Description

Technical Field

[0001] The invention belongs to the technical field of cutting devices, and in particular relates to a plasma cutting device for a marine generator set. Background Art

[0002] The plasma cutting device for marine generator sets utilizes plasma cutting technology, using the heat of a high-temperature plasma arc to partially melt the metal at the cutout of the marine generator metal plate. The momentum of the high-speed plasma then drives the molten metal out to form the cutout. Combined with different working gases, the device can cut a variety of metals that are difficult to cut with oxygen, and is particularly effective for non-ferrous metals. When cutting thin metals, plasma cutting offers fast speeds, smooth cut surfaces, minimal thermal deformation, and a small heat-affected zone.

[0008] Preferably, two sliding sleeves are fixedly installed on the lower part of the connecting frame, and sliding rods are inserted into the interior of the two sliding sleeves, and one end of the two sliding rods is fixedly connected to one side of the workbench.

[0012] Preferably, the two bent rods are fixedly installed with support arms at one end away from the insertion rod, and support bars are fixedly installed between the two ends of the two support arms. Four pressure rods are fixedly installed on the lower part of the two support bars, and the bottom ends of the eight pressure rods are fixedly connected to eight clamping heads.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) During operation, the operator places the metal plate of the marine generator set into the placement slot, and then starts the servo motor to drive the driving sprocket to rotate. When the driving sprocket rotates, the driven sprocket is driven to rotate along the rotating shaft through the chain. When the driven sprocket and the driving sprocket rotate, the threaded rod is driven to rotate along the positioning seat. When the two threaded rods rotate, the connecting beam is driven to move through the two threaded sleeves. The movement of the connecting beam drives the pushing bar to move through the two fixed rods and the installation bar. When the pushing bar moves, the limit sleeve is driven to slide on the surface of the limit rod, thereby increasing the stability of the pushing bar when it moves.

[0015] When the pushing bar moves, it quickly squeezes the transmission beam downward through the inclined slot. When the transmission beam moves downward, it drives the two insertion rods to move downward along the inside of the two slots, and at the same time drives the two bending rods to move downward. When the two bending rods move downward, they squeeze the two springs to contract. When the two bending rods move downward, they drive the two support bars downward through the two support arms. When the two support bars move downward, the eight pressing heads are driven downward through the eight pressure rods to press and fix the metal plates. When the connecting beam moves, it drives the three plasma cutting machine bodies to move through the connecting frame. When the connecting beam moves, it drives the two sliding sleeves to slide along the surfaces of the two sliding rods, thereby increasing the stability of the connecting frame and the three plasma cutting machine bodies when they move.

[0016] (2) Since the front end of the pushing bar is inclined and then becomes straight, the pushing bar can push the eight pressing heads to press the metal plate while continuing to move, thereby ensuring the stability of the metal plate pressing while allowing the three plasma cutting machine bodies to move and cut the metal plate; at the same time, since the three plasma cutting machine bodies can cut the metal plate into four parts, the eight pressing heads can simultaneously press the two ends of the four parts to ensure the stability of the metal plate during the cutting process;

[0017] (3) The cutting device adopts a compression fixation method to effectively ensure the stability of metal cutting. The gap generated during cutting will not affect its stability, and it has a very good use effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] Embodiment 1, by Figures 1 to 7 The present invention includes a workbench 1, wherein support legs 2 are fixedly installed at the four corners of the bottom of the workbench 1, a pad 3 is fixedly installed between the bottoms of the two support legs 2 on the same side, a support frame 4 is fixedly installed between one end of the upper side of the pad 3, and a servo motor 8 is fixedly installed at one end of one side of the support frame 4. A placement slot 6 is provided in the middle of the top of the workbench 1, and three cutting slots 7 are provided inside the placement slot 6. Eight clamping heads 5 are provided above the placement slot 6, and three plasma cutting machine bodies 9 are provided on one side above the workbench 1. The output end of the servo motor 8 is provided with a transmission assembly, which is connected to the eight clamping heads 5 and the three plasma cutting machine bodies 9. When the servo motor 8 is running, power is output to the eight clamping heads 5 and the three plasma cutting machine bodies 9 through the transmission assembly, so that the eight clamping heads 5 move down to clamp the metal plate of the marine generator, and the three plasma cutting machine bodies 9 synchronously cut the metal plate of the marine generator.

[0030] During work, the operator places the metal plate of the marine generator set into the placement slot 6, and then starts the servo motor 8 to drive the transmission assembly to operate. When the transmission assembly is operating, it drives the eight clamping heads 5 to move down and clamp and fix the metal plate. Then the transmission assembly will also move the three plasma cutting machine bodies 9 to cut the metal plate of the marine generator set. Since the three plasma cutting machine bodies 9 can cut the metal plate into four parts, and the eight clamping heads 5 can simultaneously clamp the two ends of the four parts to ensure the stability of the metal plate during the cutting process; the cutting device adopts a clamping and fixing method to effectively ensure the stability of the metal during cutting, and the gaps generated during cutting will not affect its stability, and it has a very good use effect.

