Through the setting on transition slope on the slider, eliminated the right angle " step " of existence between the slide in circulator and the slider, greatly improved the slider and at the guide rail dispatch stationarity in vogue that climbs to a high place, overcome the ball and moved the circulation dead point that very easily produces when this is located, also reduced the noise, prolonged the life of slider.
Description
Technical field
This utility model belongs to the rolling member field in optoelectronic integration, a kind of slide block that can realize the operation of high stationarity.
Background technology
Linear rolling guide is to replace sliding friction with rolling friction, and the Infinite Cyclic being done both fixed tracks by rolling element (ball or roller) is supported and transmits carrier and gives the linear motion pair of certain guiding accuracy.In brief, the big element of " guide rail, slide block, reverser " three can be divided into.From motor function, it is simply that " slide block " " guide rail " relatively passes through " circulation and the power transmission " that " rolling element " go round and begin again and complete the straight reciprocating motion of certain precision.The rolling of the ball in slide block is the most smooth and easy more advantageously reduces the vibration or impact produced in reciprocating motion.At present, the traditional line guide rail pair of China is all according to national standard manufacture, the rolling of the ball in slide block is the most smooth and easy more advantageously reduces the vibration or impact produced in reciprocating motion, it is provided with ball slideway with guide rail contact position on slide block, and inside slide block, it is provided with the back passage corresponding with ball channel, ball runs to the rotating channel in reverser again to back passage from ball slideway, it is achieved a shuttling movement gone round and begun again relative to guide rail.But existing standard rolling linear slide block, ball is from when ball slideway runs to rotating channel, because there is " step " of one 90 degree between rotating channel and ball slideway, i.e. rotating channel and the You Ge right angle, intersection of ball slideway, ball runs to this position between two slideways may bump against this right angle, as shown in Figure 2, A position in " step " i.e. figure, when ball runs to this position, frictional resistance is multiplied, easy stuck generation circulates dead point, also can produce impact noise, and then affect operation and the service life of whole guideway.
Summary of the invention
For solving above-mentioned technical problem, this utility model provides the slide block of the high stationarity of a kind of energy, can improve the stationarity that ball rolls, and reduces the noise impact running generation between slide block and guide rail, also extends the service life of whole guideway.
The technical solution of the utility model: a kind of slide block that can realize high even running, comprise body, described body rear and front end is provided with interior reverser, outer reverser, described interior reverser is located between body and outer reverser, interior reverser and outer reverser form rotating channel, and described interior reverser and outer reverser cross section are two isocentric circular arc；Described slide block bottom has the first groove, described first groove two ends are arranged with slideway, ball is set in described slideway, it is provided with the back passage corresponding with slideway near the first groove two ends on described slide block, described interior reverser arranges a transitional slope near side, slideway inside edge, and described transitional slope two ends connect with interior reverser, slideway inside edge respectively.Change the front and rear end of the slide block of traditional standard part and 90 degree of right-angled bends of inner surface of ball slideway, from slider angles, say to be exactly that the rib that intersects between front end face (or rear end face) and the inner surface of ball slideway of slide block is processed to form an inclined-plane, ball is run can be more smooth, eliminate this right angle so that ball moving is not limited by " stuck " of an angle of 90 degrees.
Further, the surface of described transitional slope and interior reverser plane tangent.
Further, described transitional slope is that rounding is connected with ball slideway inside edge.Rounding is less in knuckle curve friction more direct with slip inside edge than direct slope, and ball runs to rounding and turns subject to less resistance.So-called rounding is i.e. processed into cambered surface the turning corner angle between transitional slope and the edge of ball channel.
Further, the outer reverser being positioned at body portion is provided with an oil nozzle.
Further, described slideway is four row, is symmetrical arranged relative to the first groove, and four row slideways use 45° angle to arrange.Make the load born on all angles direction of whole slide block consistent.
Further, it is additionally provided with end seal baffle plate outside described outer reverser.
Further, described slide block upper surface is provided with the second groove of symmetry, and described upper surface is additionally provided with screw, and the upper surface of described screw and the second groove are positioned at different level.
The beneficial effects of the utility model: by the setting of transitional slope on slide block, eliminate the right angle " step " existed between the slideway in circulator and slide block, greatly improve slide block stationarity on guide rail during high-speed cruising, overcome the circulation dead point easily produced when ball runs at this, also reduce noise, extend the service life of slide block.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further so that technical scheme is clearer.
As shown in the figure, linear rolling guide includes slide block and is located at the guide rail 2 below slide block, the first groove 3 it is provided with below slide block, first groove 3 upper and lower part is correspondingly provided with slideway 4, ball 8 is set in slideway, the inside edge 41 of slideway 4 connects with the first groove 3, before and after slider body 1, two ends are provided with interior reverser 9, outer reverser 10, interior reverser is located between slider body and outer reverser, interior reverser and outer reverser form rotating channel 6, and the cross section of interior reverser and outer reverser is two isocentric circular arc；The slider body at the first groove two ends is provided with the back passage 5 corresponding with slideway, described interior reverser arranges a transitional slope 11 (figure cross-sectional shapes) near side, slideway inside edge, and transitional slope two ends connect with outer surface 91 (namely rotating channel is near the side of interior reverser), the slideway inside edge 41 (namely near the slideway of back passage side) of interior reverser respectively.Transitional slope is equivalent to an inclined-plane, for ball, has made ramp turning into from the right-angled bend of step, and the impulsive force of generation greatly reduces.
Unlike those described above, the transitional slope of this programme is that rounding is connected with ball slideway inside edge, i.e. be rounding transition at A point in Fig. 3.
Unlike those described above, the surface of transitional slope and interior reverser plane tangent.
Unlike those described above, described slideway is four row, is symmetrical arranged relative to the first groove, and four row slideways use 45° angle to arrange.Make the load born on all angles direction of whole slide block consistent.
Unlike those described above, the slide block upper surface of this programme is additionally provided with the second groove 7 of symmetry, and described upper surface is additionally provided with screw 13, and the upper surface of described screw and the second groove are positioned at different level.The surface avoiding slide block contacts with guide rail upper surface, reduces and only rolls, by the ball in slideway, the frictional resistance produced that moves reciprocatingly between slide block and guide rail.
Unlike those described above, the outer reverser of the body portion of this programme is provided with an oil nozzle 12.
Being more than preferred implementation of the present utility model, do not limit protection domain of the present utility model, the deformation made according to mentality of designing of the present utility model for those skilled in the art and improvement, within all should being considered as protection domain of the present utility model.
