Description

Technical Field

[0001] This invention relates to the field of laser beam processing technology, and in particular to a sheet metal cutting machine for mechanical equipment processing and manufacturing based on a high-energy laser beam. Background Technology

[0002] High-energy laser beam cutting machines use an optical system to guide and focus a laser beam onto the material surface, forming an extremely small spot, enabling high-precision cutting. In sheet metal processing, they can perform diverse operations such as surface etching, marking, and cutting / separation.

[0003] Laser processing utilizes a bed of nails to support the sheet metal. When processing multiple sheets of the same specification consecutively, the fixtures on the bed of nails hold and position the sheet metal, reducing the time required for sensor alignment and thus improving processing efficiency. However, existing bed of nail fixtures have significant drawbacks when centering the sheet metal: when manually moving the sheet metal on the bed of nails for centering, the lower surface of the sheet metal is prone to scratching against the support nails. This not only causes surface wear, affecting product appearance, but for precision sheets (such as mirror steel plates and coated sheets), even minor scratches can lead to performance degradation or complete scrapping. Furthermore, debris generated from scratching adheres to the gaps in the bed of nails, accumulating over time and affecting the flatness of subsequent sheets, leading to positioning accuracy deviations. Moreover, frequent adjustments to the force required during manual movement to avoid excessive scratching increase operation time and diminish the processing efficiency that the fixture is meant to improve. Summary of the Invention

[0004] Given that existing technologies can easily scratch sheet metal when positioning and adjusting it, a sheet metal cutting machine based on a high-energy laser beam for mechanical equipment processing and manufacturing is proposed.

[0005] Its purpose is to: when the telescopic cylinder rises and retracts, it discharges air, forming an air film between the cylinder and the board. At the same time, the positioning block pushes the board to adjust its position. Then, when the telescopic cylinder descends and retracts, it creates negative pressure to adsorb and fix the board.

[0006] The technical solution of the present invention is a sheet metal cutting machine for mechanical equipment processing and manufacturing based on a high-energy laser beam, including a frame, a nail bed and a laser cutter, and also including multiple connecting seats installed on the inner wall of the frame. A support frame is fixedly connected to the top surface of the connecting seat. A telescopic cylinder and a positioning block are slidably connected on the support frame. A driving component is installed on the support frame. When the driving component rises, it drives the telescopic cylinder to retract and drives the positioning block to push the sheet metal.

[0007] The telescopic cylinder includes a fixed cylinder that slides with the support frame, a telescopic sleeve is fixedly connected to the bottom of the fixed cylinder, a sealing cylinder is fixedly connected to the bottom of the telescopic sleeve, and multiple elastic elements are connected between the fixed cylinder and the sealing cylinder.

[0008] The driving component includes two electric push rods fixedly installed with the connecting seat. The upper ends of the electric push rods movably pass through the connecting seat, and a lifting frame is fixedly connected between the upper ends of the two electric push rods. When the electric push rods extend, they drive the lifting frame to rise. The telescopic cylinder rises and contacts the bottom surface of the sheet material and releases air. The positioning block pushes the sheet material to center its position. When the electric push rods descend, the elastic element drives the telescopic cylinder to return to its original position and adsorb and fix the sheet material.

[0009] Furthermore, the plurality of connecting seats are arranged in a rectangular structure, and the plurality of connecting seats are respectively fixedly installed on the inner walls of opposite sides of the frame.

[0010] Furthermore, the support frame includes two fixed plates that are fixedly connected to the connecting seat, and two guide rails are fixedly connected between the two fixed plates;

[0011] The outer wall of the fixed cylinder is slidably sleeved with a limiting ring, and the outer wall of the limiting ring is fixedly connected with two sliding sleeves, which are slidably sleeved on the corresponding guide rails.

[0012] Furthermore, the lower part of the positioning block has multiple oblique holes, a fixed rod is slidably connected in the oblique holes, a second sliding sleeve is slidably sleeved on the guide rail, and the end of the fixed rod is connected and fixed to the corresponding second sliding sleeve.

[0013] Furthermore, two sliding sleeves are slidably sleeved on the lifting frame, and a drive ring is fixedly connected between the two sliding sleeves. The drive ring is slidably sleeved on the outer wall of the sealing cylinder.

[0014] A U-shaped seat is slidably sleeved on the lifting frame, and the U-shaped seat is located below the positioning block.

