During the welding process, the workpiece and the solder melt to form a molten area. After the molten pool cools and solidifies, a connection is formed between the materials. When welding pipes, supports are usually required for support.

[0003] In the prior art, such as in publication number CN220407552U, a functional support for welding pressure pipelines is disclosed. It includes a support body, a placement block disposed on the support body for limiting the pipeline, a clamping device disposed on the support body for clamping the pipeline, and a drive motor disposed on both sides of the support body for driving the clamping device.

[0004] While the aforementioned patent facilitates the limiting and adjustment of pipe clamping by providing a clamping device and a placement block, preventing pipe from falling and facilitating disassembly and maintenance, it cannot monitor the clamping force, which can easily lead to insecure clamping and displacement of the welding position. In addition, the specifications of the clamping structure cannot be adjusted, making it unsuitable for welding pipes of different diameters. Therefore, a functional support for pressure pipe welding is proposed to address the above problems. Utility Model Content

[0014] The advantages of this utility model are:

[0015] 1.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1-4 As shown, a functional support for welding pressure pipelines includes a base 1. A support 2 is fixedly connected to the top surface of the base 1 in an axisymmetric manner. Electric push rods 3 are fixedly connected to the sides of the two supports 2 at equal intervals. An adjustment component 4 is fixedly connected to one end of the electric push rod 3. A contact component 5 is fixedly connected to the side of the adjustment component 4. A groove is formed on the surface of the base 1, and a control plate 6 is fixedly connected inside the groove. The adjustment component 4 includes a slide groove 41 fixedly connected to one end of the electric push rod 3. A slider 42 is slidably connected inside the slide groove 41 in an axisymmetric manner. Positive and negative lead screws 43 are slidably connected inside the two sliders 42.

[0025] During operation, the pressure sensor 52, model TE Connectivity FC23, is connected to the control board 6, model Arduino Mega 2560+, via a signal line. When the rubber block 53 at the end of the clamping rod 51 contacts the pipe, the pressure sensor 52 detects the clamping pressure in real time and feeds it back to the control board 6. If the pressure is lower than the preset threshold, the control board 6 drives the electric push rod 3, model ThomsonElectrak 10, to extend to increase the clamping force. If the pressure exceeds the threshold, the stroke of the electric push rod 3 is shortened. The clamping force is dynamically adjusted through closed-loop control. At the same time, the arc-shaped structure of the rubber block 53 fits against the outer wall of the pipe to avoid local stress concentration that could cause pipe deformation.

[0026] Furthermore, the contact assembly 5 includes clamping rods 51 that are fixedly connected to the sides of the two sliders 42 respectively. One end of the clamping rod 51 is fixedly connected to a pressure sensor 52, and a rubber block 53 is fixedly connected to the side of the pressure sensor 52.

[0027] During operation, the forward and reverse screws 43 are fixed to the bottom surface of the slide groove 41 via the bearing 8. When the screw block 7 is rotated, the forward and reverse screws 43 drive the sliders 42 on both sides to slide synchronously in opposite directions along the slide groove 41, thereby increasing or decreasing the distance between the two sets of clamping rods 51 to adapt to the positioning requirements of pipes with different diameters. At the same time, the electric push rod 3 pushes the adjustment component 4 to move as a whole, so that the rubber blocks 53 at the ends of the four sets of clamping rods 51 symmetrically press against the pipe from both sides. Combined with the sliders 42 with opposite screw directions, the clamping synchronization is achieved, ensuring that the pipe is stably fixed during the welding process.

[0028] Furthermore, a screw block 7 is fixedly connected to the top of the positive and negative screw 43, and a bearing 8 is sleeved on the bottom of the positive and negative screw 43. The bearing 8 is fixedly connected to the inner bottom surface of the slide groove 41.

[0029] During operation, the rotating screw block 7 drives the forward and reverse screws 43 to rotate, causing the sliders 42 on both sides to slide synchronously in opposite directions along the slide groove 41, thereby adjusting the spacing of the clamping rods 51 to achieve adaptive clamping for different pipe diameters. This structure reduces the difficulty of adjustment operation and extends the service life of the screws by manually and precisely adjusting the support stability of the bearings 8, thus avoiding jamming problems caused by friction.

[0030] Furthermore, the clamping rods 51 are configured as four groups symmetrically distributed, and the rubber block 53 at the end of each group of clamping rods 51 has an arc-shaped structure.

[0031] During operation, when the pipe is clamped, the arc-shaped rubber block 53 fits tightly against the outer wall of the pipe. The pressure sensor 52 detects the clamping pressure at each point in real time and feeds it back to the control board 6 to ensure that the four sets of clamping forces are evenly distributed. This design effectively disperses local stress and prevents pipe deformation or slippage through the combination of multi-directional symmetrical clamping and arc-shaped contact surface, while increasing the clamping contact area to enhance the fixation stability.

[0032] Furthermore, the electric push rod 3 is electrically connected to the control board 6, and the signal output terminal of the pressure sensor 52 is connected to the control board 6;

[0033] During operation, the pressure sensor 52 transmits the real-time detected clamping pressure signal to the control board 6. The pressure threshold comparison module built into the control board 6 automatically controls the extension and retraction of the electric push rod 3 according to the preset pressure range. When the pressure is lower than the threshold, the electric push rod 3 is driven to extend and pressurize. When the pressure exceeds the threshold, it retracts and depressurizes. This closed-loop control system realizes intelligent control of the clamping force by dynamically adjusting the stroke of the electric push rod 3. This avoids errors caused by human intervention and ensures that the clamping force is always within a safe range, significantly improving the automation level and safety of welding operations.

[0034] Working principle: During operation, the pipe to be welded is placed between the two sets of supports 2 above the base 1. After starting, the electric push rod 3 drives the adjusting component 4 to move towards the pipe through the command of the control board 6. The sliding groove 41 of the adjusting component 4 is connected to two sliders 42 with opposite screw directions through the positive and negative screws 43. When the screw block 7 at the top of the positive and negative screws 43 is rotated, the bearing 8 at the bottom of the screw supports its rotation, so that the sliders 42 on both sides slide synchronously in opposite directions along the sliding groove 41, driving the clamping rod 51 to adjust the spacing to adapt to pipes of different diameters; when the arc-shaped rubber block 53 at the end of the clamping rod 51... When in contact with the pipe surface, the pressure sensor 52 detects the clamping pressure in real time and transmits the signal to the control board 6. If the pressure is lower than the preset threshold, the control board 6 controls the electric push rod 3 to continue to advance to increase the clamping force. If the pressure exceeds the threshold, the electric push rod 3 will automatically retract, forming a closed-loop feedback adjustment. The four sets of axisymmetrically distributed clamping rods 51 achieve symmetrical clamping through the synchronous movement of the slider 42. Combined with the arc-shaped contact surface of the rubber block 53, the pressure is evenly distributed. Finally, under the synergistic effect of dynamic adjustment and multi-directional clamping, the stable fixation of the pipe and real-time force control protection during the welding process are completed.

[0035] The above description is merely 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. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
