Technical Field

[0001] This invention relates to the field of laser cutting technology, specifically to a CNC laser cutting machine for processing composite material soundproof covers. Background Technology

[0002] CNC laser cutting machines are advanced thermal processing equipment that integrates laser technology and computer digital control. They use a high-energy-density laser beam as an invisible tool, which melts and vaporizes the material instantly by focusing it. The molten slag is blown away by auxiliary gas to complete the cutting. Composite material soundproof covers are noise reduction and protection structures made of multi-layer composite sound-absorbing and sound-insulating materials. They are usually composed of panels, damping layers, sound-absorbing cotton, and sealing components. They are lightweight, high-strength, corrosion-resistant, sound-insulating, heat-insulating, and flame-retardant. Their processing mainly involves CNC laser cutting, trimming, bending, bonding, and assembly, and can accurately form irregular components and installation holes.

[0022] As a further embodiment of the present invention, the fixing block is provided with a threaded hole, the timing belt is provided with a plurality of assembly holes at equal intervals, the through rod is slidably connected to the baffle, a spring is sleeved on the through rod, one end of the spring is fixedly connected to the lower part of the baffle, and the other end of the spring is fixedly connected to the upper part of the pressure hammer.

[0023] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses an adjusting motor to drive an adjusting screw to rotate. The adjusting screw drives a movable frame to move linearly along a slide groove via a threaded transmission. The movable frame simultaneously drives the upper movable platform to move synchronously along the connecting shaft, thereby adjusting the distance between the movable platform and the fixed platform to adapt to the processing requirements of different specifications of composite material soundproof cover raw materials. When the driving motor rotates the connecting shaft, the connecting shaft can simultaneously drive the main synchronous pulley and the auxiliary synchronous pulley to rotate synchronously, so that the main synchronous pulley and the auxiliary synchronous pulley drive the synchronous belt to rotate, thereby driving multiple fixed blocks to move. When the fixed block drives the movable plate to slide into the wedge-shaped opening on one side of the side plate, the inclined surface of the wedge-shaped opening can push the slider on one side of the movable plate, causing the movable plate to slide downward along the guide plate, so that the movable plate synchronously drives the pressure hammer to move downward. During the process, the pressure hammer can drive the through rod on the baffle. The slider slides upwards and simultaneously stretches the first spring. When the slider slides from the wedge-shaped opening into the limiting groove, the rubber pad under the pressure hammer will fit tightly against the surface of the composite material sound insulation cover material, thereby achieving elastic pressing and positioning of the material. This avoids excessive pressing force that could damage the material and effectively prevents the material from shifting during laser cutting, ensuring the flatness and processing accuracy of the cut. As the fixed block moves continuously, the slider can slide from the limiting groove into the wedge-shaped opening on the other side of the side plate. Then, the spring force of the first spring will rebound and pull the pressure hammer, allowing the movable plate to move upwards along the guide plate, thereby releasing the pressing state of the composite material sound insulation cover material for easy material removal. The continuous operation of the synchronous belt realizes the feeding and unloading cycle of the cutting process, eliminating the need for repeated manual adjustment of the clamping fixture and improving overall production efficiency. 2. In this invention, waste or finished products generated by laser cutting will fall from the fixed table and the movable table into the collection box. When the waste or finished products in the collection box accumulate to a certain amount, the auxiliary electric push rod is activated, which pulls the push plate to slide in the opening slot. During the process, the two ends of the hinge rod deflect on the connecting rod and the connecting pin respectively. Then, the deflected hinge rod pushes the hinge seat, causing the collection box to flip around the fixed rod through the connecting plate, making the collection box tilt. At this time, the waste or finished products in the collection box slide down the tilted collection box wall under its own gravity and fall smoothly into the discharge port on one side of the machine body, and finally discharge into the preset collection container, realizing the centralized collection and cleaning of waste and finished products. After the unloading is completed, the auxiliary electric push rod is controlled to push the push plate back, so that the push plate moves back along the opening slot, and the hinge rod deflects in the opposite direction, causing the collection box to gradually return to a horizontal state, waiting for the next material receiving and unloading operation. The whole process does not require manual intervention, reducing the intensity of manual labor. 3. This invention uses a working motor to drive a screw, causing the movable seat, which is threadedly engaged with the drive screw, to slide along a guide groove, thereby adjusting the working position of the laser cutting head. The main electric push rod then pushes the mounting plate downwards, bringing the laser cutting head closer to the raw material. During this process, the traction rod first slides within the inclined groove and pushes against the groove wall, causing the tilting frame to deflect around a fixed axis, turning it into a vertical position. At this point, the end of the laser cutting head is located between two connecting plates. The traction rod then slides from the inclined groove into the vertical groove and contacts the sliding block. The main electric push rod then continues to push the mounting plate downwards, adjusting the laser cutting head to the preset cutting height. During this process, the traction rod pushes the sliding block, causing the sliding block to move the vertical plate downwards along with the mounting plate. Finally, laser cutting is initiated. The head, in conjunction with the drive motor, moves the synchronous belt, allowing the raw material to move within the travel area of ​​the limiting groove. This enables automated cutting of the composite material soundproof cover raw material, meeting the processing requirements of different sizes and contours. The fixed motor rotates the connecting roller, causing the inclined annular guide groove to reciprocately push the protrusion, allowing the L-shaped plate to slide back and forth within the notch groove. During this process, the transverse groove on the L-shaped plate pushes the fixing pin, causing the fixing pin to slide along the skewed trajectory of the V-shaped groove. This allows the connecting plate to swing back and forth around the pin shaft on both sides of the laser cutting head end. At this time, an external air pump or exhaust fan can be connected to the connecting hose to allow the reciprocating connecting plate to draw out the harmful fumes generated through the smoke port below, preventing the spread of harmful fumes.

