Description

Technical Field

[0001] This utility model belongs to the field of cutting equipment technology, and in particular to a high-precision metal laser cutting device. Background Technology

[0002] Laser cutting machines are cutting equipment designed using laser technology and CNC technology. Precision metals require corresponding cutting devices for laser cutting. Existing high-precision metal laser cutting devices use quick positioning components to quickly fix high-precision metals (specifically, high-precision stainless steel, titanium alloys, and aluminum alloys, etc., specifically for cutting regular plates) to improve processing efficiency, greatly increasing the processing efficiency. Although this increases the processing efficiency to a certain extent, the device generates scrap after cutting, which requires manual cleaning, making the cleaning operation time-consuming and labor-intensive.

[0003] A search revealed a Chinese patent document (authorization announcement number CN221363229U), which discloses a high-precision metal laser cutting device belonging to the field of laser cutting technology. The device includes a main module and a high-precision fixing module. The main module includes a processing table, with a laser cutting machine body fixedly connected to the top of the processing table. The high-precision fixing module includes two cross-shaped sliding grooves respectively extending through both sides of the top of the processing table. By opening a cylinder, the cross-shaped slider and two side-pressure components slide closer together. Hydraulic oil enters the hydraulic cylinder through a connecting pipe, pushing the piston rod to move and stretching the tension spring, thereby causing the friction pad at the bottom of the pressing block to contact the top of the material for pressing operation, thus achieving multi-point fixing. While this patent increases the processing efficiency of the device to some extent, the device generates scrap material after cutting, requiring manual cleaning, making the cleaning operation time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision metal laser cutting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-precision metal laser cutting device, comprising a processing table, a processing component for high-precision metal laser cutting mounted on the side of the processing table, two adjusting plates hinged to the top of the processing table, and a placement plate fixedly connected to the top of the adjusting plates, multiple auxiliary plates fixedly connected to the inner side of the processing table, and a lead screw rotatably connected between two auxiliary plates, a drive motor for providing power to the lead screw mounted on the side of the auxiliary plates, an auxiliary block threadedly connected to the outer circumference of the lead screw, and an auxiliary rod hinged to the side of the auxiliary block and hinged to the adjusting plate, a collection box slidably connected to the inner side of the processing table, and a guide rod fixedly connected to the inner side of the collection box, two symmetrical guide blocks slidably connected to the outer circumference of the guide rod, and a return spring installed between the side of the guide block and the inner wall of the collection box, a linkage rod hinged to the top of the guide rod, and a buffer plate hinged to the top of the linkage rod.

[0006] Specifically, the processing assembly includes a first linear motor fixedly connected to the side of the processing table and a mounting plate installed on the drive end of the first linear motor.

[0007] Specifically, the mounting plate has a fixed end of a second linear motor fixedly connected to its horizontal bottom end, and the drive end of the second linear motor is fixedly connected to a laser cutting assembly via a connecting block.

[0008] Specifically, a mounting box is fixedly connected to the vertical side of the mounting plate, and a sliding rod is fixedly connected to the inner side of the mounting box.

[0009] Specifically, the outer periphery of the slide bar has two sliders slidably connected, and the top of the sliders is hinged to a movable rod.

[0010] Specifically, the top of the mounting box is equipped with the fixed end of an electric push rod, and the driving end of the electric push rod passes through the mounting box and is fixedly connected to a support column. The bottom end of the support column is hinged to two movable rods.

[0011] Specifically, a connecting rod is fixedly connected to the side of the slider, and a fixing plate is fixedly connected to one end of the connecting rod.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0013] This high-precision metal laser cutting device, thanks to the design of its drive motor and processing components, adjusts an auxiliary block around the lead screw by starting the drive motor. This adjustment causes an adjustment plate at one end of the auxiliary rod to tilt, allowing scrap materials to slide into the collection box. A reset spring installed inside the collection box provides cushioning (reducing the distance between the cushioning plate and the adjustment plate, thus reducing processing noise and indirectly extending the collection box's lifespan). Compared to existing cleaning methods, this device is more time- and labor-saving. Furthermore, the design of the processing components facilitates adjustment of the laser cutting components and allows for workpiece fixation, greatly increasing the device's practicality.

[0014] This high-precision metal laser cutting device can automatically clean up the scraps generated during processing, making the cleaning operation more time-saving and labor-saving. Attached Figure Description

[0023] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0024] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0025] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs. Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail; however, where appropriate, such techniques, methods, and equipment should be considered part of the specification. The proportions of the components in the accompanying drawings are for reference only and can be adjusted to a certain extent according to the actual use.

