Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and particularly to a laser cutting device for steel structure production and processing. Background Technique

[0002] In the steel structure manufacturing and processing industry, laser cutting technology is widely used in steel plate blanking, edge finishing, and complex component contour cutting. Traditional laser cutting devices are mostly based on fixed work platforms or two-dimensional planar guide rail structures. Their typical structures include: fixed cutting platforms, moving crossbeams, Z-axis focusing systems, and laser cutting heads. Such devices generally use X-Y axis drive mechanisms to move the cutting head within a plane and cooperate with the focusing unit to complete the cutting process. This type of structure shows high precision and efficiency in planar cutting tasks and is suitable for batch standardized steel plate processing scenarios.

[0003] However, with the development of steel structure products towards large-scale, irregular, and spatially complex directions, existing fixed or two-dimensional guide rail laser cutting equipment has gradually exposed multiple technical limitations: Lack of spatial flexibility: Existing equipment generally relies on preset track or platform structures and is difficult to be freely arranged on large or irregular steel components (such as cylindrical columns, irregular beam segments). Especially at the component installation site, on-site cutting operations cannot be achieved.

[0004] Unable to fit different surface curvatures: For curved surface structures such as steel columns, bent plates, and structural joints, existing equipment generally adopts manual prefabricated templates or segmented processing methods, which not only reduces the degree of automation but also easily leads to seam errors and discontinuous cutting problems.

[0005] Limited attitude and trajectory: Due to the fact that most equipment is still limited to two-dimensional drive methods, when the laser cutting head faces non-regular edges or spatial intersection areas (such as weld ends, intersection nodes), it is difficult to achieve precise attitude control and dynamic path adjustment, resulting in cutting dead angles and unstable quality problems.

[0006] In view of this, research and improvement are carried out on the existing problems, and a laser cutting device for steel structure production and processing is provided to solve the current problems. The aim is to solve the problems and improve the practical value through this technology. Summary of the Invention

[0007] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0008] To this end, the technical solution adopted by the present invention is as follows: A laser cutting device for steel structure production and processing, comprising: a frame disc seat, a motor vehicle seat, a turntable assembly, an arc slide frame, and a laser cutting head slidably mounted on the surface of the arc slide frame. The frame disc seat is fixedly installed on the outer periphery of the motor vehicle seat. The turntable assembly includes an outer rotating ring, a toothed ring, and an outer rotor motor fixed on the surface of the motor vehicle seat. Bearing rings that are in sliding fit with the surface of the frame disc seat are provided on the upper and lower sides of the outer rotating ring. The toothed ring is fixed inside the outer rotating ring and is in meshing transmission with the output end of the outer rotor motor. A fixed ring sleeve is fixedly installed on the surface of the outer rotating ring. The two ends of the arc slide frame are rotatably sleeved inside the fixed ring sleeve;   The motor vehicle seat includes a fixed seat, a wheel frame, a magnetic attraction wheel, a shaft seat, and an airbag deformation assembly fixed on one side of the shaft seat. One end of the airbag deformation assembly is fixedly connected to the surface of the wheel frame. Upper guide rod groups and lower guide rod groups are provided on the surface of the shaft seat on the upper and lower sides of the airbag deformation assembly, and the other ends of the upper guide rod groups and the lower guide rod groups are movably connected to the surface of the wheel frame. The magnetic attraction wheel is rotatably installed on the surface of the wheel frame, and a driving motor for driving the magnetic attraction wheel to rotate is provided on the surface of the wheel frame. The number of the shaft seats and the wheel frames is two and they are symmetrically arranged. Meshing racks are provided on the surfaces of the two shaft seats; The airbag deformation assembly includes an air pump and an airbag body. The air pump is fixed on one side of the airbag body and is embedded inside the shaft seat. The air pump is arc-shaped, and several bone strips are provided on the surface of the airbag body.

[0009] In a preferred example of the present invention, it can be further configured that: A top cover is fixedly installed on the top surface of the fixed seat, and damping teeth for abutting against the meshing rack on the surface of the shaft seat are provided on the bottom surface of the top cover. The damping teeth are in the shape of flexible convex teeth.

[0010] Specifically, by engaging the damping teeth with the surface of the meshing rack, the rotational damping of the shaft seat is increased to achieve the morphological locking of the shaft seat.

[0011] In a preferred example of the present invention, it can be further configured that: Both the meshing rack and the upper guide rod group are double-link structures arranged in an X shape, and the connecting rods are flexible and bendable. The extending length of the meshing rack is greater than the extending length of the upper guide rod group.

[0012] Specifically, the meshing rack and the upper guide rod group are used to guide the expansion and elongation of the airbag deformation assembly and achieve a stable connection between the shaft seat and the wheel frame. The fact that the extending length of the meshing rack is greater than the extending length of the upper guide rod group can effectively maintain the arc-bending shape of the airbag deformation assembly.

