With the continuous advancement of science and technology and the growing demand for industrial production, steel plate straight seam welding machine technology has also developed significantly.

[0003] There are many shortcomings in the existing straight seam welding machine technology for steel plate processing. First, during the welding process of the traditional welding machine, when the steel plate is subjected to the vibration effect applied during the existing vibration welding, the vibration force will be transmitted along with the steel plate, and the welded part of the steel plate will also be affected by the vibration when the welding head welds the new part, resulting in uneven stress distribution and increasing the risk of weld cracking. Secondly, the traditional welding machine cannot apply appropriate vibration force to the steel plate during the welding process. The vibration effect is always applied to the steel plate by transmission, which will prevent the welding points far away from the application position from receiving a good welding effect, and it is impossible to make any welding position receive the same vibration effect.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. In this scheme, by providing a pressing assembly, the gap between the two fixed pressure plates is used as a welding opening to ensure that the laser welding head can accurately align with the weld position, and the connecting plate, insert sheath and limiting plate body above the fixed pressure plate cooperate with the side plug-in block of the laser welding head to achieve a tight connection between the welding assembly and the pressing assembly. During the welding process, the four weighting blocks apply additional weight to the welding area of ​​the steel plate, effectively preventing the steel plate from being deformed or moved due to welding heat or external force. At the same time, the setting of the buffer layer can absorb the excess vibration generated during the welding process, ensuring that the vibration effect is concentrated on the welding position, avoiding negative effects on other welded parts of the steel plate, improving the stability of welding, and making the vibration effect more concentrated on the current welding position, avoiding the destruction of the microstructure of the weld due to the conducted vibration of the welded part, and reducing the generation of negative effects such as cracks; 2. In this scheme, by providing a vibration component, a small motor drives a small threaded rod to cooperate with the meshing block of the sliding convex strip, so as to realize the precise movement of the sliding convex strip on the bottom surface of the lifting plate body. This movement mode is synchronized with the movement of the welding assembly, ensuring that the vibration source is always located below the welding position, providing a continuous and uniform vibration effect for the weld. The vibration effect not only promotes convection and disturbance of the liquid in the molten pool, but also helps the floating and escape of gas and impurities, and reduces the pores and slag inclusions inside the weld; at the same time, it can also promote the plastic deformation of the weld metal at high temperature, adjust the distribution of residual stress, reduce the stress concentration, and significantly improve the crack resistance of the weld; 3. In the present scheme, a preheating component is provided. When the supporting component rises, if the trigger button is not triggered, the data processor determines that the steel plate is too thick, and then starts the preheating component. The exhaust fan inside the heating tube draws in external air, and forms hot air after being heated by the electric heater. The hot air is blown to the surface of the steel plate through the connecting air duct and the air outlet duct, so as to achieve uniform preheating of the steel plate. The preheating treatment not only increases the temperature of the steel plate, making it easier to form a molten pool during welding, but also reduces the generation of welding stress and cracks. After welding, the control motor drives the meshing gear cylinder to cooperate with the meshing tooth groove, so that the air outlet duct and the connecting air duct rotate downward, and the exhaust fan draws in air again and blows air to cool the finished steel plate after welding through the air outlet duct, gradually reducing the temperature of the steel plate, and avoiding thermal stress or deformation problems caused by rapid cooling.

When the drive motor 6 is started, the meshing threaded rod 7 rotates accordingly, and the meshing effect of the meshing threaded rod 7 and the meshing plate 29 enables the data processor 30 to move with the fixed plate body 25 above the fixed top pipe 5, and stop after reaching one end of the fixed top pipe 5. Subsequently, the push motor 26 is driven according to the signal to push the sliding frame 28 to one side. Subsequently, the laser welding head 31 is lowered by the action of the hydraulic rod arranged above it, and is connected to the pressing assembly by the side plug block 32 on its side. At this time, the preparation process is completed. Subsequently, the staff can use the laser welding head 31 to perform the welding process on the steel plate original, and the drive motor 6 immediately rotates in the opposite direction, driving the laser welding head 31 to move on the surface of the steel plate and complete the welding work. The auxiliary mechanism is started synchronously during the welding work, and has the effect of improving the welding effect.

