Three plasma cutting machine bodies are arranged on one side above the workbench. The output end of the servo motor is provided with a transmission component, and the transmission component is in transmission connection with the eight pressing heads and the three plasma cutting machine bodies. When the servo motor operates, power is output to the eight pressing heads and the three plasma cutting machine bodies through the transmission component, so that the eight pressing heads move down to press the marine generator metal plate, and the three plasma cutting machine bodies synchronously cut the marine generator metal plate.

[0005] Preferably, the transmission component includes a driving sprocket and a rotating shaft. The driving sprocket is fixedly installed at the output end of the servo motor. The rotating shaft is rotatably installed at the other end of one side of the support frame. One end of the rotating shaft is fixedly installed with a driven sprocket, and a chain is meshed and connected between the driving sprocket and the driven sprocket.

[0006] Preferably, threaded rods are fixedly installed on one side of both the driven sprocket and the driving sprocket. One end of each threaded rod is rotatably installed with a positioning seat, and the tops of the two positioning seats are fixedly connected to the bottom of the workbench. Threaded sleeves are threadedly connected to the surfaces of the two threaded rods. A connecting beam is fixedly installed between the threaded sleeves. The middle of the top of the connecting beam is fixedly installed with a connecting frame, and one side of the connecting frame is fixedly connected to the three plasma cutting machine bodies.

[0007] Preferably, two sliding sleeves are fixedly installed at the lower part of the connecting frame. Slide rods are inserted into the interiors of the two sliding sleeves. One end of each of the two slide rods is fixedly connected to one side of the workbench.

The two ends of the limiting rod are respectively fixedly installed with a fixing plate and a fixing frame. The top of the fixing plate is fixedly connected to the bottom of the workbench, and one end of the fixing frame is fixedly connected to the other side of the workbench.

[0010] Preferably, insertion rods are fixedly installed at both ends of the upper part of the transmission beam, slots are formed at both ends of the upper part of the workbench, the two insertion rods are inserted into the two slots, springs are sleeved on the surfaces of the two insertion rods, bent rods are fixedly installed at the tops of the two insertion rods, and both ends of the two springs are fixedly connected to the bent rods and the top of the workbench respectively.

[0011] Preferably, support arms are fixedly installed at the ends of the two bent rods far away from the insertion rods, support bars are fixedly installed between both ends of the two support arms, four pressing rods are respectively fixedly installed at the lower parts of the two support bars, and the bottoms of the eight pressing rods are fixedly connected to eight pressing heads.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) During work, an operator places the metal plate of the marine generator set into the placement groove, and then starts the servo motor to drive the driving sprocket to rotate. When the driving sprocket rotates, it drives the driven sprocket to rotate along the rotating shaft through the chain. When the driven sprocket and the driving sprocket rotate, they both drive the threaded rod to rotate along the positioning seat. When the two threaded rods rotate, they drive the connecting beam to move through the two threaded sleeves. When the connecting beam moves, it drives the pushing strip to move through the two fixing rods and the installation strip. When the pushing strip moves, it drives the limiting sleeve to slide on the surface of the limiting rod, increasing the stability of the pushing strip during movement; When the pushing strip moves, it quickly squeezes the transmission beam to move downward through the inclined groove. When the transmission beam moves downward, it drives the two insertion rods to move downward along the two slots, and at the same time drives the two bent rods to move downward. When the two bent rods move downward, they will squeeze the two springs to contract. When the two bent rods move downward, they both drive the two support bars to move downward through the two support arms. When the two support bars move downward, they drive the eight pressing heads to move downward through the eight pressing rods to tightly press and fix the metal plate; When the connecting beam moves, it drives the three plasma cutting machine bodies to move through the connecting frame. While the connecting beam moves, it drives the two sliding sleeves to slide along the surfaces of the two sliding rods, increasing the stability of the connecting frame and the three plasma cutting machine bodies during movement; (2) Since the front end of the pushing strip is inclined and the subsequent part is straight, the pushing strip can continue to move while pushing the eight pressing heads to tightly press the metal plate, so as to move the three plasma cutting machine bodies to cut the metal plate while ensuring the pressing stability of the metal plate; At the same time, since the three plasma cutting machine bodies can cut the metal plate into four parts, and the eight pressing heads can tightly press both ends of the four parts at the same time to ensure the stability of the metal plate during the cutting process; (3) The pressing and fixing method adopted by the present cutting device can effectively ensure the stability during metal cutting, and the gaps generated during cutting will not affect its stability, and it has a very good use effect.