[0013] In a preferred example of the present invention, it can be further configured that: The airbag body is a rubber cavity bag-like structure, and the bone strips are in a frame shape and are arranged in sequence along the length direction of the airbag body. The airbag body is in an arc shape in the filled state.

[0014] It forms a controllable arc-shaped variable structure through the cooperation of a rubber bladder-shaped airbag body and a frame-shaped bone strip, realizing uniform force and repeated reliability during the pressure-bearing deformation process of the airbag assembly. In a preferred embodiment of the present invention, it can be further configured that: a plurality of uniformly distributed magnetic strips are provided on the surface of the magnetic attraction wheel, each magnetic strip is obliquely arranged, and the magnetic pole directions between adjacent two magnetic strips are opposite.

[0015] Through the obliquely arranged magnetic strip structure with staggered magnetic poles, it improves the magnetic force coupling efficiency between the magnetic attraction wheel and the steel part, which helps to improve the stable adhesion of the moving part.

[0016] In a preferred embodiment of the present invention, it can be further configured that: the arc-shaped sliding frame is arc-shaped, both ends of the arc-shaped sliding frame are rotatably connected to the surface of the fixed ring sleeve, and there is rotational damping.

[0017] In a preferred embodiment of the present invention, it can be further configured that: an electromagnetic sliding rail assembly is provided on the surface of the arc-shaped sliding frame for driving the laser cutting head to slide on the surface of the arc-shaped sliding frame.

[0018] It realizes the precise sliding of the laser cutting head along the arc-shaped sliding frame through the electromagnetic sliding rail assembly, improving the moving response ability and processing efficiency of the laser head on a complex arc-shaped path.

[0019] In a preferred embodiment of the present invention, it can be further configured that: a fastener is provided on the top surface of the top cover and a power module is detachably installed. The power module is a lithium battery pack structure, and a control main board for a driving motor, an outer rotor motor and the arc-shaped sliding frame is built in the fixed seat.

[0020] By setting the detachable power module and the control main board, it realizes the independent power supply and centralized control functions of the device, improving the modular integration ability and use convenience of the device.

[0021] The beneficial effects obtained by the present invention are as follows: 1. In the present invention, through the setting of an independently controllable motor vehicle seat and an arc-shaped guide rail structure, and combined with the integrated layout of the vehicle frame disc seat and the turntable assembly, the independent walking and attitude control functions of the overall device on the steel structure surface are realized. A driving motor and a magnetic attraction wheel are integrated on the motor vehicle seat, enabling the device to achieve adsorption-type omnidirectional movement on the steel structure surface, suitable for various complex-shaped steel structure processing sites. This structure neither depends on an external guide rail system nor has good versatility and stability, thus significantly improving the autonomous operation ability of the laser cutting equipment in the scenario of special-shaped or large steel plates, and providing flexible support for cutting paths with different process requirements.

[0022] 2. In the present invention, a deformable unit with a flexible structure is introduced, including a deformation linkage structure composed of a rack, a guide rod group, and an airbag body, enabling the laser cutting module to achieve the conversion from a planar form to an arc-shaped or complex curved surface form through the deflection of the shaft seat and the ejection and expansion of the airbag deformation assembly. The above structure can not only automatically adapt to different structural morphologies such as steel plates and pipe columns, but also assist in restricting the bending posture of the airbag body through the bone strip to ensure that the device still has good bearing stiffness and precise control ability after deformation, solving the technical problem that existing cutting equipment is difficult to fit the surface of complex steel structures.

[0023] 3. In the present invention, a multi-dimensional motion coupling mechanism is constructed. The vehicle seat provides XY-plane positioning, the outer rotor motor in the turntable assembly drives the outer rotating ring to achieve rotational attitude adjustment, and at the same time, the arc slide can rotate within an arc range around its connecting shaft. This three-dimensional coordinated control structure enables the laser cutting head to achieve attitude switching and path adjustment in space, especially suitable for high-precision cutting operations in complex geometric areas such as arc-shaped welds, irregular contours, and corner strengthening parts. Compared with the traditional two-dimensional guide rail system, the present invention can significantly expand the cutting path coverage range and shape adaptability.

Detailed implementation mode

[0026] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in combination with the specific implementation modes and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0027] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0028] The following describes a laser cutting device for steel structure production and processing provided by some embodiments of the present invention with reference to the accompanying drawings. Embodiment 1:

[0029] Combined with Figures 1 - 8 As shown, a laser cutting device for steel structure production and processing provided by the present invention includes a frame turntable seat 100, a motor vehicle seat 200, a turntable assembly 300 and an arc slide 400. A laser cutting head 410 is slidably mounted on the surface of the arc slide 400.

[0030] The frame turntable seat 100 is fixedly installed on the outer periphery of the motor vehicle seat 200 for providing external structural support and linkage connection.

