Description

Technical Field

[0001] This invention relates to the field of laser processing, and in particular to a CNC laser integrated production and processing device adapted to multi-element metal sheet. Background Technology

[0002] The CNC laser integrated production and processing equipment for metal sheets is a device for laser processing the surface of metal sheets. It uses a focused laser beam to instantly melt or vaporize the material to complete the cutting of the metal sheet.

[0003] However, existing production and processing equipment often uses fixed laser heads or allows only minor angle adjustments within a small range, making it difficult to meet the multi-angle processing needs of irregularly shaped materials such as curved surfaces, bevels, and stepped shapes. If the processing angle needs to be changed, the laser head often needs to be manually disassembled or the workpiece repositioned, which is not only time-consuming and labor-intensive but also cannot guarantee the consistency of accuracy in continuous processing. In existing equipment, the fixture is usually independently mounted on the worktable or frame and is not rigidly connected to the laser head motion system. When the laser head needs to be rotated or its position adjusted for processing, the fixture cannot move synchronously, causing the relative coordinates between the workpiece clamping point and the laser head emission point to change. Operators must repeatedly perform secondary tool setting and recalibrate the fixture position, which seriously affects the efficiency and accuracy of multi-process and multi-angle continuous processing. In the case of a rotating laser structure, the equipment lacks an effective auxiliary support structure, which can easily cause the center of gravity to shift, the machine body to shake, or even overturn during the laser head rotation process. In the horizontal processing state, the suspended connecting parts often vibrate due to lack of support, reducing processing quality and accelerating equipment wear. Summary of the Invention

[0004] The main objective of this invention is to provide a CNC laser integrated production and processing device for multi-element metal sheets, which can effectively solve the problems mentioned in the background art, such as the difficulty in meeting the multi-angle processing needs of irregularly shaped sheets with curved surfaces, beveled edges, and stepped shapes, and the lack of effective auxiliary support structures in the device.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A CNC laser integrated production and processing device for multi-element metal sheets includes a base plate. A worktable is fixedly installed on the upper end of the base plate. A base is fixedly installed behind the worktable on the upper end of the base plate. A through-rotating shaft is movably installed at the center of the base. Side plates are fixedly installed at both ends of the shaft. A first guide rod is fixedly installed at the front end of each of the two side plates. A connecting plate is fixedly installed at the front end of the first guide rod. A first motor is fixedly installed on the outer side of the connecting plate. A gear is fixedly installed at the end of the shaft of the first motor. A first sliding frame is slidably installed on the outer side of each of the two first guide rods. A second guide rod is fixedly installed between the two first sliding frames. A second sliding frame is slidably installed on the outer side of the second guide rod. A laser is fixedly installed at the rear end of the second sliding frame. A clamping structure for holding metal sheets is fixedly installed at the lower end of each of the two first sliding frames. Support frames are fixedly installed on both sides of the worktable on the upper end of the base plate. An arc-shaped frame is fixedly installed on the upper end of the support frame. A toothed rack is cut into the bottom surface of the arc-shaped frame.

[0007] As a further embodiment of the present invention, a first support rod and a second support rod are fixedly installed between the two first guide rods, the first support rod is located behind the second support rod, and the first support rod, the second support rod and the first guide rod are arranged in a square.

[0008] As a further embodiment of the present invention, a second motor is fixedly installed on one side of the first sliding frame, and the rotating shaft of the second motor is fixedly connected to the rotating wheel inside the first sliding frame. A third motor is fixedly installed at the front end of the second sliding frame, and the rotating shaft of the third motor is fixedly connected to the rotating wheel of the second sliding frame.

[0009] As a further embodiment of the present invention, the clamping structure includes a fixed plate, a screw, a clamping plate, an adjusting plate, a guide rod, and a handle. The fixed plate is fixedly installed at the lower end of the first sliding frame, the screw is threadedly installed at the center of the fixed plate, the clamping plate is movably installed at one end of the screw, the adjusting plate is movably installed at the other end of the screw, the guide rod is fixedly installed between the adjusting plate and the clamping plate, and the handle is movably installed on one side of the adjusting plate.

[0010] As a further embodiment of the present invention, the shaft of the handle passes through the adjusting plate and is fixedly connected to the screw, and the guide rod is located below the screw and movably passes through the fixing plate.

[0011] As a further embodiment of the present invention, the clamping plate is located above the workbench, and the clamping plates on both sides are arranged symmetrically.

