GD518多臂机主传动机构毕业设计

摘要

目前市面上大多数喷水织机都是从国外引进，而我国对于喷水织机的需求量又是逐年提高，因此如何自主开发运行稳定，质量上乘的喷水织机成了新的课题。

本课题主要是基于新昌鹤群机械有限公司开发GD518型多臂机展开的，主要方式是利用日本引进的GD50型多臂机进行再设计和改造，设计制造GD518型多臂机。利用三维建模仿真来确定方案可行性。通过Pro/E对于原凸轮进行仿真，得到所需的数据以及工作曲线，再利用MATLAB对于凸轮进行反求，再通过Pro/E对于反求结果进行仿真和对于原数据的对比，从而实现提高凸轮精度，改善凸轮质量，进而提升多臂机的转速、寿命以及运行稳定性。

本文主要分为以下几个方面来研究：（1）对于整机进行测绘，结合已有数据进行建模。（2）对于难以仅仅通过测绘得到的凸轮进行反求计算，以获得可用的凸轮数据。（3）所得结果利用三维运动仿真来确定方案的可行性。（4）对于加工工序进行简单的分析，利用Pro/E进行数控加工仿真，生产加工代码。

ABSTRACT

Currently on the market most of the water jet loom are introduced from abroad, the demand for water jet loom in the our country is improving year by year, so how to independent development stable running, good quality of the water jet loom has become a new topic.

This topic is mainly based on Xinchang Hequn machinery co., LTD enjoys developing GD518 type dobby, main way is to use Japan imported GD50 dobby design and renovation, design and manufacture of dobby GD518 type. Using three-dimensional modeling simulation to determine project feasibility. Through the Pro/E simulation for the CAM, to get the required data and the working curve, using the MATLAB for CAM reverse, in through the Pro/E for reverse result the simulation and comparison for the original data, to improve precision of the CAM and improve the quality of CAM, thus improve the speed, the life of dobby and running stability.

This paper is mainly divided into the following several aspects to study: (1) for the whole machine of surveying and mapping, combined with the existing data modeling.

(2) is obtained by surveying and mapping for difficult to just reverse calculation of CAM, in order to obtain the available CAM data. (3) the results obtained by using three dimensional motion simulation to determine project feasibility. (4) for processing procedure to carry on the simple analysis, using Pro/E nc machining simulation, the production and processing code.

Keywords: Conjugate CAM mechanism; MATLAB; Pro/E; Reverse; The simulation
