The conventional pressing mechanism 10 normally presses the member to be pressed directly by using the pressing plate 310. According to the technical scheme of the utility model, the pressing pieces 320 are used for pressing the to-be-pressed piece, and the pressing pieces 320 are elastically connected with the pressing plate 310 through the elastic pieces 330, so that the pressing force of the pressing device 300 on the to-be-pressed piece can be increased, the pressing device 300 can press the to-be-pressed piece, and the pressing mechanism 10 can press the to-be-pressed piece.
Referring to fig. 4 and 5, in an embodiment, the pressing device 300 further includes a connecting column 340, one end of the connecting column 340 is connected to the pressing member 320, the other end of the connecting column 340 is movably connected to the pressing plate 310, and the elastic member 330 is sleeved outside the connecting column 340.

Specifically, the shape of the pressing plate 310 is configured to be rectangular, and the pressing member 320 extends in the width direction of the pressing plate 310, so that more pressing members 320 can be arranged, thereby enhancing the pressing force on the member to be pressed. The pressing piece 320 is also rectangular, and in order to increase the stability of the pressing piece 320, the two ends of the pressing piece 320 in the length direction are respectively connected with the connecting columns 340, the outer side of each connecting column 340 is sleeved with the spring 330, and the stability of the pressing piece 320 can be further increased by the two connecting columns 340.
Referring to fig. 5, it is worth mentioning that two ends of the pressing member 320 along the length direction thereof are provided with protrusions 321, and the protrusions 321 are used for pressing the member to be pressed. Specifically, since the member to be pressed is also rectangular in shape, the welding device mainly welds four sides to the member to be pressed, and therefore the pressing member 320 mainly presses the four sides close to the member to be pressed, and therefore, the pressing member 320 is provided with the protruding blocks 321 at two ends along the length direction thereof, and the protruding blocks 321 are mainly used for pressing the four sides close to the member to be pressed.
Referring to fig. 4 and 5, it is considered that, since the pressing member 320 can move towards the direction of the pressing plate 310, and the other end of the connecting column 340 is movably connected to the pressing plate 310, when the pressing member 320 moves towards the direction of the pressing plate 310, the connecting column 340 protrudes out of the upper surface of the pressing plate 310, so that the connecting point between the connecting column 340 and the pressing plate 310 cannot be directly connected to the driving device 200, and two plates are required to be switched. In view of this, to solve this problem, it is optional to provide the pressing device 300 with a first mounting plate 350 and a second mounting plate 360, the first mounting plate 350 extending in the horizontal direction and the second mounting plate 360 extending in the vertical direction; the first mounting plate 350 is connected to the driving shaft of the driving device 200, and one side of the second mounting plate 360 is connected to the first mounting plate 350 and the other side is connected to the pressing plate 310, thereby solving the aforementioned problems.

Specifically, when welding materials, the materials are generally moved to a designated position by a feeding device and then welded by a welding head. For example, in welding a steel frame and a steel plate, it is general that the steel frame and the steel plate are placed on the placing table 30 by a loading device, then the placing table 30 is moved to a specified position, and the pressing mechanism 10 presses the steel frame and the steel plate on the placing table 30, and then the welding head starts welding work.

Specifically, when the pressing device 300 rotates along with the placing table 30, and then the laser welding head welds the material, the rotated pressing device 300 needs to rotate back to the initial position before welding the next material, so as to accurately press the next material, and therefore, the zero returning device 700 can restore the pressing device 300 to the initial state, so that the pressing device 300 can accurately press the next material.
