Wujiang patch clamp holder fixture manual test fixture frame

Six positioning of the workpiece (2) the application of the principle of six positioning six positioning principle for any shape of the workpiece positioning are applicable, if contrary to this principle, in the central position of the workpiece with the can not be fully determined. However. When positioning the workpiece positioning six principles, we must utilize the specific processing requirements. T different positioning of the workpiece surface shape is different, the distribution of anchor points will vary, the purpose is to use the simplest method of positioning the workpiece in the fixture to obtain the correct position quickly. The reference in the part of the design and manufacturing process, to determine the number of positions of point, line or area must be based on a number of specific points, lines or polygons as the basis for these as the basis of point, line, or polygon is called a baseline. According to the different roles, often put into the design basis and technology benchmark reference categories. 1. Design Basis designer in the design of parts, according to parts assembly relations and the mutual positional relationship between the structure of the parts in the assembly itself structural elements, determined dimension (or angle) of the starting position. These dimensions (or angle) of the starting position as a design basis.
