[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] To address the issues of varying metal sheet thicknesses requiring flexible fixing structures during laser cutting, and the potential for vibrations caused by the metal sheet's own quality issues, which could lead to laser cutting failures and a decrease in the yield rate of finished products, the following embodiments are proposed.

[0026] This utility model provides, for example Figures 1 to 5 The laser cutting fixture shown includes a support frame 1, with C-shaped grooves 2 symmetrically arranged on the top of the support frame 1. A moving component 3 is arranged inside the C-shaped grooves 2, a cutting component 4 is arranged on the C-shaped grooves 2, and a fixing component 5 is symmetrically arranged on the C-shaped grooves 2. An operating table 6 is fixedly arranged on the C-shaped grooves 2, and a transmission component is arranged outside the operating table 6. The transmission component transports the metal plate to be cut to the operating table 6.

[0027] By setting the fixing component 5, the fixing height can be changed, which can fix metal plates of different thicknesses; in addition, when the cutting component 4 is cutting, the fixing component 5 can also screen out the metal plates with defects, ensuring the finished product qualification rate.

[0028] like Figures 2-3 As shown, the fixing component 5 includes a telescopic cylinder 503. A telescopic column 504 is slidably disposed within the output shaft of the telescopic cylinder 503. The telescopic column 504 can extend and slide within the output shaft of the telescopic cylinder 503, thereby driving the height of the pressing block 505 to be adjusted slightly. With the elastic force of the spring 506, it fixes metal plates of different thicknesses. A spring 506 is disposed on the outer side of the telescopic column 504. A pressing block 505 is fixedly disposed at the bottom end of the telescopic column 504. The interior of the pressing block 505 gradually expands from top to bottom, including an upper vertical section, an inclined section, and a lower vertical section. The lower vertical section serves to initially determine the position of the metal plate. The four corners of the metal plate must be within the range of the lower vertical section. The upper vertical section is in contact with the four corners of the metal plate and serves to press and fix it. The inclined section is used to correct the position of the metal plate. The operating table 6 is provided with a groove corresponding to the pressing block 505, so that when the upper vertical section is fixed to the metal plate, the inclined section and the lower vertical section can enter the groove to ensure the pressing and fixing effect of the upper vertical section. One end of the spring 506 is fixedly set at the end of the output shaft of the telescopic cylinder 503, and the other end is fixedly set on the pressing block 505; a right angle plate 501 is fixedly set on the C-shaped groove 2, and a fixing frame 502 is fixedly set on the side of the right angle plate 501, and the telescopic cylinder 503 is set in the fixing frame 502.

[0029] During use, since the metal plate may be placed in a slightly off position after being loaded onto the operating table 6, the metal plate is first placed within the shaded area formed by the four lower vertical sections during the fixing process. The output shaft of the telescopic cylinder 503 is extended, causing the pressing block 505 to descend. The inclined section will first contact the four corners of the metal plate. As it continues to descend, the inclined section adjusts the angle of the metal plate until the upper vertical section is in contact with the four corners of the metal plate, thus fixing the metal plate. Then, it is lowered a certain distance so that the telescopic column 504 penetrates deeper into the output shaft of the telescopic cylinder 503, causing the spring 506 to be compressed. The elastic force of the spring 506 assists the pressing block 505 in fixing the metal plate better.

[0030] Before cutting, the tooling equipment is inspected to ensure it is operating normally. During the cutting of the metal plate, the compression of spring 506 exhibits high-frequency changes, indicating that spring 506 is vibrating. This suggests that the metal plate is vibrating, causing changes in the compression of spring 506. Therefore, it can be inferred that the metal plate has quality issues such as uneven surface, defects, or uneven thickness, leading to uneven stress and vibration during cutting. At this point, the operation of moving component 3 and cutting component 4 is stopped, the cutting step is halted, the metal plate is unloaded, and the defective component is marked.

[0031] By setting a spring 506 in conjunction with the telescopic column 504, the spring 506 is compressed to generate elastic force to assist the pressing block 505 in pressing and fixing the metal plate better. At the same time, it can also press and fix metal plates of different thicknesses. Furthermore, by measuring the frequency of changes in the compression amount of the spring 506, it can determine whether there are quality problems with the current metal plate, thereby screening out metal plates with quality problems and avoiding laser cutting failures and a decrease in the pass rate of finished products.

