The demand for improved production efficiency, reduced production costs, and highly intelligent automated cutting functions is also increasing. Laser cutting machines offer high precision, fast cutting speeds, unlimited cutting patterns, automatic layout saving of materials, and smooth cuts. However, laser cutting machines are expensive and costly, making them suitable for thin sheet metal cutting and applications requiring high precision. During laser cutting, the laser gas can move the workpiece, resulting in uneven cutting. Therefore, a clamping device is required to secure the workpiece. Utility Model Content

[0003] In order to overcome the defects in the prior art, the utility model provides a clamping device for laser cutting. When using laser cutting materials, the device is used to clamp the material to be cut to prevent the material to be cut from shaking, thereby avoiding uneven cutting. The clamping device of the device can slide along the guide rail to facilitate the adjustment of the position of the material, making the cutting process more flexible.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a clamping device for laser cutting, comprising:

[0005] A guide rail, wherein the guide rail is provided with a slider, and the slider can slide back and forth along the guide rail;

[0006] The clamping device includes a first clamping plate, the first clamping plate is fixedly connected to the slider, and a second clamping plate is arranged opposite to the first clamping plate. The second clamping plate is connected to a driving member, and the driving member can drive the second clamping plate to move toward or away from the first clamping plate.

[0007] With the above solution, when using laser cutting, the clamping device is used to clamp the material between the first clamping plate and the second clamping plate to fix the material, preventing the material from shaking during cutting, thereby preventing uneven cutting. Moreover, because the slider can slide along the guide rail with the clamping device, the position of the material can be easily adjusted as needed.

[0008] Furthermore, it comprises at least two parallel guide rails, and the two ends of the first clamping plate are respectively connected to the sliders on the two guide rails. In the present application, guide rails are provided at both ends of the clamping device to ensure the stability of the clamping device.

[0009] Furthermore, it includes at least two clamping devices arranged in parallel, and the material to be cut is clamped between the clamping devices. The present application provides two clamping devices, and the material is clamped between the two clamping devices, so that the gravity of the material is distributed on the two clamping devices, which increases the weighing capacity of the clamping devices and increases the stability during clamping.

[0010] Furthermore, the slider is connected to a first connecting member;

[0011] The driving member includes a cylinder, which is fixedly connected to the first connecting member, and the driving end of the cylinder is connected to the second clamping plate. With the above solution, the material is placed between the first clamping plate and the second clamping plate, and the cylinder drives the second clamping plate to move toward the first clamping plate, thereby clamping and fixing the material.

[0012] Furthermore, the first clamping plate is provided with a guide rod extending toward the second clamping plate, the second clamping plate is provided with a guide hole, and the guide rod passes through the guide hole. The guide rod limits the movement direction of the second clamping plate to ensure stable clamping of the workpiece.

[0013] Furthermore, the guide rail includes a screw, and the slider is threadedly connected to the screw. Rotating the screw can adjust the position of the slider and the clamping device. Each screw is connected to the same drive device, and the same drive device controls the rotation of the screw to ensure that the movement of each clamping device is synchronized, thereby preventing the material from being torn due to asynchronous movement of the screws.

[0014] Furthermore, the two sliders can move toward or away from each other as the screw rod rotates.

[0015] Furthermore, the clamping device is detachably connected to the slider, and the relative position of the slider with respect to the screw rod can be adjusted by rotating the slider alone.

[0016] Furthermore, the first and second clamping plates are both provided with rubber strips on opposite sides, and the material to be cut is clamped between the two rubber strips. The rubber strips have a certain elasticity and can provide a buffering and protective function for the material.

[0017] By means of the above technical solution, the beneficial effects of the present invention are as follows:

[0018] 1. In this application, by connecting the clamping device to the slider of the guide rail, the clamping device can move along the guide rail with the material to be cut according to the cutting requirements, making the cutting process more flexible;

[0019] 2. In the present application, the interval between the sliders on the same screw rod is adjustable, so that the spacing between the clamping devices can be adjusted in real time according to the size of the material to be cut, and the adaptability is high.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] It should be noted that, in the description of this utility model, the terms "first," "second," etc., are used solely for descriptive purposes and to distinguish similar objects. There is no order of precedence between the two, nor should they be construed as indicating or implying relative importance. Furthermore, in the description of this utility model, unless otherwise specified, "plurality" means two or more.

