Description

Technical Field

[0001] This application belongs to the field of laser cutting technology, and more specifically, relates to an auxiliary device for laser cutting of aluminum alloy sheets. Background Technology

[0002] Aluminum alloy sheets, due to their outstanding advantages such as light weight, high strength, corrosion resistance, and good machinability, have been widely used in numerous industries including aerospace, automotive manufacturing, electronic equipment, and architectural decoration. Laser cutting technology, as an advanced processing method, has become an indispensable tool in the processing of aluminum alloy sheets (hereinafter referred to as sheets) due to its significant characteristics such as high cutting precision, high speed, small heat-affected zone, and good cut surface quality. Through laser cutting, sheets can be precisely cut into parts of various complex shapes, meeting the stringent requirements of different industries for product precision and quality, and greatly improving production efficiency and product quality.

[0003] When laser-cutting sheet metal, it first needs to be placed on the laser cutting machine. Since the laser cuts through the sheet metal, the machine typically uses spaced toothed plates to support the aluminum alloy sheet. However, sheet metal usually has a certain size and weight, making it extremely inconvenient to move it manually or with external tools. Furthermore, during movement, the bottom of the sheet metal can easily come into contact with and rub against the toothed plates, affecting the quality of the final product and its market competitiveness. Utility Model Content

[0004] Based on the above-mentioned technical problems, this application provides an auxiliary device for laser cutting of aluminum alloy sheets to solve the technical problems in the prior art, such as the inconvenience of manual handling or moving of sheets using external tools, and the ease with which the bottom of the sheet can come into contact with and rub against the toothed plate, affecting product quality.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: An auxiliary device for laser cutting of aluminum alloy sheets is provided, comprising: a machine tool, a laser cutting blade disposed above the machine tool, and a moving component for driving the laser cutting blade to move. Multiple toothed plates are fixedly disposed at the top of the machine tool, and these toothed plates are spaced apart along the length direction of the machine tool. Inside the machine tool, multiple shafts are spaced apart and rotatably disposed along the width direction of the machine tool. The axial direction of the multiple shafts is perpendicular to the length direction of the toothed plates. On each shaft, multiple support components are fixedly disposed at intervals along the axial direction of the shaft. The free end of each support component passes through the gap between two adjacent toothed plates, extends upwards towards the machine tool, and is slidably connected to the bottom surface of the sheet material. A power unit for driving the multiple shafts to rotate is provided on one side of the machine tool.

[0006] Furthermore, the support assembly includes a support rod, one end of which is fixedly connected to the shaft, and the other end of which is provided with a universal ball bearing.

[0007] Furthermore, the power unit includes multiple sprockets, which are respectively fixedly sleeved on one end of multiple shafts. A chain is wound around the outside of the multiple sprockets. One end of one of the shafts extends through the side wall of the machine tool to the outside of the machine tool and is provided with a rocker arm for driving the shaft to rotate.

[0008] Furthermore, the machine tool is rotatably equipped with multiple tensioning wheels, which are respectively rotatably arranged between two adjacent shafts and mesh with the chain.

[0009] Furthermore, a sleeve is fixedly provided on one side of the machine tool, and the sleeve is coaxially sleeved on the outside of the shaft. A first groove is provided at the end of the sleeve away from the machine tool. The rocker arm includes a polygonal rod fixed to one end of the shaft and a slide rod slidably sleeved on the outside of the polygonal rod. A first spring is sleeved on the outside of the polygonal rod for pushing the slide rod to move closer to the sleeve. When supporting the aluminum alloy plate, one end of the slide rod is engaged in the first groove.

[0010] Furthermore, inside the machine tool, multiple fixed plates are fixedly arranged at intervals along the length of the machine tool. One end of each of the multiple shafts is rotatably connected to the side wall of one side of the machine tool, and the other end of each shaft passes through the multiple fixed plates and is rotatably connected to the side wall of the other side of the machine tool.

[0011] Furthermore, each of the fixed plates is fixed with a baffle on one side of the support assembly. When the laser cutting blade is in operation, the free end of the support assembly rotates to the bottom of the baffle.

[0012] Furthermore, the sleeve is provided with a second slot at the end away from the machine tool. When the free end of the support assembly rotates to the bottom of the baffle, one end of the slide rod is engaged in the first slot.

[0013] Compared with the prior art, the beneficial effects of the laser cutting auxiliary device for aluminum alloy plates provided in this application are: By setting a rotatable shaft and support assembly, the universal ball bearings of the support assembly allow the sheet metal to slide easily when it is placed and moved, solving the problem of inconvenient movement of the sheet metal on the machine tool, avoiding direct friction between the sheet metal and the toothed plate, reducing the risk of damage to the sheet metal surface due to friction, and improving product quality.

[0014] The baffles installed on the fixed plate prevent the support components from interfering with the cutting operation during laser cutting, and also prevent sparks generated during cutting from damaging the support components.

