Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, specifically to a multi-angle adjustable laser cutting machine. Background Technology

[0002] Laser cutting utilizes a focused, high-power-density laser beam to irradiate the workpiece, causing the irradiated material to rapidly melt, vaporize, ablate, or reach its ignition point. Simultaneously, a high-speed airflow coaxial with the laser beam blows away the molten material, thereby cutting the workpiece.

[0003] Patent CN217647724U discloses a device for multi-angle laser cutting, comprising a worktable with a slidable ring frame on top. The ring frame is a hollow circular shell, and an adjustment plate is slidably mounted inside. A laser cutter is mounted on top of the adjustment plate. A linkage block is also slidably mounted inside the ring frame, and an arc-shaped spring is provided between the linkage block and the adjustment plate. The center points of the linkage block, adjustment plate, and ring frame are aligned on a straight line. A baffle is provided on the upper and lower surfaces of the linkage block. This patent allows the adjustment plate to drive the laser cutter to change the cutting angle, and ensures that the center points of the linkage block, adjustment plate, and ring frame are aligned, guaranteeing that the baffle continuously blocks the laser beam from shining outwards. This facilitates multi-angle laser cutting adjustment while ensuring cutting safety. Although this patent solves the aforementioned problems, it still suffers from unstable clamping, leading to workpiece drop and damage after cutting. Therefore, a multi-angle adjustable laser cutting machine is proposed to address these issues. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a multi-angle adjustable laser cutting machine to address the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a multi-angle adjustable laser cutting machine, including a base, a motor disposed on the top of the base, a spiral rod fixedly connected to the output end of the motor, a limit rod fixedly connected to the top of the base, a welding mechanism disposed on the outer circumference of the spiral rod, a clamping mechanism disposed on the top of the base, a sliding groove disposed on the top of the base, and a rotating handle rotatably connected to the left side of the base. The welding mechanism includes a laser head, an inner ring block, a fixed circular groove, and a protective plate, the fixed circular groove being disposed on the outer circumference of the spiral rod. On the circumference, the inner ring block is slidably connected to the inner surface of the fixed circular groove, the laser head is set on the outer surface of the inner ring block, and the protective plate is set on the outer surface of the inner ring block. When cutting the workpiece, the motor is started to rotate the screw rod, allowing the fixed circular groove to move up and down under the restriction of the limit rod. When it moves to the position to be cut, the motor is turned off, and the laser head is turned on to drive the inner ring block to rotate the laser head, performing multi-angle circumferential cutting on the workpiece. The protective plate on the outer surface of the inner ring block is always directly opposite the output end of the laser head to prevent excessive laser heat from damaging the welding device.

[0006] Preferably, the clamping mechanism includes a clamping platform, a connecting rod, a fixing ring, a welding platform, and a bidirectional screw. The clamping platform is slidably connected to the inner surface of the slide groove, the connecting rod is rotatably connected to the rear of the clamping platform, the fixing ring is rotatably connected to the rear of the connecting rod, the welding platform is disposed on the top of the machine base, and the bidirectional screw is rotatably connected inside the clamping platform. The clamping mechanism also includes a triangular clamp, a limiting groove, a return spring, a long block, and a limiting post. The limiting groove is fixedly connected to the bottom of the clamping platform, the limiting post is slidably connected to the inner surface of the limiting groove, the long block is fixedly connected to the top of the limiting post, and the triangular clamp is fixedly connected to the long block. At the front, one end of the return spring is fixedly connected to the outer surface of the long block, and the other end of the return spring is fixedly connected to the bottom of the clamping platform. The long block is slidably connected to the bottom of the clamping platform. The rotating handle is fixedly connected to the left side of the bidirectional screw. A fixing mechanism is provided on the outer surface of the inner ring block. The fixing mechanism includes a device plate, a second return spring, an anti-breakage plate, and a telescopic rod. The device plate is fixedly connected to the outer circumferential surface of the inner ring block. The telescopic rod is located on the left side of the device plate. The anti-breakage plate is fixedly connected to the left side of the telescopic rod. One end of the second return spring is fixedly connected to the left side of the device plate, and the other end of the second return spring is fixedly connected to the right side of the anti-breakage plate. The workpiece to be cut is placed manually on the welding table. Then, rotate the handle to make the double screw rotate, causing the two clamping platforms on both sides to converge towards the center. When the clamping platforms converge to a certain position, the triangular clamp contacts the workpiece. At the same time, under the pressure of the workpiece, the long block at the rear of the triangular clamp presses the return spring, causing the limiting post to move only within the limiting groove. Simultaneously, as the clamping platforms converge towards the workpiece in the center, they will press the connecting rod to rotate towards the center, while simultaneously causing the left and right fixing rings to converge towards the center. Under the elastic action of the return spring, the triangular clamp moves inside the limiting groove, achieving a good clamping effect for workpieces of different diameters. Under the action of the connecting rod, the fixing rings converge towards the center, which can fix the two sides of the workpiece, achieving a better workpiece fixing effect.

