[0002] Laser cutting is a technology that uses a high-energy-density laser beam to irradiate the surface of a material, causing it to melt, vaporize, or reach its combustion point, thereby achieving cutting. During laser cutting, ensuring the workpiece is correctly and stably fixed is crucial for guaranteeing cutting quality. If the workpiece shifts or deforms during cutting, it will increase cutting errors, affecting the quality and dimensional accuracy of the finished product. Traditional high-power laser cutting positioning systems have the following problems:

[0029] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please see Figure 1-4 The present invention is a positioning device for high-power laser cutting, including a support platform 200, a linear adjustment component 300 disposed on the upper edge of the support platform 200, and a clamping component 400 for workpiece positioning.

[0032] The support platform 200 includes a hollow table surface 201, an extension plate 202 integrally disposed on the side of the hollow table surface 201, a support seat 204 fixed to the lower side of the hollow table surface 201, and a transmission seat 203 fixed to the lower middle of the hollow table surface 201. The support platform 200 serves as the actual laser cutting processing location for the workpiece to be processed. The hollow design of its hollow table surface 201 not only reduces the weight of the support platform 200, but also allows the laser beam to pass through, reducing the thermal effect caused by the table surface reflecting or absorbing laser energy, and at the same time facilitating the falling and separation of waste materials during the processing.

[0033] The linear adjustment assembly 300 includes a support plate 301 symmetrically fixed to the upper side of the extension plate 202, a guide rail 302 fixed to the middle position of the upper side of the support plate 301, and a movable seat 304 that is movably engaged with the guide rail 302. The linear adjustment assembly 300 is used to adjust the working position of the subsequent clamping assembly 400. The clamping assembly 400 moves linearly with the movable seat 304 to meet the positioning requirements of different positions of the workpiece.

[0034] The clamping assembly 400 includes a mounting base 401 fixed to the upper end of the movable base 304, a pneumatic rod 402 movably embedded inside the mounting base 401, and a protective sleeve 404 fixed to the telescopic end of the pneumatic rod 402. The clamping assembly 400 is responsible for positioning and clamping the workpiece to be cut. Its pneumatic rod 402 serves as a driving source, and the workpiece is clamped and fixed by controlling the extension and retraction of its telescopic end. At the same time, a protective sleeve 404 is provided to increase friction and improve the stability of the workpiece.

[0035] Specifically, the mounting base 401 has a pair of through slots on its upper part, and a flip plate is movably disposed in the through slots. The main body of the air rod 402 is fixed to the upper side of the flip plate. The flip plate is connected to a rotary drive 403 via a shaft. The rotary drive 403 is fixed to the side of the mounting base 401. Multiple rotary drives 403 are independently controlled. The rotation angle range of the main body of the air rod 402 is 60°. Multiple air rods 402 are also independently controlled. The protective sleeve 404 is made of rubber and is clamped between the telescopic end of the air rod 402 and the workpiece. In this configuration, the rotary drive 403, the flipping plate, and the pneumatic rod 402 are arranged in a one-to-one correspondence to form a workpiece clamping unit. All four clamping units work independently, enabling the clamping assembly 400 to meet the positioning requirements of workpieces of different sizes. In a single clamping unit, the rotary drive 403 controls the rotation of the flipping plate to adjust the angle of the pneumatic rod 402. When the pneumatic rod 402 is in a horizontal state with the hollow table 201, it reaches the maximum upward rotation angle. The working angle of the pneumatic rod 402 determines whether its telescopic end is clamped or in contact with the workpiece for positioning.

[0036] Furthermore, a screw 303 is movably mounted on the upper end of the support plate 301. The screw 303 is equipped with a drive motor 305. The drive motor 305 is fixed to one side of the support plate 301. The screw 303 is threaded through the top of the movable seat 304. The drive motor 305 serves as the drive source for the screw 303, driving the rotation of the screw 303, thereby achieving linear drive of the movable seat 304.

[0037] The operation process in this embodiment is as follows:

[0038] Place the workpiece to be processed on the hollow table 201, ensuring that its position roughly matches the expected cutting path. Based on the size and shape of the workpiece, independently control the rotation drive 403 of each clamping unit to make the flip plate and air rod 402 reach a suitable angle to adapt to the surface contour of the workpiece. Adjust the angle of each air rod 402 by rotating the drive 403 to ensure that the protective sleeve 404 at the telescopic end of the air rod 402 can make good contact with the surface of the workpiece.

[0039] Start the drive motor 305, rotate the screw 303 to make the moving seat 304 move linearly along the guide rail 302, adjust the clamping assembly 400 to the optimal working position, ensure that all clamping units can be evenly distributed and firmly fix the workpiece, control the air rod 402 to perform the telescopic operation, so that the protective sleeve 404 fits tightly against the workpiece, and complete the positioning and clamping of the workpiece. At this time, pay attention to adjusting the telescopic force of the air rod 402 to avoid damage to the workpiece. After confirming that the workpiece has been firmly fixed, start the laser cutting process.

[0040] After cutting is completed, reverse the operation of the air rod 402 to retract it from the workpiece surface, release the clamping state on the workpiece, move the linear adjustment component 300 to move the clamping component 400 to a safe position, and then take out the cut workpiece.

[0041] Example 2

[0042] Please see Figure 1 Based on the first specific embodiment, the bottom of the support platform 200 is equipped with a movable frame 100. The movable frame 100 includes a pair of opposing supports 101, a support rod 103 fixed to the side of the support 101, and a drive rod 102 movably disposed in the middle of the support 101. The support rod 103 is movably inserted into the support seat 204. The drive rod 102 is threadedly fitted to the transmission seat 203, and the drive rod 102 is equipped with a drive motor 104. The drive motor 104 is embedded and fixed in the recess in the middle of the support 101. The movable frame 100 is used to support the support platform 200 and to adjust the position of the support platform 200. The drive motor 104, as the drive source, is responsible for driving the rotation of the drive rod 102, which acts on the hollowed-out platform 201 through the transmission seat 203 to realize the position adjustment of the hollowed-out platform 201.

[0043] The operation process in this embodiment is as follows:

[0044] Start the drive motor 104 to rotate the drive rod 102 and adjust the position of the support platform 200 to a height or position that is convenient for placing the workpiece. At this time, the support rod 103 moves within the support base 204 to ensure that the support platform 200 moves smoothly. Then, the operation steps in Embodiment 1 are executed.
