大螺距螺旋升角可调角度螺纹车刀设计

Design of Adjustable-Angle Thread Turning Tool of High-pitch Helix Angle

设计了一种能转动角度的刀杆机夹式刀片,在刀体的弧面上标有刻度,刀体能在夹紧套内转动,装入刀片后可按工件螺纹升角的大小调整刀体的转动角度,用于车削不同螺距和旋向的螺纹,既节省刀具材料又提高了工作效率。

A cutter rod clamping-type blade structure with a rotatable angle is designed,with scales on the curved surface of the cutter body. The cutter body is able to rotate in the clamping sleeve. After the blade is installed,the rotation angle of the cutter body can be adjusted based on the helix angle of the workpiece,the thread tool used for turning threads with different pitches and rotation directions,saving tool material and improving working efficiency.
