Bidirectional right-angle milling head mechanism

The utility model discloses a bidirectional right-angle milling head mechanism which comprises a spiral bevel gear I, a locking nut I, a bearing seat, an angular contact ball bearing, a shell, a labyrinth ring, a labyrinth cover, a transmission end face key, a milling head cutter mounting main shaft, a spiral bevel gear II, a tapered roller bearing and a locking nut II. The milling head spindle is reasonable in design, the two connectors I SO40 and Morse 40 are arranged in front of and behind the milling head spindle, tool installation can be achieved under the condition that a rotation angle is not needed, the structural form that only one end of a common right-angle head spindle can be used for tool installation is replaced, the working running state of the milling head is stable, and turning and milling machining efficiency is improved. 本实用新型公开了一种双向直角铣头机构，包括螺旋伞齿轮一、锁紧螺母一、轴承座、角接触球轴承、壳体、迷宫圈、迷宫盖、传动端面键、铣头装刀主轴、螺旋伞齿轮二、圆锥滚子轴承和锁紧螺母二。本实用新型设计合理，铣头装刀主轴前后设置两个接口I SO40和莫氏40，可以在不用回转角度的情况下实现装刀，替代了一般直角头主轴只能一端装刀的结构形式，且铣头工作运行
