[0001] This application relates to the field of welding technology, and in particular to a welding apparatus for flame cutting. Background Technology

[0002] In modern manufacturing, flame cutting machines, as efficient and precise cutting equipment, are widely used in the processing of metal sheets, profiles, and other materials. However, in the production process of flame cutting machines, further welding is often required on the cut parts to achieve purposes such as connection between parts, repair, or reinforcement of structural strength.

[0003] When welding components for flame cutting machines, existing welding equipment suffers from several limitations. Some designs are relatively fixed, making rapid adjustments to meet specific welding needs. For example, welding workpieces of different shapes, sizes, or angles often requires frequent manual changes of fixtures or adjustments to the equipment position, increasing operational complexity and significantly reducing production efficiency. Furthermore, some welding equipment lacks multi-axis drive capabilities, preventing free movement of the welding head in three-dimensional space and further limiting its application.

[0004] To address the aforementioned issues, a welding device for flame cutting is now designed. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] This application provides a welding device for flame cutting machine processing, which can solve the problem in the related art that when welding components of a flame cutting machine, some welding equipment designs are relatively fixed and it is difficult to quickly adjust them according to actual welding needs.

[0028] Please see Figures 1-3 A welding device for flame cutting machine processing includes: a base 1, on which a feeding platform 2 is provided, and a plurality of clamping members 3 are provided on the feeding platform 2, the clamping members 3 being used to fix the weldment;

[0029] A three-axis drive unit 4 is provided on the base 1, a laser welding head 5 is rotatably mounted on the three-axis drive unit 4, and a rotating part 6 is provided on the three-axis drive unit 4, the rotating part 6 being used to drive the laser welding head 5 to rotate.

[0030] The three-axis drive unit 4 includes an x-axis drive unit 41, a y-axis drive unit 42 disposed on the x-axis drive unit 41, and a z-axis drive unit 43 disposed on the y-axis drive unit 42. A mounting platform 7 is disposed on the z-axis drive unit 43, and the laser welding head 5 is rotatably disposed on the mounting platform 7.

[0031] The x-axis drive 41 is used to drive the y-axis drive 42 to move along the length of the base 1, the y-axis drive 42 is used to drive the z-axis drive 43 to move along the width of the base 1, and the z-axis drive 43 is used to drive the mounting platform 7 to move up and down.

[0032] The workpiece is placed on the feeding platform 2 on the base 1. Multiple clamping parts 3 on the feeding platform 2 firmly fix the workpiece on the feeding platform 2, ensuring that the workpiece will not move or shift during the welding process.

[0033] The x-axis drive unit 41 drives the y-axis drive unit 42 to move along the length of the base 1, thereby moving the entire y-axis and z-axis assembly and the laser welding head 5 in the x-axis direction. The y-axis drive unit 42 drives the z-axis drive unit 43 to move along the width of the base 1, realizing the movement of the laser welding head 5 in the y-axis direction. The z-axis drive unit 43 drives the mounting table 7 to rise and fall, thereby adjusting the height of the laser welding head 5 in the z-axis direction so that it can be accurately aligned with the welding position on the workpiece.

[0034] Once the laser welding head 5 is precisely moved to the welding position by the three-axis drive component 4, the laser welding head 5 is activated to perform the welding operation. At the same time, the rotating component 6 can drive the laser welding head 5 to rotate to adapt to the welding requirements of different angles on the workpiece.

[0035] Through the precise control of the three-axis drive component 4, the laser welding head 5 and the rotating component 6 can achieve high-precision positioning in three-dimensional space, ensuring the accuracy of the welding position. At the same time, the rotation function of the laser welding head 5 enables the welding device to adapt to the welding requirements of different angles on the workpiece, increasing the flexibility and diversity of welding, thereby reducing the need for manual intervention, reducing labor intensity, and improving welding speed and production efficiency.

[0036] This welding device is suitable for welding workpieces processed by flame cutting machine.

[0037] like Figure 4 and Figure 5 As shown, the feeding platform 2 in this embodiment includes a plurality of columns 21 arranged on the base 1, and a processing table 22 abutting between the tops of the plurality of columns 21. A drive motor 23 is provided on the base 1, and a turntable 24 is provided on the output shaft of the drive motor 23. The turntable 24 is connected to the bottom of the processing table 22.

[0038] Multiple columns 21 are fixed on the base 1, providing a stable support foundation for the processing table 22. The processing table 22 is placed between the tops of the multiple columns 21, and its upper surface serves as a working plane for placing the weldment, providing a flat and stable placement position for the weldment.

