Description

Technical Field

[0001] The invention belongs to the technical field of laser cutting, in particular to a multi-angle laser cutting device. Background Art

[0002] Laser tube cutting machine is a kind of equipment that uses high-energy laser beam to accurately cut metal tubes. It uses the thermal effect and optical principle of laser to cut metal tubes, and has the advantages of high precision, high efficiency, flexibility and environmental protection. Laser tube cutting machine is widely used in cutting and processing various metal tubes, including fitness equipment manufacturing, automobile manufacturing, home furniture and other industries.

[0003] When cutting the pipe, the pipe will pass through the chuck, and the chuck will clamp the pipe. By controlling the rotation of the chuck, the pipe can be driven to rotate at multiple angles. During the multi-angle rotation of the pipe, the cutting head can be used to perform straight line cutting, curve cutting, hole cutting, groove cutting, and pipe cutting on the rotating pipe surface;

[0004] At present, when processing pipes, a feeding device is generally used to feed the pipes. When the pipes move to the chuck box position, the feeding mechanism drives the pipes to move inside the chuck. When the pipes move to the bottom of the cutting head, the chuck is used to clamp the pipes, and then the pipes can be cut.

[0005] Since the pipe itself has a certain length, when the pipe is clamped on the chuck, the center of gravity of the pipe is located behind the chuck, which will cause the pipe to slightly warp after clamping; at the same time, when cutting a rectangular groove on the pipe, the chuck will first slightly loosen the pipe, and then drive the pipe to move through the feeding mechanism. The moving pipe will pass through the chuck, so that the pipe will be fed while being cut by the cutting head. Since the moving pipe is not completely clamped by the chuck, the pipe will be cut in a warped state, which will affect the accuracy of the pipe after cutting. Summary of the invention

DETAILED DESCRIPTION

[0062] A cutting head 14 is installed at the bottom of the laser generator; a material unloading inclined plate 15 is installed in the load-bearing bed 1 below the cutting head 14;

[0063] A power assembly is installed on the right side of the chuck 13; the power assembly includes a swivel seat 2; the swivel seat 2 is installed above the load-bearing bed 1;

[0064] The top of the load-bearing bed 1 is provided with slide grooves 21 on both sides of the load-bearing bed 1; two sliders 22 are installed under the rotating seat 2, and the sliders 22 slide in the corresponding slide grooves 21 respectively;

[0065] Two first electric push rods 23 are installed on the end surface of the rotating seat 2 away from the chuck 13, and the other end of the first electric push rod 23 is installed in the chassis 11;

[0066] A turntable 24 is rotatably connected in the turntable 2; two sets of limit assemblies are installed on the side of the turntable 24 facing the chuck 13, and the two sets of limit assemblies are mirror-set with the center of the turntable 24 as the midline; the limit assemblies are used to limit the pipe 16 during cutting;

[0067] A mounting frame is installed on the side of the turntable 24 away from the chuck 13; a servo motor 25 is fixedly installed on the mounting frame, and the servo motor 25 is used to drive the turntable 24 to rotate;

[0068] A blanking assembly is installed at the bottom of the rotating seat 2, and the blanking assembly is used to blank the cut pipe 16;

[0069] In this embodiment, the two limit assemblies include an extension rod 3; two extension rods 3 are fixedly mounted on one end surface of the turntable 24 facing the chuck 13, and the two extension rods 3 are respectively arranged at the top and bottom positions of the center of the turntable 24;

[0070] The diameter of the extension rod 3 is smaller than the diameter of the pipe 16 to be cut;

[0071] The two extension rods 3 are fixedly mounted with a limit shaft 31 on one side facing the chuck 13, and both side end surfaces of the limit shaft 31 are spherical surfaces;

[0072] The axis of the upper limiting shaft 31 is collinear with the axis of the chuck 13; the lower limiting shaft 31 is located below the chuck box 12;

[0073] The diameter of the two limiting shafts 31 is the same as the inner diameter of the pipe 16 to be cut;

[0074] A circular ring 32 is installed on each of the two limiting shafts 31; a first limiting plate 33 is provided on the opposite side of each of the two circular rings 32; and the two first limiting plates 33 are fixedly installed on the adjacent circular rings 32;

[0075] The surfaces of the two first limiting plates 33 on one side away from the extension rod 3 are arc surfaces, and the diameter of the arc surfaces of the first limiting plates 33 is the same as the diameter of the limiting shaft 31;

