Through precision machining, they are made into frame linkages and landing gear support shafts to ensure that the airframe achieves a balance between load-bearing capacity and impact resistance. The excellent durability of this material ultimately significantly improves the reliability and service life of UAVs in complex environments. Chinese patent application number 202422168616.1 discloses a stainless steel bar length-cutting device, relating to the field of cutting technology. This device includes a lifting plate; a transmission wheel is connected to a bearing seat on the lifting plate, and the shaft of the transmission wheel is connected to a second drive motor; a measuring device is provided on one side of the transmission wheel and is fixed to the lifting plate by bolts; a support frame is provided on one side of the lifting plate, the support frame being V-shaped, and a rotating roller is provided inside the support frame; a laser cutting machine is positioned above the lifting plate. When cutting hollow stainless steel bars used on drones, laser cutting equipment is used. In the field of laser metal cutting technology, the metal particles generated by laser cutting will enter the hollow part of the stainless steel bar through the cutting gap. During the flight of the drone, the metal particles will roll and collide in the inner cavity of the bar as the attitude changes, which will disrupt the overall dynamic balance of the drone. Therefore, after the cutting is completed, the metal particles that have entered need to be cleaned. The cleaning process will take up processing time and slow down the processing efficiency of the stainless steel bar. Summary of the Invention

[0014] This invention provides a device for cutting stainless steel bars to a fixed length. It has the following advantages: 1. This stainless steel bar length-cutting device can improve the technical problems in the field of "laser metal cutting". By rotating the first spiral blade, air is pushed to flow inside the hollow stainless steel bar, which cools the hollow stainless steel bar being cut and pushes the metal particles in the cavity to the left into the receiving box. This reduces the metal particles generated inside the hollow stainless steel bar during cutting, reduces the processing steps of the hollow stainless steel bar after cutting, and thus improves the processing efficiency of hollow stainless steel bars.

[0015] 2. This stainless steel bar length-cutting device can improve the technical problems in the field of "laser metal cutting". By pushing air through the hollow stainless steel bar into the receiving box through the first spiral blade, the air is then pushed back into the hollow stainless steel bar, causing the airflow to circulate. The oxygen in the circulating air gradually decreases, thereby reducing the reaction between the hollow stainless steel bar and oxygen when cutting multiple times, thus improving the cutting quality, reducing the workload of the cut surface, and improving the processing efficiency of hollow stainless steel bars.

[0016] 3. This stainless steel bar length-cutting device can improve the technical problems in the field of "laser metal cutting". In laser cutting, the circulating gas is heated. When cutting a new hollow stainless steel bar, the airflow will transfer the residual heat to the hollow stainless steel bar. This can preheat the hollow stainless steel bar while reducing the temperature of the circulating gas. Preheating can reduce the stress deformation caused by the sudden temperature change during cutting, thereby improving the product qualification rate and indirectly improving the processing efficiency of hollow stainless steel bars.

[0017] 4. This stainless steel bar length-cutting device can improve the technical problems in the field of "laser metal cutting". By allowing the hollow stainless steel bar to gradually pass through the inside of the rotating cylinder, the surface is brushed by the spiral brush plate, and the impurities on the surface of the hollow stainless steel bar are pushed to the right. The impurities attached to the surface of the hollow stainless steel bar are cleaned and collected, avoiding the drying effect of impurities on the laser cutting effect of the hollow stainless steel bar. It reduces the subsequent processing steps and can improve the processing efficiency of hollow stainless steel bars.

[0018] 5. This stainless steel bar length-cutting device can improve the technical problems in the field of "laser metal cutting". By using a rolling wheel to apply organic solvent to the surface of the hollow stainless steel bar, the organic solvent is evenly applied to the surface of the hollow stainless steel bar when the spiral brush plate rotates. The brushing action cleans the oil stains on the surface of the hollow stainless steel bar, avoiding the influence of residual oil stains on the surface of the hollow stainless steel bar on laser cutting, and improving the processing efficiency of hollow stainless steel bars.

