Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, and in particular to a laser cutting device with automatic adjustment effect. Background Art

[0002] Laser cutting uses a focused high-power density laser beam to irradiate the workpiece, causing the irradiated material to quickly melt, vaporize or reach the ignition point, and at the same time uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby achieving the cutting of the workpiece. It is one of the thermal cutting methods for cutting workpieces; the laser cutting machine is composed of multiple systems, including a laser generator, a light guide system, a motion system, a laser cutting head, a water source, and an air source. Among them, the laser cutting head is an important component, and the price of the laser cutting head is relatively expensive. Once damaged, the company will suffer huge losses.

[0058] Working principle: When the laser cutting machine body 3 and the laser cutting head 4 are working to cut the workpiece, the motor 3 504 is started. Under the action of the fixed rod 501, the output shaft of the motor 3 504 rotates to drive the shaft rod 502 to rotate. At this time, the rotating rod 503 rotates accordingly, forcing the protective cover 6 to rotate a certain angle. The protective covers 6 on both sides rotate outward, so that the laser cutting head 4 is exposed. At this time, the workpiece is located below the laser cutting head 4;

[0059] Start the electric push rod 701. Under the action of the tilting plate 702, the output end of the electric push rod 701 drives the connecting plate 8 to move to a reasonable position, forcing the connecting plate 8 to be horizontal. At this time, the cylinder 901 and the movable rod 903 face downward, and the roller 1105 contacts the workpiece.

[0060] When cutting, the laser cutting head 4 will move, and the motor 4 1202 will be started. The output shaft of the motor 4 1202 will rotate to drive the active bevel gear 1203 to rotate, so that the driven bevel gear 1204 will rotate. Under the action of the support rod 1101, the rotating shaft 1102 is forced to rotate, and the rotating shaft 1102 drives the mounting plate 1103 and the U-shaped block 1104 to rotate to a reasonable position. At the same time, the roller 1105 rotates, thereby ensuring that the roller 1105 follows the laser cutting head 4, so that the roller 1105 is in contact with the workpiece and ensures that the roller 1105 follows at a reasonable angle.

[0061] Since the roller 1105 rolls for a long time, when the roller 1105 needs to be repaired, the screw 1106 and the nut 1107 are rotated to force the U-shaped block 1104 to be separated from the mounting plate 1103, and the U-shaped block 1104 and the roller 1105 are disassembled to replace or repair the roller 1105; during installation, the U-shaped block 1104 is aligned with the mounting plate 1103, and the U-shaped block 1104 and the roller 1105 are installed on the mounting plate 1103 by using the screw 1106 and the nut 1107.

[0062] When roller 1105 contacts with the workpiece, the workpiece exerts a force on roller 1105, and the force is transmitted to baffle 904 through support rod 1101 and rotating shaft 1102. Baffle 904 exerts a force, spring 905 is compressed, and movable rod 903 drives piston 902 to move inside cylinder 901, forcing the hydraulic oil to be compressed. Through the action of oil guide pipe 1002, the hydraulic oil is compressed into storage cylinder 1001, thereby reducing kinetic energy. When a stable state is reached, the hydraulic oil will The hydraulic oil is introduced into the cylinder 901 through the oil guide pipe 1002. At this time, the hydraulic oil pushes the piston 902 to move, driving the movable rod 903 to move in the opposite direction, and the spring 905 slowly recovers. The movable rod 903 drives the baffle 904, the support rod 1101, the rotating shaft 1102, the mounting plate 1103 and the U-shaped block 1104 to recover to a balanced state. The roller 1105 contacts the workpiece and squeezes the two sides of the workpiece to prevent the workpiece from tilting and colliding with the laser cutting head 4. The cutting and squeezing effect on the thin plate is obvious, and the workpiece has a certain protective effect.

