摘 要 ABSTRACT This design topic is the tail spline shaft connecting process and drilling jig design parts. Shaft parts takes a very important position in the machinery industry .Under the condition that the majority of primary motors can only provides the rotary motion. The quality of shafts can largely influents the using conditions and the using life of equipments wherever shafts use .In addition to guarantee the quality of a shaft to plan a good enough processing and apply the fitful fixture can play the very important role but to do a good structure design.Researching the processing of a particular air shaft and the design of the Φ2 radial hole content the most of this paper .The shaft has the mid-complex structure and accuracy demand .First,using of machinery manufacturing technology and related knowledge, on the basis of parts and the requirements of the production program, analysis from the blank to the whole process of parts of every process and arrangement, formulate the processing procedure of feasible routes, determine the processing scheme. Then, according to the technical condition requirements of the drawings, the workpiece in the process to solve relevant problems in stepping up and aspects of the process route arrangement, determine the relevant process size and select the appropriate machine tools and tool. Finally, machine tool fixture design reference manual and related aspects of the books, the design of efficient, economic, reasonable and can ensure the quality of processing fixture.