[0018] An auxiliary mechanism is provided at the center of the top frame 2, and the auxiliary mechanism includes a bearing component and a pressing component, and the pressing component includes two fixed pressure plates 3, and the two fixed pressure plates 3 are fixedly connected to the adjacent groove side walls, and the gap between the two fixed pressure plates 3 is a welding opening, and the upper surfaces of the two fixed pressure plates 3 are slidably connected with a weighting component, and the weighting component includes a connecting plate 17, and the bottom surface of the connecting plate 17 is provided with a bottom bracket 18, and the bottom surface of the bottom bracket 18 is provided with four weighting blocks 19, and the bottom surface of the weighting block 19 is provided with a buffer layer 20, and the bottom surface of the buffer layer 20 is provided with a heat insulation plate 21, and the heat insulation plate 21 is fitted with the upper surfaces of the two fixed pressure plates 3, and the upper surface of the connecting plate 17 is provided with a plug sheath 16, and the upper surface of the plug sheath 16 is provided with a limiting plate body 9, and one side surface of the sliding frame body 28 is provided with a side plug block 32 that matches the plug sheath 16; The pressing assembly is used to provide an additional fixing effect on the surface of the steel plate during welding. In the preparation stage of welding, the side insert block 32 comes into contact with the limiting plate 9 during the movement of the welding assembly and then stops. Subsequently, when the laser welding head 31 descends, the side insert block 32 on its side surface will be inserted into the insert sleeve 16 from above. At this time, the laser welding head 31 is located at the center of the four weighting blocks 19. When the welding work starts, the welding assembly is moving, and the pressing assembly, through the combination of the insert sleeve 16 and the side insert block 32, will drive the bottom bracket 18 to move along with the welding assembly. The laser welding head 31 is always located at the center of the four weight blocks 19 for welding. During the welding process, the four weight blocks 19 will apply additional weight to the welding position area of ​​the steel plate, and absorb the excess vibration through the buffer layer 20, so that the vibration effect generated by the vibrating component is more concentrated on the current welding position, and will not be transmitted to other parts of the steel plate, so as to avoid the damage of the microstructure of the weld due to the excessively strong conducted vibration in the welded part, resulting in the reduction of weld strength and the generation of cracks and other negative effects.

[0019] The bearing assembly includes a plate body component and a vibration component, and the plate body component includes: a bottom fixed column 11, the bottom fixed column 11 is fixedly installed on the upper surface of the bottom frame 1, the upper surface of the bottom fixed column 11 is provided with an electric telescopic rod 33, and the end of the output shaft of the electric telescopic rod 33 is provided with a lifting plate body 13, a side surface of the top frame 2 is provided with a limiting block 34 for limiting the lifting plate body 13, a side surface of the lifting plate body 13 is provided with a lifting plate body 12, and a side surface of the lifting plate body 12 is provided with a side slider 37, the inner side surface of the bottom frame 1 is provided with a slideway matched with the side slider 37, and a bearing plate body 36 is provided at the center of the lifting plate body 12; The plate body component is used to place the steel plate original before the welding work starts. Before the welding work starts, the staff places the steel plate original on the top of the bearing plate 36. Then, when the welding work is carried out, the electric telescopic rod 33 is driven to start by the staff signal, and the lifting plate 13 is driven to rise, and the lifting plate 12 is driven to rise synchronously. The side slider 37 on the side surface of the lifting plate 12 slides inside the slide. As the lifting plate 13 rises, the lifting plate 12 is finally fitted with the bottom surface of the top frame 2, and then the welding work can be carried out. If the lifting plate 12 fails to fit successfully with the bottom surface of the top frame 2, it can be judged that the steel plate is too thick. The preheating component is immediately started to preheat the steel plate original. After the preheating work is completed, the welding work can be completed normally.

