我厂设计了一种结构简单,容易调整的内孔割槽装置。它由刀具和刀尖、横向进刀机构、主轴错、夹具等四部份组成。其最大特点是“加工装置”处在工件孔中,没有纵向运动,仅有横向运动(走刀)。结构比较紧凑,工具的外壳可缩小,加工精度易于保证。它特别适合于较浅内孔或肓孔的加工。割槽刀具6借助于两只方头螺钉21,被夹紧在燕尾槽的刀体5上。刀具应缩进刀体10～12mm,以便
I plant designed a simple structure, easy to adjust the hole cut slot device. It consists of knives and tool tips, horizontal infeed, spindle error, fixture and other four parts. Its most important feature is the “processing device” in the workpiece hole, there is no vertical movement, only horizontal movement (take the knife). The structure is compact, the tool shell can be reduced, the processing accuracy is easy to guarantee. It is particularly suitable for shallow bore or countersink processing. The grooving tool 6 is clamped to the body 5 of the dovetail groove by means of two lag screws 21. Tool should be retracted into the body 10 ~ 12mm, so
