Description

Technical Field

[0001] The utility model relates to the field of laser cutting machines, in particular to a cantilever double-beam three-dimensional five-axis laser cutting machine. Background Art

[0002] A laser cutting machine is a machine that uses laser light emitted from a laser source to focus into a high-power density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting point or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal, thereby achieving the purpose of cutting.

[0003] Prior art cantilevered dual-beam laser cutting machines, such as those described in publication number CN110315219A, typically utilize a cantilevered design. These cantilevered laser cutting machines typically include a fixed base, a cantilever, and a cutting head. The cantilever is moved laterally via a track mounted on the fixed base, while the cutting head is moved longitudinally and vertically via tracks mounted on the cantilever, thereby controlling the cutting head's three-dimensional movement. The cantilever is typically connected only to the fixed base, and an excessively long cantilever can easily cause the cutting machine to tip over.

[0004] The cantilever arm length of the laser cutting machine determines the cutting efficiency of the cutting machine. When the cantilever arm length is too short, the workpiece needs to be cut in sections, resulting in low cutting efficiency. Utility Model Content

[0005] In order to improve the working efficiency of the laser cutting machine and increase the arm length of the cantilever, the utility model provides a cantilever double-beam three-dimensional five-axis laser cutting machine.

[0006] A cantilever double-beam three-dimensional five-axis laser cutting machine includes a fixed seat, on which cutting arm mechanisms are symmetrically arranged. The two cutting arm mechanisms are respectively matched between the fixed seats through a lateral sliding structure. The lateral sliding structure enables the two cutting arm mechanisms to approach or move away from each other. A mounting surface for installing the lateral sliding structure is obliquely opened on the side of the fixed seat close to the cutting arm mechanism.

[0007] By adopting the above technical solution, the material is cut simultaneously on both sides of the material through two symmetrically arranged cutting arm mechanisms, thereby accelerating the cutting speed of the laser cutting machine and improving the working efficiency of the laser cutting machine. The transverse slide rail is installed on the inclined surface through the installation surface, thereby driving the center of gravity of the cutting arm mechanism to move toward the direction close to the fixed seat, so that the fixed seat can be installed with a longer cutting arm mechanism, further improving the cutting range and cutting speed of the laser cutting machine.

[0008] Preferably, the cutting arm mechanism includes a crossbeam and a sliding plate, the transverse sliding structure is arranged between the crossbeam and the fixed seat, and a longitudinal sliding structure is also arranged between the crossbeam and the sliding plate to enable the sliding plate to slide on the crossbeam, and the sliding direction of the crossbeam and the sliding direction of the sliding plate are perpendicular to each other.

[0009] By adopting the above technical solution, the crossbeam is slidably connected to the fixed seat through the transverse sliding structure, and the sliding plate is slidably connected to the crossbeam through the longitudinal sliding structure, so that the single cutting arm mechanism can move in two dimensions, thereby improving the convenience of using the laser cutting machine.

[0010] Preferably, the cutting arm mechanism further comprises a cutting head, the cutting head is connected to the sliding plate via a vertical sliding structure, and the sliding directions of the crossbeam, the sliding plate and the cutting head are perpendicular to each other.

[0011] By adopting the above technical solution, the cutting head is controlled to slide in three dimensions through the vertical sliding structure, the horizontal sliding structure and the longitudinal sliding structure, thereby improving the processing range and accuracy of the cutting head and improving the convenience of using the laser cutting machine.

[0012] Preferably, the lateral sliding structure includes a lateral slider and a lateral slide rail, the lateral slider is provided with a lateral slide groove for guiding the lateral slide rail, the lateral slide groove is equipped with an adjustment block, and the lateral slider is also provided with an adjustment mechanism for changing the position of the adjustment block in the lateral slide groove, thereby changing the groove width of the lateral slide groove.

