[0025] Example

[0026] To address the problem that existing rotor core grinding equipment requires manual reversal of the rotor core before grinding its two output shafts sequentially, which is cumbersome, increases the labor intensity of operators, and fails to improve work efficiency, this paper refers to... Figure 1 and Figure 2 As shown, this application discloses a rotor core output shaft grinding machine, including a machine base 10, a rotating clamping mechanism 20, a grinding mechanism 30 and a reversing mechanism 40;

[0027] A blind slot 11 is provided in the upper center of the machine tool;

[0028] The rotating clamping mechanism includes a first telescopic drive assembly 21 disposed on one side of the machine tool in the first direction, a rotating clamping assembly 22 disposed above the first telescopic drive assembly, a second telescopic drive assembly 23 disposed on the other side of the machine tool in the first direction, and a top assembly 24 connected above the second telescopic drive assembly and directly opposite the rotating clamping assembly.

[0029] The grinding mechanism includes a third telescopic drive assembly 31 disposed on one side of the machine tool in the second direction and a grinding assembly 32 disposed on the third telescopic drive assembly;

[0030] The reversing mechanism includes a lifting drive assembly 41 located below the blind slot and at the bottom of the machine, a rotating platform 42 connected to the lifting drive assembly inside the blind slot, and a flipping clamping assembly 43 located on the rotating platform.

[0031] In the specific implementation process, the lifting drive assembly drives the rotating platform to rise, and the operator places the rotor core to be processed on the rotating platform. Then, the first and second telescopic drive assemblies drive the rotating clamping assembly and the tip assembly to move towards each other to clamp the rotor core. After that, the lifting drive assembly drives the rotating platform to reset, and the third telescopic drive assembly drives the grinding assembly to extend and make the rotating clamping assembly cooperate with the tip assembly to drive the rotor core to rotate, so that the grinding assembly grinds one end of the rotor core's output shaft. After the grinding of one end of the rotor core is completed, the third telescopic drive assembly drives the grinding assembly to reset, and the lifting drive assembly drives the rotating platform to rise again to support the rotor core. The first and second telescopic drive assemblies drive the rotating clamping assembly and the tip assembly to move away from the rotor core. At this time, the flipping clamping assembly clamps the rotor core, and the rotating platform rotates 180° to reverse the output shafts at both ends of the rotor core. After this action is completed, the flipping clamping assembly resets, and the other end of the rotor core is ground according to the above operation steps.

[0032] In one specific embodiment, the rotary clamping assembly of this application includes a first power motor 221 and a pneumatic chuck 222. The output shaft of the first power motor is connected to the pneumatic chuck. In a specific embodiment, the operator inserts the output shaft of the rotor core into the pneumatic chuck. When the first power motor drives the pneumatic chuck to rotate, the rotor core can rotate.

[0033] In one specific implementation, the first telescopic drive assembly and the second telescopic drive assembly of this application have the same structure. The first telescopic drive assembly includes a first servo screw module 211, a first linear guide rail 212, and a first sliding plate 213. The first servo screw module and the first linear guide rail are arranged side by side on the machine base. The first sliding plate is connected to the first servo screw module and the first linear guide rail. Under the drive of the first servo screw module and the first linear guide rail, the first sliding plate will move. Based on this principle, the rotary clamping assembly provided on the first telescopic drive assembly can move telescopically, and the top tip assembly provided on the second telescopic drive assembly can move telescopically.

[0034] In one specific embodiment, the tip assembly of this application includes a fixed box 241, a bearing seat 242, and a tip body 243. The fixed box is connected to the second telescopic drive assembly. The bearing seat is located on one side of the fixed box, facing the pneumatic chuck. The tip body is rotatably inserted into the bearing seat. When the rotary drive assembly drives the rotor core to rotate, the tip body will rotate on the bearing seat. In this way, the grinding assembly can smoothly grind the output shaft of the rotor core.

[0035] Similar to the first and second telescopic drive components, the third telescopic drive component of this application includes a second servo screw module 311, a second linear guide rail 312, and a second sliding plate 313. The second servo screw module and the second linear guide rail are arranged side by side on a third-direction side of the machine tool. The second sliding plate is connected to the second servo screw module and the second linear guide rail. Under the cooperative drive of the first servo screw module and the second linear guide rail, the second sliding plate can extend and retract. In this way, the grinding component of this application can contact or move away from the rotor core.

[0036] In one specific embodiment, the grinding assembly of this application includes a base 321, a second power motor 323, and a grinding wheel 322. The base is disposed on a second sliding plate, and an installation groove 3211 is provided inside the base. The grinding wheel is rotatably connected to the installation groove via a rotating shaft. The second power motor is disposed on one side of the base and its output shaft is connected to the rotating shaft. When the second power motor drives the grinding wheel to rotate, the grinding wheel can grind the output shaft of the rotor core.

[0037] In one specific embodiment, the lifting drive assembly of this application includes a first cylinder 411 and a lifting plate 412. The first cylinder is located at the bottom of the machine base, and the lifting plate is connected to the piston rod of the first cylinder inside the blind slot. When the first cylinder drives the lifting plate to lift, the rotating support of this application can support the rotor core or separate it from the rotor core.

[0038] In one specific embodiment, the rotating platform includes a rotating cylinder 421 and a platform body 422. The rotating cylinder is located above the lifting plate, and the platform body is connected to the output shaft of the rotating cylinder. A cross-shaped groove 4221 for placing the rotor core is provided on the top of the platform body. Driven by the rotating cylinder, the platform body of this application can rotate 180°. In this way, the positions of the two output shafts of the rotor core can be reversed, so that the grinding assembly can grind the two output shafts of the rotor core sequentially.

[0039] In one specific embodiment, the flipping clamping assembly of this application includes a hinge block 431, a second cylinder 434, an inverted L-shaped clamping arm 432, and a clamping block 435. The hinge block is integrally disposed on one side of the support body and is set higher than the support body. A hinge groove is provided above the hinge block, and sickle-shaped grooves 4311 are correspondingly opened on opposite sides of the hinge groove. The vertical part of the inverted L-shaped clamping arm is disposed in the hinge groove, and two positioning posts 433 are respectively provided on both sides of the arm and inserted into the sickle-shaped grooves. The second cylinder 434... The cylinder is located at the bottom of the hinge block and its piston rod passes through the hinge block and connects to the vertical part of the inverted L-shaped clamping arm. The clamping block is located below the free end of the horizontal part of the inverted L-shaped clamping arm, and a trapezoidal groove 4351 is opened at the bottom of the clamping block. When the rotor core is placed on the support body, the second cylinder will drive the inverted L-shaped clamping arm to descend. At this time, the four positioning pins on the inverted L-shaped clamping arm will move in the two sickle-shaped grooves, and the clamping block at the bottom of the inverted L-shaped clamping arm can clamp the rotor core through the trapezoidal groove.
