Further, it should be noted that this specification describes many features. Although some features may be combined to show a possible system design, these features may also be used in other combinations not explicitly described. Thus, the combinations illustrated are not intended to be limiting unless otherwise specified.
The principles of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.
The embodiment of figures 1-4 discloses a tool holder head which is entirely square, and the body of the tool holder head is provided with a tool mounting part 1, an air injection channel 2 and a tool holder mounting hole 4;
the tool mounting part 1 is used for mounting a tool 100, and the tool 100 is used for grooving the flange 200; a cutting part 110 is arranged at the tool tip of the tool 100, when the groove is opened, the flange 200 rotates under the action of the feeding mechanism and moves to one side of the tool 100, and the cutting part 110 cuts an annular groove on the surface of the flange 200;
the air injection channel 2 is used for air injection impurity removal, when the cutting part 110 is grooved, the air injection channel 2 sprays an air column to the tool nose position, and scrap iron and other impurity waste materials generated by grooving are synchronously cleaned;
the cutter bar mounting hole 4 is used for mounting a cutter bar, and a screw hole is formed in the side surface of the cutter bar mounting hole 4 and used for mounting a locking screw for fixing the cutter bar; the cutter 100 is connected and fixed with the machine tool through a cutter head and a cutter rod.
In this embodiment, the air injection channel 2 is arranged in the body of the cutter head and comprises a flow guide section 21 and an air inlet section 22 which are communicated with each other;
the flow guide section 21 is a straight hole extending to the tool tip position and is mainly used for guiding the direction of the airflow.
In the embodiment, for convenience of installation and avoidance of disturbance to the air pipe caused by the machine tool during working, the air inlet section 22 is connected with the air pipe through the rotatable joint 5;
as shown in fig. 3-4, the air inlet section 22 is provided with internal threads, one end of the rotatable joint 5 provided with external threads is sleeved in the air inlet section 22, the other end is connected with an air pipe, and compressed air is conveyed to the air injection channel 2 through the air pipe;
in this embodiment, the aperture of the air inlet section 22 is larger than the aperture of the flow guide section 21, as shown in fig. 4, after the rotatable joint 5 is connected to the air inlet section 22, a flow guide section remains, and the remaining flow guide section partially forms the pressurizing cavity 3, so that the pressure of the impurity-removed air column can be further increased, the speed of the air in the flow guide section 21 can be increased, and the impurity removal effect can be improved;
in order to ensure sufficient gas pressure, the diameter of the flow guide section 21 is not more than 2 mm.
When grooving, the machine tool ejects the cutting fluid to the flange 200. In order to avoid mutual interference between cutting fluid spraying and air injection impurity removal, an air flow valve 6 is further installed at the air inlet end of the rotatable connector 5, and the throttle valve 6 is used for controlling on-off of air flow, so that the cutting fluid spraying and the air injection impurity removal are alternately performed.
The fluting in-process, the iron fillings of card in the ring channel are difficult to the clearance, in order to improve the clear useless efficiency of gas column, following scheme has been taken to this embodiment:
the cutting part 110 is in a flat sheet shape, an air column sprayed out from the air spraying channel 2 is positioned on an extending surface of the cutting part 110, the plane is vertical to a processing surface of a workpiece (namely a flange) and is tangent to a processed annular groove, and the air column can directly clean scrap iron on two sides of the cutting part 110;
as the flange 100 rotates and the flange 100 gradually moves to one side of the cutter 100, the annular groove gradually deepens, the same position of the annular groove needs to be cut by multiple wheels of the cutter 100, when scrap iron is clamped in the semi-finished annular groove, the scrap iron can generate large abrasion to the cutter, and in order to solve the problem, the air column is positioned at one side of the cutter in cutting operation, namely the air jet 211 is positioned at one side of the cutter provided with a cutting part; after the air column is separated from the air injection channel 2, the air column inevitably diffuses to the periphery gradually, and finally, when the air column is contacted with the flange and the cutting part, the cutting part 110 blows out scrap iron in the groove of the passing annular groove, so that the cutting part 110 is prevented from being worn due to the scrap iron;
in order to further improve the effect of cleaning the iron filings, the included angle range of the air column and the workpiece processing surface is 30-40 degrees, and tests prove that the optimal angle is 35 degrees, namely when the included angle between the axis extension line of the flow guide section 21 and the flange 200 is 35 degrees, the iron filings cleaning effect is optimal.
The utility model also provides a flange, and an annular groove of the flange is processed by adopting the cutter bar head described in any embodiment.