[0020] The vibration component includes: a sliding convex strip 35, the sliding convex strip 35 is located below the bearing plate body 36, the bottom surface of the bearing plate body 36 is provided with a bottom convex block 45 matched with the sliding convex strip 35, and the two side surfaces of the bottom convex block 45 are provided with a force-bearing side plate 43, the inner side surface of the lifting plate body 12 is provided with a plate body side groove 46 matched with the force-bearing side plate 43, and a force spring 44 is provided between the inner upper and lower surfaces of the plate body side groove 46 and the surface of the force-bearing side plate 43, and a hidden groove is provided on one side surface of the lifting plate body 13, and the hidden groove A small motor 39 is arranged inside, a small threaded rod 42 is arranged on the output end of the small motor 39, an engaging block 38 matching with the small threaded rod 42 is arranged on the bottom surface of the sliding protrusion 35, sliding side frames 41 are arranged on both sides of the sliding protrusion 35, sliding grooves 47 matching with the sliding side frames 41 are opened on both sides of the bottom surface of the lifting plate body 12, a positioning light 40 is also arranged on the bottom surface of the sliding protrusion 35, and a light detection head 23 matching with the positioning light 40 is also arranged on the bottom side surface of the lower support rod 22; During the welding process, the vibrating component applies a certain vibration force to the steel plate original. The vibration can promote convection and disturbance of the liquid in the molten pool, making it easier for gas and impurities to float to the surface of the molten pool and then escape or be removed, thereby reducing the pores and slag inclusions inside the weld. It can also promote the plastic deformation of the weld metal at high temperature, thereby adjusting the distribution of residual stress, reducing the stress concentration, and improving the crack resistance of the weld. Before the welding work begins, when the welding assembly reaches one side of the fixed top pipe 5 and completes the connection with the pressing assembly, the telescopic motor 24 at one end of the connecting rod 4 is started according to the signal of the staff, and drives the lower support rod 22 to descend. When the light detection head 23 at the end of the lower support rod 22 is parallel to the positioning light 40, the laser emitted by the positioning light 40 will be received by the light detection head 23, and the lower support rod 22 will stop driving and transmit the signal to the data processor 30. Subsequently, the small motor 39 receives the drive signal sent by the data processor 30. The signal is driven, and the meshing effect of the small threaded rod 42 and the meshing block 38 is used to make the sliding protrusion 35 move on the bottom surface of the lifting plate body 12. During the movement, the positioning light 40 and the light detection head 23 always maintain the sensing state, so as to ensure that the moving speed of the sliding protrusion 35 is the same as that of the welding assembly. The sliding side frame 41 on the side surface of the sliding protrusion 35 slides inside the sliding groove 47, so as to ensure the stability of the sliding protrusion 35. When the sliding protrusion 35 moves, it contacts the bottom protrusion 45 on the bottom surface of the bearing plate body 36, and pushes the bottom protrusion 45 upward, so that the bearing plate body 36 is slightly shaken up and down through the force spring 44 on the side surface. Because the vibration component moves with the welding assembly, the vibration source is always located below the welding position, so that the welding position always maintains the best vibration effect, and under the action of the pressing assembly, it prevents the excessive vibration effect from being transmitted to other parts of the steel plate and causing damage to the welded parts.

[0021] The auxiliary mechanism also includes a preheating component, which includes: two heating tubes 8, both of which are arranged on one side surface of the top frame 2, an exhaust fan 48 is arranged inside the heating tube 8, a battery 49 is arranged on one side surface of the heating tube 8, a plurality of electric heaters 50 are arranged inside the heating tube 8, a rotating collar 51 is arranged on one side surface of the heating tube 8, a top plate 55 is arranged on the side surface of the rotating collar 51 away from the heating tube 8, and a plurality of air outlets are arranged on the bottom surface of the top plate 55. Tube 52, a connecting air duct 53 is arranged between every two air outlet ducts 52, the upper and lower sides of the connecting air duct 53 are both air outlet channels, a meshing tooth groove 54 is arranged at the center of the top plate body 55, a meshing gear cylinder 57 is arranged on the upper surface of the meshing tooth groove 54, a control motor 56 is arranged on one side surface of the meshing gear cylinder 57, and the control motor 56 is arranged inside the top frame 2, and a temperature detector 14 and a trigger button 15 are also arranged on the bottom surface of the top frame 2, and there is an electrical connection between the trigger