Description

Technical Field

[0001] This utility model relates to the field of three-dimensional laser cutting machine technology, specifically a dual-worktable three-dimensional laser cutting machine. Background Technology

[0002] 3D laser cutting machines utilize the flexible movement of industrial robots or multi-axis linkage mechanisms to accurately position the fiber laser cutting head at the workpiece's cutting location. The laser generated by the laser generator is transmitted to the cutting head via optical fiber, and then focused by a focusing system to form a high-energy-density spot on the workpiece surface, causing the workpiece material to rapidly melt or vaporize, thus achieving cutting. During the cutting process, the control system precisely controls the cutting head's movement trajectory and speed, as well as parameters such as laser power and pulse frequency, to ensure cutting quality and precision.

[0003] In the existing technology, a fixed pressure plate and corresponding bolt holes are set on the transport table. After the sheet is placed on the transport table, the pressure plate is lowered by tightening the bolts, thereby pressing the sheet tightly against the surface of the transport table. When processing sheet in batches, the operation of tightening and loosening the bolts is too many, which will affect the processing efficiency. For example, if a large number of sheet needs to be cut, the frequent tightening and loosening of the bolts will increase the fixing and disassembly time of each sheet, reducing work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a dual-table three-dimensional laser cutting machine to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a dual-worktable three-dimensional laser cutting machine, including a worktable body, a transport table, a laser cutting machine frame, a mounting plate symmetrically mounted on the top of the transport table; clamping blocks symmetrically arranged on the top of the transport table, the cross-section of the clamping blocks being a right-angled trapezoid, and the inclined surfaces of the two clamping blocks being inclined; an elastic element fixedly installed between the mounting plate and the clamping blocks, the elastic element being composed of multiple Z-shaped elastic blocks; a support block fixedly installed on the side away from the elastic element; and grooves formed at both ends of the support block, the grooves being U-shaped.

[0006] Furthermore, a guide telescopic rod is fixedly installed between the mounting plate and the clamping block. The fixed end of the guide telescopic rod is fixedly installed on the mounting plate, and the telescopic end of the guide telescopic rod is fixedly installed on the clamping block.

[0007] Furthermore, a slide rail is fixedly installed on the top of the workbench body, and a slide groove adapted to the slide rail is opened at the bottom of the transport table, with ball bearings provided on the inner top wall of the slide groove.

[0008] Furthermore, limit blocks are fixedly installed at both ends of the chute.

[0009] Furthermore, a servo motor is installed between the two worktable bodies. The drive end of the servo motor is connected to a roller, and another roller is located at the other end near the slide rail. A transmission belt connects the two rollers.

[0010] Furthermore, fixing blocks are fixedly installed on both sides of the transmission belt, and the fixing blocks are fixedly installed on one side of the transport platform.

[0011] Furthermore, the elastic element is made of spring steel.

[0012] Furthermore, the laser cutting machine frame is positioned above the worktable body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, the worker places the sheet material on top of the transport table and pushes it along the inclined surface of the mounting plate to the top of the support block. During this process, the elastic element is compressed, and its Z-shaped elastic block provides clamping force from the side to stabilize the sheet material. After laser cutting is completed, the transport table is moved away, and the worker inserts their fingers into the U-shaped grooves at both ends of the support block to grasp the bottom of the sheet material and lift it up, making it easy to remove the sheet material and improving the convenience and efficiency of loading and unloading.

[0015] 2. In this invention, the guide telescopic rod ensures that the clamping block moves in a straight line, preventing offset or wobbling, thus guaranteeing precise positioning during the cutting process. This is crucial for the high precision requirements of laser cutting; accurate positioning helps improve cutting quality, especially when cutting complex-shaped workpieces, allowing for a more precise cutting path.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution:

[0023] See Figures 1-4 As shown, a dual-worktable three-dimensional laser cutting machine includes a worktable body 1, a transport table 2, a laser cutting machine frame 15, a mounting plate 3 symmetrically mounted on the top of the transport table 2; clamping blocks 5 symmetrically arranged on the top of the transport table 2, the cross-section of the clamping blocks 5 being a right-angled trapezoid, and the inclined surfaces of the two clamping blocks 5 being inclined; an elastic element 4 fixedly installed between the mounting plate 3 and the clamping blocks 5, the elastic element 4 being composed of multiple Z-shaped elastic blocks; a support block 6 fixedly installed on the side away from the elastic element 4; and grooves 7 formed at both ends of the support block 6, the grooves 7 being U-shaped.

[0024] The operator places the sheet material on top of the transport table 2 and pushes it along the inclined surface of the mounting plate 3, allowing it to fall smoothly onto the top of the support block 6. During this process, the elastic element 4 undergoes compression deformation due to the pressure of the sheet material. Its multiple Z-shaped elastic blocks work together to apply force towards the top of the mounting plate 3, thereby providing a stable clamping force from the side of the sheet material, ensuring that the sheet material remains stable during laser cutting. After the laser cutting operation is completed, the transport table 2 is moved away from the laser cutting head area. At this time, the operator can insert their fingers into the U-shaped grooves 7 at both ends of the support block 6, firmly grasp the bottom of the sheet material, and lift it upwards, thus conveniently removing the sheet material from the fixing device, effectively improving the convenience and efficiency of sheet material loading and unloading.

