Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of laser cutting, in particular to a motorcycle pipe laser cutting device and a use method thereof. BACKGROUND

[0002] Laser cutting is to use high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to vaporization temperature, evaporated to form a hole, and as the light beam moves on the material, the hole continuously forms a narrow cutting seam, and the cutting of the material is completed. After the laser beam is focused, a very small action point with extremely strong energy is formed. The laser energy can be converted into amazing heat energy and maintained in a very small area. It can provide a narrow straight edge cutting seam, a minimum heat affected zone of adjacent cutting edge and a very small local deformation. In addition, the laser beam does not exert any force on the workpiece, which is a non-contact cutting tool. This means that the workpiece has no mechanical deformation and no tool wear. Therefore, it is very convenient to combine with automatic equipment and easy to realize cutting process automation.

[0003] When the motorcycle pipe is processed, the parts at the exhaust pipe cover of the motorcycle need to be cut out. The cut-out pattern of part of the motorcycle exhaust pipe is asymmetric or rotationally symmetric. At this time, when the laser cuts the tubular part, the laser will cut the bottom of the inner surface of the tubular part after penetrating the upper part of the tubular part, which is not convenient for cutting the asymmetric or rotationally symmetric cut-out pattern on the tubular part.

[0012] Furthermore, a second aspect of this application provides a method for laser cutting motorcycle pipe fittings, using the aforementioned laser cutting device for motorcycle pipe fittings, the method comprising the following steps:

[0013] S1. First, fix the pipe to be processed on the three-jaw chuck. Then, use the electric push rod to adjust the lifting frame so that the relative height between the baffle and the laser head is adapted to the size of the pipe. At this time, adjust the height of the adjusting seat and the X and Y axis positions through the adjusting part so that the laser head is above the pipe and the baffle extends into the inner surface of the pipe.

[0014] S2. The laser beam emitted by the laser head is used to cut the pipe.

This makes it easy to ensure the baffle's blocking effect on the laser beam.

[0020] (2) This application will also drive the protective component to move while releasing the clamp on the baffle. The protective component will cover the laser head, thereby protecting the laser head after processing and preventing external force from damaging the laser head when idle.

[0021] (3) This application uses a cooling component to cool the laser-cut pipe. While the laser head is covered by the protective component, the cooling component itself will also be retracted. Thus, when idle, the cooling component is retracted for closed protection, which can help prevent external force from damaging the small fan equipment. Attached Figure Description

[0043] Example 1, see Figures 1-8This embodiment provides a laser cutting device for motorcycle pipe fittings, including a laser cutting machine body 1. An adjustment section 2 is provided on the top of the laser cutting machine body 1, and an adjustment seat 3 is provided on the outer surface of the adjustment section 2. The adjustment section 2 is part of the laser cutting machine body 1 and is used for X, Y, and Z axis adjustment, which is prior art. A laser head 4 is provided at the bottom of the adjustment seat 3, and the laser head 4 is used to emit a laser beam for cutting. A fixing component 5 is provided on the left side of the laser head 4, and the fixing component 5 is used to install the pipe fittings for cutting. The fixing component 5 includes a support base 501, which is fixedly connected to the top of the laser cutting machine body 1. A three-jaw chuck 502 is rotatably connected to the inner surface of the support base 501, and the three-jaw chuck 502 is connected to the support base 501. Equipped with a large bearing, a three-jaw chuck 502 is used to fix the pipe fitting. The rotation of the three-jaw chuck 502 on the inner surface of the support base 501 allows for the rotational adjustment of the fixed pipe fitting. A cylinder 503 is fixedly connected to the left side of the three-jaw chuck 502. The fixing assembly 5 also includes a motor 504, specifically a stepper motor. The output end of the motor 504 is fixedly connected to a worm gear 505 via a coupling. A support plate 506 is rotatably connected to the top of the worm gear 505. The support plate 506 is fixedly connected to the left side of the support base 501. A worm wheel 507 is rotatably connected to the back of the worm gear 505. The worm wheel 507 is fixedly connected to the outer surface of the cylinder 503. A blocking assembly 6 is provided on the right side of the laser head 4. The blocking assembly 6 includes a lifting frame 601. The lifting frame 601 is U-shaped. A placement seat 602 is fixedly connected to the bottom of the inner surface of the lifting frame 601. A groove is provided on the top of the placement seat 602 for placing a baffle 603. The baffle 603 is made of ceramic composite material and is used to resist the cutting of the laser beam. A cylinder 604 is fixedly connected to the top of the inner surface of the lifting frame 601. The cylinder 604 is in the extended state under normal conditions, with its output end facing downwards. A clamping plate 605 is fixedly connected to the output end of the cylinder 604. The clamping plate 605 presses down on the baffle 603 to fix it in the placement seat 602. The top of the clamping plate 605 is in frictional contact with the top of the baffle 603. An electric push rod 606 is fixedly connected to the top of the lifting frame 601. The output end of the electric push rod 606 faces downwards. The electric push rod 606 is used to push the lifting frame 601 up and down, thereby adjusting the relative position between the baffle 603 and the laser head 4. The electric push rod 606 is fixedly connected to the right side of the adjusting seat 3. A limit post 607 is fixedly connected to the top of the lifting frame 601. The limit post 607 is specifically a square rod. A limit frame 608 is slidably connected to the outer surface of the limit post 607. The limit frame 608 specifically includes a square-shaped sleeve and two U-shaped connecting rods. The limit frame 608 is fixedly connected to the outer surface of the adjusting seat 3. A protective component 7 is fitted to the outer surface of the laser head 4 for protection when idle. The protective component 7 protects the laser head 4 by the movement of the clamping plate 605 driven by the cylinder 604.Even without the baffle 603 inside the mounting base 602, its movement can still drive the protective component 7 to protect the laser head 4. This allows for easy adjustment of the protective component 7's switch during conventional through-type laser cutting. The front of the laser head 4 is equipped with a cooling component 8 for cooling the cut parts. The cooling component 8 provides air cooling for the laser-cut parts. When the protective component 7 covers the laser head 4, it also causes the cooling component 8 to retract and seal itself for protection.