[0031] In the second embodiment, based on the first embodiment, the transmission assembly includes a driving sprocket 12 and a rotating shaft 11. The driving sprocket 12 is fixedly mounted on the output end of the servo motor 8. The rotating shaft 11 is rotatably mounted on the other end of the support frame 4. A driven sprocket 13 is fixedly mounted on one end of the rotating shaft 11. A chain 14 is meshed and connected between the driving sprocket 12 and the driven sprocket 13.

[0032] A threaded rod 15 is fixedly installed on one side of the driven sprocket 13 and the driving sprocket 12, and a positioning seat 30 is rotatably installed on one end of the threaded rod 15. The tops of the two positioning seats 30 are fixedly connected to the bottom of the workbench 1, and the surfaces of the two threaded rods 15 are threadedly connected to threaded sleeves 16. A connecting beam 17 is fixedly installed between the threaded sleeves 16, and a connecting frame 18 is fixedly installed in the middle of the top of the connecting beam 17. One side of the connecting frame 18 is fixedly connected to the three plasma cutting machine bodies 9.

[0033] The operator starts the servo motor 8 to drive the driving sprocket 12 to rotate. When the driving sprocket 12 rotates, the driven sprocket 13 is driven to rotate along the rotating shaft 11 through the chain 14. When the driven sprocket 13 and the driving sprocket 12 rotate, they both drive the threaded rod 15 to rotate along the positioning seat 30. When the two threaded rods 15 rotate, the connecting beam 17 is driven to move through the two threaded sleeves 16. When the connecting beam 17 moves, the three plasma cutting machine bodies 9 are driven to move through the connecting frame 18. When the connecting beam 17 moves, the two sliding sleeves 19 are driven to slide along the surface of the two sliding rods 20, thereby increasing the stability of the connecting frame 18 and the three plasma cutting machine bodies 9 when they move.

[0034] Embodiment 3, on the basis of embodiment 2, two sliding sleeves 19 are fixedly installed at the lower part of the connecting frame 18, and sliding rods 20 are inserted inside the two sliding sleeves 19, and one end of the two sliding rods 20 is fixedly connected to one side of the workbench 1; the bottom of the connecting beam 17 is fixedly installed with a mounting bar 22 through two fixing rods 21, and a pushing bar 23 is fixedly installed in the middle of one side of the mounting bar 22, and the inclined surface of one end of the pushing bar 23 is tightly attached to the transmission beam 24, and an inclined groove 25 is opened in the middle of the upper part of the transmission beam 24, and the inclined groove 25 is adapted to the inclined surface of one end of the pushing bar 23; a limiting sleeve 26 is fixedly installed on the top of one end of the pushing bar 23, and a limiting rod 27 is inserted inside the limiting sleeve 26, and a fixing plate 28 and a fixing frame 29 are fixedly installed at both ends of the limiting rod 27, and the top of the fixing plate 28 is fixedly connected to the bottom of the workbench 1, and one end of the fixing frame 29 is fixedly connected to the other side of the workbench 1;

[0035] The connecting beam 17 moves through the two fixing rods 21 and the mounting bar 22 to drive the pushing bar 23 to move. When the pushing bar 23 moves, it drives the limiting sleeve 26 to slide on the surface of the limiting rod 27, thereby increasing the stability of the pushing bar 23 when it moves. When the pushing bar 23 moves, it quickly squeezes the transmission beam 24 downward through the inclined groove 25.

[0036] Both ends of the upper part of the transmission beam 24 are fixedly installed with an insertion rod 31, and both ends of the upper part of the workbench 1 are provided with a slot 32. The two insertion rods 31 are inserted into the inside of the two slots 32. The surfaces of the two insertion rods 31 are sleeved with a spring 33. The tops of the two insertion rods 31 are fixedly installed with a bent rod 34. The two ends of the two springs 33 are fixedly connected to the bent rod 34 and the top of the workbench 1 respectively.

[0037] A support arm 10 is fixedly installed at one end of the two bent rods 34 away from the insertion rod 31, and a support bar 35 is fixedly installed between the two ends of the two support arms 10. Four pressure rods 36 are fixedly installed at the lower part of the two support bars 35, and the bottom ends of the eight pressure rods 36 are fixedly connected to the eight clamping heads 5.

[0038] When the transmission beam 24 moves downward, it drives the two insertion rods 31 to move downward along the inside of the two slots 32, and at the same time drives the two bent rods 34 to move downward. When the two bent rods 34 move downward, they squeeze the two springs 33 to contract. When the two bent rods 34 move downward, they drive the two support bars 35 to move downward through the two support arms 10. When the two support bars 35 move downward, they drive the eight pressing heads 5 to move downward through the eight pressing rods 36 to press and fix the metal plate.

[0039] Since the front end of the pushing bar 23 is inclined and then becomes straight, the pushing bar 23 can push the eight clamping heads 5 to press the metal plate while continuing to move, thereby ensuring the stability of the metal plate clamping while enabling the three plasma cutting machine bodies 9 to move and cut the metal plate; at the same time, since the three plasma cutting machine bodies 9 can cut the metal plate into four parts, the eight clamping heads 5 can simultaneously clamp the two ends of the four parts to ensure the stability of the metal plate during the cutting process.
