The name is used in machine tool machine vise parallel jaw, called parallel jaw, is a machine tool accessory clamping the workpiece is fixed for cutting in the machine table.
Assembly use: milling machine, drilling machine, medium and flat grinding machinery equipment.
The working principle of rotating machine vise: screw wrench, drive the movable clamp body moves through the screw nut is formed on the workpiece and loosen up.
Machine vise assembly structure is threaded connecting the removable pin and iron fit connection; linear motion of the movable clamp body is changed by spiral motion; the working surface is the friction surface of screw, guide and clearance of shaft and hole.
Machine vise design features: concise and compact structure, strong clamping force, easy to operate. In the nuts generally used metal material material strong, the clamping force remains bigger, usually with the chassis, the chassis with 180 degree to 360 degree scale line plane rotation.
