Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, in particular to a self-adaptive shock-proof clamping laser cutting machine. Background Art

[0002] As a high-precision processing equipment, laser cutting machines are widely used in metal processing, automobile manufacturing, aerospace and other fields. Since laser cutting requires high-precision positioning and a stable cutting environment, clamping the cutting material is one of the key links to ensure cutting quality, so it is very necessary to effectively clamp the cutting material.

[0003] However, when the clamping function of the existing laser cutting machine is in use, when the clamping point is far away from the cutting position, the clamping force requirement will be very high, and after the material is partially laser cut, stress will be generated at the cutting position. If the clamping point is far away, it is difficult to suppress the stress, and vibration problems are likely to occur, resulting in poor clamping effect and stability, causing the material to easily move or deform during the cutting process, thereby affecting the cutting accuracy and quality. However, if the clamping point is set close to the cutting position, although the clamping effect can be improved to a certain extent, the dust and debris generated during the cutting process are easy to adhere to the clamping device. Over time, these adhesions will gradually accumulate, reducing the clamping force and flexibility of the clamping device, causing the subsequent clamping effect to gradually deteriorate, affecting the continuity and stability of the cutting work.

[0004] For this purpose, a laser cutting machine with adaptive shock-proof clamping is proposed. Summary of the invention

An annular groove is provided in the center of the clamping head. A gear roller is connected to the annular groove through a rotating bearing, and a toothed transmission belt is inserted into the gear roller.

[0007] As a preferred technical solution of the present invention, the displacement assembly includes a displacement frame, a plurality of clamping assemblies are arranged on the front side of the displacement frame, a displacement motor is installed at one end of the displacement frame, a transmission shaft of the displacement motor is connected to a driving gear, a long hole is opened on one side of the clamping frame, a guide rack is connected to the bottom wall of the long hole, the driving gear is meshed with the guide rack, a linear guide is connected to the side of the clamping frame away from the guide rack, a slide is slidably installed on the linear guide, and one end of the displacement frame is connected to the slide.

[0008] As a preferred technical solution of the present invention, the deformation component includes a sleeve, which is connected to the front side of the displacement frame, the number of sleeves is several and consistent with the clamping components, and the several clamping components are respectively arranged on the front sides of the several sleeves, and the top surface of the sleeve is provided with two sliding holes, and a guide rod is connected in the sliding hole, and a slider is slidably connected on the guide rod, and the bottom end of the slider is rotatably connected with a rotating shaft, and a connecting pin is connected on the rotating shaft, and the outer end of the connecting pin is connected to the clamping head, and the bottom end of the rotating shaft is connected to a rotating gear, and a deformation rack is sleeved in the sleeve, and gear teeth are provided on both sides of the deformation rack and mesh with two rotating gears at corresponding positions, and control motors are installed at positions corresponding to the several sleeves on the rear side of the displacement frame, and the transmission shaft of the control motor passes through the displacement frame and is connected to the guide rack at the corresponding position, the side and bottom surface of the front end of the sleeve are open, and the inner wall of the top surface of the sleeve is higher than the clamping head, and the displacement frame is connected to a limiting frame above the several sleeves, and a locking motor is installed on the limiting frame, and the transmission shaft of the locking motor is connected to the limiting pin, and the top surfaces of the two sliders at the corresponding positions are connected with a sleeve key.

[0009] As a preferred technical solution of the present invention, a connecting frame is connected to the rear end of the clamping head, 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 limit plate that abuts against the front and rear openings of the sleeve hole, so that the connecting pin is connected to the clamping head, and the rear end of the connecting frame is a curved surface, and the central axis of the curved surface corresponds to the axis center of the rotating shaft.

[0010] As a preferred technical solution of the present invention, the negative pressure exhaust component includes a negative pressure fan, which is installed on left and right frames. The left and right frames are also connected to a filter box, in which a filter plate filled with filter filler is inserted. The air inlet of the negative pressure fan is connected and connected to the bottom side of the filter box through an exhaust pipe 1, the top side of the filter box is connected and connected to an exhaust pipe 2, the rear side of the displacement frame is connected to a concentrating cylinder, a number of air pipes are connected and connected to the exhaust pipe 2, and the free end of the exhaust pipe 2 is connected and connected to the exhaust pipe 2.

[0011] Compared with the prior art, the present invention can achieve the following beneficial effects:

[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 demand for clamping force, and avoiding problems such as material position displacement caused by vibration due to stress after material cutting.