[0076] The two first limiting plates 33 are bent toward the extension rod 3 on one side facing the chuck 13;

[0077] The blanking assembly includes a second electric push rod 26; the second electric push rod 26 is fixedly installed on the bottom of the rotating seat 2, and the second electric push rod 26 is located below the rotating disk 24; a push block 27 is fixedly installed on the side of the second electric push rod 26 facing the chuck 13;

[0078] Specifically, when cutting the pipe 16, the chuck 13 is first controlled to open, and then the first electric push rod 23 is controlled to extend. The extended first electric push rod 23 will push the turntable 2 to move, and the slider 22 installed under the turntable 2 will slide in the slide groove 21. At the same time, the turntable 2 will drive the turntable 24 and the two limit assemblies on the turntable 24 to move toward the side of the chuck 13. During the movement of the two limit assemblies, the limit shaft 31 on the upper limit assembly will gradually move into the inside of the chuck 13, and the limit shaft 31 on the lower limit assembly will move to the position below the chuck box 12. At the same time, the turntable 24, the extension rod 3 and the first limit plate 33 will move with the turntable 2. When the upper limit shaft 31 moves to the inside of the chuck 13, the first limit plate 33 and The middle part of the cutting head 14 corresponds, and the ring 32 is staggered with the cutting head 14, and then the first electric push rod 23 is controlled to stop extending, and then the feeding mechanism is controlled to work, and the feeding mechanism will push the pipe 16 from the left side of the chuck 13 into the chuck 13. When the pipe 16 enters the chuck 13, the pipe 16 will contact the limiting shaft 31. Since the end faces on both sides of the limiting shaft 31 are spherical, and since the diameter of the limiting shaft 31 is the same as the inner ring diameter of the pipe 16, the limiting shaft 31 will gradually insert into the pipe 16. When the limiting shaft 31 is inserted into the pipe 16, the limiting shaft 31 can guide the moving direction of the pipe 16 and limit the pipe 16 at the same time, so that the axis of the pipe 16 is in line with the axis of the limiting shaft 31, and then continue to push the pipe 16 to move;

[0079] More specifically, as the pipe 16 continues to move, the side of the first limiting plate 33 that is bent toward the extension rod 3 will contact the pipe 16. Since the diameter of the arc surface of the first limiting plate 33 is the same as the diameter of the limiting shaft 31, the first limiting plate 33 will gradually be inserted into the pipe 16. The first limiting plate 33 inserted into the pipe 16 can limit the pipe 16 located below the cutting head 14, and then the pipe 16 can be cut.

[0080] Furthermore, when cutting the tube 16, the cutting head 14 is controlled to move downward and emit a laser to cut the tube 16. At the same time, the chuck 13 drives the tube 16 to rotate, and the rotating tube 16 gradually passes through the cutting head 14, thereby cutting the tube 16. If it is necessary to cut a rectangular groove on the surface of the tube 16, the feeding mechanism will push the tube 16 to move, so that the tube 16 is fed and cut at the same time. In the above process, no matter how the tube 16 is cut, due to the existence of the limit shaft 31, the limit shaft 31 can limit the feeding tube 16, thereby ensuring that it is fed and cut at the same time. The pipe 16 is in a horizontal state, and the pipe 16 being cut can be kept in a horizontal state while rotating. At the same time, the first limiting plate 33 can limit the pipe 16 below the cutting head 14, so as to further improve the limiting effect of the pipe 16, thereby avoiding the pipe 16 from warping during cutting, thereby affecting the accuracy of the pipe 16 after cutting; at the same time, since the limiting shaft 31 extends into the chuck 13, when the chuck 13 clamps the pipe 16, the limiting shaft 31 can support the inside of the pipe 16, thereby avoiding the pipe 16 with a thin wall thickness from being easily deformed when being clamped;

[0081] It should be noted that when the cutting head 14 cuts the tube 16, it focuses a high-energy laser beam on the surface of the tube 16, and cuts the tube 16 through the interaction between the laser and the tube 16. In this process, the laser beam mainly acts on the outer surface of the tube 16, and melts or vaporizes the tube 16 through high heat energy, thereby achieving the purpose of cutting. Since the energy of the laser beam is concentrated on a specific focus, the laser beam will not penetrate the inside of the tube 16, so the extension rod 3 located in the tube 16 will not be affected by the laser and will not be cut by the laser. At the same time, since the ring 32 is staggered with the cutting head 14, the ring 32 will not be cut by the laser either.

