ABSTRACT
Machining process regulations are the main technical documents to guideworkshop production, important materials for production preparation and management preparation, the basic basis for building or expanding factories andworkshops, and also facilitate the exchange and promotion of advanced experience. The correct process rules can stably guarantee the quality of the product and obtain high productivity economic benefits, and can make the production smoothly and smoothly.
The parts given in this article are geared shafts. Geared shafts are typical shaft parts. Transfer motion and power to gears. Through the analysis of the part drawings, cultivateyourself to establish the correct processing ability of the product, andyou can also deepenyour understanding of the theory learned, and learn to use the knowledge to analyze and solve some practical problems.
This time, the detailed design of the processing technology of the gear transmission shaft is designed. Draw up the machining process route, calculate the machining allowance, cutting amount, and dimensional tolerances in detail, determine the process sequence machining allowance, machining hours, and machining, and select the processing equipment. Through this design,you can master the analysis of the processing of parts, the preparation and steps of process cards.
Draw parts drawing, rough drawing and processing procedure diagram, fill in processing card and processing procedure card,write design instruction, etc.
Keywords: gear; transmission shaft; processing technology; three elements of processing
