Generally, screw holes that are frequently used are prone to damage. The reasons for damage to machine screws holes are generally as follows: one is that the effective depth of the bolts screwed into the screw holes is too shallow, which makes the threads fail due to strong shearing force; the other is This may be that the threaded part of the bolt has flashing burrs or dirt, or the dirt has entered the screw hole, and the screw hole is scratched when the bolt is screwed in, which accelerates the wear of the thread surface, and slowly reduces the shear resistance until it is broken. . And in the damaged machine screws holes, some accessories are not low in value. If a screw hole is damaged and therefore wasted, the loss is too great and unacceptable. Then, the screw holes of these mechanical accessories are What should I do if it is damaged? Is there any quick way?
The method of repairing damage to the screw hole is actually a very simple thing, that is, use the special tap of the threaded sheath product to re-tap the damaged screw hole, and install the threaded sheath, the damaged screw hole will be Get a quick fix.
Repair the screw holes of the mechanical fittings after installing the threaded sheath, it can improve the connection strength of the screw holes after the repair, install the threaded sheath in the screw of the machine, it can
Improve the connection conditions and increase the bearing capacity and fatigue strength of the threaded connection: the use of wire threaded sleeves can eliminate the pitch and thread deviation between the screw and the screw hole, and evenly distribute the load, thereby improving the load-bearing capacity and fatigue resistance of the threaded connection strength. It can be used for the connection and fastening of hard, brittle and fragile materials such as ceramics, bakelite, and glass. Effectively prevent fragmentation.
