Abstract
The design of machining process planning and fixture design plays an important role in parts manufacturing. Only by establishing feasible machining process route and designing reasonable fixture can the machining quality of parts be ensured and qualified products can be produced. The content of this design can be divided into two parts: machining process design and fixture design. Firstly, the parts of B6065 planer's pushing frame are analyzed in detail to understand its function and processing requirements. Through analysis and comparison, two sets of process routes are established. The machining allowance and process size are determined. The appropriate machining equipment is selected, the cutting parameters are determined, and the basicworking hours are calculated. According to the basic principle and method of fixture design, the scheme of fixture design isworked out, and the special fixture is designed for the process of drilling and reamingΦ 10 mm andΦ 16 mm hole in the machining of parts. The processing technology of this design is reasonable, the fixture is feasible, efficient and labor-saving,which can meet the processing requirements of parts and ensure the processing quality.
Keywords: machining; process specification; special fixture; pushing frame
