由鉆孔、攻絲、底孔檢測(cè)、安裝絲套、沖斷安裝柄、螺紋檢測(cè)六個(gè)主要步驟組成，見右圖

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、鉆孔  按表中d0的尺寸選用合適鉆頭，刃磨準(zhǔn)確，鉆孔后孔口倒角不易超過0.4P深度，倒角過大不利于絲套的安裝，最好為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、攻絲  用相應(yīng)規(guī)格的絲套專用絲錐攻絲，用戶可根據(jù)所需內(nèi)螺孔的精度，適當(dāng)選擇攻絲方法和潤(rùn)滑方式，盲孔攻絲時(shí)要用力適當(dāng)，以防止絲錐折斷，攻絲后應(yīng)清理干凈螺紋孔，防止螺孔與絲套間有雜物。

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、底孔檢測(cè) 攻絲后把底孔碎削清理干凈，在鋼絲螺套安裝之前用底孔塞規(guī)檢測(cè)底孔通止規(guī)情況。

3、Bottom detect:

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

4、安裝絲套  在一般情況下應(yīng)用手動(dòng)安裝扳手安裝絲套，將絲套放入套筒槽口內(nèi)，絲套安裝柄朝下，芯軸穿過絲套卡住安裝柄，擰入導(dǎo)套處，對(duì)準(zhǔn)基體螺孔，順時(shí)針轉(zhuǎn)動(dòng)芯軸。應(yīng)注意不要在絲套安裝柄上施加較大的軸向力，以防跳扣或安裝柄折斷。

4、Installation of thread insert:

Insert the tool in the dilled hole lower than the

thread insert into the tapping pressure.

5、沖斷安裝柄  通孔時(shí)，要將絲套安裝柄沖斷，一般用沖斷器對(duì)準(zhǔn)安裝柄，用200g左右的榔頭猛擊一下即可去除，對(duì)于18×2.5以上的粗牙絲套和14×1.25以上的細(xì)牙絲套，用尖嘴鉗上下彎曲安裝柄就可去除。

5、Break-offtool:

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

6、螺紋檢測(cè)  安裝鋼絲螺套之后，用螺紋塞規(guī)檢測(cè)通止規(guī)情況。

6、Ｔhread detect:

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

7、 取鋼絲螺套：在安裝過程中出現(xiàn)問題或者由于鋼絲螺套使用時(shí)間過久需要取出絲套，應(yīng)當(dāng)使用帶有刃的卸套工具對(duì)準(zhǔn)螺套端口，用榔頭猛打一下，用手加力按下手柄反螺紋旋轉(zhuǎn)即可退出鋼絲螺套。