[0013] By adopting the above technical solution, the width of the transverse slide groove is controlled by the adjustment block, so that the degree of cooperation between the transverse slider and the transverse slide rail can be adjusted as needed, thereby improving the convenience of fixing the cutting arm mechanism on the fixed seat or separating it from the fixed seat.

[0014] Preferably, the adjustment mechanism includes a screw rod rotatably connected to the transverse slider, the adjustment block is provided with a threaded hole cooperating with the screw rod, and one end of the screw rod passes through the transverse slider and is engaged with a driving structure.

[0015] By adopting the above technical solution, the adjusting block is controlled by the screw rod to move closer to or away from the transverse slider in the transverse slide groove, so that when installing the transverse slider, the adjusting block is controlled to move away from the transverse slider to facilitate installation, and after the installation is completed, the adjusting block is controlled to move closer to the transverse slider so that the adjusting block and the transverse slider clamp the transverse slide rail.

[0016] Preferably, the driving structure includes a passive gear and a gear sleeve, the passive gear is coaxially arranged at one end of the screw rod passing through the transverse slider, the gear sleeve is coaxially connected to the end of the screw rod passing through the transverse slider and is used to drive the passive gear to rotate, and a transmission gear for transmission is provided between the passive gear and the gear sleeve.

[0017] By adopting the above technical solution, the gear sleeve is turned to drive the passive gear and the screw to rotate, and the gear ratio between the gear sleeve and the passive gear is increased through the transmission gear, thereby improving the labor-saving effect of the gear sleeve and further improving the convenience of installing the horizontal slider.

[0018] Preferably, a buffer structure for buffering is provided between the transverse slider and the crossbeam, the buffer structure includes a buffer pad, a buffer pad protruding from the transverse slider is provided on the side of the transverse slider close to the cutting arm mechanism, a pressure plate for driving the buffer pad to protrude to the outside is slidably connected to the transverse slider, a pressure spring for driving the pressure plate to press the buffer pad is provided between the transverse slider and the pressure plate, and a limiting structure for limiting the pressure plate is also provided on the transverse slider.

[0019] By adopting the above technical solution, the vibration transmitted between the transverse slider and the crossbeam is reduced through the buffer structure, thereby improving the stability of the crossbeam when sliding on the fixed seat through the transverse sliding structure, and the buffer pad is pressed by the pressure plate, thereby driving the buffer pad close to the crossbeam, thereby improving the shock absorbing effect of the buffer pad.

[0020] Preferably, the limiting structure includes a sliding block that is slidably connected to the transverse slider, and a trigger block for the buffer pad to press is provided on the side of the sliding block close to the buffer pad, and a blocking block for limiting the pressure plate is provided on the side of the sliding block close to the pressure plate. The transverse slider is respectively provided with a penetration groove for the blocking block and the trigger block to pass through the slot, and a trigger compression spring is provided between the transverse slider and the sliding block to drive the sliding block close to the buffer pad.

[0021] By adopting the above technical solution, before the buffer pad is installed, the blocking block is pressed against the pressure plate, thereby limiting the pressure plate in the slot. When the buffer pad is installed, the trigger block is pressed and retracted into the sliding groove, thereby driving the blocking block to retract into the sliding groove along with the sliding block. At this time, the pressure plate is separated from the pressure of the blocking block, and then pressed in the direction of the buffer pad under the drive of the trigger compression spring, thereby driving the buffer pad to protrude from the protruding groove to the surface of the first horizontal slider.

[0022] Preferably, a fixing structure for fixing the buffer pad is further provided on the side of the transverse slider close to the pressure plate, and the fixing structure includes a pressure piece, and a shaft sleeve is provided on the transverse slider for threaded engagement with the pressure piece, and a protrusion is provided in the circumferential direction of the shaft sleeve, and a through groove is provided on the transverse slider for installation and rotation of the protrusion and the shaft sleeve, and a trigger rod is slidably connected to the transverse slider for passing through the through groove to press against the protrusion, and a trigger structure for driving the trigger rod to move is matched on the side of the trigger rod away from the shaft sleeve.

