[0002] With the development of industrial automation and precision manufacturing technology, the requirements for material joining technology are increasing. Especially when welding some profiles, the limitations of traditional manual electric welding in meeting the high-precision and high-efficiency welding requirements are gradually becoming apparent. As a new type of welding method, laser welding technology, with its advantages of high energy density, high precision, high speed and good welding quality, has gradually become a research hotspot and development direction in the field of industrial welding.

[0003] In existing laser welding technology, the profile is usually clamped by a chuck before welding. However, due to the profile's own weight, the ordinary chuck is prone to shaking when rotating the profile, which can lead to unstable welding or even cracking of the weld joint. Utility Model Content

[0004] The main purpose of this invention is to propose a laser welding device that aims to solve the problems of unstable welding and even weld cracking caused by the shaking of the profile during the welding process in the prior art.

The welding device is located between the fixtures and is used to weld the profile on the fixture. The fixtures are equipped with claws on both sides, which allows the fixtures to clamp more of the profile, making the profile more stable during rotation and reducing the problem of shaking of the profile during rotation due to insufficient clamping length.

[0033] like Figures 1 to 9As shown, a laser welding device includes: a worktable 1, on which multiple clamps 2 and welding devices 3 are provided. The multiple clamps 2 are arranged along the Y-axis and are rotatably connected to the worktable 1. The welding devices 3 are disposed between the multiple clamps 2. The clamps 2 are provided with multiple first jaws 21 and multiple second jaws 22. The first jaws 21 and the second jaws 22 are respectively disposed on both sides of the clamps 2 and are movably connected to the clamps 2.

[0034] The clamp 2 is rotatably connected to the worktable 1, which facilitates the clamp 2 to drive the profile 4 to rotate for welding, thus improving the welding flexibility. The welding device 3 is located between the clamps 2 and is used to weld the profile 4 on the clamp 2. The clamp 2 is provided with claws on both sides, which allows the clamp 2 to clamp more positions of the profile 4, making the profile 4 more stable during rotation and reducing the problem of the profile 4 shaking when rotating due to insufficient clamping length.

[0035] like Figure 2 As shown, the worktable 1 is set along the Y-axis. Two clamps 2 are provided on both sides of the worktable 1. The two clamps 2 are hollow cylinders that allow the profile 4 to pass through and be clamped, thus stabilizing the profile 4. A welding device 3 is located between the two clamps 2, with its support far from the clamps 2, allowing sufficient space to weld the profile 4 between the clamps 2 without affecting the rotation and movement of the profile. Four first jaws 21 and four second jaws 22 are provided on each side of the clamps 2 along the Y-axis. These four jaws conveniently clamp the four sides of the profile 4, stabilizing it.

[0036] In some specific embodiments, the clamp 2 is provided with a chuck 23 and a synchronous wheel 24. The chuck 23 and the synchronous wheel 24 are fixedly connected to both sides of the clamp 2 along the Y-axis. The worktable 1 is provided with a rotation drive device 11, which is located on one side of the synchronous wheel 24 and is rotatably connected to the synchronous wheel 24. The first jaw 21 is movably connected to the chuck 23 and is arranged around the chuck 23. The second jaw 22 is movably connected to the synchronous wheel 24 and is arranged around the synchronous wheel 24.

[0037] A synchronous wheel 24 is provided on one side of the clamp 2. The synchronous wheel 24 can not only drive the entire clamp to rotate, making it convenient for the profile 4 to rotate, but also has a second claw 22 on the synchronous wheel 24 to clamp the profile 4. It can work together with the first claw 21 on the chuck 23 on the other side to clamp the profile 4 and keep the welding position of the profile 4 stable.

[0038] like Figure 9As shown, the synchronous wheel 24 is a hollow disc. A servo motor is mounted on the X-axis of the synchronous wheel 24 as a rotation drive device 11. A conveyor belt is installed at the output end of the servo motor and is connected to the synchronous wheel 24 for transmission. When the servo motor rotates, it drives the synchronous wheel 24 to rotate, and then drives the entire clamp 2 to rotate, causing the profile 4 on the clamp 2 to rotate. The four second jaws 22 on the synchronous wheel 24 are provided with elongated channels. These channels can connect with the through holes on the plane of the synchronous wheel 24. By moving the docking position of the elongated channels and the through holes, the clamping distance between the second jaws 22 can be adjusted.

