VAERKTOEJSHOLDER TIL BORE- OG MEJSELVAERKTOEJER |
摘要 |
A tool holder for drilling and chiselling tools includes a receiving sleeve forming a bore with a conically shaped section for receiving a conically shaped shank on a drilling or chiselling tool. Shoulders extending in the axial direction of the sleeve are formed on the surface of the conically shaped section for interengagement with grooves in the drilling or chiselling tool shank so that the sleeve can rotate the tool. Locking elements in the form of axially elongated pins are mounted in the receiving sleeve so that the pins extend transversely of the sleeve axis and tangentially of the conically shaped bore section. The pins are spring biased toward the bore section and are displaceable generally radially relative to the bore. The pins are arranged to seat within an annular groove in the shank of the tool. |
