我厂设计成一具多用的齿轮油泵泵体盖车中心距夹具,以一个已加工孔及端面为基准加工另一个孔。经长期使用证明,此夹具结构简单、操作方便,使用可靠、加工的工件精度高、质量好、互换性强。夹具结构见附图。使用方法1.拆下压板7及双头螺栓8,把夹具安装在C 620车床主轴上。2.将定位销4放入中心孔内,通过更换块规11及调整支承钉1,保证定位销对车床主轴的不同轴度不大于R0.005毫
Our factory designed a multi-purpose gear pump body cover truck center distance fixture, with a processed hole and the end face of the base processing of another hole. The long-term use proved that the fixture has the advantages of simple structure, convenient operation, reliable use, high accuracy and good quality of the processed workpiece, and good interchangeability. Fixture structure see attached map. Method of use 1. Remove the pressure plate 7 and studs 8 and attach the clamp to the C 620 lathe spindle. 2. The positioning pin 4 into the center hole, by replacing the block gauge 11 and adjust the support pin 1, to ensure that the positioning pin on the lathe spindle axis is not greater than R0.005 milliseconds
