Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, and in particular to a laser cutting machine with adaptive anti-vibration clamping. Background Technology

[0002] Laser cutting machines, as high-precision processing equipment, are widely used in metal processing, automobile manufacturing, aerospace and other fields. Because laser cutting requires high-precision positioning and a stable cutting environment, the clamping of the material being cut is one of the key aspects to ensure cutting quality; therefore, effective clamping of the material is essential.

[0003] However, the clamping function of existing laser cutting machines requires high clamping force when the clamping point is far from the cutting position. Furthermore, after localized laser cutting of the material, stress is generated at the cutting location. A distance from the clamping point makes it difficult to suppress this stress, leading to vibration and poor clamping effectiveness and stability. This results in material displacement or deformation during cutting, affecting cutting accuracy and quality. While setting the clamping point closer to the cutting position can improve clamping effectiveness to some extent, dust and debris generated during cutting tend to adhere to the clamping device. Over time, these deposits accumulate, reducing the clamping force and flexibility of the device, leading to a gradual deterioration in subsequent clamping performance and affecting the continuity and stability of the cutting process.

[0004] To address this, an adaptive anti-vibration clamping laser cutting machine is proposed. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention provides an adaptive anti-vibration clamping laser cutting machine.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an adaptive anti-vibration clamping laser cutting machine, comprising left and right frames and front and rear frames. The table surface of the front and rear frames is provided with a cutting platform composed of several support bars. A cutting work platform is provided on the left and right frames, and the cutting work platform is equipped with a laser cutting head for generating laser light to achieve cutting. Waste cylinders for collecting cutting debris are connected to the left and right frames below the cutting platform. Lifting devices are installed on the outer sides of the front and rear frames. The drive shaft of the lifting devices is connected to a clamping frame, and several [unclear - possibly referring to a specific type of clamping device] are arranged on the clamping frame. The clamping assembly includes two clamping heads that are in a corresponding and fitted state. Each clamping head has an air extraction port on its corresponding surface. A negative pressure air extraction assembly is provided on the rear frame. The negative pressure air extraction assembly is connected to the clamping head and communicates with the air extraction port through an air pipe. The clamping frame is provided with a displacement assembly for adjusting the position of the clamping assembly. The inner side of the clamping frame is also provided with a deformation assembly for driving the corresponding two clamping heads to rotate and unfold. An annular groove is opened in the center of the clamping head. A toothed roller is connected to the annular groove through a rotating bearing. A toothed transmission belt is fitted on the toothed roller.

[0007] As a preferred embodiment of the present invention, the displacement assembly includes a displacement frame, a plurality of clamping components are arranged on the front side of the displacement frame, a displacement motor is installed at one end of the displacement frame, the transmission shaft of the displacement motor is connected to a drive gear, an elongated hole is opened on one side of the clamping frame, a guide rack is connected to the bottom wall of the elongated hole, the drive gear meshes with the guide rack, a linear guide rail is connected to the side of the clamping frame away from the guide rack, a slide block is slidably installed on the linear guide rail, and one end of the displacement frame is connected to the slide block.

[0008] As a preferred embodiment of the present invention, the deformation assembly includes a sleeve connected to the front side of the displacement frame. The number of sleeves is several, consistent with the number of clamping assemblies. Several clamping assemblies are respectively arranged on the front side of several sleeves. Two sliding holes are formed on the top surface of the sleeve, and a guide rod is connected inside each sliding hole. A slider is slidably connected to the guide rod, and a rotating shaft is rotatably connected to the bottom end of the slider. A connecting pin is connected to the rotating shaft, and the outer end of the connecting pin is connected to a clamping head. A rotating gear is connected to the bottom end of the rotating shaft. A deformation rack is fitted inside the sleeve, and teeth are provided on both sides of the deformation rack, meshing with two rotating gears at corresponding positions. A control motor is installed on the rear side of the displacement frame corresponding to the positions of the sleeves. The drive shaft of the control motor passes through the displacement frame and is connected to the deformation rack at the corresponding position. The front side and bottom of the sleeve are open, and the inner wall of the top surface of the sleeve is higher than the clamping head. A limit frame is connected above each of the sleeves on the displacement frame, and a locking motor is installed on the limit frame. A limit pin is connected to the drive shaft of the locking motor, and a key is connected to the top surface of the two sliders at corresponding positions.

