[0029] Embodiment 1:

[0030] refer to Figure 1 The utility model provides a laser welding head 6 fixing fixture for high-strength steel rolling equipment, which is integrally installed on the bottom column 7 of the rolling line. The fixing fixture includes a connecting plate 1, a transverse mounting bracket 2, a longitudinal mounting bracket 3, a connecting piece 4 and an adjusting mounting mechanism 5.

[0031] Specifically, refer to Figure 1The upper surface of the connecting plate 1 is fixed to the front bottom of the horizontal mounting bracket 2 by bolts (the front end refers to the end close to the bottom column 7, and the rear end refers to the end away from the bottom column 7). The side surfaces of the connecting plate 1 and the horizontal mounting bracket 2 are also fastened and reinforced by connecting members 4, and the lower surface of the connecting plate 1 is fixedly connected to the bottom column 7 by bolts.

[0032] refer to Figure 1 A connecting plate 1 is fixed to the bottom of the front end of the transverse mounting bracket 2, and two longitudinal mounting brackets 3 are installed at the rear end.

[0033] The longitudinal mounting bracket 3 is detachably connected to the transverse mounting bracket 2 via a connecting piece 4. The longitudinal mounting bracket 3 is used to support and position the laser welding head 6 so that it can perform welding at a desired position.

[0034] The connecting member 4 is used to connect the longitudinal mounting bracket 3 and the transverse mounting bracket 2, and has the characteristic of detachable connection. Such a design enables the arrangement of the laser welding head 6 to be adjusted and changed as needed.

[0035] The adjustment and installation mechanisms 5 are respectively fixed on both sides of the longitudinal installation bracket 3, and are used to install the laser welding head 6. The existence of the adjustment and installation mechanism 5 allows the position of the laser welding head 6 to be adjusted to meet specific welding requirements.

[0036] The design of the utility model aims to provide a flexibly adjustable laser welding head 6 fixing fixture, which is suitable for high-strength steel rolling equipment. Through the synergistic effect of the connecting plate 1, the transverse and longitudinal mounting brackets 3, the connecting piece 4 and the adjusting mounting mechanism 5, the device can effectively support and install the laser welding head 6, thereby improving production efficiency and adapting to different welding requirements.

[0037] refer to Figure 3 In this embodiment, the transverse mounting bracket 2 is composed of two long beams 201 and a first pressing plate 202 .

[0038] The long beam 201 is the main part of the transverse mounting bracket 2, and is parallel to the x direction, wherein the front ends and bottoms of the two long beams 201 are respectively fixedly connected to the connecting plate 1. Such connection ensures that the transverse mounting bracket 2 is firmly fixed.

[0039] The first pressing plate 202 is parallel to the y direction: the top of each long beam 201 is fixedly connected to the first pressing plate 202. The first pressing plate 202 is used to provide additional support and stability to ensure that the horizontal mounting bracket 2 can withstand various forces and pressures during operation.

[0040] Longitudinal mounting brackets 3: At least two longitudinal mounting brackets 3 are fixed to the outer side of the rear end of each long crossbeam 201. The function of these longitudinal mounting brackets 3 is to support the structure between the longitudinal mounting brackets 3 connecting the transverse mounting brackets 2 and the connecting member 4.

[0041] refer to Figure 2 and Figure 3 In this embodiment, two longitudinal mounting brackets 3 are provided, and each longitudinal mounting bracket 3 is composed of a short longitudinal beam 301 (parallel to the y direction), two middle vertical beams 302 (parallel to the z direction) and two second pressure plates 303 (parallel to the y direction).

[0042] Short longitudinal beams 301: Two short longitudinal beams 301 are disposed above the rear ends of the two long cross beams 201. The existence of these short longitudinal beams 301 helps to provide lateral support and connect the structure of the lateral mounting bracket 2 and the longitudinal mounting bracket 3.

[0043] Middle vertical beam 302: Each short longitudinal beam 301 is respectively fixed with a middle vertical beam 302 on both sides. The function of the middle vertical beam 302 is to enhance the stability of the overall structure and ensure that the installation position of the laser welding head 6 is firm and reliable.

[0044] Second pressing plate 303: The short longitudinal beam 301 and the middle vertical beam 302 are fixedly connected by the second pressing plate 303. The introduction of the second pressing plate 303 provides additional structural support and stability, making the entire longitudinal mounting bracket 3 more solid.

[0045] Connector 4: The short longitudinal beam 301 and the long transverse beam 201 are fixedly connected via a connector 4. The design of the connector 4 ensures a stable connection between the transverse mounting bracket 2 and the longitudinal mounting bracket 3 to support the installation of the laser welding head 6.

