螺母收口机的设计
机械设计制造及其自动化专业
【摘要】
螺母是机械生产制造中的一种常用零件,其应用范围广,种类多,可以配合螺栓螺柱共同使用形成螺纹紧固件.在生产加工中起到连接,紧固作用,自锁收口螺母因其具有良好的防松、抗振效果,并且结构简单，附加重量轻、强度高等特点在生产加工中更受大家欢迎.但是在目前国内的生产中，螺母收口技术还不成熟，设备还不够先进,同时更缺乏可以实现大批量、现代化的生产加工的设备。
螺母收口机就是一种针对自锁螺母收口加工的设备，本文将在目前已有的螺母收口加工设备的结构基础上，对螺母收口机进行改进设计。主要从其加工的稳定性和精度尺寸定位方面着手改进。并分析研究其在加工过程中因加载而影响的运行平稳.以及在冲压塑性变形过程中影响的精度定位。本结构设计才用液压系统设计主要解决其加载过程中的运行平稳问题、并且设计循环加工过程使操作维护简单易上手，噪音低环境污染少。还适用于各种规格的自锁螺母收口加工及批量生产。

Design of nuts reducing machine
Mechanical design manufacture and automation
【Abstract】
The nut is a common part of mechanical manufacturing, wide application range, variety, can fit bolt stud the common use of formation of threaded fasteners. In the production and processing to connect, fasten nut,
self-locking closing because of its loose, anti-vibration effect is good, and the structure is simple, the additional weight lightweight, high strength characteristics are more popular in the production process. But in the current domestic production, nut shell nosing technology is still not mature, equipment is not very advanced, equipment and lack of can realize batch, the modernization of production and processing.
This machine is a kind of nut for self-locking nuts shell nosing processing equipment, this paper will be in the current structure of nuts reducing machining equipment based on existing, improved the design of the nut sealing machine. Mainly from the processing stability and precision positioning to improve. And the research of the machining process and the effect of loading due to the stable operation of the precision positioning effect. And in the stamping process of plastic deformation. The structure design is designed mainly to solve the problem, the smooth operation of the loading process and design cycle process to make the operation and maintenance easy for hydraulic system, low noise, less environmental pollution. Self-locking nut shell nosing process and batch production can be applied to all kinds of specifications.