[0023] By adopting the above technical solution, the movement of the pressure piece is controlled by the trigger rod. When the trigger rod interferes with the protrusion, the sleeve cannot rotate circumferentially. At this time, twisting the pressure piece can control the pressure piece to press or move away from the buffer pad through the threaded cooperation between the pressure piece and the sleeve, thereby reducing the situation where the pressure piece is loosened due to accidental contact with the pressure piece.

[0024] Preferably, the trigger structure includes a ball for pressing the trigger rod, the ball is located in a transverse sliding groove, a ball compression spring is arranged between the ball and the transverse slider, the transverse slider is provided with a compression spring groove for installing the ball compression spring and the ball, and a cover ring is provided on the side of the transverse slider close to the ball for limiting the ball in the compression spring groove.

[0025] By adopting the above technical solution, when the clamping block has not entered the clamping groove, the ball is driven away from the first transverse slider by the ball compression spring. At this time, the trigger rod and the protrusion do not interfere with each other, and the sleeve and the pressure piece rotate synchronously when the pressure piece rotates. When the clamping block enters the clamping groove, the ball is pressed back into the compression spring groove by the clamping block. At this time, the trigger rod and the ball slide synchronously into the rotation groove, and the trigger rod presses against the protrusion, thereby driving the sleeve and the pressure piece to be unable to rotate synchronously, and then the pressure piece is twisted and pressed against the pressure plate, thereby improving the stability of the buffer pad installation.

[0026] In summary, the present invention has at least one of the following beneficial technical effects:

[0027] 1. The two symmetrically arranged cutting arms cut the material simultaneously on both sides, thereby increasing the cutting speed of the laser cutting machine and improving the working efficiency of the laser cutting machine. The horizontal slide rail is installed on the inclined surface through the mounting surface, thereby driving the center of gravity of the cutting arm mechanism to move closer to the fixed base, thereby enabling the fixed base to install a longer cutting arm mechanism, further improving the cutting range and cutting speed of the laser cutting machine;

[0028] 2. The crossbeam is slidably connected to the fixed seat through a transverse sliding structure, and the sliding plate is slidably connected to the crossbeam through a longitudinal sliding structure, so that the single cutting arm mechanism can move in two dimensions, thereby improving the convenience of using the laser cutting machine;

[0039] The following is combined with Figure 1 -Attached Figure 8 The utility model is described in further detail.

[0040] Reference Figure 1The embodiment of the utility model discloses a cantilever double-beam 21 three-dimensional five-axis laser cutting machine, comprising a fixed seat 1, a cutting arm mechanism 2, a transverse slide rail 32 and a transverse slider 31. The cutting arm mechanism 2 is slidably connected to the fixed seat 1. In this embodiment, two cutting arm mechanisms 2 are symmetrically arranged. The fixed seat 1 is provided with a mounting surface 11 for mounting the cutting arm mechanism 2. The mounting surface 11 is obliquely opened to offset the center of gravity of the cutting arm mechanism 2 in a direction close to the fixed seat 1, so that the fixed seat 1 can install a cutting arm mechanism 2 with a longer arm length. The transverse slide rail 32 includes a first transverse slide rail 32 and a second transverse slide rail 32, both of which are fixed to the fixed seat 1 by bolts, and the vertical height of the first transverse slide rail 32 is greater than the vertical height of the second transverse slide rail 32.

The first transverse slider 31 and the second transverse slider 31 are both provided with transverse slide grooves 33 for the slide rails to slide and limit.

[0041] Reference Figure 1 Anti-collision mechanisms 12 are provided in the direction in which the cutting arm mechanisms 2 approach each other. When the cutting arm mechanisms 2 approach each other too closely, the anti-collision mechanisms 12 press against each other to prevent the cutting arm mechanisms 2 from continuing to approach each other, thereby interfering with each other and causing damage. The anti-collision mechanisms 12 are also provided at both ends of the fixed base 1. The anti-collision mechanisms 12 are located on the mounting surface 11. The anti-collision mechanisms 12 on the fixed base 1 prevent the cutting arm mechanisms 2 from disengaging from the first transverse slide rail 32 or the second transverse slide rail 32, thereby causing them to detach from the fixed base 1.

