Abstract
Description
Technical Field
[0001] This utility model relates to an auxiliary leveling device, specifically a device that can adjust the levelness of pipes to ensure that they can be cut smoothly in a cutting machine, belonging to the technical field of pipe auxiliary leveling equipment. Background Technology
[0002] During the pipe cutting process, whether it's square or round pipe, due to limitations in the working environment and conditions, it's often difficult to find a pad with the required size, shape, and hardness to effectively level and support the pipe. This is especially true for round pipes with curved surfaces; if placed directly on a regular platform or simple support, there is often only localized point or line contact, making it difficult to maintain overall stability during cutting. This results in the pipe being suspended, tilted, or swaying during cutting. Due to the lack of a stable reference surface, the cutting tool or saw blade is prone to uneven resistance, causing the cutting path to deviate from the preset direction. Ultimately, this results in skewed cut surfaces, cuts that are not perpendicular to the pipe axis, and even quality problems such as tearing and increased burrs. Uneven and skewed cut surfaces not only affect the appearance quality of the pipe, but also cause deviations in key dimensions such as the length and end face angle of the cut pipe. These dimensional errors will further accumulate and amplify in subsequent assembly, welding, and other processing operations, which may cause problems such as misalignment of components, uneven gaps, and stress concentration, seriously affecting the accuracy and overall strength of structural components, and even causing workpiece scrapping, project delays, and material waste. Therefore, an auxiliary device is needed to stabilize the pipe and ensure its level during the cutting process. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pipe auxiliary leveling device suitable for cutting machines. It can effectively stabilize the pipe and correct the levelness of the pipe, ensuring the smooth progress of the cutting operation.
[0004] The problem described in this utility model is solved by the following technical solution: A pipe-assisted leveling device suitable for a cutting machine includes two leveling parts, with the pipe placed on the two leveling parts and the end of the pipe located on the cutting machine. Each leveling part includes a base plate, a lifting mechanism, a supporting mechanism, and a limiting mechanism. There are two lifting mechanisms, which are symmetrically arranged on both sides of the top surface of the base plate. The supporting mechanism is located between the tops of the two lifting mechanisms. The limiting mechanism is located on the supporting mechanism.
[0005] The above-mentioned pipe auxiliary leveling device for cutting machines includes a lifting mechanism comprising a vertical guide column, a guide rod, and a horizontal plate. The vertical guide column is located on one side of the top surface of the base plate. The guide rod is inserted into a hole at the top of the vertical guide column. A threaded hole is provided on the side wall of the vertical guide column, and a bolt passes through the threaded hole on the side wall of the vertical guide column and presses against the side wall of the guide rod.

[0006] The above-mentioned pipe auxiliary leveling device applicable to cutting machines includes a lifting mechanism comprising a roller and a horizontal bar; both the roller and the horizontal bar are disposed between two horizontal plates; the side wall of the horizontal plate is provided with a hole, and the inner wall of the hole is connected to the outer wall of the outer ring of the bearing; the connecting rod at the end of the roller is connected to the inner wall of the inner ring of the bearing; the height of the top surface of the horizontal bar is lower than the height of the roller axis.
[0007] The aforementioned tube-assisted leveling device for a cutting machine includes a limiting mechanism comprising two limiting components, both of which are mounted on a horizontal rod. Each limiting component comprises a slider, a vertical limiting plate, and a horizontal limiting plate. The slider has a central hole through which the horizontal rod passes.

One end of the horizontal limiting plate has a hole through which the vertical limiting plate passes. A threaded hole is located on the side wall of the horizontal limiting plate, through which a bolt passes and presses against the side wall of the vertical limiting plate.
[0008] This utility model adjusts the vertical height of the pipe through a lifting mechanism, and adjusts the levelness of the pipe through the cooperation of two leveling parts; the lifting mechanism ensures that the pipe can be reliably supported and can move forward smoothly, thus facilitating the workers to cut the pipe into multiple sections; the limiting mechanism ensures that the pipe can reliably move straight along the center line of the pipe during cutting or moving forward.

