[0002] Pipe bends, as the name suggests, refer to pipes whose axes are not aligned with a straight line after processing. It is a form of pipe processing, typically manufactured through heating, bending, and other techniques, and is widely used in various industrial piping systems, structural frames, and decorative designs.

[0003] During the pipe bending process, deviations in angle can affect the product's performance and safety. Therefore, before being put into use, pipe bends need to be inspected by a testing agency to determine whether they meet the standards.

[0004] Among them, the testing agencies are mostly equipped with positioning mechanisms for fixing the bends to maintain stability during the testing of the bends. However, the positioning mechanisms in traditional technologies mostly lock the bends by directly clamping them. Since the clamped items are pipes, the bends are easily deformed by pressure, making them difficult to put into subsequent use.

[0044] In summary, the laser contour sensor 3 is a mature existing technology, and will not be elaborated further here;

[0045] In this embodiment, a linear groove is provided on the side of the support platform 6 near the linear guide rail 5, and the support platform 6 is connected to the outside of the linear guide rail 5 through the linear groove.

[0046] More specifically, the linear slide rails enable the bearing platform 6 to be stably assembled with the linear guide rail 5, ensuring that the bearing platform 6 can be adjusted within the limits of the linear guide rail 5.

[0047] Furthermore, both the linear guide 5 and the linear groove can be H-shaped;

[0048] In this embodiment, a stabilizing frame is fixedly connected to the bottom end of the support platform 6 away from the support frame 4, and a stabilizing wheel is rotatably connected to the bottom end of the stabilizing frame;

[0049] More specifically, by setting up the stabilizing wheel, the end of the bearing platform 6 that is away from the bearing frame 4 can be provided with auxiliary support, and when the bearing platform 6 moves along the linear guide rail 5, it drives the stabilizing wheel to move at the support base 1, thereby ensuring the stability of the bearing platform 6 during adjustment.

[0050] In this embodiment, in order to ensure the smooth rotation of the stabilization wheel on the stabilization frame, a ball bearing is also provided at the connection between the stabilization wheel and the stabilization frame.

[0051] In this embodiment, the positioning component 7 includes:

[0052] Positioning seat 9 is fixedly connected to the middle of the bottom end of the support platform 6. A guide cylinder 10 is fixedly connected to the inner side of the positioning seat 9. An electric push rod 11 is fixedly connected to one end of the positioning seat 9. A displacement plate 12 is fixedly connected to the output end of the electric push rod 11, and the output end of the electric push rod 11 is located inside the guide cylinder 10.

[0053] Two assembly racks 13 are fixedly connected to the top of each assembly rack 13. One end and the bottom of each assembly rack 13 are fixedly connected to a positioning suction cup 15. A flexible hose 16 is fixedly connected to one side of the assembly rack 13, and the end of the flexible hose 16 away from the assembly rack 14 is connected to the inner cavity of the guide tube 10.

[0054] In this embodiment, a sealing ring is fixedly connected to the outer side of the displacement plate 12, and the sealing ring and the inner wall of the guide cylinder 10 are in transition fit.

[0055] More specifically, by setting the sealing ring, a dynamic seal can be formed after the displacement plate 12 is adjusted without affecting the movement of the displacement plate 12 inside the guide cylinder 10, thus preventing uncontrollable movement of gas inside the guide cylinder 10.

[0056] Furthermore, to ensure the sealing effect of the sealing ring, the sealing ring can be made of rubber;

[0057] Example 2:

[0058] Please see Figure 1-5 This embodiment provides a technical solution based on Embodiment 1: the push component 8 includes:

[0059] Assembly base 17 is fixedly connected to one end of support base 1 near bracket 2. A drive motor 18 is fixedly connected to the bottom end of assembly base 17. A drive spur gear 19 is fixedly connected to the output end of drive motor 18.

[0060] The transmission rack 20 is fixedly connected to the bottom of the support platform 6 near the transmission spur gear 19, and the transmission rack 20 is also meshed with the transmission spur gear 19.

[0061] In this embodiment, a clearance groove is provided at one end of the support base 1 near the bracket 2, and the mounting base 17 is connected to the inside of the clearance groove by bolts;

[0062] More specifically, by setting up the clearance groove, sufficient assembly space can be provided for the drive motor 18 between the support base 1 and the bearing platform 6, thereby ensuring the application effect of the drive motor 18.

[0063] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0064] Working principle: First, place the bent tube on the top of the support platform 6. Then, place the two assembly brackets 13 at the two ends of the bent tube respectively, and make the positioning suction cup 15 at one end of the transmission pipe 14 fit against the bent tube. At the same time, start the electric push rod 11 to drive the displacement plate 12 to move inside the guide cylinder 10, and transmit the gas inside the transmission pipe 14 into the guide cylinder 10 through the hose 16, causing a negative pressure to be generated inside the transmission pipe 14. Finally, the positioning suction cup 15 at the bottom of the transmission pipe 14 will be adsorbed onto the support platform 6, and the positioning suction cup 15 at one end of the transmission pipe 14 will be adsorbed onto the end of the bent tube, thus forming the adsorption positioning of the bent tube.

[0065] The drive motor 18 is started, which causes the drive spur gear 19 to move the drive rack 20. In conjunction with the connection between the drive rack 20 and the support platform 6, the support platform 6 moves towards the laser profile sensor 3 under the limit of the linear guide rail 5. This causes the bent pipe to pass through the laser profile sensor 3, so that a three-dimensional model of the bent pipe can be constructed through the laser profile sensor 3. In the reconstructed three-dimensional model, the bent part of the bent pipe can be identified, and the angle of the bent pipe can be determined by calculating the included angle between adjacent straight line segments.