[0039] In some specific embodiments, the chuck 23 includes a first turntable 231 and a second turntable 232. The first turntable 231 is provided with a plurality of first grooves 2311, a first gear 2312 and a plurality of clearance notches 2313. The first grooves 2311 extend along the axial direction of the first turntable 231 and gradually approach the axial direction of the first turntable 231. The first grooves 2311 are circumferentially distributed on the first turntable 231 and all extend in a clockwise or counterclockwise direction. The first gear 2312 and the clearance notches 2313 are located around the first turntable 231. The second turntable 232 is provided with multiple second slide grooves 2321, a second gear 2322 and multiple clearance grooves 2323. The second slide grooves 2321 extend along the axis of the second turntable 232 and gradually approach the axis of the second turntable 232. The multiple second slide grooves 2321 and clearance grooves 2323 are circumferentially distributed on the second turntable 232 and extend in a clockwise or counterclockwise direction. The second gear 2322 is located around the second turntable 232. The axes of the first turntable 231 and the second turntable 232 coincide and the first slide grooves 2311 and the second slide grooves 2321 are staggered, so that the first slide groove 2311 and the clearance groove 2323 are opposite to each other, and the second slide groove 2321 and the clearance notch 2313 are opposite to each other. The first chuck 21 is respectively located in the first slide groove 2311 and the second slide groove 2321. The chuck 23 is provided with two control gears 25. The two control gears 25 are rotatably connected to the chuck 23. The two control gears 25 are respectively meshed with the first gear 2312 and the second gear 2322.

[0040] The first turntable 231 and the second turntable 232 have their axes coincident, and the first slide groove 2311 and the clearance groove 2323, and the second slide groove 2321 and the clearance notch 2313 are misaligned, so that the entire chuck 23 structure achieves a more compact layout in a limited space. The control gear 25 can drive the first gear 2312 and the second gear 2322 to rotate, thereby driving the first chuck 21 on the chuck 23 to move and perform opening and closing movements. The meshing of the control gear 25 with the first gear 2312 and the second gear 2322 can ensure the smooth operation of the first chuck 21.

[0041] like Figure 3-7 As shown, the chuck 23 is composed of a first turntable 231 and a second turntable 232 overlapping along the Y-axis. The turntables are hollow. There are two first grooves 2311 on the surface of the first turntable 231, which are symmetrically arranged. Two clearance notches 2313 are located on the circumference of the first turntable 231 and are symmetrically arranged. The first gear 2312 is located on one side of the circumference of a certain first groove 2311.

[0042] Similarly, the second turntable 232 is hollow, and the surface of the second turntable 232 is provided with two second sliding grooves 2321 and two clearance grooves 2323. The two second sliding grooves 2321 are symmetrically arranged, and the two clearance grooves 2323 are symmetrically arranged. The second gear 2322 is located on one side of the circumference of a certain second sliding groove 2321.

[0043] The first turntable 231 and the second turntable 232 are staggered, and the four first jaws 21 are slidably installed in the two first sliding grooves 2311 and the two second sliding grooves 2321 respectively, so that the four first jaws 21 can be staggered. The first gear 2312 and the second gear 2322 are connected end to end. The staggered arrangement of the first sliding grooves 2311 and the second sliding grooves 2321 is spiral. When the first turntable 231 and the second turntable 232 are rotated, the four first jaws 21 can move closer and further apart to achieve the clamping function. An outer shell is provided on the outside of the chuck 23 to cover the first turntable 231 and the second turntable 232 to protect the internal structure and expose the first jaws 21. Two control gears 25 are rotatably connected to one side inside the outer shell, and a rotation hole is left on the outer shell. The control gears 25 are installed in the rotation hole. The control gears 25 can be rotated through the rotation hole, thereby rotating the first turntable 231 and / or the second turntable 232 to achieve the clamping function of the chuck 23.

[0044] In some specific embodiments, the workbench 1 is provided with multiple rotating frames 12, which are fixedly installed on the workbench 1. The multiple rotating frames 12 are arranged along the Y-axis direction, and the clamp 2 passes through the rotating frame 12 and is rotatably connected to the rotating frame 12.

[0045] On the one hand, the rotating frame 12 can connect the fixture to the workbench 1; on the other hand, the fixture 2 is rotatably connected to the rotating frame 12, which facilitates the rotation of the fixture 2 and makes the welding process more flexible.

[0046] Two rotating frames 12 are provided, and they are also hollow. The clamp 2 can be inserted into the rotating frame 12. A row of rolling balls is installed on one ring of the clamp 2. The rolling balls contact the rotating frame 12 to form a bearing structure, so that the clamp 2 can rotate relative to the rotating frame 12.

[0047] Furthermore, a protective plate is also installed on the side of the rotating frame 12 near the welding device 3. The protective plate extends along the X-axis and Z-axis directions. The protective plate can prevent debris from splashing during welding and protect the safety of equipment such as motors.

[0048] In some specific embodiments, the workbench 1 is provided with a welding stabilizing device 13, which includes a stabilizing drive device 131 and a stabilizing clamp 132. The output end of the stabilizing drive device 131 is arranged along the X-axis direction, and the output end of the stabilizing drive device 131 is connected to the stabilizing clamp 132 in a transmission connection.

[0049] The welding stabilizing device 13 further enhances the stability of the welding process, prevents the profile 4 from shaking during welding, reduces welding defects caused by the positional shift or shaking of the profile 4, and thus improves the welding quality.

