Description

Technical Field

[0001] This invention belongs to the field of laser processing equipment technology, specifically relating to a three-dimensional laser cutting device, and more particularly to a three-dimensional laser cutting machine with alternating up and down operation function, capable of self-calibrating the horizontality of the moving stage and precise positioning. Background Technology

[0002] Laser cutting technology, with its advantages of high precision, high speed, and small heat-affected zone, has become one of the core technologies for sheet metal processing in modern manufacturing, and corresponding laser cutting equipment has been widely used. However, existing laser cutting machines still face many problems that urgently need to be solved in practical applications:

[0003] 1. Limited processing efficiency: Traditional laser cutting machines mostly adopt a single worktable design. After a batch of plates is cut, the machine needs to be stopped to unload the processed plates and reload and fix them. During this process, the laser cutting mechanism is idle, and there is a significant waiting time, which seriously affects the overall processing efficiency and makes it difficult to meet the needs of large-scale mass production.

[0004] 2. The moving table is prone to level deviation: Laser cutting requires extremely high levelness of the worktable. Deviations in worktable levelness directly lead to problems such as tilted cut surfaces and exceeding dimensional accuracy limits. Currently, most laser cutting machines use moving tables that slide directly along guide rails. Over time, wear on the guide rails and uneven stress on the worktable can easily cause levelness deviations. Furthermore, the impact of the material on the worktable during loading can also cause momentary levelness fluctuations. Existing equipment lacks an effective real-time levelness calibration mechanism, requiring periodic manual calibration, which is not only cumbersome but also further increases downtime and affects production continuity.

[0005] 3. Insufficient positioning accuracy of the moving stage: The displacement positioning accuracy of the moving stage directly determines the positional accuracy of the sheet metal cutting. Existing equipment mostly relies on hydraulic cylinders or motors to directly drive the moving stage for positioning, lacking multi-stage linkage for precise limit and locking mechanisms. After long-term, high-frequency reciprocating motion, the cumulative error of the drive components will lead to an increase in the positioning deviation of the moving stage; moreover, some positioning mechanisms are prone to springback or loosening after locking, further reducing the cutting accuracy.

[0006] 4. Poor operational stability: Some existing cutting equipment with multiple worktables have complex transmission and limit mechanisms, poor coordination between components, and are prone to jamming and abnormal noise during alternating operations. At the same time, the lack of effective buffering and reset mechanisms results in large impact forces during equipment start-up, shutdown, and switching, which not only affects the service life of components but also indirectly affects processing accuracy.

[0007] Based on the shortcomings of the existing technology, there is an urgent need for a laser cutting device that can achieve efficient alternating operations, has real-time level calibration function, precise positioning and stable operation, so as to make up for the deficiencies of the existing technology. Summary of the Invention

[0008] The purpose of this invention is to provide a three-dimensional laser cutting machine capable of alternating up and down movement and its usage method, in order to solve the problem of easy deviation in the horizontality of the moving stage in existing devices mentioned in the background art. To achieve the above objective, this invention provides the following technical solution: a three-dimensional laser cutting machine capable of alternating up and down movement, comprising a fixed support and a moving stage slidably mounted on the fixed support, spring buffer rollers installed on both sides of the bottom of the moving stage, deflection plates movably sleeved on the spring buffer rollers on the same side, a push block being engaged at the top of the deflection plate, and the push block being fixed to the side of the moving stage;

[0009] The bottom of the four deflection plates is hinged with connecting rods. The lower end of the rightmost deflection plate is fixedly connected to a roller, and an inclined frame is fitted on the outside of the roller. The movement of the moving stage drives the roller to move along the inclined frame, causing the deflection plate to deflect and push the push block to move the moving stage slightly upward, thereby calibrating the level of the moving stage.

[0010] Preferably, a laser cutting machine is mounted on the fixed bracket. Four support rods are fixedly connected to the inner side of the fixed bracket, with the four support rods arranged in pairs, staggered vertically. Spring-loaded buffer rollers on the moving platform slide on the two sets of support rods. A hydraulic cylinder is provided on the moving platform, with the other end of the hydraulic cylinder fixed to the fixed bracket. The two moving platforms can slide alternately under the drive of the hydraulic cylinder.

[0011] Preferably, a floating joint is installed at the end of the hydraulic cylinder, and the hydraulic cylinder is fixedly connected to the moving platform through the end floating joint.

[0012] Preferably, an L-shaped card frame is fixedly connected to the right side of the inclined frame. An arc groove is provided on the L-shaped card frame. A deflection pressure rod is fixedly connected to the side of the rightmost deflection card plate. The arc groove and the deflection pressure rod work together. After the deflection pressure rod is inserted into the arc groove, it can push the L-shaped card frame to move synchronously.

