Description of the drawings:
FIG. 1 is a schematic view of a part of a hub to be machined;
FIG. 2 is a schematic view of a partial structure of the present utility model;
FIG. 3 is an enlarged view of a portion of FIG. 2;
FIG. 4 is a schematic view of the partial construction between the present utility model and the hub;
fig. 5 is a partial cross-sectional view of a tool shank.
The specific embodiment is as follows:
in an embodiment, as shown in fig. 1 to 5, a novel special hub processing cutter comprises a cutter handle 10, wherein the cutter handle 10 is cylindrical, and long-strip-shaped vertical planes are formed on the front wall surface and the rear wall surface of the cutter handle 10. The vertical plane is adopted, so that the cutter handle 10 can be clamped on a machining part of a machine tool, and the cutter handle is firm in clamping and difficult to loosen.
The right end of the handle 10 is formed with a transversely extending extension 11, the right end of the extension 11 is formed with an upwardly extending hook 12, the top surface of the extension 11 is formed with a downwardly extending elongated groove 15, and the elongated groove 15 exactly corresponds to the inner convex portion of the rim of the hub 100, so that the hub 100 and the extension 11 are not contacted and kept at a certain distance.
Further, a triangular mounting groove 13 is formed on the front wall surface of the upper end of the hook 12, the bottom of the mounting groove 13 is a sharp groove end, and a circular concave hole is formed in the sharp groove end;
the lower half part of the diamond-shaped cutting knife part 20 is inserted in the mounting groove 13, the upper half part of the cutting knife part 20 extends out of the mounting groove 13, the cutting knife part 20 is fixedly connected to the rear wall surface of the mounting groove 13 through the fixing bolt 1, the upper part and the lower end part of the cutting knife part 20 are respectively provided with a cutting part 21, and the cutting part 21 at the upper part extends out of the top end of the extension part 11.
Half of the cutter portion 20 is a triangular portion, and two side walls of the lower half of the cutter portion 20 are close to two inner side walls of the mounting groove 13.
The inner side walls of the mounting grooves 13 are tightly attached with elastic protective layers 14, and the elastic protective layers 14 are clamped between the inner side walls of the corresponding mounting grooves 13 and the corresponding side walls of the lower half parts of the cutting knife parts 20. The elastic protection layer 14 can have a firm fixing effect on the cutting blade 20, and the loosening probability is greatly reduced.
The middle part of the cutting knife part 20 is provided with a central through hole, the gasket 2 is pressed against the front wall surface of the cutting knife part 20, the screw part of the fixing bolt 1 is inserted into the gasket 2 and the central through hole, the bottom end of the screw part of the fixing bolt 1 is in threaded connection with the rear wall surface of the mounting groove 13, the gasket 2 is clamped between the cutting knife part 20 and the rotating part of the fixing bolt 1, and the rear wall surface of the cutting knife part 20 is pressed against the rear wall surface of the mounting groove 13.
In use, the present embodiment is used by mounting the tool shank 10 on the tool mounting base, mounting the hub 100 on the clamping mechanism for rotation, inserting the extension 11 and the right end portion thereof into the hub 100, and extending the cutting portion 21 at the upper end of the cutting blade portion 20 to the portion to be machined at the inner side wall where the rim of the hub 100 is connected to the hub portion for machining, thereby cutting the portion to form the annular groove portion.
After a certain time of use, when the cutting part 21 at the upper end of the cutter part cannot be cut, and when the cutting capability needs to be improved by polishing, after the fixing bolt 1 is unscrewed, the cutter part 20 is moved out of the mounting groove 13 and rotated 180 degrees, so that the cutting part 21 at the lower part is positioned above, the fixing bolt 1 is mounted again, the cutter part can be processed again, the service time of the cutter part 20 is ensured, namely, after the two cutting parts 21 cannot be cut, the cutter part 20 is mounted for use after the cutter part 20 is dismounted entirely, the replacement frequency of the cutter part 20 is greatly reduced, and the processing efficiency is greatly improved.
