[0025] In addition, the terms "first", "second", and the like, do not denote any quantity or importance, but rather are used to distinguish one element from another, and are not intending to indicate a particular importance of the referred features. Thus, a feature defined with "first" or "second" can include one or more of the features implicitly or explicitly. In the description of the application, the meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0026] Referring to Figures 1 to 4 the operation rotating table for sheet metal processing, it comprises a base frame 1, a workbench 2, a portal frame 3 and a mounting frame 4, wherein the workbench 2 and the portal frame 3 are both arranged on the base frame 1, and the portal frame 3 is across the workbench 2. The mounting frame 4 is arranged on the portal frame 3, and the mounting frame 4 is used for mounting a welding head of a handheld welding machine or a cutting head of a handheld cutting machine. Preferably, the handheld welding machine is a handheld laser welding machine, and the handheld cutting machine is a handheld plasma cutting machine.

[0027] As shown in Figure 1 , the mounting frame 4 comprises an upper mounting frame 41, a connecting frame 43 and a lower mounting frame 42. The upper mounting frame 41 is mounted on the crossbeam of the portal frame 3, and the upper mounting frame 41 can move back and forth along the crossbeam and can be locked on the crossbeam. The upper part of the connecting frame 43 is rotatable and lockable with the upper mounting frame 41 in the vertical direction, so as to facilitate the adjustment of the included angle relative to the upper mounting frame 41. The lower mounting frame 42 is movably connected with the lower part of the connecting frame 43, and the lower mounting frame 42 is provided with a mounting position for mounting the welding head or the cutting head, so as to realize the linear movement and facilitate the linear cutting of the sheet metal. In addition, the portal frame 3 can be adjusted in height. By loosening the hand screw, the crossbeam is moved up and down to the appropriate position and then tightened, so as to facilitate the adjustment of the height of the welding head or the cutting head.

[0028] For convenient operation, the lower mounting frame 42 is also provided with a switch mechanism at the installation position, which can control the welding head or cutting head switch button. The switch mechanism is mainly controlled by the mechanical structure to control the switch button on the welding head or cutting head. Further, the action of the switch mechanism is connected with the pedal 10 provided on the base frame 1 through a steel wire 20, so as to realize the foot control of the switch mechanism, and the hands are free to operate the linear movement of the lower mounting frame 42. Of course, a more simple structure can be adopted, and the gun-shaped welding head or cutting head is directly bound on the lower mounting frame 42. When holding the welding head or cutting head, the switch button can be directly pressed, and the lower mounting frame 42 can be pulled to move linearly together with the welding head or cutting head. For the metal plate with complex structure, the welding head or cutting head needs to be removed and held to weld or cut.