[0019] 6. This stainless steel bar length-cutting device utilizes the airflow generated by the rotation of the second spiral plate to remove organic solvents from the surface of the hollow stainless steel bar. Simultaneously, the first spiral blades push a hot airflow with residual heat. This airflow passes through the inner cavity of the hollow stainless steel bar, slightly heating it and accelerating the drying of liquids on its surface. This improves the efficiency of cleaning the hollow stainless steel bar and thus enhances the processing efficiency of the hollow stainless steel bar.

[0020] 7. The stainless steel bar length cutting device rotates the striking plate 807, causing it to continuously strike the surface of the hollow stainless steel bar, resulting in vibration that promotes the removal of impurities from the surface. Simultaneously, after cutting, the vibration causes internal metal particles to fall from the inner wall of the hollow stainless steel bar, further improving the processing effect on the inner cavity and thus increasing the processing efficiency of the hollow stainless steel bar.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0025] Example 1: Please refer to Figure 1-9 The present invention provides a technical solution: a stainless steel bar length-cutting device, including a support platform 1, a control center 2 fixedly connected to the top of the support platform 1, a positioning component 3 fixedly connected to the top of the support platform 1 on the left side of the control center 2, a laser head 4 fixedly connected to the front of the positioning component 3, a fixing component 5 fixedly connected to the top of the support platform 1 at the bottom of the control center 2, a cooling mechanism 6 fixedly connected to the top of the support platform 1 on the left side of the laser head 4, a cleaning mechanism 7 fixedly connected to the top of the support platform 1 on the right side of the laser head 4, and an auxiliary mechanism 8 fixedly connected to the top of the support platform 1 on the right side of the cleaning mechanism 7. The fixing component 5 is equipped with a rotatable three-grip chuck. After a hollow stainless steel bar is passed through the center of the fixing component 5, the hollow stainless steel bar can be fixed by the corresponding three-grip chuck, and the hollow stainless steel bar can be rotated by the three-grip chuck. Cooling mechanism 6 includes: The connector 602 is located on the top of the support platform 1, to the left of the laser head 4. The feed tube 607 is located on the top of the support platform 1, to the right of the laser head 4. Receiver box 603 is fixedly connected to the left side of terminal tube 602.

[0026] After the hollow stainless steel bar is fixed by the three-grip chuck, the positioning component 3 can move the position of the laser head 4, so that the positioning component 3 controls the laser head 4 to move to the corresponding position to cut the hollow stainless steel bar. At the same time, the three-grip chuck of the fixing component 5 drives the hollow stainless steel bar to rotate, so that the laser head 4 rotates and cuts the hollow stainless steel bar.

[0027] A first driving block 601 is fixedly connected to the bottom of the connector tube 602. A guide rail that cooperates with the first driving block 601 is provided on the top of the support platform 1. A baffle plate 606 is movably connected inside the receiver box 603 at the corresponding position of the connector tube 602. A collecting bottom 604 is movably connected to the receiver box 603. A buckle that cooperates with the collecting bottom 604 is provided at the bottom of the receiver box 603. The collecting bottom 604 is movably connected to the receiver box 603 through the buckle. When there is an airflow to the left inside the connector tube 602, the baffle plate 606 can be pushed open. When an airflow to the right is generated, the baffle plate 606 will adhere to the inner wall of the receiver box 603, sealing the connection between the receiver box 603 and the connector tube 602, and preventing metal particles that have entered the receiver box 603 from accidentally flowing out.

[0028] The back of the feeding tube 607 is fixedly connected to a second drive block 608. The outer wall of the control center 2 is provided with a guide rail that cooperates with the second drive block 608. The inside of the feeding tube 607 is fixedly connected to a first motor 609. The inside of the feeding tube 607 is provided with a first spiral blade 610. The first spiral blade 610 is fixedly connected to the output shaft of the first motor 609.

