Embodiment Construction

[0040] Referring to the drawings, wherein like reference numerals indicate like parts in different drawings, reference numeral 10 is directed to a preferred embodiment of the present invention.

[0041] refer to figure 1 , showing that the threaded insert 10 is fully installed in the object 12 in order to replace the damaged thread 32 in the object hole ( Figure 4 ) preferred embodiment. The object 12 may be any means required for threaded holes for assembling the second part or for attaching other means to the object. hole 18 ( Figure 5 ) is drilled into the object 12 with a drill bit 34 and a matching thread 19 is made on the wall of the hole 18 (FIG. 7).

[0042] The threaded insert 10 can be turned into the threaded hole of the object until the top surface 21 of the threaded insert 10 is flush with the upper surface of the object 12 . If the top surface 21 protrudes above the object 12, it may be left as such or ground flat. Such as figure 2As shown, the recess 11...

Abstract

The present invention relates to a system and a device for replacing a damaged thread in an object (12) with the same thread as the damaged thread, i.e. enlarging the original threaded hole and inserting a threaded insert (10) in the new threaded hole of the object, the insertion The piece has the same internal thread as the original threaded hole. A threaded insert secures in an enlarged hole using threads that hold it securely in place. When the threaded insert is screwed into the enlarged threaded hole, a recess formed under the drive head of the threaded insert causes metal to flow into the recess to create a seal between the threaded insert and the object.

Description

technical field [0001] The present invention relates to a system and apparatus for replacing a damaged thread in an object, and more particularly the present invention relates to a system and apparatus for replacing a damaged thread which will replace the thread with a permanently installed insert also between the insert and A seal is provided between the objects to be repaired. Background technique [0002] When internal threads machined in objects are damaged, they are sometimes repaired by tapping the damaged thread with a tap in order to restore the thread shape. However, if the thread is damaged to such an extent that tapping with a tap will not restore its function, the thread must be replaced. This is accomplished by drilling the original thread with a drill bit larger than the major diameter of the thread and re-tapping the hole with a thread of larger diameter. This method, while providing useful threaded holes, would require a different size fastener than the ori...