[0009] As a preferred embodiment of the present invention, a connecting frame is connected to the rear end of the clamping head, and a sleeve hole is opened on the rear side of the connecting frame. The end of the connecting pin is sleeved in the sleeve hole, and the end of the connecting pin is connected to a limiting plate that abuts against the front and rear openings of the sleeve hole, so that the connecting pin is connected to the clamping head. The rear end of the connecting frame is curved, and the central axis of the curved surface corresponds to the axis of the rotation shaft.

[0010] As a preferred embodiment of the present invention, the negative pressure exhaust assembly includes a negative pressure fan, which is installed on the left and right frames. A filter box is also connected to the left and right frames. A filter plate filled with filter media is inserted into the filter box. The air inlet of the negative pressure fan is connected to and communicates with the bottom side of the filter box through an exhaust pipe. An exhaust pipe is connected to and communicates with the top side of the filter box. A central cylinder is connected to the rear side of the displacement frame. Several air pipes are connected to and communicate with the exhaust pipe. The free end of the exhaust pipe is connected to and communicates with the exhaust pipe.

[0011] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0012] 1. The displacement component drives the clamping head to clamp the material in the area close to the cutting position, and the deformation component drives the clamping head to automatically avoid the cutting position, so that the clamping points are close to and distributed near the cutting area, thereby improving the clamping effect, reducing the clamping force required, and avoiding problems such as material position displacement caused by stress vibration after material cutting.

[0013] 2. The negative pressure suction assembly, through the unfolded clamping head, is used to extract air and remove dust from the cutting position. This not only aligns the suction position with the cutting position but also concentrates the suction effect on the cutting position, improving the efficiency and effectiveness of removing dust and debris generated during cutting. It also prevents dust and debris from adhering to the clamping fixture, thus avoiding affecting the clamping effect and stability.

[0014] 3. With the characteristic of movable clamping heads that can change the clamping position, the material is automatically clamped after being placed on the cutting table. It can automatically adapt to materials of different sizes, thicknesses and shapes, thereby improving the clamping efficiency and effect.

[0015] 4. By adding several components to the front of the clamping frame, and utilizing the interlocking end positions of several clamping heads, the clamping heads can be arranged in a staggered or arc-shaped manner. When cutting materials such as arc-shaped tubes and irregularly shaped tubes, the clamping heads can clamp the material from both the front and back sides in a manner that adapts to the shape of the material. This allows the clamping assembly to clamp not only plate-shaped materials but also tubular materials of different shapes, thereby improving the adaptability of the clamping function to different materials. Furthermore, the dust removal function of the clamping head is not affected, and the clamping point is kept close to the cutting area for clamping without being affected by dust and debris adhesion.

[0016] 5. The negative pressure suction component on the clamping head allows the clamping head to fit together more tightly when closed, making it more difficult to separate when the clamping head is subjected to external force, thus maintaining the stability of the state.

[0017] 6. By setting the connecting frame, when the clamping head is unfolded or closed, the connecting pin will first lift the clamping head and detach it from the material through the sleeve hole, avoiding the deformation of the clamping head from applying a pushing force to the material, thereby ensuring the stability of material clamping.

[0018] 7. By using a transmission belt, when the displacement component drives the clamping head to change position, the transmission belt runs above the material. Under the condition of maintaining applied pressure, it avoids the friction force from pushing the material to move. In the closed state, the clamping head limits the lateral movement of the material through the transmission belt, while in the unfolded state, the clamping head limits the longitudinal movement of the material through the transmission belt, thereby ensuring the stability of the material's planar position.