[0029] The second drive block 608 moves the feeding tube 607 upward along the corresponding guide rail, then passes the hollow stainless steel bar through the center of the three-jaw chuck of the fixing component 5, so that the right end of the hollow stainless steel bar is on the left side of the feeding tube 607. Then, the second drive block 608 moves the feeding tube 607 downward, so that the feeding tube 607 is on the right side of the hollow stainless steel bar. Next, the first drive block 601 moves the receiving tube 602 along the corresponding guide rail, so that the left end of the receiving tube 602 is in contact with the hollow stainless steel bar, and pushes the hollow stainless steel bar to the right until the right end of the hollow stainless steel bar is in contact with the feeding tube 607, allowing the control center 2 to measure the length of the hollow stainless steel bar. Then, the three-jaw chuck on the fixing component 5 clamps the hollow stainless steel bar, aligning the hollow hole inside the hollow stainless steel bar with the receiving tube 602 and the feeding tube 607. The positioning component 3 moves the position of the laser head 4. The control center 2 controls the positioning component 3 to make the laser head 4 reach the corresponding position, ensuring that the horizontal distance between the laser head 4 and the left end of the feeding tube 607 is the required cutting value, so as to cut the hollow stainless steel bar to a fixed length.

[0030] The three-grip chuck on the fixed component 5 drives the hollow stainless steel bar to rotate and causes the laser head 4 to cut it. At the same time, the first motor 609 inside the feed tube 607 drives the first spiral blade 610 to rotate, pushing the air to the left. This causes the air inside the hollow stainless steel bar to flow to the left, which cools the cut hollow stainless steel bar. At the same time, the air pushes the metal particles that have entered the cavity to the left. The airflow pushes open the baffle plate 606, allowing the metal particles to enter the receiving box 603. The airflow inside the receiving box 603 will be discharged upward, causing the metal particles that have entered the receiving box 603 to fall into the collecting bottom 604 under the action of gravity. When the collecting bottom 604 has accumulated too much, the collecting bottom 604 can be removed from the bottom of the receiving box 603 to process the collected metal particles, which facilitates the recycling of waste materials.

[0031] During cutting, the flowing air brings oxygen, which reacts with the hollow stainless steel bar. Reducing the oxygen during cutting minimizes the chemical reaction between the hollow stainless steel bar and oxygen, resulting in a smoother cut surface, improved processing quality, and fewer subsequent processing steps. An L-shaped tube 611 is fixedly connected to the right side of the feed tube 607. An electric telescopic rod 612 is fixedly connected to the top of the L-shaped tube 611. The top of the electric telescopic rod 612 is fixedly connected to the back side of the control center 2. A connecting tube 613 is fixedly connected to the top of the L-shaped tube 611. A moving tube 614 is fixedly connected to the bottom of the connecting tube 613. An expansion plate 615 is fixedly connected to the bottom of the moving tube 614. The expansion plate 615 is movably connected inside the receiving box 603 and is located on top of the barrier plate 606. Several heat dissipation plates 605 are fixedly connected to the outer wall of the receiving box 603. When the feeding tube 607 is moved by the second drive block 608, the electric telescopic rod 612 will extend and retract in coordination with the movement of the second drive block 608, so that the L-shaped tube 611 and the feeding tube 607 move up and down synchronously.

[0032] The air pushed into the receiving box 603 flows into the connecting pipe 613 through the moving pipe 614, and then enters the back of the feeding pipe 607 through the L-shaped pipe 611. It is then pushed again by the first spiral blade 610 into the hollow stainless steel bar, causing the airflow to circulate. During the flow, this part of the oxygen is gradually consumed, reducing the oxygen in the circulating air. This reduces the reaction between the hollow stainless steel bar and oxygen when making multiple cuts, thereby improving the cutting quality and reducing the workload of processing the cut surface.