[0015] Furthermore, the multiple elastic elements are arranged in a ring at equal intervals. Each elastic element includes a guide rod that is fixedly connected to the lower part of the outer wall of the fixed cylinder. The lower end of the guide rod movably penetrates the upper part of the outer wall of the sealing cylinder, and a compression spring is sleeved on the outer wall of the guide rod. The two ends of the compression spring are respectively connected to the fixed cylinder and the sealing cylinder.

[0016] Furthermore, the top surface of the guide rail is provided with a toothed groove, and the top surface of the inner wall of the first sliding sleeve and the top surface of the inner wall of the second sliding sleeve are both fixed with positioning protrusions, which engage with the toothed grooves.

[0017] Furthermore, a sealing ring is fixedly installed on the inner wall of the sealing cylinder, and a through hole adapted to the sealing ring is opened on the sealing cylinder. A sealing plate is abutted and fitted inside the sealing ring, and a spring hinge is connected between the sealing plate and the sealing ring.

[0018] Furthermore, a trapezoidal block is fixedly connected to the side of the sealing plate facing the through hole. One end of the inclined surface of the trapezoidal block extends to the outside of the sealing cylinder. An L-shaped rod is vertically slidably connected inside the trapezoidal block. The lower end of the L-shaped rod abuts against the outer wall of the sealing cylinder. A rotating rod is rotatably connected inside one end of the inclined surface of the trapezoidal block. One end of the rotating rod slides in contact with the L-shaped rod.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By raising and compressing the telescopic cylinder, the sheet metal is first lifted off the nail bed. Then, as air is expelled from the cylinder, an air film forms between the cylinder and the sheet metal, keeping the sheet metal suspended. Simultaneously, multiple fixing blocks work together to push the sheet metal, keeping it centered. When the telescopic cylinder descends and returns to its original position, the negative pressure generated inside attracts the sheet metal and stably positions it on the nail bed. This achieves non-destructive orientation adjustment and automatic fixing of the sheet metal, simplifies the positioning process, and improves processing efficiency.

[0021] 2. Under its own weight, the L-shaped rod abuts against the outer wall of the sealing cylinder, limiting the contact between the sealing plate and the sealing ring and ensuring the stability of the negative pressure adsorption. When the drive ring descends, it will drive the L-shaped rod to rise, causing the sealing plate to rotate. The telescopic cylinder will then automatically release the negative pressure adsorption on the plate, making it easy to pick up and put down the plate.

[0022] 3. The sliding adjustment of sliding sleeve one, sliding sleeve two and guide rail allows the telescopic cylinder and positioning block to be adapted and adjusted according to the size and cutting direction of the sheet material, better adapting to the processing needs of different sheet materials, and improving the applicability of the equipment and the reliability of processing.

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Example 1, referring to Figures 1-6 This invention provides a sheet metal cutting machine for mechanical equipment processing and manufacturing based on a high-energy laser beam, including a frame 1, a nail bed 2, and a laser cutter 3. It also includes multiple connecting seats 4 installed on the inner wall of the frame 1. A support frame 5 is fixedly connected to the top surface of each connecting seat 4. A telescopic cylinder 6 and a positioning block 8 are slidably connected to the support frame 5. A driving component 14 is installed on the support frame 5. When the driving component 14 rises, it causes the telescopic cylinder 6 to retract and the positioning block 8 to push the sheet metal. The telescopic cylinder 6 includes a fixed cylinder 61 that slidably engages with the support frame 5. A telescopic sleeve 62 is fixedly connected to the bottom of the fixed cylinder 61. A sealing cylinder 63 is fixedly connected to the bottom of sleeve 62, and multiple elastic elements 7 are connected between the fixed cylinder 61 and the sealing cylinder 63. The driving component 14 includes two electric push rods 141 fixedly installed with the connecting seat 4. The upper end of the electric push rod 141 moves through the connecting seat 4, and a lifting frame 142 is fixedly connected between the upper ends of the two electric push rods 141. When the electric push rod 141 extends, it drives the lifting frame 142 to rise. The telescopic cylinder 6 rises and contacts the bottom surface of the plate and discharges air. The positioning block 8 pushes the plate to position it in the center. When the electric push rod 141 descends, the elastic elements 7 drive the telescopic cylinder 6 to return to its original position and adsorb and fix the plate.

