Drum-type tool magazine adaptive to multi-axis machining center

A drum-type tool magazine adaptive to a multi-axis machining center such that the drum-type tool magazine is configured for allowing the machining center to use at least one spindle to directly take and replace tool holders holding machining tools from and to, respectively, the drum-type tool magazine, the drum-type tool magazine comprising:

• a driving member;
• a drum, being centrally provided with a rotating shaft and having a columnar periphery along which periphery a plurality of separated mounts are arranged circularly, wherein the driving member is connected to and thereby drives the drum to rotate about a rotation axis, and the rotating shaft has two ends thereof, wherein each of the two ends is provided with a respective fixing seat for engaging with the machining center, and wherein the drum has two round tool discs that have equal outer diameters and are fixedly connected to the rotating shaft, so that the periphery is defined by circumferences of the two tool discs connected along an axial direction of the rotation axis, and the two tool discs are located on the rotating shaft about the rotation axis, wherein the tool mounts are each fixed to the outside of the two tool discs for rotation with the two tool discs about the rotation axis;
• and
• a plurality of tool clamps for clamping the tool holders, the tool clamps being arranged abreast along the axial direction of the rotation axis and being mounted on the mounts such that plural ones of the tool clamps are mounted on each of the mounts, wherein the tool clamps each have a respective two tool-clamping jaws, wherein each pair of the tool-clamping jaws opens and closes in a direction along the rotation axis, wherein a respective longitudinal axis of each of the tool-clamping jaws is parallel to a tangential direction that is tangential to the periphery, and each pair of the tool-clamping jaws is configured to hold a respective tool holder such that the machining tool held by the corresponding tool holder is configured with a respective longitudinal axis of the corresponding machining tool being non-radial and non-axial relative to the rotation axis and with the respective longitudinal axis of the corresponding machining tool being parallel to a tangential direction that is tangential to the periphery.
