一般箱体孔內的环槽,大多使用鏜床徑向进給机构加工。而設計如图所示的切槽工具,就可以在普通钻床上方便地进行加工,我厂經使用后,技术經济效果良好。推杆9受軸向力向右移动时,銅焊在斜面滑块6上的刀体5就沿着斜面徐徐伸出。切削扭矩由足够强度的肖子3傳递,直到肖子碰到壳体2的槽底时,环槽已加工到要求深度。卸除推杆上的軸向力后,借彈簧1的作用力使推杆左移,此时推杆斜面紧压支承螺釘7,这就使斜面滑块連刀体急速退进壳体。支承螺釘是被定位螺釘8鎖紧的。斜面角度a由工作物的槽深H及斜面滑块6的寬度L决定:a=are tg(H/L·K),K为斜面支承系数,取0.65～0.8。为保証滑块斜面与推杆斜面良好,磨損均匀,工作时移动平稳,則肖子与长槽、推杆外徑与壳体孔徑、斜面滑块与壳体均要求滑配合;直徑D与工作物孔徑紧
Ring hole in the general box hole, most of the use of radial boring machine feed institutions. The design shown in the slotting tools, you can easily drill on the ordinary processing, I plant after use, technical and economic results. When the push rod 9 is moved to the right by the axial force, the blade body 5 brazed on the inclined slider 6 slowly extends along the inclined surface. The cutting torque is transmitted by the Schoetter 3 of sufficient strength until the Schottberg meets the bottom of the housing 2, and the annular groove has been machined to the required depth. After removing the axial force on the push rod, the push rod is moved to the left by the force of the spring 1, and the inclined surface of the push rod is pressed against the support screw 7 at this moment, which causes the inclined slider to rapidly retract into the shell. The support screw is locked by the set screw 8. The bevel angle a is determined by the groove depth H of the work piece and the width L of the bevel slider 6: a = are tg (H / L · K), and K is the bevel support coefficient, taking 0.65-0.8. In order to ensure that the slope of the slider is good with the slope of the putter, the wear is uniform and the movement is stable when working, the outer diameter of the shank and the length of the slot, the outer diameter of the push rod and the aperture of the shell, Tight aperture
