Description

Technical Field

[0001] This utility model relates to the technical field of welding clamping devices, and in particular to an automatic centering welding clamping device for metal pipes. Background Technology

[0002] Pipe welding clamping devices are equipment used to fix and hold pipes during welding or other processing. These devices help ensure that the pipes maintain the correct position and stability during welding, thereby improving work efficiency and welding quality.

[0003] However, existing pipe welding clamping devices mostly use manual centering clamping in actual use. Manual centering clamping of pipe fittings is inaccurate in centering, and the pipe fittings are prone to misalignment during rotation, which can lead to poor welding. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides an automatic centering welding clamping device for metal pipes. Through the combination of a triangular support frame, a circular ring, a linear guide rail, Y-shaped clamps, and fixed wheels, the main body of the metal pipe is clamped by three fixed wheels mounted on one end of three Y-shaped clamps. By installing two Y-shaped clamps on one side of the support rod, the clamping of the metal pipe body by the two sets of Y-shaped clamps becomes more stable and less prone to displacement. This also prevents the pipe from becoming misaligned during the rotational welding process, thus avoiding welding defects. This automatic centering effectively avoids the inaccurate centering caused by manual centering clamping of the pipe.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an automatic centering welding clamping device for metal pipes, comprising an operating table and a metal pipe body, a mounting frame at the top of the operating table, a gear ring and a gear disk mounted inside the mounting frame, support columns evenly mounted between the gear ring and the gear disk, a triangular support frame fixedly mounted inside the gear ring, a circular ring fixedly mounted at the center of the triangular support frame, a metal pipe body mounted inside the circular ring, linear guide rails mounted at corresponding positions on the inner surface of the triangular support frame and the inner wall of the gear disk, Y-shaped clamping blocks mounted on the surface of the linear guide rails, and fixed wheels mounted at the bottom ends of the Y-shaped clamping blocks. The fixed wheel is located on the outer wall of the metal pipe body. A support rod is bolted to one side of the two Y-shaped clamps between the triangular support frame and the gear disk. A limit rod is fixedly installed at the center of one end of the support rod. A strip-shaped through hole is opened on the surface of the gear disk. A transmission disk is installed on the inner side of the gear disk. An arc-shaped limit hole is opened on the surface of the transmission disk. One end of the limit rod passes through the strip-shaped through hole and extends to the inner side of the arc-shaped limit hole. A transmission belt mounting plate is fixedly installed on one side of the transmission disk. A second motor is installed on the surface of the gear disk. A drive disk is fixedly installed at one end of the drive shaft of the second motor. The same transmission belt body is sleeved on the surface of the transmission belt mounting plate and the drive disk.

[0006] As a preferred technical solution of this utility model, the gear ring and gear disk have annular grooves on their surfaces, and the inner wall of the annular grooves is provided with locking teeth. A first motor is symmetrically installed on the top surface of the operating table. A transmission rod is fixedly installed at one end of the drive shaft of the first motor. Two drive gears are installed on the surface of the transmission rod. The two drive gears respectively engage with the locking teeth at the bottom of the gear ring and gear disk. A support bearing seat is sleeved on the surface of the transmission rod.

[0007] As a preferred technical solution of this utility model, two fixed rotating rods are symmetrically installed on the inner wall of the top of the mounting frame, and two limiting rollers are installed on the surface of the two fixed rotating rods. The bottom ends of the two limiting rollers are respectively located inside the annular grooves opened on the surface of the gear ring and the gear disk.

[0008] As a preferred technical solution of this utility model, a crossbar is fixedly arranged between the two Y-shaped clamping blocks, a U-shaped block is fixedly arranged at the center of the crossbar, a pressure sensing probe is installed at the center of the U-shaped block, and one end of the pressure sensing probe is electrically connected to a pressure sensor.

[0009] As a preferred embodiment of this utility model, the number of the first motors is set to two, with the two first motors located on both sides of the gear ring, and the two first motors are synchronous motors.

[0010] As a preferred embodiment of this utility model, the limiting rollers are provided in two sets, with the two sets of limiting rollers located on the top sides of the gear ring and the gear disk, respectively.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0012] 1. By combining a triangular support frame, a circular ring, a linear guide rail, a Y-shaped clamp, and fixed wheels, the main body of the metal pipe is held by the three fixed wheels installed at one end of the three Y-shaped clamps. By installing two Y-shaped clamps on one side of the support rod, the two sets of Y-shaped clamps hold the main body of the metal pipe more stably and are less prone to displacement. This also avoids the situation where the pipe is misaligned during the rotation and welding of the main body of the metal pipe, which may cause poor welding. This automatic centering setting effectively avoids the situation where the centering is inaccurate when manually centering and clamping the pipe.

[0013] 2. The combination of the drive gear, the first motor, the gear ring, and the gear disc facilitates the rotational welding of the metal pipe body; the setting of the fixed rotating rod and the limiting roller facilitates the limited rotation of the gear ring and the gear disc.

[0019] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation are all within the protection scope of this utility model without creative effort.

