Abstract: Aiming at solving the problem of rigid dovetail groove slide rail used in traditional vise using the screw and screw nut to transfer clamping force, which includes high clearance, large movement resistance and uneven clamping force of workpiece, a double directional clamping device of linkage CAM was presented. The simultaneous control of two CAM push rods was realized through the linkage of CAM and connecting rod in this device, which can quickly clamp and locate the workpiece. By changing the hinge position of CAM rocker arm and connecting rod, simultaneous direction control and simultaneous relative direction control were realized. The results show that the device can be positioned once on NC machine tools such as machining center, and the same XY coordinate system can be used to process different bar workpiece. Compared with the traditional vise, the device has good robustness guidance and stability.
Key words: vise; self-centering; quick clamping
