During the rotation, the screw drives the threaded seat to move in the direction close to the motor three. While the threaded seat moves, it drives the transmission frame through the connecting member, so that the transmission frame rotates with the connection with the connecting frame as the center of the circle. While the connecting frame rotates, it drives the clamping member to move, so that the two clamping members are close to each other, so that the two clamping members clamp the motor shaft through the inner arc-shaped clamping groove. The arc-shaped clamping groove can increase the contact area between the clamping member and the motor shaft, so that the two clamping members can stably clamp the motor shaft without causing wear to the surface of the motor shaft; after the clamping device clamps the motor shaft, the vertical linear module drives the clamping device to move vertically, so that the clamping device moves to a height corresponding to the rectangular channel of the bottom plate, so that the clamping device and the motor shaft can move normally through the bottom plate to the rotating assembly; finally, the horizontal linear module drives the vertical linear module and the clamping device to move in the direction of the rotating assembly, so that the motor shaft moves to the bottom of the rotating assembly;

At the same time, the vertical linear module, the horizontal linear module and the clamping device can continuously transport the motor shaft, thereby increasing the efficiency of the motor shaft milling work;

[0020] In the present invention, after the pneumatic chuck clamps the motor shaft, the motor four drives the screw rod two to rotate. During the rotation process, the screw rod two drives the moving platform to move horizontally, allowing the moving platform to slide along the track of the slide rail two. The slide rail two plays a role in supporting the moving platform and makes the moving platform more stable during movement, thereby preventing the moving platform and the milling groove assembly from shaking. When the moving platform moves horizontally, the roller will push the rotating part when it moves to the rotating part, allowing the rotating part to rotate toward the side away from the roller with the connecting shaft as the center of the circle. During the rotation process of the rotating part, the pneumatic chuck and the motor shaft are driven to rotate synchronously. When the roller pushes the rotating part, the cylinder under the rotating frame Push the rotating frame to rotate in a circle with the connection with the storage table. The rotating frame drives the roller to rise while rotating, so that the roller can push the rotating part to rotate above the storage table. Then the rotating part continues to rotate under the action of its own weight and the weight of the pneumatic chuck and the motor shaft until the rotating part rotates 180° to become an inverted T shape, and the top of the storage table is flush with the bottom of the rotating part at this time. The rotating part will fit with the top of the storage table. The storage table supports the rotating part and restricts the rotating part to prevent it from rotating randomly. With the support of the storage table, the rotating part remains stable and no longer rotates.

[0021] In the present invention, after the rotating part rotates 180° and stabilizes on the storage table, the moving platform no longer moves, and at the same time, motor one drives screw rod one to rotate, and when screw rod one rotates, it drives the slide seat to move down, and the slide seat synchronously drives the fixed part and motor two to move down, so that the milling cutter connected to motor two moves to the motor shaft, and then motor two drives the milling cutter to rotate quickly, so that the milling cutter performs groove milling on the motor shaft; when the milling cutter performs groove milling on the motor shaft, the pneumatic chuck can keep the motor shaft stable to prevent the motor shaft from shaking or shifting, and the storage table prevents the pneumatic chuck and the rotating part from shifting, so that the groove milling work of the motor shaft can be carried out normally; after the groove milling work is completed, the storage table continues to move, and as the storage table is The table no longer supports the rotating part, and the rotating part automatically rotates under the action of gravity and allows the pneumatic chuck and the motor shaft to rotate to the initial position; then the horizontal linear module drives the clamping device to clamp the motor shaft that has been processed on the pneumatic chuck and move it out of the housing. After the staff takes away the processed motor shaft, they place the unprocessed motor shaft on the clamping device, and let the clamping device place the motor shaft on the pneumatic chuck again, thereby realizing uninterrupted transportation of the motor shaft; rollers are provided on both sides of the storage table, so that the storage table can push the rotating part to rotate during the reciprocating motion, reducing the interval time for the milling assembly to mill the motor shaft, thereby further increasing the efficiency of the motor shaft milling work.
