Description

Technical Field

[0001] The present invention relates to the technical field of intelligent cutting equipment, and in particular to a fiber laser cutting machine for processing steel structural parts. Background Art

[0002] A fiber laser cutting machine uses a fiber laser generator as its light source. Fiber lasers are a new type of internationally developed technology that outputs a high-energy-density laser beam that focuses on the workpiece surface, instantly melting and vaporizing the area illuminated by the ultra-fine focal spot, enabling automatic cutting. They are commonly used for cutting metal steel components.

[0003] When cutting steel components with existing technology, it is first necessary to place the steel component in the cutting position and fix it with a clamp, then adjust the position of the cutting device, set the cutting route and cut. This process requires the use of precise instruments. When dealing with steel components of different sizes (including different lengths and widths), it is necessary to repeatedly adjust the cutting path and cutting position, which is relatively inconvenient. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a fiber laser cutting machine for processing steel structures to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure. The limiting components on the four sides of the cutting plate can simultaneously clamp and limit the side edges of the steel structure. Two of the groups are connected to the cutting frame, corresponding to the route where the steel structure needs to be cut, and the other two groups are squeezed and fixed on the top by a pressure plate. The laser cutting device cuts the steel structure with the guidance of the cutting frame and the traction of the winding seat, and the cutting path is determined according to the length of the connecting rope, and there will be no problems of insufficient cutting distance or the cutting device moving too far.

[0006] Furthermore, side slide rails are provided on both sides of the cutting table, vertical beams are slidably installed on the side slide rails, the cross beams are slidably connected to the inner grooves of the vertical beams, a first electric push rod is fixed on the top of the vertical beam, and the extended end of the first electric push rod is fixedly connected to the cross beam.

[0007] Furthermore, a cylinder is fixed on the top of the slide, and the extended end of the cylinder is fixedly connected to the laser cutting device.

[0008] Furthermore, sliding grooves are opened at equal intervals on the surface of the cutting table, and convex strips are fixed at positions corresponding to the sliding grooves on the bottom of the cutting plate, and the convex strips are slidably inserted into the sliding grooves.

[0009] Furthermore, the limiting assembly also includes a movable groove, and movable grooves are opened on the four sides of the cutting plate, and a translation screw is rotatably installed inside the movable groove through a bearing, a slide is threadedly sleeved on the surface of the translation screw, and a mounting frame is fixed on the top of the slide.

[0010] Furthermore, a bidirectional screw is rotatably installed inside the mounting frame through a bearing, and moving blocks are threadedly sleeved on both ends of the bidirectional screw. The moving block is rotatably connected to a connecting rod through a rotating shaft toward the side of the vertical plate, and the other end of the connecting rod is rotatably connected to the back side of the vertical plate through a rotating shaft.

[0011] Furthermore, a gear ring is rotatably installed on the periphery of the disc, and the gear ring is fixedly connected to the rotating ring of the pressure plate. A gear is meshed with one side of the gear ring, and a driving motor is fixed on the top of the gear corresponding to the disc, and the output end of the driving motor is fixedly connected to the gear.

[0012] Furthermore, a second electric push rod is fixed to the top of the front end of the vertical plate, and the extended end of the second electric push rod slides through the disc and is fixedly connected to the connecting frame.

[0013] Furthermore, electric suction cups are fixedly installed on the top and bottom of both ends of the connecting frame, and the electric suction cups are adsorbed on the surface of the disc or cutting frame under the push of the second electric push rod.

[0014] Furthermore, a screw column is fixed to the movable end of the connecting rope, a screw hole is provided on the slide corresponding to the position where the connecting rope is locked and installed, and the screw column is threadedly inserted into the screw hole.

[0015] Beneficial effects of the present invention:

[0016] 1. The present invention drives the gear to rotate and engage with the gear ring through a driving motor, driving the pressure plate to rotate to the inner side of the vertical plate, that is, the upper end of the steel structure. Then, the electric suction cups of the connecting frames on the left and right sides are placed at the bottom of the disc through the telescopic adjustment of the second electric push rod to contact and adsorb and connect. Then, the second electric push rod drives the pressure plate to press on the top surface of both sides of the steel structure, and combines with the vertical plate to limit and clamp the left and right sides.