button 15 and the data processor 30; The preheating component is used to start when the steel plate is too thick. When the trigger button 15 on the bottom of the top frame 2 is not triggered after the load-bearing component rises, the data processor 30 does not receive the signal of the trigger button 15, and it can be determined that the steel plate original is too thick. At this time, the exhaust fan 48 inside the heating tube body 8 is driven by the signal of the data processor 30 to start, and the external air is sucked in. The electric heater 50 inside the heating tube body 8 is also heated immediately to heat the wind sucked in by the exhaust fan 48. The hot wind passes through the heating tube The hot air enters the interior of the connecting air duct 53 after the lifting body 8, and is blown out from the openings of the multiple air outlet ducts 52 and enters through the gap formed by the lifting plate body 12 and the bottom surface of the top frame 2, and contacts the steel plate original to preheat the steel plate original. The air outlet ducts 52 on the side surfaces of the two heating tube bodies 8 are arranged in a staggered manner. When the air outlet duct 52 on one side blows out hot air, it is discharged through the upper and lower air outlet ducts of the connecting air duct 53 on the other side. The temperature detector 14 is always in contact with the surface of the steel plate original and senses the temperature of the steel plate original in real time. When the specified temperature is reached, the preheating assembly stops driving, and welding can be carried out at this time. After the electric heater 50 inside the heating tube body 8 stops starting, the temperature inside the heating tube body 8 gradually decreases. When the welding work is completed, the bearing assembly descends and resets, and the control motor 56 inside the top frame 2 drives the meshing gear cylinder 57 to drive. Through the meshing effect of the meshing gear cylinder 57 and the meshing tooth groove 54, the air outlet duct 52 and the connecting air duct 53 rotate through the rotating ring 51 at the connection with the heating tube body 8. 51 can ensure that when the air outlet duct 52 and the connecting air duct 53 are rotated, it will not affect the entry of hot air into the heating tube body 8. The meshing effect of the meshing gear cylinder 57 and the meshing tooth groove 54 makes the air outlet duct 52 and the connecting air duct 53 rotate downward by forty-five degrees to adjust the blowing angle. At this time, the exhaust fan 48 draws air again and blows air through the air outlet duct 52 to cool the welded steel plate product. As the temperature inside the heating tube body 8 gradually decreases, the temperature of the blown air also gradually decreases, which can produce a gradual cooling effect on the steel plate product.

[0022] The working principle of the present invention is: When in use, if welding is required, the staff will place the steel plate original to be welded on the top of the bearing assembly, and then control the drive motor 6 to start through the staff signal. When the drive motor 6 is started, the meshing threaded rod 7 rotates accordingly, and the meshing effect of the meshing threaded rod 7 and the meshing plate 29 causes the data processor 30 to move with the fixed plate body 25 above the fixed top pipe 5, and stop after reaching one end of the fixed top pipe 5. Then, the push motor 26 is driven according to the signal to push the sliding frame 28 to one side. Then, the laser welding head 31 is lowered by the action of the hydraulic rod arranged above it, and is connected with the pressing assembly by the side plug block 32 on its side. At this time, the preparation process is completed. Then, the staff can use the laser welding head 31 to perform the welding process on the steel plate original, and the drive motor 6 immediately rotates in the opposite direction to drive the laser welding head 31 to move on the surface of the steel plate and complete the welding work. The auxiliary mechanism is started synchronously during the welding work, and has the effect of improving the welding effect. The pressing and fixing component is used to provide an additional fixing effect on the surface of the steel plate when performing welding work. In the preparation stage of welding work, the side insert block 32 of the welding component comes into contact with the limiting plate body 9 during movement and then stops. Subsequently, when the laser welding head 31 descends, the side insert block 32 on its side surface will be inserted into the insert sleeve 16 from above. At this time, the laser welding head 31 is located at the center of the four weighting blocks 19. When the welding work starts, during the movement of the welding component, the pressing and fixing component, through the combination effect of the insert sleeve 16 and the side insert block 32, will drive the bottom bracket 18 to slide and follow inside the fixed pressure plate 3 as the welding component moves, so that the laser welding head 31 is always located at the center of the four weighting blocks 19 for welding. During the welding process, the four weighting blocks 19 will apply additional weight to the welding position area of ​​the steel plate, and absorb excess vibration