[0012] As a further embodiment of the present invention, a transmitter head is fixedly installed at the lower end of the laser, with the transmitter head facing the worktable.

[0013] As a further embodiment of the present invention, the arc-shaped frame is located on both sides of the two connecting plates, and the gear is meshed with the rack.

[0014] As a further embodiment of the present invention, bushings are fixedly installed on both sides of the bottom of the support frame, and the bushings are movably connected to the sides of the two side plates through a rotating shaft.

[0015] As a further embodiment of the present invention, pads are attached to both sides of the upper front end of the base plate, and the lower end of the connecting plate is placed on top of the pads.

[0016] Compared with the prior art, the present invention has the following beneficial effects: By setting gears to mesh with racks on the arc frame, and cooperating with the first motor drive, the first guide rod, the first support rod, the second support rod and the laser as a whole can achieve a wide range of angle rotation from 0° to 90° along the arc trajectory. This breaks through the limitation of traditional laser processing devices that can only operate on a plane. It can flexibly adapt to the laser cutting, engraving or welding needs of various irregular metal plates such as curved surfaces, inclined edges, and stepped shapes, and greatly improves the processing adaptability and application breadth of the device.

[0017] The fixture structure adopts a combination design of screw, clamping plate, guide rod and handle. By rotating the handle, the clamping plates on both sides can be driven to move inward or outward simultaneously, realizing the rapid clamping and release of metal plates. The guide rod effectively prevents the clamping plates from shifting and ensures clamping stability. Moreover, the fixture moves synchronously with the first sliding frame and can maintain the relative position with the laser head without additional adjustment, which simplifies the clamping process and improves production efficiency.

[0018] The fixture structure is fixedly installed at the lower end of the first sliding frame, while the laser is mounted on the second guide rod between the two first sliding frames via the second sliding frame, forming a rigid connection between the fixture and the laser head on a common base. When the first motor drives the gear to mesh and roll along the rack of the arc-shaped frame, causing the first guide rod, the second guide rod, and the laser to rotate from 0° to 90°, the fixture structures on both sides rotate synchronously with the first sliding frame, always maintaining a constant relative position with the laser emitter head. This solves the problem of traditional devices requiring repeated recalibration of the fixture position after changing the processing angle. Regardless of whether the laser head is in a horizontal, tilted, or vertical position, the metal sheet is always clamped at the same reference point corresponding to the preset coordinates of the laser head, eliminating the need for secondary tool setting or clamping adjustments. This significantly improves the accuracy and efficiency of multi-angle, multi-process continuous processing, and is especially suitable for complex process scenarios such as curved surface flanging and bevel cutting.

[0019] The support frame is movably connected to the side plate via a bushing. Together with the pad at the front end of the base plate, it provides stable support for the connecting plate when the laser is in a horizontal position, preventing it from swaying in mid-air. During the flipping process, the rotating shaft rotates around the base, ensuring a smooth transition of the overall center of gravity. This not only ensures the structural rigidity during processing but also reduces the risk of equipment tipping over, enhancing operational safety and equipment lifespan. Attached Figure Description

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] like Figures 1-7 As shown, a CNC laser integrated production and processing device adapted to multi-element metal sheet is described. (See reference) Figures 1-7The system includes a base plate 1, a worktable 2 fixedly mounted on the upper end of the base plate 1, a base 3 fixedly mounted behind the worktable 2 on the upper end of the base plate 1, a through-type rotating shaft 4 movably mounted in the center of the base 3, side plates 5 fixedly mounted on both ends of the rotating shaft 4, first guide rods 6 fixedly mounted on the front ends of the two side plates 5, connecting plates 9 fixedly mounted on the front ends of the first guide rods 6, a first motor 10 fixedly mounted on the outer side of the connecting plates 9, and a gear 11 fixedly mounted on the shaft end of the first motor 10. The outer sides of the two first guide rods 6 are also equipped with sliding... A first sliding frame 12 is mounted on the workbench 2. A second guide rod 14 is fixedly mounted between the two first sliding frames 12. A second sliding frame 15 is slidably mounted on the outside of the second guide rod 14. A laser 17 is fixedly mounted on the rear end of the second sliding frame 15. A clamping structure 19 for holding metal plates is fixedly mounted on the lower end of each of the two first sliding frames 12. A support frame 26 is fixedly mounted on both sides of the upper end of the base plate 1 on the workbench 2. An arc frame 28 is fixedly mounted on the upper end of the support frame 26. A toothed rack 29 is cut and formed on the bottom surface of the arc frame 28.

