The invention discloses an automatic arranging machine for a disc type transformer skeleton. The automatic arranging machine comprises a machine frame, a cam, a stacking platform and two driven mechanisms, wherein the two driven mechanisms have fully-identical structures and are opposite in position; the driven mechanisms comprise two magnetic disk containers, pre-placement grooves, two push plates and a push rod adapted to the cam, the stacking platform, the two magnetic disk containers, and a shell of a motor driving the cam to rotate, are all fixedly arranged on the machine frame, and the pre-placement grooves are fixed with the magnetic disk containers and are located between the magnetic disk containers and the stacking platform; clamping devices, which are used for containing two cylindrical magnetic cores, are arranged on the stacking platform; one end of the push rod is fixed with the push plates, the other end of the push rod is in contact with the cam so as to drive the two push plates to move on the same straight line, and the stacking platform is located between the two push plates; and two groups of clamping grooves are arranged on the upper side faces of the push plates in a raising manner, clamping openings of the clamping grooves face to the stacking platform, and the back sides of the clamping grooves are transited to the upper side faces of the push plates through obliquely-downward oblique planes. According to the automatic arranging machine for the disc type transformer skeleton, the stacking of disks can be mechanically completed, so that the manual work is avoided, and meanwhile, the production efficiency is increased.
