Specific embodiment

Such as Fig. 3, a kind of aluminium alloy wheel hub inside and outside circle Machining of Curved Surface combination knife, including knife bar 10, inner circle Machining of Curved Surface blade 20, outer circle Machining of Curved Surface blade 30.

Such as Fig. 3, the knife bar 10 is equipped with the first knife bar branch 11 and the second knife bar branch 12, and the first knife bar branch laterally sets It sets, the second knife bar branch is longitudinally disposed, wherein the second knife bar branch 12 is the straight line extension of knife bar main body 100.Described Angle between one knife bar branch 11 and the second knife bar branch 12 is 90 degree.

Such as Fig. 3, the inner circle Machining of Curved Surface blade 20 is mounted in the first knife bar branch 11, the outer circle Machining of Curved Surface knife Piece 30 is mounted in the second knife bar branch 12.Angle between inner circle Machining of Curved Surface blade 20 and outer circle Machining of Curved Surface blade 30 is 90 degree.Wherein, the nose radius of outer circle Machining of Curved Surface blade 30 is R1.2, and the nose radius of inner circle Machining of Curved Surface blade 20 is R3.0。

Such as Fig. 5, the inner circle Machining of Curved Surface blade 20 is detachably connected with the first knife bar branch 11, is convenient for changing blade. Specifically, the first knife bar branch 11 opens up the first insert pocket 112, the first blade clamping slot 113, first fastening screw hole 114, institute It states inner circle Machining of Curved Surface blade 20 to be fastened in first insert pocket, the first blade clamping slot and the first insert pocket connect Logical, the first fastening screw hole is horizontally through the first blade clamping slot, is bolted with the first clamp screw in the first fastening screw hole.It screws First clamp screw, 113 two sidewalls of the first blade clamping slot drive 112 two sidewalls of the first insert pocket in shape is closed up Close up, the first insert pocket 112 clamps the inner circle Machining of Curved Surface blade 20 being fastened in it.To avoid the first blade clamping slot Crackle occurs for 113 root, and the root of the first blade clamping slot is designed to arc-shaped.As an improvement the first insert pocket 112 are inclined in the first knife bar branch 11, are designed in this way, and make two sidewalls and the first blade of the first insert pocket 112 The two sidewalls of clamping slot 113 have larger-size thickness, with improve inner circle Machining of Curved Surface blade 20 it is clamped after intensity and Stability.

Such as Fig. 4, the outer circle Machining of Curved Surface blade 30 is detachably connected with the second knife bar branch 12.Specifically, the second knife Bar branch 12 opens up the second insert pocket 122, the second blade clamping slot 123, second fastening screw hole 124, and the outer round surface adds Work blade 30 is fastened in second insert pocket, and the second blade clamping slot is connected to the second insert pocket, the second fastening spiral shell Hole is horizontally through the second blade clamping slot, is bolted with the second clamp screw in the second fastening screw hole.Second insert pocket The principle of 122 fixed outer circle Machining of Curved Surface blades 30 is identical to the fixed inner circle Machining of Curved Surface blade of first insert pocket 112 20 principle.

In actual production, with reference to Fig. 6, in a work step, outer circle Machining of Curved Surface blade 30 is responsible for processing wheel hub outer circle Curved surface, inner circle Machining of Curved Surface blade 20 are responsible for processing wheel hub end face and interior round surface.In process, the two will not be done It relates to and collides.

The processing combination knife reduces the non-cutting time because of forward and back knife needed for tool changing and tool magazine rotation needs, mentions Labor efficiency has been risen, and has had vacant tool apron for installing other cutters, has improved utilization rate of equipment and installations.

The above content is only the better embodiment of the utility model, for those of ordinary skill in the art, according to this The thought of utility model, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be understood For limitations of the present invention.
