装配步骤

  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、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 t       he depth of 0.4p after tapping. the best chamfer is 120°, which makes against setting of thread insert if it is too big.
                                                                                                                     

 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、Bottom detect:

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

      

                                                                                                              

4、Installation of thread insert: 

Insert the tool in the dilled hole lower than thethread insert into the tapping pressure.

                                                                                                             
       

      

    5、Break-offtool:

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

 

 

 

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

 

7: a screw, steel wire during the installation process problems, or because the wire use time is too long a screw wire can be removed,

 should be used with a blade sleeve tool on the port, a screw with a hammer blow, with the hand to press the handle to the thread tension 

spinning can exit steel wire spiral sets.