[0007] Preferably, in another embodiment of the present invention, the fixing mechanism further includes an inclined plate, a vertical drive wheel, a horizontal drive wheel, a rotating rod, bristles, a deburring wheel, and a torsion spring column. The inclined plate is fixedly connected to the bottom of the anti-scraping plate, the vertical drive wheel is rotatably connected to the bottom of the inclined plate, the rotating rod is rotatably connected to the inner surface of the anti-scraping plate, the bristles are disposed on the outer circumferential surfaces at both ends of the rotating rod, the deburring wheel is disposed on the outer circumferential surface of the rotating rod, the horizontal drive wheel is fixedly connected to the outer circumferential surface of the rotating rod, the deburring wheel contacts the workpiece, and the horizontal drive wheel is fixedly connected to the bottom of the rotating rod. When the workpiece is fixed by the clamping mechanism, the motor starts and drives the inner ring block to move downward. When the inclined plate contacts the top of the workpiece, the vertical drive wheel... Driven by the wheel, the return spring retracts under the pressure of the workpiece, and then the inner ring block continues to move downward, so that the anti-scraping plate contacts the circumferential surface of the workpiece. After the anti-scraping plate contacts the workpiece, the transverse transmission wheels on both sides will also contact the surface. While cutting, the inner ring block rotates, causing the transverse transmission wheels to rotate with friction against the workpiece surface, thereby driving the brush and deburring wheel to rotate. Under the friction transmission of the transmission wheel on the workpiece surface, the brush and deburring wheel rotate on the workpiece surface. The brush removes impurities from the workpiece surface, and the deburring wheel can grind off the burrs after cutting. At the same time, under the protection of the anti-scraping plate, the risk of personnel injury caused by the workpiece falling after cutting is prevented.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0009] 1. This multi-angle adjustable laser cutting machine, with the cooperation of the laser head, inner ring block, laser head and protective plate, turns on the laser head during cutting to drive the inner ring block to rotate the laser head and cut the workpiece at multiple angles on the circumference. The protective plate on the outer surface of the inner ring block is always directly opposite the output end of the laser head to prevent the laser heat from being too high and causing damage to the welding device.

[0010] 2. This multi-angle adjustable laser cutting machine, through the interaction of the return spring, triangular clamp, limiting groove, connecting rod, and fixing ring, and under the elastic action of the return spring, moves the triangular clamp inside the limiting groove, achieving a good clamping effect for workpieces of different diameters. Under the action of the connecting rod, the fixing ring is brought together to the center, which can fix the two sides of the workpiece, achieving a better workpiece fixing effect.

[0011] 3. This multi-angle adjustable laser cutting machine, with the cooperation of the anti-scraping plate, horizontal drive wheel, inner ring block, and brush deburring wheel, ensures that after the anti-scraping plate contacts the workpiece, the horizontal drive wheels on both sides also contact the surface. During cutting, the inner ring block rotates, causing the horizontal drive wheel to rotate due to friction with the workpiece surface, thereby driving the brush and deburring wheel to rotate. Under the friction transmission of the drive wheel on the workpiece surface, the brush and deburring wheel rotate on the workpiece surface. The brush removes impurities from the workpiece surface, and the deburring wheel grinds off the burrs after cutting. At the same time, under the protection of the anti-scraping plate, the risk of personnel injury from the workpiece falling after cutting is prevented. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-8One embodiment of the present invention is: a multi-angle adjustable laser cutting machine, including a base 1, a motor 2 disposed on the top of the base 1, a spiral rod 4 fixedly connected to the output end of the motor 2, a limit rod 3 fixedly connected to the top of the base 1, a welding mechanism 6 disposed on the outer circumferential surface of the spiral rod 4, a clamping mechanism 7 disposed on the top of the base 1, a sliding groove 9 disposed on the top of the base 1, and a rotating handle 5 rotatably connected to the left side of the base 1. The welding mechanism 6 includes a laser head 601, an inner ring block 602, a fixed circular groove 603, and a protective plate 604. The fixed circular groove 603 is disposed on the outer circumferential surface of the spiral rod 4, and the inner ring block 602 is slidably connected to the fixed handle 604. The inner surface of the circular groove 603 is covered by a laser head 601, which is located on the outer surface of the inner ring block 602. A protective plate 604 is also located on the outer surface of the inner ring block 602. When cutting the workpiece, the motor 2 is started to rotate the spiral rod 4, allowing the fixed circular groove 603 to move up and down under the restriction of the limit rod 3. When it moves to the position where it needs to be cut, the motor 2 is turned off, and the laser head 601 is turned on to drive the inner ring block 602 to rotate the laser head 601, thus performing multi-angle circumferential cutting on the workpiece. The protective plate 604 on the outer surface of the inner ring block 602 is always directly opposite the output end of the laser head 601 to prevent excessive laser heat from damaging the welding device.

