Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0027] First embodiment

[0028] As Figs. 1-2As shown, a positioning device of a laser cutting machine includes a laser cutting machine, which includes a workbench 1 provided with a mounting frame 2, the mounting frame 2 is provided with a laser cutting head 4 through a first lifting assembly 3, and the workbench 1 is provided with movable limiting assemblies towards the center of the workbench 1 on four sides. The movable part of the first lifting assembly 3 is fixedly connected with at least one second lifting assembly 601, and the movable part of the second lifting assembly 601 is provided with a pressing plate 602.

[0029] As shown, Figs. 1-2 The laser cutting machine is the core of the entire device, responsible for emitting high-energy laser beams for cutting operations. The workbench 1 is a platform for placing the pieces to be cut, its surface is flat and large enough to accommodate pieces of different sizes. The mounting frame 2 is fixed on the workbench 1, used to support the first lifting assembly 3. The first lifting assembly 3 (such as a lifting electric cylinder) is connected to the workbench 1 through the mounting frame 2, and its movable part (i.e. the lifting part) is used to adjust the height of the laser cutting head 4. By precisely controlling the lifting amount of the first lifting assembly 3, cutting operations on pieces of different heights can be realized. The second lifting assembly 601 is fixedly connected to the movable part of the first lifting assembly 3 and lifts together with the first lifting assembly 3. The movable part of the second lifting assembly 601 is provided with a pressing plate 602, which is used to press the piece to be cut in the vertical direction, ensuring that it remains stable during the cutting process. By adjusting the lifting amount of the second lifting assembly 601, the contact force between the pressing plate 602 and the piece to be cut can be adjusted to adapt to pieces of different materials and thicknesses. The workbench 1 is provided with movable limiting assemblies (such as clamping air cylinders 501 and clamping plates 502) on four sides towards the center of the workbench 1. These movable limiting assemblies can move in the horizontal direction to clamp and position the piece to be cut. When the piece to be cut is placed on the workbench 1, the movable limiting assemblies will move towards the center and tightly fit around the piece to be cut, thereby firmly fixing it on the workbench 1. This design can ensure that the piece to be cut does not shift or shake during the cutting process, improving cutting precision.

[0030] As shown, Figs. 1-2 During the laser cutting process, first, according to the size and shape of the piece to be cut, adjust the position and clamping force of the movable limiting assemblies to ensure that the piece to be cut is firmly fixed on the workbench 1. Then, by precisely controlling the lifting amount of the first lifting assembly 3 and the second lifting assembly 601, adjust the height and contact force of the laser cutting head 4 and the pressing plate 602. Finally, start the laser cutting machine for cutting operations. During the entire cutting process, the movable limiting assemblies and the pressing plate 602 jointly ensure the stability and precision of the piece to be cut, thereby improving cutting quality and efficiency.

[0031] As shown, Figs. 1-2As shown, the movable limiting assembly includes clamping cylinders 501, the movable parts of the clamping cylinders 501 are all towards the center of the workbench 1, and the movable parts of the clamping cylinders 501 are fixedly connected with clamping plates 502. The clamping cylinder 501 is a kind of pneumatic actuator, and the movable part (usually the piston rod) can make linear reciprocating motion in the cylinder body. In this technical solution, the movable parts of the clamping cylinders 501 are all towards the center of the workbench 1, which means that when the cylinder is activated, its movable part will move towards the center of the workbench 1. The clamping plate 502 is fixedly connected to the movable part of the clamping cylinder 501, so when the movable part of the clamping cylinder 501 moves, the clamping plate 502 will also move. This design allows the clamping plate 502 to move from the four sides of the workbench 1 to the center to clamp and position the to-be-cut piece placed on the workbench 1.

