Description

Technical Field

[0001] This utility model relates to the field of steel component processing technology, and in particular to a high-precision laser cutting device for steel components. Background Technology

[0002] With the acceleration of industrialization and urbanization, steel structures are being used more and more widely in fields such as construction, bridges, shipbuilding, and machinery manufacturing. The processing accuracy and production efficiency of steel components directly affect the project quality and construction progress, thus placing higher demands on the cutting technology of steel components.

[0003] A search revealed Chinese Patent Publication No. CN221473859U, which discloses a laser cutting device for steel components, specifically relating to the field of laser cutting technology. The device includes a worktable, a connecting plate fixedly mounted on one lower surface of the worktable, a fixing component fixedly mounted on one side of the connecting plate, an arc-shaped groove on one side wall of the fixing component, and multiple evenly distributed locking blocks fixedly mounted on one side of the fixing component. A gear is mounted on one side of each locking block, meshing with the locking block. A rotating rod is fixedly inserted into the gear, with one end of the rotating rod slidably positioned in the arc-shaped groove. This invention, by incorporating the arc-shaped groove, locking blocks, gear, rotating rod, lifting block, reciprocating component, suction frame, air inlet pipe, filter box, air outlet pipe, and fan, achieves the effect of cleaning up the smoke generated during laser cutting of steel components. In use, the reciprocating component drives the suction frame to move back and forth, absorbing the generated smoke and preventing it from being inhaled by workers.

[0004] The aforementioned patent specification mentions that "the top of the workbench 1 is provided with symmetrically distributed grooves 4, and a double-ended screw 41 is rotatably disposed in the grooves 4. Symmetrically distributed threaded blocks 42 are fitted onto the external threads of the double-ended screw 41. The threaded blocks 42 are slidably disposed in the grooves 4, and a clamping plate 43 is fixedly disposed at the top of the threaded blocks 42. One end of the double-ended screw 41 rotatably passes through one side wall of the workbench 1 and is placed on the outside. A synchronous pulley 410 is fixedly fitted onto the outside of the double-ended screw 41, and a belt 420 is used for transmission between the synchronous pulleys 410. A second motor 430 is provided at one end of one of the double-ended screws 41, and one of the double-ended screws 41 is coaxially fixedly installed with the driving end of the second motor 430. Before cutting the steel component, the steel component is placed on the workbench 1, and then the second motor 430 is started." Motor 430 drives one of the double-ended screws 41 to rotate. One of the double-ended screws 41 drives the other double-ended screw 41 to rotate via synchronous pulley 410 and belt 420. During the rotation of the double-ended screws 41, the threaded block 42 is driven to move in opposite directions. The threaded block 42 drives the clamping plate 43 to move in opposite directions. When the clamping plate 43 is tightly attached to the steel component, the second motor 430 is turned off. By setting up the double-ended screws 41, threaded block 42, and clamping plate 43, the steel component can be clamped and fixed, preventing the steel component from shaking during cutting and improving the cutting accuracy of the steel component. However, the mobile cutting scheme based on the robot is affected by poor running stability, which can easily lead to the risk of dimensional deviation. Utility Model Content

[0005] This invention proposes a high-precision laser cutting device for steel components, which aims to improve the problems of low adaptability of some existing devices to complex-shaped components and the easy occurrence of errors caused by equipment vibration or other external interference factors.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A high-precision steel component laser cutting device includes a main frame mechanism. A dual-axis servo drive mechanism is slidably connected to the top of the main frame mechanism. A three-dimensional dynamic lens mechanism is fixedly connected to the four corners of the top of the main frame mechanism. Horizontal moving mechanisms are fixedly connected to both outer sides of the main frame mechanism. A three-dimensional control mechanism is fixedly connected to the top of the horizontal moving mechanisms. A steel clamping mechanism is fixedly connected to one side of the three-dimensional control mechanism. The dual-axis servo drive mechanism includes two x-axis guide rails. The bottom of the two x-axis linear guide rails is fixedly connected to the top of the main frame mechanism. X-axis guide rail sliders are slidably connected to the top of the two x-axis linear guide rails. A laser cutting frame is fixedly connected to the top of the x-axis guide rail sliders. A y-axis slider is slidably connected to the top of the laser cutting frame. A z-axis slider is slidably connected to the outer front side of the y-axis slider. A laser cutting head is fixedly connected to the bottom of the z-axis slider.

[0008] The above solution ensures a highly efficient and precise cutting process. The design of the three-dimensional dynamic lens mechanism and laser cutting head enables precise cutting of steel components, meeting the demands of high-precision processing. The dual-axis servo drive mechanism, along with the X, Y, and Z axis sliders, allows the laser cutting machine to move flexibly in three-dimensional space, adapting to steel components of different shapes and sizes. The robust design of the main frame mechanism and its fixed horizontal movement mechanism ensure stability during the cutting process, reducing cutting errors caused by vibration or displacement. The combination of the horizontal movement mechanism and the three-dimensional control mechanism enables the steel clamping mechanism to quickly and accurately position and clamp the workpiece, improving overall work efficiency.