[0038] 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.

[0039] Please see Figures 1-12 The present invention provides a technical solution:

[0040] A CNC laser cutting machine for processing composite material soundproof covers includes a machine body 1. Anti-slip pads 48 are fixedly connected to the four corners of the machine body 1. The anti-slip pads 48 have anti-slip textures on their underside. The anti-slip pads 48 on the underside of the machine body 1 can increase the friction between the machine body 1 and the ground. The anti-slip textures on the underside of the anti-slip pads 48 form a tight fit with the ground, preventing the machine body 1 from shifting or shaking.

[0041] An opening groove 2 is formed on the wall of the machine body 1. A sliding groove 3 is formed below the opening groove 2 on the machine body 1. A movable frame 19 is slidably connected in the sliding groove 3. A movable platform 20 is fixedly connected above the movable frame 19. A fixed platform 8 is fixedly connected to the machine body 1. Fixed frames 11 are fixedly connected to both sides of the machine body 1. The fixed platform 8 and the movable platform 20 have the same length and shape, and the fixed platform 8 is positioned opposite to the fixed frame 11 and the movable platform 20. The fixed frame 11 and the fixed platform 8 are rotatably connected to the connecting shaft 12 on both sides via bearings. A drive motor 13 is fixedly installed on the fixed platform 8. The output shaft of the drive motor 13 is rotatably connected to the connecting shaft 12 on one side of the fixed platform 8. Connecting shaft 12, one end of which is sleeved with main connecting sleeve 14, and main synchronous pulley 15 is fixedly connected to main connecting sleeve 14. The other end of connecting shaft 12 is sleeved with auxiliary connecting sleeve 16, and auxiliary synchronous pulley 17 is fixedly connected to auxiliary connecting sleeve 16. Synchronous belts 18 are installed on both main synchronous pulleys 15 and both auxiliary synchronous pulleys 17. Protrusions 51 are fixedly connected to both sides of connecting shaft 12. Insertion holes 52 are opened on both main connecting sleeve 14 and auxiliary connecting sleeve 16. Connecting shaft 12 and protrusions 51 together form an insertion fit with insertion holes 52. Main connecting sleeve 14 and auxiliary connecting sleeve 16 are rotatably installed on fixed platform 8 and movable platform 20 respectively through bearings.

[0042] During operation, the drive motor 13 can rotate the connecting shaft 12 on one side of the fixed platform 8. The connecting shaft 12 can drive the main connecting sleeve 14 and the auxiliary connecting sleeve 16 to rotate synchronously through the precise engagement of the protrusion 51 and the insertion hole 52. This drives the main synchronous wheel 15 and the auxiliary synchronous wheel 17 to rotate together, thereby causing the two synchronous belts 18 installed on the main synchronous wheel 15 and the auxiliary synchronous wheel 17 to move synchronously. This achieves synchronous linkage between the fixed frame 11 and the connecting shafts 12 on both sides of the fixed platform 8.

[0043] An adjusting motor 4 is fixedly installed on one side of the slide 3. An adjusting screw 24 is connected to the output shaft of the adjusting motor 4. The adjusting screw 24 is rotatably connected to the slide 3 through a bearing. The adjusting screw 24 passes through the movable frame 19 and is threadedly installed with the movable frame 19. The movable frame 19 is fixedly connected to the two sides of the main telescopic cover 47. The main telescopic cover 47 is sleeved on the adjusting screw 24, and one end of the main telescopic cover 47 is fixedly connected to the wall of the slide 3.