[0013] Preferably, an L-shaped limiting block is slidably connected to the inner side of the L-shaped card frame, and a reset spring telescopic rod is fixedly connected between the bottom of the L-shaped limiting block and the inner side of the L-shaped card frame. A limiting stop is provided on the outer side of the L-shaped limiting block, and a notch is opened on the limiting stop for the L-shaped limiting block to pass through. The limiting stop is fixed on the inner wall of the fixed bracket.

[0014] Preferably, an inner plate is fixedly connected to the right side of the L-shaped card frame, and an inclined plate is fixedly connected to the middle of the inner plate. Guide grooves are provided on both the upper and lower sides of the inner plate. A first sleeve is fitted on the outer side of the inner plate and is fixed to the inner wall of the fixed bracket. Through grooves are provided on both the upper and lower sides of the middle of the first sleeve. First spring telescopic rods are fixedly connected to the front and rear sides of the inner wall of the through grooves. An inverted U-shaped limiting plate is fixedly connected between the two first spring telescopic rods. A pressure rod is fixedly connected to the bottom of the inner wall of the inverted U-shaped limiting plate, and the pressure rod cooperates with the inclined plate.

[0015] Preferably, a second sleeve is movably sleeved on the outer side of the first sleeve, and a second spring telescopic rod is fixedly connected between the left end of the inner wall of the second sleeve and the left end of the first sleeve. Slots are provided on both the upper and lower sides of the second sleeve. Two L-shaped transmission plates are symmetrically fixedly connected to the right end of the second sleeve. The ends of the two L-shaped transmission plates away from the second sleeve respectively abut against the upper and lower sides of the inner plate. A push block abuts against the inner side of the L-shaped transmission plate, and the push block is fixed on the upper and lower sides of the inner plate.

[0016] Preferably, the deflection rod is composed of a guide rod and an L-shaped rod connected together, and the guide rod and the L-shaped rod are staggered; a guide slide rail is horizontally fixed on the inner wall of the fixed bracket, and the guide rod can slide on the guide slide rail after deflection.

[0017] A method for using a three-dimensional laser cutting machine capable of alternating up and down movements includes the following steps:

[0018] S1: The sheet material is placed on the moving table, and the hydraulic cylinder drives it to move. The spring buffer rollers roll on the support rod, sending the moving table to the bottom of the laser cutting machine. When the moving table moves to the right, the rollers enter the horizontal and oblique channels of the inclined frame in turn, driving the deflection plate to turn from oblique to vertical, pushing the push block to move the moving table up to calibrate the levelness and ensure the cutting quality.

[0019] S2: The deflection plate deflects, causing the guide rod to turn horizontally, the L-shaped pressure rod to engage in the arc groove and squeeze the L-shaped limit block to move downward, and the reset spring telescopic rod is compressed; the moving table continues to move, causing the inclined frame and other components to move to the right synchronously, and the guide rod enters the guide rail for stabilization; the inner plate drives the push block to push the L-shaped transmission plate and the second sleeve to move, and after the slot is aligned with the inverted U-shaped limit plate, the inverted U-shaped limit plate engages in the slot under the action of the first spring telescopic rod, achieving precise positioning;

[0020] S3: Cutting is completed. The hydraulic cylinder drives the moving table to reset. Another hydraulic cylinder drives another moving table to move to the right to achieve alternating operation. When the moving table moves to the left, the inner plate drives the inclined plate to squeeze the pressure bar. The inverted U-shaped limit plate disengages from the slot, and the second sleeve resets under the action of the second spring telescopic rod.

[0021] S4: The L-shaped frame drives the L-shaped limit block to stop moving after it comes into contact with the limit block. The moving table continues to move, causing the deflection plate to deflect around the roller as the center. The deflection pressure rod disengages from the arc groove, and the L-shaped limit block resets and locks the L-shaped frame. The roller disengages from the inclined frame, and the moving table can be replaced after it resets.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] This invention significantly improves processing efficiency: By setting up two sets of vertically staggered moving platforms and using hydraulic cylinders to drive them to slide alternately, one moving platform can perform cutting operations under the laser cutting machine while the other moving platform can simultaneously perform loading or unloading operations. This completely eliminates the loading and unloading waiting time of traditional single-workbench equipment, enabling parallel cutting and loading / unloading operations. It significantly improves the continuous operation capability and overall processing efficiency of the equipment, and is especially suitable for mass production scenarios.