[0017] 2. The present invention rotates the bidirectional screw, the moving block engages with the bidirectional screw, and the connecting rod pushes the vertical plate to move until it contacts the steel structure. At this time, the vertical plates at the front and rear ends slide along the groove of the cutting frame, and the connecting ropes of the front and rear end winding seats are connected to the screw holes of the slide through the screw columns, and then the translation screws inside the front and rear end moving grooves are driven to rotate separately, and the slide slides along the moving groove to adjust the lateral position of the vertical plate and the cutting frame. Because of the connection between the slide and the connecting rope, the crossbeam now passes through the vertical beam along the side slide rail, keeping the laser cutting device and the cutting frame path in a straight line. The cutting frame squeezes and contacts the cutting sides of the top of the steel structure to avoid deformation caused by high temperature.

[0018] 3. The present invention uses a winding laser cutting device to synchronously slide along the crossbeam through the winding of the connecting rope. The movement of the laser cutting device is controlled by the winding seats at both ends of the cutting route, one for unwinding and the other for winding. Because the length of the connecting rope released by the winding seats at both ends is certain after adjusting the position, the servo motor controller is used to wind the fixed length. When the length is reached, the winding is stopped immediately, and the slide and the laser cutting device will also stop moving, which can avoid the problem of excessive movement of the laser cutting device or insufficient cutting.

[0019] 4. The cutting plate of the present invention is connected to the cutting table in a sliding manner through the convex strips, and the cutting plate can be pulled out from the cutting table by pulling, which is convenient for placing or removing the cut steel components. During this process, the first electric push rod controls the horizontal beam to slide and rise along the groove of the vertical beam to avoid movement interference with the limit assembly on the cutting plate.

[0020] 5. Compared with the prior art, the limiting components on the four sides of the cutting plate of the present invention can simultaneously clamp and limit the side edges of the steel structure. Two of the limiting components are connected to the cutting frame, corresponding to the route of the steel structure that needs to be cut, and the other two groups are squeezed and fixed on the top through the pressure plate. The laser cutting device cuts the steel structure with the guidance of the cutting frame and the traction of the winding seat, and the cutting path is determined by the length of the connecting rope, so there will be no problems of insufficient cutting distance or the cutting device moving too far.

[0031] In this embodiment, side slide rails 11 are provided on both sides of the cutting table 1, and vertical beams 12 are slidably installed on the side slide rails 11.

[0032] In this embodiment, the surface of the cutting table 1 is provided with sliding grooves 18 at equal intervals, and a convex strip 21 is fixed at a position corresponding to the sliding groove 18 on the bottom of the cutting plate 2, and the convex strip 21 is slidably inserted into the inside of the sliding groove 18. The cutting plate 2 is slidably connected to the cutting table 1 through the convex strip 21, and the cutting plate 2 can be pulled out from the cutting table 1 by pulling, which is convenient for placing or removing the cut steel member 3. In this process, the first electric push rod 17 controls the horizontal beam 13 to slide and rise along the groove of the vertical beam 12, so as to avoid causing movement interference to the limit component 4 on the cutting plate 2.