[0031] The turntable assembly 300 includes an outer rotating ring 310, a ring gear 320 and an outer rotor motor 330. The outer rotor motor 330 is fixed on the surface of the motor vehicle seat 200 for driving the rotation of the turntable assembly. Bearing rings 311 are provided on the upper and lower sides of the outer rotating ring 310. The bearing rings 311 are in sliding fit with the surface of the frame turntable seat 100 to achieve the stability of rotation. The ring gear 320 is fixed on the inner side of the outer rotating ring 310 and is in meshing transmission with the output end of the outer rotor motor 330 to achieve the transmission of driving force. A fixed ring sleeve 312 is also fixedly installed on the surface of the outer rotating ring 310. The two ends of the arc slide 400 are rotatably sleeved inside the fixed ring sleeve 312, so that the arc slide 400 can be adjusted in angle around the fixed ring sleeve 312.

[0032] The motor vehicle seat 200 includes a fixed seat 210, a wheel frame 220, a magnetic wheel 230, and a shaft seat 240. An airbag deformation assembly 250 is fixedly installed on one side of the shaft seat 240. One end of the airbag deformation assembly 250 is fixedly connected to the surface of the wheel frame 220. An upper guide rod group 242 and a lower guide rod group 243 are provided on the surface of the shaft seat 240, located above and below the airbag deformation assembly 250 respectively, and the other ends of the guide rod groups are movably connected to the surface of the wheel frame 220. The magnetic wheel 230 is rotatably installed on the surface of the wheel frame 220 and is driven to rotate by a driving motor 221 to realize the movement of the motor vehicle seat 200 on the surface of the steel structure. The two wheel frames 220 and the shaft seat 240 are symmetrically arranged, and meshing rack bars 241 are provided on the surfaces of the two shaft seats 240 respectively.

[0033] The airbag deformation assembly 250 includes an air pump 251 and an airbag body 252. The air pump 251 is fixed on one side of the airbag body 252 and is embedded and installed inside the shaft seat 240. The air pump 251 has an arc-shaped structure and is used to inflate the airbag body 252. The airbag body 252 is a rubber cavity bag-like structure and is arc-shaped in the inflated state. A number of rib strips 253 are provided on the surface. The rib strips 253 have a frame-shaped structure and are arranged in sequence along the length direction of the airbag body 252.

[0034] As Figure 3 and Figure 5 shown, a top cover 211 is fixedly installed on the top surface of the fixed seat 210, and damping teeth 212 are provided on the bottom surface of the top cover 211. The damping teeth 212 have a flexible convex tooth-like structure and are used to abut against the meshing rack bars 241 on the surface of the shaft seat 240. By the mutual engagement of the damping teeth 212 on the top cover 211 and the meshing rack bars 241 on the shaft seat 240, rotational damping of the shaft seat 240 is provided during the cutting process, thereby realizing the locking of its form and ensuring the stability of the device.

[0035] As Figures 7 - 9 shown, both the meshing rack bars 241 and the upper guide rod group 242 adopt a double-link structure arranged in an X shape. The link structure has flexible bendable properties, enabling the airbag deformation assembly 250 to expand and maintain a certain bending angle under the drive of the air pump 251. To achieve stable fitting of the device on different structural surfaces, in the design, the extension length of the meshing rack bars 241 is made greater than the extension length of the upper guide rod group 242, so as to effectively maintain the arc-shaped structure of the airbag body 252 during the airbag deformation process.

[0036] As Figure 4 shown, a plurality of magnetic strips 231 are provided on the surface of the magnetic wheel 230. The magnetic strips 231 are arranged obliquely, and the magnetic pole directions between adjacent two magnetic strips 231 are opposite. This arrangement enhances the magnetic adsorption force, enabling the device to firmly adhere to the surface of the steel structure for movement and operation.

[0037] The arc sliding carriage 400 is integrally in an arc structure, and its two ends are rotatably connected to the surface of the fixed ring sleeve 312, and a rotational damping mechanism is provided to adjust the angle and movement resistance of the sliding carriage, improving the control accuracy during the sliding of the laser head.

[0038] An electromagnetic slide rail assembly is provided on the surface of the arc sliding carriage 400, and this assembly can drive the laser cutting head 410 to perform a linear sliding motion along the surface of the arc sliding carriage 400, adapting to the cutting operation of an arc cutting path or a non-linear structure.

[0039] On the top surface of the top cover 211, there are fasteners for installing the power module. The power module adopts a lithium battery pack structure and has a detachable installation function, facilitating replacement and independent power supply. Inside the fixed seat 210, there are a driving motor 221, an outer rotor motor 330, and a control main board for controlling the movement of the arc sliding carriage 400, realizing the centralized control and power supply of the whole device.