[0024] This invention features an automatic calibration mechanism for the moving stage's levelness, ensuring cutting accuracy. The mechanism, comprised of spring-loaded buffer rollers, a deflection plate, a push block, a connecting rod, rollers, and an inclined frame, automatically calibrates the levelness of the moving stage during its movement. When the moving stage moves to the right, the rollers enter the inclined channel of the inclined frame, causing the deflection plate to deflect and subsequently pushing the push block and the moving stage slightly upwards, achieving real-time levelness calibration. Simultaneously, the spring-loaded buffer rollers effectively cushion the impact of the sheet material on the moving stage during loading, preventing instantaneous levelness fluctuations. This design requires no manual intervention to continuously ensure the moving stage's levelness, fundamentally solving the cutting accuracy problem caused by levelness deviations and improving the stability of sheet material cutting quality.

[0025] This invention offers high positioning accuracy and stable operation. Firstly, the L-shaped frame, arc groove, and deflection rod work together to achieve synchronous linkage between the moving stage and the leveling calibration mechanism. Secondly, the positioning mechanism, composed of an inner plate, inclined plate, guide groove, sleeve assembly (first sleeve and second sleeve), inverted U-shaped limiting plate, and spring telescopic rod, accurately positions the rightward movement distance of the inner plate and the moving stage. When the slot of the second sleeve aligns with the inverted U-shaped limiting plate, the inverted U-shaped limiting plate engages with the slot under the action of the first spring telescopic rod, achieving precise positioning of the moving stage. Simultaneously, the cooperation between the L-shaped limiting block and the limiting stop locks the L-shaped frame, preventing it from springing back and loosening, further ensuring positioning accuracy.

[0026] This invention features excellent mechanism coordination and a long service life: Through components such as the deflection pressure rod, L-shaped frame, inner plate, and L-shaped transmission plate, this invention achieves multi-level linkage between the moving stage, calibration mechanism, and positioning mechanism. The smooth connection between the actions of each component avoids jamming problems caused by independent drives. Simultaneously, multiple buffering and reset components, such as the spring buffer roller, reset spring telescopic rod, and second spring telescopic rod, effectively absorb impact forces during equipment operation, reduce component wear, and extend the overall service life of the equipment.

[0040] 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.

[0041] Please see Figures 1 to 12 This invention provides a technical solution: a three-dimensional laser cutting machine capable of alternating vertical movement, comprising a fixed support 1, on which a laser cutting machine 2 is mounted. Four support rods 3 are fixedly connected to the inner side of the fixed support 1, arranged in pairs with staggered vertical alignment. Moving stages 4 are slidably mounted on each pair of support rods 3. Hydraulic cylinders 5 are mounted on the moving stages 4, with the other end of each hydraulic cylinder 5 fixed to the fixed support 1. The two moving stages 4 slide alternately, cooperating with the laser cutting machine 2 to cut the sheet metal on the two moving stages 4. A floating joint is installed at the end of the hydraulic cylinder 5, and this floating joint is fixedly connected to the moving stage 4, ensuring that the moving stage 4 can subsequently move slightly upwards to achieve the purpose of leveling the moving stage 4.

[0042] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 12 As shown, four spring-loaded buffer rollers 41 are installed on both sides of the bottom of the moving platform 4. The moving platform 4 moves on the support rod 3 by sliding on the spring-loaded buffer rollers 41. Each of the four spring-loaded buffer rollers 41 on the same side is movably fitted with a deflection plate 42. Each of the four deflection plates 42 has a push block 43 locked on its top, and the push block 43 is fixed to the side of the moving platform 4. By deflecting the four deflection plates 42 in conjunction with the connecting rod 44, the moving platform 4 can be pushed slightly upward to calibrate the levelness of the moving platform 4.

[0043] The bottom of the four deflection plates 42 is hinged with a connecting rod 44. A roller 45 is fixedly connected to the right end of the rightmost deflection plate 42. An inclined frame 46 is sleeved on the outside of the roller 45. An L-shaped frame 47 is fixedly connected to the right side of the inclined frame 46. An arc groove 48 is opened on the L-shaped frame 47, and the arc groove 48 is used in conjunction with the deflection pressure rod 49 fixedly connected to the side of the rightmost deflection plate 42. After the deflection pressure rod 49 is inserted into the arc groove 48, it can push the L-shaped frame 47 to move to the right synchronously.

[0044] An L-shaped limiting block 410 is slidably connected to the inner side of the L-shaped frame 47. A reset spring telescopic rod 411 is fixedly connected between the bottom of the L-shaped limiting block 410 and the inner side of the L-shaped frame 47. A limiting stop 412 is provided on the outer side of the L-shaped limiting block 410, and a notch for the L-shaped limiting block 410 to pass through is provided on the limiting stop 412. When the L-shaped limiting block 410 moves upward and resets under the action of the reset spring telescopic rod 411, its end abuts against the inner end face of the limiting stop 412, thereby restricting the L-shaped frame 47 from moving to the left.

