COUPLING PART FOR ROTARY TOOL AND ROTARY TOOL INCLUDING SAME |
摘要 |
A coupling part structured to engage with a complementary coupling part for interchangeably fastening a cutting head to a carrier of a rotary cutting tool. The coupling part includes a pair of coupling pins arranged opposite each other with respect to a central longitudinal axis and spaced apart from each other so as to form a receiving space structured to receive a central pin of the complementary coupling part. Each coupling pin includes a stop surface for transmitting a torque, a radially external outer surface, and a radially internal inner surface. At least one of the outer surface or inner surface is a clamping surface oriented in an obliquely inclined manner with respect to the central longitudinal axis for centering and clamping the coupling part. |

1. A coupling part structured to engage with a complementary coupling part for interchangeably fastening a cutting head to a carrier of a rotary cutting tool, the coupling part comprising a pair of coupling pins arranged opposite each other with respect to a central longitudinal axis and being spaced apart from each other so as to form a receiving space structured to receive a central pin of the complementary coupling part, wherein each coupling pin comprises:
a stop surface for transmitting a torque; a radially external outer surface; and a radially internal inner surface, wherein at least one of the outer surface or inner surface is a clamping surface oriented in an obliquely inclined manner with respect to the central longitudinal axis for centering and clamping the coupling part. |
