Therefore, most of the processing needs to be completed by high-precision CNC machine tools. The stopper groove of the cylinder bore of the main body is generally in the shape of an arc, and extends from the root of the stopper in both the horizontal and axial directions. Therefore, the existing processing method is generally to use a special tool equipped with a universal angle milling head to mill from the gantry five sides.

[0016] The specific embodiments of the present invention will be described in detail below. In order to avoid too much unnecessary details, the well-known structures or functions will not be described in detail in the following examples. The approximate language used in the following examples can be used for quantitative expression, indicating that the quantity can be allowed to have a certain change without changing the basic function. Unless otherwise defined, the technical and scientific terms used in the following examples have the same meaning as those generally understood by those skilled in the art to which the present invention belongs.

[0017] A method and mechanism for radial and axial grooving in a hole, such as Figure 1~Figure 3 shown.

[0018] In terms of the mechanism, the radial drilling machine 5 is connected to the connecting shaft 7 through the fixed tool handle 6, and the connecting shaft 7 is connected to the base 4 through the connecting plate 8; when processing the stopper of the cylinder hole of the body 1, the cutter body 2 and the blade 3 are embedded in one body, and then the integrated cutter body 2 and the blade 3 are installed on the base 4. The angle of the tool cavity of the fixed cutter body 2 and the blade 3 in the base 4 is consistent with the angle of the stopper groove. The base 4 is positioned by the stopper aperture and plane of the body 1, and the radial drilling machine 5 is used to drive the entire grooving mechanism to complete the processing of the stopper.

[0019] The method includes the following steps: The first step: the staff will hang the body 1 to be processed with the bottom surface facing down on the workbench.

[0020] Step 2: The operator connects the fixed tool handle 6 to the radial drilling machine 5, cleans the burrs, iron filings and other debris on the stopper of the body 1, and sprays a circle of kerosene.

[0021] Step 3: Place the entire grooving mechanism steadily into the body 1, position the base 4 and the stopper of the body 1, adjust the speed of the radial drilling machine 5 to the slow gear and start the radial drilling machine 5. The radial drilling machine 5 is connected to the connecting shaft 7 through the fixed tool handle 6, and the connecting shaft 7 is connected to the base 4 through the connecting plate 8, so that the entire grooving mechanism rotates synchronously. During the rotation process, the operator drives the connecting plate 7 downward by the main shaft of the radial drilling machine 5, and applies downward pressure to the cutter body 2 and the blade 3 through the connecting plate 7. The cutter body 2 will make the blade 3 leak out of the base 4 to process the stopper groove of the cylinder hole of the body 1 according to the direction of the cutter cavity of the base 4. When the cutter body 2 is processed, the guide pin 10 prevents the cutter body 2 from rotating in the base 4. After grooving, the radial drilling machine 5 raises the main shaft, and the cutter body retracts the blade 3 into the base 4 through the spring 9.

[0022] Step 4: After grooving, remove the grooving mechanism, clean the iron filings in the stopper, and check the grooving condition.

[0023] The embodiments of the present invention are described in detail above, but the contents are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the scope of the present invention shall be included in the protection scope of the present invention.