[0026] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0027] Example: Figure 1-6As shown, an adaptive anti-vibration clamping laser cutting machine includes left and right frames 10 and front and rear frames 11. There are two sets of both left and right frames 10 and front and rear frames 11. The two sets of left and right frames 10 are distributed left and right, and the two sets of front and rear frames 11 are located at the front and rear ends of corresponding surfaces of the two sets of left and right frames 10. A cutting platform 12 composed of several support bars is provided on the table surface of the front and rear frames 11. A cutting work platform 13 is provided on the left and right frames 10. The cutting work platform 13 is a gantry moving platform. The cutting work platform 13 includes a gantry, a first traveling track that can drive the gantry to move back and forth, a second traveling track that moves left and right on the gantry, and a lifting track on the second traveling track. These are existing technologies and will not be described in detail here. A laser cutting head 14 for generating laser light to achieve cutting is provided on the lifting track of the cutting work platform 13. The laser cutting head 14 is also existing technology and generates laser light. The device consists of a projector, a cutting head, and a beam transmission assembly, which will not be described in detail here. A control cabinet is also provided on one side of the left and right frames 10. Controllers, cable carriers, and other components can also be installed on the device according to existing technology. Lifting devices 15 are installed on the outer sides of the front and rear frames 11. The lifting devices 15 use cylinders, and the drive shaft of the lifting devices 15 is connected to a clamping frame 16. Several clamping components are arranged on the clamping frame 16. Each clamping component includes two clamping heads 17, which are in a corresponding and fitted state. Air extraction ports 18 are provided on the corresponding surfaces of the two clamping heads 17. Negative pressure air extraction components are provided on the rear front and rear frames 11. The negative pressure air extraction components are connected to the clamping heads 17 through air pipes 19 and communicate with the air extraction ports 18. The clamping frame 16 is provided with a displacement component for adjusting the position of the clamping components. A deformation component for driving the corresponding two clamping heads 17 to rotate and unfold is also provided on the inner side of the clamping frame 16.

[0028] Specifically, the material to be cut is placed on the cutting table 12. The lifting device 15 is activated, driving the clamping frame 16 to descend, allowing the clamping head 17 to apply pressure to the material for clamping. After debugging and measurement, the cutting platform 13 drives the laser cutting head 14 to move back and forth, left and right, and up and down, so that the laser cutting head 14 in the activated state can cut the material into the required shape. During the horizontal cutting process, the deformation component drives the clamping head 17 at the corresponding cutting position to unfold from one side, while the clamping heads 17 at other positions remain in the clamping position, freeing up the cutting position. At the same time, the unfolded air extraction port 18 sucks away the dust and debris generated during the cutting process through the activation of the negative pressure air extraction component. Then, as the cutting position changes, the deformation component drives the clamping head 17 at the corresponding position to unfold, while the clamping head 17 at the non-corresponding position returns to its original position. When the laser cutting head 14 changes its longitudinal position, the displacement component drives the clamping head 17 to change its longitudinal position.

[0029] like Figure 2 and Figure 3As shown, the displacement assembly includes a displacement frame 20, which is C-shaped. Several clamping components are arranged on the front side of the displacement frame 20. A displacement motor 21 is installed at one end of the displacement frame 20. The displacement motor 21 is a motor with a self-locking function. The drive shaft of the displacement motor 21 is connected to a drive gear 22. A long hole is opened on one side of the clamping frame 16. A guide rack 23 is connected to the bottom wall of the long hole. The drive gear 22 meshes with the guide rack 23. A linear guide rail 24 is connected to the side of the clamping frame 16 away from the guide rack 23. A slide block 25 is slidably installed on the linear guide rail 24. One end of the displacement frame 20 is connected to the slide block 25.

[0030] Specifically, the displacement motor 21 starts and drives the drive gear 22 to rotate. Depending on whether it rotates forward or backward, the drive gear 22 and the guide rack 23 mesh to generate a thrust on the displacement frame 20, allowing the displacement frame 20 to move back and forth on the clamping frame 16, thereby changing the front and back position of the clamping head 17.

[0031] like Figure 2 and Figure 4 As shown, the deformation assembly includes a sleeve 26, which is connected to the front side of the displacement frame 20. There are several sleeves 26, consistent with the clamping assembly. Several clamping assemblies are respectively arranged on the front side of several sleeves 26. The front side of the sleeve 26 is a rectangular frame. Two sliding holes 27 are provided on the top surface of the sleeve 26, distributed left and right. A guide rod 28 is connected inside the sliding hole 27. A slider 29 is slidably connected to the guide rod 28. The bottom end of the slider 29 is connected to a rotating shaft 30 via a rotating bearing. A T-shaped connecting pin 31 is connected to the rotating shaft 30. The outer end of the connecting pin 31... Connected to the clamping head 17, the bottom end of the rotating shaft 30 is connected to a rotating gear 32. A deformable rack 33 is fitted inside the sleeve 26. The deformable rack 33 has teeth on both sides and meshes with two rotating gears 32 at corresponding positions. A control motor 34 is installed on the rear side of the displacement frame 20 at the positions of several sleeves 26. The control motor 34 is a telescopic motor. The drive shaft of the control motor 34 passes through the displacement frame 20 and is connected to the deformable rack 33 at the corresponding positions. The front side and bottom of the sleeve 26 are open, and the inner wall of the top surface of the sleeve 26 is higher than the clamping head 17.

