Abstract
The invention provides an embedded disturbing moment unloading mechanism for unloading beam guide rails on a large-sized gantry machine. The mechanism comprises a cross beam, wherein a guide rail pressure plate is connected with the cross beam through an upper guide rail and a lower guide rail on the cross beam; an auxiliary guide rail is obliquely fixed above the cross beam; a pressure plate is fixed on the guide rail pressure plate; an elastic strutting piece is arranged between the pressure plate and a sleeve body; a rotating shaft of the sleeve body is connected with an idler wheel; the idler wheel is positioned on the auxiliary guide rail; and an adjusting mechanism is arranged between the pressure plate and the elastic piece. After installation, part gravity of the guide rail pressure plate and each slide part thereon can be decompressed on the auxiliary guide rail to reduce the bearing force of the guide rail under the cross beam, so that abrasion on the guide rail is reduced, sliding precision is further improved, and service life of the guide rail is prolonged; and the mechanism is obliquely arranged, so the mechanism greatly overcomes the disturbing moment of each part generated on the cross beam, and effectively plays a role in unloading the lower guide rail.
Description
Technical field
The present invention relates to a kind of unloading mechanism, particularly a kind of embedded disturbing moment unloading mechanism that its beam guideway is carried out off-load that is used on the large-sized gantry machine.
Background technology
Crossbeam by upright supports is arranged on the large-sized gantry machine, upper and lower guide rail is arranged on crossbeam, parts such as balladeur train, ram, main shaft are placed on the crossbeam by guide rail clip, and on crossbeam slidably.The deadweight of each parts of back is installed and adds the cutting force that produces man-hour and can produce disturbing moment to crossbeam, the guide rail of below is that load-bearing guarantees the precision of sliding again, and the guide rail of top mainly plays guide effect.This beam structure is bigger to the way rub of below, has a strong impact on its service life.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, alleviate the embedded disturbing moment unloading mechanism that is positioned at square guide rail holding capacity under the crossbeam, reduces to wear and tear, overcome the disturbing moment that the crossbeam upper-part produces crossbeam, overcome the deficiencies in the prior art.
Embedded disturbing moment unloading mechanism of the present invention comprises crossbeam 3, is connected with guide rail clip 2 by the upper and lower guide rail on the crossbeam 3, it is characterized in that: the upper fixed at crossbeam 3 has the secondary guide rail 12 that is obliquely installed; Intrinsic pressing plate 10 on guide rail clip 2 is provided with elastic supporting member for supporting optical member between pressing plate 10 and body 11, body 11 rotating shafts are connected with roller, and described roller is seated on the described secondary guide rail 12, is provided with guiding mechanism between pressing plate 10 and elastic component.
Embedded disturbing moment unloading mechanism of the present invention, wherein said roller are bearing 7, and are set with overcoat 8 in the outside of bearing 7 and are used for contacting with secondary guide rail 12.
Embedded disturbing moment unloading mechanism of the present invention, wherein elastic component is a butterfly spring 5, butterfly spring 5 is positioned at the endoporus place of body 11; Bolt 9 and the back of the body cap 4 of described guiding mechanism for being threaded with pressing plate 10.
Embedded disturbing moment unloading mechanism of the present invention, wherein secondary guide rail 12 is inlayed and is fixed on the crossbeam 3.
Embedded disturbing moment unloading mechanism of the present invention, install the rear rail pressing plate and on a part of gravity of each slide unit can decompose on the secondary guide rail by elastic component, alleviated the bearing capacity of square guide rail under the crossbeam, its wearing and tearing are reduced to some extent, further improved the slip precision, prolonged its service life, because this mechanism is obliquely installed, greatly overcome each parts to the disturbing moment that crossbeam produced, effectively played off-load effect lower guideway.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention.
The specific embodiment
As shown in Figure 1: 3 is the local section of crossbeam, and 2 is the guide rail clip that matches with crossbeam 3.Vertically be processed with the secondary guide rail mounting groove that is obliquely installed above transverse beam 3, secondary guide rail 12 is fixed in the groove by guide rail glue mosaic bonding.On guide rail clip 2, pressing plate 10 is arranged, on pressing plate 10, be threaded and adjusted bolt 9, and be provided with back of the body cap 4, when bolt 9 is adjusted to correct position, can fasten by back of the body cap 4 back ofs the body by bolting.11 is body, and the endoporus place is provided with butterfly spring 5 above body 11, is provided with backing plate between the termination of butterfly spring 5 upper ends and bolt 9.Bottom at body 11 is equipped with bearing 7 by rotating shaft 6, is set with in the outside of bearing 7 through heat treated wear-resisting overcoat 8, is rolling friction between overcoat 8 and the secondary guide rail 12.In order to reach the effect of balance, three these unloading mechanisms of cover are set at interval between crossbeam 3 and guide rail clip 2.
Claims (4)
