Machining Fixture Design Based On Sequential Model

Machining fixtures are accessary devices used in machine0 Its design belongs to engineering design field0 Machining fixture design not only includes New Design, but also includes Adaptive Design and Changing Parametric Design0 In this paper, four kinds of design model are introduced0 These are Sequential Model~ Design Centered ModeL Concurrent Definition Model and Dynamic Mode And two kinds of design strategy which produce one concept or multiple concepts are introduced too0 Different design methods should be chosen in different design phase 0 Based on new design, sequential model and design strategy producing multiple concepts are the first choice for machining fixture design0 The principle and forms of function梞eans tree are introduced0 And the steps of setting up top to bottom function梞eans tree are introduced too in this article0 Concept design model of machining fixture is mentioned 0 The top to bottom function梞eans tree is used to finish concept design of 揷ase and frame boring holes fixture? And valuable analysis method is used in concept design ova] uation of it0 By the evaluation, it is determined as result of concept design that are multiple location forms, mechanical clamping~ connected with machine by hydraulic method0 In machining fixture structure design, three basic principles are mentioned0 these are 揇efinition棗fit to technology functions Simple棗achieve the aim economically. Safe棗safe for both people and environment? The structure design of 揷ase and frame boring holes fixture?are finished in the end of paper, includingassemble drawingand someparts drawings0 Theanalysis of location error is done also0 The conclusion and prospect are made in the end of article0 And some valuable advices are given for the further works0...