[0032] Specifically, the control motor 34 controls the forward and backward movement of the deformable rack 33. When the deformable rack 33 moves forward, it drives the rotating gear 32 to rotate, causing the two clamping heads 17 connected by the connecting pin 31 to unfold outward. When the deformable rack 33 moves backward, it causes the unfolded clamping heads 17 to close, thus controlling the unfolding and closing of the clamping heads 17. When the negative pressure suction assembly is activated, in order to ensure the strength of the suction and dust removal, the power of the negative pressure suction assembly is much greater than the airflow of the suction port 18 in the unfolded state. This causes the two clamping heads 17 to fit together more tightly due to the negative pressure. Therefore, when the deformable rack 33 moves forward and backward, the rotation of the rotating gear 32 is resisted, and the deformable rack 33 will drive the rotating gear 32 to slide in the sliding hole 27, thereby causing the clamping heads 17 to slide back and forth on the sleeve 26, changing several sets of The position of the clamping head 17 is determined, and then the motor 34 is controlled to stop locking the position of the deformable rack 33, so that the position of the clamping head 17 is fixed. This allows the clamping heads 17 to be arranged in an alternating or arc-shaped manner. Therefore, when cutting materials such as arc-shaped tubes and irregular-shaped tubes, after adding a displacement component, clamping component, deformation component, and negative pressure suction component (not shown in the figure) to the front side of the clamping frame 16, the position of the clamping head 17 is changed to adapt to the shape of the material. Then, the material is clamped from both the front and rear sides, which can stably clamp the material. The function of the clamping head 17 in unfolding and suction dust removal is the same as when cutting ordinary materials. When the deformable rack 33 drives the rotating gear 32 to move to the end of the sliding hole 27, the rotating gear 32 can no longer move. Allowing the deformable rack 33 to continue sliding can apply a rotational thrust greater than the negative pressure, thereby driving the clamping head 17 to perform the unfolding or closing function.

[0033] like Figure 2 As shown, the displacement frame 20 is connected to a limit frame 35 above several sleeves 26. A locking motor 36 is installed on the limit frame 35. The locking motor 36 is a telescopic motor. The drive shaft of the locking motor 36 is connected to a limit pin 37. The limit pin 37 is C-shaped and its concave side corresponds to the rear end wall of the sliding hole 27. The top surfaces of the two sliders 29 at the corresponding positions are connected to a fitting key 38. The fitting key 38 is adapted to the concave surface of the limit pin 37.

[0034] Specifically, when the deformable rack 33 pulls the slider 29 to the rear end wall of the sliding hole 27, the engaging motor 36 controls the limit pin 37 to descend and engage with the locking key 38, thereby limiting the position of the slider 29. Then, when the deformable rack 33 moves back and forth, it will drive the clamping head 17 to unfold or close, thereby limiting the deformation position of the clamping head 17 to the rear side of the sleeve 26, preventing the clamping head 17 from touching the material when unfolding or closing.

[0035] like Figure 5As shown, the clamping head 17 has an annular groove in the center, and a toothed roller 39 is connected to the annular groove through a rotating bearing. A toothed transmission belt 40 is fitted onto the toothed roller 39. The transmission belt 40 is made of a high-temperature resistant material.

[0036] Specifically, when the clamping head 17 moves back and forth, the transmission belt 40 abuts against the material and rotates, thereby reducing the friction between the clamping head 17 and the material and avoiding problems such as wear of the clamping head 17 or displacement of the material.

[0037] like Figure 5 As shown, the rear end of the clamping head 17 is connected to a connecting frame 41. The rear side of the connecting frame 41 has a V-shaped sleeve hole 42. The end of the connecting pin 31 is fitted into the sleeve hole 42, and the end of the connecting pin 31 is connected to a limiting plate 43 that abuts against the front and rear openings of the sleeve hole 42, so that the connecting pin 31 is connected to the clamping head 17. The rear end of the connecting frame 41 is curved, and the central axis of the curved surface corresponds to the axis of the rotating shaft 30.

