[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] The utility model provides a groove rolling machine support structure, the structure of which is as follows Figure 1 - Figure 2 As shown, it includes a supporting mechanism 1, a fixing mechanism 2 and a counterweight mechanism 3.

[0025] The support mechanism 1 includes a bracket 11 , a support ring 12 is provided on the top of the bracket 11 , and a positioning ring 13 is coaxially rotatably connected to the support ring 12 .

[0026] The fixing mechanism 2 is provided on the positioning ring 13 and is used to fix the steel pipe.

[0027] The counterweight mechanism 3 is provided on the bracket 11 , and is used to increase the weight of the bracket 11 .

[0028] During use, after the steel pipe is inserted into the positioning ring 13, the fixing mechanism 2 is activated. The fixing mechanism 2 ensures that the steel pipe does not move or shake during the grooving process, maintaining the steel pipe's position. The positioning ring 13 is coaxially connected to the support ring 12 for rotation, so that after the steel pipe is inserted into the positioning ring 13, the steel pipe can rotate freely within the positioning ring 13. During the grooving process, the rotation of the steel pipe can be achieved by the rotation of the positioning ring 13, reducing the frictional resistance between the steel pipe and the support structure.

[0029] In the present invention, the rotating connection of the positioning ring 13 and the stable fixation of the fixing mechanism 2 enable the steel pipe to maintain accurate position and rotational movement during the grooving process, thereby improving the processing quality. The addition of the counterweight mechanism 3 makes the bracket 11 more stable, reduces the shaking and vibration caused by external forces during the grooving process, and further improves the processing quality.

[0030] To improve the stability of the steel pipe rotation, please refer to Figure 1 In a preferred embodiment, the support ring 12 and the positioning ring 13 are connected through a bearing 4, and the bearing 4 includes an outer ring 41 and an inner ring 42 that are rotatably connected. The outer ring 41 is fixedly connected to the support ring 12, and the inner ring 42 is fixedly connected to the positioning ring 13.

[0031] During operation, when the groove rolling machine begins applying force to the steel pipe, causing it to rotate, the steel pipe drives the positioning ring 13 to rotate along with it. Since the inner ring 42 is fixed to the positioning ring 13, the rotation of the positioning ring 13 also drives the inner ring 42 to rotate. The outer ring 41, on the other hand, remains stationary on the support ring 12. The function of the bearing 4 is to enable the inner ring 42 to rotate smoothly within the outer ring 41 through its internal rolling elements. This allows the positioning ring 13 to rotate freely relative to the support ring 12, reducing frictional resistance during rotation and thus ensuring the quality and precision of the groove rolling.

[0032] To secure the steel pipe, refer to Figure 1 In a preferred embodiment, the fixing mechanism 2 includes a plurality of pressure rods 21 that are symmetrically and radially connected to the positioning ring 13 for sliding. The positioning ring 13 is provided with a driving assembly 5 for driving the pressure rods 21 to slide, so that the ends of the pressure rods 21 abut against the side wall of the steel pipe.

[0033] During use, the steel pipe is inserted into the positioning ring 13 so that it is roughly located at the center of the positioning ring 13. The driving assembly 5 on the positioning ring 13 is started, and the driving assembly 5 generates power to start pushing the pressure rods 21 to slide radially on the positioning ring 13. As the driving assembly 5 acts, multiple pressure rods 21 simultaneously approach the side wall of the steel pipe. Because the pressure rods 21 are symmetrically distributed along the radial direction of the positioning ring 13, they can apply pressure to the steel pipe from multiple directions at the same time. When the ends of the pressure rods 21 contact the side wall of the steel pipe, the continued sliding pressure rods 21 will gradually increase the pressure on the steel pipe, so that the ends of the pressure rods 21 are tightly against the side wall of the steel pipe. This symmetrical clamping method can ensure that the steel pipe is subjected to uniform force in all directions, so that it is firmly fixed in the positioning ring 13 and will not move or rotate.

[0034] To improve the stability of the steel pipe, please refer to Figure 1 In a preferred embodiment, an anti-slip layer 22 is provided at the end of the pressure rod 21.

[0035] During use, when the driving assembly 5 pushes the pressure rod 21 toward the side wall of the steel pipe, the anti-slip layer 22 at the end of the pressure rod 21 gradually contacts the side wall of the steel pipe. The anti-slip layer 22 is usually made of a material with a high friction coefficient, which can increase the friction between the end of the pressure rod 21 and the side wall of the steel pipe.

[0036] To drive the pressing rod 21 to slide, please refer to Figure 2 In a preferred embodiment, the driving assembly 5 includes a pressure ring 51 that is axially slidably connected to the positioning ring 13, and the pressure ring 51 is provided with a slope 52, and the slope 52 is used to abut against the end of the pressure rod 21, so that the pressure rod 21 slides radially along the positioning ring 13, and the positioning ring 13 is provided with a fixing assembly 6 for fixing the pressure ring 51.