[0040] Through the cooperation of the above structures and components, the present invention realizes the goals of the laser cutting device for autonomous movement, shape adaptation, and precise cutting on the surface of complex steel structures, and has remarkable advantages such as high structural integration, strong adaptability, and high control accuracy. Embodiment Two:

[0041] On the basis of the foregoing embodiment, this embodiment further optimizes the driving and control system of the motor vehicle seat 200, and replaces the original magnetic attraction wheels 230 with a Mecanum wheel structure to improve the omnidirectional movement performance of the device on the surface of a flat steel plate.

[0042] In this embodiment, the magnetic attraction wheels 230 are replaced by Mecanum wheels. The Mecanum wheels are evenly distributed at the four corners of the wheel frame 220, and can realize the movement of the device in any direction and rotation in place on the steel plate surface, improving the freedom degree of path planning and response accuracy. The Mecanum wheel consists of multiple rollers, and the axes of the rollers are arranged at a certain angle to the axis of the main wheel, suitable for various planar movements and steering.

[0043] At the same time, the control main board is arranged inside the fixed seat 210 to uniformly manage the control logic of multiple execution units. The control main board includes core units such as a microcontroller, a motor drive chip, a position detection module, and a communication interface. The microcontroller receives input signals from the user end or the sensing system, generates control instructions, and controls the rotation speed and direction of the Mecanum wheels respectively through the motor drive chip, thereby realizing the adjustment of the traveling path. The control system is also signal-connected to the outer rotor motor 330, the electromagnetic slide rail drive system, and the laser cutting head 410 to ensure the coordinated movement and linkage response between different components.

[0044] In addition, the control main board is preset with a path planning algorithm module, which can dynamically generate a moving trajectory according to the shape information of the cutting task and the current positioning data, and correct it in real time during the operation process to ensure the high-precision processing ability of the laser cutting head 410 on complex components.

[0045] Through the structural replacement and system optimization in the second embodiment, the device is further enhanced in terms of control sensitivity, path accuracy and working stability, and is applicable to more laser processing scenarios on the surfaces of complex steel structures and irregular graphics.

[0046] The working principle and usage process of the present invention are as follows: In the planar cutting mode: The wheel frame 220 and the fixed seat 210 are located in the same plane. The driving motors 221 on the surface of the wheel frame 220 synchronously drive the magnetic adsorption wheels 230 or Mecanum wheels to rotate, so as to realize the walking movement of the entire laser cutting device. The driving motors 221 on both sides of the fixed seat 210 respectively drive the magnetic adsorption wheels 230 or Mecanum wheels on the left and right sides to rotate at different speeds or in different directions asynchronously, and complex maneuvering walking functions such as turning and turning in place of the entire device can be realized.

[0047] Under the driving action of the outer rotor motor 330, the toothed ring 320 and the outer rotating ring 310 can rotate around the outer periphery of the motor vehicle seat 200 under the support of the vehicle frame disc seat 100 and the bearing ring 311, so as to drive the arc slide frame 400 and the laser cutting head 410 above it to rotate around the motor vehicle seat 200, meeting the trajectory control requirements of complex cutting lines.

[0048] Furthermore, before the cutting starts, the rotational connection relationship between the arc slide frame 400 and the two end fixed ring sleeves 312 can be manually adjusted to make the arc slide frame 400 and the laser cutting head 410 generate a preset inclination angle configuration, so as to realize the diagonal cutting operation.

[0049] In the cutting mode on the surface of a columnar steel structure: As Figure 9 shown, the shaft seat 240 can be manually deflected first, and the two shaft seats 240 are controlled to deflect relatively synchronously. Then, the air pump 251 starts to work, inflating the airbag body 252, causing the airbag body 252 to expand and deform. Under the cooperation and guidance of the upper guide rod group 242 and the lower guide rod group 243, the wheel frame 220 synchronously elongates along the arc direction of the airbag body 252, thus completing the switching of the entire form from the planar form to the arc-shaped adaptation structure.

[0050] In this form, the magnetic strip 231 on the surface of the magnetic attraction wheel 230 is utilized to enhance the adhesion between the magnetic attraction wheel 230 and the surface of the steel structure column, or the omnidirectional movement ability of the Mecanum wheel is used to enhance the attachment and driving stability of the wheel frame 220 on the curved steel structure. Driven by the driving motor 221, the device can continuously crawl along the surface of the columnar steel structure. The laser cutting head 410 slides along the cutting trajectory under the guidance of the surface of the arc sliding frame 400, thereby achieving the operation purpose of continuously circularly cutting the surface of the steel structure.

[0051] In summary, the laser cutting device of the present invention has the ability to adapt to multiple scenarios. Through combined control methods such as structural deformation, rotation control, and path planning, it can achieve efficient and precise cutting operations on various forms such as the plane or column surface of the steel structure.
