[0002] "CN 217913501 U" discloses "a clamping assembly for a laser cutting machine, comprising: a base frame, a support frame is fixedly arranged inside the base frame... a handle is fixedly connected to the middle part of the upper surface of the upper limit plate." The upper limit plate and the middle limit plate are pulled closer to each other by a thrust spring, so that the oblique tooth block in the middle part of the lower surface of the upper limit plate can be stuck in the oblique tooth groove on the upper surface of the support plate, which can effectively prevent the two upper limit plates from moving away from each other, resulting in a poor clamping effect of the clamping plate on the plate;

[0003] With respect to the above-mentioned related technologies, the inventor believes that the minimum spacing during adjustment is limited by the size of a single bevel tooth groove, which may result in certain limitations on adjustment and the defect of insufficient flexibility.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In order to solve the problem that the minimum spacing during adjustment is limited by the size of a single bevel tooth groove, which may lead to certain restrictions and lack of flexibility in adjustment, the present application provides a clamping component for a laser cutting machine.

[0007] A clamping component for a laser cutting machine comprises a cutting workbench, wherein the cutting workbench comprises a workbench, a plurality of support plates are arranged on the top of the workbench, a three-axis adjustment frame is arranged on the outer side of the support plate on the workbench, a laser cutting head is arranged at the lower end of the three-axis adjustment frame, the laser cutting head is located directly above the support plate, a plurality of oblique tooth grooves are arranged on both sides of the support plate, a clamping assembly is arranged on both sides of the workbench, the clamping assembly comprises a clamping piece arranged on the upper side of the support plate, a limiting piece which is engaged with the oblique tooth groove is movably arranged on the side of the two clamping pieces which are away from each other, and a plurality of guide rods are arranged on the clamping piece, and the end of the guide rod passes through the workbench and is slidably connected to the workbench.

[0008] Preferably, the clamping member comprises a clamping plate, and three ear plates are arranged at the lower end of the clamping plate, and the two ear plates located on the outer sides are respectively fixedly connected to the corresponding guide rods.

[0009] Preferably, a threaded rod is rotatably provided on one of the ear plates, the end of the threaded rod passes through the workbench and is threadedly connected to the workbench, and the end of the threaded rod is connected to a handwheel.

[0019] The following is combined with the accompanying drawings Figure 1-4 This application is described in further detail.

[0020] The present application embodiment discloses a clamping component for a laser cutting machine. Figure 1-4 A clamping component for a laser cutting machine comprises a cutting table 1, the cutting table 1 comprises a table 101, a plurality of support plates 102 are installed on the top of the table 101, a three-axis adjustment frame 2 is installed on the outer side of the support plate 102 on the table 101, a laser cutting head 3 is installed on the lower end of the three-axis adjustment frame 2, the laser cutting head 3 is located directly above the support plate 102, a plurality of oblique tooth grooves are provided on both sides of the support plate 102, a clamping assembly 4 is installed on both sides of the table 101, the clamping assembly 4 comprises a clamping piece 401 installed on the upper side of the support plate 102, a limiting piece 402 engaged with the oblique tooth groove is movably installed on the side of the two clamping pieces 401 away from each other, a plurality of guide rods 404 are installed on the clamping piece 401, and the end of the guide rod 404 passes through the table 101 and is slidably connected to the table 101;

[0021] By adopting the above technical solution, during adjustment, the limit member 402 will fall into the bevel groove on the support plate 102 under the action of gravity, and abut against the clamping member 401 at different angles by sliding to the slope of the bevel groove, thereby preventing the clamping member 401 from moving backward.

[0022] Reference Figure 3 The clamping member 401 includes a clamping plate 4011, and three ear plates 4012 are welded at the lower end of the clamping plate 4011. The two ear plates 4012 located on the outer side are respectively connected to the corresponding guide rods 404 through bolts. A threaded rod 403 is installed on one ear plate 4012 through a bearing. The end of the threaded rod 403 passes through the workbench 101 and is threadedly connected to the workbench 101. The end of the threaded rod 403 is connected to a hand wheel 5;

[0023] By adopting the above technical solution, the threaded rod 403 can be easily rotated by operating the hand wheel 5, thereby adjusting the position of the clamping member 401. Due to the effect of gravity, the limit member 402 can slide to abut the slope of the inclined tooth groove, thereby limiting the retreat of the clamping member 401 and improving the stability of the system.

[0024] Reference Figure 4 The upper end of the clamping plate 4011 is hinged to a plurality of hinge seats 4021, and the lower ends of the plurality of hinge seats 4021 are welded with a same limiting plate 4022, and the end of the limiting plate 4022 is provided with an inclined surface adapted to the oblique tooth groove, and the limiting plate 4022 is provided with a plurality of rotation grooves, and the guide rod 404 and the threaded rod 403 are respectively located in the corresponding rotation grooves;

[0025] By adopting the above technical solution, there is a certain movable gap at the hinge of the clamping plate 4011 and the hinge seat 4021, providing sufficient rotation space and abutment angle. Through the rotation groove, there is no interference between the limit member 402 and the threaded rod 403 and the guide rod 404, which facilitates the rotation of the limit member 402.

[0026] The implementation principle of a clamping component for a laser cutting machine in an embodiment of the present application is as follows: when the distance between the two clamping members 401 is reduced, the hand wheel 5 is directly rotated in the forward direction, so that the threaded rod 403 drives the clamping member 401 to drive the limiting member 402 to move toward the middle, so that the limiting plate 4022 moves along the support plate 102, and the limiting plate 4022 falls into the oblique tooth groove on the support plate 102 under the action of gravity, and abuts against the clamping member 401 at different angles by sliding to the slope of the oblique tooth groove, thereby preventing the clamping member 401 from retreating, and clamping and limiting the workpiece through the clamping plate 4011. When the distance between the two clamping members 401 is increased, the limiting member 402 is flipped upward, and then the hand wheel 5 is rotated in the reverse direction, so that the threaded rod 403 drives the clamping member 401 to drive the limiting member 402 to move to both sides.