[0042] Reference Figure 1 and Figure 2 The cutting arm mechanism 2 includes a crossbeam 21, a sliding plate 22, a longitudinal sliding structure 23, a pressure block 234, a cutting head 24, and a vertical sliding structure 25. A first crossbeam 31 and a second crossbeam 31 are bolted to the crossbeam 21. The sliding plate 22 is slidably connected to one side of the crossbeam 21 via the longitudinal sliding structure 23. The longitudinal sliding structure 23 includes a longitudinal rail 231, a longitudinal slider 232, and a pressure block 234. The longitudinal rail 231 is symmetrically bolted to the side of the crossbeam 21 near the sliding plate 22. The longitudinal slider 232 is bolted to the side of the sliding plate 22 near the longitudinal rail 231. The longitudinal slider 232 is provided with a longitudinal slot 233 for the longitudinal rail 231 to slide and limit its position. The pressure block 234 is bolted to the side of the crossbeam 21 near the longitudinal slider 232. The pressure block 234 presses against the longitudinal slider 232, thereby improving the sliding stability of the longitudinal slider 232.

[0043] Reference Figure 2 and Figure 3 The cutting head 24 is slidably connected to the side of the sliding plate 22 away from the crossbeam 21 via a vertical sliding structure 25. The vertical sliding structure 25 includes a vertical slide rail 251 and a vertical slider 252. The vertical slide rail 251 is symmetrically fixed to the side of the cutting head 24 close to the sliding plate 22 by bolts, and the vertical slider 252 is also fixed to the side of the sliding plate 22 close to the vertical slide rail 251 by bolts. The sliding directions of the crossbeam 21, sliding plate 22, and cutting head 24 are perpendicular to each other. The crossbeam 21, sliding plate 22, and cutting head 24 are slidably connected and limited by the cooperation of the slider and the slide rail.

[0044] Reference Figure 3 and Figure 4 The first and second transverse sliders 31, 31, longitudinal slider 232, and vertical slider 252 are all integrally provided with limiting protrusions 36 for limiting the position. The limiting protrusions 36 are symmetrically arranged on the first and second transverse sliders 31, 31, longitudinal slider 232, and vertical slider 252. The limiting protrusions 36 on the first and second transverse sliders 31 are located within the transverse grooves 33 and are not located at the bottom of the transverse grooves 33. The first and second transverse rails 32 and 32 are provided with limiting grooves for the limiting protrusions 36 to slide and limit the position. The limiting protrusions 36 on the longitudinal slider 232 are located within the longitudinal grooves 233 and are not located at the bottom of the longitudinal grooves 233. The longitudinal rails 231 are provided with limiting grooves for the limiting protrusions 36 to slide and limit the position. The limiting protrusion 36 on the vertical slide 252 is located in the vertical slide groove 253 , and the limiting protrusion 36 is not located at the bottom of the vertical slide groove 253 . A limiting groove for the limiting protrusion 36 to slide and limit is opened on the vertical slide rail 251 .

[0045] Reference Figure 4 The second transverse slider 31 is provided with an adjustment block 34 for adjusting the width of the transverse chute 33 and an adjustment mechanism 35 for adjusting the position of the adjustment block 34. The adjustment block 34 is slidably connected to the side of the second transverse slider 31 near the second transverse rail 32, and the adjustment block 34 is located within the transverse chute 33. The adjustment mechanism 35 includes a screw rod 351 and a drive structure 352. The screw rod 351 is rotatably connected to the side of the second transverse slider 31 near the adjustment block 34 and is threadedly engaged with the adjustment block 34. The adjustment block 34 is provided with a threaded hole 341 for threading with the screw rod 351. The second transverse slider 31 is provided with a through hole 37 for rotatably connecting the screw rod 351 and extending to the outside.