[0039] The drive motor 23 is mounted on the base 1 as a power source. When the machining table 22 needs to be rotated, the drive motor 23 starts, and its output shaft begins to rotate. The turntable 24 is fixedly connected to the output shaft of the drive motor 23 and rotates synchronously with the output shaft.

[0040] Since the turntable 24 is connected to the bottom of the processing table 22, the rotation of the turntable 24 will be transmitted to the processing table 22, thereby causing the processing table 22 and the welding parts placed on the processing table 22 to rotate together.

[0041] The turntable 24, driven by the drive motor 23, rotates the processing table 22, allowing the welding angle of the workpiece placed on the processing table 22 to be easily adjusted. During the welding process, welding can be performed at different positions of the workpiece without manually moving the workpiece or adjusting the welding equipment, greatly improving the flexibility and convenience of the welding operation.

[0042] The laser welding head 5 in this embodiment includes an optical focusing system, a protective gas nozzle, and a cooling system. It receives a laser beam from a laser generator and accurately projects it onto the workpiece to achieve the welding function. The optical system of the laser welding head 5 can precisely control the parameters of the laser beam, such as the spot size and power density, to meet the welding requirements of different workpieces. This is prior art and will not be described in detail here.

[0043] like Figure 4As shown, further, two support bars 221 are also arranged opposite each other on the processing table 22, and multiple positioning holes are opened on the support bars 221, with different hole diameters.

[0044] Two opposing support bars 221 provide an additional support surface for the weldment. When the weldment is placed on the processing table 22, the bottom of the weldment can partially or completely contact the support bars 221, increasing the stability of the weldment placement. Especially when the weldment is large and heavy, the support bars 221 can effectively prevent the weldment from shaking or tilting due to its own weight or external forces during the welding process.

[0045] The multiple positioning holes of different diameters on the support bar 221 provide diverse positioning methods for the weldment. For example, for some weldments with specific protrusions or holes, positioning holes that match the protrusions or holes of the weldment can be selected. By inserting positioning pins or other positioning elements, the weldment can be precisely fixed on the support bar 221, ensuring that the position of the weldment is accurate during the welding process.

[0046] The design of positioning holes with different diameters meets the positioning requirements of various specifications of weldments, enabling the weldments to be fixed in the most suitable way, and greatly improving the positioning accuracy of the weldments on the processing table 22.

[0047] The arrangement of positioning holes with various apertures allows the machining table 22 to adapt to a variety of weldments with different shapes, sizes and structures.

[0048] like Figure 4 and Figure 6 As shown, in one embodiment, the clamping member 3 includes a fixed platform 31 disposed on the processing table 22, an electric push rod 32 disposed inside the fixed platform 31, a fixed plate 33 disposed at the top of the piston rod of the electric push rod 32, and a quick clamp 34 disposed at the top of the fixed plate 33.

[0049] When no clamping operation is performed on the workpiece, the quick clamp 34 is in the released state, making it convenient to place the workpiece at the designated position on the processing table 22.

[0050] After placing the workpiece in a suitable position on the processing table 22, activate the electric push rod 32. The piston rod of the electric push rod 32 begins to extend or retract, pushing the fixed plate 33 upward or downward. As the fixed plate 33 rises or falls, the quick clamp 34 set on the top of the fixed plate 33 also rises or falls to a suitable height, approaching the part of the workpiece that needs to be clamped. Then operate the quick clamp 34 to clamp the workpiece.

[0051] The quick clamp 34 can provide a large clamping force to ensure that the workpiece remains stable during the subsequent welding process and will not move due to welding vibration or external force. This is existing technology and will not be described in detail here.

[0052] After welding is completed, first operate the quick clamp 34 to release the weldment. Then, activate the electric push rod 32 to extend the piston rod, which in turn moves the fixed plate 33 and the quick clamp 34 upwards, away from the weldment, to provide space for removing the weldment.

[0053] like Figure 2 and Figure 3 As shown, in one embodiment, the x-axis drive 41, y-axis drive 42, and z-axis drive 43 all include a housing 411. A lead screw 412 is rotatably disposed inside the housing 411. A sleeve 413 is threadedly connected to the outside of the lead screw 412. A traveling platform 414 is disposed on the sleeve 413. The traveling platform 414 is U-shaped. The housing 411 has corresponding moving holes. Both ends of the traveling platform 414 pass through the corresponding moving holes and extend to the outside of the housing 411. A threaded hole adapted to the lead screw 412 is disposed on the inner side of the sleeve 413.