[0044] During operation, the adjusting motor 4 is started to drive the adjusting screw 24 to rotate. Utilizing the threaded engagement between the adjusting screw 24 and the movable frame 19, the movable frame 19 can move along the slide groove 3 when the adjusting screw 24 rotates. During this process, the groove wall of the slide groove 3 can limit the movable frame 19, thereby preventing the movable frame 19 from tilting or twisting and ensuring that the movable table 20 maintains a horizontal state for linear displacement. During the movement of the movable frame 19, the movable frame 19 can simultaneously stretch or compress the two main telescopic covers 47 on both sides, allowing the two main telescopic covers 47 to flexibly expand and contract with the displacement of the movable frame 19, always completely covering the adjusting screw 24 inside. This effectively prevents composite material dust, debris, and slag generated during laser cutting from adhering to the threaded surface of the adjusting screw 24.

[0045] A guide groove 5 is provided on the body 1. A working motor 6 is fixedly installed on one side of the body 1 in the guide groove 5. The output shaft of the working motor 6 is connected to a drive screw 49. The drive screw 49 is rotatably connected in the guide groove 5 through a bearing. A movable seat 25 is slidably connected in the guide groove 5. The drive screw 49 passes through the movable seat 25 and is threadedly installed in the movable seat 25. A secondary telescopic cover 50 is fixedly connected to both sides of the movable seat 25. The secondary telescopic cover 50 is sleeved on the drive screw 49, and one end of the secondary telescopic cover 50 is connected to the guide groove. 5. The groove wall is fixedly connected. Two limiting strips 26 are fixedly connected to one side below the movable seat 25. A main electric push rod 27 is fixedly installed on the limiting strip 26. A mounting plate 28 is fixedly connected to the movable end of the main electric push rod 27. A connecting strip 29 is fixedly connected above the mounting plate 28. A laser cutting head 30 is fixedly installed on the mounting plate 28. The connecting strip 29 slides between the two limiting strips 26. Grooves 53 are opened on both sides of the connecting strip 29. The limiting strips 26 are set in the grooves 53 and contact the groove wall of the groove 53.

[0046] During operation, the drive screw 49 is rotated by the working motor 6, causing the movable seat 25, which is threadedly engaged with the drive screw 49, to move along the guide groove 5. During this process, the groove wall of the guide groove 5 can limit and guide the movable seat 25, ensuring its smooth and directional movement and preventing deviation during movement. The secondary telescopic cover 50 can cover and protect the drive screw 49 in real time to prevent the adhesion of dust and impurities. When the movable seat 25 moves to the working position, the main electric push rod 27 is activated to push the mounting plate 28 down, causing the mounting plate 28 to drive the connecting strip 29 to slide between the two limiting strips 26. The grooves 53 on both sides of the connecting strip 29 are precisely fitted with the limiting strips 26, so that the limiting strips 26 form a bidirectional limit on the connecting strip 29, effectively preventing tilting or deviation during the downward movement of the mounting plate 28, ensuring that the laser cutting head 30 can be vertically aligned with the blank cutting position, and ensuring the verticality and accuracy of the cutting.

[0047] A fixed rod 9 is fixedly connected to the machine body 1. A collection box 10 is rotatably installed on the machine body 1 via the fixed rod 9. A discharge port 7 is opened on one side of the machine body 1 corresponding to the position of the collection box 10. A connecting plate 31 is fixedly connected to both sides of the collection box 10. A hinge seat 32 is fixedly connected to the bottom of the collection box 10. A connecting pin 33 is fixedly connected to both sides of the hinge seat 32. An auxiliary electric push rod 34 is fixedly installed in the opening slot 2. A push plate 35 is fixedly connected to the movable end of the auxiliary electric push rod 34. A connecting rod 36 is fixedly connected to the push plate 35. A hinge rod 37 is rotatably connected to the push plate 35 via the connecting rod 36. A ramp 38 is provided above the push plate 35. The connecting plate 31 is rotatably connected to the fixed rod 9. The hinge seat 32 and the push plate 35 are both set in the opening slot 2. The push plate 35 slides in the opening slot 2 and contacts the slot wall of the opening slot 2. One end of the hinge rod 37 is rotatably connected to the connecting pin 33.

