Description

Technical Field

[0001] This utility model relates to the technical field of laser cutting machines, specifically a dynamic adjustment device for laser beam size. Background Technology

[0002] A laser cutting machine uses a laser beam emitted from a laser source. The laser beam is focused into a high-power-density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a kerf is eventually formed in the material, thus achieving the purpose of cutting. Therefore, the effect of laser cutting is related to the size of the laser beam.

[0003] The existing laser cutting machine requires changing different lasers to adjust the laser beam, which is very inconvenient. In addition, when changing and adjusting different laser beams, dust will adhere to the laser's focusing lens, affecting the laser cutting effect. Therefore, we propose a dynamic laser beam size adjustment device to solve the problems mentioned above. Utility Model Content

[0021] Please see Figure 1-5 This utility model provides a technical solution: a dynamic adjustment device for laser beam size, including a housing 1, a laser head 4, an adjustment gear 13, and a mounting block 18. An inlet 2 is provided on the upper part of the housing 1, and an adjustment plate 3 is provided on the lower part of the housing 1. Laser heads 4 are evenly installed on the lower part of the adjustment plate 3, and a beam-aligning port 5 is provided on the upper part of the laser head 4 corresponding to the position of the adjustment plate 3. The beam apertures of the laser heads 4 below the adjustment plate 3 decrease in size from left to right. The second alignment line 7 on the surface of the adjustment plate 3 corresponds one-to-one with the beam-aligning port 5 on the upper part of the laser head 4, which facilitates the docking of laser heads 4 with different beams with the housing 1 under the sliding action of the adjustment plate 3, and facilitates the adjustment of laser heads 4 with different beams. A first alignment line 6 is provided in the middle of the housing 1, and a second alignment line 7 is provided on the side of the adjustment plate 3. The adjustment plate 3 is U-shaped. The adjustment plate 3 is connected to the slots 22 on both sides of the housing 1 by the locking blocks 8 at both ends of the inner side to form a locking sliding connection, which facilitates the sliding of the adjustment plate 3 under the housing 1.

[0022] Please see Figure 1-5A locking block 8 is fixed to the inner side of the adjusting plate 3. Toothed blocks 9 are evenly installed on the upper surface of the locking block 8. Cleaning sponges 10 are glued to both ends of the lower part of the casing 1. An inner cavity 11 is opened at both the front and rear ends of one side of the casing 1, and a rotating shaft 12 is rotatably connected to the inner cavity 11. Adjusting gears 13 are fixed to both ends of the rotating shaft 12. The toothed blocks 9 on the surface of the locking block 8 and the adjusting gears 13 inside the inner cavity 11 form a meshing connection, allowing the adjusting gears 13 to be rotated. The gear 8 engages with the toothed block 9 above the locking block 8, allowing the locking block 8 to drive the adjusting plate 3 to slide at the bottom of the housing 1. Fixed sleeves 14 are fixed to both ends of the side of the housing 1, and limit rods 15 are connected to the fixed sleeves 14. The limit rods 15 are slidably connected to the fixed sleeves 14. Two sets of limit rods 15 are provided, and the side blocks 16 at the ends of the two sets of limit rods 15 are connected by springs 17. The ends of the limit rods 15 are engaged with the adjusting gear 13, facilitating the movement of the limit rods 15. The fixed sleeve 14 slides to allow the limiting rod 15 to move to both ends and engage with the adjusting gear 13, facilitating the positioning of the adjusting gear 13 after rotation. Simultaneously, the spring 17 between the side blocks 16 facilitates the reset of the limiting rod 15 after sliding. The inner end of the limiting rod 15 is fixed with a side block 16. A mounting block 18 is fixed above the middle of the housing 1, and an adjusting screw 19 is rotatably connected to the surface of the mounting block 18.

[0023] Working principle: First, when in use, the device is connected to the laser cutting machine. When the laser beam needs to be adjusted, the adjusting gear 13 can be rotated to drive the toothed block 9 above the lower locking block 8 to engage and transmit the transmission, so that the adjusting plate 3 can slide on the machine housing 1. During adjustment, the second alignment line 7 on the surface of the adjusting plate 3 can be aligned with the first alignment line 6 in the middle of the machine housing 1 to facilitate the adjustment of different laser head 4 beams. After adjustment, the adjusting screw 19 can be rotated to make the adjusting screw 19 and the limiting block 20 move threadedly, so that the limiting block 20 can move threadedly downward on the side of the machine housing 1, so that the limiting block 20 can be engaged between the inner side blocks 16 of the two sets of limiting rods 15 to slide, so that the limiting rods 15 can move to both ends, so that the limiting rods 15 can be engaged on the adjusting gear 13, so that the adjusting gear 13 can be positioned after rotation.

[0024] The housing 1 has cleaning sponges 10 attached to both ends at the bottom. When replacing the laser head 4, it is convenient to clean the dirt on the lens of the light-adjusting port 5 above the adjustment plate 3, which facilitates the cleaning of the upper light-adjusting port 5 and improves the use effect of replacing the laser head 4. This is the working principle of the dynamic adjustment device for laser beam size.
