By starting the servo motor 2 15, the servo motor 2 15 drives the rotating rod 2 803 and the gear 2 804 to rotate. Since the gear 2 804 is respectively engaged with the two gears 1 802, the gear 1 802 drives the circular block 16 and the welding head 11 to rotate through the rotating rod 1 801, which is beneficial for the user to adjust the angle of the welding head when flipping according to the specifications of the weldment and the protractor 805, thereby improving the applicability of the device.

As shown in Figures 1, 5 and 6, the clamping mechanism 9 includes a clamping block 901, a buffer column 902, a buffer block 903, a buffer spring 904 and a mounting column 905.

First, the weldment is placed on opposite sides of the two clamping blocks 901, and then the servo motor three 23 is started through the controller, so that the servo motor three 23 drives the gear three 22 to rotate. Since the gear three 22 is respectively meshed with the two racks 21, the racks 21 are moved away from or closer to each other in the internal parts of the base 1. At this time, the rack 21 drives the mounting column 905 to move synchronously through the connecting rod 19 and the connecting rod 20, so that the mounting column 905 drives the clamping block 901 to move away from or closer to each other through the buffer column 902. At the same time, when the weldment squeezes the clamping block 901, the clamping block 901 drives the buffer block 903 to perform telescopic movement inside the mounting column 905 through the buffer column 902. At the same time, the buffer spring 904 is squeezed by the buffer block 903 to perform telescopic movement inside the mounting column 905, which is beneficial to effectively avoid the damage of the weldment surface due to excessive clamping force, thereby achieving the effect of buffering and protecting the weldment.

Working principle: First, the user moves the device to the designated location via the handle 5, then places the weldment on opposite sides of the two clamping blocks 901, and then starts the servo motor three 23, so that the servo motor three 23 drives the gear three 22 to rotate. Since the gear three 22 is respectively meshed with the two racks 21, the racks 21 are moved away from or closer to each other in the inner parts of the base 1. At this time, the rack 21 drives the mounting column 905 to move synchronously via the connecting rod one 19 and the connecting rod two 20, so that the mounting column 905 drives the clamping block 901 to move away from or closer to each other via the buffer column 902. At the same time, when the weldment squeezes the clamping block 901, the clamping block 901 drives the buffer block 903 to perform telescopic movement inside the mounting column 905 via the buffer column 902, and at the same time, the buffer spring 904 is squeezed by the buffer block 903 to perform telescopic movement inside the mounting column 905, so that the clamping block 901 performs buffer protection on the weldment. Secondly, according to the position of the weldment, the electric Push rod 6, at this time, the electric push rod 6 drives the installation bar 10 to move forward and backward, thereby the installation bar 10 drives the welding head 11 to move forward and backward, and then the servo motor 1 701 is started, so that the servo motor 1 701 drives the threaded rod 702 to rotate, and at this time the threaded rod 702 drives the threaded block 703 to move left and right inside the installation bar 10, so that the threaded block 703 drives the moving block 704 to move left and right on the support rod 705, and at this time the moving block 704 drives the cylinder 13 to move left and right, and then the cylinder 13 is started, so that the cylinder 13 drives the welding head 11 to move left and right and lift, finally, by starting the servo motor 2 15, the servo motor 2 15 drives the rotating rod 2 803 and the gear 2 804 to rotate, because the gear 2 804 is respectively engaged with the two gears 1 802, so that the gear 1 802 drives the circular block 16 and the welding head 11 to rotate through the rotating rod 1 801, thereby the welding angle of the welding head 11 can be automatically adjusted.
