Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and more specifically, to a sheet metal laser cutting device. Background Technology

[0002] Sheet metal laser cutting is a technology that uses a high-power-density laser beam to irradiate the material being cut, rapidly heating the material to its vaporization temperature, thereby evaporating it to form a hole. Finally, the movement of the laser beam forms a kerf, achieving precise cutting of the material.

[0003] Currently, when using laser cutting equipment to cut sheet metal products, in order to prevent the sheet metal products from shifting and affecting the cutting accuracy, the sheet metal products need to be fixed on the laser cutting equipment. However, most existing laser cutting equipment requires manual fixing of the sheet metal products, and after cutting, the fixing mechanism still needs to be manually opened to remove the products, resulting in low work efficiency when laser cutting large batches of sheet metal products. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a sheet metal laser cutting device, which aims to solve the problem that most existing laser cutting devices require manual fixing of sheet metal products, and after cutting, manual opening of the fixing mechanism is still required to remove the product, resulting in low work efficiency when laser cutting large batches of sheet metal products.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A sheet metal laser cutting device includes a feeding slide rail module and a three-axis slide rail module. The feeding slide rail module is disposed inside the three-axis slide rail module. A limiting plate is fixedly connected to one end of the feeding slide rail module and the three-axis slide rail module. A laser head is disposed on the three-axis slide rail module. A feeding tray is disposed on the feeding slide rail module, and the feeding tray corresponds to the limiting plate and the laser head. Two rotating rods are rotatably connected to the bottom end of the feeding tray. A pressure frame is fixedly connected to both ends of the two rotating rods, and the two pressure frames are located on symmetrical sides of the feeding tray. A pressure block assembly is fixedly connected to each of the two pressure frames, and the two pressure block assemblies correspond to the feeding tray. A rotating mechanism is disposed between the two rotating rods and the feeding tray. The rotating mechanism is used to control the rotation of the two rotating rods, so that the two pressure block assemblies on the two pressure frames rotate to press and fix the sheet metal product in the feeding tray.

[0008] In a preferred embodiment of this utility model, the rotating mechanism includes a fixed rod, a shaped rack rod, a spring, and two gears. The fixed rod is fixedly connected to the bottom end of the feeding tray. The shaped rack rod is slidably connected to the fixed rod, and one end of the shaped rack rod corresponds to the limiting plate. The spring is sleeved on the circumferential surface of the fixed rod and corresponds to the shaped rack rod. The two gears are respectively fixedly connected to the circumferential surfaces of the two rotating rods, and the two gears mesh with the shaped rack rod in an alternating manner.

[0009] As a preferred embodiment of this utility model, a rubber buffer block is fixedly connected to one end of the limiting plate near the feeding tray, and the rubber buffer block corresponds to the irregularly shaped rack rod.

[0010] As a preferred embodiment of this utility model, a cylinder module is fixedly connected to the bottom of the feeding tray, and a lifting plate assembly is fixedly connected to the output end of the cylinder module, with the lifting plate assembly located inside the feeding tray.

[0011] As a preferred embodiment of this utility model, a sensor is fixedly connected to one side wall of the feeding tray. Beneficial effects

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] (1) In this solution, the sheet metal product is placed in the feeding tray. After the feeding tray moves to the cutting position, the rotating mechanism contacts the limiting plate, so that the two pressure frames and two pressure block assemblies automatically rotate to press and fix the sheet metal product, ensuring the stability of the sheet metal product during laser cutting. After the sheet metal product is cut, the rotating mechanism moves away from the limiting plate, so that the two pressure frames and two pressure block assemblies automatically open, canceling the fixation of the sheet metal product. This device does not require manual positioning of the product. The sheet metal product can be automatically fixed and opened when it moves to the required position during laser cutting, saving product positioning time and thus improving work efficiency.

[0022] Please see Figure 1-3A sheet metal laser cutting device includes a feeding slide rail module 1 and a three-axis slide rail module 2. The feeding slide rail module 1 is located inside the three-axis slide rail module 2. A limiting plate 3 is fixedly connected to one end of the feeding slide rail module 1 and the three-axis slide rail module 2. A laser head 13 is provided on the three-axis slide rail module 2. A feeding tray 4 is provided on the feeding slide rail module 1, and the feeding tray 4 corresponds to the limiting plate 3 and the laser head 13. Two rotating rods 5 are rotatably connected to the bottom end of the feeding tray 4. A pressure frame 6 is fixedly connected to both ends of the two rotating rods 5, and the two pressure frames 6 are located on symmetrical sides of the feeding tray 4. A pressure block assembly 7 is fixedly connected to each of the two pressure frames 6, and the two pressure block assemblies 7 correspond to the feeding tray 4. A rotating mechanism is provided between the two rotating rods 5 and the feeding tray 4. The rotating mechanism is used to control the rotation of the two rotating rods 5, so that the two pressure block assemblies 7 on the two pressure frames 6 rotate to press and fix the sheet metal product in the feeding tray 4.

