Abstract

The paper introduces the Hubei Province, Dongfeng (Shiyan) equipment manufacturer

Dongfeng Nissan the L42L shock absorber assembly right side of the fixture design.

This paper focuses on computer-aided design and manufacturing, drawing two-dimensional

engineering drawings using AutoCAD, Application of three-dimensional software of 3D

digital modeling, fixture virtual assembly, as well as parts of the main parts and

components manufacturing simulation, interference analysis. The structure of the

fixture part of the main components of the technical requirements are explained in

detail; also analyzed and compared the economic and technical feasibility of the

technology program, the fixture parameters and the theoretical calculations; The clamp

design procedure are illustrated, and the relevant data for checking its rationality,

the rationality of the design of the fixture.

Keywords ：The shock absorber assembly ， Fixture design ， Two dimensional engineering

drawings，Three dimensional modeling.
