When the axis of the turntable 2 is arranged in the horizontal direction, the axis direction of the turntable 2 is defined as the first direction; the pulley 4 is arranged on one side of the fixed frame 1, and the position of the pulley 4 relative to the fixed frame 1 has the freedom to be adjusted in the first direction; the lifting frame 5 is installed on the pulley 4, and the position of the lifting frame 5 on the pulley 4 has the freedom to be adjusted in the height direction; the welding frame 7 is slidably arranged on the lifting frame 5 along the first direction; the driving assembly 9 is installed between the welding frame 7 and the lifting frame 5, and is used to push the welding frame 7 to move on the lifting frame 5; the first welding gun 71 is installed on the welding frame 7, and the welding joint on the first welding gun 71 is arranged toward the axis of the chuck 3; the second welding gun 72 is installed on the welding frame 7, and is arranged at an angle with the first welding gun 71, and the welding joint on the second welding gun 72 is arranged toward the axis of the chuck 3; the weld tracker 8 is installed on one side of the fixed frame 1, and is used to detect the welds on the inner and outer rings of the pipeline.
[0035] Compared with the prior art, the real-time collaborative perception robot pipeline adaptive welding system provided in this embodiment is provided with a fixed frame 1, a turntable 2 is rotatably provided on the fixed frame 1, and a chuck 3 for clamping the pipeline is installed on the turntable 2. The pulley 4 is slidably provided on one side of the fixed frame 1 along the first direction, and a lifting frame 5 is installed on the pulley 4, and a welding frame 7 is installed on the lifting frame 5. The welding frame 7 can reciprocate along the first direction on the lifting frame 5 through the drive of the driving assembly 9. In addition, a first welding gun 71 and a second welding gun 72 are installed on the welding frame 7, and the first welding gun 71 is used for bottom welding, and the second welding gun 72 is used for cover welding. In addition, a weld tracker 8 is installed on one side of the turntable 2 on the fixed frame 1. In the present application, when welding the pipeline, the spot-welded pipeline is fixed to the chuck 3, and the pipeline position is adjusted so that the weld is within the detection range of the weld tracker 8. During the rotation of the turntable 2, the weld tracker 8 first detects the width of the inner ring weld of the pipeline and feeds back to the controller. The controller controls the swing amplitude and swing position of the drive assembly 9 according to the width of the weld at the detection position when the detection position moves to the first welding gun 71, so as to achieve the bottom welding at the weld. After the bottom welding is completed, the width of the outer ring weld of the pipeline is detected by the weld tracker 8, and the feedback is given to the controller. The controller controls the swing amplitude and swing position of the drive assembly 9 according to the width of the weld at the detection position when the detection position moves to the second welding gun 72, so as to achieve the cover welding. Through a single clamping, the bottom and cover welding can be achieved. In addition, the welding process is uninterrupted, the operation is convenient, and the welding efficiency of pipeline welding is effectively improved.
[0036] Specifically, in this embodiment, the weld tracker 8 and the method for the controller to control the drive assembly 9 both adopt the existing technology, which will not be elaborated here. The weld tracker 8 is electrically connected to the controller, and the controller is electrically connected to the drive end of the drive assembly 9. It is used to control the working state of the drive end. During the welding process, the welding joints of the first welding gun 71 and the second welding gun 72 are both arranged along the radial direction of the pipeline. By detecting the angle between the position of the weld tracker 8 and the first welding gun 71 and the second welding gun 72 and combining the inner diameter and outer diameter of the pipeline, it can be calculated that when the weld tracker 8 detects a certain length of the weld, the first welding gun 71 or the second welding gun is started to switch between the working state and the stop state.
[0037] Specifically, in this embodiment, the weld tracker is also used to detect the position and length of the weld, and convert the weld detection position information into a signal and transmit it to the controller. The controller controls the driving component 9 to drive the welding frame 7 to move to the corresponding position, and controls the amplitude of the reciprocating motion of the welding frame 7 along the first direction during the welding process to move with the detected weld width, thereby realizing automatic welding operations.
[0038] Preferably, in this embodiment, during the pipeline welding process, the weld tracker 8 first detects the width and length of the weld on the inner wall of the pipeline. Then, the welding base operation is performed. After the base operation is completed, the weld tracker 8 detects the width and length of the weld on the outer wall of the pipeline, and then performs the cover welding operation. This prevents the pipeline from being deformed during the base welding process and affecting the subsequent cover operation.

