我厂齿轮车间生产工农10型手扶拖拉机底盘齿轮,其中双联齿轮有三种,过去,磨双联齿轮内孔夹具,采用等分三块阿基米德螺旋线式斜块,效果不理想,这种夹具缺点是:制造复杂、工艺性差,加工产品质量低,操作麻烦。针对上述问题,我们车间技术组革新成功了一种双联齿轮磨内孔夹具。该夹具结构简单、制造容易、操作方便、加工质量稳定、可靠。一、工作原理 I plant gear workshop workers and peasants 10 tractor chassis gear production, of which there are three double gear, in the past, double-gear grinding hole fixture, using three equally divided Archimedes helix oblique block, the effect is not satisfactory, Disadvantages of this fixture is: manufacturing complex, poor workmanship, processing of low quality products, operating troubles. In response to the above problems, our workshop technology group successfully developed a double gear grinding hole fixture. The fixture has the advantages of simple structure, easy manufacture, convenient operation, stable and reliable processing quality. First, the working principle