[0033] In this embodiment, the limiting assembly 4 also includes a moving groove 48, and the four sides of the cutting plate 2 are provided with a moving groove 48, and a translation screw 46 is rotatably installed inside the moving groove 48 through a bearing, and a slide 47 is threadedly sleeved on the surface of the translation screw 46, and a mounting bracket 41 is fixed on the top of the slide 47, and a bidirectional screw 42 is rotatably installed inside the mounting bracket 41 through a bearing, and the two ends of the bidirectional screw 42 are threadedly sleeved with a moving block 43, and the moving block 43 is rotatably connected to the connecting rod 44 toward the side of the vertical plate 45 through a rotating shaft, and the other end of the connecting rod 44 is rotatably connected to the back of the vertical plate 45 through a rotating shaft, and the outer periphery of the disc 411 is rotatably installed with a gear ring 412, and the gear ring 412 is fixed to the rotating ring of the pressure plate 415 The gear ring 412 is connected with a gear 414 on one side, and a driving motor 413 is fixed to the top of the gear 414 corresponding to the disc 411, and the output end of the driving motor 413 is fixedly connected to the gear 414. A second electric push rod 49 is fixed to the top of the front end of the vertical plate 45, and the extended end of the second electric push rod 49 slides through the disc 411 and is fixedly connected to the connecting frame 416. Electric suction cups 417 are fixedly installed on the top and bottom of both ends of the connecting frame 416. The electric suction cups 417 are adsorbed on the surface of the disc 411 or the cutting frame 23 under the push of the second electric push rod 49. A screw column 419 is fixed to the movable end of the connecting rope 418, and the slide 14 is opened at the position where the connecting rope 418 is locked and installed. There are screw holes 420, and the screw columns 419 are threadedly inserted into the screw holes 420. In this solution, the cutting direction of the steel structure is limited to horizontal or vertical cutting. According to the two cutting directions, the corresponding cutting frame 23 is selected. Taking the figure in this solution as an example, the front and rear cutting directions are selected to cut the steel structure. First, the connecting frame 416 on the front and rear end vertical plates 45 is pushed to contact the cutting frame 23 by the second electric push rod 49. The two electric suction cups 417 at the bottom of the connecting frame 416 adsorb the cutting frame 23 and lift the cutting frame 23 from the storage groove 22 to facilitate the placement of the steel structure on the cutting plate 2. The pressing plate 415 on the vertical plate 45 for connecting the cutting frame 23 is rotated to the back. After the steel structure 3 is placed, the vertical plates 45 on the left and right sides are pressed. The disc 411 drives the gear 414 to rotate and mesh with the gear ring 412 through the driving motor 413, driving the pressure plate 415 to rotate to the inside of the vertical plate 45, that is, the upper end of the steel component 3, and then the electric suction cups 417 of the left and right connecting frames 416 are placed on the bottom of the disc 411 through the telescopic adjustment of the second electric push rod 49 to contact and be adsorbed and connected. The second electric push rod 49 then drives the pressure plate 415 to press on the top surface of both sides of the steel component 3, and combines with the vertical plate 45 to limit and clamp the left and right sides. The front and rear and left and right vertical plates 45 are all rotated by the two-way screw rod 42, the moving block 43 meshes with the two-way screw rod 42, and the connecting rod 44 pushes the vertical plate 45 to move until it contacts the steel component 3. At this time, the vertical plates 45 at the front and rear ends slide along the grooves of the cutting frame 23.The connecting rope 418 of the front and rear end winding seat 410 is connected to the screw hole 420 of the slide 14 through the screw column 419, and then the translation screw rod 46 inside the front and rear end moving groove 48 is driven separately to rotate, and the slide plate 47 slides along the moving groove 48 to adjust the horizontal position of the vertical plate 45 and the cutting frame 23. Because the slide 14 is connected to the connecting rope 418, the crossbeam 13 now moves along the side slide rail 11 through the vertical beam 12, keeping the path of the laser cutting device 16 and the cutting frame 23 in a straight line. The cutting frame 23 squeezes and contacts the cutting sides of the top of the steel member 3 to avoid deformation caused by high temperature. When cutting in the left and right directions is required, the principle Similarly, the left and right vertical plates 45 are switched to connect with the cutting frame 23 to guide the laser cutting device 16. The laser cutting device 16 slides synchronously along the crossbeam 13 with the winding rope 418. The movement of the laser cutting device 16 is controlled by the winding seats 410 at both ends of the cutting path, one unwinding and the other rewinding. Because the connecting rope 418 released by the winding seats 410 at both ends is a certain length after adjusting the position, the servo motor controller is used to rewind the fixed length. When the length is reached, the rewinding stops immediately, and the carriage 14 and the laser cutting device 16 also stop moving. This can avoid the problem of excessive movement of the laser cutting device 16 or insufficient cutting.