[0045] The limiting block 412 is fixed on the inner wall of the fixed bracket 1, and the limiting block 412 is on the inner side of the L-shaped frame 47.

[0046] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 12 As shown, an inner plate 6 is fixedly connected to the right side of the L-shaped card frame 47, and an inclined plate 61 is fixedly connected to the middle of the inner plate 6. Guide grooves 62 are provided on both the upper and lower sides of the inner plate 6; the inner plate 6 is H-shaped.

[0047] The outer side of the inner plate 6 is fitted with a first sleeve 63, and the right end of the first sleeve 63 is fixed to the inner wall of the fixed bracket 1. The upper and lower sides of the middle of the first sleeve 63 are provided with through grooves 64. The front and rear sides of the inner wall of the through groove 64 are fixedly connected with first spring telescopic rods 65. An inverted U-shaped limiting plate 66 is fixedly connected between the two first spring telescopic rods 65. The inverted U-shaped limiting plate 66 is vertically slidably arranged in the through groove 64.

[0048] A pressure rod 67 is fixedly connected to the bottom of the inner wall of the inverted U-shaped limiting plate 66. The pressure rod 67 is pressed into the guide groove 62 by the inclined surface of the inclined plate 61.

[0049] A second sleeve 68 is movably fitted on the outer side of the first sleeve 63. A second spring telescopic rod 69 is fixedly connected between the left end of the inner wall of the second sleeve 68 and the left end of the first sleeve 63. Slots 610 are provided on both the upper and lower sides of the second sleeve 68. L-shaped blocks are fixedly connected to the upper and lower sides of the inner plate 6, and the vertical blocks of the L-shaped blocks abut against the inner wall of the second sleeve 68 to ensure the stability of the inner plate 6 sliding inside the second sleeve 68.

[0050] Two L-shaped transmission plates 611 are symmetrically fixedly connected to the right end of the second sleeve 68. The ends of the two L-shaped transmission plates 611 away from the second sleeve 68 respectively abut against the upper and lower sides of the inner plate 6. The inner sides of the two L-shaped transmission plates 611 abut against the push blocks 612, and the two push blocks 612 are fixed on the upper and lower sides of the inner plate 6 respectively. The movement of the inner plate 6, in coordination with the push blocks 612, drives the L-shaped transmission plates 611 and the second sleeve 68 to move to the right at the same time.

[0051] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 12 As shown, the deflection rod 49 is composed of a guide rod 491 and an L-shaped rod 492 connected together, and the guide rod 491 and the L-shaped rod 492 are staggered. There is a guide rail 7 on the right side of the guide rod 491, and the guide rail 7 is horizontally fixed on the inner wall of the fixed bracket 1. By staggering the guide rod 491 and the L-shaped rod 492, it is ensured that the deflected guide rod 491 slides horizontally on the guide rail 7.

[0052] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 12 As shown, the spring buffer roller 41 is composed of a roller and a spring buffer connected together, and is used to buffer the impact force of the material on the moving table 4 during feeding.

[0053] A serrated plate 8 is detachably installed on the moving platform 4.

[0054] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 12 As shown, a limiting slide rail 9 is fixedly connected to the side of the support rod 3 to ensure that the spring buffer roller 41 slides stably against the support rod 3.

[0055] The method of use and advantages of this invention: The working process of this three-dimensional laser cutting machine that can achieve alternating up and down movements is as follows:

[0056] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 12 As shown, the plate to be laser-cut is placed on the moving table 4, and then the moving table 4 is moved by the hydraulic cylinder 5, causing the spring buffer roller 41 to roll on the support rod 3, moving the moving table 4 carrying the plate to below the laser cutting machine 2, so that the laser cutting machine 2 can cut the plate on the moving table 4 in the future.

[0057] As the moving stage 4 moves to the right, the rightmost roller 45 moves into the transverse channel inside the inclined frame 46. As the moving stage 4 continues to move to the right, the roller 45 moves into the inclined channel of the inclined frame 46, thereby causing the deflection plate 42 to deflect from an inclined state to a vertical state. During this process, the push block 43 is pushed slightly upward to calibrate the levelness of the moving stage 4, ensuring the levelness of the plate on the moving stage 4, and thus ensuring the quality of the subsequent cutting of the plate by the laser cutting machine 2.

