The invention relates to a light rail device for a light gantry numerical control cutting machine. The light rail device comprises left and right guide rail assemblies which are parallelly symmetrical, and the light rail device is characterized in that each guide rail assembly comprises I-shaped steel, a plurality of guide rail base plates are fixed on the I-shaped steel along the length direction of the I-shaped steel and connected with one another through light rails, the light rails are placed on upper surfaces of the guide rail base plates, guide rail pressing plates are arranged on two sides of each guide rail base plate, one end of each guide rail pressing plate and the guide rail base plates are fixed through second bolts, the other end of each guide rail pressing plate presses lower ends of the light rails and fixed through third bolts, end beams are arranged above the light rails, rollers and clamping devices are installed at two ends of the end beam respectively, the circumference face of each roller is tangent to upper end faces of the light rails, the clamping devices comprise bearings on two sides of light rails, and the bearings and the end beams are fixed through guide shafts and second nuts. The light rail device has both stability and rigidity and is good in guidance quality, stable, durable, and applicable to various severe environments.
Description
technical field [0001] The invention relates to a light rail, in particular to a light rail device used on a light gantry numerical control cutting machine, and belongs to the technical field of mechanical structures. Background technique [0002] In the prior art, the single-axis core guide rail has been widely used in the guiding field of light-duty gantry type CNC cutting machine, and it shows excellent linear guide performance in the linear guide rail. However, for light-duty gantry-type CNC cutting machines, which have repetitive mobility, after a long period of reciprocating motion, the single-axis core guide rails will be deformed and twisted. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a light rail device for light gantry CNC cutting machines, which has both stability and rigidity, good guiding and durability, and can adapt to various harsh environments without Deformation and...