[0050] like Figure 2 , 7 As shown, the welding stabilizing device 13 is located between the two clamps 2, and its bottom is fixedly connected to the workbench 1. The upper side is equipped with a stabilizing drive device 131, which is a cylinder. The cylinder drive direction is set along the X-axis direction. The drive side is equipped with a stabilizing clamp 132, which is a long plate. The height of the plate is just flush with the profile 4. The contact position between the long plate and the profile 4 is arc-shaped, which can make the pipe or profile 4 stuck in the arc.

[0051] In some specific embodiments, the welding device 3 includes a welding laser head 31, a first welding drive device 32, and a second welding drive device 33. The output end of the first welding drive device 32 is arranged along the X-axis direction, and the output end of the first welding drive device 32 is connected to the second welding drive device 33 in a driving connection, so that the first welding drive device 32 can drive the second welding drive device 33 to move along the X-axis direction. The output end of the second welding drive device 33 is arranged along the Z-axis direction, and the drive output end of the second welding drive device 33 is connected to the welding laser head 31 in a driving connection.

[0052] Welding device 3 can adapt to various welding path requirements, improving the equipment's adaptability to different types of workpieces. It can accurately align the laser focus with the weld position, ensuring the stability of welding quality.

[0053] The bottom of the welding device 3 is a support frame for supporting the welding head. The first welding drive device 32 is located at the top of the welding device 3. The first drive device is a cylinder and its height is higher than the height of the clamping profile 4, so that the welding laser head 31 has a certain amount of movement space. The second welding drive device 33 is also a cylinder. After the welding laser head 31 is connected to the second welding drive device 33, the first welding drive device 32 can drive the second welding drive device 33 to move along the X-axis, so that the welding laser head 31 can weld along the X-axis. The second welding drive device 33 can make the welding laser head 31 move along the Z-axis, which is convenient for welding profiles 4 of different sizes.

[0054] In some specific embodiments, the workbench 1 is provided with conveyor frames 14 on both sides, and the conveying direction of the conveyor frames 14 is set along the Y-axis direction.

[0055] The conveyor frame 14 facilitates the continuous transport of the profile 4, ensuring that the welding laser head 31 can be accurately aligned with the weld position.

[0056] like Figure 1 As shown, the conveyor frame 14 is located on both sides of the workbench 1, and multiple sets of rollers are arranged on the conveyor frame 14 along the Y-axis to facilitate the conveying of the profile 4.

[0057] In some specific embodiments, the clamp 2 is provided with a quick clamp 15, which is fixedly installed on the clamp 2. The quick clamp 15 is provided with a clamp body 151 and a pressure rod 152. The clamp body 151 and the pressure rod 152 are hinged together. The clamp body 151 is located on the side closer to the profile 4, and the pressure rod 152 is located on the side away from the profile 4.

[0058] like Figure 8 As shown, the quick clamp 15 can firmly fix the profile 4 on the clamp 2, preventing the profile 4 from shifting due to vibration or welding stress during the welding process, thereby ensuring the stability of the welding quality.

[0059] In some specific embodiments, pulleys 26 are mounted on the first jaw 21 and the second jaw 22.

[0060] The use of pulley 26 transforms the sliding friction between the jaws and the clamp 2 into rolling friction, greatly reducing the wear of the jaws on the profile 4.

[0061] In some specific embodiments, the first claw 21 and / or the second claw 22 protrude along the Y-axis direction.

[0062] The claws protrude to one side, making the clamping range of the profile 4 longer and the clamping more stable.

[0063] The first jaw 21 protrudes along the Y-axis, extending the clamping length of the chuck 23 and making the profile 4 clamped more stably.

[0064] The workflow of this utility model is as follows: Two profiles 4 to be welded are placed on the conveyor frame 14 and conveyed to the workbench 1 by the conveyor belt. After aligning the required welding positions, the first jaw 21 and the second jaw 22 are operated to clamp the profiles 4, and the quick clamp 15 is adjusted to squeeze the profiles 4 to further stabilize them. Then, the welding stabilizing device 13 is driven to hold the profiles 4 against it, fixing them in multiple directions. After the profiles 4 are fixed, the welding device 3 is started, and the welding height position is adjusted using the second welding drive device. Then, the first welding drive device is turned on to drive the welding laser head 31 to move along the X-axis to weld one side of the profiles 4. After welding one side, the stabilizing clamp 132 on the welding stabilizing device 13 is driven away from the profiles 4. The two rotation drive devices 11 are started to drive the two synchronous wheels 24 to rotate simultaneously. The synchronous wheels 24 drive the clamp 2 to rotate, and the other side to be welded is moved. The stabilizing clamp 132 is driven to hold the profiles 4 against it, and the welding is repeated. After the profile 4 is welded, release the quick clamp 15, the stabilizing clamp 132 and the clamp 2, and take the profile 4 out from one side along the conveyor frame 14.

[0065] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
