Description

Technical Field

[0001] The utility model relates to the field of laser technology, in particular to a laser cutting machine with dust removal effect. Background Art

[0002] With the continuous advancement of industrial technology, laser cutting, as a high-precision and high-efficiency cutting method, has been widely used in many fields. Laser cutting uses a high-energy-density laser beam to irradiate the workpiece, causing the material to melt, vaporize or reach the ignition point instantly, and at the same time uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby achieving the purpose of cutting the material.

[0003] In the laser cutting process, the fixation of the material is very important. If the material moves or shakes during the cutting process, it will directly affect the cutting accuracy, causing the size deviation of the cut product to be large and unable to meet the high-precision production requirements. Laser cutting generates a lot of heat, causing the material to heat up locally. If there is no good fixture fixation, the material is more likely to deform after being heated, further reducing the cutting accuracy. Utility Model Content

[0004] The utility model aims to solve the problems in the background technology and proposes a laser cutting machine with dust removal effect.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The fixing mechanism includes two support frames fixedly connected to the top of the base, the two support frames are fixedly connected to the top of a support ring, the support ring passes through and is rotatably connected to a plurality of rotating sleeves, the rotating sleeve is threadedly connected to a first threaded rod, the rotating sleeve is fixedly connected to the first gear at one end away from the first threaded rod, the support frame passes through and is rotatably connected to a gear ring, the gear ring is meshed with the first gear, and the first threaded rod is fixedly connected to the end away from the rotating sleeve.

[0008] Preferably, a first motor is fixedly mounted on the side wall of the support frame, a second gear is fixedly connected to the output end of the first motor, the second gear is meshed with a gear ring, and a plurality of first sliding rods are penetrated and slidably connected to the support ring.

[0009] Preferably, two support rods are fixedly connected to the top of the base, and a second threaded rod is passed through and rotatably connected to the upper side wall of the support rod. A laser generator is sleeved on and threadedly connected to the second threaded rod, and a cutting head is installed on the top of the laser generator.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model can apply clamping force to the material evenly from multiple directions by setting a fixing mechanism to ensure that the material will not move or shake during the cutting process. This is crucial for high-precision laser cutting and can effectively improve the cutting accuracy and quality, making the cutting edge smoother and the size more accurate. A large amount of heat will be generated during the laser cutting process, which may cause thermal deformation of the material. A good clamp can limit the deformation of the material, reduce the dimensional deviation and shape change caused by thermal deformation, and improve the stability of processing.

[0015] 2. The utility model has a larger dust suction area by setting two dust suction ports. Setting two dust suction ports next to the cutting head can cover the cutting area more widely, ensuring that the smoke and dust generated during the laser cutting process can be quickly and effectively sucked away. Due to the increase in the dust suction area, the dust suction port can suck more smoke and dust per unit time, which helps to improve the dust removal efficiency of the laser cutting machine and reduce the spread of smoke and dust in the working environment.
