具有刀具交换装置的电主轴
摘要：
一种电主轴装置（100）包括：至少一个电主轴（2），围绕垂直轴线X‑X′延伸；所述电主轴（2）包括一个马达、一个用于传送运动的功能上与所述马达相关联的旋转轴杆，以及一个用于刀具固持器（3）的接合部分（6），可通过所述轴杆（39）旋转地致动的刀具（40）安装在刀具固持器中；所述刀具（40）被所述轴杆直接致动；至少一个刀具固持器支撑元件（5），包括至少两个刀具固持器（3）；每一刀具固持器沿垂直轴线延伸。所述刀具固持器支撑元件（5）可旋转地安装以便进行旋转，用于使得每一刀具固持器（3）与所述接合部分（6）对准。所述装置进一步包括至少一个用于旋转所述刀具固持器支撑元件（5）的装置。
摘要（英）：

Electrospindle device (100) including: at least one electrospindle (2) extending about a vertical axis X-X′; the electrospindle (2) including a motor, a rotating shaft for transmitting the motion, functionally associated with the motor, and an engagement portion (6) for a toolholder (3) in which a tool (40) rotatably actuated by the shaft (39) is mounted; the tool (40) being actuated directly by the shaft; at least one toolholder support element (5) including at least two toolholders (3); each toolholder extending along a vertical axis; e toolholder support element (5) is rotatably mounted so as to rotate for bringing each toolholder (3) into alignment with the engagement portion (6). The device further includes at least one device for rotating the toolholder support element (5).