[0013] 2. The vacuum exhaust assembly is used to exhaust and remove dust from the cutting position through the unfolded clamping head. Not only is the vacuum position aligned to the cutting position, but the vacuum effect is also concentrated on the cutting position, which improves the efficiency and effect of removing dust and debris generated by cutting, and prevents dust and debris from adhering to the clamp to avoid affecting the clamping effect and stability.

[0014] 3. Through the characteristics of several clamping heads that can move and change the clamping position, after the material is placed on the cutting table, pressure is automatically applied to the material to achieve clamping. It can automatically adapt to materials of different sizes, thicknesses and shapes, thereby improving the efficiency and effect of clamping.

[0015] 4. By adding several components to the front side of the clamping frame and utilizing the end positions of several clamping heads relative to each other, the clamping heads can be arranged in a staggered or arc shape. When cutting arc-shaped tubes, special-shaped tubes and other materials, the clamping heads can clamp the materials from the front and back in a state that adapts to the shape of the materials. The clamping components can not only clamp plate-shaped materials, but also clamp tubular materials of different shapes, thereby improving the adaptability of the clamping function to different materials. The dust removal functions of the clamping heads are not affected, and the clamping points are kept close to the cutting area for clamping without being affected by the adhesion of dust and debris.

[0016] 5. Through the action of the negative pressure exhaust component on the clamping head, the clamping head in the closed state can fit together more closely, making it more difficult to separate the clamping head when it is subjected to external force, thus maintaining the continuous stability of the state.

[0017] 6. Through the setting of the connecting frame, when the clamping head is opened or closed, the connecting pin will first lift the clamping head away from the material through the sleeve hole to avoid the deformation of the clamping head exerting thrust on the material, thereby ensuring the stability of material clamping.

[0018] 7. Through the setting of the transmission belt, when the displacement assembly drives the clamping head to change its position, the transmission belt runs over the material to avoid friction from pushing the material to move while maintaining the applied pressure. The clamping head in the closed state limits the lateral movement of the material through the transmission belt, and the clamping head in the expanded state limits the longitudinal movement of the material through the transmission belt, thereby ensuring the stability of the plane position of the material.

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work all belong to the protection scope of the present invention. The experimental methods in the following embodiments, unless otherwise specified, are conventional methods, and the materials, reagents, etc. used in the following embodiments, unless otherwise specified, can all be obtained from commercial channels.

[0027] Embodiment: Figure 1-6As shown, an adaptive shock-proof clamping laser cutting machine includes a left and right frame 10 and a front and rear frame 11. The number of the left and right frames 10 and the front and rear frames 11 are both two groups. The two groups of left and right frames 10 are distributed left and right. The two groups of front and rear frames 11 are arranged at the front and rear ends of the corresponding surfaces of the two groups of left and right frames 10. The table tops of the front and rear frames 11 are provided with a cutting material table 12 composed of a plurality of support bars. A cutting work platform 13 is arranged on the left and right frames 10. The cutting work platform 13 adopts a gantry moving platform. The cutting work platform 13 includes a gantry, a walking track 1 that can drive the gantry to move forward and backward, a walking track 2 arranged on the gantry to move left and right, and a lifting track arranged on the walking track 2. It is an existing well-known technology and will not be described in detail here. A laser cutting head 14 for generating laser to achieve cutting is arranged on the lifting track of the cutting work platform 13. The laser cutting head 14 is an existing well-known technology. The left and right frames 10 are composed of an emitter, a cutting head and a beam transmission component, which will not be elaborated here. A control cabinet is also provided on one side of the left and right frames 10, and the equipment can also be installed with components such as a controller and a threading drag chain according to the existing technology. A lifting device 15 is installed on the outer side of the front and rear frames 11. The lifting device 15 adopts a cylinder. The transmission shaft of the lifting device 15 is connected to a clamping frame 16. A number of clamping components are arranged on the clamping frame 16. The clamping component includes two clamping heads 17. The two clamping heads 17 are in a correspondingly fitted state. The corresponding surfaces of the two clamping heads 17 are provided with an exhaust port 18. A negative pressure exhaust component is provided on the front and rear frames 11 at the rear side. The negative pressure exhaust component is connected to the clamping head 17 through an air pipe 19 and is connected to the exhaust port 18. A displacement component for adjusting the position of the clamping component is provided on the clamping frame 16, and 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 started to drive the clamping frame 16 to descend, and the clamping head 17 applies pressure to the material to clamp it. Then, after debugging, measuring and other steps, the cutting work platform 13 drives the laser cutting head 14 to move forward and backward, left and right, and up and down, so that the laser cutting head 14 in the started 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 expand from one side, and the clamping heads 17 at other positions maintain the clamping position. While the cutting position is vacated, the expanded exhaust port 18 starts the negative pressure exhaust component to absorb the dust and debris generated during the cutting process. Then, as the cutting position changes, the deformation component drives the clamping head 17 at the corresponding position to expand, and the clamping head 17 at the non-corresponding position is reset. 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. A number of clamping assemblies 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 adopts a motor with a self-locking function. The transmission shaft of the displacement motor 21 is connected to a driving gear 22. A long hole is opened on one side of the clamping frame 16. The bottom wall of the long hole is connected to a guide rack 23. The driving gear 22 is meshed 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 seat 25 is slidably installed on the linear guide rail 24, and one end of the displacement frame 20 is connected to the slide seat 25.

