Description

Technical Field

[0001] This invention relates to the field of laser cutting, and more specifically to a thickness adaptation quality control device for laser cutting of metal sheets. Background Technology

[0002] Laser cutting, as a mainstream process for metal sheet processing, directly impacts cutting accuracy and cross-sectional quality when cutting sheets of varying thicknesses, due to the stability of the workpiece clamping. Currently, conventional laser cutting equipment often employs single-sided or single-point clamping structures, achieving only fixation in one direction and failing to simultaneously clamp both horizontally and vertically. This leads to issues such as vibration, warping, and misalignment of the sheet metal during high-power laser cutting. Furthermore, when dealing with sheets of different specifications, frequent fixture changes or manual adjustment of the clamping position are necessary, resulting in cumbersome processes and poor adaptability. This not only reduces processing efficiency but also easily causes indentations and deformation on the sheet surface due to uneven clamping force, affecting the finished product yield. In addition, some equipment uses rigid clamping components that cannot conform to the subtle undulations of the sheet surface. Unclamped areas are prone to thermal deformation during cutting, making it difficult to meet the demands of high-precision, high-quality cutting.

[0003] Therefore, it is necessary to invent a thickness-adaptive quality control device for laser cutting of metal sheets. Summary of the Invention

The bottom of the frame is provided with a drive mechanism, which includes a slide fixedly connected to the transverse clamping component and a toothed plate drivenly connected to the longitudinal clamping component. The drive mechanism drives the transverse clamping component to move horizontally through the slide and drives the longitudinal clamping component to move vertically through the toothed plate, thereby realizing the synchronous clamping action of the transverse clamping component and the longitudinal clamping component.

[0006] Preferably, the drive mechanism includes a motor fixedly installed at one end of the bottom of the frame, the output shaft of the motor is fixedly connected to a screw a, the screw a passes through the slide and is threadedly connected to the slide, the slide passes through the frame and is slidably connected to the frame, connecting frames are fixedly connected to both the front and rear sides of the slide, and a telescopic adjustment unit is fixedly connected to the end of the connecting frame, the end of the adjustment unit is fixedly connected to the toothed plate.

[0007] Preferably, the adjustment unit includes a main rod fixedly connected to the end of the connecting frame and a secondary rod slidably sleeved inside the main rod. The end of the secondary rod is fixedly connected to the toothed plate. Several pin holes are evenly distributed axially inside the secondary rod.

A spring a is fixedly connected between the base plate and the base, and the spring a is sleeved on the outside of the sliding column.

[0010] Preferably, the longitudinal clamping assembly includes a top plate located inside the bracket, and a plurality of evenly distributed floating clamping units are provided inside the top plate. Slider blocks are fixedly connected to both the front and rear sides of the top plate. Two sliders are slidably embedded in the sliding grooves on the front and rear sides of the bracket, respectively. A screw b is threadedly connected to the slider. The bottom end of the screw b extends to the bottom of the bracket and is fixedly connected to a gear. The gear is located on one side of the gear plate and meshes with the gear plate.

[0011] Preferably, the floating clamping unit includes a circular groove formed at the bottom of the top plate, a spring b is fixedly embedded inside the circular groove, and a pressure head is fixedly connected to the end of the spring b, with the pressure head slidably connected to the circular groove.

It can quickly adapt to metal plates of different lengths without changing the clamps. The adjustment operation is simple and quick, effectively improving the changeover efficiency and versatility of cutting multi-specification plates. Attached Figure Description

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] See attached document Figure 1 -Appendix Figure 6 The present invention provides a thickness adaptation quality control device for laser cutting of metal sheets, comprising a frame 1, with a bracket 2 and a fixed clamp 3 mounted on the top of one end of the frame 1, a movable laser cutting head 4 disposed inside the bracket 2, a horizontally movable transverse clamping assembly disposed on the top of the other end of the frame 1, and a vertically movable longitudinal clamping assembly disposed inside the bracket 2; the laser cutting head 4 moves smoothly inside the bracket 2 via an electric slide rail to perform linear cutting on the workpiece.

