DETAILED DESCRIPTION

[0028] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and a specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0029] Example 1

[0030] The utility model proposes a new type of gravure roller automatic submerged arc welding machine to improve the working efficiency and welding seam quality of arc welding machines. Figure 1 As shown, a first welding groove 11 matching the weld seam of the plate roller is provided on the base 1 of the automatic submerged arc welding machine. The plate roller to be welded is arranged below the base 1, and its weld seam matches and aligns with the first welding groove 11.

[0031] A linear guide 4 is provided on one side of the machine base 1 along the length direction of the first welding groove 11, and a lead screw 5 is provided inside the linear guide 4 along its length direction, and the lead screw 5 is driven by a drive motor 7 provided on one side thereof. The welding head 2 of the automatic submerged arc welding machine cooperates with the lead screw 5 through a slider 6 and is movably connected to the linear guide 4. A conductive copper rod 3 is provided on the side of the welding head 2 close to the machine base 1, and the position of the conductive copper rod 3 matches the first welding groove 11. The lead screw 5 is driven to rotate by the drive motor 7, and the welding head 2 is driven to reciprocate along the linear guide 4 through the slider 6, and then the welding of the plate roller weld located in the first welding groove 11 is completed through the conductive copper rod 3.

[0032] On the machine base 1, a laser emitter 8 is arranged at one end of the first welding groove 11. The laser emitter 8 emits visible laser in a straight line along the length direction of the first welding groove 11, hitting the plate roller weld and the welding head 2 and the conductive copper rod 3 in the first welding groove 11, so as to facilitate the operator to calibrate the position of the plate roller and the welding machine.

[0033] A segmented pressing device 9 for fixing and pressing the weld of the plate roller is arranged between the machine base 1 and the plate roller to be welded. The segmented pressing device 9 is provided with a second welding groove 91 matching the weld of the plate roller. Among them, a plurality of pairs of pressing cylinders 10 are arranged on both sides of the second welding groove 91 on the segmented pressing device 9. The utility model improves the original whole pressing groove into segmented pressing: 20 small cylinders are added for segmented pressing, which solves the previous problem that the two ends are tight but the middle is not tight.

[0034] In order to realize full automation of the equipment, the welding head 2, the driving motor 7 in the linear guide 4 and the multiple pairs of clamping cylinders 10 of the segmented clamping device 9 are connected to the PLC for control. The PLC is connected to a touch screen for displaying welding status data and receiving welding parameter input. All actions of the submerged arc welding equipment are connected in series through the PLC and the touch screen. The head of the welding plate roller is placed in a fixed position each time, and the length of the plate roller is input through the touch screen. After starting, the submerged arc welding gun automatically moves to the starting position to start welding, and automatically stops when welding to the end of the plate.

[0035] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