[0048] During operation, the auxiliary electric push rod 34 can pull the push plate 35 to slide within the opening slot 2. The contact between the opening slot 2 wall and the push plate 35 allows the opening slot 2 to limit the push plate 35, preventing it from shifting during movement. During the movement of the push plate 35, the hinge rod 37 can deflect on the connecting rod 36 and the connecting pin 33, thereby causing the push plate 35 to push the collection box 10 through the hinge rod 37. This causes the collection box 10 to tilt and rotate around the fixed rod 9 towards the discharge port 7, thus allowing the material collected in the collection box 10 to be poured out from the discharge port 7. When the push plate 35 is pushed back to reset the collection box 10, the hinge rod 37 can come into contact with the slope surface of the ramp 38, thereby using the ramp 38 to restrict the hinge rod 37 and prevent excessive deflection from causing jamming.

[0049] Both the movable platform 20 and the fixed platform 8 are fixedly connected to side plates 21. Limiting grooves 22 are provided on the side plates 21, and wedge-shaped openings 23 are provided on both sides of the side plates 21. The limiting grooves 22 are horizontally designed, and both ends of the limiting grooves 22 are connected to the wedge-shaped openings 23. Multiple fixing blocks 39 are fixedly installed on the synchronous belt 18 by bolts. A guide plate 40 is fixedly connected above the fixing blocks 39, and a baffle 41 is fixedly connected above the guide plate 40. A movable plate 42 is slidably connected through the guide plate 40, and a slider 43 is fixedly connected to one side of the movable plate 42. 43 slides within the limiting groove 22 and the wedge-shaped opening 23. A pressure hammer 44 is fixedly connected to the other side of the movable plate 42. A rubber pad 45 is fixedly connected below the pressure hammer 44. A through rod 46 is fixedly connected above the pressure hammer 44. A threaded hole 54 is opened on the fixed block 39. Multiple assembly holes 55 are opened at equal intervals on the synchronous belt 18. The through rod 46 passes through the baffle 41 and is slidably connected to the baffle 41. A spring 56 is sleeved on the through rod 46. One end of the spring 56 is fixedly connected to the lower part of the baffle 41, and the other end of the spring 56 is fixedly connected to the upper part of the pressure hammer 44.

[0050] During operation, the synchronous belt 18 drives multiple fixed blocks 39 to move. When the slider 43 slides into the wedge-shaped opening 23, the inclined surface of the wedge-shaped opening 23 can push the slider 43, causing the movable plate 42 to drive the pressure hammer 44 to move downward. At this time, the through rod 46 slides down synchronously along the baffle 41. During the downward movement of the pressure hammer 44, the rubber pad 45 will first contact the raw material placed above the fixed block 39. As the slider 43 continues to slide along the inclined surface of the wedge-shaped opening 23, the pushing force gradually increases until the slider 43 slides into the limiting groove 22. At this time, the pressure hammer 44 reaches the maximum downward stroke, and the rubber pad 45 tightly adheres to the surface of the raw material, completing the pressing and positioning operation of the raw material. This prevents the workpiece from shifting or shaking during subsequent processing. The operation is simple and convenient, and no manual adjustment is required.

[0051] A fixed shaft 57 is rotatably connected to the side of the movable seat 25 away from the limiting strip 26. A swing arm 58 is fixedly connected to the fixed shaft 57. Inclined grooves 59 and vertical grooves 60 are opened on the two side walls of the swing arm 58. The inclined grooves 59 and vertical grooves 60 are interconnected.

[0054] Working principle of this invention:

[0055] First, by starting the adjusting motor 4, the adjusting motor 4 drives the adjusting screw 24 to rotate. As the adjusting screw 24 rotates, the movable frame 19, which is threadedly engaged with the adjusting screw 24, can move linearly along the slide groove 3. The movable frame 19 can simultaneously drive the upper movable platform 20 to move along the connecting shaft 12, thereby flexibly adjusting the distance between the movable platform 20 and the fixed platform 8 to adapt to the size and specifications of the composite material soundproof cover raw material to be processed.

[0056] Then, the drive motor 13 is started, which drives the connecting shaft 12 on one side of the fixed platform 8 to rotate. The connecting shaft 12 can drive the main synchronous wheel 15 and the auxiliary synchronous wheel 17 to rotate in tandem through the protrusion 51. Then, the main synchronous wheel 15 and the auxiliary synchronous wheel 17 drive the two synchronous belts 18 to rotate, causing multiple fixed blocks 39 to move together with the synchronous belts 18. When the fixed block 39 drives the movable plate 42 to slide into the wedge-shaped opening 23 on one side of the side plate 21, the inclined surface of the wedge-shaped opening 23 can push the slider 43 on one side of the movable plate 42, causing the movable plate 42 to slide down along the guide plate 40, thereby causing the pressure hammer 44 to move down synchronously.

