在加工轴类零件时,常遇到铣键槽定心以及轴钻孔垂直相交问题,所以我设计了高精度定心虎钳。经使用证明定心准确,夹紧力大,并备有各种规格的可换钳口,加工最大直径为60毫米。虎钳经一次校正后,工件直径变换不会影响定心精度。虎钳导轨采用双圆柱结构(见附图),双圆柱12材料为GCr 15,淬硬HRC 60,导轨硬度高,耐磨性好。由于圆柱导轨间隙小,精
In the processing of shaft parts, often encountered in the milling keyway centering and vertical shaft hole intersection problems, so I designed a high-precision centering vise. The use of proven centering accuracy, clamping force, and equipped with a variety of interchangeable jaws, the maximum diameter of 60 mm. Vise once calibrated, workpiece diameter change will not affect the centering accuracy. Vise guide rail with double cylindrical structure (see photo), double cylinder 12 material GCr 15, hardened HRC 60, rail hardness, good wear resistance. As the cylindrical guide clearance is small, fine
