利用丝锥攻内螺纹(攻丝)和用手铰制外螺纹(套扣)都是钳工操作中最常见的作业.一般作业用目测,凭经验,或用角尺检查.当发现工具与工作件中心编斜时,必须强制进行调整,为提高手工攻丝和套扣的质量和生产率,防止在切削过程中工具与工件的中偏斜,导致工件报废,丝锥拆断或扳手扭裂造成的损失.本文介绍两种加工方法.1 攻丝加工一块钻有不同孔径的丝锥导板(图1)攻丝时将其放在钻有螺纹底孔的工件表面.将相应的孔径对准工件上欲攻丝的底孔,丝锥垂直导入工作的底孔,板动铰手使丝锥切削部分进入工件2～3牙后取下该导
Tap tapping (tapping) and hand reaming (threading) are the most common operations for fitter operations. Visual inspection of the general operation, by experience, or the use of square ruler. When the tool and the work piece center In case of skewing, the adjustment must be forcibly made. In order to improve the quality and productivity of manual tapping and buckle, prevent the skew between the tool and the workpiece during the cutting process, resulting in the scrap of the workpiece, the torn screw disassembly or the wrench twisting. This article describes two kinds of processing methods .1 tapping processing a drill with a different diameter of the tap guide (Figure 1) tapping when it is placed on the surface of the workpiece with a threaded bottom hole. The corresponding aperture on the workpiece to be tapping Of the bottom hole, the tap into the bottom of the vertical work, the plate hinges the cutting part of the tap into the workpiece 2 ~ 3 teeth removed after the guide
