CA6140 lathe processing technology fork and Fixture Design
Abstract
CA6140 fork of the design is a point of order processing technology and procedures in a dedicated fixture design. CA6140 fork of the main surface is two holes on three sides. Generally speaking, the plane of the machining accuracy of the machining accuracy than the hole more easily guarantee. Therefore, the first surface of the design followed the principles of post-holes, and holes with the two-dimensional processing clearly divided into roughing and finishing stages of processing to ensure the accuracy of the hole. First processing the surface of the first parts to be left out of face processing, and then to the bottom parts for rough machining the top face of the base and top parts as to complete the baseline precision of the hole after the processing.And therefore he chose to spare parts as a left-side rough, with a precision of the hole as a benchmark,the whole combination of machine tool selection process, in selected aspects of exclusive jig fixture. Taking into account the specificity of the structure of the parts, as well as a smaller clamping force required for other reasons, the parts of the clamping means clamping screw body to adopt.