[0026] Examples, such as Figures 1 to 5As shown, a processing component 3 for high-precision metal laser cutting is installed on the side of the processing table 1. Two adjusting plates 4 are hinged to the top of the processing table 1, and a placement plate 5 is fixedly connected to the top of each adjusting plate 4. Multiple auxiliary plates 11 are fixedly connected to the inner side of the processing table 1, and a lead screw 12 is rotatably connected between two auxiliary plates 11. The placement plate 5 is designed to prevent workpieces from being processed. Having two placement plates 5 allows the device to continue processing even when cleaning up scrap. A drive motor 14 that provides power to the lead screw 12 is installed on the side of the auxiliary plate 11. An auxiliary block 13 is threadedly connected to the outer circumference of the lead screw 12, and the side of the auxiliary block 13 is hinged to an auxiliary plate 4. A collection box 2 is slidably connected to the inner side of the processing table 1 via rod 15. The collection box 2 is used for collecting scrap materials. Rubber pads are adhered to the inner wall of the collection box 2 and the buffer plate 6. The rubber pads can make the device quieter and effectively prevent scrap materials from bumping into the collection box 2. A guide rod 7 is fixedly connected to the inner side of the collection box 2. Two symmetrical guide blocks 8 are slidably connected to the outer periphery of the guide rod 7. A return spring 9 is installed between the side of the guide block 8 and the inner wall of the collection box 2. The design of the return spring 9 can reduce the gap 9 between the buffer plate 6 and the adjustment plate 4. As the weight increases, the buffer plate 6 slowly descends. The top of the guide rod 7 is hinged to a linkage rod 10, and the top of the linkage rod 10 is hinged to the buffer plate 6.

[0027] The processing component 3 includes a first linear motor 31 fixedly connected to the side of the processing table 1 and a mounting plate 32 mounted on the drive end of the first linear motor 31. The bottom horizontal end of the mounting plate 32 is fixedly connected to the fixed end of the second linear motor 33. The design of the first linear motor 31 and the second linear motor 33 can assist the laser cutting component 34 in position adjustment. The drive end of the second linear motor 33 is fixedly connected to the laser cutting component 34 through a connecting block. The laser cutting component 34 is a mature existing technology and specifically includes the following structure: laser, cutting head, laser transmission system and auxiliary gas system.

[0028] Mounting plate 32 is fixedly connected to mounting box 35 on its vertical side. Mounting box 35 is fixedly connected to sliding rod 351 on its inner side. Two sliders 352 are slidably connected to the outer periphery of sliding rod 351. The top of slider 352 is hinged to movable rod 353. Activating electric push rod 36 can drive two fixed plates 38 to move towards each other, thereby achieving the fixation of the workpiece. The top of mounting box 35 is equipped with the fixed end of electric push rod 36. The driving end of electric push rod 36 passes through mounting box 35 and is fixedly connected to support column 354. The bottom end of support column 354 is hinged to two movable rods 353. The side of slider 352 is fixedly connected to connecting rod 37. One end of connecting rod 37 is fixedly connected to fixed plate 38. The side of fixed plate 38 is glued with soft anti-slip pad, which can not only increase friction but also protect the workpiece.

[0029] The first linear motor 31, the second linear motor 33, the electric push rod 36, and the drive motor 14 are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. They are all controlled by remote control switches. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail. The scale of the attached drawings is for reference only and can be adjusted to a certain extent according to the actual use.

[0030] Working principle

[0031] In this high-precision metal laser cutting device, the high-precision metal workpiece to be cut is placed on the placement plate 5. The electric push rod 36 is activated to drive the movable rod 353 at the bottom of the support column 354 to move in conjunction. The adjustment of the movable rod 353 causes the side connecting rod 37 of the slider 352 to move in opposite directions, so that the two fixed plates 38 fix the workpiece. The laser cutting component 34 performs the cutting operation. During the cutting process, the first linear motor 31 and the second linear motor 33 are activated to assist in the operation as needed. When the processing is completed, the finished product is unloaded. As needed, the drive motor 14 at one end is activated to drive the lead screw 12 to rotate. The rotation of the lead screw 12 can cause the adjusting plate 4 to tilt to a certain angle, so that the scraps on the surface of the placement plate 5 slide into the collection box 2 for centralized processing.
