Description

Technical Field

[0001] The invention belongs to the technical field of H-beam welding equipment, and in particular relates to energy-saving assembled building H-beam automatic welding equipment. Background Art

[0002] With the rapid development of the modern construction industry, prefabricated buildings are favored for their high efficiency, environmental protection and energy saving. As a key component of prefabricated buildings, the welding quality and efficiency of H-beams are directly related to the stability and safety of the entire building structure. However, the traditional H-beam welding process has many shortcomings, such as low welding accuracy, poor stability, low efficiency, high energy consumption and serious environmental pollution. These problems have seriously restricted the further development of the prefabricated building industry.

[0003] First, it is often difficult to ensure high-precision welding results when welding H-beams using traditional welding processes. Due to the complex cross-sectional shape of H-beams and the different welding requirements at different angles and positions, traditional manual welding or simple mechanized welding methods are difficult to meet the requirements of high-precision and high-quality welding.

[0053] A laser welding gun 18 is disposed on the bottom side of the assembly seat 16 , and an adaptive focusing lens group 19 is disposed on the bottom side of the receiving plate 14 .

[0054] It should be noted that, since the existing H-beam welding process has the problems of low welding accuracy, poor stability, low efficiency, high energy consumption and serious environmental pollution, this solution achieves high-precision, high-stability and efficient automated operation in the H-beam welding process, and significantly improves the welding quality; specifically, the combination of multiple laser welding guns 18 and the rotatable welding table 6, as well as the damping adjustable shock-absorbing spring 10 and the high-temperature resistant ceramic liner 11 on the outside of the clamping plate 9, ensure the stability and accuracy of the welding process, so that the equipment can flexibly respond to welding requirements at different angles and positions; at the same time, the equipment can automatically adjust the laser focus according to the actual situation of the welding part, and match The real-time image capture of the CCD industrial camera 20 and the visual feedback of the touch control screen 17 realize the intelligent control of the welding process, improve the welding efficiency and reduce the human error; in addition, the application of the cold water spray head 5 and the infrared temperature sensor 21 effectively suppresses the high temperature and ensures the safety and stability of the welding process, while the adsorption hood 22 and the filter box 24 purify the air in the welding area and protect the health of the operator; most importantly, the detachable connection design between the welding frame 4 and the base 1 is not only convenient for daily maintenance and future upgrades, but also effectively avoids the influence of welding vibration on the stability of the equipment, providing a strong guarantee for the long-term stable operation of the equipment.

[0055] Specifically, in this embodiment, the scheme mainly includes a machine base 1, and a welding frame 4 is detachably connected to the machine base 1 through embedded fasteners. This design is not only convenient for daily maintenance and future upgrades of the equipment, but also avoids the vibration that may be generated by the welding process when the welding table 6 is directly placed on the operating platform 2, thereby improving the stability of the entire equipment;

[0056] When preparing for welding, the H-beam to be welded is accurately placed on the rotatable welding table 6; the design of the rotatable welding table 6 enables the equipment to easily cope with the welding requirements of H-beams at different angles and positions, greatly improving the flexibility and applicability of the equipment;

[0057] Then, the piston rod of the electric telescopic rod 8 starts to telescope, driving the clamping plate 9 to clamp and fix the H-shaped steel; the damping adjustable shock absorbing spring 10 and the high temperature resistant ceramic liner 11 connected to the outside of the clamping plate 9 can effectively reduce the impact of vibration and heat on the H-shaped steel during welding, ensuring the welding quality while also improving the clamping effect of the clamping plate 9 on the uneven clamping surface;

[0058] When welding is ready, the piston rod of the hydraulic cylinder 12 begins to extend and retract, driving the screw slide 13 to adjust the height; the moving end of the screw slide 13 is responsible for driving the receiving frame and the extended side plate 15, the assembly seat 16 and the laser welding gun 18 thereon to move precisely in the horizontal direction to ensure that the laser welding gun 18 can accurately align with the part to be welded;