[0044] In practical use, the aforementioned equipment first places the pipe to be cut into the three-jaw chuck 502 and fixes it in place. Then, the lifting frame 601 is raised or lowered by activating the electric push rod 606. The raising and lowering of the lifting frame 601 will drive the placement seat 602, thereby adjusting the relative position between the baffle 603 and the laser head 4 to accommodate the size of the pipe. At this time, the position of the adjusting seat 3 is adjusted by the adjusting part 2, so that the adjusting seat 3 moves the laser head 4 to the position on the upper surface of the pipe to be cut and the baffle 603 extends into the inner surface of the pipe. Then, the laser head 4 is activated to emit a laser beam to cut the pipe. During cutting, the adjusting part... The adjustment of the adjusting seat 3 and the laser head 4 is to facilitate the cutting of the required hollow shape. When the laser beam penetrates the upper surface of the tube, it will be blocked by the baffle 603, thus preventing the cutting of the bottom of the inner surface of the tube. This allows for the cutting of asymmetrical or rotationally symmetrical hollow shapes on the tube. After the cutting is completed, the adjustment of the adjusting seat 3 by the adjusting part 2 causes the laser head 4 and the baffle 603 to move away from the tube. At this time, the cylinder 604 is activated to pull the clamping plate 605 upward. The clamping plate 605 will release the clamping of the baffle 603, allowing the baffle 603 to be removed from the placement seat 602 for maintenance and replacement, thereby ensuring its blocking effect against the laser beam.

