[0020] During implementation, the rotating assembly 3 is supported by the bracket assembly 2. When the bracket assembly 2 is implemented, it is supported by the motor mounting plate 21, the left shaft support plate 23 and the right shaft support plate 24. When supporting, the motor mounting plate 21, the left shaft support plate 23 and the right shaft support plate 24 are connected into one by the connecting plate 22, and at the same time cooperate with the support of the support block 25, thereby increasing the stability of the clamping rotating mechanism during operation and avoiding the shaking phenomenon that occurs when the clamping rotating mechanism is used.

[0021] Furthermore, if Figure 2 as well as Figure 3 As shown, a rotating assembly 3 is installed at the top of the bracket assembly 2, and the rotating assembly 3 is used to drive the rotation work. The rotating assembly 3 is composed of a servo motor 31, a coupling 32 and a rotating shaft rod 33. The servo motor 31 is fixedly connected to the surface of the motor mounting plate 21 by screws, and the output end of the servo motor 31 passes through the motor mounting plate 21 and is installed with a coupling 32. The rotating shaft rod 33 is installed between the left support plate 23 of the shaft rod and the right support plate 24 of the shaft rod through a bearing, and one end of the rotating shaft rod 33 is fixedly connected to the surface of the coupling 32, and the other end of the rotating shaft rod 33 passes through the right support plate 24 of the shaft rod and is supported by the support block 25.

[0022] When the rotating assembly 3 is implemented, the servo motor 31 drives the rotating shaft 33 to rotate under the action of the coupling 32 .

[0023] Furthermore, if Figure 2 as well as Figure 4 As shown, the surface of the rotating component 3 is connected to a clamping component 4, which is used for clamping hinge parts. The clamping component 4 includes a cylinder mounting frame 41, a clamping cylinder 42 and a clamping claw 43.

[0024] When the clamping assembly 4 is implemented, the clamping cylinder 42 on the surface of the cylinder mounting frame 41 drives the clamping claw 43 to move, thereby clamping the hinge part.

[0025] Furthermore, if Figure 2 as well as Figure 3As shown, a sensing component 5 is also provided between the rotating component 3 and the bracket component 2, and the sensing component 5 is used for sensing work when the rotating component 3 rotates. The sensing component 5 includes a photoelectric switch 51, a fixing block 52 and a sensing sheet 53. The photoelectric switch 51 is fixed on the surface of the rotating shaft rod 33, and the fixing block 52 is fixedly connected to the surface of the right support plate 24 of the shaft rod by bolts, and a sensing sheet 53 is installed on the top of the fixing block 52, and the sensing sheet 53 cooperates with the photoelectric switch 51 for sensing work when the rotating shaft rod 33 rotates.

[0026] When the sensing assembly 5 is implemented, the rotation of the shaft rod 33 drives the photoelectric switch 51 to rotate. When the photoelectric switch 51 rotates, it cooperates with the sensing sheet 53 at the top of the fixed block 52 to realize the sensing work of the rotation angle, thereby improving the accuracy of the rotation position.

[0027] Working principle: When in use, the rotating assembly 3 is supported by the bracket assembly 2. When the bracket assembly 2 is implemented, it is supported by the motor mounting plate 21, the left support plate 23 of the shaft and the right support plate 24 of the shaft. When supporting, the motor mounting plate 21, the left support plate 23 of the shaft and the right support plate 24 of the shaft are connected into one by the connecting plate 22, and at the same time cooperate with the support of the support block 25, thereby increasing the stability of the clamping rotating mechanism during operation and avoiding the shaking phenomenon that occurs when the clamping rotating mechanism is used.

[0028] When the clamping and rotating mechanism is working, it is first clamped by the clamping component 4. When the clamping component 4 is implemented, the clamping claw 43 is driven to move by the clamping cylinder 42 on the surface of the cylinder mounting frame 41, so as to clamp the hinge part; then it is rotated by the rotating component 3. When the rotating component 3 is implemented, the servo motor 31 drives the shaft rod 33 to rotate under the action of the coupling 32. During the rotation, the rotation angle is sensed by the sensing component 5. When the sensing component 5 is implemented, the rotation of the shaft rod 33 will drive the photoelectric switch 51 to rotate. When the photoelectric switch 51 rotates, it will cooperate with the sensing sheet 53 at the top of the fixed block 52 to realize the sensing of the rotation angle, thereby improving the accuracy of the rotation position and finally completing the use of the automatic clamping and rotating mechanism.
