Robotic welders offer greater efficiency, consistency, and accuracy than manual welding.

[0003] The positioning mechanism of a robotic welding machine is a device used to ensure that the workpiece remains in the correct position during the welding process.

[0022] Example 1: A positioning structure for a robot welding machine, see Figure 1 and Figure 2 , including a support leg 1, a connecting seat 2, a positioning plate 3, an electromagnetic table 4, a support seat 5, a robot welding machine body 6, a support plate 7 and a scanning mechanism.

The four connecting seats 2 are provided with a positioning plate 3 by means of bolt connection. The positioning plate 3 is provided with an electromagnetic table 4. The support plate 7 is slidably provided with a support seat 5. The robot welding machine body 6 is provided on the support seat 5 by means of bolt connection. The scanning mechanism is provided on the support plate 7.

[0023] When welding is required, first turn on the electromagnetic table 4 and place the workpiece on the electromagnetic table 4. After the electromagnetic table 4 is energized, it will adsorb the workpiece, thereby fixing the workpiece on the electromagnetic table 4 and keeping the workpiece in the correct position. Then turn on the scanner 12 to scan the welding position. The scan data is transmitted to the control terminal through the signal transmitter 13. The control terminal starts the robot welding machine body 6 according to the received data and controls the robot welding machine body 6 to weld the workpiece, thereby improving the efficiency and accuracy of welding. When it is necessary to weld different angles of the workpiece, the arc-shaped electric slide 8 is turned on by the control terminal, and the electric slider 9 drives the support seat 5 to move, thereby adjusting the position of the robot welding machine body 6 so that it can weld different angles of the workpiece, thereby avoiding welding dead angles and improving the overall welding effect. After adjusting the robot welding machine body 6 to the appropriate position, the arc-shaped electric slide 8 is closed.

[0024] Example 2: Based on Example 1, please refer to Figure 2 、 Figure 3 and Figure 4 A connecting ring 14 is fixedly connected to the bottom of the positioning plate 3, a supporting disk 17 is fixedly connected to the supporting plate 7, a screw rod 18 is rotatably provided on the supporting disk 17, a support frame 1401 is threadedly provided on the screw rod 18, the lower end of the connecting ring 14 is fixedly connected to the support frame 1401, a driving motor 15 is provided on the support frame 1401 by means of bolt connection, the output shaft of the driving motor 15 is connected to the worm 16 through a coupling, a worm gear 19 is provided at the lower part of the screw rod 18, the worm gear 19 is meshed with the worm 16, and the worm gear 19 is fixedly connected to the support frame 1401.

[0025] When the height of the electromagnetic table 4 needs to be adjusted, the drive motor 15 is turned on, and the output shaft of the drive motor 15 rotates to drive the worm 16 to rotate. Under the action of the meshing of the worm 16 and the worm wheel 19, the worm wheel 19 rotates accordingly. The rotation of the worm wheel 19 causes the support frame 1401 to move upward along the screw rod 18. The upward movement of the support frame 1401 drives the connecting ring 14, the drive motor 15 and the worm 16 to move upward, and then the positioning plate 3 drives the electromagnetic table 4 to move upward, thereby adjusting the height of the electromagnetic table 4 to adapt to different welding requirements.

[0027] When two workpieces need to be welded together, the electric-controlled slide rail 21 is first turned on, so that the electric-controlled slider 22 drives the electric slide 23 to move forward until the electric slide 23 reaches the appropriate position. Then, the electric clamp 24 is turned on, and the electric clamp 24 clamps the workpiece. Then, the electric-controlled slider 22 is controlled to drive the electric slide 23 to move backward so that the two workpieces contact each other, thereby clamping the workpieces without the aid of other tools, thereby improving the use efficiency of the positioning structure.