Thus, the limit block realizes the fixing of the position of the trolley 4.
[0040] Specifically, in this embodiment, a gear bar is fixedly mounted on the pulley 4, the length direction of the gear bar is arranged in the vertical direction, and a gear meshing with the gear bar is rotatably arranged on the lifting frame 5. A motor for driving the gear to rotate is also installed on the lifting frame 5, and the lifting frame 5 can be driven to move up and down by starting the motor.
[0041] Preferably, in this embodiment, the axis of the turntable 2 is coaxially arranged with the axis of the chuck 3. When the axis of the turntable 2 is arranged in the horizontal direction, the orientations of the welding joints of the first welding gun 71 and the second welding gun 72 are both arranged in the radial direction of the turntable 2. At the same time, the orientation of the detection end of the weld tracker 8 is also arranged in the radial direction of the turntable 2. The welding length and the welding starting point and end point of the first welding gun 71 and the second welding gun 72 can be effectively calculated through the outer diameter and inner diameter of the pipeline.

A crossbeam 73 is fixedly mounted on the welding frame 7, and the first welding gun 71 and the second welding gun 72 are installed on the crossbeam 73 along the length direction of the crossbeam 73, respectively, and the positions of the first welding gun 71 and the second welding gun 72 on the crossbeam 73 can be adjusted along the length direction of the crossbeam 73. The axial direction of the welding joint pipe of the first welding gun 71 and the second welding gun 72 can be achieved by adjusting the positions of the first welding gun 71 and the second welding gun 72 on the crossbeam 73. Ensure the stability of welding.
[0043] In some embodiments, the cross beam 73 may be formed as follows: Figure 1 , Figure 2See also Figure 1 , Figure 2 A moving block 733 is installed between the first welding gun 71 and the second welding gun 72 and the crossbeam 73, respectively. A rotating disk 734 is installed on the moving block 733. The rotating disk 734 has a degree of freedom to adjust along the pitch angle on the moving block 733, and the rotating axis of the rotating disk 734 is arranged along the first direction. The first welding gun 71 and the second welding gun 72 are respectively installed on the rotating disks 734 on the two moving blocks 733. A moving block 733 is slidably arranged on the crossbeam 73 along the length direction of the crossbeam 73, and a gear bar is fixedly installed on one side of the crossbeam 73, and the length direction of the gear bar is arranged along the length direction of the crossbeam 73. A gear that meshes with the gear bar is rotatably arranged on the moving block 733, and a handle that is convenient for rotating the gear is fixedly installed on the gear.

