Ball type oil hole drilling locating tool

The utility model provides a ball type oil hole drilling locating tool which comprises a rotor mandrel, a tool base and a handle. The handle is connected with the tool base. A ball for enabling the rotor mandrel to rotate is arranged between the rotor mandrel and the tool base, a raceway trunking which enables the ball to rotate is formed in the end face of the rotor mandrel, the raceway trunking surrounds the end face of the rotor mandrel by one circle, a plurality of blind holes which enable the ball to freely roll in and roll out are formed in the raceway trunking, and a ball locating device is arranged on the tool base. In the production process, a worker only needs to place a workpiece on a locating outer circle of the rotor mandrel, locks the workpiece, rotates the rotor mandrel, and drills a hole when the ball stops at one position, therefore, the position of the hole can be accurate, the phenomena of drilling missing, drilling mistakenly, much drilling and the like can be avoided, and efficiency is multiple times higher than original efficiency.