[0032] like Figures 4-5 As shown, the cutting assembly 4 includes parallel supporting channel steels 401. A transverse channel steel 402 is fixedly mounted on the top of the supporting channel steel 401. Vertical plates 403 are mounted at both ends of the transverse channel steel 402. A transverse screw 404 is rotatably mounted on the vertical plate 403. A moving block 405 is rotatably connected to the transverse screw 404. An elongated hole is opened on the bottom surface of the supporting channel steel 401. The bottom of the moving block 405 passes through the elongated hole and extends downwards, and is fixedly connected to a telescopic rod 406. When the moving block 405 reciprocates, it drives the telescopic rod 406 and the laser unit 407 to move synchronously. The output end of the telescopic rod 406 extends and retracts, causing the laser unit 407 to rise and fall, moving closer to or away from the metal plate. The output end of the telescopic rod 406 is fixedly connected to the laser unit 407. 07; A horizontal motor 408 is fixedly connected to either end of the horizontal screw 404. The horizontal motor 408 is fixedly mounted on the horizontal channel steel 402. A moving wheel 409 is fixedly installed at the bottom of the supporting channel steel 401. The moving component 3 includes a limiting block 301 fixedly installed at both ends of the C-shaped groove 2. A longitudinal screw 302 is rotatably connected to the limiting block 301. A drive wheel 303 is threadedly connected to the longitudinal screw 302. A transmission column 304 is fixedly installed on the top surface of the drive wheel 303. The top end of the transmission column 304 is fixedly connected to the moving wheel 409. When the drive wheel 303 moves, it drives the moving wheel 409 to move along the C-shaped groove 2 through the transmission column 304. A longitudinal motor 305 is fixedly connected to either end of the longitudinal screw 302. The cutting component 4 controls the horizontal movement position, and the moving component 3 controls the vertical movement position, forming a coordinate system, so that the position of the laser unit 407 can be moved to perform cutting according to the instructions of the central control panel.

[0033] In use, based on the coordinate position corresponding to the cutting shape sent by the central control console, the longitudinal motor 305 is controlled to drive the longitudinal screw 302 to rotate, thereby driving the drive wheel 303 to move. The drive wheel 303 drives the cutting assembly 4 to move longitudinally along the C-shaped groove 2 through the transmission column 304. The transverse motor 408 is controlled to drive the transverse screw 404 to rotate, thereby driving the moving block 405 to move laterally. This, in turn, drives the laser unit 407 to move synchronously through the telescopic rod 406. After moving into position, the output end of the telescopic rod 406 is controlled to extend, causing the laser unit 407 to descend and approach the metal plate for cutting.

[0034] The working principle of this utility model is as follows: First, a metal plate is fixed. After the metal plate to be cut is transported to the operating table 6 through an external transmission component, the metal plate is moved to the shaded area formed by four lower vertical sections. The output shaft of the telescopic cylinder 503 is extended, which drives the pressing block 505 to descend. The inclined section will first contact the four corners of the metal plate. As it continues to descend, the inclined section adjusts the position and angle of the metal plate until the upper vertical section is in contact with the four corners of the metal plate, thus fixing the metal plate. Then, it descends a certain distance, so that the telescopic column 504 penetrates into the inside of the output shaft of the telescopic cylinder 503, causing the spring 506 to be compressed. The elastic force of the spring 506 assists the pressing block 505 in fixing the metal plate better.

[0035] Next, the metal plate is cut. Based on the coordinate position corresponding to the path of the cutting shape sent by the central control console, the longitudinal motor 305 is controlled to drive the longitudinal screw 302 to rotate, thereby driving the drive wheel 303 to move. The drive wheel 303 drives the entire cutting assembly 4 to move longitudinally along the C-shaped groove 2 through the transmission column 304. The transverse motor 408 is controlled to drive the transverse screw 404 to rotate, thereby driving the moving block 405 to move laterally. This, in turn, drives the laser unit 407 to move synchronously through the telescopic rod 406. After moving into position, the output end of the telescopic rod 406 is controlled to extend, causing the laser unit 407 to descend and approach the metal plate for cutting.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
