All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0029] Please see Figures 1-8 This utility model provides an embodiment of a grinding fixture for a high-speed motor rotor, comprising a base 1 and a turntable 2. The turntable 2 is disposed on the outside of the base 1, and four sets of gimbals 3 are disposed on the outside of the turntable 2 at equal intervals. A flip plate 4 is movably mounted on the outside of each gimbal 3. A circular bracket 5 is symmetrically mounted on the top of each flip plate 4. A servo motor 6 is mounted on the top of each turntable 2 below the gimbal 3. A rotating shaft 10 is mounted on the output end of each servo motor 6. A small gear 7 is mounted on the side of the rotating shaft 10 away from the servo motor 6. A large gear 8 is mounted at the center of the bottom of each gimbal 3. The large gear 8 meshes with the small gear 7. A second annular groove 24 is provided at the bottom of each gimbal 3 outside the large gear 8. Eight sets of first sliding columns 9 are slidably connected to the top of each turntable 2 outside the servo motor 6. Three sets of second cylinders 15 are slidably mounted on the side wall of the circular bracket 5.
[0030] The output end of the second cylinder 15 is equipped with a push rod 22, and the push rod 22 extends through the circular bracket 5 and into the interior of the circular bracket 5.
[0031] A U-shaped frame 23 is installed at one end of the push rod 22 inside the circular bracket 5, and a hub motor wheel 16 is movably installed inside the U-shaped frame 23;
[0032] When using the grinding fixture, the second cylinder 15 is opened. Supported by the circular bracket 5, the second cylinder 15 drives the push rod 22 to move outward. The push rod 22 drives the U-shaped frame 23 and the hub motor wheel 16 to move outward, placing the rotor to be ground between the two sets of circular brackets 5. The second cylinder 15 is then opened in the opposite direction, causing the push rod 22 to drive the U-shaped frame 23 and the hub motor wheel 16 to clamp the rotor in the center. When the rotor needs to be rotated for grinding, the multiple sets of hub motor wheels 16 are rotated. Under the rotation of the hub motor wheels 16, the hub motor wheels 16 drive the rotor to rotate for grinding. The servo motor 6 is then activated, and the rotor rotates for grinding on the turntable 2. With the servo motor 6 supporting the rotation, the rotating shaft 10 rotates, and the rotating shaft 10 drives the small gear 7 to rotate. Under the meshing of the small gear 7 and the large gear 8, the small gear 7 drives the large gear 8 to rotate. Under the sliding support of the first sliding column 9 and the second annular groove 24, the large gear 8 drives the gimbal 3, the flip plate 4, the circular bracket 5, and the rotor to rotate circumferentially around the large gear 8 as the axis. This facilitates the convenient rotation position of the grinding fixture to adapt to the grinding machine for grinding operations. It achieves stable central clamping and positioning of the rotor by the grinding fixture, facilitates convenient rotation and adjustment of the rotor's position, and facilitates rapid rotation position adaptation to the grinding machine for grinding operations.
[0033] A stepper motor 19 is installed at the top of the base 1, a gear transmission assembly 20 is installed at the output end of the stepper motor 19, and a support shaft 21 is installed at the center of the bottom end of the turntable 2.
[0034] The support shaft 21 is connected to the gear transmission assembly 20, and the bottom end of the outer turntable 2 of the support shaft 21 is provided with a first annular groove 18;
[0035] The top of the outer base 1 of the stepper motor 19 is symmetrically equipped with a second sliding column 17, and the second sliding column 17 is slidably connected to the first annular groove 18;
[0036] After a set of rotors has been polished, the stepper motor 19 is turned on. With the support of the base 1, the stepper motor 19 drives the gear transmission assembly 20 to rotate. The gear transmission assembly 20 drives the support shaft 21 to rotate. The support shaft 21 drives the turntable 2 and multiple sets of gimbals 3 to rotate. The second sliding column 17 provides sliding support to the first annular groove 18, so that the polished set of rotors moves to one side and the rotors to be polished move to the polishing area for polishing. This facilitates convenient rotation and polishing operations between multiple sets of rotors, realizes the circumferential rotation of the polishing fixture to polish multiple sets of rotors in sequence, shortens the conversion speed between each set of rotors, and improves the efficiency of the polishing fixture for batch polishing of rotors.
[0037] The gimbal 3 has a first axis 11 symmetrically and movably mounted on its side wall. The surface of the first axis 11 is fitted with a first cylinder 12. The output end of the first cylinder 12 is movably mounted with a second axis 13.
[0038] A third shaft 14 is movably mounted on one side of the flip plate 4. The flip plate 4 is movably connected to the gimbal 3 through the third shaft 14. The side of the flip plate 4 away from the third shaft 14 is movably connected to the first cylinder 12 through the second shaft 13.
[0039] When angled grinding is required, the first cylinder 12 is opened. Supported by the first shaft 11, the first cylinder 12 drives the second shaft 13 to rotate. The second shaft 13 drives the flipping plate 4 to rotate around the third shaft 14. The flipping plate 4 drives the circular bracket 5 and the rotor to rotate at different angles, which facilitates grinding at different angles of the rotor. This enables grinding at multiple angles of the grinding fixture and improves the convenience of multi-angle rotation of the grinding fixture.
[0040] Working principle: When using the grinding fixture, the second cylinder 15 drives the push rod 22 to move outward. The push rod 22 drives the U-shaped frame 23 and the hub motor wheel 16 to move outward, placing the rotor to be ground between the two sets of circular supports 5. The second cylinder 15 is then opened in the opposite direction, causing the push rod 22 to drive the U-shaped frame 23 and the hub motor wheel 16 to clamp the rotor in the center. When the rotor needs to be rotated for grinding, the multiple sets of hub motor wheels 16 rotate. Under the rotation of the hub motor wheels 16, the hub motor wheels 16 drive the rotor to rotate for grinding. The servo motor 6 drives the rotating shaft 10 to rotate, which in turn drives the small gear 7 to rotate. The small gear 7 drives the large gear 8 to rotate, which in turn drives the gimbal 3, the tilting plate 4, the circular support 5, and the rotor to rotate circumferentially around the large gear 8. The rotating mechanism facilitates convenient rotation of the grinding fixture to adapt to the grinding machine for grinding operations. Stepper motor 19 drives gear transmission assembly 20 to rotate, which in turn drives support shaft 21 to rotate. Support shaft 21 drives turntable 2 and multiple gimbals 3 to rotate. Second sliding column 17 provides sliding support to first annular groove 18, allowing one set of rotors that has been ground to move to one side, and the rotor to be ground to move to the grinding area for grinding. This facilitates convenient rotation and grinding operations between multiple sets of rotors. First cylinder 12 drives second shaft 13 to rotate, which in turn drives flip plate 4 to rotate around third shaft 14. Flip plate 4 drives circular bracket 5 and rotor to rotate at different angles, facilitating grinding at different angles of rotor rotation, thus completing the use of the grinding fixture.
