Common rotary locking mechanisms include threaded, eccentric, cam, and ball types. Each fits different clamping and fixing needs.
Threaded rotary locking mechanism
It works on the screw motion principle. A bolt and nut pair creates axial force for a tight connection. It is common in machinery and automotive applications, such as engine cylinder head bolts and chassis connections. It needs multiple turns and holds position well.
Eccentric rotary locking mechanism
An eccentric wheel changes the radius against a rotating shaft to create clamping force. One turn locks it quickly. Typical uses are machine tool fixtures and mold fixing, where workpieces are clamped often.
Cam rotary locking mechanism
A cam profile pushes a follower to lock or release. It is widely used in automated packaging machinery, such as sealing units and material positioning. The motion path needs high accuracy.
Ball rotary locking mechanism
Balls roll in a defined track to switch between locked and unlocked states. Operation is simple and wear is low. It is common in battery compartment covers and quick-release structures, balancing fast assembly and stability.
For custom locking parts such as threaded studs, eccentric cams, cam plates, and ball tracks, Hansheng Automation can machine from customer drawings in single pieces or small batches.