[0059] During the welding process, a torque sensor (HBM T40B) is arranged between the assembly seat 16 at the bottom side of each extension side plate 15 and the extension side plate 15 to monitor the effect of torque changes during the welding process in real time; through this monitoring, the operator can adjust the welding parameters in time to ensure the stability and reliability of the welding quality;

[0060] In addition, the equipment is equipped with three laser welding guns 18, which can detect gaps and quickly weld different surfaces of H-shaped steel; the adaptive focusing lens group 19 equipped with the laser welding gun 18 can automatically adjust the laser focus according to the actual situation of the welding part, thereby achieving high-quality welding effects.

[0061] In a further preferred embodiment of the present invention, Figure 7 As shown, the shock absorbing spring 10 has an integrated digital damper, and the damping coefficient can be adjusted within a range of 5N-50N·s / m; a temperature sensor is embedded inside the clamping plate 9, and the surface of the liner 11 is laser-engraved with anti-slip patterns.

[0062] In this embodiment, the temperature sensor (PT100) embedded in the inner side of the clamping plate 9 monitors the temperature changes of the clamping area and the H-beam in real time to ensure proper temperature control during welding and avoid damage to the material caused by overheating;

[0063] The damping spring 10 on the outside of the clamping plate 9 has a digital damper integrated inside, so that the damping coefficient can be accurately adjusted within a wide range of 5N-50N·s / m; according to the specific needs of the welding operation and the material characteristics of the H-beam, the operator can adjust the damping coefficient through the control system to effectively reduce the vibration generated during the welding process and improve the welding stability and accuracy;

[0064] At the same time, the surface of the pad 11 is laser engraved to form anti-slip patterns; this design not only enhances the friction between the clamping plate 9 and the H-shaped steel to prevent slippage due to vibration or external force during welding, but also further improves the tightness and stability of the clamping, ensuring the safety of the welding operation.

[0065] In a further preferred embodiment of the present invention, Figure 5As shown, a CCD industrial camera 20 and a cold water spray head 5 are arranged on the bottom side of the receiving plate 14, and an infrared temperature sensor 21 (FLIR T1020) is arranged outside the cold water spray head 5. The cold water spray head 5 and the infrared temperature sensor 21 are arranged orthogonally at 90°.

[0066] In this embodiment, the CCD industrial camera 20 captures the image information of the welding area in real time and transmits these high-definition images to the touch control screen 17. The touch control screen 17 analyzes the received images and can accurately identify the welding position and the specific form of the weld, and can even detect potential welding defects in advance. This function provides intuitive and detailed visual feedback to operators, allowing them to respond quickly, adjust welding parameters or take corresponding measures, thereby ensuring the accuracy of the welding operation and the quality of the final product.

[0067] During welding, the cold water spray head 5 is connected to an external water source; the cold water spray head 5 sprays cooling water evenly on the welding part and its surrounding area, effectively suppressing the high temperature generated during welding, significantly reducing the temperature gradient of the heat-affected zone, not only extending the service life of welding equipment and key components, but also significantly improving welding quality and operation efficiency;

[0068] In addition, the infrared temperature sensor 21 can monitor the temperature changes in the welding area in real time and non-contactly, ensuring that the temperature during the welding process is always within a safe and controllable range, thereby further ensuring the safety and stability of the welding operation.

[0069] In a further preferred embodiment of the present invention, Figure 7 As shown, an adsorption cover 22 is arranged on one side of the welding frame 4 facing the welding platform 6. The adsorption cover 22 is covered with a three-layer composite filter screen 23, wherein the outer layer is a 304 stainless steel perforated screen, the middle layer is a nanofiber membrane, and the inner layer is an activated carbon fiber felt.

[0070] In this embodiment, the adsorption hood 22 is used to capture and filter the smoke and harmful gases generated during the welding process. The outer filter screen is made of 304 stainless steel perforated screen, which is durable and corrosion-resistant to resist the impact of smoke and splashes, reducing the burden on the subsequent filter layer.