[0025] See Figure 3 A guide telescopic rod 16 is fixedly installed between the mounting plate 3 and the clamping block 5. The fixed end of the guide telescopic rod 16 is fixedly installed on the mounting plate 3, and the telescopic end of the guide telescopic rod 16 is fixedly installed on the clamping block 5.

[0026] In a dual-table 3D laser cutting machine, the guide telescopic rod 16 plays a crucial role in guiding the motion. This structure connects the mounting plate 3 and the clamping block 5, allowing the relevant components to move in a predetermined direction during operation. The guide telescopic rod 16 ensures that the clamping block 5 moves in a straight line, preventing offset or wobbling, thus guaranteeing precise positioning during the cutting process. This is essential for the high precision requirements of laser cutting; accurate positioning helps improve cutting quality, especially when cutting complex-shaped workpieces, allowing for a more precise cutting path.

[0027] See Figure 3 The top of the workbench body 1 is fixedly equipped with a slide rail 9, and the bottom of the transport table 2 is provided with a slide groove 8 that is compatible with the slide rail 9. The inner top wall of the slide groove 8 is provided with ball bearings.

[0028] The ball bearings installed on the inner top wall of the slide rail 8 significantly reduce the friction between the transport table 2 and the slide rail 9. The presence of the ball bearings transforms the original sliding friction into rolling friction; according to the principles of physics, the frictional force of rolling friction is much less than that of sliding friction. This makes the movement of the transport table 2 on the slide rail 9 easier and smoother. For example, when transporting heavier workpieces, the lower friction makes the transport table 2 easier to drive, reducing the load on the drive unit, improving the energy efficiency of the equipment, and also reducing wear caused by friction between components.

[0029] See Figure 3 Limiting blocks 10 are fixedly installed at both ends of the slide 8.

[0030] In a dual-table 3D laser cutting machine, limit blocks 10 are fixedly installed at both ends of the slide rail 8, effectively preventing the transport table 2 from sliding off the slide rail 9 during movement. When the transport table 2 moves along the slide rail 9 under the drive of the power unit, the limit blocks 10 act as boundary restrictions, ensuring that the movement range of the transport table 2 is within a safe and predetermined range. For example, during high-speed transport or frequent back-and-forth transport of workpieces, the transport table 2 may move beyond its range due to inertia or control system malfunctions. The limit blocks 10 act as a barrier, preventing the transport table 2 from detaching from the slide rail 9, thereby ensuring the normal operation of the equipment.

[0031] See Figure 4 A servo motor 11 is provided between the two worktable bodies 1. The drive end of the servo motor 11 is connected to a roller 12. Another roller 12 is located at the other end near the slide rail 9. A transmission belt 13 is connected between the two rollers 12.

[0032] In a dual-table 3D laser cutting machine, a servo motor 11 drives the transport table 2 via a drive roller 12 and a transmission belt 13, providing precise power transmission. The servo motor 11 has high-precision position and speed control capabilities; it can precisely adjust the rotational speed of the roller 12 according to the control system's instructions, thereby precisely controlling the movement speed of the transmission belt 13. This allows the transport table 2 to move precisely along the slide rail 9, ensuring the workpiece is accurately transported to the designated position below the laser cutting head. For example, when cutting high-precision electronic components, even a slight positional deviation of the transport table 2 can lead to cutting failure, and this precise power transmission effectively avoids this situation.

[0033] See Figure 4 Fixing blocks 14 are fixedly installed on both sides of the transmission belt 13, and the fixing blocks 14 are fixedly installed on one side of the transport platform 2.

[0034] This connection method enhances the stability of the connection between the drive belt 13 and the conveyor table 2. When the drive belt 13 moves under the drive of the roller 12, the fixing block 14 can firmly transmit power to the conveyor table 2, preventing loosening or slippage between the conveyor table 2 and the drive belt 13. For example, during long-term operation or high-speed operation of the equipment, a stable connection can ensure that the conveyor table 2 always moves accurately with the drive belt 13, which is crucial for ensuring the accuracy of the workpiece transportation position.

[0035] See Figure 1-3 The elastic element 4 is made of spring steel.

[0036] Spring steel, as the material of elastic element 4, has a high elastic modulus. This means that when subjected to a certain external force, elastic element 4 can produce corresponding elastic deformation and can return to its original shape after the external force is removed.

[0037] See Figure 1 The laser cutting frame 15 is positioned above the worktable body 1.

[0038] For operators, the laser cutting frame 15's position above the worktable body 1 facilitates operation and observation of the cutting process. Operators can directly observe the relative position of the cutting head and the workpiece from around the worktable, enabling them to promptly identify problems during the cutting process, such as whether the cutting head is aligned with the workpiece or whether the cutting path is correct. Furthermore, during loading and unloading operations, operators can conveniently perform these operations from beside the worktable, eliminating the need for additional complex movements to approach the cutting area, thus improving operational convenience and work efficiency.