[0046] Reference Figure 4The drive structure 352 includes a driven gear 3521, a gear sleeve 3522, and a transmission gear 3523. The driven gear 3521 is coaxially arranged at the end of the screw rod 351 that extends outward. The gear sleeve 3522 is coaxially rotatably connected to the end of the screw rod 351 that extends outward. The transmission gear 3523 is rotatably connected to the side of the second transverse slider 31 near the driven gear 3521. One side of the transmission gear 3523 meshes with the driven gear 3521, and the other side of the transmission gear 3523 meshes with the gear sleeve 3522. Turning the gear sleeve 3522 causes the gear sleeve 3522 to rotate, thereby driving the driven gear 3521 and the screw rod 351 to rotate synchronously. Anti-slip grooves can be added to the gear sleeve 3522 to improve its ease of use. The transmission gear 3523 increases the gear ratio between the gear sleeve 3522 and the driven gear 3521, thereby improving the labor-saving effect of the gear sleeve 3522.

[0047] Reference Figure 4 , combined with Figure 1 The first transverse slider 31 is used to connect the cutting arm mechanism 2 with the first transverse slide rail 32 on the fixed seat 1. The connection strength between the cutting arm mechanism 2 and the first transverse slide rail 32 can be improved by adding the first transverse slider 31. A snap-fitting strip 313 is integrally provided on one side of the first transverse slider 31. In this embodiment, the snap-fitting strip 313 is arranged in a "T" shape. The other side of the first transverse slider 31 is provided with a snap-fitting groove 314 for the snap-fitting strip 313 to snap into. One end of the snap-fitting groove 314 is connected to the outside. The snap-fitting strip 313 is pressed against the first transverse slider 31 in the snap-fitting groove 314, thereby improving the connection strength of adjacent first transverse sliders 31. The snap-fitting direction of the snap-fitting strip 313 is perpendicular to the sliding direction of the first transverse slider 31 to reduce the separation of the first transverse slider 31.

[0048] Reference Figure 5 and Figure 6 , combined with Figure 1 A buffer structure 4 is provided on the side of the first transverse slider 31 near the cutting arm mechanism 2. The buffer structure 4 includes a buffer pad 41, which is arranged in a "convex" shape. The first transverse slider 31 has a slot 316 for inserting the buffer pad 41. The first transverse slider 31 also has a protruding groove 315 for the buffer pad 41 to protrude from the surface of the first transverse slider 31. The protruding groove 315 is connected to the slot 316. The buffer pad 41 presses against the first transverse slider 31 within the slot 316, thereby improving the stability of the buffer pad 41 installation.

[0049] Reference Figure 6A pressure plate 42 is slidably connected to the side of the first transverse slider 31 near the buffer pad 41. The pressure plate 42 is located in the slot 316. A pressure spring 43 is provided between the pressure plate 42 and the first transverse slider 31 for forcing the pressure plate 42 to press against the buffer pad 41. A limiting structure 44 for controlling the pressure state of the pressure plate 42 and a fixing structure 45 for fixing the pressure plate 42 are provided on the side of the first transverse slider 31 near the buffer pad 41.

[0050] Reference Figure 6 and Figure 7 The limiting structure 44 includes a sliding block 441 that is slidably connected to the first transverse slider 31. The first transverse slider 31 defines a sliding groove 318 for the sliding block 441 to slide. A trigger spring 444 is disposed between the sliding block 441 and the first transverse slider 31 for driving the sliding block 441 toward the buffer pad 41. The trigger spring 444 is located within the sliding groove 318. A trigger block 442 is integrally disposed on the side of the sliding block 441 near the buffer pad 41, which is pressed by the buffer pad 41 to cause the sliding block 441 to retract into the sliding groove 318. A blocking block 443 is integrally disposed on the side of the sliding block 441 near the pressure plate 42 for limiting the position of the pressure plate 42. The first transverse slider 31 defines a penetration groove 311 for the trigger block 442 and the pressure block 234 to pass from the sliding groove 318 to the slot 316.

