE: stripper includes traverse bar with grips, screw having two outer threads with different pitches; main detachable sleeve mounted by thread whose pitch is less than that of said screw; additional threaded sleeve mounted by second thread of said screw; holder embracing both sleeves, fixed relative to them in angular direction and resting by its inner shoulder upon end of main sleeve. Inner shoulder is formed on one end of holder; other open end of holder is arranged in through opening of traverse bar and it is rigidly joined with said bar. Threads of powerful screw have similar sign; additional sleeve has outer flange spaced from open end of holder by interval determined according to relation K = B1(H2/H1 - 1), where K - interval between outer flange of additional sleeve and open end of holder; B1 - displacement (caused by main sleeve) of part stripped by means of stripper; H2 - thread pitch of additional sleeve; H1 - thread pitch of main sleeve. Sleeves are mutually spaced by interval T exceeding value of mutual convergence of sleeves. ^ EFFECT: simplified usage of stripper. ^ 1 dwg |
