[0002] The tubular accessories of motorcycles mainly include carburetor fuel supply pipes, fuel tank fuel pipes, fuel pipes, etc. These tubular accessories are achieved through quantitative cutting during the production process, and the cutting is mainly achieved by laser cutting machines. The laser emitted from the laser is focused into a high-power density laser beam through the optical path system. The laser beam is irradiated to the surface of the workpiece, so that the workpiece reaches the melting point or boiling point to achieve shape transformation, and then the cutting is completed. However, there are still some problems in the use of existing laser cutting machines, as follows:

[0035] Compared with the prior art, the present application is provided with a support rod 66 that can be moved and retracted according to the size of the air pressure, and then the roller 69 is driven to move to clamp the tubular accessories, and the roller 69 can rotate in the direction of movement of the tubular accessories. In this way, when the pipeline movement position needs to be adjusted, the rotation of the roller 69 can be used to perform lateral position adjustment to ensure the effective determination of the cutting position. After the determination, the tubular parts can be clamped and positioned by the bellows 109 to increase the friction force. In this way, the pipeline can be rotated at a higher speed during the subsequent cutting process, thereby avoiding the metal slag generated during the cutting process from adhering to the incision to ensure the flatness of the incision. The air is supplied to the air inlet component 4 through an external air pressure control device, and the air pressure is adjusted to determine whether the force generated by the gas acts only on the guide control component 6 or on the guide control component 6 and the air guide component 10 at the same time, thereby producing different effects. Acting only on the guide control component 6 can ensure the basic clamping effect of the tubular accessories, ensuring their stability while allowing lateral movement, while acting on the guide control component 6 and the air guide component 10 at the same time can ensure that the tubular accessories can rotate stably without displacement during cutting, thereby ensuring the cutting effect, and the control method is simple, effective and responsive, which greatly improves the applicability of the structure.

[0036] See also Figure 1 and Fig. 9 A laser cutting machine for processing motorcycle tubular accessories includes a sealing ring 3, which is detachably installed and arranged, and is located at the position of the cutting notch 2 and is directly opposite to the center. The positions of the air intake component 4 and the inner ring 5 are correspondingly arranged, and the two are evenly arranged on the outer tube 1. The inner ring 5 is located on the outer tube 1 and has multiple through holes, and the air intake component 4 is correspondingly installed at the through holes;

[0037] In this embodiment, it should be noted that, during the cutting process, due to the rapid rotation cutting of the tubular fitting, the molten part produced during the cutting process will be centrifugally thrown out during rotation, and the thrown out metal will adhere to the sealing ring 3. Since there is no molten metal bonding at the cutting position of the fitting, the flatness of the cutting port is greatly guaranteed, and the sealing ring 3 can be disassembled for replacement and cleaning, thereby ensuring the applicability of the device.

[0038] See also Figure 1-2, a laser cutting machine for processing motorcycle tubular accessories, including a center ring 7, one side of the center ring 7 located outside the center ring 7 is fixedly connected to one end of a guide control component 6 through a connecting rod, a gear ring 8 is fixedly installed on the other side of the center ring 7 outside the center ring 7, a driving structure 12 is composed of an electric telescopic rod, a driving motor and a driving gear, the driving gear is vertically arranged between one side of the guide control component 6 and the gear ring 8, and can be staggered and meshed with the gear inside the guide control component 6 and the gear ring 8 respectively, a locking ring 11 is composed of a bottom ring and two centrally symmetrical vertical rods arranged thereon, and a slot for engaging with the guide control component 6 is opened on the vertical rod;

[0039] In the present embodiment, it should be noted that when it is necessary to drive the center ring 7 to rotate, the electric telescopic rod can be used to drive the driving gear to engage with the gear ring 8, thereby driving the center ring 7 and all the structures thereon to rotate, so that the rotary cutting of the tubular fittings can be achieved to avoid the molten metal from adhering to the incision and ensure the quality of the cutting. The driving gear can also use the external air pressure control device to make the top of the guide control component 6 bear against the tubular fitting and drive the internal structure of the guide control component 6 to rotate, so that the current pressing state can be locked through the cooperation of the guide control component 6 and the locking ring 11 to ensure the effect of the resistance clamping.

The air outlet hose 44 can be arranged corresponding to the through hole opened at the inner ring 5 and its size is larger than the size of the through hole.

When the gas is introduced into the air guide component 10 and it is necessary to exhaust, the center ring 7 can be rotated so that the original position center of the guide control component 6 can be rotated to the position of the push rod 43. In this way, the extension of the push rod 43 can open the end of the guide control component 6, and then the entire internal gas is depressurized to restore the structure for subsequent continuous use.

The two sides of the air intake sealing plate 62 are rotated by pins, and a coil spring is sleeved on the pins. The driven gear 64 is sleeved on the outside of the core rod 63 and rotated. An arc groove that passes through the bottom of the sleeve ring disk 65 is opened on the driven gear 64, and the position of the arc groove corresponds to the position of the locking ring 11. A plug-in plate that is centrally symmetrical and plugged into the locking ring 11 is arranged inside the sleeve ring disk 65. The limiting round rod 610 passes through the sleeve ring disk 65 for vertical limiting, and the support rod 66 is inserted into the adapter component 9 below. The support rod 66 is movably arranged, the top end of the support rod 66 is in contact with the gas guide component 10, the bottom end of the support rod 66 is rotatably arranged with the seat plate 67, and the middle part of the support rod 66 passes through the center ring 7 and is rotatably sleeved, so that when the gas is introduced into the internal structure of the gas guide component 10, the support rod 66 will be pushed downward when it expands, and its effective rebound can be guaranteed under the limiting action of the adapter component 9, and under the limiting action of the limiting round rod 610, when it is necessary to lock the sleeve ring disk 65 and the locking ring 11, the driven gear 64 is driven to rotate by the driving structure 12, and then the support rod 66 that moves downward can be driven to rotate through the limiting round rod 610, so that the two are locked to ensure the effective squeezing and clamping of the tubular accessories by the roller 69 to ensure the stability of the clamping.

