[0002] A machine tool fixture is a device used to clamp workpieces and guide cutting tools on machine tools. Designed specifically for a specific process on a specific workpiece, it contacts the workpiece's positioning base and is used to determine the workpiece's correct position within the fixture, thereby ensuring the workpiece's correct relative position relative to the cutting tool and the machine tool's machining motion during machining. Existing dual-station drilling and milling machine fixtures require a single set of cylinders to translate two sets of movable plates. If there are slight variations in the workpiece's material thickness, while one side of the workpiece is held firmly, the other side may be loose or squeezed, affecting the stability of the workpiece clamping and the equipment's machining accuracy.
