在轴类零件上加工键槽、孔或其它形状时,往往要求槽、孔中心线相对于轴中心线达到严格的对称度。单件小批生产中,由于加工前找正困难,很难达到精度要求,因而容易产生超差品和废品。为此,我们设计制造了测中心具(图1),实践证明,应用效果很好。一主要特点1.找正零件方便、精度高、使用可靠;2.结构简单、制造容易;3.应用范围广,可在车、镗、铣、钻等机床上,找正各种不同尺寸的圆柱、圆锥体零件;4.可提高工作效率和降低劳动强度。
Machining keyways, holes, or other shapes on shaft parts often requires that the groove centerline be strictly symmetrical with respect to the shaft centerline. Small single-batch production, due to the processing is difficult to find, it is difficult to meet the accuracy requirements, and thus prone to ultra-poor products and waste products. To this end, we design and manufacture of measuring center (Figure 1), the practice has proved that the application works well. A main feature 1. Find the parts are convenient, high precision, reliable; 2. Simple structure, easy to manufacture; 3. Wide range of applications, can be in the car, boring, milling, drilling and other machine tools to find a variety of different sizes Cylindrical, cone parts; 4. Can improve work efficiency and reduce labor intensity.