A rotating disk 734 is also installed on the moving block 733, and the axis of the rotating disk 734 on the moving block 733 is arranged along the first direction. A worm 112 is rotatably mounted on the crossbeam 73, and a worm wheel 111 is fixedly mounted on the rotating disk 734. The worm wheel 111 is coaxially arranged with the rotating disk 734, and the worm 112 and the worm wheel 111 are meshed with each other. The worm 112 can be rotated to drive the worm wheel 111 to rotate, thereby adjusting the angle of the rotating disk 734. In the present application, the positions of the first welding gun 71 and the second welding gun 72 on the crossbeam 73 can be adjusted, and at the same time, the angles of the first welding gun 71 and the second welding gun 72 can also be adjusted. The positions of the first welding gun 71 and the second welding gun 72 can be adjusted during the welding process according to pipes of different sizes to ensure a certain welding treatment.
[0044] In a preferred embodiment, the crossbeam 73 includes a fixed beam 731 fixedly mounted on the welding frame 7 and a sliding beam 732 slidably mounted on the fixed beam 731 along the first direction. The first welding gun 71 and the second welding gun 72 are mounted on the fixed beam 731 and the sliding beam 732 respectively. During the welding process, the first welding gun 71 is located in front of the second welding gun 72. A screw connected to the sliding beam 732 is also rotatably mounted on the welding frame 7, and a synchronous motor for driving the screw to rotate is also mounted on the welding frame 7. The synchronous motor is electrically connected to the controller, and the working state of the synchronous motor can be controlled by the controller. Through the setting of the sliding beam 732, the position of the second welding gun 72 relative to the first welding gun 71 in the first direction can be freely adjusted. During the pipeline welding process, by adjusting the positions of the first welding gun 71 and the second welding gun 72, the welding joints of the first welding gun 71 and the second welding gun 72 are all arranged along the radial direction of the pipeline, so that the relative positions of the detection position of the weld tracker 8 and the first welding gun 71 and the second welding gun 72 can be determined according to the sizes of the inner diameter and outer diameter of the pipeline. Therefore, the weld seams of the outer ring and the inner ring of the pipeline are detected simultaneously during the detection process of the weld seam tracker 8, the position of the first welding gun 71 is adjusted by adjusting the position of the welding frame 7 through the driving component 9, and the position of the second welding gun 72 is adjusted by compensating the displacement of the sliding beam 732 along the first direction. When welding the pipeline, the first welding gun 71 and the second welding gun 72 can be operated synchronously, the first welding gun 71 performs base welding at the front, and the second welding gun 72 performs cover welding at the back, which effectively improves the welding efficiency during the pipeline welding process.
[0045] Specifically, in the present embodiment, the first welding gun 71 and the holiday welding gun 72 are arranged at an angle along the circumferential direction of the turntable 2 .
[0046] In some embodiments, the first welding gun 71 and the second welding gun 72 can be used as follows: Figure 2 See the structure shown. Figure 2 The positions of the first welding gun 71 and the second welding gun 72 on the rotating disk 734 have the freedom to be adjusted in the direction close to or away from the axis of the chuck 3. An adjustment seat is fixedly installed on the rotating disk 734, and a mounting plate for mounting the first welding gun 71 or the second welding gun 72 is slidably arranged on the adjustment seat.

[0047] Preferably, in this embodiment, a synchronous motor for rotating the lead screw 91 is also installed on the adjustment seat, and the synchronous motor is electrically connected to the controller. When the first welding gun 71 is required to work, the synchronous motor corresponding to the first welding gun 71 can be controlled to drive the first welding gun 71 to move toward the direction close to the pipeline, and the synchronous motor corresponding to the second welding gun 72 can be controlled to drive the second welding gun 72 to move away from the pipeline; when the second welding gun 72 is working, the first welding gun 71 and the second welding gun 72 are controlled by the controller to move in opposite directions. At the same time, the positions of the working states of the first welding gun 71 and the second welding gun 72 can be adjusted accordingly according to different pipelines during the welding process.
[0048] In some embodiments, the drive assembly 9 may be configured as follows: Figure 3 See the structure shown. Figure 3 The driving assembly 9 includes a lead screw 91 and a driving member 92.

[0049] Specifically, in this embodiment, the initial positions of the first welding gun 71 and the second welding gun 72 can be calibrated by adjusting the position of the welding frame 7 before welding. During the welding process, the controller controls the working state of the driving member 92 according to the position and width of the weld detected by the weld tracker 8, so that the welding frame 7 synchronously drives the first welding gun 71 and the second welding gun 72 to move during the movement along the first direction, thereby realizing the operation of adjusting the position of the first welding gun 71 or the second welding gun 72 in real time according to the detection result of the weld tracker 8.
