以前加工HF—150转向横拉杆球座的内球面,先在车床上用成形刀加工,然后送热处理车间淬火,淬火后再在车床上用砂纸把内球面打光。由于成形刀的前角及刃倾角几何角度难以控制,加上热处理造成的内球面变形,影响了内球面的成形,导致了球座外径与内球面不同心,球座的几何形状、位置误差及表面粗糙度均达不到图纸要求。影响了转向横拉杆转动的灵活性。 Previous processing HF-150 tie rod ball seat spherical, first in the lathe with a forming knife, and then sent to the heat treatment plant quenching, quenching and then use the sandpaper on the lathe to polish the sphere. As the geometric angle of rake angle and edge inclination angle of forming knife is difficult to control, and the deformation of the inner spherical surface caused by heat treatment affects the forming of the inner spherical surface, resulting in the difference between the outer diameter of the spherical seat and the inner spherical surface, the geometric shape of the spherical seat, the position error And the surface roughness of less than the drawings required. Affect the steering rod rotation flexibility.