[0071] The middle layer uses a nanofiber membrane, which can efficiently capture tiny particles in the air, including ultra-fine smoke and harmful aerosols generated during welding, further improving the filtration effect;

[0072] The inner layer is activated carbon fiber felt, which can not only absorb the remaining small particles of smoke, but also effectively remove harmful gases generated during the welding process, such as ozone, nitrogen oxides, etc., thereby purifying the air in the welding area and protecting the health of operators.

[0073] In a further preferred embodiment of the present invention, Figure 7 As shown, a sealed filter box 24 is provided on the side wall of the operating platform 2, and the filter box 24 is filled with filter liquid. A high temperature resistant porous adsorption material floats on the surface of the filter liquid. The adsorption cover 22 is connected to the filter box 24 through an anti-corrosion conduit 25. The conduit 25 extends to 1 / 3 of the height of the inner cavity of the filter box 24, and an umbrella-shaped guide cap 26 is provided at the end of the conduit 25.

[0074] In this embodiment, during the welding operation, the captured smoke and gas are then transported to the filter box 24 through the conduit 25; the conduit 25 extends to 1 / 3 of the height of the inner cavity of the filter box 24. This design not only ensures that the smoke and gas can fully contact with the filtered liquid, but also effectively avoids the problem of blockage that may be caused by the end of the conduit 25 being too close to the liquid surface; the umbrella-shaped guide cap 26 at the end of the conduit 25 not only increases the contact area between the smoke and gas and the filtered liquid, but also enables the smoke and gas to be more evenly distributed in the filtered liquid, thereby significantly improving the filtering efficiency;

[0075] The high temperature resistant porous adsorption material floating on the surface of the filtered liquid can further improve the removal efficiency of smoke and harmful gases, ensuring that the adsorption material can maintain its stability and effectiveness even in high temperature welding environment;

[0076] As the welding operation continues, smoke and gas are continuously captured by the adsorption hood 22 and transported to the filter box 24 through the conduit 25; in the filter box 24, they are in full contact with the filter liquid and the high temperature resistant porous adsorption material, and the harmful substances are effectively captured and neutralized, thereby ensuring the cleanliness and safety of the welding operation environment.

[0077] In a further preferred embodiment of the present invention, Figure 2 As shown, a gas outlet 27 is arranged on the top of the filter box 24, and a filter sleeve 29 is threadedly fitted at the gas outlet 27. An activated carbon filter element is filled in the filter sleeve 29, and the activated carbon filter layer includes a composite of honeycomb activated carbon and a ceramic fiber support mesh.

[0078] In this embodiment, the gas after water washing and filtration continues to rise and eventually reaches the gas outlet 27 at the top of the filter box 24. In order to ensure the cleanliness of the exhaust gas, a threaded filter sleeve 29 is provided at the gas outlet 27. This design is not only convenient for replacement and maintenance, but also ensures a tight connection between the filter sleeve 29 and the gas outlet 27 to prevent gas leakage. The filter sleeve 29 is filled with an activated carbon filter element. The honeycomb activated carbon can further remove tiny particles, harmful gases and odors in the gas, while the ceramic fiber support mesh enhances the structural strength of the activated carbon filter element and prevents the falling of activated carbon particles. At the same time, it ensures the smooth flow of the gas, deeply purifies the gas, and ensures that the final exhausted gas fully meets environmental protection standards.

[0080] In this embodiment, during the welding operation, the lead screw slide 13 is driven by the motor to perform precise vertical movement along the guide rail 30. This movement not only realizes the accurate positioning of the welding gun head on the H-shaped steel, but also enables the welding process to be automated according to a preset procedure. The close cooperation between the guide rail 30 and the lead screw slide 13 ensures the continuity and stability of the welding operation and improves the welding quality and efficiency.
