在车床加工零部件中,遇到镗削如外孔小、里孔大的葫芦形孔时,用通用镗杆调整不便,操作困难。我们采用了图1所示之刀排,达到了操作较方便提高效率的目的。简单介绍如下。一、结构图1镗葫芦孔刀杆中,镗杆主轴4的前部有高精度长孔与心轴5紧密滑配,并有与刀体滑动配合的方孔。刀体6可在方孔中上下移动,后部有腰形槽。螺母1内圆中部开圆弧槽,插入直销3,转动螺母1,带动直销3(前后移动,不转动),使心轴5前后移动;键
In the lathe processing parts, such as boring encountered outside the hole, the hole in the gourd-shaped hole, the general boring bar to adjust the inconvenience, difficult operation. We use the knife shown in Figure 1, to achieve more convenient operation to improve efficiency. Brief introduction is as follows. First, the structure Figure 1 boring gourd hole Arbor, boring bar spindle 4 in front of a high-precision long hole with the mandrel 5 with a smooth slide, and the body with a sliding square hole. Knife body 6 can move up and down in the square hole, the back of the waist-shaped groove. Nut 1 inner circle circular arc groove, insert the direct sales 3, turn the nut 1, drive the direct sales 3 (before and after the move, do not rotate), so that the spindle 5 before and after the move; key