[0051] Reference Figure 6 and Figure 8 The fixing structure 45 includes a pressing member 451 for pressing the pressing plate 42 so that the pressing plate 42 presses the buffer pad 41. The pressing member 451 is arranged on the side of the first transverse slider 31 close to the pressing plate 42. The first transverse slider 31 is provided with a through groove 312 for the pressing member 451 to pass from the transverse slide 33 to the slot 316. The first transverse slider 31 is provided with a shaft sleeve 452 on the side close to the pressing member 451. The shaft sleeve 452 is coaxially provided with a shaft sleeve for the pressing member 451. The threaded cavity 4521 is threadedly engaged with the sleeve 452, and a protrusion 453 is integrally provided circumferentially on the sleeve 452. The sleeve 452 and the protrusion 453 are mounted and rotated in the through-slot 312. A trigger rod 454 is slidably connected to the side of the first transverse slider 31 near the protrusion 453, which is used to press against the protrusion 453 to prevent the sleeve 452 and the protrusion 453 from rotating. The first transverse slider 31 is provided with a through-slot 319 for the trigger rod 454 to pass from the compression spring groove 317 into the through-slot 312. A trigger structure 455 is provided on the side of the first transverse slider 31 near the trigger rod 454 for controlling the trigger state of the trigger rod 454.

[0052] Reference Figure 8The trigger structure 455 includes a ball bearing 4551 disposed on the side of the first transverse slider 31 near the trigger rod 454. The ball bearing 4551 is located at the bottom of the engaging groove 314. The ball bearing 4551 and the trigger rod 454 can be integrally or separately arranged. In this embodiment, the integral arrangement of the ball bearing 4551 and the trigger rod 454 is used as an example. A ball bearing compression spring 4552 is disposed between the ball bearing 4551 and the first transverse slider 31. The first transverse slider 31 defines a compression spring groove 317 for mounting the ball bearing 4551 and the ball bearing compression spring 4552. A cover ring 4553 is welded to the first transverse slider 31 to retain the ball bearing 4551 within the compression spring groove 317.

[0053] Working principle:

[0054] When the buffer pad 41 is not installed, the blocking block 443 presses against the pressure plate 42, thereby limiting the pressure plate 42 to the bottom of the slot 316. When the buffer pad 41 is inserted into the slot 316, the buffer pad 41 presses against the trigger block 442, thereby driving the trigger block 442 to retreat into the sliding groove 318. At this time, the sliding block 441 and the blocking block 443 retreat synchronously with the trigger block 442 into the sliding groove 318, thereby causing the blocking block 443 to disengage from the pressure plate 42. The pressure plate 42 is pressed against the buffer pad 41 under the drive of the pressure spring 43.

[0055] When the locking block has not entered the locking groove 314, the ball 4551 is pressed in the direction away from the first transverse slider 31 under the drive of the ball compression spring 4552, so that the ball 4551 passes through the cover ring 4553 and is set into the locking groove 314. At this time, the trigger rod 454 does not interfere with the protrusion 453 in the through groove 319. When the pressing piece 451 is screwed, the sleeve 452 rotates synchronously with the pressing piece 451, resulting in the pressing piece 451 being unable to be threadedly engaged with the sleeve 452. When the engaging block enters the engaging groove 314, the engaging block presses against the ball 4551, thereby driving the ball 4551 back into the compression spring groove 317, and then causing the trigger rod 454 to slide in the through groove 319 toward the side close to the protrusion 453. At this time, the protrusion 453 interferes with the trigger rod 454. When the pressing member 451 is twisted, the protrusion 453 presses against the trigger rod 454, so that the sleeve 452 cannot rotate synchronously with the pressing member 451, and then the pressing member 451 and the sleeve 452 are threadedly engaged to drive the pressing member 451 close to or away from the pressing plate 42.

[0056] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