[0045] Example 2, see Figures 1-8The protective component 7 includes a first shield 701, which is annular in shape and fixedly connected to the bottom of the laser head 4. Specifically, the first shield 701 is connected to the bottom of a ring of protruding structures on the outer surface of the laser head 4. A second shield 702, also annular in shape, is slidably connected to the outer surface of the first shield 701 and fits over the outer surface of the first shield 701. A rotating rod 703 is rotatably connected to the bottom of the adjusting seat 3, and a limit ring 704 is rotatably connected to the outer surface of the rotating rod 703. The limit ring 704 is fixedly connected to the outer surface of the laser head 4. The positioning ring 704 is specifically connected to a protruding structure on the outer surface of the laser head 4. A baffle 705 is fixedly connected to the lower end of the rotating rod 703, which is used to block the bottom of the laser head 4. A guide post 706 is fixedly connected to the outer surface of the rotating rod 703. A guide groove 707 is formed on the outer surface of the guide post 706. The guide groove 707 is threaded and has a semi-circle on the outer surface of the guide post 706. A slider 708 is slidably connected to the outer surface of the guide post 706. The slider 708 is slidably connected to the inner surface of the guide groove 707. The guide post 706 drives the guide groove 707 to rotate 100 degrees. An 80-degree angle can move the slider 708 from one end to the other on its outer surface. The slider 708 is fixedly connected to the outer surface of the second baffle 702. A gear 709 is fixedly connected to the outer surface of the rotating rod 703. A rack 710 meshes with the outer surface of the gear 709. The rack 710 is slidably connected to the bottom of the adjusting seat 3. A slide rail is provided at the bottom of the adjusting seat 3 for the rack 710 to slide. The protective assembly 7 also includes a first hydraulic chamber 711. The first hydraulic chamber 711 is fixedly connected to the top of the inner surface of the lifting frame 601. A first hydraulic rod 71 is slidably connected to the inner surface of the first hydraulic chamber 711. 2. The first hydraulic rod 712 is fixedly connected to the top of the clamping plate 605. The bottom of the adjusting seat 3 is fixedly connected to the second hydraulic chamber 713. The second hydraulic chamber 713 and the first hydraulic chamber 711 are connected by pipelines. The second hydraulic chamber 713 and the first hydraulic chamber 711 are connected and communicated by hoses. Hydraulic oil is provided in the second hydraulic chamber 713 and the first hydraulic chamber 711. The volume of the second hydraulic chamber 713 is the same as that of the first hydraulic chamber 711. The second hydraulic rod 714 is slidably connected to the inner surface of the second hydraulic chamber 713. The second hydraulic rod 714 is fixedly connected to the rack 710.

[0046] In practical use, when the cylinder 604 pulls the clamping plate 605 upward, the upward movement of the clamping plate 605 also drives the first hydraulic rod 712 to rise on the inner surface of the first hydraulic chamber 711. At this time, the first hydraulic rod 712 pushes the hydraulic oil in the first hydraulic chamber 711 to be injected into the second hydraulic chamber 713 through the hose, thereby pushing the second hydraulic rod 714 to extend from the second hydraulic chamber 713. The second hydraulic rod 714 pushes the rack 710 to slide to the right, and the rack 710 will move the gear 709 to cause the rotating rod 703 to reverse within the limit ring 704. When the clockwise rotation is 180 degrees, the rotating rod 703 will cause the baffle 705 to rotate 180 degrees counterclockwise, blocking the area below the laser head 4. At the same time, as the rotating rod 703 rotates, it will also cause the guide post 706 to rotate 180 degrees counterclockwise. The rotation of the guide post 706 will cause the guide groove 707 to push the slider 708 down. The slider 708 will cause the second baffle 702 to slide down on the outer surface of the first baffle 701, thus completely covering the laser head 4 with the baffle 705, so as to provide sealed protection for the laser head 4 when not in use.

[0047] Example 3, see Figures 1-8 The cooling assembly 8 includes a protective box 801 with an open bottom. A cover 802 is hinged to the bottom of the protective box 801, and a counterweight 803 is fixedly connected to the front of the cover 802. Two limit plates 804 are slidably connected to the top of the protective box 801 and are slidably connected to the inner surface of the protective box 801. A lifting seat 805 is fixedly connected to the bottom of the limit plate 804. The lifting seat 805 is L-shaped, and a small fan device 806 is fixedly connected to the bottom of the lifting seat 805. The small fan device 806 includes a frame, fan blades, and a motor for driving the fan blades. The motor is electrically connected to an external power supply. The small fan device 806 is used to blow air onto the pipes to provide air cooling during laser cutting. The cooling assembly 8 also... The system includes a third hydraulic chamber 807, which is fixedly connected to the back of the adjusting seat 3. A third hydraulic rod 808 is slidably connected to the inner surface of the third hydraulic chamber 807. The third hydraulic rod 808 is L-shaped and fixedly connected to the back of the slider 708. A fourth hydraulic chamber 809 is fixedly connected through the top of the protective box 801. The fourth hydraulic chamber 809 is connected to the third hydraulic chamber 807 by pipelines and is connected and communicated with the third hydraulic chamber 807 by hoses. Hydraulic oil is provided in both the fourth hydraulic chamber 809 and the third hydraulic chamber 807. The volume of the fourth hydraulic chamber 809 is the same as that of the third hydraulic chamber 807. A fourth hydraulic rod 810 is slidably connected to the inner surface of the fourth hydraulic chamber 809 and is fixedly connected to the top of the lifting seat 805.