[0046] Through this structural design, the longitudinal mounting bracket 3 of the preferred embodiment forms a sturdy frame that can stably support and mount the laser welding head 6. This structure helps to ensure the precise position and firm installation of the welding head on the high-strength steel rolling equipment.

[0047] In this embodiment, the design of the connecting member 4 adopts an angle code 401 and a connecting bolt. The angle code 401 is provided with a circular hole for the bolt to pass through:

[0048] Connector 4: Angle code 401 is used. Angle code 401 is a connecting element with an angular structure, made of metal, and has the functions of fixing and connecting.

[0049] By using the angle code 401 as the connecting member 4, the following advantages are achieved:

[0050] Stability: The angle structure of the angle bracket 401 can provide stronger stability and support, ensuring that the connection between the horizontal mounting bracket 2 and the vertical mounting bracket 3 is firm and reliable.

[0051] Easy to install and disassemble: Angle code 401 usually has a simpler structure, making the assembly and disassembly process more convenient and efficient. This is very beneficial when the position of the laser welding head 6 needs to be frequently adjusted or changed during the production process.

[0052] In this embodiment, the long cross beam 201, the short longitudinal beam 301 and the middle vertical beam 302 are all made of aluminum profiles. The design of using aluminum profiles brings the following advantages:

[0053] Lightweight: The lightweight characteristics of aluminum profiles help reduce the weight of the overall device, making the equipment easier to carry, install and adjust.

[0054] High Strength: Despite being lightweight, aluminum profiles are still strong enough to meet the structural strength requirements of high-strength steel roll-forming equipment.

[0055] Corrosion resistance: The corrosion resistance of aluminum profiles makes the device more adaptable to humid or harsh working environments and prolongs its service life.

[0056] Thermal conductivity: The good thermal conductivity of aluminum profiles helps to dissipate heat during welding and prevent overheating.

[0057] In this embodiment, the design of the adjustment and installation mechanism 5 includes a horizontal adjustment mechanism and a vertical adjustment mechanism, and both mechanisms use a hand-cranked screw slide.

[0058] Transverse adjustment mechanism: A transverse hand-cranked screw slide 502 (parallel to the x direction) is used. The hand-cranked screw slide is a device that realizes linear motion by manually rotating a screw, and is suitable for adjusting the position of the laser welding head 6 transversely.

[0059] Vertical adjustment mechanism: A vertical hand-cranked screw slide 501 (parallel to the z direction) is used. The hand-cranked screw slide is also used for precise adjustment in the vertical direction to ensure that the height and angle of the laser welding head 6 meet the welding requirements.

[0060] The vertical adjustment mechanism is fixedly installed on the outer side of the middle vertical beam 302: such an installation method helps to maintain the stability of the overall structure, so that the vertical adjustment mechanism can flexibly adjust the position of the welding head when necessary.

[0061] The lateral adjustment mechanism is fixedly mounted on the vertical adjustment mechanism: this stacked design can effectively reduce the overall occupied space and simplify the structure of the adjustment mechanism.

[0062] By using the lateral and vertical adjustment mechanism of the hand-cranked screw slide, the following can be achieved:

[0063] Manual control: The operator can control the horizontal and vertical positions of the laser welding head 6 by manually rotating the lead screw to achieve more flexible adjustment.

[0064] Real-time adjustment: The hand-cranked screw slide provides real-time and precise adjustment, allowing the welding position of the welding head on different workpieces to quickly adapt to changes.

[0065] Cost-effectiveness: Compared with automated adjustment mechanisms, hand-cranked screw slides are usually more economical and affordable, reducing the cost of equipment manufacturing and maintenance.

[0066] refer to Figure 3 and Figure 4 A mounting plate 503 is fixedly mounted on the outer side of each transverse hand-cranked screw slide 502 by bolts, and the mounting plate 503 is used to be fixedly connected to the laser welding head 6.

[0067] Embodiment 2:

[0068] refer to Figure 5 The difference between the second embodiment and the first embodiment is only the short longitudinal beam 301 of the longitudinal mounting bracket 3. In the first embodiment, each longitudinal mounting bracket 3 has only one short longitudinal beam 301, while in the second embodiment, each longitudinal mounting bracket 3 has two short longitudinal beams 301. The gap between the two short longitudinal beams 301 corresponds exactly to the gap between the two long cross beams 201. A portion of space is left between the two short longitudinal beams 301, which is helpful for the welding operation. Welding usually requires sufficient space to ensure the accuracy and efficiency of the welding operation. By arranging two short longitudinal beams 301 on the longitudinal mounting bracket 3 and leaving a gap between them, a more flexible working space can be provided during the welding process, and the longitudinal mounting bracket 3 can be prevented from becoming an obstacle to welding.
