[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Example 1, as Figures 1 to 4 As shown, a coated cutting tool for machining rotors includes a support base 1, a transmission mechanism 2, and a coated cutting tool 3. The support base 1 is fixed on an external machine tool, the transmission mechanism 2 is mounted on the support base 1, and the coated cutting tool 3 is connected to the transmission mechanism 2 and located at the top of the support base 1.
[0021] The transmission mechanism 2 includes a transmission rod 21, a first linkage plate 22, a driven gear 23, a second linkage plate 24, a support rack 25, a tool connecting cylinder 26, and a servo motor 211. The transmission rod 21 is rotatably connected to the support base 1. One end of the first linkage plate 22 is fixed to the transmission rod 21. The driven gear 23 is coaxially rotatably connected to the other end of the first linkage plate 22. One end of the second linkage plate 24 is fixed to the axis of the driven gear 23. The support rack 25 is rotatably connected to the other end of the second linkage plate 24. The tool connecting cylinder 26 is fixed to the top of the support rack 25. The coated tool 3 is disposed inside the tool connecting cylinder 26. The servo motor 211 is fixed to the back of the support base 1, and the output shaft of the servo motor 211 is connected to the transmission rod 21.
[0022] The transmission mechanism 2 also includes a limiting gear ring 27, which is fixed on the side wall of the support base 1 near the driven gear 23, and the tooth groove is provided on the inner wall of the limiting gear ring 27. The driven gear 23 is located inside the limiting gear ring 27 and meshes with the tooth groove of the limiting gear ring 27.
[0023] A driven gear 28 is rotatably connected to the side wall of the support base 1 near the support rack 25. The driven gear 28 meshes with the support rack 25, and two driven gears 28 are symmetrically arranged on both sides of the support rack 25.
[0024] In this invention, the rotor is milled by a coated cutting tool 3. During milling, the transmission rod 21 is driven to rotate by a servo motor 211, which in turn drives the driven gear 23 through the first linkage plate 22, and the driven gear 23 meshes with the limiting gear ring 27. The second linkage plate 24 drives the support rack 25, and the driven gear 28 limits the support rack 25, allowing the support rack 25 to move up and down. By converting curvilinear motion into linear motion, the use of cylinders or other components to drive the coated cutting tool 3 to perform linear reciprocating motion is effectively avoided, thus effectively preventing mechanical fatigue caused by the reciprocating extension and retraction of cylinders.
[0025] Example 2, as Figures 1 to 4 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes:
[0026] A limiting groove 29 is provided through the center of the support rack 25, and a limiting block 210 is fixed at the center of the top of the support base 1. The limiting block 210 is slidably engaged in the limiting groove 29, and the movement direction of the support rack 25 is limited and guided by the limiting block 210 and the limiting groove 29.
[0027] The support base 1 has an L-shaped structure, and a triangular reinforcing plate 4 is fixed at the inflection point of the support base 1. The stability and structural strength of the support base 1 are improved by the reinforcing plate 4.
[0028] A threaded hole is provided through the side wall of the tool connecting cylinder 26, and a screw is screwed into the threaded hole. The coated tool 3 is detachably connected to the tool connecting cylinder 26 by the screw, so that the coated tool 3 can be quickly disassembled and assembled.
[0029] When using the coated cutting tool, first fix the support base 1 in an appropriate position on the machine tool, then connect the coated cutting tool 3 inside the cutting tool connecting cylinder 26, and then mill the rotor through the coated cutting tool 3. During the machining process, the servo motor 211 drives the transmission rod 21 to rotate, which in turn drives the driven gear 23 through the first linkage plate 22, and makes the driven gear 23 mesh with the limiting gear ring 27. Then, the second linkage plate 24 drives the support rack 25 to move, and the driven gear 28 limits the support rack 25, so that the support rack 25 can move up and down.
