What Is a Stop Bolt?
A stop bolt, also known as a stopper bolt, is utilized in machining operations such as metal processing to position and secure workpieces. To prevent loosening, it is often paired with a locking nut. Considering its exposure to impacts, it is designed with both strength and impact resistance in mind, achieved through material selection and specific mechanisms.
Uses of Stop Bolts
Stop bolts are employed in various machining contexts as mechanical stoppers and in linear stopper assemblies for positioning workpieces. They are also used in seismic equipment to secure bases. In some specialized setups, stop bolts are integrated with touch switches, serving dual roles as both stoppers and switch activators, thereby enhancing efficiency and durability against collisions.
Principle of Stop Bolts
The design of stop bolts varies according to their use. When functioning as stoppers, they feature robust heads, often quench-hardened or flat-shaped for better impact resistance. To minimize impact, some bolts have heads with resin protection like urethane or include shock absorbers.
For positional adjustments, stop bolts are made from durable materials like SUS304 steel or undergo heat treatment for increased hardness. Fine threads are also common for precise adjustments.
In configurations with touch switches, where impacts are expected, stop bolts are made from materials with sufficient strength and may also be designed for water and oil resistance, depending on the equipment’s specific requirements.
