Abstract
The utility model discloses a miniature rolling linear guide rail pair which has the advantages of compact structure and strong universality. The utility model comprises a miniature guide rail, a miniature slide block, a steel ball, a reverser and a holding stand, wherein the miniature slide block is provided with a groove of which the shape is matched with the shape of the cross section of the miniature guide rail; both sides of the groove and both sides of the miniature guide rail are respectively provided with a row of rolling tracks which are mutually matched; the steel ball for bearing load is arranged in the rolling tracks; the miniature slide block is arranged on the miniature guide rail through the steel ball and can move axially along the miniature guide rail; the reverser which is used for making the steel ball steered is fixed at both ends of the miniature slide block; the miniature slide block and the reverser are both fixed by the holding stand. The utility model is provided with two rows of Gothic double-arc rolling tracks, and has the advantages of small mounting dimension and high precision. The utility model is widely used for light load conditions. The utility model is especially suitable for occasions, such as measuring devices, computer embroidery machines, precision carving machines, electric machines, medical devices, etc.
Description
One, technical field
The utility model relates to a kind of linear rolling guide, specifically a kind of miniature linear rolling guide.
Two, background technique
At present, linear rolling guide generally is made up of guide rail, slide block, steel ball, back device, retainer etc.Its working principle is to roll in the raceway of guide rail and slide block formation by steel ball, realizes the straight line motion of linear rolling guide.Along with the continuous development of machine industry, machine industry more and more trends towards modularization production.In order to adapt to of the requirement of lathe industry development to rolling function parts product, at electronics, that the mechanical industry of embroidering presses for a kind of volume is littler, the bearing capacity height, the running precision height, reliable linear rolling guide moves.The shortcoming of existing linear rolling guide is: volume is bigger, can not satisfy the specific (special) requirements of some industry, particularly in compact structure, occasion that volume requirement is high, has limited the production and the manufacturing of equipment.
Three, summary of the invention
The purpose of this utility model provides the miniature linear rolling guide of a kind of compact structure, highly versatile, and this miniature linear rolling guide design has the Gothic duplex circular ares profile race of two rows, and installation dimension is littler, is widely used under the underloading situation.
The purpose of this utility model is achieved through the following technical solutions:
A kind of miniature linear rolling guide, it is characterized in that: it comprises miniature guide rail, miniature slide block, steel ball, back device and retainer, on miniature slide block, be provided with and the suitable groove of the sectional shape of miniature guide rail, be respectively equipped with the raceway that a row cooperatively interacts in the both sides of groove and the both sides of miniature guide rail, the steel ball of bearing load is arranged in the raceway, miniature slide block is arranged on the miniature guide rail by steel ball and can moves axially along miniature guide rail, the back device that is used for steel ball is turned to is fixed on the two ends of miniature slide block, and miniature slide block and back device are fixed by retainer.
In the utility model, for guarantee steel ball can be in raceway smooth rotation, the raceway in the described groove is the two arc structures of Gothic off-centre, every row steel ball is located with raceway at 2 at 45 ° and is contacted also stressed.
For preventing that effectively dust from entering slide block inside, the utility model is equipped with the dust sealing end cap at back device two ends.
The utility model is put into an amount of steel ball between guide rail and slide block, make between guide rail and the slide block and become rolling friction by sliding friction, when steel ball rolls through two raceways that harden and precision grinding processes on guide rail, steel ball enters raceway again by the back device again in the slide block end, steel ball carries out rolling motion like this again and again, at back device two ends the dust sealing end cap is housed, can prevents effectively that dust from entering slide block inside.
Miniature linear rolling guide described in the utility model can become minimum with linear rail and slider designs to greatest extent, the two arc structures of unique Gothic off-centre, make every row steel ball all 45 ° locate 2 stressed, and in limited space, used the steel ball of maximum allowable diameter, guaranteed that bearing capacity meets the demands.Carrying a type linear rolling guide with existing four directions to grade compares, the utlity model has that volume is little, precision is high, efficient is high, load is big, the life-span is long, the four directions to etc. carry, characteristics such as wearing and tearing are little, low energy, friction factor are little, compact structure, highly versatile, realized the requirement of " light, thin, short, little ", the specific (special) requirements of some industry be can satisfy, compact structure, occasion that volume requirement is high are specially adapted to.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the two arc structure schematic representation of Gothic off-centre described in the utility model.
Five, embodiment
The miniature linear rolling guide of a kind of GGC described in the utility model comprises miniature guide rail 1, miniature slide block 2, steel ball 3, back device and retainer.Be provided with the groove 4 suitable with the sectional shape of miniature guide rail 1 on miniature slide block 2, be respectively equipped with the raceway 5 that a row cooperatively interacts in the both sides of groove 4 and the both sides of miniature guide rail 1, the steel ball 3 of bearing load is arranged in the raceway 5.Raceway 5 in the groove 4 is the two arc structures of Gothic off-centre, every row steel ball 3 and raceway 5 are located at 2 at 45 ° and are contacted and stressed, and every steel ball 3 all is subjected to axial force and radial force, closely cooperates between each steel ball 3, can be provided with lubricating grease between each steel ball 3, steel ball 3 can be in raceway 5 smooth rotation.Miniature slide block 2 is arranged on the miniature guide rail 1 and can moves axially along miniature guide rail 1 by steel ball 3, and the back device that is used for steel ball 3 is turned to is fixed on the two ends of miniature slide block 2, and miniature slide block 2 and back device are fixed by retainer.For preventing that dust from entering miniature slide block 2 inside, is equipped with the dust sealing end cap at back device two ends.
