Description

Technical Field

[0001] This application relates to the field of laser welding technology, and in particular to a welding auxiliary device. Background Technology

[0002] Currently, laser welding is widely used in various industries, especially in the rail transportation sector. Laser welding ensures the appearance and sealing of weld seams, exhibits less deformation compared to traditional welding, and improves welding efficiency. However, laser welding differs slightly from traditional welding methods. When welding long butt welds, handheld laser welding torches cannot maintain a straight line of movement, resulting in arc deviation. To ensure weld quality, the welding torch must be controlled to move in a straight line.

[0003] However, etching and punching methods cannot effectively solve the above problems. Welders often need to weld multiple short welds, stopping after each short weld before continuing with the next, thus completing the long weld. This not only affects welding efficiency but also weld quality, which has always been a major challenge for handheld laser welding guns. Utility Model Content

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] In a first aspect, this utility model provides a welding auxiliary device, including a guide assembly, a clamping assembly, and a connecting assembly. A welding torch is fixed to the clamping assembly, and the connecting assembly is connected to the clamping assembly and moves linearly along the guide assembly. The guide assembly includes a base plate and two side plates, with the two side plates disposed opposite to each other on the base plate. Each side plate has a through groove formed therein, the through groove extending along the length direction of the side plate, and the connecting assembly passes through the through grooves of the two side plates and moves along the through grooves.

[0007] Furthermore, the connecting assembly includes a movable shaft, bearings, and a baffle. The movable shaft passes through the two through slots, and a bearing is installed at each end of the movable shaft. One end is connected to the clamping assembly, and the other end is connected to the baffle so that the bearing can move along the extension direction of the through slot.

[0008] Furthermore, there are multiple movable shafts, which are evenly distributed along the extension direction of the through groove.

[0009] Furthermore, the guide assembly includes a radiation absorbing plate disposed on the side plate near the clamping assembly, and the material of the radiation absorbing plate includes lead-boron polyethylene.

[0010] Furthermore, the guide assembly includes a suction cup, which is mounted on the bottom of the base plate to secure the base plate.

[0011] Furthermore, the clamping assembly includes a base, a clamping part, and a positioning pin.

[0012] Furthermore, the clamping assembly also includes a fixing block, which is mounted on the base and disposed opposite to the side wall of the base; a first through hole is formed on the side wall, and a second through hole is formed on the fixing block, and the positioning pin passes through the first through hole and the second through hole to engage with the base.

[0013] Furthermore, the clamping part includes a fixed plate, a vertical plate, and a clamp. The fixed plate is placed in the positioning groove, and the positioning pin abuts against the fixed plate. The vertical plate is vertically fixed to the fixed plate, and the clamp is installed on the top of the vertical plate to clamp the welding gun.

[0014] Furthermore, the number of the upright plates is two, and the two upright plates are arranged opposite to each other; the clamp includes two clamping plates, one of which is fixed to the top of each upright plate.

[0033] like Figure 1 , Figure 2 As shown, this application provides a welding auxiliary device, including a guide assembly, a clamping assembly, and a connecting assembly. The welding torch is fixed on the clamping assembly, and the connecting assembly is connected to the clamping assembly and moves linearly on the guide assembly. The guide assembly includes a base plate 11 and two side plates 12, with the two side plates 12 arranged opposite to each other on the base plate 11. Each side plate 12 has a through groove 121 formed thereon, which extends along the length of the side plate 12. The connecting assembly passes through the through grooves 121 of the two side plates 12 and moves along the through grooves 121.

[0034] In this embodiment, the connecting component connects the clamping component and the guiding component, and moves along the through groove 121 of the guiding component, thereby enabling the clamping component to also move along the extension direction of the through groove 121. Two opposing side plates 12 are each provided with a through groove 121, which extends along the length of the side plate 12. The two through grooves 121 are also opposite to each other, so that the connecting component can pass through the two through grooves 121 and move along the through grooves 121.

[0035] In this embodiment, the welding torch is fixed to the clamping assembly and moves along the through groove 121 with the clamping assembly. When the welding torch is aligned with the weld seam, the clamping assembly drives the welding torch to move in a straight line, causing the nozzle of the welding torch to move along the weld seam, thereby avoiding arc deviation, enhancing weld quality, and improving welding efficiency. The above-mentioned welding auxiliary device can control the movement direction of the welding torch, keeping it moving in a straight line during the welding process, and efficiently achieving the welding of long weld seams; it is simple to install and disassemble, low in cost, and highly practical.

[0036] In some embodiments, the connecting assembly includes a movable shaft 21, a bearing 22, and a baffle 23. The movable shaft 21 passes through two through slots 121. A bearing 22 is installed at each end of the movable shaft 21, and one end is connected to the clamping assembly, while the other end is connected to the baffle 23 to allow the bearing 22 to move along the extension direction of the through slot 121.

[0037] Reference Figure 1 The movable shaft 21 passes through two through slots 121, and bearings 22 are respectively installed at both ends of the movable shaft 21, allowing it to move along the through slots 121. After passing through the bearings 22, one end of the movable shaft 21 is connected to a clamping assembly to facilitate the movement of the clamping assembly, and the other end is connected to a baffle 23 to prevent the bearings 22 from detaching from the through slots 121. In this embodiment, the connecting assembly has a simple structure, is easy to assemble and disassemble, and is convenient to use.

[0038] Furthermore, there are multiple movable shafts 21, which are evenly distributed along the extension direction of the through groove 121. Understandably, the multiple movable shafts 21, together with multiple bearings 22, can make the connection between them and the clamping assembly more secure, and the movement of the overall structure more stable.

