[0002] In the field of laser cutting, laser cutting machines are key equipment for achieving precise material cutting. Their core working components include a worktable (toothed table) for supporting the workpiece. The rack on the worktable serves as both workpiece support and transmission adapter, significantly impacting cutting accuracy and equipment stability.
[0003] In traditional laser cutting machines, the assembly structure of the rack and table often suffers from problems such as loosening and displacement of the rack after installation due to its simple fixing method and insufficient limiting. This leads to unstable workpiece support during cutting, affecting the accuracy of the cutting trajectory and reducing product quality. At the same time, the conventional fixing structure makes the disassembly and assembly of the rack cumbersome and time-consuming when maintaining and replacing it.

[0032] 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.
[0033] Please see Figure 1-5In this embodiment of the utility model, a laser cutting machine includes a frame 1, a worktable 2, a laser cutting module 6, and an elastic blocking block 7. These components work together to ensure stable and efficient cutting operations. The key structures, connections, and functions are described below:
[0034] The frame 1 serves as the basic support, supporting the worktable 2. On the support frame 3 of the worktable 2, mounting slots 5, matching the number of racks 4, are formed on the two inner sidewalls along its length. The racks 4 are elongated, with their two sides precisely fitted into the corresponding mounting slots 5, completing the assembly with the support frame 3. Simultaneously, a rib 13 is provided in the middle area of the support frame 3, with mounting slots 14 on it. The size and shape of these ribs 13 are adapted to the racks 4, and the middle portion of the racks 4 is embedded in these mounting slots 14. The mounting slots 5 limit the movement of the racks 4 on both sides, and the mounting slots 14 limit the movement of the racks 4 in the middle, ensuring the racks 4 are securely mounted on the support frame 3 and preventing them from shifting due to external forces during cutting operations.
[0035] The top tooth surface of rack 4 is used to place the workpiece to be cut. The tooth surface extends along the length of rack 4, and the tooth surfaces of adjacent racks 4 are at the same horizontal height, ensuring that the workpiece is placed stably and providing a stable support base for precise cutting, so that the workpiece is not easily displaced due to uneven support surface during the cutting process.
[0036] The elastic plug 7 is installed at the end of the mounting groove 5, and is L-shaped, consisting of a horizontal part 8 and a vertical part 9. The support frame 3 has a first groove 10 (adapted to the vertical part 9) and a second groove 11 (adapted to the horizontal part 8), and the second groove 11, the first groove 10, and the mounting groove 5 are connected in sequence. During installation, the vertical part 9 is inserted into the first groove 10, and the horizontal part 8 is inserted into the second groove 11. The elastic plug 7, with its own elasticity, continuously applies force to the end of the rack 4, pressing the rack 4 tightly into the mounting groove 5, thus strengthening the fixing effect of the rack 4. In addition, on the side of the support frame 3 away from the first groove 10, there is a handle groove 12 that communicates with the second groove 11. When the rack 4 needs to be disassembled for maintenance, the operator can use the handle groove 12 to move the horizontal part 8, which will allow the elastic plug 7 to disengage from the support frame 3. At this time, the rack 4 is no longer subjected to the abutting force of the elastic plug 7, and the replacement and maintenance of the rack 4 can be easily completed, simplifying the maintenance process.
[0037] The laser cutting module 6 consists of a drive mechanism 15 and a laser cutting head 16, with the drive mechanism 15 and laser cutting head 16 connected by a transmission. During operation, the drive mechanism 15 drives the laser cutting head 16 to move along directions parallel and perpendicular to the length of the rack 4, cutting the workpiece according to a preset trajectory to meet the cutting requirements of workpieces of different sizes and shapes. The drive mechanism 15 consists of an X, Y, and Z three-axis drive system, which, through servo motors, ball screws, synchronous belts, and other transmission components, controls the movement of the laser cutting head 16 along the length of the rack 4, perpendicular to the rack 4, and vertically, respectively, achieving precise positioning in three-dimensional space.
[0038] The elastic plug 7 is made of elastic materials such as rubber, spring steel sheet, or elastic plastic. These materials can undergo elastic deformation under stress, generating elastic force, and have a certain degree of wear resistance and fatigue resistance. They can maintain their elasticity stably during long-term use, continuously providing reliable clamping force for the rack 4 and ensuring structural stability.
[0039] In practical applications, the workpiece to be cut is placed on the tooth surface of the rack 4, and the laser cutting head 16 moves along a preset trajectory under the drive of the drive mechanism 15 to complete the cutting operation. When the rack 4 needs to be replaced, the horizontal part 8 of the elastic block 7 is moved by the handle groove 12 to disengage it from the support frame 3, and the rack 4 can be removed for replacement. During installation, the rack 4 is embedded into the mounting groove 5 and the assembly groove 14, and then the elastic block 7 is embedded into the corresponding groove, using its elastic force to fix the rack 4.
[0040] In summary, through the synergistic effect of the mounting groove 5, the assembly groove 14, and the elastic block 7, the rack 4 achieves multi-point limiting and elastic fastening, effectively preventing the rack 4 from loosening and shifting, and improving cutting accuracy. The setting of the intermediate rib 13 significantly enhances the support rigidity of the rack 4, improves its resistance to deformation, and ensures long-term processing consistency. The detachable design of the handle groove 12 and the elastic block 7 greatly shortens the replacement time of the rack 4, improves maintenance efficiency, and reduces downtime costs. The elastic block 7 uses low-cost materials to replace traditional bolt fixing, while simplifying the assembly process and reducing labor costs.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