[0058] During the process of the deflection plate 42 deflecting from the inclined state to the vertical state, the guide rod 491 is driven to deflect from the inclined state to the horizontal state, the L-shaped pressure rod 492 deflects and is inserted into the arc groove 48, and the L-shaped limit block 410 is pressed to move down. At this time, the reset spring telescopic rod 411 is compressed to facilitate the subsequent rightward movement of the L-shaped limit block 410 and its disengagement from the inside of the limit block 412. Then, as the moving table 4 continues to move to the right, the inclined frame 46, the L-shaped clamping frame 47, the guide rod 491 and the inner plate 6 move to the right at the same time. At this time, the guide rod 491 enters the guide slide rail 7, further ensuring the stability of the rightward movement of the guide rod 491.

[0059] Furthermore, the inner plate 6 drives the push block 612 to move to the right, thereby pushing the L-shaped transmission plate 611 and the second sleeve 68 to move to the right simultaneously. When the slot 610 on the second sleeve 68 moves to the right and is on the same vertical plane as the inverted U-shaped limiting plate 66, the inverted U-shaped limiting plate 66 moves upward and is inserted into the slot 610 under the action of the first spring telescopic rod 65, accurately positioning the distance of the inner plate 6 to move to the right, thereby ensuring the accuracy of the distance of the moving table 4 to move to the right.

[0060] After the laser cutting machine 2 finishes cutting the material on the moving table 4, the hydraulic cylinder 5 retracts to reset the moving table 4, and another hydraulic cylinder 5 moves the other moving table 4 to the right, realizing the staggered left and right replacement of the two moving tables 4, ensuring the efficiency of the laser cutting machine 2 in processing the material on the two moving tables 4.

[0061] When the hydraulic cylinder 5 retracts and drives the moving platform 4 to move to the left to reset, it causes the inner plate 6 to slide inside the second sleeve 68, causing the inclined plate 61 to press the pressure rod 67, which in turn causes the inverted U-shaped limiting plate 66 to move down and be pulled out from the slot 610. At this time, under the action of the second spring telescopic rod 69, the second sleeve 68 moves to the left on the first sleeve 63, causing the slot 610 and the inverted U-shaped limiting plate 66 to be misaligned.

[0062] When the inner plate 6 moves to the left, the L-shaped frame 47 drives the L-shaped limit block 410 to reset and abut against the inner side of the limit block 412. At this time, the L-shaped frame 47 cannot continue to move to the left.

[0063] When the hydraulic cylinder 5 continues to drive the moving table 4 to move to the left, the roller 45 at the end of the rightmost deflection plate 42 is located inside the inclined frame 46 and cannot move. This causes the rightmost deflection plate 42 to deflect around the central axis of the roller 45, causing the deflection rod 49 to move out of the arc groove 48. At this time, the L-shaped limit block 410 is reset and moves upward under the action of the reset spring telescopic rod 411 to abut against the limit block 412, locking the position of the L-shaped frame 47.

[0064] Hydraulic cylinder 5 continues to drive the moving table 4 to move to the left, causing the roller 45 to move out of the inclined frame 46, completing the separation of the two. After the moving table 4 moves to the left and resets, the processed plate on the moving table 4 can be replaced.

[0065] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.

9. A method of using a three-dimensional laser cutting machine capable of alternating up and down movements, comprising using a three-dimensional laser cutting machine capable of alternating up and down movements as described in any one of claims 1-8, characterized in that, Includes the following steps: S1. The plate is placed on the moving table (4), and the hydraulic cylinder (5) drives it to move. The spring buffer roller (41) rolls on the support rod (3) to send the moving table (4) to the bottom of the laser cutting machine (2). When the moving table (4) moves to the right, the roller (45) enters the horizontal and oblique channels of the inclined frame (46) in turn, driving the deflection plate (42) to turn from oblique to vertical, pushing the push block (43) to move the moving table (4) up to calibrate the levelness and ensure the cutting quality. S2: The deflection plate (42) deflects and drives the guide rod (491) to turn horizontally, the L-shaped pressure rod (492) is inserted into the arc groove (48) and squeezes the L-shaped limit block (410) to move down, and the reset spring telescopic rod (411) is compressed; the moving table (4) continues to move and drives the inclined frame (46) and others to move to the right in sync, and the guide rod (491) enters the guide slide rail (7) to stabilize; the inner plate (6) drives the push block (612) to push the L-shaped transmission plate (611) and the second sleeve (68) to move, and after the slot (610) is aligned with the inverted U-shaped limit plate (66), the inverted U-shaped limit plate (66) is inserted into the slot (610) under the action of the first spring telescopic rod (65) to achieve precise positioning; S3: Cutting is completed.