[0023] The clamping mechanism 7 includes a clamping platform 701, a connecting rod 702, a fixing ring 703, a welding table 704, and a bidirectional screw 705. The clamping platform 701 is slidably connected to the inner surface of the slide groove 9. The connecting rod 702 is rotatably connected to the rear of the clamping platform 701. The fixing ring 703 is rotatably connected to the rear of the connecting rod 702. The welding table 704 is located on the top of the machine base 1. The bidirectional screw 705 is rotatably connected inside the clamping platform 701. The clamping mechanism 7 also includes a triangular clamp 706, a limiting groove 707, a return spring 708, a long block 709, and a limiting post 710. The limiting groove 707 is fixedly connected to the bottom of the clamping platform 701. The limiting post 710 is slidably connected to the inner surface of the limiting groove 707. The long block 709 is fixedly connected to the top of the limiting post 710. The triangular clamp 706 is fixedly connected to the long block 706. At the front of 09, one end of the reset spring 708 is fixedly connected to the outer surface of the long block 709, and the other end of the reset spring 708 is fixedly connected to the bottom of the clamping platform 701. The long block 709 is slidably connected to the bottom of the clamping platform 701. The rotating handle 5 is fixedly connected to the left side of the bidirectional screw 705. A fixing mechanism 8 is provided on the outer surface of the inner ring block 602. The fixing mechanism 8 includes a device plate 801, a reset spring 802, an anti-collapse plate 803, and a telescopic rod 804. The device plate 801 is fixedly connected to the outer circumferential surface of the inner ring block 602. The telescopic rod 804 is located on the left side of the device plate 801. The anti-collapse plate 803 is fixedly connected to the left side of the telescopic rod 804. One end of the reset spring 802 is fixedly connected to the left side of the device plate 801, and the other end of the reset spring 802 is fixedly connected to the right side of the anti-collapse plate 803.

[0024] Working principle: When cutting the workpiece, the motor 2 is started to rotate the spiral rod 4, allowing the fixed circular groove 603 to move up and down under the restriction of the limit rod 3. When it moves to the position to be cut, the motor 2 is turned off, and the laser head 601 is turned on to drive the inner ring block 602 to rotate the laser head 601, which performs multi-angle cutting on the circumferential surface of the workpiece. The outer surface protective plate 604 of the inner ring block 602 is always directly opposite the output end of the laser head 601 to prevent the laser heat from being too high and damaging the welding device.

[0025] The workpiece to be cut is placed manually on the welding table 704. Then, the handle 5 is rotated to rotate the double-acting screw 705, causing the two clamping platforms 701 to converge towards the center. When the clamping platforms 701 converge to a certain position, the triangular clamp 706 contacts the workpiece. At the same time, under the pressure of the workpiece, the long block 709 at the rear of the triangular clamp 706 presses the return spring 708, causing the limiting post 710 to move only within the limiting groove 707. Simultaneously, as the clamping platforms 701 converge towards the workpiece, they press the connecting rod 702 to rotate towards the center, simultaneously causing the left and right fixing rings 703 to converge towards the center. Under the elastic action of the return spring 708, the triangular clamp 706 moves within the limiting groove 707, achieving a good clamping effect for workpieces of different diameters. Under the action of the connecting rod 702, the fixing rings 703 converge towards the center, which can fix the two sides of the workpiece, achieving a better workpiece fixing effect.

[0026] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the fixing mechanism 8 further includes an inclined plate 805, a vertical transmission wheel 806, a horizontal transmission wheel 807, a rotating rod 808, a brush 809, a deburring wheel 810, and a torsion spring column 811. The inclined plate 805 is fixedly connected to the bottom of the anti-scraping plate 803, the vertical transmission wheel 806 is rotatably connected to the bottom of the inclined plate 805, the rotating rod 808 is rotatably connected to the inner surface of the anti-scraping plate 803, the brush 809 is disposed on the outer circumferential surface at both ends of the rotating rod 808, the deburring wheel 810 is disposed on the outer circumferential surface of the rotating rod 808, the horizontal transmission wheel 807 is fixedly connected to the outer circumferential surface of the rotating rod 808, the deburring wheel 810 contacts the workpiece, and the horizontal transmission wheel 807 is fixedly connected to the bottom of the rotating rod 808.

[0027] Working principle: After the workpiece is fixed by the clamping mechanism 7, the motor 2 starts and drives the inner ring block 602 to move downward. When the inclined plate 805 contacts the top of the workpiece, under the transmission of the vertical transmission wheel 806 and the pressure of the workpiece, the return spring 802 contracts. Then the inner ring block 602 continues to move downward, so that the anti-breakage plate 803 contacts the circumferential surface of the workpiece. After the anti-breakage plate 803 contacts the workpiece, the horizontal transmission wheels 807 on both sides will also contact the surface. At the same time as cutting, the inner ring block 602 rotates, so that the horizontal transmission wheels 807 rub against the workpiece surface and rotate, thereby driving the brush 809 and the deburring wheel 810 to rotate. Under the friction transmission of the transmission wheel on the workpiece surface, the brush 809 and the deburring wheel 810 rotate on the workpiece surface. The brush 809 removes impurities from the workpiece surface, and the deburring wheel 810 can grind off the burrs after cutting. At the same time, under the protection of the anti-breakage plate 803, the risk of the workpiece falling and causing injury to personnel after cutting is prevented.
