Technical field
Fastener manufacturing equipment technical field of the present invention, more particularly to a kind of closing device for fastener.
Background technique
Using equipment by fastener radially imposed deformation, the position of deformation is to close up, when closing in allows fastener to assemble
Interference fit is formed, and is generated frictional force by radial compaction and is realized locking.The structure of fastener, outer dimension, material, Re Chu
Reason, screw thread manufacturing tolerance etc. can all influence the moment of friction at closing in a certain extent, but when one timing of above-mentioned condition, most
Crucial influence factor is then the closing in size of fastener.For manufacture angle, the dimensional machining accuracy that exactly closes up requires height,
For fastener, requirement of the use environment difference to fastener closing in locking property is also different, especially navigates for aviation
In it, the locking property of fastener is more demanding.It closes up currently, scroll chuck manufacture is usually used to fastener closing in, behaviour
Make very complicated, and due to that can not determine clamping displacement, cause to primarily determine closing in size, it is easy to cause compared with
Big closing in error, is not only unable to reach consistent locking property, is more likely to lead to not using often additional to increase very much
Processing cost.