[0082] Furthermore, when the cutting of the pipe 16 is completed and the cutting head 14 cuts the pipe 16, the cut pipe 16 will be sleeved on the extension rod 3, and then the first electric push rod 23 will be controlled to shrink, thereby driving the swivel seat 2, the turntable 24, the extension rod 3, the first limit plate 33 and the limit shaft 31 to gradually restore to the initial state. During the recovery of the extension rod 3, the cut pipe 16 will be driven to move. When the extension rod 3 moves to the initial position, the servo motor 25 is controlled to rotate 180 degrees, thereby driving the two limit assemblies on the turntable 24 to rotate 180 degrees. When the two limit assemblies are rotated, the upper limit assemblies originally located at the upper limit plate 33 will be moved. The limit assembly is rotated downward, and the limit assembly originally located at the bottom is rotated upward. At the same time, the cut pipe 16 is also rotated downward, and then the second electric push rod 26 is controlled to extend, and the second electric push rod 26 will push the push block 27 to move. The moving push block 27 can push down the cut pipe 16 on the extension rod 3, and then the pipe 16 will roll down from the unloading inclined plate 15, and then the second electric push rod 26 is controlled to restore to its original state, and the first electric push rod 23 is controlled to extend, and the extended first electric push rod 23 will push the limit shaft 31 in the upper limit assembly to be inserted into the chuck 13 again, so that the pipe 16 can continue to be cut.

[0083] Embodiment 2: The two first limiting plates 33 are fixedly connected to a rectangular rod 34 on one side of the end surface facing the rotating disk 24, and the other side of the rectangular rod 34 passes through the rotating disk 24 and is slidably connected to the rotating disk 24;

[0084] The outer surfaces of the two rectangular rods 34 are sleeved with springs, and the springs are located between the rotating disk 24 and the first limiting plate 33;

[0085] A second limiting plate 4 is provided on the opposite side of the two first limiting plates 33; the surface of the two second limiting plates 4 on one side close to the extension rod 3 is an arc surface, and the diameter of the arc surface of the second limiting plate 4 is the same as the outer diameter of the tube 16;

[0086] The two second limit plates 4 are bent toward the side away from the extension rod 3 on the side facing the chuck 13; the distance between the first limit plate 33 and the second limit plate 4 is the same as the thickness of the tube 16;

[0087] The two second limit plates 4 are both fixedly mounted with mounting blocks 41 on one side facing the rotating disk 24, and the mounting blocks 41 are both extended to between the rectangular rod 34 and the extension rod 3;

[0088] The two mounting blocks 41 are provided with concave grooves 42, and the rectangular rod 34 slides on the rectangular rod 34 through the concave grooves 42; the rectangular rod 34 is a reinforcing rod;

[0089] In this embodiment, a ceramic tube 35 is fixedly sleeved on the surface of the extension rod 3, and the ceramic tube 35 surrounds the extension rod 3; the ring 32 is installed on the ceramic tube 35;

[0090] In this embodiment, the arc surfaces of the first limiting plate 33 and the second limiting plate 4 are both smooth surfaces;

[0091] Specifically, when the first limit plate 33 is inserted into the tube 16, the tube 16 will be inserted between the first limit plate 33 and the second limit plate 4. As the tube 16 continues to move, the end of the tube 16 will contact the mounting block 41. At this time, the mounting plate 43 and the second limit plate 4 will be blocked by the tube 16. Therefore, during the movement of the tube 16, the mounting block 41 will be pushed to slide along the rectangular rod 34 toward the position of the turntable 24 and compress the spring sleeved on the rectangular rod 34. At the same time, the mounting block 41 will drive the second limit plate 4 to move, and the second limit plate 4 will gradually stagger with the first limit plate 33. When the tube 16 stops moving, the mounting block 41 and the second limit plate 4 will also stop moving.

[0092] More specifically, when the tube 16 is cut, if the chuck 13 drives the tube 16 to rotate, the tube 16 is located between the first limiting plate 33 and the second limiting plate 4, so the tube 16 will rotate between the first limiting plate 33 and the second limiting plate 4, so that the tube 16 can be further limited by the cooperation of the first limiting plate 33 and the second limiting plate 4, so as to avoid the tube 16 from tilting and jumping when rotating. Since the rectangular rod 34 is a reinforcing rod, the stability of the extension rod 3 can be indirectly improved to avoid the extension rod 3 from being deformed under the action of the tube 16.