[0037] During use, when it is necessary to fix the steel pipe, the pressure ring 51 is pushed along the axial direction of the positioning ring 13, and the pressure ring 51 begins to slide on the positioning ring 13. As the pressure ring 51 slides, the inclined surface 52 on the pressure ring 51 gradually approaches and contacts the end of the pressure rod 21. Due to the existence of the inclined surface 52, when the pressure ring 51 continues to slide, the inclined surface 52 will generate a component force along the radial direction of the positioning ring 13 on the end of the pressure rod 21. This component force causes the pressure rod 21 to slide radially on the positioning ring 13, gradually approaching the side wall of the steel pipe. As the pressure ring 51 continues to slide, the pressure rod 21 continues to move toward the side wall of the steel pipe under the action of the inclined surface 52 until the end of the pressure rod 21 is tightly against the side wall of the steel pipe. Multiple pressure rods 21 apply pressure to the steel pipe at the same time, firmly fixing the steel pipe in the positioning ring 13.

[0038] To fix the pressure ring 51, please refer to Figure 2 In a preferred embodiment, the fixing assembly 6 includes a bolt 61 threadedly connected to the positioning ring 13 , the bolt 61 moves radially along the positioning ring 13 , and the end of the bolt 61 is used to abut against the pressure ring 51 .

[0039] During use, the bolt 61 is manually rotated. Since the bolt 61 is threadedly connected to the positioning ring 13, the bolt 61 moves toward the pressure ring 51. As the bolt 61 continues to rotate and move, the end of the bolt 61 finally abuts against the pressure ring 51. The bolt 61 applies pressure to the pressure ring 51 to prevent the pressure ring 51 from moving in the axial direction of the positioning ring 13. Since the pressure ring 51 is fixed, the position of the inclined surface 52 on the pressure ring 51 remains unchanged, thereby ensuring that the pressure rod 21 continues to apply a clamping force to the steel pipe, so that the steel pipe remains in a stable fixed state during the grooving process.

[0040] To improve the convenience of operation, please refer to Figure 2 In a preferred embodiment, a handle 62 is provided on the bolt 61 .

[0041] During use, the design of the handle enables the operator to apply rotational force more easily, which is more labor-saving and convenient than directly rotating the bolt 61.

[0042] To increase the weight of the bracket 11, please refer to Figure 1 In a preferred embodiment, the counterweight mechanism 3 includes a support plate 31 provided on the bracket 11 , and a counterweight block 32 is provided on the support plate 31 .

[0043] During use, the weight of the steel pipe and the forces generated by the groover during operation can impact the support structure, potentially causing instability. The counterweight 32 on the support plate 31 increases the weight of the bracket 11, thereby improving the stability of the entire support structure. This provides reliable support for the groover's groove operation on the steel pipe, enhancing processing quality.

[0044] To improve the stability of the counterweight 32, please refer to Figure 1 In a preferred embodiment, a support rod 33 is provided on the support plate 31, and a through hole 34 for the support rod 33 to pass through is provided on the counterweight block 32. A nut 35 is threadedly connected to the support rod 33, and the nut 35 abuts against the top of the counterweight block 32.

[0045] During use, the through hole 34 on the counterweight 32 is aligned with the support rod 33, and the counterweight 32 is then lowered along the support rod 33 so that the support rod 33 passes through the through hole 34 of the counterweight 32. When the counterweight 32 is placed on the support plate 31, the support rod 33 extends from the top of the counterweight 32. The nut 35 on the support rod 33 is manually rotated. Since the nut 35 is threadedly connected to the support rod 33, the nut 35 moves downward along the support rod 33 during rotation. As the nut 35 continues to rotate and descend, the bottom of the nut 35 gradually approaches and eventually abuts against the top of the counterweight 32. The nut 35 is further rotated, and the nut 35 applies downward pressure to the counterweight 32, firmly fixing the counterweight 32 to the support plate 31. The connection between the support rod 33 and the nut 35 ensures that the counterweight 32 can be firmly fixed to the support plate 31 under any circumstances, providing a continuous and stable counterweight effect for the grooving operation.

[0046] In order to make the counterweight 32 slide onto the support rod 33 more easily, please refer to Figure 1 In a preferred embodiment, the top of the support rod 33 is spherical.

[0047] During use, since the top of the support rod 33 is spherical, the spherical portion can play a guiding role in the process of placing the counterweight 32, making it easier and more accurate to put the counterweight 32 on the support rod 33.

[0048] In order to better understand the present invention, the following Figure 1 - Figure 2The working principle of the technical solution of the groove rolling machine support structure of the utility model is described in detail: after the steel pipe is inserted into the positioning ring 13, the fixing mechanism 2 is activated. The fixing mechanism 2 is used to ensure that the steel pipe does not move or shake during the groove rolling process, and the position of the steel pipe is kept stable. The positioning ring 13 is coaxially connected to the support ring 12 for rotation, so that when the steel pipe is inserted into the positioning ring 13, the steel pipe can rotate freely within the positioning ring 13. During the groove rolling process, the rotation of the steel pipe is achieved by the rotation of the positioning ring 13, reducing the friction resistance between the steel pipe and the support structure.

[0049] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
