  • Description: In the mass production of box and monoblock parts, due to the clearance between the traditional location of one plane and two pins, subsequently the complete unification of datums of each process cannot be reached, which easily causes the problem of unstable product quality. A new clearance-free locating method by using two elastic multi-tooth cylindrical pins instead of traditional cylindrical pins and diamond pins is proposed. The elastic interval of the teeth of the locating pin is searched by the least square method, then tolerance zone of the center distance of the locating hole only satisfies to the elastic interval. The clearance between pin and hole is eliminated through self-adaptive fitting relied the resilience of elastic teeth of locating pin, consequently the real unification of benchmarks of each process is realized. Ultimately, the validity of the proposed clearance-free locating method is verified by numerical simulation.