[0020] For an example, please refer to... Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, this utility model provides an automatic centering welding clamping device for metal pipes, including an operating table 1 and a metal pipe body 15. A mounting frame 2 is provided at the top of the operating table 1. A gear ring 3 and a gear disk 16 are mounted inside the mounting frame 2. Support columns 5 are evenly installed between the gear ring 3 and the gear disk 16. A triangular support frame 4 is fixedly installed inside the gear ring 3. A circular ring 8 is fixedly installed at the center of the triangular support frame 4. The metal pipe body 15 is mounted inside the circular ring 8. Linear guide rails 11 are installed at corresponding positions on the inner surface of the triangular support frame 4 and the inner wall of the gear disk 16. Y-shaped clamping blocks 12 are mounted on the surface of the linear guide rails 11. 2. A fixed wheel 13 is installed at the bottom end, which is located on the outer wall of the metal pipe body 15. A support rod 9 is bolted to one side of the two Y-shaped clamps 12 between the triangular support frame 4 and the gear disk 16. A limit rod 10 is fixedly installed at the center of one end of the support rod 9. A strip-shaped through hole 23 is opened on the surface of the gear disk 16. A transmission disk 19 is installed inside the gear disk 16. An arc-shaped limit hole 21 is opened on the surface of the transmission disk 19. One end of the limit rod 10 passes through the strip-shaped through hole 23 and extends to the inside of the arc-shaped limit hole 21. A transmission belt mounting plate 20 is fixedly installed on one side of the transmission disk 19. A second motor is installed on the surface of the gear disk 16. 17. One end of the drive shaft of the second motor 17 is fixedly equipped with a drive disc 18, and the same drive belt body 22 is sleeved on the surface of the drive disc 18 and the drive belt mounting disc 20. Through the combination of the triangular support frame 4, the ring 8, the linear guide rail 11, the Y-shaped clamp 12, and the fixed wheel 13, the metal pipe body 15 is triangularly supported and clamped by the three fixed wheels 13 installed at one end of the three Y-shaped clamps 12. By installing two Y-shaped clamps 12 on one side of the support rod 9, the clamping of the metal pipe body 15 by the two sets of Y-shaped clamps 12 is more stable and less prone to displacement, and the eccentricity of the pipe fittings during the rotation welding of the metal pipe body 15 is avoided, thus preventing welding defects. In a favorable situation, the limiting rod 10 at one end of the support rod 9 extends through the strip-shaped through hole 23 on the surface of the gear disk 16 to the inner side of the arc-shaped limiting hole 21 on the surface of the transmission disk 19. This causes the second motor 17 to rotate, driving the drive disk 18 to rotate. The rotation of the drive disk 18 drives the drive belt body 22, which is fixedly mounted on one side of the transmission disk 19, to rotate. This causes the limiting rod 10 to move up and down within the strip-shaped through hole 23, causing the fixed wheel 13 at one end of the Y-shaped clamping block 12 to clamp the metal pipe body 15. This automatic centering effectively avoids the inaccurate centering caused by manual centering when clamping the pipe fitting.

[0021] like Figure 1 , Figure 2As shown, annular grooves are formed on the surfaces of the gear ring 3 and gear disk 16, and locking teeth are provided on the inner wall of the annular grooves. The first motor 7 is symmetrically installed on the top surface of the operating table 1. A transmission rod is fixedly installed at one end of the drive shaft of the first motor 7. Two drive gears 6 are installed on the surface of the transmission rod. The two drive gears 6 respectively engage with the locking teeth at the bottom of the gear ring 3 and gear disk 16. A support bearing seat is sleeved on the surface of the transmission rod. The combination of drive gears 6, first motor 7 and gear ring 3 and gear disk 16 facilitates the rotational welding of the metal pipe body 15.

[0022] like Figure 2 As shown, two fixed rotating rods 26 are symmetrically installed on the inner wall of the top of the mounting bracket 2. Two limiting rollers 25 are installed on the surface of the two fixed rotating rods 26. The bottom ends of the two limiting rollers 25 are respectively located inside the annular grooves opened on the surface of the gear ring 3 and the gear disk 16. The setting of the fixed rotating rods 26 and the limiting rollers 25 facilitates the limited rotation of the gear ring 3 and the gear disk 16.

[0023] like Figure 2 , Figure 4 As shown, a crossbar 14 is fixedly installed between the two Y-shaped clamping blocks 12. A U-shaped block 24 is fixedly installed at the center of the crossbar 14. A pressure sensing probe is installed at the center of the U-shaped block 24. One end of the pressure sensing probe is electrically connected to a pressure sensor. The arrangement of the U-shaped block 24 and the pressure sensing probe makes it easy for personnel to observe the force on the clamping mechanism holding the pipe fitting.

[0024] like Figure 1 , Figure 2 As shown, there are two first motors 7, which are located on both sides of the gear ring 3. The two first motors 7 are synchronous motors. By setting the two first motors 7 on both sides of the gear ring 3, it is convenient for the gear ring 3 and the gear disk 16 to rotate smoothly, which is beneficial for the rotation of the metal pipe body 15.

[0025] like Figure 1 , Figure 2 As shown, there are two sets of limiting rollers 25, which are located on the top sides of the gear ring 3 and the gear disk 16, respectively. By setting two sets of limiting rollers 25, it is convenient to limit the rotation of the gear ring 3 and the gear disk 16, which is conducive to the smooth rotation of the metal pipe body 15.
