Description

Technical Field

[0001] The present invention specifically relates to a clamping device for machining side holes of nuts. Background Art

[0002] A nut is a screw cap, a part that is screwed together with a bolt or screw rod to play a fastening role. It is an element that must be used in all manufacturing machinery. According to different materials, it is divided into several major types such as carbon steel, stainless steel, and non-ferrous metals (such as copper).

[0003] Ordinary nuts are prone to loosening in a vibrating environment. To prevent this, in a high-vibration environment (such as aviation, racing cars, and heavy machinery), perforations are made on the side of the nut. The holes are used to pass through metal wires (safety wires) to lock multiple nuts or bolts in series to prevent loosening due to vibration. This method ensures that once a certain nut starts to loosen, it will affect other components, thereby reminding maintenance or preventing further loosening. However, when the size of the nut is small, it is prone to displacement during the side perforation process, resulting in low efficiency of side hole machining. Summary of the Invention