[0048] In practical use, the aforementioned equipment uses a small fan 806 to blow air and cool the cut pipe. When the second baffle 702 and baffle 705 cover the laser head 4 after processing, the descent of the slider 708 will also cause the third hydraulic rod 808 to descend within the third hydraulic chamber 807. At this time, the third hydraulic rod 808 will draw hydraulic oil from the fourth hydraulic chamber 809 through a hose, thereby causing the fourth hydraulic rod 810 to retract into the fourth hydraulic chamber 809. The fourth hydraulic rod 810 will pull the lifting seat 805 to raise the small fan 806, which will then rise into the protective box 801. As the small fan 806 rises, the baffle 802 loses its support, and the counterweight 803 will pull the baffle 802 upward under the action of gravity, covering the bottom of the protective box 801 and thus sealing the small fan 806 for protection when not in use.

[0049] In addition, this application also provides a method for laser cutting motorcycle pipe fittings, which uses the above-mentioned laser cutting device for motorcycle pipe fittings. The method includes the following steps:

[0050] S1. First, fix the pipe to be processed on the three-jaw chuck 502. Then, adjust the lifting frame 601 by the electric push rod 606 so that the relative height between the baffle 603 and the laser head 4 is adapted to the size of the pipe. At this time, adjust the height of the adjusting seat 3 and the X and Y axis positions by the adjusting part 2 so that the laser head 4 is above the pipe and the baffle 603 extends into the inner surface of the pipe.

[0051] S2. The laser beam emitted by the laser head 4 is used to cut the pipe. After the laser beam penetrates the upper surface of the pipe, it will be blocked by the baffle 603, so that it will not cut the bottom of the inner surface of the pipe, so as to cut out the hollow structure of asymmetric or rotationally symmetrical structure on the pipe.

[0052] S3. After the cutting is completed, the laser head 4 and the baffle 603 are moved away from the pipe by adjusting the adjusting seat 3 through the adjusting part 2. At this time, the cylinder 604 is activated to retract and drive the clamp 605 to move upward. The clamp 605 will release the baffle 603 from the fixation, so that the baffle 603 can be replaced or maintained after the processing is completed, thereby ensuring the baffle 603's blocking effect on the laser beam.

[0053] S4. When the clamp 605 removes the fixation of the baffle 603, it will also drive the protective component 7 to cover the laser head 4, thereby providing protection for the laser head 4 after processing.

[0054] S5. The cooling component 8 can be used to air-cool the pipe during the laser cutting process. When the protective component 7 covers the laser head 4, it will also drive the cooling component 8 to retract and seal it for storage, thereby protecting the cooling component 8 after processing.

[0055] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

8. A method for laser cutting motorcycle tubing, characterized in that, The method of use employs the motorcycle tubing laser cutting device as described in claim 7, and the method of use includes the following steps: S1. First, fix the pipe to be processed on the three-jaw chuck (502). Then, adjust the lifting frame (601) by the electric push rod (606) so that the relative height between the baffle (603) and the laser head (4) is adapted to the size of the pipe. At this time, adjust the height of the adjusting seat (3) and the X and Y axis positions by the adjusting part (2) so that the laser head (4) is above the pipe and the baffle (603) extends into the inner surface of the pipe. S2. The laser beam emitted by the laser head (4) is used to cut the pipe. After the laser beam penetrates the upper surface of the pipe, it will be blocked by the baffle (603), so that the bottom of the inner surface of the pipe will not be cut, so as to cut out the hollow of the asymmetric or rotationally symmetrical structure on the pipe. S3. After the cutting is completed, the laser head (4) and the baffle (603) are moved away from the pipe by adjusting the adjusting seat (3) through the adjusting part (2). At this time, the cylinder (604) is started to retract and drive the clamp (605) to move upward. The clamp (605) will release the baffle (603) so that the baffle (603) can be replaced or maintained after processing, thereby ensuring the baffle (603) has the effect of blocking the laser beam. S4. While the clamp (605) removes the fixation of the baffle (603), it will also drive the protective component (7) to cover the laser head (4), thereby providing protection for the laser head (4) after processing. S5. The cooling component (8) can be used to air-cool the pipe during the laser cutting process. When the protective component (7) covers the laser head (4), it will also drive the cooling component (8) to retract and seal it for storage, thereby protecting the cooling component (8) after processing.
