During the processing of grinding, drilling, etc., the metal sheet workpiece is prone to small up and down vibrations, which will also affect the processing accuracy of the workpiece and is difficult to be applied to the processing of workpieces of different thicknesses. Therefore, it is urgent to improve the existing fixture and provide a multifunctional fixture suitable for different thicknesses.
