Description

A Quick Positioning Clamping Mechanism

technical field

The utility model relates to the field of mechanical tool equipment, in particular to a fast positioning clamping mechanism. the

Background technique

Traditional clamping tools such as machine vises, also known as flat pliers, are a kind of general-purpose fixtures, which are often used for clamping various parts on machine tools. For example, when processing parts on milling machines, planers, and drilling machines, machine vises are often used to clamp the processed parts. Fix it on the machine tool table to clamp the workpiece for cutting. The working principle of the flat-nose pliers: use a wrench to turn the lead screw, and the lead screw nut drives the movable clamp body to move, forming the tightening and loosening of the workpiece. The clamping speed is slow and the labor intensity is also great. the
