The invention relates to a pin steering conveying mechanism. The pin steering conveying mechanism comprises a mechanism fixing plate; a portal frame is fixedly connected to the upper end of the mechanism fixing plate; one side of the portal frame is provided with a fixed conveying groove; a square groove block is fixedly connected to one end of the fixed conveying groove; a rotating air cylinder is fixedly connected to the lower end of the mechanism fixing plate; a rotating conveying groove is formed in a cylinder rod of the rotating air cylinder; the rotating conveying groove is rotationally formed in the inner side of the square groove block; a transversely arranged first push air cylinder is fixedly connected to the lower side of one end of the portal frame; a sliding way is disposed on the lower portion of the portal frame; an air cylinder fixing block is slidably disposed on the sliding way; the air cylinder fixing block is connected with the cylinder rod end of the first push air cylinder through a connecting block and a floating joint; a vertically arranged second push air cylinder is fixedly connected to the air cylinder fixing block; a shifting fork is fixedly connected to the cylinder rod end of the second push air cylinder through a shifting fork fixing block; and the direction of the shifting fork is correspondingly matched with that of a groove line of the fixed conveying groove. By means of the pin steering conveying mechanism, steering conveying of small cylinders such as pins can be achieved, and the pin steering conveying mechanism is simple in structure, low in cost and high in utilization rate of the equipment space.
