拖拉机拨叉铣专机（卧式）

摘要：

本文主要介绍了X62W型卧式拖拉机拨叉铣专机的性能参数、结构原理，带轮、弹簧夹头的设计计算，刀具的选择和使用，电机的选择以及使用，零件的加工工艺过程以及各种标准件的选择。X62W型卧式拖拉机拨叉铣专机是一台半自动卧式铣专机，它是以现役的X62W型卧式铣床为基础设计出的新型半自动卧式铣拨叉专机。工件以其主轴孔定位，定位心轴置于圆盘工作台上，圆盘工作台主轴呈卧式安置；它的工作过程是：人工上料——自动定位——自动夹紧——自动铣削，铣毕自动松开工件后由操作者取下。 这种专机工作它可以克服现有X62W型卧式铣床工人劳动强度大，生产率低等缺点。X62W型卧式拖拉机拨叉铣专机的工作节拍为每分钟20件，并且具有工作安全、可靠，结构紧凑，运行平稳，产品质量稳定，操作维护简单等多种优点。改造后的X62W型卧式拖拉机拨叉铣专机在生产实践中将会得到有效的应用，而且会取得了良好的效果，在满足生产急需的前提下为企业创造了显著的经济效益。

Design of the milling machine for transmission fork of transmission(horizontal)
Summary: This text mainly introduces the parameters and structure principle of X62W type horizontal milling machine for fork of transmission, with wheel and spring chuck design calculate, choice and use of cutter and electrical machinery, preparation method course and choices of different standard component of part. X62W type horizontal milling machine for transmission fork of transmission is one set of semi-automatic horizontal mill special plane. It regard current X62W type miller as the half automatic on that stir the fork special airplane. The workpiece fixing with its sipindle hole. The spolting spindle is placed in disc worktable. Its working process is: anticipate on the artificial- automatic position- automatic clamp- automatic milling, after milling unclamped the work piece automatically and taken down the workpiece by the operator. Use this kind of special airplane works can overcome the current X62W type miller much disadvantage such as big labor strength bi, low productivity. The X62W type horizontal milling machine for fork of transmission’s work tempo is 20piece every minute. And have the work safety, dependable, construction tightly packed, circulate steady, product quantity stability, operation and maintenance simple etc. various advantages. The reconstructing of X62W type horizontal milling machine for fork of transmission would getting application effectively, and will obtain the good result, It will creats evidence economic performance for the business enterprise at the need of the premise bottom.
Keywords：Dial fork mill special plane, solid pulley, spring chuck.
