ABSTRACT:
A wedge lock workholder for holding workpieces on a machine tool table has a wedge block that has a bore positioned at an angle relative to the support for the wedge block. A wedge slide is slidably mounted in the bore. The angle of the bore provides lateral movement of the wedge slide as the wedge slide is moved along the bore in the wedge block. The wedge slide has a chip shield that slides in a slot in the wedge block to protect the bore opening from entry of chips, and which chip shield serves as a guide for positioning the wedge slide properly. The wedge slide carries a workpiece engaging jaw member at an upper portion thereof which exerts a lateral force on a workpiece to clamp the workpiece against a stop or other clamping member.