[0033] Furthermore, the circulating gas expands due to heat, causing the gas passing through the cutting position to expand as well. This increases the internal pressure of the receiving box 603, pushing the expansion plate 615 upwards and reducing the possibility of gas overflow due to expansion. The heated gas transfers heat to the heat dissipation plate 605 inside the receiving box 603, thus dissipating heat and maintaining a good cooling effect during continuous processing. Simultaneously, when cutting new hollow stainless steel bars, the airflow passing through the hollow stainless steel bars transfers residual heat to them, preheating the bars and reducing the temperature of the circulating gas. This preheating reduces the stress deformation caused by sudden temperature changes during cutting, thereby improving the product processing qualification rate.

[0034] Example 2: Please refer to Figure 1-10 Based on Embodiment 1, the present invention provides a technical solution: During the production process, some metal debris will adhere to the surface of hollow stainless steel bars, resulting in impurities on the surface during laser cutting. When exposed to the high temperature of the laser, these impurities will burn, vaporize, or melt irregularly, interfering with the normal flow of molten metal. This leads to problems such as roughness, burrs, and slag on the cut surface, affecting the cutting quality, increasing the number of subsequent processing steps, and thus reducing the processing efficiency of hollow stainless steel bars.

[0035] The cleaning mechanism 7 includes a support frame 701, which is fixedly connected to the left side of the control center 2. A rotating cylinder 702 is movably connected to the bottom of the support frame 701, and a spiral brush plate 705 is fixedly connected inside the rotating cylinder 702.

[0036] The support frame 701 is internally fixedly connected to a second motor 703, and the output shaft on the left side of the support frame 701 is fixedly connected to a drive tooth 704. The outer wall of the spiral brush plate 705 is provided with teeth that mesh with the drive tooth 704.

[0037] When the hollow stainless steel rod is passed through the fixing component 5, it will gradually pass through the inside of the rotating cylinder 702. At the same time, the second motor 703 drives the rotating cylinder 702 to rotate through the drive gear 704, causing the spiral brush plate 705 to rotate on the surface of the hollow stainless steel rod, brushing the hollow stainless steel rod and pushing the impurities on the surface of the hollow stainless steel rod to the right, thus cleaning the impurities attached to the surface of the hollow stainless steel rod.

[0038] Impurities need to be collected after cleaning to prevent them from accumulating in the processing area. A movable cover 706 is fixedly connected to the bottom of the laser head 4. A fixed cover 707 is fixedly connected to the top of the support platform 1 at the bottom of the movable cover 706. A connecting cylinder 708 is fixedly connected to the bottom of the fixed cover 707 at the bottom of the support platform 1. The bottom of the fixed cover 707 and the connecting cylinder 708 are interconnected. A collecting cylinder 709 is fixedly connected to the bottom of the connecting cylinder 708 by bolts. The collecting cylinder 709 and the connecting cylinder 708 are detachable.

[0039] An isolation trough plate 711 is fixedly connected to the bottom of the collection cylinder 709. A separation net 710 is fixedly connected to the top of the isolation trough plate 711. A third motor 712 is fixedly connected to the bottom of the isolation trough plate 711. A second spiral plate 713 is fixedly connected to the top of the third motor 712 and the top of the second spiral plate 713. A sweeping plate 714 is provided on the top of the separation net 710 and is fixedly connected to the second spiral plate 713 through the separation net 710.

[0040] During cleaning, the third motor 712 is started, causing the second spiral plate 713 to rotate. This generates an airflow at the top of the connecting cylinder 708. The spiral brush 705 pushes the swept-down impurities to the left. The airflow generated by the rotation of the second spiral plate 713 draws the impurities swept down by the spiral brush 705 into the collection cylinder 709. The impurities adhere to the top of the separating net 710 with the airflow, thus collecting them and preventing them from splashing everywhere. At the same time, the sweeping plate 714 is rotated along with the second spiral plate 713, sweeping the impurities into the groove of the isolation plate 711, preventing impurities from accumulating on the top of the separating net 710 and affecting the airflow.

