Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to a laser welding device for pipe welding. Background Technology

[0002] Pipeline welding technology is a core process in the fields of oil and gas transportation, chemical industry, power industry and municipal engineering, involving a variety of methods such as electric arc welding (SMAW, GTAW, GMAW), submerged arc welding (SAW) and high-energy beam welding (laser / electron beam).

[0003] A search revealed CN206527484U, which discloses a positioning device for pipe assembly welding. This device includes a first frame, a second frame, and axial clearance adjusting bolts. The first and second frames are annular and connected by a plurality of axial clearance adjusting bolts. The first frame has a plurality of first radial fastening bolts that penetrate the first frame and are threaded to it. The second frame has a plurality of second radial fastening bolts that penetrate the second frame and are threaded to it. Using this positioning device for pipe assembly welding ensures pipe assembly accuracy and improves welding quality.

[0004] However, current pipe welding methods make it difficult to clean the bevel of the weld area after it is clamped and positioned, resulting in dust remaining at the bevel when welding, which affects the quality of the weld. Utility Model Content

[0005] The purpose of this invention is to provide a laser welding device for pipe welding, in order to overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes two fixed rings with a gap between them. Each of the two fixed rings is provided with an electric slide rail. Two sliding members are slidably connected within the two electric slide rails. Each sliding member is fixedly connected to a connecting plate via a connecting rod. An electric telescopic rod is provided on the connecting plate, with its output end penetrating the connecting plate. A welding head is provided on the output end of the electric telescopic rod. A connecting member is provided on one side of the connecting plate, and a wiping member is provided on the connecting member.

[0007] Furthermore, both of the fixing rings are fixedly mounted on a mounting shell, and two hydraulic telescopic rods are provided inside the mounting shell. Each of the two hydraulic telescopic rods has a support plate at its output end, and each of the two support plates has two support rods at its top. Each of the four support rods has a first arc-shaped plate at its top.

[0008] Furthermore, a pipe fitting is placed on top of every two first arc-shaped plates, and both pipe fittings are provided with bevels, with the two bevels being positioned correspondingly.

[0009] Furthermore, the mounting shell is provided with two fixing rods, and each of the two fixing rods is provided with a second arc-shaped plate at its bottom. The two second arc-shaped plates are respectively located near the middle of each pair of pipe fittings.

[0010] Furthermore, the mounting shell is provided with two spring telescopic components, and each of the two spring telescopic components has a slanted block on its output end.

[0011] Furthermore, each of the two inclined blocks is provided with an inclined surface, the inclined surfaces of the two inclined blocks are far apart from each other, and the two inclined blocks correspond one-to-one with the positions of the two pipe fittings.

[0012] Compared with the prior art, the laser welding equipment for pipe welding provided by this utility model prevents two pipe fittings from falling off the first arc plate due to excessive position adjustment by limiting the two inclined blocks. After the position adjustment is completed, the first and second arc plates enable the device to clamp pipe fittings of different diameters. After the two pipe fittings are clamped, the electric telescopic rod is activated to drive the welding head to weld. At the same time, when the connecting plate moves, it can drive the wiping component to move, so that impurities and dust on the welding area before welding can be wiped off, preventing dust from affecting the welding quality before welding.

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] Please see Figure 1-3 This utility model provides a laser welding device for pipe welding, comprising two fixed rings 1 with a gap between them. Each of the two fixed rings 1 is provided with an electric slide rail 2. Two sliding members 3 are slidably connected within the two electric slide rails 2. Each sliding member 3 is fixedly connected to a connecting plate 5 via a connecting rod 4. An electric telescopic rod 6 is provided on the connecting plate 5, with its output end penetrating the connecting plate 5. A welding head 7 is provided on the output end of the electric telescopic rod 6. A connecting member 8 is provided on one side of the connecting plate 5. A wiping component 9 is provided on the 8. The electric telescopic rod 6 drives the welding head 7 to move, so that the welding head 7 reaches the welding position. Then, the electric slide rail 2 drives the two sliding components 3 to move, so that the two connecting rods 4 move, so that the connecting plate 5 moves, so that the electric telescopic rod 6 moves, so that the welding head 7 moves, so that the welding head 7 can start welding the bevel connection of the two pipe fittings 15. At the same time, when the connecting plate 5 moves, it can drive the connecting component 8 to move, so that the wiping component 9 can move, so that impurities and dust on the welding point before welding can be wiped away, preventing dust from affecting the welding quality before welding.