[0030] See Figure 1 and Figure 2 A first support rod 7 and a second support rod 8 are fixedly installed between the two first guide rods 6. The first support rod 7 is located behind the second support rod 8, and the first support rod 7, the second support rod 8 and the first guide rod 6 are arranged in a square.

[0031] See Figure 1 and Figure 2 A second motor 13 is fixedly installed on one side of the first sliding frame 12. The shaft of the second motor 13 is fixedly connected to the wheel inside the first sliding frame 12. A third motor 16 is fixedly installed at the front end of the second sliding frame 15. The shaft of the third motor 16 is fixedly connected to the wheel of the second sliding frame 15.

[0032] Specifically, the second motor 13 and the third motor 16 are connected to an external power source for operation. When the second motor 13 is running, it drives the wheel inside the first sliding frame 12 to rotate, causing the first sliding frame 12 to slide outside the first guide rod 6, thereby changing the front and rear position of the laser 17. When the third motor 16 is running, it drives the wheel inside the second sliding frame 15 to rotate, causing the second sliding frame 15 to slide outside the second guide rod 14, thereby changing the left and right position of the laser 17.

[0033] See Figure 4 The clamping structure 19 includes a fixed plate 20, a screw 21, a clamping plate 22, an adjusting plate 23, a guide rod 24, and a handle 25. The fixed plate 20 is fixedly installed at the lower end of the first sliding frame 12. The screw 21 is threadedly installed at the center of the fixed plate 20. The clamping plate 22 is movably installed at one end of the screw 21. The adjusting plate 23 is movably installed at the other end of the screw 21. The guide rod 24 is fixedly installed between the adjusting plate 23 and the clamping plate 22. The handle 25 is movably installed on one side of the adjusting plate 23.

[0034] See Figure 4 The shaft of handle 25 passes through adjusting plate 23 and is fixedly connected to screw 21. Guide rod 24 is located below screw 21 and moves through fixing plate 20.

[0035] See Figure 2 and Figure 4 The clamping plate 22 is located above the workbench 2, and the clamping plates 22 on both sides are arranged symmetrically.

[0036] Specifically, a metal sheet to be laser-processed is placed on top of the workbench 2. The screw 21 is rotated by the handle 25. The screw 21 is screwed in and out left and right through the threaded connection with the fixing plate 20, thereby driving the clamping plate 22 to move left and right. By merging and separating the two clamping plates 22, the metal sheet on top of the workbench 2 is clamped and fixed.

[0037] See Figure 3 A transmitter head 18 is fixedly installed at the lower end of the laser 17, and the transmitter head 18 faces the worktable 2.

[0038] Specifically, when the laser 17 is powered on, it emits a laser beam through the transmitter 18 to the metal plate above the worktable 2 after the laser 17 is turned on and running, thereby realizing the laser processing of the metal plate.

[0039] See Figures 5-7 The arc-shaped frame 28 is located on both sides of the two connecting plates 9, and the gear 11 is meshed with the rack 29.

[0040] See Figure 6 and Figure 7 Both sides of the bottom of the support frame 26 are fixedly installed with bushings 27, and the bushings 27 are movably connected to the sides of the two side plates 5 through a rotating shaft.

[0041] Specifically, the first motor 10 is connected to an external power source for operation. When the first motor 10 is running, it drives the gear 11 to rotate. The rotation of the gear 11 is connected to the rack 29 through meshing, and moves around the rack 29, thereby driving the first support rod 7, the second support rod 8 and the first guide rod 6 to rotate as a whole. At the same time, the rotating shaft 4 rotates around the base 3 and the side plate 5 rotates around the bushing 27, adjusting the overall angle of the laser 17 from 0° to 90°, and cooperating with the multi-element metal plate for laser processing.

[0042] See Figure 7 The base plate 1 has pads 30 pasted on both sides of the upper front end, and the lower end of the connecting plate 9 is placed on top of the pads 30.

[0043] Specifically, when the first support rod 7, the second support rod 8, and the first guide rod 6 are in a parallel state, the connecting plate 9 is placed above the pad 30 for support and positioning.

[0044] 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 illustrative of the principles of the invention.
