摘  要
本设计课题是“注塑机尾板机械加工工艺规程及夹具设计”。该尾板是注塑机最主要的部件之一，它与注塑机的四根拉杆配合，可沿拉杆方向滑动。主要作用一是安装液压缸，二是连接拉杆，形成合模力。本设计旨在对该零件进行加工工艺方案的设计及其相对应的专用夹具的设计，以保证该零件的加工质量并提高生产效率。由此我们首先对尾板的结构和技术要求进行了仔细的分析，然后参考相应资料，确定了一套较合理的机械加工工艺方案，并且确定了各工序的加工余量、工序尺寸、公差及切削用量等参数，完成了工序过程卡、工序卡。然后，为了提高劳动生产率，降低劳动强度，保证加工质量，要设计一些专用夹具，为此选择了第14道铣支耳外侧面工序进行夹具设计，确定了夹具的定位、夹紧方案，进行了夹紧力和夹具的误差分析，并绘制了夹具装配图。

ABSTRACT
The topic of my graduation design is "The machining process procedures and Fixture design of the Injection tail board " . The tail board is the most import part of Injection machine that cooperate with four bars , and can glide by the direction of the bars . The main function are installing hydraulic cylinder and connecting bars to form mold clamping force . This project is aim at designing the processing technic scheme of components and the corresponding fixtures used in special purpose to improve the production efficiency . First of all , I should make a analysis about the structure of tail board and technical requirements carefully , then refer to the relevant materials to determine a set of reasonable machining process procedures and parameters , such as : machining allowance、size、tolerance、cutting date of each process . Finished the process cards . In order to improve the labour productivity、reduce the intensity involved in the labour、ensure  the processing quality , I should design some special fixtures .so that I choose the 14th course process of milling journal stirrup outside part to make the fixture design and make a analysis of clamp force and fixtures ' error、ensure the location of fixture , and the clamp scheme . Finally, assembly drawing of the fixtures .
