该项目基于工作持有设备的需求。这种设计和制造将使操作如钻孔，铰孔，攻丝过程甚至是作业配置文件的易棱镜。我们的项目主要由设计和制造组成“叶夹具”它将绝对设计覆盖到工件的指定尺寸。角夹具允许在工件的一侧钻孔钻孔，使用单一位置和夹紧操作，这节省了时间并提高生产率。

介绍

大规模生产的目标是通过减少设置成本和人工疲劳来提高生产率和准确性。实现大批量生产目标的常见做法之一是使用夹具。让我们考虑这样一个例子，一个人得到1000个产品的订单，在一个工件上钻三个孔。在这种情况下，设计人员会利用方尺、直线度、划线器、中心冲孔器等来确定每个孔的位置。一般采用试错法，直到孔的轴线与钻的轴线正确对准。因此，需要花费大量的时间来保持准确性。最终增加了操作人员的疲劳。因此，操作者使用夹具来定位和引导钻头进入适当的位置，而不是通过正方形、直线度、划线器、中心冲头等来确定每个工件上的每个孔的位置。通过消除单独的标记、定位和频繁的检查，钻头夹具提高了生产率。互换性是夹具的优点之一。 There is no need for selective assembly. Any of the parts will fit properly in the assembly and all similar components are interchangeable. In addition, a jig reduces the repetitive nature required for drilling a hole, as the locating, clamping and guiding are done by jig itself. The tool-guiding element helps in setting of tool in correct position. Hence, skilled workers are not required. Drill jig makes it possible to drill, ream and tap holes at much faster speed and with great accuracy as compared to holes produced by conventional hand methods. The responsibility for accuracy of hole location is taken from the operator and given to the jig. Jig can be defined as a work piece holding and locating device that positions and guides or controls the cutting tool. Drill jig is device to ensure a hole to be drilled, tapped or reamed in the work piece at proper place. Leaf jig consists of a clamping device to hold the part in the position under hardened steel bushings. Drill passes through the steel bushings during drilling operation. The drill is guided by these bushings. Generally work piece is held by jig and the jig is arranged in such a way that the work piece can be quickly loaded and unloaded.

•消除单独打标、定位和频繁检查。

•由于高夹紧刚性，由于速度，进料和深度的增加，操作时间减少。

它在大规模生产中非常有用。

•可以使用不熟练的或半熟练的操作员来节省劳动力成本。

•它使工具部分自动化。它减少了机器零件质量控制的开支。

限制：

•它仅用于小尺寸组件。它仅用于带法兰的肘部管，其高度为mm。

•导致偏转的力可能来自处理。没有特殊的方法可以去除钻孔生产的芯片。所以它需要单独的时间。

应用程序

•批量生产以下是使用夹具装配、研磨、镗孔、铣削、拉削、规划、钻孔、锯切、成型、整形、测量、冲压、磨削、攻丝、热处理、测试、珩磨、车削、焊接检查等生产操作的部分清单