[0035] Specifically, the electric push rod 141 drives the lifting frame 142 to move up and down. When the lifting frame 142 rises, it drives the telescopic cylinder 6 to rise as well. After the top surface of the telescopic cylinder 6 contacts the bottom surface of the sheet metal, it continues to drive the sheet metal upward, causing it to detach from the nail bed 2. Then, the telescopic sleeve 62 is compressed, reducing the internal space of the telescopic cylinder 6, and the internal air is discharged through the upper port of the fixed cylinder 61. At this time, an air film is formed between the upper port of the fixed cylinder 61 and the bottom surface of the sheet metal, keeping the sheet metal in a suspended state. At the same time, the lifting frame 142 drives the positioning blocks 8 to move. Multiple positioning blocks 8 cooperate with each other to push the suspended sheet metal, keeping it centered. Subsequently, when the electric push rod 141 drives the lifting frame 142 to descend, the elastic element 7 drives the telescopic sleeve 62 to reset, increasing the space inside the telescopic cylinder 6 while keeping the air volume unchanged, thereby generating negative pressure. This pressure then adsorbs and fixes the positioned sheet metal, allowing it to be placed stably on the nail bed 2, creating favorable conditions for the subsequent precise cutting of the sheet metal by the laser cutter 3.

[0036] This design allows the sheet material to be positioned while suspended, avoiding direct contact and scratching with the nail bed 2 and protecting the sheet material surface. The combination of air film and negative pressure adsorption makes the sheet material positioning more accurate and the fixation more stable, effectively improving the precision and efficiency of laser cutting.

[0037] Reference Figure 1 Multiple connectors 4 are arranged in a rectangular structure, and multiple connectors 4 are fixedly installed on the inner walls of opposite sides of the frame 1.

[0038] Specifically, the support frame 5, telescopic cylinder 6, and positioning block 8 form a symmetrical layout. When positioning the sheet metal, the positioning blocks 8 on both sides can apply force simultaneously from opposite sides of the sheet metal, making the force on the sheet metal more balanced and avoiding sheet metal displacement due to force on one side, thereby improving the accuracy of centering positioning. At the same time, the telescopic cylinders 6 on both sides can provide uniform support and suction force from below the sheet metal, making the sheet metal more firmly fixed and further ensuring the accuracy and stability of subsequent laser cutting.

[0039] Reference Figure 5 The support frame 5 includes two fixed plates 51 that are fixedly connected to the connecting seat 4. The two fixed plates 51 are fixedly connected to two guide rails 52. The outer wall of the fixed cylinder 61 is slidably sleeved with a limit ring 9. The outer wall of the limit ring 9 is fixedly connected with two sliding sleeves 10. The sliding sleeves 10 are slidably sleeved on the corresponding guide rails 52.

[0040] Specifically, the sliding sleeve 10 can slide smoothly in a straight line on the guide rail 52, thereby driving the telescopic cylinder 6 to adjust its horizontal position. This design allows the telescopic cylinder 6 to flexibly change its position according to the actual cutting orientation. The cooperation between the sliding sleeve 10 and the guide rail 52 ensures the stability and accuracy of the telescopic cylinder 6 during horizontal adjustment, avoiding deviation during the adjustment process. Flexibly adjusting the position of the telescopic cylinder 6 according to the cutting orientation better adapts to the processing requirements of different sheet materials, allowing the telescopic cylinder 6 to support and adhere to the sheet material in the appropriate position, further improving the applicability of the equipment and the reliability of the processing.

[0041] Reference Figure 4 , Figure 5 The lower part of the positioning block 8 has multiple oblique holes 11, and a fixed rod 12 is slidably connected in the oblique hole 11. A sliding sleeve 13 is slidably sleeved on the guide rail 52, and the end of the fixed rod 12 is connected and fixed to the corresponding sliding sleeve 13.

[0042] Specifically, when the lifting frame 142 rises, it drives the positioning block 8 to rise synchronously. At this time, the fixing rod 12 and the inclined hole 11 cooperate with each other, forcing the positioning block 8 to move towards the center of the frame 1, thereby adjusting the orientation of the suspended sheet metal. In addition, by moving the sliding sleeve 13, the initial position of the positioning block 8 can be adjusted to ensure that when the telescopic cylinder 6 is in its minimum retracted state, the side of the positioning block 8 can just push the sheet metal, keeping it precisely in the center position.