[0020] Preferably, both of the two fixing rings 1 are fixedly mounted on a mounting shell 10. Two hydraulic telescopic rods 11 are disposed inside the mounting shell 10. Each of the two hydraulic telescopic rods 11 has a support plate 12 at its output end. Each of the two support plates 12 has two support rods 13 at its top. Each of the four support rods 13 has a first arc-shaped plate 14 at its top. A pipe fitting 15 is placed on top of every two first arc-shaped plates 14. Both pipe fittings 15 have bevels, and the two bevels are positioned correspondingly. Two fixing rods 16 are disposed on the mounting shell 10. Each of the fixed rods 16 has a second arc-shaped plate 17 at its bottom. The two second arc-shaped plates 17 are located near the middle of each pair of pipe fittings 15. Activating the two hydraulic telescopic rods 11 moves the support plate 12 upward, causing the four support rods 13 to move upward, which in turn moves the four first arc-shaped plates 14 upward, causing the two pipe fittings 15 to move upward. This causes the tops of the two pipe fittings 15 to abut against the two second arc-shaped plates 17, thus clamping the two pipe fittings 15. The arrangement of the first arc-shaped plates 14 and the second arc-shaped plates 17 enables this configuration to clamp pipe fittings 15 of different diameters.

[0021] Preferably, the mounting shell 10 is provided with two spring telescopic members 18, and each of the two spring telescopic members 18 is provided with a slanted block 19 at its output end. Each of the two slanted blocks 19 is provided with a slanted surface, and the slanted surfaces of the two slanted blocks 19 are far apart from each other. The two slanted blocks 19 correspond one-to-one with the positions of the two pipe fittings 15. By pushing the two pipe fittings 15 toward the mounting shell 10 from the positions of the two slanted blocks 19, each pipe fitting 15 is placed on the two first arc-shaped members. Due to the movement of the pipe fittings 15, the slanted blocks 19 no longer contact the pipe fittings 15, causing the two spring telescopic members 18 to reset, and the two slanted blocks 19 to reset. At this time, when the two pipe fittings 15 are adjusted for welding position, the limiting effect of the two slanted blocks 19 prevents the two pipe fittings 15 from falling off the first arc-shaped plate 14 due to excessive position adjustment.

[0022] Working principle: By pushing the two pipe fittings 15 towards the mounting shell 10 from the positions of the two inclined blocks 19, each pipe fitting 15 is placed on the two first arc-shaped parts. Due to the movement of the pipe fittings 15, the inclined blocks 19 are no longer in contact with the pipe fittings 15, causing the two spring telescopic parts 18 to reset, and the two inclined blocks 19 to reset. At this time, when the welding position of the two pipe fittings 15 is adjusted, the limiting of the two inclined blocks 19 prevents the two pipe fittings 15 from falling off the first arc-shaped plate 14 due to excessive position adjustment. After the position adjustment is completed, the two hydraulic telescopic rods 11 are activated to drive the support plate 12 to move upward, causing the four support rods 13 to move upward, driving the four first arc-shaped plates 14 to move upward, causing the two pipe fittings 15 to move upward, causing the tops of the two pipe fittings 15 to abut against the two second arc-shaped plates 17 one by one, so that the two pipe fittings 15 are clamped. The setting of the first arc-shaped plates 14 and the second arc-shaped plates 17 enables this setting to clamp pipe fittings 15 of different diameters.

[0023] After the two pipe fittings 15 are clamped, the electric telescopic rod 6 is activated to move the welding head 7 to the welding position. Then, the electric slide rail 2 moves the two sliding parts 3, which in turn moves the two connecting rods 4, which in turn moves the connecting plate 5. This causes the electric telescopic rod 6 to move, which in turn moves the welding head 7, allowing the welding head 7 to begin welding the bevel joint of the two pipe fittings 15. At the same time, the movement of the connecting plate 5 moves the connecting parts 8, which in turn moves the wiping parts 9, allowing impurities and dust on the welding area to be wiped away before welding, preventing dust from affecting the welding quality.

[0024] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
