Description
Technical field
The present invention relates to linear guidance device technical fields, in particular to normal pressure heavy-load column rolling guide-rail pairs, are a kind of
The machine components of brand new ideas combine, and application range is very extensive, and specifically stating is exactly a kind of novel straight line scrolling function
Component.
Background technique
The mechanical development history of the mankind and the development history of scientific and technological progress.The plane of previous two machine components is mutually transported
It is dynamic to be known as low secondary guide rail, see Fig. 1.Low pair guide rail movement confficient of static friction is larger, and the driving power of power source is big, and piece surface exists
Yi Fare in movement, it is easy to wear, it is not able to satisfy production needs.Occur in constantly production practices are groped backward two parts it
Between rolling, i.e., increased in two part movement planes ball, roller be rolling element be known as higher pair guide rail, see Fig. 2.Higher pair is led
The static and dynamic friction coefficient of rail movement is smaller, thus driving power is small, and part is not easy to generate heat, not easy to wear.Typical case be with
The preceding low secondary guide rail of linear motion used is generally changed to the higher pair guide rail of straight line rolling, and emerges the production of many higher pair guide rails
Producer.So that mechanical linear motion technology has been stepped major step and achieves good application effect.
Be specifically described again: linear rolling track is divided to ball and two kinds of roller.One is the straight line that steel ball is rolling element rollings
Dynamic guide rail, is shown in Fig. 3.The raceway carried is point contact, therefore bearing capacity is low.It is also easy to produce vibration in work operational process, it cannot
Bear the processing of big cutting force, be not able to satisfy equally engineering goods it is growing in requirement.Later, guide rail form develops again
For the linear roller rolling guide that a kind of roller is rolling element, figure is seen, 4.Four are processed in 45 degree of distributions in guide rail two sides
Plane raceway, four column rollers contact.For ball rolling guide, the bearing capacity of guideway is increased really.But
It is following to produce service performance problem again.Because the stress roller surface of sliding block is located at the opening portion of sliding block, bearing load is up to one
After fixed number value, there are horizontal components on 45 degree of directions, and sliding block opening portion is forced to have dilatating and deformable.Lead to the rolling characteristics of guideway
It is greatly reduced with bearing capacity.Even rolling element is caused to have sliding phenomenon during exercise under certain situation.Once sliding, is bound to
Guide pass is pulled out into gash and is scrapped.
To solve the above problems, inventor designs a kind of novel heavily loaded guide rail of linear roller rolling, Fig. 5 is seen.
The roller that heavy load is born in sliding block is placed in the plane of rail crown, guide rail two sides retain two roller path planes, real
Now " heavy duty " truly, referred to as " normal pressure heavy-load column rolling guide-rail pairs ".
Summary of the invention
The purpose of the present invention is invent design for the deficiency in straight-line rolling guide set performance currently on the market
Novel load-carrying, super-heavy load linear rolling track, with meet different user preferably, higher use demand.
The technical solution of the present invention is to provide normal pressure heavy-load column rolling guide-rail pairs, comprising: guide rail 1 and matched cunning
Block 2,1 top surface of guide rail are subject to move the main motion face of heavily loaded object normal pressure, have the big roller 3 of a column to be located at the top of guide rail 1
Face, 1 two sides of guide rail are the guide surfaces of bearing capacity, have the small roller 4 of two column to be each positioned at side, constrained motion object or so and radial rotation
The deviation tendency turned, the both wings of the sliding block 2 are equipped with flange 5, and three column rollers are placed in three planes by grinding of sliding block 2
On, Infinite Cyclic operation is made by recoverable capsule 6.
Further by taking 45 type guide rail of specification as an example, big 3 diameter of roller is 6mm, length 30mm.
Further 3 both ends of the roller design has small stair, and small stair diameter is 2mm, length 2mm.
The angle in further small 4 center of roller and the direction of vertical bearing capacity is 45 degree.
Further small 4 diameter of roller is 4.5mm, length 6mm.
The further 1 main motion face groove width of guide rail and length are that the big roller 3 of 30mm has the gap 0.1mm.
Further guide rail 45 degree of the 1 two sides angle guide surface and the top surface primary clamping on slideway grinder is ground, and three
Guide rail roller surface straightness is consistent.
Compared with prior art, the beneficial effect comprise that by two column of traditional roller guide sliding block open end
Roller is merged into the big roller of a column and is placed in rail crown slide block slot, sees Fig. 5, and big roller is made not depart from cunning under any situation
Block.Carrier passes through roller for gravity P vertical transmission to guide rail top surface, stress P, component zero.Fig. 4 roller rolling guide
Carrier is by two column roller actions of sliding block opening portion by gravity P on two side rails in 45 degree of directions of guide rail, stress P
× sin45 °, there are cross component forces for sliding block.The bearing capacity of roller rolling guide is bigger, and the cross component force of sliding block opening portion is bigger,
Lead to the dilatating and deformable that is open, seriously affects the normal operation of sliding block, or even roller sliding phenomenon occur.
The normal pressure heavy-load column rolling guide-rail pairs that the present invention is designed for various guide rail performance shortcomings currently on the market,
Main bearing capacity is the big roller acted in rail crown plane, and contact width is greater than the 45 degree of direction rollings of Fig. 4 roller rolling guide
Column contact width.Normal pressure heavy-load column rolling guide-rail pairs rated static load is much larger than Fig. 4 roller rolling guide rated static load.With
Specification is for diameter 4.5mm roller guide pair, Fig. 4 is directly the sum of two column rollers and guide pass contact length through 4.5mm roller
For 12mm.The main carrying roller of Fig. 5 column rolling guide and guide level contact length are 30mm, are the 2.5 of Fig. 4 roller rolling guide
Times, and there is no cross component force.The heavy load that it is born is normal pressure, and effect is much larger than Fig. 4 roller rolling guide.
Disposal load (the cutting force load in processing part) because of the above advantage, in dynamic load rating of the present invention and work
Rigidity also greatly enhance.Thus the working performance of Fig. 5 normal pressure heavy-load column rolling guide-rail pairs is close to lathe hard rail.Reach i.e.
There is the light operation of sliding rail, and has the cutting effect of hard rail rigidity.
Rail height of the present invention decreases compared with conventional guide rails, runs more stable.
Main stress face of the present invention is run in guide level, compared with conventional guide rails for 45 degree of bevel directions are run, sliding block
Rollability is more preferable.
The more traditional roller guide of the present invention is more simple in recoverable capsule design aspect.There is the rolling of four column in 45 degree of directions of conventional sliders
Column, recoverable capsule end face is because structure limits, and recoverable capsule raceway has superposition, and structure is complicated, and craftsmanship is bad.45 degree of sides of present invention slider
To only two column raceways, roller circulation is more smoothly.
The guide rail of equipment needed for the present invention installs good compatibility.Setting for roller rolling guide in Fig. 4 can especially be shared
Standby, more fast and simple in replacement development, applicability is more preferable.
Simple structure of the present invention, use is easy, with good application prospect.