[0010] The list of labels in the diagram is as follows: 1. Base plate, 2. Vertical guide column, 3. Guide rod, 4. Horizontal plate, 5. Idler roller, 6. Horizontal rod, 7. Slider, 8. Vertical limit plate, 9. Horizontal limit plate. Detailed Implementation
[0011] refer to Figure 1This utility model includes two leveling parts, and the pipe is placed on the two leveling parts, with the end of the pipe located on the cutting machine; the two leveling parts cooperate to support the pipe and adjust its orientation and levelness to ensure that its center line is parallel to the horizontal line; and to ensure that the bottom end of the pipe is aligned with the platform of the cutting machine.
[0012] The leveling section includes a base plate 1, a lifting mechanism, a supporting mechanism, and a limiting mechanism. There are two lifting mechanisms, which are symmetrically arranged on both sides of the top surface of the base plate 1. The supporting mechanism is located between the tops of the two lifting mechanisms. The cooperation between the lifting mechanism and the supporting mechanism can adjust the height of the pipe so that it can be horizontally and reliably pressed against the cutting machine platform. The limiting mechanism is located on the supporting mechanism, and its function is to ensure that the pipe does not sway to the sides during the cutting process.
[0013] The lifting mechanism includes a vertical guide column 2, a guide rod 3, and a horizontal plate 4. The vertical guide column 2 is located on one side of the top surface of the base plate 1. The guide rod 3 is inserted into a hole at the top of the vertical guide column 2. A threaded hole is provided on the side wall of the vertical guide column 2, and a bolt passes through the threaded hole on the side wall of the vertical guide column 2 and presses against the side wall of the guide rod 3. The horizontal plate 4 is located at the top end of the guide rod 3 near the other lifting mechanism. By adjusting the vertical height of the guide rod 3, the height of the idler roller 5 is adjusted, thereby adjusting the height of the pipe on the idler roller 5. Then, by adjusting the height of the two idler rollers 5, the levelness of the pipe is adjusted. After the position of the idler roller 5 is determined, tightening the bolt on the side wall of the guide column 2 can fix the height of the idler roller 5.
[0014] The lifting mechanism includes a roller 5 and a horizontal bar 6; both the roller 5 and the horizontal bar 6 are disposed between two horizontal plates 4; the pipe presses against the roller 5; the side wall of the horizontal plate 4 is provided with a hole, and the inner wall of the hole is connected to the outer wall of the outer ring of the bearing, and the connecting rod at the end of the roller 5 is connected to the inner wall of the inner ring of the bearing; the roller can rotate, which makes it easy for the pipe to move forward; the top surface of the horizontal bar 6 is lower than the height of the axis of the roller 5, which avoids the pipe scraping against the horizontal bar 6.
[0015] The limiting mechanism includes two limiting components, both of which are mounted on the horizontal rod 6. Each limiting component includes a slider 7, a vertical limiting plate 8, and a horizontal limiting plate 9. The slider 7 has a central hole through which the horizontal rod 6 passes. The slider 7 has threaded holes on its sidewalls, and bolts pass through these holes and press against the horizontal rod 6. The distance between the two vertical limiting plates 8 can be adjusted by sliding the sliders on both sides. The pipe passes between the two vertical limiting plates 8. When the pipe is cutting... During cutting, the clamping and limiting action of the vertical limiting plates 8 on both sides prevents the pipe from swaying to either side; the vertical limiting plates 8 are set on the top surface of the slider 7; one end of the horizontal limiting plate 9 is provided with a hole, and the vertical limiting plate 8 passes through the hole at the end of the horizontal limiting plate 9; the side wall of the horizontal limiting plate 9 is provided with a threaded hole, and the bolt passes through the threaded hole on the side wall of the horizontal limiting plate 9 and presses against the side wall of the vertical limiting plate 8; the horizontal limiting plate presses against the top of the pipe, which ensures that the pipe will not sway in the vertical direction during cutting.
[0016] Operating principle: Place the two leveling components in front of the cutting machine, then place the pipe on the two rollers 5. Adjust the height of each guide rod 3 to adjust the height and level of the pipe, making it compatible with the cutting machine. After adjustment, tighten the bolts on the vertical guide column 2 to fix the position of the guide rod 3. Then, fine-tune the position of the pipe so that the preset cutting line is below the cutting saw of the cutting machine. Then, slide the slider 7 so that the two vertical limiting plates 8 press against the sides of the pipe. Then, move the horizontal limiting plate down so that it presses against the top of the pipe. Then, tighten the bolts on the slider 7 and the horizontal limiting plate to fix their positions, ensuring that they can reliably limit the pipe. Then, the cutting machine will start cutting. If it is necessary to cut in multiple segments, after cutting the next segment, continue to push the pipe forward along the center line until the next preset cutting line is below the cutting saw. Continue cutting until the cutting is completed, then remove the pipe. The cutting operation is now complete.