[0034] When using the device, place the steel member 3 on the cutting plate 2, and clamp the four sides of the steel member 3 through the limiting assembly 4. According to the direction of cutting required, connect the vertical plate 45 in the corresponding direction with the cutting frame 23, and cover the cutting frame 23 on the upper end of the steel member 3 to guide the laser cutting device 16. The winding seat 410 on the top of the vertical plate 45 pulls the laser cutting device 16 to make it cut the steel member 3 in a straight line. Select the front and rear cutting directions to cut the steel structure. First, the connecting frame 416 on the front and rear end vertical plates 45 is pushed by the second electric push rod 49 to contact the cutting frame 23. The two electric suction cups 417 at the bottom of the connecting frame 416 adsorb the cutting frame 23 and lift the cutting frame 23 from the storage slot 22 to facilitate the steel structure. After the steel member 3 is placed on the cutting plate 2, the pressure plate 415 on the vertical plate 45 for connecting the cutting frame 23 is rotated to the back. After the steel member 3 is placed, the disc 411 on the left and right vertical plates 45 drives the gear 414 to rotate and mesh with the gear ring 412 through the driving motor 413, driving the pressure plate 415 to rotate to the inner side of the vertical plate 45, that is, the upper end of the steel member 3. Then, the electric suction cup 417 of the left and right connecting frame 416 is placed on the bottom of the disc 411 through the telescopic adjustment of the second electric push rod 49 to contact and adsorb and connect. Then, the second electric push rod 49 drives the pressure plate 415 to press on the top surface of both sides of the steel member 3, and combines with the vertical plate 45 to limit and clamp the left and right sides. The front and rear and left and right vertical plates 45 are all rotated by the bidirectional screw rod 42, and the moving block 43 and the double The connecting rod 44 engages with the screw rod 42, and the connecting rod 44 pushes the vertical plate 45 to move until it contacts the steel member 3. At this time, the vertical plates 45 at the front and rear ends slide along the groove of the cutting frame 23, and the connecting ropes 418 of the front and rear end winding seats 410 are connected to the screw holes 420 of the slide 14 through the screw columns 419. Then, the translation screw rods 46 inside the front and rear end moving grooves 48 are driven to rotate separately, and the slide plate 47 slides along the moving groove 48 to adjust the lateral position of the vertical plate 45 and the cutting frame 23. Because the slide 14 is connected to the connecting rope 418, the crossbeam 13 now moves along the side slide rail 11 through the vertical beam 12, keeping the laser cutting device 16 and the path of the cutting frame 23 in a straight line. The cutting frame 23 squeezes and contacts the cutting sides of the top of the steel member 3 to avoid deformation caused by high temperature. When cutting in the left and right directions is required, the same principle is used. The left and right vertical plates 45 are switched to connect with the cutting frame 23 to guide the laser cutting device 16. The winding laser cutting device 16 of the connecting rope 418 slides synchronously along the crossbeam 13. The movement of the laser cutting device 16 is controlled by the winding seats 410 at both ends of the cutting route, one unwinding and the other winding. Because the connecting rope 418 released by the winding seats 410 at both ends is of a certain length after adjusting the position, the servo motor controller is used to wind the fixed length. When the length is reached, the winding is stopped immediately, and the slide 14 and the laser cutting device 16 will also stop moving, which can avoid the problem of excessive movement or insufficient cutting of the laser cutting device 16. The cutting plate 2 is connected to the cutting table 1 through the convex strip 21.The cutting plate 2 can be pulled out from the cutting table 1 to facilitate the placement or removal of the cut steel member 3. During this process, the first electric push rod 17 controls the horizontal beam 13 to slide and rise along the groove of the vertical beam 12 to avoid interference with the movement of the limit assembly 4 on the cutting plate 2.

At this time, the vertical plates (45) at the front and rear ends slide along the groove of the cutting frame (23), and then the translation screw rods (46) inside the front and rear end moving grooves (48) are driven to rotate separately. The slide plate (47) slides along the moving groove (48) to adjust the horizontal position of the vertical plate (45) and the cutting frame (23). Because the slide (14) is connected to the connecting rope (418), the crossbeam (13) now moves along the side slide rail (11) through the vertical beam (12) to keep the laser The cutting device (16) corresponds to the path of the cutting frame (23) in a straight line. The cutting frame (23) squeezes and contacts the cutting sides of the top of the steel member (3). The left and right vertical plates (45) are switched to connect with the cutting frame (23) to guide the laser cutting device (16). The laser cutting device (16) of the winding connecting rope (418) slides synchronously along the crossbeam (13). The movement of the laser cutting device (16) is controlled by the winding seats (410) at both ends of the cutting path. Because the length of the connecting rope (418) released by the winding seats (410) at both ends after adjusting the position is constant.
