篇一：铣床专用夹具设计说明书

摘要

我国社会主义现代化要求机械制造工业为国民经济各部门的技术进步、技术改造提供先进、高效的技术装备，它首先要为我国正在发展的产业包括农业、重工业、轻工业以及其它产业提供质量优良、技术先进的技术装备，同时还要为新材料、新能源、机械工程等新技术的生产和应用提供基础装备。

本论文是结合目前实际生产中，通用夹具不能满足生产要求，用通用夹具装夹工件效率低、劳动强度大、加工质量不高，而且往往需要增加划线工序，本论文为铣床专用夹具，主要包括夹具的定位方案，夹紧方案、对刀方案，夹具体的设计及加工精度等方面的分析。

本夹具能在加工常规零件的时候使质量进一步提升，并降低劳动强度，能在保证产品质量加工精度的同时批量生产，从而降低生产成本。从而夹具的使用在某种程度上提高实际生产中企业的效益。因而对夹具知识的认识和学习，在今天显的优为重要起来。

Abstract

China's socialist modernization requirements for mechanical manufacturing industry sectors of the national economy progress of technology, technical transformation to provide advanced, effective technical equipment, it must first for China is in the development of the industry include agricultural, heavy industry, light industry and other industries provide good quality, technical advanced technical equipment, but also for new materials, new energy, mechanical engineering of production and application of new technology provides the basis of equipment.

The present paper is combining the actual production, gm can not meet the production requirements, fixture using universal fixture clamping work-piece efficiency, low labor strength, processing quality is not high, and often need to increase crossed process, and special design of a milling machine fixture, mainly including fixture positioning scheme, clamping, of cutter scheme, the concrete and the TAB folder design and machining precision analysis.

This fixture can in processing of conventional parts that quality further ascension, and reduce the labor

intensity, can guarantee the quality of its products processing precision and batch production, so as to reduce the production cost. Thus fixture use in some extent improve the efficiency of enterprises in practical production. Thus to fixture knowledge know and study the optimal in today's show for important up.

Key words: equipment;manufacturing;milling; the machine tool's fixture
