Description

Technical Field

[0001] The utility model relates to the technical field of steel structure electric welding, and more specifically, to an electric welding machine for steel structures. Background Art

[0002] Under the existing technical background, electric welding machines for steel structures face several major problems, which mainly involve the complexity of operation, the guarantee of welding quality, and the difficulty of equipment maintenance and line management, all of which may affect the efficiency and quality of welding operations.

[0003] First of all, most of the common steel structure welding machines on the market are handheld. Although handheld welding machines provide operational flexibility in some cases, their operation is complicated and not easy to adapt to the needs of assembly line production. Especially when large-scale welding operations with uniform specifications are required, handheld welding machines cannot efficiently meet production needs, resulting in low production efficiency and increased labor and time costs.

[0004] Secondly, in order to ensure the quality of welding, compressed air is usually required to blow away dust, grease and other impurities in the welding area before and during welding. This step is an important measure to ensure the cleanliness of the weld and reduce welding defects. However, in existing equipment, the connection and release operations of the pipes used to transmit compressed air are usually cumbersome, which not only affects the convenience of operation, but also increases the difficulty of maintaining and upgrading the pipeline system, which may affect production efficiency and maintenance costs.

[0005] In addition, large electric welding equipment usually needs to connect multiple power lines and control lines during use to ensure the normal operation of the equipment. However, existing devices often do not provide effective line management and storage solutions, resulting in messy line layout, which not only affects the cleanliness of the working environment, but also may increase safety risks. The messy lines not only make the workplace look unprofessional, but may also cause line damage or poor contact of wires, further affecting the stable operation and service life of the equipment.

[0035] In this embodiment, when the equipment is needed to weld steel structure products, the products are first placed at the corresponding position in the fixed frame 1, and then the hydraulic cylinder 15 is opened synchronously. The hydraulic cylinder 15 drives the lifting frame 5 to descend through the hydraulic rod 16 connected to the output end.

[0037] A rubber ring 25 is disposed on the outer side of the plug-in tube 18 , and the rubber ring 25 is detachably installed in the sleeve 22 .

[0038] The plug-in mechanism includes a plug-in frame 26 and a plug-in slot 27 . The plug-in slot 27 is arranged outside the plug-in tube 18 . One end of the plug-in frame 26 is inserted into the plug-in slot 27 . Both ends of the plug-in frame 26 are fixedly connected to the matching rod 19 .

[0039] A tension spring 28 is provided on the inner side of the plug-in frame 26 , and the other end of the tension spring 28 is connected to the outer side of the sleeve 22 .

[0040] A fixed plate 29 is disposed on the outer side of the sleeve 22 , a movable plate 30 is disposed on the outer side of the rotating sleeve 21 , a spring 31 is disposed on one side of the fixed plate 29 , and the other end of the spring 31 is connected to the movable plate 30 .

[0041] More specifically, when it is necessary to connect the external pipe to the delivery pipe 14, the springs 31 arranged on both sides are pulled, the springs 31 are stretched, and the movable plate 30 is driven to move, and then the movable plate 30 drives the rotating sleeve 21 to rotate, and then the rotating sleeve 21 lifts the matching rod 19 through the matching block 20, and then the matching rod 19 drives the plug-in frame 26 to move outward, and at the same time, the plug-in frame 26 drives the tension spring 28 arranged on the inside to stretch, when the spring 31 can no longer be pulled, the tension spring 28 is stretched to the limit, and at the same time, the inner side of the plug-in frame 26 is flush with the inner side of the sleeve 22, and then the corresponding end of the plug-in pipe 18 is inserted into the sleeve 22, and one end of the plug-in pipe 18 is pressed against the rubber ring 2 5, and then release the spring 31, the spring 31 can drive the movable plate 30 to reset, and then the movable plate 30 will drive the rotating sleeve 21 and the matching block 20 to reset, because the matching rod 19 loses the limit of the matching block 20, the tension spring 28 will drive the plug-in frame 26 and the matching rod 19 to reset, due to the unique slope structure in the plug-in slot 27, when the tension spring 28 is completely reset, one end of the plug-in frame 26 will be completely inserted into the plug-in slot 27 and drive the plug-in tube 18 to press the rubber ring 25, and at the same time, the multiple rubber rings 23 arranged on the outside of the plug-in tube 18 will be snapped into the corresponding slots 24 in turn, so as to achieve the rapid connection of the delivery pipe 14 while ensuring the high sealing of the connection.

