由钻孔、攻丝、底孔检测、装置丝套、冲断装置柄、罗纹检测六个首要步骤构成，见右图

The assembly instructions of the thread insertIt consists of drilling、tapping、bottom detect、installation of thread insert and break-offtool, mainly, thread detect、the six assembly instructions follows:

1、钻孔  按表中d0的尺寸选用适合钻头，刃磨精确，钻孔后孔口倒角不易跨越0.4P深度，倒角过大倒霉于丝套的装置，最好为120°倒角。

1、Drilling:

The taper should be selected suitably from the dimension of do in the table and be sharpened accurately The chamfer is inappropriate to exceed the depth of 0.4p after tapping. the best chamfer is 120°, which makes against setting of thread insert if it is too big.

2、攻丝  用响应规格的丝套公用丝锥攻丝，用户可按照所需内螺孔的精度，恰当挑选攻丝体例和光滑体例，盲孔攻丝时要用力恰当，以避免丝锥折断，攻丝后应清算清洁罗纹孔，避免螺孔与丝套间有杂物。

2、Tapping:

The special screw tap corresponding to the thread insert is selected to use (using lubricant oil or grease for this operation) when the through hole is tapped, the force should be appropriate to prevent taper rupturing. After tapping the tape hole should be cleared.

3、底孔检测 攻丝后把底孔碎削清算清洁，在钢丝螺套装置之前用底孔塞规检测底孔通止规环境。

3、Bottom detect:

Clean up bottom clastic after tapping, detected the pass and stop instrumeat of bottom by bottom plug before the installation.

4、装置丝套  在普通环境下利用手动装置扳手装置丝套，将丝套放入套筒槽口内，丝套装置柄朝下，芯轴穿过丝套卡住装置柄，拧入导套处，瞄准基体螺孔，顺时针动弹芯轴。应注重不要在丝套装置柄上施加较大的轴向力，以防跳扣或装置柄折断。

4、Installation of thread insert:

Insert the tool in the dilled hole lower than the

thread insert into the tapping pressure.

5、冲断装置柄  通孔时，要将丝套装置柄冲断，普通用冲断器瞄准装置柄，用200g摆布的鎯头猛击一下便可去除，对18×2.5以上的粗牙丝套和14×1.25以上的细牙丝套，用尖嘴钳高低曲折装置柄便可去除。

5、Break-offtool:

Break the tail off using the break-off tool in order to use the whole length of the tapping

6、罗纹检测  装置钢丝螺套以后，用罗纹塞规检测通止规环境。

6、Ｔhread detect:

After installing the screw sets, detected the  pass and stop instrument by thread plug guge.

7、 取钢丝螺套：在装置进程中呈现题目或因为钢丝螺套利用时候太久须要掏出丝套，该当使用带有刃的卸套东西瞄准螺套端口，用鎯头猛打一下，用手加力按下手柄反罗纹扭转便可加入钢丝螺套。