[0009] As a further description of the above technical solution:

[0010] The main frame mechanism includes a base frame, a central main shaft is fixedly connected to the middle of the base frame, and side auxiliary shafts are fixedly connected to both sides of the top of the base frame. Multiple waste discharge ports are provided in the middle of the base frame.

[0011] Through the above design, the main frame mechanism ensures the stable fixation of the central spindle through the base frame design, while the auxiliary side shafts on both sides of the top enhance the overall structural support and stability. Furthermore, the multiple waste discharge ports in the middle of the base frame effectively improve waste handling efficiency.

[0012] As a further description of the above technical solution:

[0013] The three-dimensional dynamic camera mechanism includes four gantry support frames. The bottom of the gantry support frames is fixedly connected to the top of the main frame mechanism. A transverse guide rail is fixedly connected to the adjacent side of two gantry support frames in the same row. A slider is slidably connected to the outside of the transverse guide rail. A longitudinal guide rail is fixedly connected to the adjacent side of two sliders.

[0014] The above-described scheme, through the robust design of the four gantry support frames, effectively secures them to the top of the main frame mechanism, ensuring the overall structural stability. The transverse guide rails between adjacent gantry support frames, in conjunction with the externally slidable slider one, provide flexible lateral movement capabilities. Simultaneously, the longitudinal guide rails fixedly connected to the adjacent side of slider one further enhance the mechanism's multi-dimensional motion capabilities.

[0015] As a further description of the above technical solution:

[0016] A second slider is slidably connected to the outside of the longitudinal guide rail. An electric push rod is fixedly connected to the bottom of the second slider, and a dynamic observation lens is fixedly connected to the bottom of the electric push rod.

[0017] The above scheme enables flexible movement of the dynamic observation lens by sliding the second slider on the longitudinal guide rail. The electric push rod fixedly connected to the bottom of the second slider can precisely control the longitudinal movement of the observation lens, improving the adjustment efficiency and ease of operation of the lens.

[0018] As a further description of the above technical solution:

[0019] The horizontal moving mechanism includes a main frame side guide rail, the outer side of which is fixedly connected to the outside of the base frame. A slider three is slidably connected to the outside of the main frame side guide rail, and a support plate is fixedly connected to the outside of the slider three.

[0020] The above solution, through the design of the side guide rails on the main frame, achieves a stable connection with the base frame, ensuring the stability and reliability of the overall structure. The sliding connection of slider three on the side guide rails of the main frame allows the support plate to move flexibly, thereby improving the system's operational flexibility and adaptability.

[0021] As a further description of the above technical solution:

[0022] The three-dimensional control mechanism includes a fixed base, the bottom of which is fixedly connected to the top of the support plate. A dual-head motor is fixedly connected to the top of the fixed base. A rotating arm is fixedly connected to the drive end of the dual-head motor. The tops of the two rotating arms are limited and fixed by a connecting shaft. A drive motor is fixedly connected to the outer side of one of the rotating arms. A rotating forearm is fixedly connected to the drive end of the drive motor.

[0023] The above solution provides a solid foundation through the stable connection between the fixed base and the support plate, ensuring the stability of the entire system. The dual-head motors installed at the top drive the rotating arms, enabling flexible control in multiple directions. The two rotating arms are fixed by a connecting shaft, enhancing the reliability and safety of the structure. In addition, the connection between the drive motor and the rotating arm allows the system to perform precise operations within a smaller range.

[0024] As a further description of the above technical solution:

[0025] The steel clamping mechanism includes a connecting base, which is externally fixedly connected to the inside of the rotating arm. A second drive motor is fixedly connected to the bottom of the connecting base, and a connecting rod is fixedly connected to the drive end of the second drive motor.

[0026] By using the above solution, the stability and reliability of the clamping device are ensured by firmly fixing the connecting base inside the rotating arm. The drive motor at the bottom provides power to the system, and the connecting rod connected to the drive end enables flexible control of the clamping action. This design not only improves the operating accuracy and efficiency of the clamping mechanism, but also enhances its adaptability to different working environments, ensuring the safety and stability of steel during processing and transportation.

[0027] As a further description of the above technical solution:

[0028] Two clamping blocks are slidably connected to the outer side of the connecting base. Two arc-shaped plates are provided between the connecting rod and the two clamping blocks. One end of the arc-shaped plate is rotatably connected to the outside of the connecting rod, and the other end of the arc-shaped plate is rotatably connected to the outside of the clamping block. An installation hole is provided in the middle of the clamping block.

[0029] The above scheme, by setting two arc-shaped plates, forms a flexible clamping mechanism. One end of the arc-shaped plate is rotatably connected to the connecting rod, and the other end is rotatably connected to the clamping block, allowing the clamping block to achieve a greater range of motion and higher flexibility during clamping. In addition, the mounting hole design in the middle of the clamping block facilitates the clamping of workpieces of different shapes and sizes.

The main frame, as the basic load-bearing unit, is made of high-strength aluminum alloy frame welded together. It has an overall rectangular frame design and internal reinforcing ribs to improve rigidity. This improves the single and rigid function of traditional fixed laser cutting equipment and realizes multi-functional integrated operation. Attached Figure Description