[0042] In summary, when the overall equipment is in use or running: when the equipment needs to be used to weld steel structure products, first place the product at the corresponding position in the fixed frame 1, and then open the hydraulic cylinder 15 synchronously, the hydraulic cylinder 15 drives the lifting frame 5 to descend through the hydraulic rod 16 connected to the output end, and after descending to the corresponding height, close the hydraulic cylinder 15, and then open the corresponding cylinder 2 in turn, the cylinder 2 drives the welding head 4 to move through the piston rod 3 connected to the output end, and at the same time turn on the power of the electric welder, and perform electric welding through the welding head 4. When it is necessary to organize the cables of the equipment, first turn the screw 7 through the knob 10. Since the sliding sleeve 8 and the screw 7 are movably connected through threads, and at the same time, the guide rod 9 limits the guide of the sliding sleeve 8. The sliding sleeve 8 will slide along the lead screw 7 and the guide rod 9 in the mounting frame 6 due to the effect of the position. Since the wire clamping plate 11 is connected to the mounting frame 6 through the connecting plate 12, one side of the wire clamping plate 11 will slide relatively in the sliding groove 13 at this time. Due to the special inclined design of the sliding groove 13, when the sliding sleeve 8 slides, the wire clamping plate 11 will slide relatively along the sliding groove 13 and diffuse outward at the same time. Then, the cables that need to be integrated are inserted into the corresponding sliding sleeve 8 one by one through the wire entry groove 17, and then the knob 10 is rotated in the opposite direction to reset the sliding sleeve 8. Then the wire clamping plate 11 will reset and gather inward. When the wire clamping plate 11 completely clamps the cables inside the sliding sleeve 8, stop turning the knob 10.

[0043] When it is necessary to connect the external pipe to the delivery pipe 14, the springs 31 arranged on both sides are pulled, the springs 31 are stretched, and the movable plate 30 is driven to move, and then the movable plate 30 drives the rotating sleeve 21 to rotate, and then the rotating sleeve 21 lifts the matching rod 19 through the matching block 20, and then the matching rod 19 drives the plug-in frame 26 to move outward, and at the same time, the plug-in frame 26 drives the tension spring 28 arranged on the inside to stretch, when the spring 31 can no longer be pulled, the tension spring 28 is stretched to the limit, and at the same time, the inner side of the plug-in frame 26 is flush with the inner side of the sleeve 22, and then the corresponding end of the plug-in tube 18 is inserted into the sleeve 22, and one end of the plug-in tube 18 is made to abut against the rubber ring 25, Then release the spring 31, the spring 31 can drive the movable plate 30 to reset, and then the movable plate 30 will drive the rotating sleeve 21 and the matching block 20 to reset. Since the matching rod 19 loses the limit of the matching block 20, the tension spring 28 will drive the plug-in frame 26 and the matching rod 19 to reset. Due to the unique slope structure in the plug-in groove 27, when the tension spring 28 is fully reset, one end of the plug-in frame 26 will be fully inserted into the plug-in groove 27 and drive the plug-in tube 18 to press the rubber ring 25. At the same time, the multiple rubber rings 23 arranged on the outside of the plug-in tube 18 will be engaged in the corresponding card grooves 24 in turn, thereby achieving quick connection of the delivery pipe 14 while ensuring a high degree of sealing at the connection.