through the buffer layer 20, so that the vibration effect generated by the vibration component is more concentrated on the current welding position, and will not be transmitted to other parts of the steel plate. The plate body component is used to place the steel plate original before the welding work starts. Before the welding work starts, the staff places the steel plate original on the top of the bearing plate body 36. Then, when the welding work is carried out, the electric telescopic rod 33 is driven to start by the staff signal, and the lifting plate body 13 is driven to rise, and the lifting plate body 12 is driven to rise synchronously. The side slider 37 on the side surface of the lifting plate body 12 slides inside the slideway. With the rise of the lifting plate body 13, the lifting plate body 12 is finally fitted with the bottom surface of the top frame body 2, and then the welding work can be carried out. If the lifting plate body 12 fails to fit with the bottom surface of the top frame body 2 successfully, it can be judged that the steel plate is too thick. The preheating component is immediately started to preheat the steel plate original. After the preheating work is completed, the welding work can be completed normally. During the welding process, the vibration component applies a certain vibration force to the steel plate original. Before the welding work begins, when the welding assembly reaches one side of the fixed top pipe 5 and completes the connection with the pressing assembly, the telescopic motor 24 at one end of the connecting rod 4 is started according to the signal of the staff, and drives the lower support rod 22 to descend. When the light detection head 23 at the end of the lower support rod 22 is parallel to the positioning light lamp 40, the laser emitted by the positioning light lamp 40 will be received by the light detection head 23, and the lower support rod 22 will stop driving and transmit the signal to the data processor 30. Subsequently, the small motor 39 is driven after receiving the driving signal sent by the data processor 30, and the meshing effect of the small threaded rod 42 and the meshing block 38 causes the sliding convex strip 35 to move on the bottom surface of the lifting plate body 12. During the movement process In the embodiment, the positioning light 40 and the light detection head 23 always maintain the sensing state, so as to ensure that the moving speed of the sliding protrusion 35 is the same as that of the welding assembly, and the sliding side frame 41 on the side surface of the sliding protrusion 35 slides inside the sliding groove 47, so as to ensure the stability of the sliding protrusion 35. When the sliding protrusion 35 moves, it contacts the bottom protrusion 45 on the bottom surface of the bearing plate 36, and pushes the bottom protrusion 45 upward, so that the bearing plate 36 is slightly shaken up and down through the force spring 44 on the side surface. Because the vibration component moves with the welding assembly, the vibration source is always located below the welding position, so that the welding position always maintains the best vibration effect, and under the action of the pressing assembly, it prevents the excessive vibration effect from being transmitted to other parts of the steel plate and causing damage to the welded parts; The preheating component is used to start when the steel plate is too thick. When the trigger button 15 on the bottom surface of the top frame 2 is not triggered after the carrying component rises, and the data processor 30 does not receive the signal of the trigger button 15, it can be determined that the steel plate original is too thick. At this time, the exhaust fan 48 inside the heating tube body 8 is driven by the signal of the data processor 30 and starts to draw in the external air. The electric heater 50 inside the heating tube body 8 is also heated immediately to heat the wind sucked in by the exhaust fan 48. After passing through the heating tube body 8, the hot air enters the interior of the connecting air duct 53, and is blown out from the openings of the multiple air outlet ducts 52 and enters through the opening where the lifting plate body 12 and the bottom surface of the top frame 2 are not in contact, and contacts the steel plate original. The parts are in contact with each other to preheat the steel plate original. The temperature detector 14 is in contact with the surface of the steel plate original and senses the temperature of the steel plate original in real time. When the specified temperature is reached, the preheating component stops driving, and welding can be carried out at this time. After the electric heater 50 inside the heating tube body 8 stops starting, the temperature inside the heating tube body 8 gradually decreases. When the welding work is completed, the load-bearing component descends and resets. The control motor 56 inside the top frame 2 drives the meshing gear cylinder 57 to drive. Through the meshing effect of the meshing gear cylinder 57 and the meshing tooth groove 54, the air outlet pipe 52 and the connecting air pipe 53 are rotated downward by forty-five degrees. At this time, the exhaust fan 48 draws air again and blows air through the air outlet pipe 52 to cool the welded steel plate product.
