CABLE CONNECTION STRUCTURE OF REVOLVING TYPE ROTARY TOOL HEAD

摘要

PROBLEM TO BE SOLVED: To propose a technical means compactly wiring a power cable of a built-in motor between a tool rest of a machine tool and a revolving type tool head mounted on the tool rest.SOLUTION: The power cable of a tool driving motor mounted on the revolving type tool head is relayed by a revolving connector and is reconnected to an electric cable of a type different from the power cable, and the electric cable is connected to a movable connector fixed to the tool rest mounted with the tool head and is further connected from the movable connector of the tool rest to a base supporting the tool rest through an electric cable whose bending radius is restricted by a Cableveyor (R). The revolving connector is supported by a protection member extending to a space of the tool rest formed on the side opposite to the tool head. The electric cable connecting the revolving connector and the movable connector fixed to the tool rest is a cable allowing twisting.
