Abstract
The utility model provides a mechanical automatic centering mechanism which is a three-point centering mechanism mounted on a platform. The mechanical automatic centering mechanism comprises a linear motion driving part fixing a crank arm guide driving plate, two Archimedes spiral curve slide tracks arranged on the two symmetrical sides of the crank arm guide driving plate respectively, wherein the pins of the crank arms with symmetrical sides being symmetrically hinged on a clamping plate are glidingly arranged inside the Archimedes spiral curve slide tracks. Under the drive of the linear motion driving part and the guiding of the Archimedes spiral curve slide tracks, the absolute travel distance of each point on the travel track of the left and the right crank arms relative to the standard centering base point is equal to the absolute travel distance of the top end of the linear motion component relative to the standard centering base point at this moment all the time, thereby achieving the purpose of automatically fixing and clamping the to-be-centered component in the standard centering position. The utility model also provides an automatic centering machine formed by the mechanical automatic centering mechanism. With the technical scheme, the utility model has the technical characteristics of simple structure, high automation degree and high centering accuracy.
