为改进ZQ-250减速机机体(图1)上的φ90、φ150内孔环槽的加工工艺,提高工效,我们设计制造了一种结构简单的组合式环槽切割工具(图2),在铣床上使用效果很好。结构原理及其使用工具体1一端为7∶24锥体,安装在卧式铣床的主轴锥孔内,尾端以拉杆紧固;另一端制成12°30′斜面与切刀6刀体相配。工具体的φ90、φ150凸肩与工件孔应保持0.05mm左右的间隙。切槽时,先将工件插入工件孔内,套筒2端面稍稍压紧工件孔端面;然后开动机床,则工具由机床主轴带动一起旋转,同时作轴向进给。旋转运动的扭矩,由工具体1和导向定
In order to improve the machining process of the φ90, φ150 inner ring groove on the ZQ-250 reducer body (Figure 1) and improve the work efficiency, we designed and manufactured a simple combined ring groove cutting tool (Figure 2) On the use of good results. Structural principle and its use Tool body 1 end 7:24 cone, installed in the spindle horizontal spindle milling machine, the tail end of the tie rod fastening; the other end made of 12 ° 30 ’incline and knife 6 knife body match . Tool body φ90, φ150 shoulder and the workpiece hole should be maintained about 0.05mm gap. When grooving, the workpiece is inserted into the workpiece hole first, and the end face of the sleeve 2 is slightly pressed against the end face of the workpiece hole; then the machine tool is started, and the tool is rotated together with the spindle of the machine tool for axial feeding at the same time. Torque of rotary motion, fixed by the tool body 1 and guide
