DETAILED DESCRIPTION

[0016] Embodiments of the present utility model: Figures 1 to 5As shown, an automatic turning device for a motor rotor comprises a workbench 1, on which a feeding mechanism, a feeding mechanism, a tool assembly 17, a gripping device, and a rotor driving mechanism are provided. The feeding mechanism and the feeding mechanism are respectively a guide rail 1 2 and a guide rail 2 3 which are arranged obliquely. A stopper 4 is provided at the lower position of the guide rail 1 2. The rotor to be turned is arranged on the guide rail 1 2 and automatically slides from a high position to a low position. The stopper 4 blocks it and makes it stay at a fixed position. The rotor driving mechanism comprises a bracket 5 and a driving device. The bracket 5 has a positioning mechanism matched with a rotor 6. The positioning mechanism comprises a pair of positioning members 7 and two pairs of support wheels 8 which are V-shaped and transferred to the bracket 5. The two pairs of support wheels 8 which are V-shaped and respectively rotate the rotor shaft located at the two ends of the rotor 6. Support and limit both sides of the rotor 6, a pair of positioning members 7 limit both ends of the rotor shaft of the rotor 6 to prevent the rotor from moving axially, so that the rotor 6 is placed horizontally at a fixed position on the bracket 1 and can rotate along its own axis. The tool assembly 17 and the driving device are arranged on both sides of the bracket 1. The driving device includes a conveyor 9 and a driving mechanism. The conveyor has a circular conveying conveyor belt 10. The conveyor belt 10 is made of elastic materials such as rubber. The driving mechanism can drive the conveyor 9 to rotate. When working, when the conveyor 9 rotates downward, the conveyor belt 10 is tilted and pressed down on the outer surface of the rotor 6. Under the action of friction, the conveyor belt 10 drives the rotor 6 to rotate through a circular transmission. The tool assembly 17 on the other side turns the outer surface of the rotor 6. After turning, The conveyor 9 rotates upward to separate the conveyor belt 10 from the rotor 6. Since the conveyor belt 10 has good elasticity, the accuracy requirement of the rotation angle of the conveyor 9 can be reduced. The conveyor belt 10 can deform itself to press the outer surface of the rotor 6, and the conveyor belt 10 is tilted downward on the outer surface of the rotor 6 to limit the rotor 6 in the up and down directions. In conjunction with the V-shaped support wheels 8 and the positioning member 7, the positioning placement and stable rotation of the rotor 6 are achieved to complete the turning operation. The feeding mechanism is an inclined guide rail 2 3. The guide rail 1 2, the bracket 5, and the guide rail 2 3 are distributed at the same interval along the X-axis. The grabbing device is located above the bracket 5 and includes an XY platform 11 and a pair of clamps 12. The XY platform 11 is a prior art that drives a pair of clamps 12 along the X-axis , and moves in the Y-axis direction. The fixture 12 is a claw cylinder, which clamps and releases the rotor 6 by extending and retracting the cylinder body. The spacing between the two fixtures 12 along the X-axis is the same as the spacing between the guide rail 1, the bracket 5, and the guide rail 2 3 along the X-axis. When working, the fixture 12 moves through the XY platform. When one of the fixtures 12 is located on the guide rail 2 to grab the rotor 6 to be turned, the other fixture 12 is just located on the bracket 5 to grab the turned rotor 6. When the XY platform drives the fixture 12 to move and transfers the rotor 6 to be turned on the guide rail 2 to the bracket 5, the turned rotor 6 on the bracket 5 is synchronously transferred to the guide rail 2 3 for output. Then the fixture 12 is reset by moving the XY platform and repeats the above actions to realize the rapid and automatic transportation of the rotor 6.

[0017] As a preferred embodiment, guide rail 2 3 and guide rail 1 2 both include a pair of rails 13 slidably connected to the workbench 1, and a double-headed screw 14 is spirally connected to the pair of rails 13. The double-headed screw 14 is rotated to move the pair of rails 13 toward each other or relatively to each other to adjust the spacing to accommodate the transportation of rotors 6 of different specifications.

[0018] As a preferred embodiment, a chip discharge port 15 is provided on the workbench 1, and the chip discharge port 15 is located below the bracket 1. A chip baffle 16 is provided around the chip discharge port 15 to facilitate the discharge of the chips cut from turning.
