Abstract
The utility model relates to a sliding block structure of a rolling linear guide rail, which comprises reversers (1) arranged at both sides and a sliding block frame shell (2) connected between the reversers (1), wherein the sliding block frame shell (2) is composed of an upper frame shell (3) and a lower frame shell (4) which are connected in a clamping manner; the inner side of the lower frame shell (4) is provided with two annular roller tracks (5); the upper frame shell (3) is provided with guide rail grooves (8) matched with the annular roller tracks (5); and the reversers (1) are provided with arc-shaped grooves (10) matched with the annular roller tracks (5).
Description
Technical field
The utility model relates to the rolling linear guide slide block structure.
Background technique
The industries such as domestic numerical control machine tool manufacturing, printing press machinery, mechanical, the extraordinary building materials abrasive machine of engraving machine.A large amount of such straight-line motion mechanisms of linear guide pairs that use in many automatic processing machine tools.Domestic present linear guide pairs retainer, when guide rail and slide block were made linear relative movement, steel ball is the rolling path rolling on the guide rail just, and the steel ball in the slide block enters backhaul hole raceway by the backhaul device, and steel ball makes to go round and begin again straight-line rolling.Such design is because guide rail is long, there is not to guide the auxiliary spare part of steel ball motion, when the machining of slide block ball is led the way the hole, be difficult to guarantee accurately, expense is higher, hanging down and can't guarantee again from machining accuracies such as degree, cylindricities in its hole, easily produces steel ball retardance, knock against each other, the phenomenon that has some setbacks, and affects the whole straight line moving-mass of guiding pairs product.Have the slide block structure of applicable and small-sized double track now when guide rail is extracted, can draw steel ball along band to shed, not have good fixation method, can only be fixing by binding outside retainer, can not avoid out steel ball to drop fully like this, and consume huge at the manpower and materials cost.
Summary of the invention
In order to address the above problem, it is simple in structure that the utility model provides, and can effectively control to make steel ball not occur dropping the rolling linear guide slide block structure of smooth and easy motion.
For realizing the purpose of the utility model, be achieved by the following technical solutions: the rolling linear guide slide block structure, comprise the retainer of both sides and be connected to the middle slider frame shell of retainer, the slider frame shell is formed by added shell and the clamping of undercarriage shell, undercarriage shell inboard is provided with two ring raceways, described added shell is provided with the guide-track groove that is complementary with ring raceway, and described retainer is provided with the arc shaped groove that is complementary with ring raceway.
As preferably, outside, described undercarriage shell both sides is provided with fixture block, and described retainer is provided with the draw-in groove that mutually mates with fixture block.
As preferably, be equipped with projection on described return device and the undercarriage shell.
The utility model provides the mode of a kind of retainer and the clamping of slider frame shell, whole tightness is better, in the situation that does not need other assistant tools, steel ball can not drop when having guaranteed that guide rail is extracted, make the motion of steel ball more smooth and easy, avoid the generation of the situations such as unnecessary retardance, knock against each other, improved precision and working life, reduced the manpower and materials cost.

Fig. 2 is a kind of structural representation of the utility model embodiment;
Fig. 3 is the structural representation of the utility model embodiment slider frame shell 2.
Embodiment
Below in conjunction with accompanying drawing 1-3, the embodiment of the technical solution of the utility model is described in further detail.
Embodiment: rolling linear guide slide block structure, the return device 1 and the slider frame shell 2 that is connected to return device 1 centre that comprise both sides, slider frame shell 2 is formed by added shell 3 and 4 clampings of undercarriage shell, undercarriage shell 4 inboards are provided with two ring raceways 5, described added shell 3 is provided with the guide-track groove 8 that is complementary with ring raceway 5, and described retainer 1 is provided with the arc shaped groove 10 that is complementary with ring raceway 5.Outside, described undercarriage shell 4 both sides is provided with fixture block 6, and described retainer 1 is provided with the draw-in groove 7 that mutually mates with fixture block 6.Be equipped with projection 9 on described return device 1 and the undercarriage shell 4.The material of return device 1 and undercarriage shell 4 is engineering plastics, and the material of added shell 3 is Bearing Steel Ger15.
In use, fixedly remain on the guide rail by projection 11, frame shell 3 and undercarriage shell 4 by the multilayer clamping very firmly, steel ball is in ring raceway 5 interior motions, cycle of motion is to carry out lane change to enter inboard raceways when being rolled into arc shaped groove 10, guaranteed the steel ball motion that Zhou Erfu makes in slide block, born under the operating mode of load and can roll freely smooth and easy by low noise.Return device 1 and slider frame shell 2 have formed an inner sealing state, steel ball moves in this sealing state, but need to be from installing upper extraction guide rail, since Seal Design be connected connection, inner steel ball can be along with the external force of stirring is extracted out, cause the phenomenon of being scattered, simultaneously original higher requirement on machining accuracy reduces, and such improvement is so that guaranteed steel ball and bearing under the operating mode of load and can roll freely smooth and easy by low noise.Article two, the fixing engineering plastics cage in ball row hole is so that easy processing, and leading the way simultaneously makes steel ball low noise, long-life, highi degree of accuracy, more smooth and easy motion.
