Abstract:
The content of this design is to formulate the shell processing technology and the design of turning clamping fixture, as follows:
1. The analysis of parts is mainly the function analysis and process analysis of parts. Through the analysis of parts,we can understand the basic situation of parts, and process analysis can know the processing surface and processing requirements of parts. According to the processing requirements of the part drawing, the manufacturing form and size of the blank are determined.
2. Select the base plane to determine the rough and precise datum in the process of processing. According to the selected benchmark, the technological route isworked out. Usually, two kinds of technological route areworked out. Through the comparison and analysis of technological schemes, a processwhich can reasonably guarantee the geometric shape and dimensional accuracy of parts is selected. According to the selected process route, the cutting parameters and basicworking hours of each step are determined, and the appropriate machine tools and tools are selected.
3. Designing clamping fixture for turning. The positioning scheme and components, clamping scheme and components are determined, and then the cutting force, clamping force and positioning error are calculated. Complete the drawing of parts and fixture assembly, fixture assembly drawings and non-standard parts drawings, etc.
Keywords: shell, process, turning, fixture