[0063] In the deployment scheme of the protective cover 6, the setting of the rotating mechanism 5 facilitates the deployment of the protective cover 6 to a reasonable angle, exposing the laser cutting head 4, improving the rationality of the device, and the protective cover 6 can block smoke; the setting of the pulling mechanism 7 can adjust the connecting plate 8 and the buffer mechanism 9 to a reasonable position, forcing the roller 1105 to contact the workpiece, forcing the buffer mechanism 9 and the roller 1105 to follow the operation of the laser cutting head 4, avoiding the workpiece from tilting, and reducing damage to the laser cutting head 4; the setting of the buffer mechanism 9 and the energy absorption mechanism 10 facilitates the buffer roller 1105 to absorb the instantaneous force of contact with the workpiece. Kinetic energy can effectively reduce the reaction force of roller 1105 on the workpiece, which is beneficial to protecting the workpiece, improving the quality of the workpiece, and improving the protection ability of the equipment; that is, the setting of the pressing component 11 can force the roller 1105 to follow the movement of the laser cutting head 4 when the laser cutting head 4 cuts the workpiece, thereby avoiding the workpiece from tilting and further protecting the laser cutting head 4. The setting of the driving component 12 is convenient for forcing the roller 1105 to follow the movement, ensuring that the roller 1105 and the laser cutting head 4 are in the same direction of movement, reducing resistance, facilitating the smooth operation of the laser cutting head 4, and improving the rationality and stability of the device.

[0064] When the laser cutting head 4 is not working, the motor 3 504 is started. Under the action of the fixed rod 501, the output shaft of the spot inspection rotates to drive the shaft rod 502 to rotate. At this time, the rotating rod 503 rotates to the original position, forcing the protective cover 6 to rotate inwardly by an angle, so that the two protective covers 6 are closed, covering the laser cutting head 4, isolating the laser cutting head 4 from the outside, and improving the protection ability of the laser cutting head 4;

[0065] Start the electric push rod 701. Under the action of the tilting plate 702, the output end of the electric push rod 701 drives the connecting plate 8 to move to a reasonable position, forcing the connecting plate 8 to be in a vertical state. At this time, the cylinder 901 and the movable rod 903 face both sides, and the roller 1105 faces outward;

[0066] When an external object collides, the object will collide with the roller 1105, generating a force on the roller 1105, and transmitting the force to the baffle 904 through the support rod 1101 and the rotating shaft 1102. The baffle 904 generates a force, the spring 905 is compressed, and the movable rod 903 drives the piston 902 to move inside the cylinder 901, forcing the hydraulic oil to be compressed. Through the action of the oil guide pipe 1002, the hydraulic oil is compressed into the storage cylinder 1001, thereby reducing the kinetic energy of the impact force; when a stable state is reached, the hydraulic oil will The hydraulic oil is introduced into the cylinder 901 through the oil guide pipe 1002. At this time, the hydraulic oil pushes the piston 902 to move, driving the movable rod 903 to move in the opposite direction, and the spring 905 slowly recovers. The movable rod 903 drives the baffle 904, the support rod 1101, the rotating shaft 1102, the mounting plate 1103 and the U-shaped block 1104 to recover to a balanced state. When the impact force is transmitted to the protective cover 6, it has been greatly reduced, thereby reducing the damage to the protective cover 6, which is beneficial to protecting the protective cover 6, further protecting the laser cutting head 4, and improving the buffering effect of the equipment;

[0067] In the closing scheme of the protective cover 6, the setting of the rotating mechanism 5 is convenient for closing the protective cover 6 and surrounding the laser cutting head 4, thereby improving the rationality of the device, and the protective cover 6 can effectively block external collisions; the setting of the pulling mechanism 7 is convenient for adjusting the connecting plate 8 and the buffer mechanism 9 to a reasonable position, so that the device can protect the protective cover 6 when a collision occurs; the setting of the buffer mechanism 9 and the energy absorption mechanism 10 greatly reduces the external impact kinetic energy during a collision, effectively reduces the impact of the force on the protective cover 6 and the laser cutting head 4, further effectively protects the laser cutting head 4, and improves the self-protection ability and anti-collision ability of the equipment; the setting of the pressing component 11 is in direct contact with external objects, reducing the possibility of direct contact between the object and the protective cover 6 and the laser cutting head 4, effectively protecting the protective cover 6 and the laser cutting head 4, and improving the rationality of the device;

[0068] Since the roller 1105 is in direct contact with external objects, when the roller 1105 needs to be repaired, the screw 1106 and the nut 1107 are rotated to force the U-shaped block 1104 to separate from the mounting plate 1103, and the U-shaped block 1104 and the roller 1105 are removed to replace or repair the roller 1105. The setting of the screw 1106 and the nut 1107 facilitates the replacement of the U-shaped block 1104, the disassembly and installation of the U-shaped block 1104 and the roller 1105, and facilitates the operation of the staff.
