裝配步驟

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、攻絲用相應規格的絲套專用絲錐攻絲，用戶可根據所需內螺孔的精度，適當選擇攻絲方法和潤滑方式，盲孔攻絲時要用力適當，以防止絲錐折斷，攻絲后應清理干凈螺紋孔，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檢測底孔通止規情況。

  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用手動安裝扳手安裝絲套，將絲套放入套筒槽口內，絲套安裝柄朝下，芯軸穿過絲套卡住安裝柄，擰入導套處，對準基體螺孔，順時針轉動芯軸。應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，要將絲套安裝柄沖斷，一般用沖斷器對準安裝柄，用200g左右的榔頭猛擊一下即可去除，對于18×2.5以上的粗牙絲套和14×1.25以上的細牙絲套，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、螺紋檢測安裝鋼絲螺套之后，用螺紋塞規檢測通止規情況。

6、Ｔhread detect:
After installing the screw sets, detected the pass and stop instrument by thread plug guge.

7、取鋼絲螺套：在安裝過程中出現問題或者由于鋼絲螺套使用時間過久需要取出絲套，應當使用帶有刃的卸套工具對準螺套端口，用榔頭猛打一下，用手加力按下手柄反螺紋旋轉即可退出鋼絲螺套。