[0030] Specifically, the displacement motor 21 starts to drive the driving gear 22 to rotate. Depending on the forward and reverse rotations, the driving gear 22 engages with the guide rack 23 to generate thrust on the displacement frame 20, so that the displacement frame 20 can move forward and backward on the clamping frame 16, thereby changing the front and rear 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. The number of sleeves 26 is several and consistent with the clamping assembly. The several clamping assemblies are respectively arranged on the front sides of the several sleeves 26. The front side of the sleeve 26 is a rectangular frame. The top surface of the sleeve 26 is provided with two sliding holes 27 distributed on the left and right. A guide rod 28 is connected in 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 through a rotating bearing. The rotating shaft 30 is connected to a T-shaped connecting pin 31. The outer end of the connecting pin 31 It is connected to the clamping head 17, and a rotating gear 32 is connected to the bottom end of the rotating shaft 30. A deformable rack 33 is sleeved in the sleeve 26. Gear teeth are provided on both sides of the deformable rack 33 and mesh with the two rotating gears 32 at corresponding positions. Control motors 34 are installed at the positions corresponding to several sleeves 26 on the rear side of the displacement frame 20. The control motor 34 adopts a telescopic motor. The transmission shaft of the control motor 34 passes through the displacement frame 20 and is connected to the guide rack 23 at the corresponding position. The side and bottom surfaces of the front end 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 deformation rack 33 to move forward and backward. When the deformation rack 33 moves forward, the deformation rack 33 drives the rotating gear 32 to rotate, so that the two clamping heads 17 connected by the connecting pin 31 are expanded outward. When the deformation rack 33 moves backward, the clamping heads 17 in the expanded state are closed, thereby controlling the expansion and closing of the clamping heads 17. When the negative pressure exhaust component is started, in order to ensure the strength of exhaust dust removal, the power of the negative pressure exhaust component is much greater than the ventilation volume of the exhaust port 18 in the expanded state, so that the two closed clamping heads 17 are closely attached to each other due to the negative pressure. Therefore, when the deformation rack 33 moves forward and backward, the rotation of the rotating gear 32 is resisted, and the deformation rack 33 will drive the rotating gear 32 to slide in the sliding hole 27, thereby driving the clamping heads 17 to slide back and forth on the sleeve 26, changing a number of groups The position of the clamping head 17 is adjusted, 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, so that the clamping head 17 can be arranged in a staggered or arc shape. Therefore, when cutting materials such as arc tubes and special-shaped tubes, after installing a displacement component, a clamping component, a deforming component and a negative pressure exhaust component on the front side of the clamping frame 16 (not shown in the figure), the position of the clamping head 17 is changed to adapt to the shape of the material, and then the material is clamped from the front and back sides, so that the material can be clamped stably, and the clamping head 17 can perform the exhaust and dust removal function in the same way 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 cannot continue to move, and the deformable rack 33 can continue to slide to apply a rotational thrust greater than the negative pressure, thereby driving the clamping head 17 to implement the expansion or closing function.

[0033] like Figure 2 As shown, the displacement frame 20 is connected to a limit frame 35 above a plurality of sleeves 26, and a locking motor 36 is installed on the limit frame 35. The locking motor 36 adopts a telescopic motor, and the drive shaft of the locking motor 36 is connected to a limit pin 37. The limit pin 37 is C-shaped and the concave surface 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 with a sleeve key 38, and the sleeve key 38 is adapted to the concave surface of the limit pin 37.

[0034] Specifically, when the deforming 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 insert the insertion key 38, thereby limiting the position of the slider 29. Then, when the deforming rack 33 moves forward and backward, it will drive the clamping head 17 to expand or merge, so that the deformation position of the clamping head 17 is limited to the rear side position of the sleeve 26, avoiding the expansion or closing of the clamping head 17 and contact with the material.

[0035] like Figure 5As shown, an annular groove is provided at the center of the clamping head 17, a toothed roller 39 is connected to the annular groove via a rotating bearing, a toothed transmission belt 40 is sleeved on the toothed roller 39, and the transmission belt 40 is made of high temperature resistant material.