[0039] In some embodiments, the guide assembly includes a radiation absorbing plate 13 disposed on a side plate 12 near the clamping assembly, and the material of the radiation absorbing plate 13 includes lead-boron polyethylene.

[0040] In this embodiment, the shape of the radiation absorbing plate 13 can be set to be the same as that of the side plate 12, that is, the radiation absorbing plate 13 is provided with the same through groove 121, thereby avoiding affecting the movement of the clamping assembly driven by the connecting assembly. The radiation absorbing plate 13 is installed on the side plate 12 near the clamping assembly and is installed on the outside of the side plate 12. The material of the radiation absorbing plate 13 includes lead-boron polyethylene, which can absorb the radiation generated during welding, reduce the hazards of welding operations, and reduce reflectivity, so as to reduce machine errors and machine damage caused by excessive reflected light in the welding machine.

[0041] In some embodiments, the guide assembly includes a suction cup 14, which is mounted on the bottom of the base plate 11 to fix the base plate 11. In this embodiment, a suction cup 14 is provided on the bottom of the base plate 11 of the guide assembly to fix the base plate 11 in the required position and prevent it from moving when the welding torch travels. There can be multiple suction cups 14, distributed on the bottom surface of the base plate 11. The multiple suction cups 14 are evenly distributed.

[0042] In some embodiments, the clamping assembly includes a base 31, a clamping part 32, and a positioning pin 33. A positioning groove 311 is formed on the base 31, the clamping part 32 is placed in the positioning groove 311, the welding torch is fixed to the clamping part 32, and the positioning pin 33 is engaged with the base 31 and abuts against the clamping part 32. (See reference...) Figure 2 , Figure 3 The positioning groove 311 on the base 31 is used to place the clamping part 32 and prevent the clamping part 32 from sliding on the base 31 when the clamping assembly moves. The two ends of the positioning pin 33 are respectively installed on the base 31, the positioning pin 33 is engaged with the base 31, and one side of the positioning pin 33 abuts against the clamping part 32, which can further fix the clamping part 32 and prevent it from shifting during the movement of the base 31.

[0043] Specifically, the clamping assembly also includes a fixing block 34, which is mounted on the base 31 and disposed opposite to the side wall of the base 31. A first through hole 312 is formed on the side wall, and a second through hole 341 is formed on the fixing block 34. A positioning pin 33 passes through the first through hole 312 and the second through hole 341 and engages with the base 31. In this embodiment, the fixing block 34 is mounted on the base 31 and disposed opposite to the side wall of the base 31. One end of the positioning pin 33 passes through the first through hole 312 on the side wall, and the other end passes through the second through hole 341 on the fixing block 34, thereby engaging with the base 31. Inserting and removing the positioning pin 33 allows for easy replacement of the clamping part 32, enabling adaptation to different welding torches.

[0044] One side of the positioning pin 33 abuts against the clamping part 32 to prevent the clamping part 32 from shifting on the base 31.

[0045] In some embodiments, the clamping part 32 includes a fixing plate 321, a vertical plate 322, and a clamp. The fixing plate 321 is placed in the positioning groove 311, and the positioning pin 33 abuts against the fixing plate 321. The vertical plate 322 is vertically fixed to the fixing plate 321, and the clamp is installed on the top of the vertical plate 322 to clamp the welding torch. In this embodiment, the fixing plate 321 is placed in the positioning groove 311 and abuts against the positioning pin 33, so that the clamping part 32 is in a stable state on the base 31. The clamping part 32 is easy to install on the base 31 and is also easy to disassemble, allowing different clamping parts 32 to be replaced to adapt to different welding torches. The vertical plate 322 is vertically arranged on the fixing plate 321, which allows the position of the clamp to be higher than the positions of the fixing plate 321 and the positioning pin 33, so as to avoid interference when fixing the welding torch.

[0046] Furthermore, there are two upright plates 322, which are arranged opposite to each other. The clamp includes two clamping plates 323, with one clamping plate 323 fixed to the top of each upright plate 322. The clamping plates 323 are arc-shaped, and the two clamping plates 323 are arranged opposite to each other, with the welding torch clamped between the two clamping plates 323. In this embodiment, two upright plates 322 are arranged opposite to each other on the fixed plate 321, and a clamping plate 323 is provided at the top of each upright plate 322. The two clamping plates 323 clamp the welding torch, resulting in a simple structure. To match the shape of the welding torch, the clamping plates 323 are arc-shaped, and the two clamping plates 323 clamp the welding torch opposite to each other. The welding torch can be easily installed by being held between the two arc-shaped clamping plates 323.

[0047] In some embodiments, the clamping part 32 further includes a stiffener 324, which is disposed between the upright plate 322 and the fixed plate 321. A stiffener 324 is provided on each of the two upright plates 322 on opposite sides to support the upright plates 322. Understandably, the stiffener 324 can further support the upright plates 322 and, together with the upright plates 322, bear the weight of the welding torch. (Refer to...) Figure 2 Two upright plates 322 are arranged opposite each other, and stiffening plates 324 are installed on the opposite sides of the two upright plates 322. The stiffening plates 324 are fixed between the fixed plate 321 and the upright plates 322, and are triangular plates, which can provide more support for the upright plates 322.

[0048] The welding auxiliary device of this application embodiment is applied to laser welding and can ensure that the welding torch travels stably in a straight line during the welding process, and efficiently weld long weld seams.
