Description

A kind of straight-line guide rail slide block
Technical field
The utility model belongs to industrial automation equipment technical field, is related to a kind of straight-line guide rail slide block.
Background technology
Line slideway is also known as line rail, slide rail, linear guides, linear slide rail, can be negative in height for straight reciprocating motion occasion High-precision linear motion is realized in the case of load.Line slideway can be divided into according to the difference of roller:Roller line slideway.Circle Post line slideway, ball line slideway.And because ball is applicable high-speed motion, coefficient of friction is small, high sensitivity, therefore ball is straight Line guide rail is in precision equipment using more extensive.
Chinese patent application (application number:201610513931) a kind of straight-line guide rail slide block, including slider body are disclosed, The both ends of the glide direction of slider body are respectively fixed with an outer circulation device, are respectively equipped with and lead on slider body and outer circulation device The slider body guide rail hole and outer circulation conductance rail hole of the shape of cross section adaptation of rail.Ball is in slider body and outer circulation device group Into circulation canal in Infinite Cyclic roll so that slider body opposite rail slide.In existing line slideway, it is necessary to Ball fills up circulation canal, and ball mutually reclines with ball, ball is promoted ball to realize circulation.
And in order to ensure that ball is circulated, it is necessary to configure retainer preferably in circulation canal.Chinese patent application (Shen Please number:201310737803) disclose a kind of line slideway retainer optimization structure, including two revolution guidance parts, two Longitudinal guidance part, revolution guidance part set turning slot, are set on longitudinal guidance part and mend pearl breach.Although this design can guide Ball circulating rolling in circulation canal, but also the steel ball of reduction can be supplemented, but it still needs to rely on steel Pearl promotes steel ball to realize circulation, steel ball is reclined in the rolling with steel ball and touches, so as to produce Relative friction, both accelerates steel The abrasion of pearl, adds noise again.Equally steel ball is also set easily therefrom to deviate from moreover, mending Zhu Kou design, so as to cause not Necessary trouble.
The content of the invention
The purpose of this utility model is above mentioned problem be present for existing technology, it is proposed that a kind of straight-line guide rail slide block, Technical problem to be solved in the utility model is:How ball preferably circulating rolling guide rail slide block in is made.
The purpose of this utility model can be realized by following technical proposal:A kind of straight-line guide rail slide block, including sliding block sheet Body, the circulation canal rolled for ball-recirculation is provided with the slider body, the guarantor of chain-type is provided with the circulation canal Holder, the retainer include retainer and chain, and the retainer has limit chamber, and the ball is arranged at the limit chamber Interior, the ball can be rolled partly with circulation canal and guide rail against simultaneously relative respectively from limit chamber is projecting inward, the chain Multiple retainers are joined end to end along circulation canal.
The setting chain-type retainer in circulation canal, the limit chamber ball in circulation canal being caught in retainer, Them is rolled in limit chamber, then retainer is connected one by one by chain, each ball is defined in circulation In passage, it will not lose.The design of chain-type retainer makes to be in contact between ball, and it is relative with ball to avoid ball Rub and cause to wear, extend the service life of ball, and avoid ball and produce noise with ball friction or collision.Protect Holder is in closed ring shape, retainer is drawn the retainer at rear when moving, and the ball at rear is followed the rolling in front Pearl rolls, and forms circulation.
In above-mentioned straight-line guide rail slide block, the retainer includes bottom plate and two projections, is provided with bottom plate circular logical Hole, the diameter of through hole are less than the diameter of ball, and the upper surface integrally connected of two projections and bottom plate is simultaneously located at described respectively The distance between the both sides of through hole, two described projections are less than the diameter of the ball, and each projection is opened by through hole side Fluted, the bottom plate and two projections surround the limit chamber, the ball can simultaneously between two projections and Expose in through hole and respectively with guide rail and circulation canal against.Reeded projection is opened for two to be limited to ball as claw In limit chamber, ball is set to be not easy limit chamber.And ball is caught in from projection upper end spacing for the bump design of similar claw During chamber, elastic deformation can occur for projection, to the direction deflection away from limit chamber, make ball be easier to enter limit chamber, work as rolling After pearl enters limit chamber, projection restores again blocks ball.
In above-mentioned straight-line guide rail slide block, also have on each retainer by the bottom plate and two projections The oil storage tank surrounded, the oil storage tank connect with the limit chamber.Oil storage tank recline limit chamber setting, in oil storage tank add profit After consistent lubricant, ball can bring lubricating grease into limit chamber when rolling, and reduce the friction of ball and spacing cavity wall, roll ball More smooth, abrasion is less, and noise is lower.
In above-mentioned straight-line guide rail slide block, retainer is made up of nylon.The weight of nylon cages is lighter, rolls ball Load when dynamic is less, and the frictional force of nylon and ball is smaller, and the abrasion to ball is also small, can extend the use of ball Life-span, caused by noise it is also lighter.The retainer of nylon can be by being molded one-shot forming, and processing is more convenient.
In above-mentioned straight-line guide rail slide block, the circulation canal is multiple.Multiple circulation canals are set, rolling can be increased Contact quantity of the pearl with guide rail, makes the slip of sliding block more steady, the higher load of carrying.
In above-mentioned straight-line guide rail slide block, the ball is ceramic balls.Ceramic balls have it is in light weight, it is corrosion resistant Feature, slider body is set to can adapt to more complicated environment, and rotation is lighter, and noise is lower, and the life-span is longer.
Compared with prior art, this straight-line guide rail slide block has advantages below:
1st, ball can be limited in retainer by the utility model, make to keep certain spacing between ball and ball, It will not collide, in the life-span of the ball of extension, reduce noise.
2nd, the utility model sets retainer that ball links together, and traction ball rolls along circulation canal, makes rolling The circulation of pearl is more smooth to be also avoid ball abjection circulation canal and loses, and ensure that the stability of work.
3rd, the design of oil storage tank reduces the friction of ball and spacing cavity wall, rolls ball more smooth, and noise is lower, Service life is longer.
