木工雕铣用它扇风冷自动换刀电主轴
摘要：
本发明涉及电主轴技术领域，尤其是一种木工雕铣用它扇风冷自动换刀电主轴。其包括机壳，设在机壳内的转子轴、定子部件和转子部件，以及分别设在转子轴两端的前轴承和后轴承，所述机壳为一体的方形且带有风道，所述机壳两端设有刀柄和独立风扇，所述独立风扇为七叶风叶，所述转子轴上设有自动换刀机构、汽缸和自动换刀机构的检测装置，所述机壳的前端设有密封盖。本发明大大地提高了电主轴的散热效果，扩大了电主轴的使用范围，且延长了轴承的使用寿命。
摘要（英）：

The invention relates to the electric spindle technology field, and especially relating to a fan air-cooled automatic tool change electric spindle used for carpentry carving and milling. The fan air-cooled automatic tool change electric spindle comprises a shell which is provided with a rotor shaft, a stator part and a rotor part, and a front bearing and a rear bearing which are provided at two ends of the rotor shaft. The shell is a one-body cuboid and has a wind channel. Two ends of the shell are provided with a tool shank and an independent fan. The independent fan has seven fan blades. The rotor shaft is provided with an automatic tool changer, a cylinder and a detection apparatus of the automatic tool changer. A front end of the shell is provided with a seal cover. According to the invention, a heat radiation effect of the electric spindle is substantially raised, a usage scope of the electric spindle is enlarged, and a service life of the bearing is prolonged.
