连杆的钻2-Φ11H7孔夹具设计及机械加工工艺规程工装
摘要
本次夹具设计的主要目的是在确保加工零件质量的基础上，能够见制造成本降到最低，生产的效率大幅度起升，最终，实现利益的最大化。这也是当下国内外加工工艺主要的发展方向。
通过对连杆零件图还有其外形及内部构造的分析，接而对连杆的加工工艺、加工装备，切削用量等等进行确定。该零件是机器的一个重要结构。为机器的正常运转提供强有力的保证，最终使得设备按照预想的方法进行相应的运动。完成连杆零件图还有毛坯图的绘制。
依据指导老师分配的任务，设计钻2-Φ11H7孔钻床专用夹具的设计。专用夹具的设计主要有3部分：定位方案及元件；夹紧方案及元件；夹具体及钻套等设计。经过分析，本次设计的工艺及专用夹具，能够满足生产的需要。

Abstract
The main purpose of this fixture design is to ensure the quality of the processing parts on the basis of the manufacturing cost can be seen to the lowest, production efficiency greatly increased, and ultimately to maximize the benefits. This is also the main development direction of processing technology at home and abroad.
Through the analysis of the connecting rod part drawing and its shape and internal structure, the processing technology, equipment and cutting parameters of the connecting rod are determined. This part is an important structure of the machine. Provide a strong guarantee for the normal operation of the machine, and ultimately make the equipment in accordancewith the desired method of motion. Complete the drawing of the connecting rod part drawing and the blank drawing.
According to the task assigned by the instructor,we design the special fixture for drilling 2- 11H7 hole drilling machine. The design of special fixture mainly includes three parts: positioning scheme and components; clamping scheme and components; fixture body and drill sleeve design. After analysis, the design process and special fixture can meet the needs of production.
Keywords: connecting rod, process, 2-, 11H7 hole, drill press, jig
