Description
Technical field:
The utility model relates to a kind of permanent pre-profiling linear rolling guides.
Background technique:
Common linear rolling guide is mainly to pass through the interference for changing slide body, guide rail, rolling element (ball or roller)
Measure to set the precompressed of guideway, thus the initial interference of guideway be it is constant, due to fretting wear in use process
It deposits, so its magnitude of interference can constantly reduce therewith, precompressed is constantly reduced, it is usually expressed as 2 stages:
1) guideway use is lost fast in running-in period precompressed, and the rigidity and precision of early stage influence equipment are obvious, lathe rigidity
Forfeiture a part therewith, and the state that can then tend towards stability in a period of time；
2) sliding block raceway, guide rail raceway, rolling element is used for a long time as the final precompressed of the increase of abrasion can be lost to the limit
Even there is clearance condition, so that the rigidity and precision of equipment exhaust.
So the main failure forms of the advanced CNC linear rolling guide are precompressed forfeiture at present, when rolling is led
After rail pair precompressed is lost, rigidity, the precision of lathe, which will receive, to be seriously affected, and the maintenance mode of such case occurs in lathe at present
To restore its precompressed, use cost is high for the guideway predominantly more renewed or replacement rolling element (roller or ball).
Summary of the invention:
The utility model is to provide a kind of permanent pre-profiling rolling linear to solve the above-mentioned problems of the prior art
Guideway.
Technical solution used by the utility model has: a kind of perseverance pre-profiling linear rolling guide, including guide rail, sliding block
Body, rolling element and reverser, the slide body are slidably connected on guide rail by rolling element, and two reversers are set to the two of slide body
End, further includes roller, wedge block, piston cylinder and sliding block raceway body, the two sliding block raceway bodies along guide rail length direction
It is plugged in slide body, and is formed with sliding cavity and permanent spacer, the rolling element between each sliding block raceway body and slide body
In sliding cavity；
It is inserted into a wedge block at the both ends of permanent spacer, and each wedge block is fixedly connected with the piston of piston cylinder；?
Roller is equipped between wedge block and slide body and between wedge block and sliding block raceway body.
Further, the roller includes roller body and retainer, and roller body is set in retainer, the axis side of roller body
To perpendicular with the direction of motion of slide body.
Further, the sliding block raceway body and the isometric setting of slide body, and the both ends of sliding block raceway body pass through described two
Reverser is positioned in slide body.
The utility model has the following beneficial effects:
The utility model can keep precompressed constant size from beginning to end, fundamentally solve guideway precompressed and lose institute
Caused by lathe rigidity, precision lose the problem of, substantially prolong the service life of guideway, it is ensured that the permanent Gao Gang of lathe
Property, high-precision operate, it is significant.
Detailed description of the invention:
Fig. 1 is the utility model three-dimensional figure.
Fig. 2 is the utility model left view.
Fig. 3 is the section plan of the utility model.
Fig. 4 is the precompressed schematic diagram of the utility model.
In figure:
1, guide rail；2, slide body；3, roller；4, wedge block；5, piston cylinder；6, sliding block raceway body；7, rolling element；8, back
Device；9, piston.
Specific embodiment:
The utility model will be further described below with reference to the accompanying drawings.
As shown in Figure 1 to Figure 4, a kind of permanent pre-profiling linear rolling guide of the utility model, including guide rail 1, slide body 2, rolling
Kinetoplast 7, reverser 8, roller 3, wedge block 4, piston cylinder 5 and sliding block raceway body 6, slide body 2 are slidably connected at by rolling element 7
On guide rail 1, two reversers 8 are set to the both ends of slide body 2.Two sliding block raceway bodies 6 are plugged in cunning along the length direction of guide rail 1
Sliding cavity and permanent spacer are formed in block 2, and between each sliding block raceway body 6 and slide body 2, rolling element 7 is set to sliding
It is intracavitary.It is inserted into a wedge block 4 at the both ends of permanent spacer, and each wedge block 4 is fixedly connected with the piston 9 of piston cylinder 5.?
Roller 3 is equipped between wedge block 4 and slide body 2 and between wedge block 4 and sliding block raceway body 6.
The structure of the structure of reverser 8 and reverser 8 on slide body 2 is the prior art in the utility model, therefore
The utility model no longer repeats the specific structure and mounting means of reverser 8.
Roller 3 includes roller body and retainer, and roller body is set in retainer, the axis direction and slide body 2 of roller body
The direction of motion it is perpendicular.
The installation of mounting structure between roller body and retainer and retainer in the utility model in slide body 2
Mode is prior art conventional means, therefore the utility model repeats no more.
Sliding block raceway body 6 and the isometric setting of slide body 2, and the both ends of sliding block raceway body 6 are positioned by two reverser 8
In in slide body 2.
The cardinal principle of the utility model are as follows:
Two piston cylinders 5 are respectively arranged at guideway both ends, provide constant pressure f by oil pressure (or other augmentors),
Push piston 9 that wedge block 4 is driven to push roller 3, roller 3 pushes sliding block raceway body 6, so i.e. in sliding block, rolling element and guide rail
Between produce constant precompressed.
Due to the rigidity and precompressed value direct proportionality of guideway, so higher precompressed in order to obtain, in precompressed knot
It is provided with wedge block 4 in structure, powerful thrust F is generated by the bevel edge effect of wedge block, power amplification principle is as follows: F=f*tan θ (θ
For the angle of bevel edge and F).
Since thrust f is constant, so F=f*tan θ is also constant, guide rail, sliding block raceway when rolling guide-rail pairs
Precompressed will not change therewith when body, rolling element generate abrasion, to realize the perseverance of guideway in use
Pre-compressed effect, to solve the problems, such as that numerically-controlled machine tool is lost because of lathe rigidity, the precision caused by guideway precompressed forfeiture.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
It for art personnel, can also make several improvements without departing from the principle of this utility model, these improvement also should be regarded as
The protection scope of the utility model.