[0041] In addition, during laser cutting, the movable cover 706 will move the laser head 4 to offset the crack from the fixed cover 707. The airflow generated by the second spiral plate 713 will suck the metal particles that are splashed during cutting into the collection cylinder 709 for collection, preventing the splashed metal particles from scattering everywhere. When too many impurities are collected inside the collection cylinder 709, the collection cylinder 709 can be removed from the bottom of the connecting cylinder 708 to process the collected material inside the collection cylinder 709.

[0042] Example 3: Please refer to Figure 1-12 Based on Embodiment 1 and Embodiment 2, the present invention provides a technical solution: The surface of hollow stainless steel bars may have some oil stains due to processing. When the laser irradiates the oil stains, the oil stains will burn violently under the high temperature of the laser, which will cause a large amount of hard-to-remove slag to form at the bottom of the cut, and make the cut surface rough and affect the cutting quality.

[0043] The auxiliary mechanism 8 includes a third drive block 801, which is movably connected to the left side of the control center 2. The outer wall of the control center 2 is provided with a guide rail that cooperates with the third drive block 801. A container box 802 is fixedly connected to the left side of the third drive block 801. A branch pipe 803 is provided on the back of the container box 802. A rolling wheel 804 is movably connected to the back of the branch pipe 803. The rolling wheel 804 is filled with an organic solvent for cleaning oil stains. Several discharge holes 805 are opened on the outer wall of the rolling wheel 804.

[0044] The third drive block 801 pushes the container box 802 backward along the corresponding track, causing the hollow stainless steel rod to pass through the fixed component 5. This brings the outer wall of the hollow stainless steel rod into contact with the outer wall of the rolling wheel 804, causing the rolling wheel 804 to rotate. As the rolling wheel 804 rotates, the organic solvent inside the branch pipe 803 is applied to the surface of the hollow stainless steel rod through the discharge hole 805. As the hollow stainless steel rod moves, it is carried into the rotating cylinder 702, where the spiral brush plate 705 evenly applies the organic solvent to the surface of the hollow stainless steel rod during rotation. Afterward, the hollow stainless steel rod is pulled out and returned to its original position, enabling... The spiral brush 705 removes oil stains from the surface of the cut portion of the hollow stainless steel bar, achieving rapid cleaning of the oil stains on the cut portion. Subsequently, the airflow generated by the rotation of the second spiral plate 713 promotes the evaporation of organic solvents on the surface of the hollow stainless steel bar. At the same time, the first spiral blade 610 pushes a hot airflow with residual heat. The airflow flows through the inner cavity of the hollow stainless steel bar, which can slightly heat the hollow stainless steel bar, promote the drying of liquids on the surface of the hollow stainless steel bar, and improve the cleaning efficiency of the hollow stainless steel bar. At the same time, the heat absorbed by the solvent evaporation can cool the airflow, further improving the cooling effect of the circulating gas.

[0045] The top of the support platform 1 is fixedly connected to the fourth motor 806 on the left side of the fixed component 5. The fourth motor 806 has a striking piece 807 on its left side, and the striking piece 807 is fixedly connected to the output shaft of the fourth motor 806. The striking piece 807 is made of rubber to prevent the striking piece 807 from damaging the surface shape of the hollow stainless steel bar when it impacts the hollow stainless steel bar.

[0046] As the hollow stainless steel bar moves to the left, the fourth motor 806 drives the striking plate 807 to rotate, causing the striking plate 807 to continuously strike the surface of the hollow stainless steel bar, making the hollow stainless steel bar vibrate. The vibration can promote the removal of impurities from the surface of the hollow stainless steel bar. At the same time, after the cutting is completed, striking the hollow stainless steel bar can shake off the metal particles inside the hollow stainless steel bar from the inner wall, further improving the processing effect on the inner cavity of the hollow stainless steel bar.

[0047] 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.
