台式虎钳的三维实体设计及运动仿真

[摘要]在机械制加工中，台虎钳是最常用最普遍的一种夹具，其结构简单装夹迅速，定位准确，使用方便，提高了加工效率和加工精度，也提高了产品质量。台虎钳在提高加工效率的同时也有其不足之处，如不能较好的装夹外形较为复杂的工件、夹紧力不强、夹紧速度较慢等，从而在影响加工效率的同时也造成了一定的经济损失。为了保障正常生产,减少由于夹紧速度过慢造成的损失,设计一种在生产加工中方便、快速地装夹工件，夹紧力强，可以更好地保证工件的加工精度的快速装夹台虎钳十分必要。

本设计主要研究的是台虎钳的快速夹紧和夹紧力，并使用计算机辅助设计软件Solidworks完成整体机构建模与装配，通过对台虎钳底座各部件的三维造型，可以提高Solidworks的三维建模的能力，加深了对零件设计的理解，从本质上提高了软件应用能力。再使用solidworks Motion进行运动仿真分析，设计一种全新结构的快速夹紧台虎钳，克服上述缺点，可以实现自由快速移动活动钳体和装夹速度快，结构紧凑，夹紧力度稳定可靠，使用方便的特点，从而可以更好的在机械加工过程中保证工件的加工精度，提高劳动生产率，降低劳动成本。

Abstract：In mechanical manufacturing processing, vise is the most commonly used one of the most common fixture, its structure is simple the clamping is rapid, accurate, easy to use, improves the machining efficiency and machining precision, also improves the

quality of products. Vise in improving machining efficiency at the same time also has its disadvantages, such as not good clamping shape more complex, the clamping force is not strong, clamping workpiece speed is slow, etc., thereby effecting on the machining efficiency, but also caused a certain economic losses. In order to ensure normal production, reduce the loss caused by clamping speed too slow, designed a convenient, fast in production and processing to the clamping workpiece, the clamping force is strong, can better guarantee the machining precision of workpiece fast clamping vise is necessary.

This design mainly is the study of the fast clamping vise and clamping force, and the use of computer aided design software Solidworks to complete the whole mechanism modeling and assembly, through to the vise base parts of three dimensional modelling, can improve the ability of Solidworks 3 d modeling, deepened the understanding of component design, essentially improve the ability of software applications. To use solidworks Motion movement simulation analysis, design a new structure of fast clamping vise, overcome the above shortcomings, can realize free fast moving clamp body and the clamping speed, compact structure, stable and reliable clamping force, the characteristics of easy to use, in order to better guarantee the accuracy of the workpiece in the process of machining, improve labor productivity, reduce labor costs.
