Promote Frame Parts Machining Process and Special Fixture Design
Abstract
Machining process planning design and machine tool fixture design play an important role in parts manufacturing. To ensure the processing quality of parts and produce qualified products, a feasible machining process route and a reasonable fixture design should be formulated. The content of this design can be divided into two parts: the design of machining process regulations and the design of special fixture for machine tools. Firstly, the driving frame parts of B6065 planer are analyzed in detail to understand its function and processing requirements. Two sets of technological routes were worked out. Through analysis and comparison, the technological route scheme was finally determined, the processing allowance and process size were determined, the appropriate processing equipment was selected, the cutting parameters were determined, and the basic working hours needed for processing were calculated. Using the basic principle and method of fixture design, the design scheme of fixture is worked out, and the special fixture is designed for the drilling process of parts processing. 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.
