[0041] The rotating seat 2 is rotatably installed on the frame 1, and the top surface of the rotating seat 2 is used for installing an external fixture;

[0042] The driving cylinder 3 is obliquely and rotatably installed on the frame 1, and its output shaft is hinged to the rotating seat 2; The driving cylinder 3 maintains a certain angle with the horizontal plane, so that when the output shaft of the driving cylinder 3 expands and contracts, it can drive the rotating seat 2 to rotate;

[0043] The first limiting component 4 includes a first limiting seat 41 and a first limiting block 42. The first limiting seat 41 is installed on the frame 1; The first limiting block 42 is installed on the rotating seat 2 and is used to abut against the first limiting seat 41 for limiting when the rotating seat 2 rotates to the maximum rotation angle; The distance between the first limiting seat 41 and the vertical plane where the rotation axis of the rotating seat 2 is located can be adjusted to adjust the maximum rotation angle of the rotating seat 2. The first limiting block 42 is connected to the top surface of the rotating seat 2 and does not affect the connection between the external fixture and the rotating seat 2.

[0044] For the flipping device proposed in this embodiment, when the rotating seat 2 rotates to the maximum rotation angle, the first limiting block 42 abuts against the first limiting seat 41 for limiting. The distance between the first limiting seat 41 and the vertical plane where the rotation axis of the rotating seat 2 is located can be adjusted to adjust the maximum rotation angle of the rotating seat 2.

[0047] In some embodiments, the flipping device further includes a second limiting component 5 installed on the frame 1, and the second limiting component 5 is used to limit the initial position of the rotating seat 2. After the rotating seat 2 rotates to the maximum rotation angle and corresponding operations are performed, it needs to be reset to the initial position for the rotation operation of the next external fixture. By using the second limiting component 5 to limit the reset of the rotating seat 2 to the initial position, the stability and reliability of the device can be improved. In this embodiment, at the initial position, the top surface of the rotating seat 2 is parallel to the horizontal plane.

The second limiting block 52 is installed at the bottom of the rotating seat 2 and is used to abut against the first limiting seat 41. By having the second limiting seat 51 and the first limiting seat 41 respectively located on both sides of the rotation axis of the rotating seat 2, and the second limiting block 52 being installed at the bottom of the rotating seat 2, when the rotating seat 2 is in the initial position, the second limiting seat 51 abuts against the second limiting block 52, limiting the reset of the rotating seat 2 to the initial position, which can improve the stability and reliability of the device. In actual design, the surfaces of the second limiting seat 51 and the second limiting block 52 that contact each other are inclined planes, such that the second limiting seat 51 and the second limiting block 52 are in surface contact, improving stability and reliability.

[0049] In some embodiments, a second mounting seat 12 is provided on the frame 1. Multiple groups of second mounting holes 121 are provided on the second mounting seat 12, and second connecting holes 511 matching the second mounting holes 121 are provided on the second limiting seat 51.

For example, a certain inclination angle can be set between the top surface of the rotating seat 2 and the horizontal plane, facilitating the docking of an external fixture to the rotating seat 2, improving convenience.

[0050] In some embodiments, the flipping device further includes a safety locking component 6. The safety locking component 6 includes a first fixing block 61 and a second fixing block 62 that are detachably connected. The first fixing block 61 is installed on the frame 1, and the second fixing block 62 is installed on the rotating seat 2. When the rotating seat 2 is in the initial position, the second fixing block 62 is aligned with the first fixing block 61. A first fixing hole 611 is provided on the first fixing block 61, and a second fixing hole is provided on the second fixing block 62. By installing the first fixing block 61 on the frame 1 and the second fixing block 62 on the rotating seat 2, when the rotating seat 2 is in the initial position, the second fixing block 62 is aligned with the first fixing block 61, that is, the first fixing hole 611 and the second fixing hole are aligned. A connecting pin is inserted into the first fixing hole 611 and the second fixing hole for connection and fixation, so as to prevent the rotating seat 2 from rotating when an external fixture is placed on the rotating seat 2 or during maintenance, and improve the safety and reliability of the device.

