Description

Technical Field

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

[0002] Laser cutting machine refers to a machine that uses laser light emitted from a laser device 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] In the prior art, such as a cantilever double-beam laser cutting machine with publication number CN1 10315219A, a cantilever laser cutting machine is generally used. The cantilever laser cutting machine generally includes a fixed seat, a cantilever and a cutting head. The cantilever is moved horizontally by a track set on the fixed seat, and the cutting head is moved longitudinally and vertically by a track set on the cantilever, thereby controlling the cutting head to move in three dimensions. The cantilever is generally only connected to the fixed seat, and when the cantilever is too long, it is easy to 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 lower cutting efficiency. Summary of the invention

[0005] In order to improve the working efficiency of a laser cutting machine and increase the arm length of a cantilever, the present invention 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, and two cutting arm mechanisms are respectively matched between the fixed seats through a lateral sliding structure, and 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 one 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 plane 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 lateral 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 achieve two-dimensional movement, 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 direction of 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 lateral 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, an adjustment block is provided in the lateral slide groove, 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 coordination 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 comprises 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 is matched with a driving structure after passing through the transverse slider.

[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 rotatably 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 arranged 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 arranged between the transverse slider and the cross beam, the buffer structure includes a buffer pad, a buffer pad protruding from the transverse slider is arranged 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 arranged between the transverse slider and the pressure plate, and a limiting structure for limiting the pressure plate is also arranged 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 slidably connected to the transverse slider, a trigger block for pressing the buffer pad is arranged on the side of the sliding block close to the buffer pad, a blocking block for limiting the pressure plate is arranged on the side of the sliding block close to the pressure plate, and the transverse slider is respectively provided with through grooves for the blocking block and the trigger block to pass through the slot, and a trigger compression spring is arranged 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 transverse slider.

[0022] Preferably, a fixing structure for fixing the buffer pad is provided on the side of the transverse slider close to the pressure plate, the fixing structure includes a pressure piece, a sleeve is provided on the transverse slider for threaded cooperation with the pressure piece, a protrusion is provided in the circumferential direction of the sleeve, a through groove is provided on the transverse slider for installation and rotation of the protrusion and the sleeve, 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 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 becomes loose 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 slide 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 for limiting the ball in the compression spring groove is arranged on the side of the transverse slider close to the ball.

[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 rotating 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 includes at least one of the following beneficial technical effects:

[0027] 1. The two symmetrically arranged cutting arm mechanisms cut the material on both sides of the material at the same time, thereby speeding up 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 plane 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;

[0028] 2. The crossbeam is slidably connected to the fixed seat through the lateral 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;

[0029] 3.

DETAILED DESCRIPTION

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

[0040] Reference Figure 1The embodiment of the present invention 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 shift the center of gravity of the cutting arm mechanism 2 toward the 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.

[0041] Reference Figure 1 The anti-collision mechanism 12 is arranged in the direction where the cutting arm mechanisms 2 approach each other. When the cutting arm mechanisms 2 are too close, the anti-collision mechanism 12 presses against each other to reduce the situation where the cutting arm mechanisms 2 continue to approach each other, causing interference between the cutting arm mechanisms 2, and then causing damage. The anti-collision mechanism 12 is also arranged at both ends of the fixing seat 1. The anti-collision mechanism 12 is located on the mounting surface 11. The anti-collision mechanism 12 on the fixing seat 1 reduces the situation where the cutting arm mechanism 2 deviates from the first transverse slide rail 32 or the second transverse slide rail 32, thereby causing the cutting arm mechanism 2 to deviate from the fixing seat 1.

The protruding groove 315 is connected to the slot 316. The buffer pad 41 is pressed against the first transverse slider 31 in the slot 316, thereby improving the stability of the installation of the buffer pad 41.

A trigger block 442 is integrally provided on the side of the sliding block 441 close to the buffer pad 41 for the buffer pad 41 to press the sliding block 441 to make the sliding block 441 retreat into the sliding groove 318. A blocking block 443 is integrally provided on the side of the sliding block 441 close to the pressing plate 42 for limiting the pressing plate 42. A penetration groove 311 is provided on the first transverse slider 31 for the trigger block 442 and the pressing block 234 to penetrate from the sliding groove 318 to the slot 316.

[0051] Reference Figure 6 and Figure 8 The fixing structure 45 includes a pressing piece 451 for pressing the pressing plate 42 so that the pressing plate 42 presses the buffer pad 41. The pressing piece 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 piece 451 to pass through the transverse slide groove 33 to the slot 316. The first transverse slider 31 is provided with a shaft sleeve 452 on the side close to the pressing piece 451. The shaft sleeve 452 is coaxially provided with a through groove 312 for the pressing piece 451 to pass through the transverse slide groove 33 to the slot 316. The threaded cavity 4521 is threadedly matched, and a protrusion 453 is integrally provided on the circumferential direction of the sleeve 452. The through groove 312 is used for the sleeve 452 and the protrusion 453 to be installed and rotated. The first transverse slider 31 is slidably connected to the side close to the protrusion 453 with a trigger rod 454 for pressing the protrusion 453 to prevent the sleeve 452 and the protrusion 453 from rotating. The first transverse slider 31 is provided with a through groove 319 for the trigger rod 454 to pass from the compression spring groove 317 to the through groove 312. The first transverse slider 31 is provided with a trigger structure 455 for controlling the trigger state of the trigger rod 454 on the side close to the trigger rod 454.

[0052] Reference Figure 8The trigger structure 455 includes a ball 4551 disposed on the side of the first transverse slider 31 close to the trigger rod 454. The ball 4551 is located at the bottom of the clamping groove 314. The ball 4551 and the trigger rod 454 can be integrally arranged or separately arranged. In this embodiment, the integrally arranged ball 4551 and the trigger rod 454 are taken as an example. A ball compression spring 4552 is arranged between the ball 4551 and the first transverse slider 31. The first transverse slider 31 is provided with a compression spring groove 317 for installing the ball 4551 and the ball compression spring 4552. A cover ring 4553 is welded on the first transverse slider 31 to limit the ball 4551 in the compression spring groove 317.

[0053] Working principle:

[0054] When the buffer pad 41 is not installed, the blocking block 443 is pressed against the pressure plate 42, thereby limiting the pressure plate 42 at the bottom of the slot 316. When the buffer pad 41 is inserted into the slot 316, the buffer pad 41 is pressed 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 are synchronously retreated into the sliding groove 318 with the trigger block 442, thereby causing the blocking block 443 to detach 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 a direction away from the first transverse slider 31 by the ball compression spring 4552, so that the ball 4551 passes through the cover ring 4553 and is arranged in 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 inability of the pressing piece 451 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 to retreat into the compression spring groove 317, and then the trigger rod 454 slides 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 piece 451 is twisted, the protrusion 453 presses against the trigger rod 454, so that the sleeve 452 cannot rotate synchronously with the pressing piece 451, and then the pressing piece 451 and the sleeve 452 are threadedly matched to drive the pressing piece 451 to approach or move away from the pressing plate 42.

[0056] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope 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 protection scope of the present invention.
