- The design of the content relates to the machinery manufacturing technology and machine tool fixture design, metal cutting machine tool, tolerance and measuring and other aspects of knowledge.
CA6140 fork 831008 processing technological process and the car end fixture design is to include parts machining process design, process design and fixture design in three parts. In the design process should first of all parts for analysis, to understand the parts of the process to design the structure of the blank, and select good parts processing base, design parts of the process route; and then the various parts of process dimension calculation, is the key to decide all processes equipment and cutting parameters; then special fixture design, selection and design of a jig for the various components, such as positioning devices, clamping elements, the guide element, clamp and the machine tool connecting parts and other components; calculate fixture is produced when the positioning error of fixture structure, rationality and deficiency, and later in the design of improved.
Keywords: The craft, the working procedure, the cutting specifications, clamp, the localization, the error
