Abstract

A vice has a base fixed to the worktable of a machine, a slider slidable on the base and a fixing-releasing mechanism for selectively fixing the slider to the base and releasing the slider from the base. The fixing-releasing mechanism is provided with an actuator extending through a large hole formed in the base and engageable with the base and the slider. When not applied by pressurized fluid, the actuator fixes the slider to the base, and when applied by the fluid, it releases the slider from the base for the positional adjustment of the slider. The vice also has a piston-cylinder assembly composed of a cylinder tube and a piston assembly slidable in the cylinder tube and surrounding a lead screw in a telescopic manner. When applied by pressurized fluid, the piston assembly as well as the lead screw advances to move a movable clamp element on the slider towards a stationary clamp element fixed on the slider, for clamping a work between both the clamp elements.
