[0002] Laser cutting machine is a machine that uses laser technology to cut materials. It irradiates the surface of the material with a high-energy laser beam, uses the high energy of the laser to quickly melt, vaporize or ignite the material, and blows away the melted or burned residue with a high-speed airflow, thereby achieving the purpose of cutting.

Once the laser cutting machine is hit by external impact, the probability of its failure will increase. Therefore, the use of anti-collision devices is essential for laser cutting machines. However, in factories, the continuous deployment of anti-collision devices will have certain requirements for site occupation. In some small enterprises, when the laser cutting machine is not in use, occupying too much space will cause interference to the surrounding staff. Hereby, a laser cutting machine anti-collision device is proposed. Utility Model Content

[0023] Reference Figure 1-4, a laser cutting machine anti-collision device comprises a laser cutting machine body 1, both sides of the laser cutting machine body 1 are fixedly connected with vertical plates 2, one side of the vertical plate 2 is provided with an installation groove 6, the inner cavity of the installation groove 6 is horizontally provided with a rectangular slide bar 9, both sides of the outer ring of the rectangular slide bar 9 are sleeved with sliding blocks 10, one side of the vertical plate 2 is provided with a steel leaf spring 11, the two ends of the steel leaf spring 11 are respectively fixedly connected with one side of the adjacent sliding block 10, a bidirectional screw rod 4 is horizontally provided on one side of the rectangular slide rod 9, both sides of the outer ring of the bidirectional screw rod 4 are sleeved with screw sleeves 5, and the outer ring of the rectangular slide rod 9 and one side of the screw sleeve 5 are sleeved with a sliding sleeve 8. Specifically, when personnel use it, the personnel can adjust the curvature of the steel leaf spring 11 on both sides of the laser cutting machine body 1 according to the actual use scenario. When the laser cutting machine body 1 is in use, the personnel can drive the motor 3 to rotate the bidirectional screw rod 4, and the screw sleeves on both sides of the outer ring of the bidirectional screw rod 4 The sleeve 5 will drive the corresponding sliding sleeve 8 to squeeze the adjacent sliding block 10, so that the two sliding blocks 10 squeeze the corresponding leaf spring 11, so that the curvature of the leaf spring 11 increases, thereby improving the anti-collision coefficient on both sides of the laser cutting machine body 1, providing stable protection for both sides of the laser cutting machine body 1 and also serving as a warning during the operation of the device. When the laser cutting machine body 1 stops running, the motor 3 drives the bidirectional screw 4 to reverse, and the sliding block 10 is driven to restore its initial position by the elastic force of the leaf spring 11 itself, so that the leaf spring 11 is hidden in the corresponding installation groove 6. Through the structural design, personnel can start the anti-collision device in time during the startup of the laser cutting machine body 1, thereby ensuring the stable operation of the laser cutting machine body 1, preventing the damage to the internal electronic components of the laser cutting machine body 1 caused by the collision of foreign objects, and protecting the property of personnel.

[0024] This program has the following working process:

[0025] When in use, the personnel can adjust the curvature of the leaf springs 11 on both sides of the laser cutting machine body 1 according to the actual usage scenario. When the laser cutting machine body 1 is in use, the personnel can drive the bidirectional lead screw 4 to rotate by the motor 3, and the screw sleeves 5 on both sides of the outer ring of the bidirectional lead screw 4 will drive the corresponding sliding sleeves 8 to squeeze the adjacent sliding blocks 10, so that the two sliding blocks 10 squeeze the corresponding leaf springs 11, so that the curvature of the leaf spring 11 increases, thereby improving the anti-collision coefficient on both sides of the laser cutting machine body 1, providing stable protection for both sides of the laser cutting machine body 1, and also serving as a warning during the operation of the device. When the laser cutting machine body 1 stops running, the motor 3 drives the bidirectional lead screw 4 to reverse, and the sliding block 10 is driven to restore to its initial position by the elastic force of the leaf spring 11 itself, so that the leaf spring 11 is hidden inside the corresponding mounting groove 6.

[0032] Furthermore, one end of the sliding sleeve 8 abuts against one end of the adjacent sliding block 10, and the height of the leaf spring 11 matches the inner cavity of the corresponding mounting groove 6. Specifically, through the setting of the bidirectional screw rod 4, personnel can control the positional relationship of the two screw sleeves 5 at the same time.

[0033] To sum up: when personnel are in use, they can adjust the curvature of the leaf springs 11 on both sides of the laser cutting machine body 1 according to the actual usage scenario. When the laser cutting machine body 1 is in use, the personnel can drive the bidirectional lead screw 4 to rotate through the motor 3, and the screw sleeves 5 on both sides of the outer ring of the bidirectional lead screw 4 will drive the corresponding sliding sleeves 8 to squeeze the adjacent sliding blocks 10, so that the two sliding blocks 10 squeeze the corresponding leaf springs 11, so that the curvature of the leaf spring 11 increases, thereby improving the anti-collision coefficient on both sides of the laser cutting machine body 1, providing stable protection for both sides of the laser cutting machine body 1, and also serving as a warning during the operation of the device.
