Abstract

En seksstavers leddsammenstillingsmekanisme for tilpasning til konfigurasjonen av en tilpasningsoverflate med et sentralledd (10) avgrenset av et verktøylegeme og et sadelledd (12) i avstand fra sentralleddet (10) og bevegelig for tilpasning med tilpasningsoverflaten (T). Et par frontledd som hvert har dreieforbindelse med respektive ender av sadelleddet (12) og som har lineær bevegelig dreieforbindelse med sentralleddet (10) for å tillate vinkelmessige og avstandsendringer av sadelleddet (12) i forhold til sentralleddet (10). Et par sentraliseringsledd (4, 6) er lokalisert mellom frontleddene (2, 8) og har dreieforbindelser med sadelleddet (12) og dreieforbindelser med sentralleddet (10). En av dreieforbindelsene er lineært bevegelig på sentralleddet. Én av disse dreieforbindelser (22) er lineært bevegelig på sentralleddet (10).For trekkverktøy, når tilpasningsoverflaten er et borehull eller ett foringsrør, rager et flertall av seksstavers leddsammenstillinger radialt ut fra et verktøylegeme for å tilpasse overflatetrekket til tilpasningsoverflaten.
