车床组合夹具设计
摘 要
根据六点定位原理和定位基准的选择原则，采用长V型块，支承块和定位挡铁定位。长V型块置于拱形肋板后限制x轴的两自由度和z轴的两自由度，挡铁置于孔端限制绕y轴旋转的自由度，支承块置于肋板下方限制沿y轴移动的自由度。依据相关原理计算定位误差。根据夹紧方式的选择原则，选择夹紧元件为压板压头和V型块，然后通过切削力进行夹紧力的计算。夹紧的动力装置选用手动压紧装置。按照定位元件和夹紧元件设计连接件。
以所选元件和装置为基础确定夹具总体布局和夹具体的结构形式，并确定好定位元件在夹具体上的位置。绘制夹具方案设计，进行工序精度分析。对以上设计进行审核。最后设计夹具总装配图。

Lathe modular jig and fixture design
Abstract
According to six localizations principles and selection principle of the localization datum, using the long V block, the supporting block and the localization comes true the hard localization. The long V block putted in the arch ribbed plate to limit two degrees of freedom in the x axis and the z axes two degrees of freedom, the iron putted in the hole end limit to the degree of freedom which circle the y rotation of axis, the supporting block putted under the ribbed plate to limit degree of freedom along the y axis migration. Position error is reckoned by the correlation principle. According to the way of the selection principle, discharge head and V block is selected to clamp the part. Then computation of the strength is achieved by carrying on through the cutting force clamps. The power of clamps is from the hydraulic unit. Design of bridge piece is according to the location part and the clamp part. The guide part designing in this topic is not requested because the cutter bar is short. Other parts and equipment are designed following last process.
The jig overall arrangement and concrete structure of the body clamp are determined with the above part and the equipment. The position of the components in the kits specific location must be guaranteed, and then design the jig, carry on the working procedure precision analysis. The design review is following. Finally the jig assembly drawing is achieved.
