FESTE FOR BORRHUVUDSVERKTYG

摘要

A holding device for a boring head tool and the tool itself are arranged so that the tool can be mounted from the rear of the boring head. The tool is mounted on a supporting member which has head parts provided with supporting faces and the holding device has rigid support surfaces for engaging the supporting faces of the tool. The support surfaces are directed towards the front of the holding device and the holding device also has passages extending from the rear to in front of the rigid support surfaces as to allow the passage therethrough of the head parts for assembly. The head parts are conveyed through the passages in rotated positions offset with respect to their position in the assembled state and then moved to an assembly position in which the contact surfaces of the tool are held against the rigid support surfaces of the holding device by fastening screws which engage in threaded bores of the head parts.
