Abstract
The utility model relates to a precise rolling guiding rail pair, which is provided with a guiding rail and a sliding block. Four arc grooves are arranged on the outer wall of the guiding rail, four arc grooves are arranged on the inner wall of the sliding block, and the arc grooves of the guiding rail are matched with the arc grooves of the sliding block so as to form a rolling path. A steel ball and a retainer are installed in the rolling path, and the guiding rail and the sliding block are connected through the steel ball in rolling mode. A returning device is installed at the end portion of the sliding block, and a dustproof sealing end cover is installed at the end portion of the returning device. When the guiding rail and the sliding block are in relative motion, the steel ball rolls along the rolling path of the guiding rail and rolls back to the rolling path through the returning device at the end portion of the sliding block, and the steel ball is in circle rolling motion. The end portion of the returning device is provided with the dustproof sealing end cover, thereby effectively preventing dust and scraps from entering the inside of the sliding block.
Description
Technical field
The utility model relates to a kind of accurate rolling guide-rail pairs.
Background technique
Linear rolling guide is put into suitable steel ball by guide rail, slide block, steel ball, back device, retainer etc. between guide rail and the slide block, make the sliding friction between the slide block become rolling friction.But existing linear rolling guide has no dust guard, and dust, bits end get into slide block inside easily, influence the working life of linear rolling guide.
The model utility content
The technical problem that the utility model will solve is: overcome the deficiency of existing technology, a kind of accurate rolling guide-rail pairs is provided, can prevent effectively that dust, bits end from getting into slide block inside, prolongs the working life of rolling guide-rail pairs.
The utility model solves the technological scheme that its technical problem adopted: a kind of accurate rolling guide-rail pairs, have guide rail, slide block, and described guide rail outer wall has 4 arc grooves; Described slide block inwall has 4 arc grooves; The arc groove of guide rail cooperates the formation raceway with the arc groove of slide block, steel ball and retainer are installed in the raceway, and guide rail rolls through steel ball with slide block and is connected; Described slide block end is equipped with the back device, and back device end is equipped with the dust sealing end cap.
The beneficial effect of the utility model is: when guide rail and slide block were done relative movement, steel ball rolled along the raceway on the guide rail, and steel ball returns raceway through the back device again in the slide block end, and steel ball goes round and begins again carries out rolling motion.Back device end is equipped with the dust sealing end cap, can prevent effectively that dust, bits end from getting into slide block inside.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the structural representation of the utility model;
Wherein: 1. slide block, 2. steel ball, 3. guide rail.
Embodiment
Combine accompanying drawing that the utility model is further described now.The schematic representation that these accompanying drawings are simplification is only explained the basic structure of the utility model in a schematic way, so it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of accurate rolling guide-rail pairs has guide rail 3, slide block 1; Guide rail 3 outer walls have 4 arc grooves, and slide block 1 inwall has 4 arc grooves, and the arc groove of guide rail 3 cooperates the formation raceway with the arc groove of slide block 1; Steel ball 2 and retainer are installed in the raceway; Guide rail 3 rolls through steel ball 2 with slide block 1 and is connected, and slide block 1 end is equipped with the back device, and back device end is equipped with the dust sealing end cap.
When guide rail 3 and slide block 1 were done relative movement, steel ball 2 rolled along the raceway on the guide rail 3, returns raceway through the back device again at slide block 1 end steel ball 2, and steel ball 2 goes round and begins again carries out rolling motion.Back device end is equipped with the dust sealing end cap, can prevent effectively that dust, bits end from getting into slide block inside.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