[0024] The bottom of the frame 1 is equipped with a drive mechanism, which includes a slide 5 fixedly connected to the transverse clamping component and a toothed plate 6 drivenly connected to the longitudinal clamping component. The drive mechanism drives the transverse clamping component to move horizontally through the slide 5, and at the same time drives the longitudinal clamping component to move vertically through the toothed plate 6, so as to realize the synchronous clamping action of the transverse clamping component and the longitudinal clamping component. In this embodiment, the workpiece to be processed is placed on the frame 1, and its processing area is located at the bottom of the laser cutting head 4. The drive mechanism enables the transverse clamping component and the longitudinal clamping component to clamp the workpiece synchronously, thereby completing the clamping and locking of the workpiece, preventing the workpiece from vibrating during cutting, thus ensuring a flat cutting surface and guaranteeing cutting quality.

[0025] Please refer to the attached document for details. Figure 2To facilitate driving, the device employs the following technical solution: The driving mechanism includes a motor 7 fixedly installed at one end of the bottom of the frame 1. The output shaft of the motor 7 is fixedly connected to a screw a8, which passes through a slide block 5 and is threadedly connected to the slide block 5. The slide block 5 passes through the frame 1 and is slidably connected to the frame 1. Connecting frames 9 are fixedly connected to both the front and rear sides of the slide block 5. A retractable adjustment unit is fixedly connected to the end of the connecting frame 9, and the end of the adjustment unit is fixedly connected to the toothed plate 6. The two ends of the screw a8 are movably connected to the frame 1 via bearings. In actual operation, the motor 7 drives the screw a8 to rotate, thereby causing the slide block 5 to translate. The connecting frame 9 then drives the retractable adjustment unit and the toothed plate 6 to move, thus simultaneously driving the longitudinal pressing component while driving the transverse pressing component.

[0026] Please refer to the attached document for details. Figure 5 To achieve the adjustment purpose, the device adopts the following technical solution: The adjustment unit includes a main rod 10 fixedly connected to the end of the connecting frame 9 and a secondary rod 11 slidably sleeved inside the main rod 10. The end of the secondary rod 11 is fixedly connected to the toothed plate 6. Several pin holes 1101 are evenly distributed axially inside the secondary rod 11. A pin 12 is inserted on the main rod 10, and the pin 12 passes through one of the pin holes 1101 on the secondary rod 11. When it is necessary to process workpieces of different lengths, the position of the secondary rod 11 inside the main rod 10 can be adjusted to change the overall length of the adjustment unit. The length of the adjustment unit is locked by the pin 12, so that it can be adapted to the length of the workpiece to be processed, so as to ensure that the drive mechanism can drive the transverse clamping component and the longitudinal clamping component synchronously. Specifically, when the workpiece is long, the adjustment unit can be shortened, and vice versa, for use in combination.

[0027] Please refer to the attached document for details. Figure 5 In order to achieve the purpose of smooth movement of the adjustment unit, the device adopts the following technical solution: the top of the auxiliary rod 11 and the toothed plate 6 are both fixedly connected to the slide rail 13. The slide rail 13 is T-shaped and is embedded in the bottom of the frame 1 and slidably connected to the frame 1. When the slide block 5 drives the adjustment unit to move through the connecting frame 9, the design of the slide rail 13 can effectively ensure the smooth movement of the adjustment unit and the toothed plate 6.

[0028] Please refer to the attached document for details. Figure 1To achieve the purpose of lateral clamping, the device employs the following technical solution: The lateral clamping assembly includes a base 14 fixedly installed on the top of the slide block 5. A movable clamp 15 is provided on the side of the base 14 near the bracket 2. Two symmetrically distributed sliding columns 16 are fixedly connected to the side of the movable clamp 15 near the base 14. The two sliding columns 16 penetrate the base 14 and are slidably connected to the base 14. A base plate 17 is fixedly connected to the end of the sliding column 16. A spring a18 is fixedly connected between the base plate 17 and the base 14. Furthermore, spring a18 is sleeved on the outside of slide column 16; in actual use, one end of the workpiece abuts against the fixed clamp 3, and the other end is pressed by the transverse pressing assembly. That is, when slide column 5 moves, it drives base 14 to move. When base 14 approaches the workpiece, movable clamp 15 will first contact the workpiece. At this time, base 14 continues to move, and movable clamp 15 will approach base 14. At the same time, slide column 16 moves inside base 14, and spring a18 is stretched, so that the workpiece is clamped by movable clamp 15 and fixed clamp 3.

