[0019] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0020] A steel pipe clamping device for a seamless steel pipe flaring machine, such as Figures 1-5 As shown, the device includes a base 1, a mounting bracket 6, and a threaded rod 7. The base 1 has a support seat 5 on its top, with a semi-circular through hole. Two support seats 5 are arranged in a straight line on the top of the base 1. Each support seat 5 has a mounting bracket 6 on its top, and a threaded rod 7 is threadedly connected to the mounting bracket 6. A connecting plate 8 is located at the bottom of the threaded rod 7. A first arc-shaped plate 9 is located in the middle of the bottom of the connecting plate 8. The first arc-shaped plate 9 is the same size and shape as the semi-circular through hole. Cylinders 10 are located on both sides of the bottom of the connecting plate 8. A second arc-shaped plate 11 is located on the telescopic rod of each of the two cylinders 10, penetrating the first arc-shaped plate 9. Rectangular holes are located on both sides of the support seat 5, and an adjusting plate 13 is slidably connected within these rectangular holes. Several positioning holes are located on the adjusting plate 13. Fixed seats 12 are located on both sides of the support seat 5, and positioning rods 14 are located on the fixed seats 12. The positioning rods 14 fit into the positioning holes. The two support seats 5 can evenly distribute the pressure applied to the steel pipe, reducing the risk of steel pipe deformation.

[0021] like Figure 1 As shown, the device also includes a movable seat 2, a bidirectional screw 3, a first guide rod 4, a fixing block 16, and a knob 17. Fixing blocks 16 are provided on both the front and rear sides of the base 1. The bidirectional screw 3 and the first guide rod 4 are connected between the two fixing blocks 16. The movable seat 2 is threaded to the outer side of both the right-hand and left-hand threads of the bidirectional screw 3. The movable seat 2 is connected to the bottom of the support base 5. The first guide rod 4 passes through the movable seat 2. A knob 17 is provided at the front end of the bidirectional screw 3. When steel pipes of different lengths need to be processed, the knob 17 can be rotated, and the bidirectional screw 3 will drive the two movable seats 2 to move towards or relative to each other, adjusting the distance between the two movable seats 2 to adapt to the length of the steel pipe, further improving the flexibility of the device.

[0022] like Figure 3 As shown, it also includes a second guide rod 61. Several second guide rods 61 are provided between the upper and lower sides inside the mounting bracket 6. The second guide rods 61 pass through the connecting plate 8. The second guide rods 61 can ensure that the connecting plate 8 maintains linear movement during the movement and prevent the connecting plate from shifting or tilting when the 8 is raised or lowered.

[0023] like Figure 4 As shown, it also includes a first rubber pad 91 and a second rubber pad 111. The bottom of the first arc plate 9 and the second arc plate 11 are respectively provided with the first rubber pad 91 and the second rubber pad 111. The first rubber pad 91 and the second rubber pad 111 can provide additional cushioning and friction, which can protect the surface of the steel pipe from damage while improving the stability of the clamping during clamping.

[0024] like Figure 6As shown, it also includes an elastic protrusion 15. The positioning rod 14 is provided with an elastic protrusion 15 on its outer side. The rear side of the fixing seat 12 has a groove that fits the elastic protrusion 15. During the process of inserting the positioning rod 14 into the rear side of the fixing seat 12, the elastic protrusion 15 will be squeezed against the inner wall of the fixing seat 12 and deformed. When the elastic protrusion 15 reaches the groove position, it will restore its shape and be embedded in the groove to fix the positioning rod 14, preventing the positioning rod 14 from being sent or slipping out during the clamping process, thus improving the stability and safety of the device.

[0025] When processing steel pipes the same size as the semi-circular through hole, place the steel pipe on the support base 5, then rotate the threaded rod 7. The threaded rod 7 drives the connecting plate 8 and the first arc plate 9 to move downwards until the first arc plate 9 contacts the steel pipe. Then continue to tighten the threaded rod 7 so that the first arc plate 9 applies sufficient pressure to the steel pipe, thereby fixing the steel pipe. When processing steel pipes smaller than the semi-circular through hole, the two adjusting plates 13 can be moved to adjust the distance between the two adjusting plates 13. After finding a suitable distance, the positioning rod 14 is inserted into the positioning hole through the fixing base 12 to fix the position of the adjusting plate 13. Then rotate the threaded rod 7 to adjust the height of the connecting plate 8 to a suitable position, then start the cylinder 10. The cylinder 10 drives the second arc plate 11 to move through the telescopic rod until the second arc plate 11 is tightly attached to the surface of the steel pipe. Finally, close the cylinder 10.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
