Abstract
The bearing frame is an important support for bearing, shaft and on-axis parts to achieve rotational movement of the bearing, shaft and on-axis parts. It is an important basic component for the bearing device towork properly. Therefore, the role of the part is important, and the analysis of its processing and manufacturing is of great significance.
The design of the bearing frame is CWA-30103. The main design contents include the analysis of the processing technology of the bearing frame and the design of a special fixture for selecting a machining process. There are four main parts in the analysis of the processing technology of the bearing frame: 1. Analysis of the function and structure of the parts, processing requirements and geometrical tolerances; 2. Analysis and determination of the parts production and manufacturing methods; 3. Parts processing benchmarks, process routes and processing equipment The design and determination; 4, the calculation and determination of cutting data and dosage during the processing of parts.
Through the analysis of the part drawing and the determination of the process route, the right end face of the milling 79 is selected as the special jig processing surface, and the machining machine is the X6132 milling machine. The design content mainly has five parts: 1. Through the process positioning and clamping diagram, the positioning and clamping scheme of the process is designed; 2. The positioning and clamping device and components are selected and determined; 3. The clip specific is designed. Select the tool block, analyze the positioning error, etc.; 4. Design the non-standard parts involved in the special fixture. 5. Draw the parts of the bearing frame and the blank drawing, the fixture assembly drawing and all the non-standard parts drawing on the fixture. Write a manual.
