Automatic gear milling machine

The utility model discloses an automatic gear milling machine, which comprises a positioning jig, a rotating tray, a gear shifting mechanism, a gear shifting mechanism, a gear shifting mechanism, a gear shifting mechanism and a gear shifting mechanism, and is characterized in that a workpiece to be machined is fixedly placed on the rotating tray and rotates synchronously with the rotating tray; the gear milling mechanism comprises a cutter, and the cutter can be used for milling a tooth-shaped structure on a workpiece; the moving mechanism is connected with the positioning jig and drives a workpiece on the positioning jig to move to a cutter for machining; according to the automatic gear milling machine designed in the scheme, a disc-shaped workpiece is fixedly placed on the rotating tray, and after the rotating tray rotates to a specified angle, the workpiece on the rotating tray is driven by the moving mechanism to move to a cutter to mill a tooth-shaped structure; and then the tray retreats and rotates to
