[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-3 A flipping mechanism for reworking auto body parts includes a base 1 and a rotating bracket 2. The rotating bracket 2 is provided with a first clamping plate 21 and a second clamping plate 22, which work together to clamp the auto body part. The rotating bracket 2 is rotatably connected to the base 1 via a rotating shaft 9. A support frame 14 is fixedly mounted on the base 1, and a bearing 5 is provided on the support frame 14. The support frame 14 is rotatably connected to the rotating shaft 9 via the bearing 5. Workers can easily flip the rotating bracket 2, saving effort and time.

[0022] Furthermore, a limiting plate 3 is provided on both sides of the base 1. The limiting plate 3 is also rotatably connected to the base 1 via a rotating shaft 9, and the limiting plate 3 is fixedly connected to the rotating bracket 2. A first limiting groove 31 and a second limiting groove 32 are provided on the limiting plate 3. A limiting rod 5 is provided on the base 1 and is slidably connected to the base 1 in the vertical direction. A limiting block 4 is provided on the top of the limiting rod 5. The limiting block 4 enters the limiting groove of the limiting plate 3 to limit the rotating bracket 2. When the limiting block 4 is located in the first limiting groove 31, the rotating bracket 2 is arranged vertically, referring to Figure 1 When the limiting block 4 is located in the second limiting groove 32 , the rotating bracket 2 is arranged horizontally.

[0023] refer to Figure 1 and Figure 2 The limiting rod 5 is provided with a first fixing plate 52, a first elastic member 51, a first sliding sleeve 53, and a first limiting seat 10 in order from top to bottom. The first fixing plate 52 is fixedly connected to the limiting rod 5. The first elastic member 51, the first sliding sleeve 53, and the first limiting seat 10 are respectively sleeved on the outside of the limiting rod 5. The first elastic member 51 is fixedly connected to the first fixing plate 52 and the first sliding sleeve 53 respectively. The first sliding sleeve 53 and the first limiting seat 10 are slidably connected to the limiting rod 5. The first limiting seat 10 is fixedly connected to the base 1. A pedal 13 is provided at the bottom of the limiting rod 5. One end of the pedal 13 is rotatably connected to the base 1 via the support 12. The two ends of the pedal 13 are rotatably connected to the bottom of the limiting rod 5. The first elastic member 51 is used to support the limiting rod 5 so that the limiting block 4 at the top of the limiting rod 5 can be inserted into the limiting groove of the limiting plate 3.

[0024] When the staff steps on the pedal 13, the pedal 13 rotates relative to the support 12, and the pedal 13 can pull the limit rod 5 downward, the first elastic member 51 is compressed, and the limit block 4 on the top of the limit rod 5 leaves the second limit groove 32 of the limit plate 3. At this time, the staff can manually flip the rotating bracket 2 to complete the flipping of the body parts. When the first limit groove 31 of the limit plate 3 comes to the top of the limit block 4, release the pedal 13, and the first elastic member 51 pushes the limit rod 5 upward. The limit block 4 can be inserted into the first limit groove 31 of the limit plate 3 to complete the limiting of the rotating bracket 2.

[0025] refer to Figure 1-3 The base 1 is also provided with a friction plate 6 and a friction wheel 7. The friction plate 6 is arranged parallel to the limit plate 3. The friction wheel 7 contacts the side surface of the friction plate 6 to generate contact friction. The friction plate 6 is fixedly connected to the base 1. The friction wheel 7 is connected to the first end of a friction rod 8. The second end of the friction rod 8 is rotatably connected to one end of a rocker 84. The other end of the rocker 84 is rotatably connected to a connecting bracket 85. The connecting bracket 85 is fixedly connected to the rotating bracket 2.

[0026] refer to Figure 1 and Figure 3 A second fixed plate 82, a second elastic member 81, a second sliding sleeve 83 and a second limiting seat 11 are sequentially arranged between the first end and the second end of the friction rod 8. The second fixed plate 82 is fixedly connected to the friction rod 8. The second elastic member 81, the second sliding sleeve 83 and the second limiting seat 11 are respectively sleeved on the outside of the limiting rod 5. The second elastic member 81 is fixedly connected to the second fixed plate 82 and the second sliding 83 respectively. The second sliding sleeve 83 and the second limiting seat 11 are slidably connected to the friction rod 8, and the second limiting seat 11 is fixedly connected to the rotating bracket 2.

[0027] When the staff is flipping the rotating bracket 2, the second elastic member 81 is used to apply pressure to the friction rod 8, and the friction plate 6 and the friction wheel 7 always maintain contact, forming a friction force. This friction force can limit the rotation speed of the rotating bracket 2. During the flipping process, the staff can more easily control the flipping speed of the rotating bracket 2 to avoid excessive flipping of the rotating bracket 2.

[0028] In this embodiment, the second end of the friction rod 8 is rotatably connected to one end of a rocker 84 via a pin. The other end of the rocker 84 is rotatably connected to a connecting bracket 85, which is fixedly connected to the rotating bracket 2. A slide groove is provided on the rocker 84 to accommodate the sliding movement of the pin at the second end of the friction rod 8.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
