[0001] This application relates to the technical field of steel pipe cutting, and in particular to a fixing device for steel pipe cutting. Background Technique

[0002] A steel pipe is a steel material with a hollow cross-section, and its length is much greater than the diameter or circumference. Currently, when using a steel pipe, a cutting device is usually used to cut the steel pipe to a certain length. However, since the steel pipe is a circular material, a fixing device is usually required to clamp and fix the steel pipe during cutting. However, it is found in actual processing that the sizes of steel pipes are different, and the existing cutting and fixing devices are difficult to meet the fixing requirements of steel pipes of different sizes, so they have certain limitations. Therefore, a fixing device for steel pipe cutting is proposed to solve the problems described in the above background technique.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following will further describe the present application in detail with reference to Figure 1 —3.

[0018] The embodiment of the present application discloses a steel pipe cutting and fixing device.

Fixed seats 2 are symmetrically and fixedly connected to the conveying frame 1. Threaded rods 3 are rotatably connected to both sides of the fixed seats 2. By rotating the threaded rods 3, it is convenient to adjust the position of the limiting plates 4. The ends of the two threaded rods 3 are rotatably connected to the limiting plates 4. The two limiting plates 4 are both arranged at the middle position of the conveying frame 1. The steel pipe on the conveying frame 1 is limited by the two limiting plates 4. A clamping assembly 5 is arranged on one side of the conveying frame 1. The clamping assembly 5 facilitates the fixing of steel pipes of different sizes, which is convenient for subsequent cutting of the steel pipe;

[0019] During cutting, place the steel pipe on the conveying rack 1. Adjust the distance between the two limiting plates 4 by rotating the threaded rods 3 on both sides, so that the two limiting plates 4 limit the steel pipe on the conveying rack 1. Subsequently, it is convenient for the steel pipe to move through the conveying rack 1. Then, fix the steel pipe through the clamping assembly 5 to facilitate subsequent cutting of the steel pipe.

[0020] Refer to Figures 2-3 , the clamping assembly 5 includes a cross plate 6. The cross plate 6 is fixedly connected to one end of the conveying rack 1. A hydraulic rod 7 is fixedly connected to the conveying rack 1. The hydraulic rod 7 facilitates providing power for the device subsequently. Clamping seats 8 are symmetrically arranged on the top of the cross plate 6. The clamping seats 8 facilitate clamping and fixing the steel pipe. Connecting plates 9 are fixed to the rear sides of the two clamping seats 8 respectively. The connecting plates 9 facilitate the connection of components. The two connecting plates 9 are movably arranged on the top of the cross plate 6. A gear 10 is arranged on the conveying rack 1. The gear 10 is rotatably connected to the conveying rack 1 through a rotating shaft 11. Sliding grooves 12 are symmetrically formed on both sides of the gear 10. A first rack 13 is movably connected inside one sliding groove 12, and a second rack 14 is movably connected inside the other sliding groove 12, so that the first rack 13 and the second rack 14 can move inside the two sliding grooves 12 respectively. The gear 10, the first rack 13 and the second rack 14 are all arranged at the bottom of the cross plate 6. The gear 10 is arranged between the first rack 13 and the second rack 14, and both the first rack 13 and the second rack 14 are meshed with the gear 10. When the first rack 13 moves, it drives the gear 10 to drive the second rack 14 to move. The two connecting plates 9 are respectively fixed to the first rack 13 and the second rack 14. The end of the hydraulic rod 7 is fixedly connected to the first rack 13, so that the hydraulic rod 7 can push the first rack 13 to move; at the idle place of this device, connect all the above-mentioned electrical components, which refer to power components, electrical components and the adapted controller and power supply through wires. For the specific connection means, refer to the following working principle for the sequential working order between each electrical component to complete the electrical connection. The detailed connection means are well-known techniques in this field;

[0021] When clamping and fixing, first move the steel pipe between the two clamping seats 8, and then start the hydraulic rod 7. The hydraulic rod 7 pushes the first rack 13 to move. When the first rack 13 moves, it drives the gear 10 to drive the second rack 14 to move, so that the first rack 13 and the second rack 14 drive the clamping seats 8 to move, thereby clamping and fixing the steel pipe through the two clamping seats 8.

[0022] The implementation principle of a steel pipe cutting and fixing device according to an embodiment of the present application is as follows: During cutting, the steel pipe is placed on the conveying rack 1, and the distance between the two limiting plates 4 is adjusted by rotating the threaded rods 3 on both sides, so that the two limiting plates 4 limit the steel pipe on the conveying rack 1. Subsequently, during clamping and fixing, first move the steel pipe between the two clamping seats 8, and then start the hydraulic rod 7. The hydraulic rod 7 pushes the first rack 13 to move. When the first rack 13 moves, it drives the gear 10 to drive the second rack 14 to move, so that the first rack 13 and the second rack 14 drive the clamping seats 8 to move, thereby clamping and fixing the steel pipe by the two clamping seats 8.