[0032] As shown in Figs. 1-2 The clamping cylinder 501 is provided with a connecting frame 701 between the clamping plate 502 and the second kidney function assembly and the pressing plate 602, and the connecting frame 701 is triangular. The connecting frame 701 is a connecting structure between the clamping cylinder 501 and the clamping plate 502, and between the (corrected) second lifting assembly 601 and the pressing plate 602. In this technical solution, the connecting frame 701 is triangular. The triangular structure has the characteristics of high stability and strength, and can withstand large force and torque, so it is very suitable for connecting and supporting these key components. The triangular connecting frame 701 not only enhances the connection strength between the clamping cylinder 501 and the clamping plate 502, but also allows a certain flexibility between them. This flexibility is crucial for adapting to different shapes and sizes of to-be-cut pieces.

[0033] As shown in Figs. 1-2 The connecting frame 701 is provided with three connecting ends 702 with external threads, and the pressing plate 602 and the two sides and the center of the back of the pressing plate 602 are rotatably connected with internal thread sleeves 703, and the internal thread sleeves 703 are matched with the external threads. The pressing plate 602 and the two sides and the center of the back of the pressing plate 602 are provided with internal thread sleeves 703, which are matched with the external thread ends to form a rotatable adjusting thread connection. When the internal thread sleeve 703 is connected with the external thread end, the height adjustment of the pressing plate 602 or the pressing plate 602 relative to the connecting frame 701 can be realized by rotating the internal thread sleeve 703. This adjustment mechanism is crucial for ensuring that the pressing plate 602 or the pressing plate 602 can accurately and stably apply pressure to the to-be-cut piece.

[0034] As shown in Figs. 1-2As shown, the outer wall of the internally threaded sleeve 703 is designed as a hexagonal prism. The outer wall of the internally threaded sleeve 703 is designed as a hexagonal prism, which facilitates rotation adjustment using a wrench, screwdriver or other hexagonal tools. The hexagonal shape provides sufficient gripping surface, so that the operator can more easily apply torque to accurately adjust the position and height of the pressing plate 602. In addition, the hexagonal shape also has a certain anti-rotation function, that is, the internally threaded sleeve 703 is not easy to rotate due to accidental touch without using tools.

[0035] As shown, Figs. 1-2 The first lifting assembly 3 and the second lifting assembly 601 are both designed as lifting electric cylinders. In this technical solution, the first lifting assembly 3 and the second lifting assembly 601 both use lifting electric cylinders as driving elements, realizing precise control of the height of the laser cutting head 4 and the pressing plate 602. The precise control characteristics of the lifting electric cylinder help to ensure that the laser cutting head 4 always maintains the optimal distance from the workpiece during the cutting process, thereby improving the cutting quality and efficiency. At the same time, the smooth running characteristics of the lifting electric cylinder also help to reduce vibration and noise during the cutting process, improving the stability and reliability of the entire laser cutting machine.

[0036] Second embodiment

[0037] As shown, Fig. 3 The back surface of the clamping plate 502 and the pressing plate 602 is provided with a reinforcing rib 801, and the front surface of the clamping plate 502 and the pressing plate 602 is provided with a plurality of anti-skid recesses 802, which are arranged in a rectangular array. The reinforcing rib 801 is a structural reinforcing element, which is usually used to increase the bending strength and stiffness of the plate. The reinforcing rib 801 arranged on the back surface of the clamping plate 502 and the pressing plate 602 can effectively improve the carrying capacity of these plate parts and prevent deformation during clamping or pressing. The design of the reinforcing rib 801 also helps to disperse stress and reduce local stress concentration when the plate is under stress, thereby prolonging the service life. The anti-skid recess 802 is a small groove opened on the front surface of the clamping plate 502 and the pressing plate 602, which is used to increase the friction between the plate and the workpiece. The plurality of anti-skid recesses 802 are arranged in a rectangular array, which ensures that the clamping plate 502 and the pressing plate 602 can provide uniform clamping force or pressing force when in contact with the workpiece. The design of the anti-skid recess 802 helps to prevent the workpiece from slipping or shifting during the cutting process, thereby improving the cutting accuracy and safety.

[0038] The above is only a specific embodiment of the present application, but the technical features of the present application are not limited to this. Any simple change, equivalent replacement or modification made on the basis of the present application to solve basically the same technical problem and achieve basically the same technical effect is covered by the protection scope of the present application.
