In summary, in the numerical control machine tool with multiple cutters and the switching method, the resistance ring 605 and the pull rope 607 are used in cooperation, so that in the process of switching the milling cutter 502 when the housing 501 rotates, the resistance ring 605 rotates along with the rotation of the housing 501, and the first counterweight ball 603 in the roller 601 increases the rotation resistance of the roller 601, so that the pull rope 607 cannot pull the roller 601 to rotate, the pull rope 607 can only pull the second counterweight ball 610 and the guide rod, so as to pull the connecting rod 503 to move towards the inner wall of the housing 501, so that the milling cutter 502 initially positioned at the bottom end of the housing 501 is retracted into the inner wall of the housing 501 along with the rotation of the housing 501, and as the housing 501 rotates, when the pulling force of the pull rope 607 is greater than the resistance of the roller 601, the roller 601 can be driven to rotate, so as to extrude the fixture block 602 and the extrusion block 509, and when the pulling force of the pull rope 607 is greater than the friction force between the fixture 602 and the extrusion block 509, the extrusion block 509 enters the bottom frame 507, so that the fixture block 602 is extruded with another extrusion block 509, and therefore the pulling rope 607 is kept in a tight state all the time, the situation that the pulling rope 607 is broken due to the rotation of the milling cutter 502 along with the shell 501 and the milling cutter 502 is kept to be positioned on the inner wall of the shell 501 all the time is avoided, when the milling cutter 502 is used and is about to rotate to the bottom end of the shell 501, the extrusion block 509 is not arranged at the lower right corner of the inner ring 510, the milling cutter 502 descends under the action of the gravity of the second counterweight ball 610 to pull the pulling rope 607 so as to pull the rotating roller 601 to rotate, the distance from the fixture block 602 to the next extrusion block 509 increases at the moment, so that the pulling rope 607 is loosened, the milling cutter 502 leaks out of the inner cavity of the shell 501, the circle centers of the curved hole 504 and the semicircular groove 505 are positioned at the same center, the sliding block 506 swings into the curved hole 504 by the gravity, so as to limit the movement of the connecting rod 503, and achieve the effect that the milling cutter 502 is fixed, thus, the turning and milling work is carried out.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