[0044] See also Figure 4-5 , a laser cutting machine for processing motorcycle tubular accessories, comprising an adapter assembly 9, the adapter assembly 9 comprising an outer sleeve ring 91, and a spring 92 is fixedly installed inside the outer sleeve ring 91;

[0045] In this embodiment, it should be noted that the outer ring 91 is fixedly installed on the inner ring of the center ring 7, the size of the part of the support rod 66 located inside the outer ring 91 is smaller than the size of the external part, and the spring 92 is sleeved on the outside of the support rod 66, and the two ends are respectively set to contact the support rod 66 and the inside of the outer ring 91. In this way, during the downward movement of the support rod 66, it can be ensured that it will not move downward excessively and can automatically rebound. At the same time, the spring 92 also provides an effective force for stably clamping the tubular accessories.

[0046] See also Figure 3-9 A laser cutting machine for processing motorcycle tubular accessories, comprising an air guide assembly 10, the air guide assembly 10 comprising a central air intake ring 101 and an air guide outer ring 102, a resisting air pipe 103 is fixedly installed at the bottom end of the central air intake ring 101, an outer air guide pipe 104 is fixedly installed on the outer side of the air guide outer ring 102, an air chamber 105 is fixedly installed at the bottom end of the outer air guide pipe 104, an inner air guide pipe 106 is fixedly installed at the bottom end of the air chamber 105, a partition 107 is fixedly installed at the middle part of the inner part of the air chamber 105, two one-way valves 108 are movably installed on the partition 107, the bottom end of the inner air guide pipe 106 passes through the side plate 68 and a bellows 109 is fixedly installed at the bottom end thereof;

[0047] In the present embodiment, it should be noted that the top ends of the central air intake ring 101 and the air guide outer ring 102 are both connected to the inside of the top plate 61, the central air intake ring 101 is arranged on the inner side, and the bottom end of the air pipe 103 is arranged to be in contact with the top end of the support rod 66, the partition 107 divides the inside of the air chamber 105 into two relatively sealed spaces, the two one-way guide valves 108 are respectively arranged on the partition 107 to be able to be opened by unidirectional rotation in opposite directions, and a rotatable baffle is arranged on one side of the partition 107 that is rotated to open in the direction of the inner air pipe 106, and the two ends of the baffle are installed by a pin shaft arranged with a reset coil spring, and the driving rotational force of the reset coil spring is greater than the maximum deformation of the air pipe 103 and the spring 92. The sum of the large driving forces, so that when it is necessary to perform rotational cutting on the tubular accessories, it is only necessary to increase the air pressure to rotate and open a one-way valve 108, and the gas enters the inner air guide tube 106 and then inflates the bellows 109, and then contacts and clamps the surface of the tubular accessories, so that the maximum clamping effect can be ensured without damaging the accessories, and the effect of rotational cutting can be achieved. When it is necessary to remove this force, it is only necessary to rotate the center ring 7 so that the push rod 43 is aligned with the air inlet sealing plate 62 and gas is introduced into the air guide ring 41 so that the push rod 43 is extended to press the air inlet sealing plate 62 and then open the channel there, so that the pressure inside the air guide assembly 10 can be relieved, and then the accessories can be contacted and clamped, which is convenient for the subsequent movement of the tubular accessories.

[0048] Working principle: insert the tubular fitting into the middle of the center ring 7, and then start the external air pressure control device to introduce gas into the air guide ring 41. By controlling the air pressure, the resisting air pipe 103 expands, which will push the support rod 66 downward. Under the limiting effect of the adapter component 9, it can ensure its effective rebound, and under the limiting effect of the limiting round rod 610, it can be ensured that when it is necessary to lock the sleeve ring disk 65 and the locking ring 11, the driven gear 64 is driven to rotate by the driving structure 12, and then the supporting rod 66 moving downward can be driven to rotate through the limiting round rod 610, so that the two are locked to ensure that the roller 69 effectively squeezes and clamps the tubular fitting, thereby realizing the preliminary positioning and clamping of the tubular fitting. When rotational cutting is required, the air pressure input is increased to allow the gas to pass through the air guide outer ring 102 and enter the outer air guide pipe 104, and then a one-way valve 10 is made. 8 is rotated to open, and the gas enters the inner air guide tube 106 and then inflates the bellows 109, and then contacts the surface of the tubular accessory to clamp it, and then the driving motor in the driving structure 12 is started to drive the driving gear to rotate, and the electric push rod in the driving structure 12 will also be started so that the driving gear first engages with the driven gear 64, so that the driven gear 64 that has moved down to the corresponding position is driven by the sleeve ring disk 65 to rotate and snap into the slot on the locking ring 11 to be locked, and then the telescopic control driving gear is engaged with the gear ring 8 to drive the center ring 7 and the tubular accessory to rotate and cut, and after the cutting is completed, the air inlet sealing plate 62 is rotated to align with the push rod 43, and air is supplied to the air guide ring 41 again so that the push rod 43 extends to push the air inlet sealing plate 62 to release the pressure inside the air guide component 10, so as to release the clamping of the tubular accessory, and then the cut accessory is taken out and the above operation is repeated.