[0093] Furthermore, since the arc surfaces of the first limiting plate 33 and the second limiting plate 4 are both smooth surfaces, the friction between the tube 16 and the first limiting plate 33 and the second limiting plate 4 can be reduced during the rotation of the tube 16;

[0094] Furthermore, since the ceramic tube 35 is sleeved on the extension rod 3, the extension rod 3 can be further protected because the laser has little impact on the ceramic material and is not easily damaged.

[0095] Embodiment 3: The limiting shaft 31 includes an inner shaft 311 and an outer shaft 312; the outer shaft 312 is hollow, and the outer shaft 312 is sleeved on the inner shaft 311;

[0096] The inner shaft 311 is provided with evenly arranged thread grooves 313; the outer shaft 312 is provided with evenly arranged countersunk holes 314; the countersunk holes 314 are provided with hexagon socket bolts, and the hexagon socket bolts are engaged with the thread grooves 313 on the inner shaft 311, so as to fix the outer shaft 312 on the inner shaft 311;

[0097] In this embodiment, a mounting plate 43 is welded to one side of the two first limiting plates 33 close to the extension rod 3, and a through hole is opened on the mounting plate 43;

[0098] The two circular rings 32 are also provided with through holes on one side close to the mounting plate 43, and the through holes on the mounting plate 43 coincide with the through holes on the circular rings 32, and the circular rings 32 and the mounting plate 43 are locked and fixed by bolts and nuts;

[0099] Specifically, when it is necessary to cut pipes 16 of different diameters, the staff removes the hexagon socket bolts in the countersunk hole 314 with a hexagon socket wrench, and then removes the outer shaft 312 from the inner shaft 311, and then selects the outer shaft 312 that matches the diameter of the pipe 16 to be cut. After the outer shaft 312 is selected, the outer shaft 312 is then sleeved on the inner shaft 311, and then the inner shaft 311 and the outer shaft 312 are fixed with the hexagon socket bolts.

[0100] More specifically, the nuts of the locking ring 32 and the mounting plate 43 are then unscrewed with a wrench, and the bolts are then pulled out from the through holes on the mounting plate 43 and the ring 32, and the first limiting plate 33 is then pulled to the left, and the rectangular rod 34 connected to the first limiting plate 33 is gradually pulled out from the turntable 24, and then the first limiting plate 33 and the second limiting plate 4 that are adapted thereto are selected according to the diameter of the pipe 16 to be cut. After the selection is completed, the rectangular rod 34 is first passed through the turntable 24, and then the through holes on the mounting plate 43 are aligned with the through holes on the ring 32, and then the ring 32 and the mounting plate 43 are locked and fixed with bolts and nuts;

[0101] By replacing the outer shaft 312 and the first limit plate 33 and the second limit plate 4 of different specifications, pipes 16 of different diameters can be adapted, so that pipes 16 of different diameters can be limited and supported. Therefore, when supporting pipes 16 of different diameters, the pipes 16 can be protected by the limit assembly to avoid deformation or warping of the pipes 16, thereby improving the practicality of the limit assembly.

[0102] Embodiment 4: The end surface of the ring 32 close to the rotating disk 24 is fixedly connected with evenly arranged threaded rods 36, and the threaded rods 36 all pass through the rotating disk 24 and are slidably connected to the rotating disk 24;

[0103] The two sides of the turntable 24 are threadedly engaged with locking nuts on the threaded rods 36, and the locking nuts are used to lock the threaded rods 36 on the turntable 24; the ring 32 slides on the ceramic tube 35;

[0104] Specifically, when the position of the ring 32 needs to be adjusted, the staff can loosen the locking nut that locks the threaded rod 36. When the locking nut is loosened, the ring 32 can be pushed to move on the ceramic tube 35. During the movement of the ring 32, the ring 32 will drive the threaded rod 36 and the rectangular rod 34 to move. When the ring 32 moves to a suitable position, the locking nut is rotated and the threaded rod 36 is locked on the turntable 24 using the locking nut.

[0105] More specifically, due to the existence of the threaded rod 36, the threaded rod 36 can support the ring 32 and the extension rod 3, thereby further improving the stability of the extension rod 3 and preventing the extension rod 3 from being deformed under the action of the steel pipe.