[0054] A second drive motor 415 is mounted on the housing 411, and the output shaft of the second drive motor 415 is connected to one end of the lead screw 412. The travel platform 414 of the x-axis drive component 41 is connected to the housing 411 of the y-axis drive component 42, the travel platform 414 of the y-axis drive component 42 is connected to the housing 411 of the z-axis drive component 43, and the travel platform 414 of the z-axis drive component 43 is connected to the mounting platform 7.

[0055] After the drive motors 415 of each drive component (x-axis drive 41, y-axis drive 42, and z-axis drive 43) are started, their output shafts drive the lead screw 412 to rotate within the housing 411. Since the lead screw 412 is threadedly connected to the sleeve 413, when the lead screw 412 rotates, according to the principle of threaded transmission, the sleeve 413 will move axially along the lead screw 412. This movement of the sleeve 413 will drive the traveling platform 414 connected to it to move. The traveling platform 414 is U-shaped, with both ends passing through the moving holes on the housing 411 and extending outside the housing 411. Thus, the traveling platform 414 is guided by the moving holes during movement, ensuring the straightness and stability of the movement.

[0056] The traveling platform 414 of the x-axis drive unit 41 is connected to the housing 411 of the y-axis drive unit 42. When the drive motor 415 of the x-axis drive unit 41 drives the lead screw 412 to rotate, causing the traveling platform 414 to move along the x-axis direction, it will drive the y-axis drive unit 42 to move as a whole along the x-axis direction.

[0057] The travel platform 414 of the y-axis drive unit 42 is connected to the housing 411 of the z-axis drive unit 43. The drive motor 415 of the y-axis drive unit 42 drives the lead screw 412 to rotate, so that when the travel platform 414 moves along the y-axis direction, it will drive the z-axis drive unit 43 to move as a whole along the y-axis direction.

[0058] The travel platform 414 of the z-axis drive unit 43 is connected to the mounting platform 7. The drive motor 415 of the z-axis drive unit 43 drives the lead screw 412 to rotate, so that when the travel platform 414 moves along the z-axis direction, it will drive the mounting platform 7 to move along the z-axis direction.

[0059] like Figure 3 As shown, further, two slide rails 8 are arranged opposite each other inside the housing 411, and multiple sliders 9 are slidably arranged on the slide rails 8. The top of the sliders 9 is connected to the bottom of the traveling platform 414.

[0060] When the drive motor 415 drives the lead screw 412 to rotate, causing the sleeve 413 and the traveling table 414 to move, multiple sliders 9 at the bottom of the traveling table 414 will slide on the slide rail 8. The slide rail 8 provides precise guidance for the movement of the sliders 9, ensuring that the traveling table 414 can only move in a straight line along the axial direction of the lead screw 412, that is, the corresponding x-axis, y-axis or z-axis, thus avoiding deviation or shaking of the traveling table 414 during movement.

[0061] The cooperation between slider 9 and slide rail 8 not only serves as a guide but also provides additional support for the traveling table 414. When the traveling table 414 is carrying a certain weight of laser welding head 5 or other equipment, slider 9 transfers part of the weight to slide rail 8, reducing the load on lead screw 412 and sleeve 413 and improving the stability and reliability of the entire drive structure.

[0062] like Figure 2 As shown, in one embodiment, the mounting platform 7 is L-shaped, the rotating component 6 includes a mounting disk 61 rotatably disposed on one side of the mounting platform 7, and a drive motor 62 and a reducer 63 disposed on the other side of the mounting platform 7. The laser welding head 5 is disposed on the mounting disk 61, the output shaft of the drive motor 62 is connected to the input shaft of the reducer 63, and the output shaft of the reducer 63 is connected to the mounting disk 61.

[0063] When the laser welding head 5 needs to be rotated, the drive motor 62 is started. The output shaft of the drive motor 62 begins to rotate, transmitting power to the input shaft of the connected reducer 63. The reducer 63 reduces the speed and increases the torque of the input power. Through the gear transmission mechanism inside the reducer 63, the speed of the output shaft is reduced while the torque of the output shaft is increased to meet the power requirements for rotating the mounting plate 61 and the laser welding head 5. The output shaft of the reducer 63 transmits the processed power to the mounting plate 61, causing the mounting plate 61 to rotate around its axis.

[0064] Since the laser welding head 5 is mounted on the mounting plate 61, when the mounting plate 61 rotates, it will drive the laser welding head 5 to rotate as well. This allows the welding angle of the laser welding head 5 to be adjusted according to the requirements of the welding process, enabling precise welding of different positions on the workpiece.