[0015] By using a sleeve, a first retaining groove, a rocker arm, and a first spring, the shaft can be quickly fixed and released, making operation convenient and improving work efficiency while ensuring the stability of the support assembly during operation. The second retaining groove further facilitates the positioning of the shaft, ensuring that the support assembly will not rotate unexpectedly during laser cutting, thus guaranteeing the stability and safety of the cutting process.

[0024] Please refer to the following: Figures 1 to 5 As shown, the following describes a laser cutting auxiliary device for aluminum alloy sheets provided in an embodiment of this application. The laser cutting auxiliary device for aluminum alloy sheets of this utility model includes a machine tool 1, a laser cutting blade 2, and a moving component 3. The machine tool 1 is used to support the sheet material (aluminum alloy sheet) to be cut. Specifically, multiple toothed plates 11 are fixedly provided at the top of the machine tool 1, and the multiple toothed plates 11 are arranged at intervals along the length direction of the machine tool 1 to support the sheet material. The laser cutting blade 2 and the moving component 3 are both prior art. The laser cutting blade 2 is used to cut the sheet material, and the moving component 3 is used to drive the laser cutting blade 2 to move along the length direction, width direction, and height direction (X-axis, Y-axis, Z-axis) of the machine tool 1, which will not be described in detail here.

[0025] The machine tool 1 has multiple rotating shafts 4 (three in this embodiment) arranged internally. These shafts 4 are spaced apart along the width of the machine tool 1, and their axial directions are perpendicular to the length of the toothed plate 11. Each shaft 4 is also fixed with multiple support components 5 to support the plate material and facilitate sliding of the plate material on the support components 5, preventing the toothed plate 11 from scratching the plate material. The support components 5 are spaced apart along the axial direction of the shafts 4, and the free end of each support component 5 passes through the gap between two adjacent toothed plates 11, extending upwards towards the machine tool 1 (e.g., ...). Figure 3 As shown, at this time, the horizontal height of the free end of the support component 5 is higher than the horizontal height of the top of the toothed plate 11. A power unit 6 for driving multiple shafts 4 to rotate is provided on one side of the machine tool 1.

[0026] In practice, before laser cutting, the aluminum alloy sheet is placed on machine tool 1. During placement, multiple support components 5 contact the bottom of the sheet, allowing it to slide on the top of the support components 5. This facilitates sheet movement and prevents the toothed plates 11 from scratching the sheet. Once in position, multiple shafts 4 are driven to rotate, which in turn rotates the support components 5, moving them away from the sheet. As the support components 5 cease to support the sheet, the bottom surface is supported by the toothed plates 11, allowing for cutting. By using rotatable shafts 4 and support components 5, the problem of inconvenient sheet movement on machine tool 1 is solved, direct friction between the sheet and the toothed plates 11 is avoided, damage to the sheet is reduced, and product quality and production efficiency are improved.

[0027] In this embodiment, the support assembly 5 includes a support rod 51 and a universal ball bearing 52. One end of the support rod 51 is fixedly connected to the shaft 4, and the universal ball bearing 52 is rotatably disposed at the other end of the support rod 51. During implementation, the universal ball bearing 52 contacts the bottom of the plate. During the movement of the plate, the universal ball bearing 52 can roll freely, allowing the plate to slide easily on the machine tool 1. This makes the movement of the plate smoother and more flexible, further reducing the risk of damage to the plate surface due to friction.

[0028] Please see Figure 4 As shown, in this embodiment, the power unit 6 includes multiple sprockets 61, which are respectively fixedly sleeved on one end of multiple shafts 4. A chain 62 is wound around the outer side of the multiple sprockets 61. One end of one shaft 4 extends outward through the side wall of the machine tool 1 and is equipped with a rocker arm 7 for driving the shaft 4 to rotate. In practice, rotating the rocker arm 7 drives one of the shafts 4 to rotate. At this time, the sprocket 61 on the shaft 4 drives the other sprockets 61 to rotate through the chain 62, thereby making the multiple shafts 4 rotate synchronously and realizing the overall rotation of the support assembly 5. That is, by adopting the transmission method of sprockets 61 and chain 62, the synchronous rotation of multiple shafts 4 can be achieved, so that the support assembly 5 can operate simultaneously, making the operation simpler and more efficient.

[0029] Preferably, multiple tensioning wheels 63 are rotatably arranged inside the machine tool 1. The multiple tensioning wheels 63 are respectively rotatably arranged between two adjacent shafts 4 and mesh with the chain 62. The tensioning wheels 63 ensure the stability and reliability of the chain 62 transmission, avoid transmission failures caused by the chain 62 loosening or falling off, and improve the operational stability of the entire device.

[0030] In this embodiment, multiple fixing plates 12 are fixedly installed at intervals along the length of the machine tool 1 inside the machine tool 1. One end of multiple shafts 4 is rotatably connected to one side wall of the machine tool 1, and the other end of the shafts 4 passes through the multiple fixing plates 12 and is rotatably connected to the other side wall of the machine tool 1. The multiple fixing plates 12 provide support and positioning for the shafts 4, making it less prone to deformation or shaking during rotation and ensuring the stability of the shafts 4 during rotation.