[0027] Example: Combination Figure 1-2 As shown, this embodiment discloses a clamping device for laser cutting, comprising:

[0028] Two threaded screws 1 are arranged in parallel, and two screw nuts are sleeved on each of the threaded screws 1. The two screw nuts move toward or away from each other under the drive of the threaded screws 1. A second connecting member 11 is provided on the outside of the screw nut. In this embodiment, the second connecting member 11 is square, and a first step is provided on the upper side of the second connecting member 11. A connecting plate 12 is connected to the first step, and connecting holes are provided on the four corners of the connecting plate 12. A first threaded hole that matches the connecting hole is provided on the first step of the second connecting member 11. The connecting plate 12 can be fixedly connected to the second connecting member 11 by passing a screw through the connecting hole and screwing it into the first threaded hole. Wherein, the two threaded screws 1 are connected to the same motor.

[0029] The side of the connecting plate 12 facing away from the second connecting member 11 is connected to a clamping device, and the clamping device includes a first clamping plate 21 connected to the connecting plate 12, and the two ends of the first clamping plate 21 are respectively provided with a second step, and the second step is provided with a second threaded hole that matches the connecting hole of the connecting plate 12. The first clamping plate 21 can be fixedly connected to the connecting plate 12 by passing a screw through the connecting hole and screwing into the second threaded hole. The two ends of the first clamping plate 21 are respectively connected to the second connecting member 11 on the two threaded screws 1. Compared with only providing the threaded screw 1 at one end of the first clamping plate 21, the first clamping plate 21 may bend at the connection point between itself and the threaded screw 1 due to excessive weight. The present application provides threaded screws 1 at both ends of the first clamping plate 21, so that both ends are supported to ensure the stability of the clamping device.

[0030] Guide rods 211 extending perpendicularly to the first clamping plate 21 are provided on the underside of the first clamping plate 21 near both ends. A second clamping plate 22 is provided below the first clamping plate 21. The second clamping plate 22 has guide holes that fit into the guide rods 211, through which the guide rods 211 pass. In other words, the second clamping plate 22 can move perpendicularly toward or away from the first clamping plate 21 along the guide rods 211.

[0031] like Figure 1 As shown, two parallel clamping devices are provided between the two threaded screws 1. Under the traction of the second connecting member 11, the two clamping devices can move toward or away from each other along the threaded screw 1 along with the screw nut. In other words, the threaded screw 1 can adjust the spacing between the two clamping devices. This solution enables the laser cutting clamping device to adapt to various sizes of materials and various cutting requirements.

[0032] Optionally, a linear bearing is provided in the guide hole of the second clamping plate 22, and the linear bearing is sleeved on the guide rod 211. The provision of the linear bearing can reduce the friction between the second clamping plate 22 and the guide rod 211, thereby increasing the service life of the second clamping plate 22 and the first clamping plate 21.

[0033] Optionally, the first and second splints 21 and 22 are provided with elastic adhesive strips 23 on opposite sides. The workpiece 3 to be cut is clamped between the adhesive strips of the first and second splints 21 and 22, providing a buffering protection function to prevent the workpiece from being damaged by the hard splints.

[0034] A cylinder 221 is connected to the underside of the second clamping plate 22. The cylinder 221 is used to drive the second clamping plate 22 to move toward or away from the first clamping plate 21, thereby clamping or releasing the workpiece 3 to be cut. The cylinder body of the cylinder 221 is fixed to the connecting block 13, and the connecting block 13 is fixedly connected to the second connecting member 11 by bolts.

[0035] With the above solution, when laser cutting a workpiece, the clamping device is used to clamp the workpiece between the first clamping plate 21 and the second clamping plate 22 to secure the workpiece 3 to be cut, preventing the workpiece from shaking during cutting and thus preventing uneven cutting. Furthermore, because the second connecting member 11 can slide along the guide rail 1 with the clamping device, the position of the workpiece can be easily adjusted as needed.

[0036] When using the above-mentioned clamping device for laser cutting, the workpiece 3 to be cut is manually placed on the two second clamping plates 22, so that the area to be cut is between the two clamping devices. The cylinder 221 drives the second clamping plate 22 to move toward the first clamping plate 21 to clamp and fix the workpiece 3 to be cut. The motor drives the screw rod 1 to rotate, transferring the workpiece to a preset position for cutting by the laser cutting machine. It should be noted that during the cutting process, the motor can drive the screw rod 1 to rotate to adjust the position of the workpiece 3 to be cut in real time to meet the cutting requirements.

[0037] Since the connecting plate 12 and the second connecting member 11 are detachably connected, the clamping device can be removed from the second connecting member 11, so that the initial positions of the two second connecting members 11 on the same threaded screw 1 can be adjusted to adapt to different cutting requirements.

[0038] The present invention uses specific embodiments to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