[0043] On the one hand, by using the cooperation of the fixed rod 12 and the inclined hole 11, the vertical movement of the lifting frame 142 is converted into the horizontal adjustment force of the positioning block 8, realizing the automation of the plate orientation adjustment and reducing manual intervention; on the other hand, the position of the positioning block 8 can be flexibly adjusted by the sliding sleeve 13 to adapt to the centering requirements of different specifications of plates, improving the versatility of the equipment, while ensuring the accuracy of the plate centering and positioning, laying the foundation for the accuracy of subsequent laser cutting.

[0044] Reference Figure 6 The lifting frame 142 has two sliding sleeves 143 that are slidably connected to it. A drive ring 144 is fixedly connected between the two sliding sleeves 143. The drive ring 144 is slidably sleeved on the outer wall of the sealing cylinder 63. A U-shaped seat 145 is slidably sleeved on the lifting frame 142. The U-shaped seat 145 is located below the positioning block 8.

[0045] Specifically, the two electric push rods 141 extend and retract synchronously. When the lifting frame 142 rises, the two sliding sleeves 143 fitted on it will drive the drive ring 144 to rise together. After the drive ring 144 contacts the upper end of the sealing cylinder 63, it will drive the sealing cylinder 63 to move upward, thereby compressing the telescopic sleeve 62.

[0046] At the same time, the U-shaped seat 145 that is slidably connected on the lifting frame 142 will also rise together. When the top surface of the U-shaped seat 145 contacts the bottom surface of the positioning block 8, it will drive the positioning block 8 to move upward.

[0047] On the one hand, through the cooperation of the sliding sleeve 143, the drive ring 144 and the U-shaped seat 145, the lifting action of the lifting frame 142 can synchronously drive the compression of the telescopic sleeve 62 and the lifting of the positioning block 8, realizing the linkage of multiple components and ensuring the coordination of the plate suspension and positioning adjustment process; on the other hand, the components are connected by sliding sleeves, making the movement process smoother, reducing mechanical wear, and helping to improve the service life and working accuracy of the equipment.

[0048] It should be noted that, refer to Figure 7 Limiting hoops are fixed to the upper and lower ends of the outer wall of the fixed cylinder 61 and the upper end of the outer wall of the sealing cylinder 63. When the drive ring 144 rises to abut against the limiting hoop of the sealing cylinder 63, it first drives the telescopic cylinder 6 to rise as a whole. The top surface of the telescopic cylinder 6 drives the plate to rise away from the nail bed 2. Then, when the limiting ring 9 abuts against the lower limiting hoop of the fixed cylinder 61, the telescopic sleeve 62 begins to compress. The air inside the telescopic cylinder 6 is discharged through the upper port, so that an air film is formed between the upper port of the fixed cylinder 61 and the bottom surface of the plate. The plate is in a suspended state at this time.

[0049] Reference Figure 5 The top surface of the guide rail 52 is provided with a toothed groove 53. The top surface of the inner wall of the first sliding sleeve 10 and the top surface of the inner wall of the second sliding sleeve 13 are both fixed with positioning protrusions 15, which are engaged with the toothed groove 53.

[0050] Specifically, sliding sleeve 10 and sliding sleeve 2 13 can be moved and adjusted on the guide rail 52, allowing the telescopic cylinder 6 and positioning block 8 to be adapted and adjusted according to the size and cutting orientation of the sheet metal. Furthermore, the engagement between the positioning protrusion 15 and the toothed groove 53 stably restricts the telescopic cylinder 6 and positioning block 8 to specific positions on the guide rail 52, effectively preventing sliding deviations that may occur without manual adjustment.

[0051] Example 2, refer to Figure 3 , Figure 7 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: multiple elastic elements 7 are arranged in a ring with equal spacing. Each elastic element 7 includes a guide rod 71 that is fixedly connected to the lower part of the outer wall of the fixed cylinder 61. The lower end of the guide rod 71 movably passes through the upper part of the outer wall of the sealing cylinder 63. A compression spring 72 is sleeved on the outer wall of the guide rod 71. The two ends of the compression spring 72 are respectively connected to the fixed cylinder 61 and the sealing cylinder 63.

[0052] Specifically, when the lifting frame 142 rises and the telescopic cylinder 6 undergoes compression deformation, the compression spring 72 is compressed to store energy. When the lifting frame 142 stops rising, the sheet material descends and contacts the upper end of the telescopic cylinder 6. When the lifting frame 142 descends, the compression spring 72 returns to its original state, causing the telescopic sleeve 62 to extend. The space of the telescopic cylinder 6 increases while the internal air volume remains unchanged, thereby generating negative pressure and achieving stable adsorption of the sheet material.