[0029] Please refer to the attached document for details. Figure 2 and attached Figure 4 To achieve longitudinal clamping, the device employs the following technical solution: The longitudinal clamping assembly includes a top plate 19 located inside the support 2. Several evenly distributed floating clamping units are arranged inside the top plate 19. Slider blocks 20 are fixedly connected to both the front and rear sides of the top plate 19. Two sliders 20 are slidably embedded in the grooves on the front and rear sides of the support 2. A screw b21, threadedly connected to the slider 20, is fitted inside the slider 20. The bottom end of the screw b21 extends to the bottom of the support 2 and is fixedly connected to a gear 22. The gear 22 is located on one side of the toothed plate 6 and meshes with the toothed plate 6. The connection between the screw b21 and the support 2 is also movably connected via a bearing. The movement of the toothed plate 6 drives the gear 22 to rotate, which in turn causes the screw b21 to rotate, causing the slider 20 to move downwards in the groove, thus moving the top plate 19 and the floating clamping units downwards, ultimately clamping the top of the workpiece.

[0030] Please refer to the attached document for details. Figure 4 In order to achieve a more stable clamping of the workpiece, the device adopts the following technical solution: The floating clamping unit includes a circular groove 1901 opened at the bottom of the top plate 19. A spring b23 is fixedly embedded in the circular groove 1901. A pressure head 24 is fixedly connected to the end of the spring b23. The pressure head 24 is slidably connected to the circular groove 1901. The pressure head 24 in the floating clamping unit can effectively clamp every area of ​​the workpiece. When the surface of the workpiece is uneven, the pressure head 24 can effectively clamp both the concave and convex positions.

[0031] Please refer to the attached document for details. Figure 6In order to facilitate the placement of workpieces of different thicknesses, the device adopts the following technical solution: both the movable clamp 15 and the fixed clamp 3 have stepped slots on their opposing sides; through the stepped slots, workpieces of different thicknesses can be directly placed into the corresponding thickness slots for initial fixation.

[0032] Please refer to the attached document for details. Figure 1 In order to facilitate the replacement of the support plate 25, the device adopts the following technical solution: a support plate 25 is provided on the surface of the frame 1 corresponding to the laser cutting head 4. The support plate 25 is detachably connected to the frame 1 by screws. The inside of the support plate 25 is set with a mesh structure. In actual operation, after the support plate 25 has been used for a period of time, a lot of metal residue will adhere to the surface, which is difficult to clean and can also easily scratch the workpiece placed on it. It can be quickly replaced by screws to ensure the safety of the workpiece placement.

[0033] Please refer to the attached document for details. Figure 2 In order to achieve the purpose of smooth movement of the connecting frame 9, the device adopts the following technical solution: two limiting rods 26 symmetrically distributed on both sides of the screw a8 are fixedly connected to the bottom of the frame 1. The two limiting rods 26 pass through the two connecting frames 9 respectively and are slidably connected to the connecting frames 9; the moving trajectory of the connecting frame 9 is limited by the limiting rods 26 to ensure that the slide 5 can stably drive the connecting frame 9 to move horizontally.

[0034] The usage process of this invention is as follows: When using this invention, the workpiece to be processed is placed on the frame 1, with one end of the workpiece abutting against the fixed clamp 3 and the other end facing the movable clamp 15. The workpiece processing area is located at the bottom of the laser cutting head 4. The motor 7 drives the screw a8 to rotate, thereby causing the slide 5 to move. When the slide 5 moves, it drives the base 14 to move. When the base 14 approaches the workpiece, the movable clamp 15 will first contact the workpiece. At this time, the base 14 continues to move, and the movable clamp 15 will move closer to the base 14. At the same time, the sliding column 16 moves inside the base 14, and the spring a18 is stretched, thereby making the workpiece clamped by the movable clamp 15 and the fixed clamp 3. At the same time, when the slide 5 moves, it also drives the toothed plate 6 to move through the adjustment unit, thereby rotating the moving gear 22, which makes the screw b Rotation 21 causes slider 20 to move downward in the groove, driving top plate 19 and floating clamping unit downward, ultimately clamping the top of the workpiece, achieving bidirectional clamping of the workpiece in both the horizontal and vertical directions. The pressure head 24 in the floating clamping unit can effectively clamp every area of ​​the workpiece. When the workpiece surface is uneven, the pressure head 24 can effectively clamp both concave and convex positions. When processing workpieces of different lengths, the position of the auxiliary rod 11 inside the main rod 10 can be adjusted to change the overall length of the adjustment unit. The length of the adjustment unit is locked by the pin 12 to adapt to the length of the workpiece to be processed, ensuring that the drive mechanism can synchronously drive the horizontal clamping component and the vertical clamping component. Specifically, when processing a longer workpiece, the adjustment unit can be shortened, and vice versa, for combined use.
