Composite tool for a milling drum, milling tool holder and milling drum

摘要

The present invention relates to a composite tool comprising at least two milling tool holders, to a milling tool holder for such a composite tool and to a milling drum equipped with such milling tool holders. According to the present invention, a milling tool holder is utilized for supporting a tool replacement device during tool replacement of the milling tool in the milling tool holder that precedes it in the peripheral direction. To this end, according to the present invention, a supporting area is provided on the base element of the milling tool holder, which supporting area provides appropriate stabilized guidance for the tool replacement device.

主权项

1. A composite tool for a milling drum comprising:
at least one forward milling tool holder, as regarded in the direction of rotation (U) of said milling drum, and at least one rearward milling tool holder disposed directly behind said forward milling tool holder, as regarded in the direction of rotation (U) of said milling drum, and offset therefrom in the axial direction of the axis of rotation (R) of the milling drum, wherein each of said milling tool holders is adapted to accommodate a milling tool, each of the milling tool holders comprising: a base element having a bottom surface for attachment to a supporting barrel of a milling drum and a top surface disposed opposite to said bottom surface; a holding member projecting upwardly from the top surface of the base element and comprising a continuous receiving channel for the accommodation of said milling tool, which receiving channel extends through said holding member from a front side opening on the forward side to a rear side opening on the rearward side, wherein at least on the base element of said rearward milling tool holder, as regarded in the direction of tool advance, there is provided, adjacent to said holding member, a supporting area for a milling tool replacement device, which supporting area opens out to said forward milling tool holder and comprises a device configured to provide stabilized guidance of said milling tool replacement device from the supporting area of said rearward milling tool holder toward the rear side opening of the receiving channel of said forward milling tool holder and to prevent movement of said milling tool replacement device in opposite axial directions relative to the supporting area.
