Multifunctional quick replaceable double-acting clamp paw bench vice

Abstract

The present invention discloses a multifunction quick change double acting pawl table vice comprising a vice body, a guide screw, two movable vice pawls and a nut; driving blocks are equipped between the nut and the vice pawl and the connection pattern between the movable vice pawl and the driving blocks is a coattail type; a flexible pin is equipped between the movable vice pawl and the driving blocks to form a flexible connection; the guide screw rotates around the nut to drive the two driving blocks and the driving blocks push the movable vice pawls to slide in opposite directions (or reverse directions) to form a jaw which grips (or holds) the work piece; the vice body is a rectangular one and the five sides of the vice body are equipped with screw holes, pin holes or strip grooves; the guide screw is equipped in the vice body which realizes that the table vice can be laid horizontally, on side or vertically on the machine tool workbench and the vice body can be combined; a fixed vice pawl is equipped between the two movable vice pawls and the fixed vice pawl is fixed on the vice body which can realize the conversion between single station and two stations. The materials of the fixed and movable vice pawls can be steel, aluminum or copper and can be hard pawls or flexible pawls; the movable vice pawls are convenient for replacement and can grip work pieces of various mold surfaces.

Description

technical field [0001] The invention relates to a bench vise, in particular to a bench vise for machining and cutting machine tools for clamping workpieces, and belongs to the technical field of machine tool accessories. Background technique [0002] The existing common bench vise has a lead screw that rotates around the fixed screw nut, and the lead screw drives the moving jaws to fit with the fixed jaws of the pliers body to form a jaw to clamp the workpiece. This type of bench vise has the following problems: 1) The moving jaws are directly connected to the lead screw and cannot be replaced at will; 2) The moving jaws are all hard jaws and cannot be processed at will. For workpieces with complex shapes, clamping is often unreliable or cannot be clamped; 3 ) does not have the function of expanding claws; 4) the installation method on the machine tool table is single and cannot be combined; 5) the manufacturing process is complicated. Contents of the invention [0003] T...
