为了提高铰孔质量和效率,我们设计了摩擦进给铰孔工具。经使用,效果良好。尤其是铰削大于φ30孔时,在保证质量的情况下,大大减轻了劳动强度。摩擦进给铰孔工具结构见附图。它由铰刀1、定位套2、支承调整螺钉3(三件)、支承板4等组成。加工时,按图装夹在工件上,用支承螺钉3将拉丝9调整至平行于工件孔的轴线,并用顶丝10适当顶紧摩擦丝母8,然后用扳手扳动铰刀1的方柄,此时铰刀开始进给,直至铰完为止。铰刀应设计两把,即粗精铰刀各一把。粗铰刀铰孔时应留有适当余量,精铰刀按标准铰刀方法设计。粗铰刀与一般铰刀不同的是切入端有与拉丝9相配的丝孔。该工具工作原理如下:当扳动铰刀时,摩擦丝母
In order to improve the reaming quality and efficiency, we designed a friction feed reaming tool. After use, the effect is good. Especially when reaming is larger than φ30 hole, labor intensity is greatly reduced with the guarantee of quality. Friction feed reaming tool structure shown in the drawings. It consists of reamer 1, positioning sleeve 2, the support adjustment screw 3 (three), the support plate 4 and other components. Processing, according to the map installed in the workpiece, with the support screw 3 will be drawn to 9 parallel to the axis of the workpiece hole, and with top wire 10 appropriate top tight friction nut 8, and then use the wrench to pull the handle 1 reamers , Then reamer start feeding, until the hinge finished. Reamer should be designed two, that is, a rough fine reamers. Rough reamer reaming holes should be left at an appropriate margin, fine reamer according to the standard reamer design. Rough reamer and general reamer is cut into the end of the wire with 9 matching wire hole. The tool works as follows: When pulling the reamer, rub the nut
