For example, after the workpiece is placed at the processing station, it must first be aligned by the mechanical claw. After alignment, the mechanical claw must be reset to the initial position before the cutting head of the laser cutting machine can intervene in the operation. The process is cumbersome and time-consuming. Utility Model Content

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application usually described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0018] The utility model discloses a laser cutting machine with automatic workpiece correction, which is mainly used in scenarios where a traditional laser cutting machine with automatic workpiece correction needs to introduce a separate mechanical claw to align the workpiece during use, and the operation process is complicated, which affects the cutting efficiency of the laser cutting machine.

[0020] Cleaning mechanism: The cleaning mechanism is arranged on the top of the processing platform 2.

[0021] The laser 5 is electrically connected to the cutting head 10 .

[0022] The clamping seat 9 is in contact with the processing platform 2; during the process of the two clamping seats 9 approaching and separating from each other, the ball provides active support to prevent the clamping seat 9 from being stuck on the processing platform 2 due to excessive friction.

[0023] During actual use, the electric telescopic rod 6 will be extended and retracted to drive the cutting head 10 to rise and fall, so as to ensure that the laser beam accurately hits the cutting position. During the lifting and lowering process of the electric telescopic rod 6, the movable rod 8 can be driven to pull the movable block to slide, thereby realizing the movement of the position of the clamping seat 9 at one end. As the electric telescopic rod 6 rises, the two clamping seats 9 will approach each other under the linkage traction of the movable rod 8, thereby realizing the clamping and alignment of the workpiece. As the electric telescopic rod 6 descends, the two clamping seats 9 will separate towards each other. After the workpiece is aligned, the cutting operation can be performed by the cutting head 10.

[0024] It should be noted that electric slide rails 3 are provided on both sides of the top outer wall of the processing platform 2, and sliders are slidably connected to the inner walls of the two electric slide rails 3. The cross frame 4 is installed on the top outer walls of the two sliders. Through the sliding cooperation between the slider and the electric slide rail 3, the cutting head 10 can be driven to cut in an orderly manner along the sliding direction of the slider.

[0025] Reference Figure 3 and Figure 4 In a preferred embodiment, the cleaning mechanism includes a support table 7 arranged on the inner side wall of the processing platform 2, and side slide rails 14 are provided on the outer walls on both sides of the support table 7. The two side slide rails 14 are slidably connected to the inner walls on both sides of the processing platform 2, and a storage groove is provided on the top outer wall of the support table 7. The bottom inner wall of the storage groove is provided with support cones 16 distributed at equal distances. Limiting steps 12 are provided on both sides of the top outer wall of the storage groove, and mold pads 11 distributed at equal distances are provided on the limiting steps 12. The top of the mold pad 11 is flush with the top of the processing platform 2.

[0026] Specifically, by setting the support cone 16 in conjunction with the mold pad 11, a flat support structure can be formed on the processing platform 2. The structure is flush with the support table 7, which is convenient for the linkage alignment mechanism to align the workpiece and also convenient for the processing debris to leak into the storage groove, and has strong adaptability.

[0027] It should be noted that the mold pad 11 provided in the present solution is limited and movably placed in cooperation with the limiting step 12, and when different shapes need to be cut, other mold pads 11 can be used to replace them.

[0028] Among them, an invisible handle 13 is provided on the outer wall of one side of the support platform 7, and a limit block is also provided on the outer wall of one side of the support platform 7, and a limit screw 15 is provided on the inner wall of the limit block.

After the processing is completed, the locking state of the limit screw 15 can be released, the support platform 7 can be removed, and the debris in the internal storage groove can be cleaned.

[0029] Working principle: When in use, first select a suitable mold pad 11 according to processing needs and place it on the limiting step 12 on the support table 7, then load the workpiece to be cut along the arrangement direction of the mold pad 11 in turn, and then start the electric slide rail 3 and the electric telescopic rod 6. The electric telescopic rod 6 drives the cutting head 10 to telescope and focus up and down in an orderly manner, so as to facilitate accurate cutting of the workpiece. During the extension and retraction process of the electric telescopic rod 6, as the electric telescopic rod 6 rises, the two clamping seats 9 will approach each other under the linkage traction of the movable rod 8, thereby realizing the clamping and alignment of the workpiece, combining the alignment operation with the pretreatment process before the cutting operation, avoiding a separate alignment operation, and improving work efficiency.

[0030] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