[0036] Specifically, when the clamping head 17 moves forward and backward, the transmission belt 40 contacts the material and operates, thereby reducing the friction between the clamping head 17 and the material, avoiding problems such as the clamping head 17 being worn or causing the material to deviate.

[0037] like Figure 5 As shown, the rear end of the clamping head 17 is connected to a connecting frame 41, and a V-shaped sleeve hole 42 is opened on the rear side of the connecting frame 41. The end of the connecting pin 31 is sleeved in the sleeve hole 42, and the end of the connecting pin 31 is connected to a limit 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 a curved surface, and the central axis of the curved surface corresponds to the axis of the rotating shaft 30.

[0038] Specifically, when the deformed rack 33 drives the rotating gear 32 to rotate, because the clamping head 17 contacts the material and there is a certain resistance between the clamping head 17 and the material, the connecting pin 31 will first slide in the sleeve hole 42 and lift the clamping head 17 along the hole wall of the sleeve hole 42. Then, after the clamping head 17 is out of close contact with the material, the connecting pin 31 pushes the clamping head 17 along the inclined surface of the sleeve hole 42 to close or expand. After the clamping head 17 is closed or expanded to the limit position, the connecting pin 31 slides in the sleeve hole 42 again and pushes the clamping head along the inclined surface. 17 descends, so that the clamping head 17 is tightly in contact with the material, restricting the longitudinal movement of the material, while the clamping head 17 in the closed state restricts the lateral movement of the material. It should be noted that in the process of unfolding the clamping head 17, the power of the negative pressure exhaust component is appropriately reduced to make the clamping head 17 easy to unfold. 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. The left and right frames 10 are also connected to a filter box 45. A filter plate 46 filled with filter filler is inserted into the filter box 45. The air inlet of the negative pressure fan 44 is connected to and communicated with the bottom side of the filter box 45 through an exhaust pipe 1 47, and the top side of the filter box 45 is connected to and communicated with an exhaust pipe 2 48. A concentrating cylinder 49 is connected to the rear side of the displacement frame 20, and a number of air pipes 19 are connected to and communicated with the exhaust pipe 2 48. The free end of the exhaust pipe 2 48 is connected to and communicated with the exhaust pipe 2 48.

[0040] Specifically, after the negative pressure fan 44 is started, the suction function is applied to the concentration tube 49 through the path of the suction pipe 1 47 and the suction pipe 2 48, and then dispersed to a number of air pipes 19 through the concentration tube 49, so that the suction port 18 generates a negative pressure suction function, and the air flow drawn into the negative pressure fan 44 is filtered through the filter plate 46 to avoid polluting the external environment and ensure the service life of the negative pressure fan 44.

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

[0042] It should be noted that the structural motion control of the present application is achieved by setting up sensors, which is a well-known technology and will not be elaborated here.

[0043] Working principle:

[0044] Before use: place the material to be cut on the cutting table 12, start the lifting device 15 to drive the clamping frame 16 to descend, apply pressure to the material to clamp it, and then after debugging, measuring and other steps, the cutting work platform 13 drives the laser cutting head 14 to move forward and backward, left and right, and up and down, so that the laser cutting head 14 in the started state can cut the material into the required shape.

[0045] When in use: the first step is to let the control motor 34 corresponding to the cutting position control the deformation rack 33 to move backward, pull the clamping head 17 to move backward, and after reaching the limit, the deformation component controls the clamping head 17 to unfold behind the cutting position, and then start the negative pressure exhaust component to absorb the dust and debris generated by the 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, and the clamping head 17 located at the subsequent cutting position is unfolded 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 that has left the cutting position to close at the rear first, and then move forward to the clamping point.

[0047] In the third step, after a row of horizontal cutting is completed, the negative pressure exhaust component is turned off, the deformation component closes and resets the unfolded clamping head 17, and then the displacement component drives the clamping head 17 to move as a whole to the next row, and then the first and second steps are repeated.

[0048] The fourth step is to install a clamping assembly, a displacement assembly, a deformation assembly and a negative pressure exhaust assembly on the front side of the clamping frame 16 when cutting materials such as profiles, arc-shaped tubes and special-shaped tubes. After the clamping head 17 close to the cutting position is unfolded in advance, the deforming rack 33 pushes the closed clamping head 17 to move, and the position of the clamping head 17 is changed to adapt to the shape of the material. The material is then clamped from the front and back sides to stably clamp the material.

[0049] After use: the unfolded clamping head 17 is reset, and the lifting device 15 pushes the clamping frame 16 to lift up and separate from the material, so as to facilitate material removal.

[0050] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
