Abstract
The utility model relates to a light portal frame structure. The light portal frame structure comprises a left guide rail assembly and a right guide rail assembly which are arranged horizontally in parallel, each guide rail assembly is provided with an end beam, and a cross beam is connected between the end beams. The light portal frame structure is characterized in that each guide rail assembly comprises a I-shaped steel, the corresponding end beam is arranged at the top of the I-shaped steel, the lower end of the end beam is provided with a fixing shaft, the end portion of the fixing shaft is provided with a wheel, and the circumferential surface of the wheel is tangent to the upper end surface of the I-shaped steel; each end beam is provided with a clamping device, the clamping device comprises bearings mounted on both sides of the I-shaped steel, and he bearings are fixed to the end beam through guide shafts and nuts; the guide shafts on both sides of the I-shaped steel are composed of a linear guide shaft and an eccentric guide shaft. The light portal frame structure is reasonable in structure, stable in precision, reliable in performance, accurate in positioning and applicable to various severe environments, has sufficient rigidity, avoids deformation and torsion due to long-time reciprocating movement, greatly improves the product production efficiency and guarantees product quality.
Description
Technical field
The utility model relates to a kind of light gantry structure, especially a kind of gantry structure for numerical control cutting machine.
Background technology
Planer type numerical control flame/plasma/vertical bar cutting machine adopts bilateral exchange servo-drive mode, is the heat-cutting machine equipment of a kind of high efficiency, high accuracy, high reliability.Numerical control cutting machine is divided into two kinds of planer-type and cantilevereds by version.Numerical-controlled gantry cutting machine adopts gantry structure support works main frame to move horizontally, structural stability is high, solid, durable, adopt the mode of bilateral driving to operate steadily, move accurately, crudy is good, precision is high, uses more in the work processing of large-scale production and hi-precision cutting requirement.The gantry structure of numerical control cutting machine, in order to guarantee cut quality and cutting accuracy, is had relatively high expectations to user installation now, has increased difficulty to actual installation process, also easily causes installation accuracy to affect not crudy.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of light gantry structure, rational in infrastructure, stable accuracy.
The technical scheme providing according to the utility model, a kind of light gantry structure, comprises that left and right is parallel to the guide assembly arranging, and on the guide assembly of two groups of left and right, end carriage is set respectively, connecting cross beam between the end carriage of the left and right sides; Feature is: described guide assembly comprises I-steel, and end carriage is positioned at the top of I-steel, and fixed axis is installed in end carriage lower end, and the end of fixed axis arranges roller, and the periphery of roller and the upper surface of I-steel are tangent; On described end carriage, clamping device is installed, clamping device comprises the bearing that is arranged on I-steel both sides, and bearing is fixed by the axis of guide and nut and end carriage respectively.
The axis of guide of described I-steel both sides is respectively straight-line guidance axle and the eccentric axis of guide.
On described crossbeam, arrange and can, along the moving body of cross beam movement, welding gun be installed on moving body.
Compared with the prior art the utility model has the following advantages: the utility model is rational in infrastructure, stable accuracy, dependable performance, registration, can adapt to various adverse circumstances, there are enough rigidity, can, because moving back and forth and deform and twisted phenomena for a long time, greatly not improve the production efficiency of product and guarantee product quality.
Accompanying drawing explanation
