Abstract

The invention relates to a lightweight gantry structure comprising left and right parallel symmetric guide rail units. End beams are disposed on the left and right parallel symmetric guide rail units respectively, and a cross beam is connected between the left and right end beams. The lightweight gantry structure is characterized in that each guide rail unit comprises an I-beam; the end beams are arranged above the I-beams; the lower ends of the end beams are provided with fixed shafts; one end of each fixed shaft is provided with a roller; the peripheral surface of each roller and the upper end face of the corresponding I-beam are tangent; a clamping device is mounted on each end beam and comprises bearings mounted on two sides of the I-beam, and the bearings are fixed to the beam through guide shafts and nuts. The guide shafts on two sides of each I-beam include a linear guide shaft and an eccentric guide shaft. The lightweight gantry structure is reasonable in structure, stable in precision, reliable in performance, capable of accurately positioning and applicable to various severe environments and has sufficient rigidity; deformation and distortion caused by long-term reciprocation is avoided, production efficiency of products is greatly improved, and product quality is guaranteed.

Description

Light gantry structure
Technical field
The present invention 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 object of the invention is to overcome the deficiencies in the prior art, provide a kind of light gantry structure, rational in infrastructure, stable accuracy.
According to technical scheme provided by the invention, 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 present invention has the following advantages: the present invention 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
Fig. 1 is structural representation of the present invention.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the schematic diagram of guide assembly of the present invention.
The specific embodiment
Below in conjunction with concrete accompanying drawing, the invention will be further described.
As shown in FIG. 1 to 3: described light gantry structure comprises end carriage 1, crossbeam 2, I-steel 3, fixed axis 4, roller 5, bearing 6, the axis of guide 7, nut 8, moving body 9, welding gun 10 etc.
As shown in Figure 1, the present invention includes left and right parallel to the guide assembly arranging, the distance between the guide assembly of two groups of left and right is by required span exactness; On the guide assembly of two groups of described left and right, end carriage 1 is set respectively, connecting cross beam 2 between the end carriage 1 of the left and right sides arranges the moving body 9 that can move along crossbeam 2 on crossbeam 2, and welding gun 10 is installed on moving body 9;
As shown in Figure 3, described guide assembly comprises the I-steel 3 being embedded on ground, and end carriage 1 is positioned at the top of I-steel 3, in end carriage 1 lower end, fixed axis 4 is installed, and the end of fixed axis 4 arranges roller 5, and the upper surface of the periphery of roller 5 and I-steel 3 is tangent; On described end carriage 1, clamping device is installed, clamping device comprises the bearing 6 that is arranged on I-steel 3 both sides, and bearing 6 is fixing with end carriage 1 by the axis of guide 7 and nut 8 respectively; The axis of guide 7 of described I-steel 3 both sides is respectively straight-line guidance axle and the eccentric axis of guide, can to realize, be clamped and fix by the eccentric adjustment axis of guide.
The present invention 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 do not improved the production efficiency of product and guarantee product quality.
