夹爪/夹持段

Gripping jaws or segments are critical components of mechanical chucks and locking mechanisms used in industrial machinery. These components directly interface with workpieces to apply controlled clamping force, ensuring precise positioning and stability during machining, turning, milling, or assembly operations. They are engineered to maintain consistent grip under varying loads and rotational speeds while minimizing workpiece deformation.

Gripping jaws operate through mechanical force transmission from the chuck body. When the chuck is activated (manually, pneumatically, or hydraulically), the jaws move radially inward or outward along guide slots. This movement creates direct contact with the workpiece surface, generating friction-based clamping force through precisely machined contact surfaces. The force distribution follows mechanical advantage principles, with wedge or scroll mechanisms amplifying input force to achieve required clamping pressure.
