下压治具
在工件组装或加工过程中，为确保装配工艺达标，并使工件表面达到图纸规定的尺寸、公差、几何形状以及与其他表面的定位精度等技术要求，加工前必须对工件进行正确的定位和可靠的夹紧。
During workpiece assembly or machining, to ensure that the process meets the required standards and that the workpiece surface achieves the specified dimensions, tolerances, geometrical features, and positional accuracy indicated on the drawings, the workpiece must be properly positioned and securely clamped before machining.