[0051] In some embodiments, the safety locking component 6 further includes a third fixing block 63. The third fixing block 63 and the second fixing block 62 are respectively arranged on both sides of the rotating seat 2. When the rotating seat 2 rotates to the maximum angle, the third fixing block 63 is aligned with the first fixing block 61 and can be detachably connected. A third fixing hole 631 is provided on the third fixing block 63. When the rotating seat 2 rotates to the maximum angle, the third fixing block 63 is aligned with the first fixing block 61, that is, the third fixing hole 631 is aligned with the first fixing hole 611. A connecting pin is inserted into the third fixing hole 631 and the first fixing hole 611 for connection and fixation, so as to prevent the rotating seat 2 from being in an inclined state, which causes a large torque on the driving motor and damages the driving motor, and at the same time prevent the first limiting component 4 from failing and causing the rotating seat 2 to rotate, and improve the safety and reliability of the device.

[0052] In some embodiments, the flipping device further includes a proximity component 7. The proximity component 7 includes a first proximity bracket 71 and a first proximity switch 72. The first proximity bracket 71 is installed on the rotating seat 2, and the first proximity switch 72 is installed on the frame 1 for sensing the first proximity bracket 71 in the initial position. By installing the first proximity bracket 71 on the rotating seat 2 and the first proximity switch 72 on the frame 1, when the rotating seat 2 rotates to the initial position, the first proximity switch 72 senses the first proximity bracket 71, and the driving cylinder 3 stops running. At this time, the second limiting seat 51 abuts against the second limiting block 52, so as to prevent the driving cylinder 3 from continuing to move and being damaged after the second limiting block 52 is limited by the second limiting seat 51, and improve the reliability and stability of the device. The first proximity switch 72 used in this embodiment does not involve improvements in programs and algorithms, and uses existing algorithms and principles.

[0053] In some embodiments, the proximity component 7 further includes a second proximity bracket 73 and a second proximity switch 74. The second proximity bracket 73 is installed on the side surface of the first limit block 42, and the second proximity switch 74 is installed on the side surface of the second limit seat 51, and is used to sense the second proximity bracket 73 when the rotating seat 2 rotates to the maximum rotation angle. By installing the second proximity bracket 73 on the side surface of the first limit block 42 and the second proximity switch 74 on the side surface of the second limit seat 51, when the rotating seat 2 rotates to the maximum rotation angle, the second proximity switch 74 senses the second proximity bracket 73, and the driving cylinder 3 stops operating. At this time, the first limit seat 41 abuts against the first limit block 42, preventing the driving cylinder 3 from continuing to move and being damaged after the first limit block 42 is limited by the first limit seat 41, and improving the reliability and stability of the device. The second proximity switch 74 used in this embodiment does not involve improvements in programs and algorithms, and uses existing algorithms and principles.

[0054] In some embodiments, the flipping device further includes a support component 8. The support component 8 includes two bearings 81, two support seats 82 and two support shafts 83.

The support shaft 83 is fixedly connected to the support seat 82 and installed in the bearing 81. By respectively connecting the two support seats 82 to both ends of the top surface of the rotating seat 2, and fixedly connecting the support shaft 83 to the support seat 82 and installing it in the bearing 81, the rotational connection between the rotating seat 2 and the frame 1 is achieved.

[0055] The working principle of this flipping device is as follows: when the rotating seat 2 is in the initial position, an external fixture is installed on the top surface of the rotating seat 2; by extending the driving cylinder 3, the driving cylinder 3 drives the rotating seat 2 to rotate clockwise around the frame 1 until the second proximity switch 74 senses the second proximity bracket 73, and the driving cylinder 3 stops operating. At this time, the first limit seat 41 abuts against the first limit block 42; after the external fixture is removed from the rotating seat 2 after the operation is completed, by contracting the driving cylinder 3, the driving cylinder 3 drives the rotating seat 2 to rotate counterclockwise around the frame 1 until the first proximity switch 72 senses the first proximity bracket 71, and the driving cylinder 3 stops operating. At this time, the second limit seat 51 abuts against the second limit block 52, and returns to the initial position.

[0056] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