[0057] During this process, the hammer 44 drives the through rod 46 to slide through the baffle 41, and at the same time stretches the spring 56. When the slider 43 slides from the wedge-shaped opening 23 into the limiting groove 22, the rubber pad 45 under the hammer 44 is in close contact with the surface of the raw material placed above the fixed block 39, and the limiting groove 22 can limit the movable plate 42 to prevent the movable plate 42 and the hammer 44 from moving upwards accidentally, thereby achieving elastic pressing and positioning of the raw material.

[0058] After the raw material is pressed and positioned, the working motor 6 is started to rotate the drive screw 49, so that the movable seat 25, which is threaded with the drive screw 49, slides along the guide groove 5, thereby adjusting the working position of the laser cutting head 30. Meanwhile, the main electric push rod 27 can push the mounting plate 28 down, causing the laser cutting head 30 to approach the raw material. During the process, the traction rod 79 first slides in the inclined groove 59 and pushes the groove wall of the inclined groove 59, causing the deflector frame 58 to deflect around the fixed axis 57, so that the deflector frame 58 turns to a vertical state. At this time, the end of the laser cutting head 30 is located between the two connecting plates 64, while the traction rod 79 slides from the inclined groove 59 into the vertical groove 60 and contacts the sliding block 62.

[0059] Then, the main electric push rod 27 continues to push the mounting plate 28 down, causing the laser cutting head 30 to adjust to the preset cutting height. During this process, the traction rod 79 can push the sliding block 62, causing the sliding block 62 to move along the vertical groove 60 and the vertical plate 61 down with the mounting plate 28. Then, the laser cutting head 30 is started, and the drive motor 13 drives the synchronous belt 18 to move, so that the raw material can move within the stroke area of ​​the limit groove 22, thereby realizing the automated cutting of the composite material sound insulation cover raw material and meeting the processing requirements of different sizes and different contour shapes.

[0060] The fixed motor 68 can rotate the connecting roller 67, causing the inclined annular guide groove 73 to push the protrusion 76 back and forth, so that the L-shaped plate 74 can slide back and forth in the notch groove 66. During the process, the transverse groove 75 on the L-shaped plate 74 can push the fixing pin 72, causing the fixing pin 72 to slide along the skewed trajectory of the V-shaped groove 65, thereby allowing the connecting plate 64 to swing back and forth around the pin shaft 71 on both sides of the end of the laser cutting head 30. At this time, an external air pump or exhaust fan can be used on the connecting hose 70 to allow the reciprocating connecting plate 64 to perform range-wide suction of the generated harmful smoke and dust through the smoke port 69 below.

[0061] Waste materials generated during the cutting process or finished products will fall from the gap between the fixed table 8 and the movable table 20 into the collection box 10 below, thus achieving the initial collection of waste materials or finished products. When the waste materials or finished products in the collection box 10 accumulate to the preset amount, the auxiliary electric push rod 34 is activated, causing the auxiliary electric push rod 34 to pull the push plate 35 to slide in the opening slot 2. During the process, the two ends of the hinge rod 37 can deflect on the connecting rod 36 and the connecting pin 33 respectively, thereby causing the push plate 35 to push the hinge seat 32 through the deflected hinge rod 37, causing the collection box 10 to rotate around the fixed rod 9 through the connecting plate 31, making the collection box 10 tilt as a whole. At this time, the waste materials and finished products in the collection box 10 slide down the tilted collection box 10 wall under their own gravity and fall smoothly into the discharge port 7 on one side of the machine body 1, and finally discharge into the preset collection container, thus achieving the centralized collection and cleaning of waste materials and finished products.

[0062] After unloading is completed, the auxiliary electric push rod 34 pushes the push plate 35 back, causing the push plate 35 to move back along the opening slot 2. Then, the collection box 10 is pulled back through the hinge rod 37, causing the collection box 10 to gradually return to a horizontal state, waiting for the next material receiving and unloading operation. As the synchronous belt 18 continues to drive the laser-cut material to move to one side, the slider 43 can gradually slide from the limiting slot 22 into the wedge-shaped opening 23 on the other side of the side plate 21. Then, the spring force of the spring 56 pulls the pressure hammer 44 back, so that the movable plate 42 can move upward along the guide plate 40, thereby releasing the pressing state on the material to facilitate unloading.
