Positioning and clamping of milling face clamps
After years of mechanical processing, our company has summarized some experiences on the design of milling face fixtures. (1) A support plane is formed by three support points to support the workpiece, so that the flatness deviation of the machined surface due to the deviation of the flatness of the blank workpiece can be avoided, and the support point and the compression point should be vertically overlapped to avoid forming a bending moment. Causes deformation of the workpiece. As shown in Fig. 1, due to the elastic deformation of the workpiece caused by the clamping, rebounding after loosening the clamping will cause the flatness to be out of tolerance, which is one of the main causes of the flatness.