[0038] Specifically, when the deformable rack 33 drives the rotating gear 32 to rotate, because the clamping head 17 is in contact with the material, there is a certain resistance between them. The connecting pin 31 will first slide in the sleeve hole 42 and lift the clamping head 17 along the wall of the sleeve hole 42. Then, after the clamping head 17 is no longer in close contact with the material, the connecting pin 31 pushes the clamping head 17 to close or open along the inclined surface of the sleeve hole 42. After the clamping head 17 closes or opens to the limit, the connecting pin 31 slides in the sleeve hole 42 again and pushes the clamping head along the inclined surface. The 17 descends, causing the clamping head 17 to press tightly against the material, restricting the longitudinal movement of the material. The clamping head 17 in the closed state restricts the lateral movement of the material. It should be noted that during the unfolding process of the clamping head 17, the power of the negative pressure suction component is appropriately reduced to facilitate the unfolding of the clamping head 17. In addition, after the clamping head 17 in the avoidance position completes the unfolding action, the clamping head 17 that needs to be reset will perform the closing action. When the displacement component is driven, all clamping heads 17 are reset to the closed state.

[0039] like Figure 6 As shown, the negative pressure exhaust assembly includes a negative pressure fan 44, which is mounted on the left and right frames 10. A filter box 45 is also connected to the left and right frames 10. A filter plate 46 filled with filter media is inserted inside the filter box 45. The air inlet of the negative pressure fan 44 is connected to the bottom side of the filter box 45 through an exhaust pipe 47. An exhaust pipe 48 is connected to the top side of the filter box 45. A central cylinder 49 is connected to the rear side of the displacement frame 20. Several air pipes 19 are connected to the exhaust pipe 48. The free end of the exhaust pipe 48 is connected to the exhaust pipe 48.

[0040] Specifically, after the negative pressure fan 44 is started, it applies the suction function to the central cylinder 49 through the paths of suction pipe 1 47 and suction pipe 2 48, and then distributes it to several air pipes 19 through the central cylinder 49, so that the suction port 18 generates a negative pressure suction function. The airflow drawn into the negative pressure fan 44 is filtered by the filter plate 46 to avoid polluting the external environment and to ensure the service life of the negative pressure fan 44.

[0041] like Figure 1 As shown, the left and right frames 10 are connected to a waste cylinder 50 for collecting cutting debris below the cutting table 12.

[0042] It should be noted that the structural motion control in this application is achieved by setting up sensors, which is a well-known existing technology and will not be described in detail here.

[0043] Working principle:

[0044] Before use: Place the material to be cut on the cutting platform 12. Start the lifting device 15 to drive the clamping frame 16 to descend and apply pressure to the material to achieve clamping. After debugging, measurement and other steps, the cutting work platform 13 drives the laser cutting head 14 to move back and forth, left and right and up and down, so that the laser cutting head 14 in the start state can cut the material into the required shape.

[0045] In use: First, the control motor 34 at the corresponding cutting position controls the deformable rack 33 to move backward, pulling the clamping head 17 backward. After reaching the limit, the deformable component controls the clamping head 17 to unfold behind the cutting position. Then, the negative pressure suction component is activated to absorb the dust, debris and other waste generated during cutting. The waste in the airflow is filtered through the filter box 45 and then discharged.

[0046] In the second step, the laser cutting head 14 first moves laterally to change the cutting position. The clamping head 17, which is located at the subsequent cutting position, unfolds in advance to avoid the cutting position. Then, after the laser cutting head 14 reaches the subsequent cutting position, the deformation component drives the clamping head 17, which has disengaged from the cutting position, to close up at the rear and then move forward to the clamping point.

[0047] Third, after completing the horizontal row of cuts, turn off the negative pressure suction component, the deformation component will close and reset the unfolded clamping head 17, and then the displacement component will move the clamping head 17 to the next row as a whole, and then repeat the first and second steps.

[0048] Fourth step: When cutting materials such as profiles, curved tubes, and irregular tubes, a clamping component, a displacement component, a deformation component, and a negative pressure suction component are installed on the front side of the clamping frame 16. After the clamping head 17 near the cutting position is unfolded in advance, the deforming rack 33 pushes the closed clamping head 17 to move, changing the position of the clamping head 17 to adapt to the shape of the material, and then clamps the material from both the front and rear sides to stably clamp the material.

[0049] After use: Reset the unfolded clamping head 17, and the lifting device 15 pushes the clamping frame 16 to lift it to detach from the material, making it easier to pick up the material.

[0050] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