[0023] In this embodiment, when laser cutting sheet metal products, the sheet metal products are placed in the feeding tray 4, and the feeding slide rail module 1 controls the feeding tray 4 to move inward to the inside of the three-axis slide rail module 2, so that the sheet metal parts in the feeding tray 4 correspond to the laser head 13. At the same time, the rotating mechanism contacts and starts the limiting plate 3. The rotating mechanism controls the two rotating rods 5 to rotate, and the two rotating rods 5 drive the two pressure frames 6 to rotate upward. The two pressure frames 6 cause the two pressure block assemblies 7 to rotate to the upper side of the feeding tray 4 to press and fix the sheet metal products in the feeding tray 4, so that the sheet metal products remain stable. The three-axis slide rail module 2 controls the laser head 13 to move and precisely cut the sheet metal products.

[0024] Specifically, the rotating mechanism includes a fixed rod 81, a shaped rack 82, a spring 83, and two gears 84. The fixed rod 81 is fixedly connected to the bottom end of the feeding disc 4. The shaped rack 82 is slidably connected to the fixed rod 81, and one end of the shaped rack 82 corresponds to the limiting plate 3. The spring 83 is sleeved on the circumferential surface of the fixed rod 81, and the spring 83 corresponds to the shaped rack 82. The two gears 84 are fixedly connected to the circumferential surfaces of the two rotating rods 5, and the two gears 84 mesh with the shaped rack 82 in an alternating manner.

[0025] In this embodiment, when the feeding tray 4 moves the sheet metal product to the lower side of the laser head 13, one end of the irregular rack rod 82 contacts the limiting plate 3. The limiting plate 3 causes the irregular rack rod 82 to slide on the fixed rod 81. The irregular rack rod 82 meshes to make the two gears 84 rotate in opposite directions and squeeze the spring 83. The two gears 84 respectively drive the two rotating rods 5 to rotate upward, thereby causing the two pressure frames 6 and the two pressure block assemblies 7 to rotate upward and press and fix the sheet metal product in the feeding tray 4 corresponding to the laser head 13, so that the laser head 13 can cut the sheet metal product.

[0026] Specifically, a rubber buffer block 9 is fixedly connected to one end of the limiting plate 3 near the feeding tray 4, and the rubber buffer block 9 corresponds to the irregular rack rod 82.

[0027] In this embodiment, the rubber buffer block 9 can reduce the impact force generated by the contact between the irregular rack rod 82 and the limiting plate 3, and provide a certain buffering and anti-collision effect for the irregular rack rod 82 and the limiting plate 3, thus protecting the irregular rack rod 82 and the limiting plate 3.

[0028] Specifically, a cylinder module 10 is fixedly connected to the bottom of the feeding tray 4, and a lifting plate assembly 11 is fixedly connected to the output end of the cylinder module 10, with the lifting plate assembly 11 located inside the feeding tray 4.

[0029] In this embodiment, after the sheet metal product is cut, the feeding slide rail module 1 controls the feeding tray 4 to move out from under the laser head 13, and the cylinder module 10 pushes the lifting plate assembly 11 to lift the sheet metal product, making it easier to remove the sheet metal product.

[0030] Specifically, a sensor 12 is fixedly connected to one side wall of the feeding tray 4.

[0031] In this embodiment, sensor 12 is used to detect sheet metal products and determine whether sheet metal products are present in the feeding tray 4.

[0032] Working principle: During laser cutting of sheet metal products, the sheet metal product is placed in the feeding tray 4. The feeding slide rail module 1 controls the feeding tray 4 to move inward to the inside of the three-axis slide rail module 2, so that the sheet metal part in the feeding tray 4 corresponds to the laser head 13. At the same time, one end of the irregular rack rod 82 contacts the limiting plate 3. The limiting plate 3 causes the irregular rack rod 82 to slide on the fixed rod 81. The irregular rack rod 82 meshes to make the two gears 84 rotate in opposite directions and compress the spring 83. The two gears 84 drive the two rotating rods 5 to rotate upward, thereby causing the two pressure frames 6 and the two pressure block assemblies 7 to rotate upward and press and fix the sheet metal product on the feeding tray. Inside the tray 4, corresponding to the laser head 13, the sheet metal product remains stable. The three-axis slide rail module 2 controls the multi-axis movement of the laser head 13 to precisely cut the sheet metal product. After the sheet metal product is cut, the feeding slide rail module 1 controls the feeding tray 4 to move out and reset from the underside of the laser head 13. The irregular rack rod 82 moves away from the limit plate 3. When the irregular rack rod 82 is not in contact with the limit plate 3, the elastic force of the spring 83 acts on the irregular rack rod 82, and the irregular rack rod 82 elastically resets, thereby causing the two gears 84 to drive the two rotating rods 5 to rotate and reset. The two pressure frames 6 drive the two pressure block assemblies 7 to rotate and open, so that the sheet metal product can be taken out from the feeding tray 4.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
