Study on ensure technology of reconfigurable mechanical interface precision

Theoretical analysis of the precision ensuring mechanism of reconfigurable machine interface using over-positioning technology was thoroughly presented. Based on the obtained rule of over-positioning precision, positioning pin number and interfere probability, the concept of two-state positioning aiming at the positioning difficulty of rigid over-positioning machine interface was proposed. In addition, the high precision ensuring mechanism of repeated positioning technology was analyzed. The results have great guiding significance for the design of precise reconfigurable machine interface.