[0053] Understandably, the sum of the elastic forces of all elastic elements 7 is greater than the weight of the sheet metal. When the telescopic cylinder 6 rises, the elastic force of the elastic elements 7 overcomes the weight of the sheet metal, thus driving the sheet metal to rise. When the limiting ring 9 abuts against the lower limiting hoop of the fixed cylinder 61, the compression spring 72 begins to compress and store force. The rest of the structure is the same as that of Embodiment 1.

[0054] Example 3, referring to Figure 8 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that a sealing ring 16 is fixedly installed on the inner wall of the sealing cylinder 63, and a through hole adapted to the sealing ring 16 is opened on the sealing cylinder 63. A sealing plate 17 is abutted and fitted inside the sealing ring 16, and a spring hinge is connected between the sealing plate 17 and the sealing ring 16.

[0055] Specifically, the sealing ring 16 and the sealing plate 17 cooperate with each other to form a one-way air intake mechanism from the outside to the inside on the sealing cylinder 63. When the telescopic cylinder 6 undergoes compression deformation, the sealing plate 17 will abut tightly against the sealing ring 16, so that the through hole on the sealing cylinder 63 is in a sealed state, effectively preventing air from leaking from the through hole.

[0056] Reference Figure 7 , Figure 8 A trapezoidal block 18 is fixedly connected to the side of the sealing plate 17 facing the through hole. One end of the inclined surface of the trapezoidal block 18 extends to the outside of the sealing cylinder 63. An L-shaped rod 19 is vertically slidably connected inside the trapezoidal block 18. The lower end of the L-shaped rod 19 abuts against the outer wall of the sealing cylinder 63. A rotating rod 20 is rotatably connected inside one end of the inclined surface of the trapezoidal block 18. One end of the rotating rod 20 slides in contact with the L-shaped rod 19.

[0057] Specifically, the lower end of the L-shaped rod 19 abuts against the outer wall of the sealing cylinder 63, restricting the rotation of the sealing plate 17 and preventing the sealing plate 17 from automatically opening due to excessive negative pressure inside the telescopic cylinder 6. When the telescopic cylinder 6 has attracted the sheet material and the sheet material has been placed on the nail bed 2, if the lifting frame 142 continues to descend, the drive ring 144 will contact the other end of the rotating rod 20 and drive the L-shaped rod 19 to rise. After the L-shaped rod 19 releases its contact with the outer wall of the sealing cylinder 63, the bottom surface of the drive ring 144 will contact the inclined surface of the trapezoidal block 18, thereby driving the sealing plate 17 to rotate, so that the sealing plate 17 no longer abuts against the sealing ring 16. At this time, the internal pressure of the telescopic cylinder 6 is balanced with the external pressure, thereby releasing the attraction of the sheet material. The remaining structure is the same as that of Embodiment 2.

[0058] Based on embodiments 1-3, the working principle of this invention is as follows: The sheet material to be processed is manually placed on the nail bed 2, with one end aligned with the inner wall of one side of the frame 1. The electric push rod 141 extends, driving the lifting frame 142 to rise. The drive ring 144 drives the sealing cylinder 63 to rise, causing the telescopic cylinder 6 to rise as a whole, lifting the sheet material away from the nail bed 2. Subsequently, the telescopic sleeve 62 is compressed, expelling internal air. An air film is formed between the upper end of the fixed cylinder 61 and the sheet material, suspending the sheet material. Simultaneously, the U-shaped seat 145 drives the positioning block 8 to rise. The fixed rod 12 cooperates with the inclined hole 11 to move the positioning block 8 towards the center, pushing the suspended sheet material to be centered. Subsequently, the electric push rod 141 retracts, causing the lifting frame 142 to descend. The compression spring 72 returns to its original position, causing the telescopic sleeve 62 to extend. A negative pressure is generated inside the telescopic cylinder 6. Through the one-way seal between the sealing ring 16 and the sealing plate 17, the sheet material is stably adsorbed on the nail bed 2. Subsequently, the laser cutter 3 processes the sheet material. After processing, the lifting frame 142 continues to descend, and the drive ring 144 drives the rotating rod 20 to rotate, causing the L-shaped rod 19 to rise. This, in turn, drives the sealing plate 17 connected to the trapezoidal block 18 to rotate, opening the sealing plate 17, releasing the negative pressure, and completing the processing cycle.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