[0031] Preferably, each fixed plate 12 is fixed with a baffle 121 on one side of the support assembly 5. When the laser cutting blade 2 is in working condition, the free end of the support assembly 5 rotates to the bottom of the baffle 121. By setting the baffle 121, the interference of the support assembly 5 with the cutting operation during laser cutting is avoided, and the sparks generated during cutting are prevented from damaging the support assembly 5.

[0032] Please see Figure 5 As shown, in this embodiment, a sleeve 8 is fixedly provided on one side of the machine tool 1. The sleeve 8 is coaxially sleeved on the outside of the shaft 4. The end of the sleeve 8 away from the machine tool 1 is provided with a first slot 81. The rocker arm 7 includes a polygonal rod 71 fixedly provided on one end of the shaft 4 and a sliding rod 72 slidably sleeved on the outside of the polygonal rod 71. (It should be noted that the inner wall of the sliding rod 72 is adapted to the outer wall of the polygonal rod 71. Therefore, the sliding rod 72 and the polygonal rod 71 can only slide and cannot rotate relative to each other. However, during the rotation of the sliding rod 72, the polygonal rod 71 can be driven to rotate synchronously, thereby driving the shaft 4 fixedly connected to the polygonal rod 71 to rotate synchronously.) A first spring 73 is sleeved on the outside of the polygonal rod 71 to push the sliding rod 72 to move closer to the sleeve 8. Specifically, a retaining ring 74 is fixedly provided on the end of the polygonal rod 71 away from the sleeve 8. The two ends of the first spring 73 abut against the retaining ring 74 and the sliding rod 72, respectively. When supporting the aluminum alloy plate, one end of the sliding rod 72 is engaged in the first slot 81.

[0033] During implementation, the slide bar 72 is engaged in the first slot 81 by the push of the first spring 73. This, along with the limitation provided by the first slot 81, prevents the slide bar 72, the polygonal rod 71, and the shaft 4 from rotating, thus providing stable support for the sheet metal. Before cutting the sheet metal, the operator pulls the slide bar 72, moving it away from the sleeve 8 until it disengages from the first slot 81. At this point, the first spring 73 is compressed, and then the slide bar 72 is rotated, causing the polygonal rod 71 and the shaft 4 to rotate synchronously, bringing the support assembly 5 to a position below the baffle 121. Through the cooperation of the sleeve 8, the first slot 81, the rocker arm 7, and the first spring 73, the shaft 4 can be quickly fixed and released, making operation convenient, improving work efficiency, and ensuring the stability of the support assembly 5 during operation.

[0034] Preferably, the end of the sleeve 8 furthest from the machine tool 1 is also provided with a second slot 82. When the free end of the support assembly 5 rotates to below the baffle 121, one end of the slide rod 72 is engaged in the second slot 82. In practice, when the free end of the support assembly 5 rotates to below the baffle 121, the elastic reset of the first spring 73 pushes the slide rod 72 of the rocker arm 7 towards the sleeve 8, so that one end of the slide rod 72 is engaged in the second slot 82. At this time, the shaft 4 is fixed and does not affect laser cutting. The setting of the second slot 82 further facilitates the positioning of the shaft 4, ensuring that the support assembly 5 will not rotate accidentally during laser cutting, thus ensuring the stability and safety of the cutting process.

[0035] In a specific implementation of this utility model, before laser cutting, the aluminum alloy sheet is placed on the machine tool 1. At this time, the support assembly 5 (support rod 51 and universal ball bearing 52) contacts the bottom of the sheet. Since the universal ball bearing 52 can roll freely, the sheet can easily slide on the top of multiple support assemblies 5, facilitating the movement of the sheet and preventing the toothed plates 11 from scratching it. After the sheet is moved into place, the operator pulls the slide rod 72 of the rocker arm 7, causing the slide rod 72 to move away from the sleeve 8 and disengage from the first slot 81. The first spring 73 is compressed. Then, the slide rod 72 is rotated, causing the polygonal rod 71 and the shaft 4 to rotate synchronously, thereby causing the support assembly 5 to rotate. When the free end of the support assembly 5 rotates to below the baffle 121, the rocker arm 7 is released, the first spring 73 elastically returns to its original position, and the slide rod 72 is pushed towards the sleeve 8, so that one end of the slide rod 72 is engaged in the second slot 82. At this time, the shaft 4 is fixed, and the bottom surface of the sheet is supported by multiple toothed plates 11, allowing the sheet to be cut. It should be noted that in this embodiment, the extension direction of the free end of the slide rod 72 is opposite to the extension direction of the free end of the support component 5. That is, the free end of the slide rod 72 can support the free end of the support component 5 to extend outward along the radial sides of the shaft 4 respectively. In other words, when the support component 5 is preparing to support the plate, the free end of the slide rod 72 faces downward of the lathe to avoid affecting the loading.

[0036] It is understood that the parts in the above embodiments can be freely combined or deleted to form different combined embodiments. The specific contents of each combined embodiment will not be repeated here. After this description, it can be considered that the present utility model specification has recorded each combined embodiment and can support different combined embodiments.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
