机床夹具在机械制造工厂中占有重要地位,最优的夹具设计方案应当是在满足产品质量和产量的前提下,操作方便、结构紧凑、制造简单。要达到这个目的,设计人员除熟练地掌握标准的定位夹紧元件外,还得熟悉工艺过程和产品结构,并巧妙地利用零件的结构特征来设计夹具,就能取得良好地效果。如图1丝杆,在制作加工T40×6螺纹的夹具时,原夹具(图2), Machine tool fixture occupies an important position in the machinery manufacturing plant, the optimal fixture design should be to meet the product quality and yield under the premise of easy operation, compact structure, easy to manufacture. To achieve this goal, in addition to skilled designers to grasp the standard positioning clamping components, but also have to be familiar with the process and product structure, and clever use of structural features to design parts fixture, you can get good results.
