Description

TECHNICAL FIELD

[0001] The utility model relates to a crossbeam structure applied to a portal bed body. BACKGROUND

[0002] At present, with the continuous improvement of the power of the laser, the cuttable material thickness of the laser cutting machine also increases, so that it more and more pursues large-scale processing, which brings new challenges to the crossbeam structure, and the crossbeam structure has to develop in the direction of lightweight, long span, high rigidity, etc. The laser cutting machine with small amplitude usually adopts cast aluminum structure and profile extrusion structure, etc. When the amplitude increases, the rigidity of the material itself will decrease obviously.

[0003] The laser cutting machine with large amplitude usually adopts carbon steel plate welding structure. Although the selection of carbon steel welding can increase the rigidity of the crossbeam, the weight will also increase obviously, so a larger driving motor power is needed. In view of the above technical problems, the crossbeam structure applied to the portal bed body designed by the patent adopts carbon steel plate welding, reduces the overall weight in structure, and considers rigidity and long span at the same time.

[0006] Further, the upper side plate and the lower side plate are both made of carbon steel.

[0007] Further, the upper side plate, the lower side plate, the left side plate, the right side plate, the front component and the rear component are fixedly connected by welding.

[0008] Further, the support plate is connected in the crossbeam main part by welding.

[0009] Further, the crossbeam main part is provided with a motor seat on both sides in front.

[0010] Further, the left side plate and the right side plate are both provided with through holes.

[0011] Beneficial effects: compared with the prior art, the whole adopts carbon steel plate welding structure, replaces the cast aluminum beam structure of small amplitude laser cutting machine, ensures the overall rigidity of the beam in the application process of long span laser cutting machine, internally welds multiple groups of supporting plates, and the supporting plates are in a back-shaped structure, thereby reducing the overall weight of the beam, improving the bending resistance of the beam, and realizing the long span application of the beam.
