[0002] Laser cutting is the process of cutting materials with lasers. It can quickly cut according to different shapes and is widely used in machinery, hardware, parts and other fields. The laser cutting process is to guide the laser beam to the surface of the processed material to form a cutting gap. The laser beam heats the material in the cutting gap, causing the material to melt or vaporize, and finally the melted or vaporized material is blown away by the airflow, thereby achieving cutting.

[0003] In the prior art, Chinese patent publication number CN213864324U discloses a laser blanking and clamping device for metal sheets, comprising a base plate, support plates symmetrically fixedly connected to the left and right sides of the top of the base plate, and a plurality of adjustment blocks, adjustment screws fixedly connected between the support plates, and a plurality of adjustment nuts screwedly connected to the circumferential outer wall of the adjustment screw, and each adjustment block is provided with an adjustment through hole running through the left and right sides.

[0004] In the existing laser blanking mechanism, before cutting the material, the personnel place the material directly on the table and rely on the material's own weight to fix it. If the material is light, the airflow will blow the plate, causing the position of the plate to shift and affecting the cutting accuracy of the plate. Based on this, we proposed a laser blanking clamping tooling. Utility Model Content

[0025] The following is a detailed description of the present invention, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. 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] like Figure 1 - Figure 5As shown, a laser blanking clamping tool includes a base plate 1 and a plurality of mounting slots 2. The mounting slots 2 are provided on the top surface of the base plate 1 and are arranged in a circular array. The inner wall of the mounting slot 2 is fixedly connected to a mounting plate 3.

[0027] A clamping assembly, the clamping assembly is located above the mounting plate 3;

[0028] The adjusting component is located above the mounting plate 3 and is used to adjust the clamping component.

[0029] Furthermore, the clamping assembly includes a clamping block 4 and a tension spring 9. The clamping block 4 is located above the mounting plate 3. A clearance groove 5 is opened on one side of the clamping block 4. First rotating holes 6 are opened on both sides of the inner wall of the clearance groove 5. The inner walls of the two first rotating holes 6 are rotatably connected to the same rotating shaft 7. The circumferential side of the rotating shaft 7 is rotatably connected to a connecting block 8. The tension spring 9 is connected to the bottom surface of the connecting block 8. A placement groove 10 is opened at the top of the mounting plate 3. The bottom end of the tension spring 9 is fixedly connected to the inner bottom surface of the placement groove 10.

[0030] Furthermore, the adjustment assembly includes a screw rod 12 and a handle 13. The top end of the screw rod 12 is fixedly connected to the bottom end of the handle 13. A rotation groove 11 is provided on the top surface of the mounting plate 3. The screw rod 12 is rotationally connected to the rotation groove 11. The circumferential side of the screw rod 12 is slidingly connected to a first slider 14. Second rotation holes 15 are provided on both sides of the inner wall of the give way groove 5. The inner walls of the two second rotation holes 15 are rotationally connected to the circumferential side of the same first slider 14.

[0031] Furthermore, both ends of the first slider 14 are rotatably connected to the second slider 16, and the top surface of the mounting plate 3 is fixedly connected to two sliding columns 17. The two sliding columns 17 are symmetrically arranged, and a sliding groove 18 is provided on the side of the sliding column 17 close to the clamping block 4. The second slider 16 is slidably connected to the inner wall of the sliding groove 18.

[0032] Furthermore, the clamping block 4 is of a special shape, which is convenient for clamping and fixing materials of different thicknesses when rotated to different angles. One end of the clamping block 4 is arc-shaped, and one end of the clamping block 4 is against the top surface of the mounting plate 3.

[0033] Furthermore, the width of the rotating shaft 7 is greater than the width of the connecting block 8, and the peripheral side of the rotating shaft 7 is a smooth plane so that the connecting block 8 can rotate around the rotating shaft 7, so that when a person presses the connecting block 8, the surface where the connecting block 8 is fixedly connected to the tension spring 9 always remains facing downward, avoiding excessive stretching that causes the tension spring 9 to bend.

[0034] Working principle: When a person wants to fix the material, he first turns the handle 13. At this time, the handle 13 drives the screw rod 12 to rotate. The rotation of the screw rod 12 drives the first slider 14 to move upward. The upward movement of the first slider 14 drives the clamping block 4 to move upward. The first slider 14 drives the two second sliders 16 to slide upward in the corresponding sliding groove 18. At this time, the other end of the clamping block 4 drives the rotating shaft 7 to move upward. The rotating shaft 7 drives the connecting block 8 to move upward, thereby stretching the tension spring 9 upward. At this time, the person presses the connecting block 8, so that the connecting block 8 drives the clamping block 4 around the first slider 14 through the rotating shaft 7. A slider 14 rotates, and at this time the connecting block 8 squeezes the tension spring 9 downward, and the end of the clamping block 4 away from the rotating shaft 7 is lifted up around the first slider 14 as the axis. The person places the material under this end of the clamping block 4 and releases the connecting block 8. At this time, the tension spring 9 rebounds and drives the connecting block 8 to move upward. The upward movement of the connecting block 8 drives the rotating shaft 7 to move upward. The rotating shaft 7 drives the end of the clamping block 4 close to the rotating shaft 7 to lift up around the first slider 14 as the axis. At this time, the other end of the clamping block 4 rotates downward to clamp and position the material to prevent the airflow from blowing up the material and affecting the cutting effect during the cutting process.

[0035] The above description is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
