Tool setting device of hole machining boring tool and using method thereof

The invention discloses a tool setting device of a hole machining boring tool. The tool setting device of the hole machining boring tool comprises a tool setting instrument body, a dial indicator and a calibration structure, wherein the calibration structure comprises a group of center calibration blocks and at least one group of aperture calibration blocks, the center calibration blocks and the aperture calibration blocks are horizontally-positioned column bodies of which the vertical cross sections are arc-shaped, the center calibration blocks and the aperture calibration blocks are adjacently and fixedly connected, the bottom surfaces of the center calibration blocks and the aperture calibration blocks are positioned in the same plane, the diameter of the center calibration blocks is the same as the rod diameter of a boring tool, the diameter of the aperture calibration blocks is the same as that of a blade of the boring tool, the top end of the tool setting instrument body is provided with a through dial indicator installation hole, the dial indicator is arranged on the tool setting instrument body through the dial indicator installation hole, the tool setting instrument body is positioned on the center calibration blocks, the bottom of the tool setting instrument body is designed to be attached to the outer outlines of the center calibration blocks, and a detection head of the dial indicator is positioned above the aperture calibration blocks by penetrating through the dial indicator installation hole. According to tool setting device of the hole machining boring tool, disclosed by the invention, tool setting is carried out by utilizing a principle of V-shaped block location and calibration tool setting of calibration blocks, the machining accuracy of a hole is effectively ensured, the cost is low, and the operation is convenient.
