[0021] The following combines specific embodiments to further elaborate on the content of the present utility model:

[0022] As Figure 1 - Figure 3 shown, an iron ring flipping device includes a base 1 arranged horizontally at the bottom. A body 2 is bolted to the base 1 vertically. In other implementation modes of this application, the body 2 and the base 1 can also be integrally formed. One end of the body 2 away from the base 1 is connected with a flipping part 3. The flipping part 3 can rotate around a horizontal axis, and a clamping part 4 is arranged at the end away from the body 2. The clamping part 4 includes a pair of clamping arms 41. The end of the clamping arm 41 away from the flipping part 3 is used as the clamping end and clamps an iron ring 7. Through the rotation of the flipping part 3, the iron ring 7 clamped on the clamping arm 41 can be turned over by 180°.

[0023] In order to enable this device to clamp iron rings 7 of different specifications and different diameters, the clamping part 4 is connected to the flipping part 3 through an adjusting mechanism 5. As Figure 3 shown, the flipping part 3 includes a flipping housing 31. The interior of the flipping housing 31 is hollow, and the adjusting mechanism 5 is accommodated inside the flipping housing 31. The adjusting mechanism 5 includes a swing cylinder 51 arranged horizontally. The swing cylinder 51 is installed in the flipping housing 31 through a fixing frame. The swing cylinder 51 has two execution ends that can move synchronously left and right. One end of the clamping arm 41 is fixed to the execution end of the swing cylinder 51. When the two execution ends of the swing cylinder 51 extend or contract, the distance between a pair of clamping ends of the clamping arm 41 can be changed.

[0024] The flipping part 3 includes a rotating shaft 32. The rotating shaft 32 is arranged on the upper part of the body 2 and penetrates the body 2 to be fixed to the flipping housing 31. Driven by a flipping motor 33, the rotating shaft 32 drives the flipping housing 31 to rotate around the axis of the rotating shaft 32, and the axis of the rotating shaft 32 coincides with the midpoint of the line connecting a pair of clamping ends, so that the iron ring 7 before and after flipping remains at the same height.

[0025] Notches 6 are provided at both ends of the flipping housing 31 corresponding to the clamping arms 41. As Figure 4As shown, the notch 6 is set as an L-shaped structure, which can be divided into a first part 61 and a second part 62 communicating with the first part 61. Among them, the first part 61 allows the clamping arm 41 to pass through and provides a space for changing the distance when the clamping arm 41 moves with the swing cylinder 51. The second part 62 is arranged corresponding to the mounting block 52 and is used to provide an operating space for the installation of the clamping arm 41 and the execution end of the swing cylinder 51.

[0026] As Figure 1 shown, a jaw cylinder 42 is installed at the clamping end of the clamping arm 41. The jaw cylinder 42 has a clamping surface arranged in the horizontal direction and performs a clamping action in the vertical direction, so as to clamp the iron ring 7 in a horizontal state. Further, in order to prevent the iron ring 7 from being deformed by the clamping of the jaw cylinder 42 or scratches appearing on the surface of the iron ring 7, a protective pad 43 made of rubber material is provided at the clamping end of the jaw cylinder 42. After the jaw cylinder 42 clamps the iron ring 7, a pair of protective pads 43 abut against both end faces of the iron ring 7.

[0027] In addition, as Figure 2 shown, magnetic switches 53 are also arranged in pairs on the swing cylinder 51. The magnetic switches 53 are arranged corresponding to the two execution ends of the swing cylinder 51. When the swing cylinder 51 drives the clamping arm 41 to adjust for iron rings 7 of different specifications, when the two execution ends of the swing cylinder 51 run to the preset positions, they will respectively trigger a pair of magnetic switches 53 and then stop moving, that is, the two execution ends of the swing cylinder 51 move in place.

[0028] During operation:

[0029] According to the diameter of the iron ring 7 to be clamped, control the two execution ends of the swing cylinder 51 to open the corresponding distance. Place both ends of the iron ring 7 in the jaw cylinder 42 at the end of the clamping arm 41 and clamp it. Start the flipping motor 33, drive the rotating shaft 32 to drive the flipping part 3 to drive the clamping part 4 and the iron ring 7 to rotate around the axis of the rotating shaft 32.
