[0023] See also Figure 1-5 , an embodiment provided by the utility model:
[0024] A welding machine for fixing a flange group includes a first workbench 1 and a second workbench 2, a limit seat 611 is fixedly installed between the first workbench 1 and the second workbench 2, and a first electric push rod 3 is arranged at one end of the second workbench 2, and a rotating plate 4 is movably installed at one end of the first electric push rod 3, a first motor 111 is arranged on one side of the first workbench 1, and one end of the first motor 111 is connected to a limit plate 112, a plurality of groups of fixing plates 114 are fixedly installed on the outer surface of the limit plate 112, and a cylinder 113 is fixedly installed on the outer surface of the fixing plate 114, one end of the cylinder 113 is connected to a clamping plate 212, and one end of the limit seat 611 is connected to a support seat 411, A groove is provided on the outer surface of the support seat 411, and a movable mechanism is arranged in the groove, and one end of the movable mechanism is connected to the second motor 414, a welding head 413 is fixedly installed on one end of the second motor 414, and one end of the welding head 413 is connected to a welder 412, and the welder 412 is fixedly connected to one side of the support seat 411, and a plurality of groups of second electric push rods 6 are arranged on the top of the limiting seat 611, and the tops of the plurality of groups of second electric push rods 6 are connected to a support plate 7, a plurality of groups of connecting frames 8 are fixedly installed on the top of the support plate 7, and a rotating wheel 9 is movably installed on the top of the plurality of connecting frames 8, a connecting pipe 5 is movably installed on the top of the rotating wheel 9, and one end of the connecting pipe 5 is connected to a flange 711.
[0025] Furthermore, the outer surface of the clamping plate 212 is wrapped with rubber. By wrapping the outer surface of the clamping plate 212 with rubber, not only the friction during clamping is increased, and the clamping stability of the flange 711 is improved, but also scratches or damages that may be caused by direct metal contact are avoided, thereby protecting the surface quality of the flange.
[0026] Furthermore, the outer surface of the limiting plate 112 is provided with multiple groups of sliders 214, the inner walls of the multiple groups of sliders 214 are movably installed with sliding grooves 213, and one end of the sliding grooves 213 is connected to the clamping plate 212. Multiple groups of sliders 214 and sliding grooves 213 are provided on the outer surface of the limiting plate 112, so that the clamping plate 212 can slide freely on the sliders through the sliding grooves, thereby making it easier to adjust the clamping position and force, thereby improving the adaptability and operational flexibility of the equipment.
[0027] Furthermore, the cylinder 113 is fixedly connected to the fixing plate 114 via the connecting plate 211 , and the connecting plate 211 enhances the stability of the installation of the cylinder 113 and reduces the risk of loosening or falling off due to vibration or impact.
[0028] Furthermore, the outer surface of the rotating plate 4 is wrapped with rubber, which not only increases the friction when in contact with the connecting pipe 5, helping to push the connecting pipe more stably, but also reduces the wear on the surface of the connecting pipe, reflecting the awareness of protecting the workpiece.
[0029] Furthermore, the movable mechanism includes two groups of fixed seats 513, and the outer surfaces of the two groups of fixed seats 513 are both provided with circular through grooves, and screw rods 514 are movably installed in the circular through grooves, and a sliding seat 515 is movably installed on the outer surface of the screw rods 514, one end of the sliding seat 515 is connected to the second motor 414, one end of the fixed seat 513 is connected to the third motor 512, and the third motor 512 is fixedly connected to the fixed seat 513. Through the drive of the third motor 512, the screw rod 514 can drive the sliding seat 515 and the welding head 413 to move up and down, thereby meeting the welding requirements of different heights and angles.
[0030] Furthermore, a protection plate 511 is fixedly mounted on one side of the two sets of fixing seats 513 , and the protection plate 511 is the third motor 512 .
[0031] Working principle: First, the flange 711 to be welded is accurately placed in the limit plate 112 on the first workbench 1. Then, by starting multiple groups of cylinders 113, the piston rods of the cylinders push the clamping plate 212 to approach the flange and clamp it tightly, ensuring that the flange remains stable and motionless during the welding process. Then, the connecting pipe 5 to be connected is gently placed on the support plate 7, supported and guided to the appropriate position by multiple groups of rotating wheels 9. The design of the rotating wheel is not only convenient for the placement of the pipeline, but also provides a certain degree of rotational freedom in the subsequent welding process to meet the welding requirements of different angles. The telescopic function of the second electric push rod 6 is used to adjust the overall height and position of the support plate 7 and the rotating wheels 9 thereon and the connecting pipe 5 to ensure that the docking surface of the connecting pipe and the flange 711 is accurate. Then, the first electric push rod 3 is started, and its strong thrust is transmitted to the connecting pipe 5 through the rotating plate 4, pushing it to move in the direction of the flange until the two are tightly engaged together to form a preliminary mechanical connection. After confirming that the connecting pipe and the flange have been firmly docked, the welder 412 in the movable mechanism is activated. The welder drives the screw rod 514 to rotate, driving the sliding seat 515 and the welding head 413 thereon to move up and down along the preset track to the optimal welding position. At the same time, the angle of the welding head 413 is adjusted by the rotation of the second motor 414 to adapt to different welding gaps and direction requirements. After everything is ready, the welding head 413 starts to work, and the joint of the connecting pipe and the flange is efficiently and evenly welded to ensure that the strength and sealing of the joint meet the design requirements, and by driving the first motor 111, the limit plate 112 can be rotated as a whole.
