Abstract
The utility model relates to a sliding block structure of a rolling linear guide rail, which comprises a guide rail and a sliding block frame shell, wherein the outer side of the guide rail is provided with 4 linear roller tracks; both sides of the guide rail are respectively provided with a reverser; each reverser comprises a retainer and a reverser O-shaped guide tube; and the retainer and the reverser O-shaped guide tube are mutually connected in a clamping manner. The utility model provides a butt type guide tube, thereby lowering the requirements for easily controlling the machining accuracy in the guide tube through ball holes of the sliding block shell; and meanwhile, in the use process, the motion friction resistance of steel balls is reduced, thereby realizing that the static friction is very low and the steel balls can move more smoothly, avoiding the occurrence of unnecessary retardation, collision and other similar situations, improving the accuracy and prolonging the service life.
Description
Technical field
The utility model relates to the slide block structure of rolling linear guide.
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.
Summary of the invention
In order to address the above problem, it is simple in structure that the utility model provides, and makes the slide block structure of the rolling linear guide of the smooth and easy motion of steel ball.
For realizing the purpose of the utility model, be achieved by the following technical solutions: the slide block structure of rolling linear guide, comprise guide rail and slider frame shell, the described guide rail outside is provided with 4 straight line raceways, the both sides of guide rail are respectively equipped with reverser, reverser comprises retainer and reverser O type conduit, described retainer and the mutual clamping of reverser O type conduit, reverser O type conduit is provided with 4 conduits, the straight line raceway in conduit and the guide rail outside mates mutually, described slider frame shell inboard is provided with two the ring-like raceways suitable with the guide rail outside, described conduit is plugged in the ring-like raceway of described slider frame shell inboard, the conduit of both sides interconnects at the inboard ring-like raceway of slider frame shell, and the ring-like raceway of described slider frame shell inboard is provided with rolling element, is provided with the groove that is complementary with rolling element in the described conduit.
As preferably, described retainer is provided with three dovetail groove, and retainer is provided with the arc shaped groove that mutually mates with described conduit.
The utility model provides a kind of conduit of dock, thereby reduced the requirement to machining accuracy in the slide block shell ball pore volume conduit easy to control, in use simultaneously, reduce the kinetic friction resistance of steel ball, thereby it is poor very little to obtain stiction, make the motion of steel ball more smooth and easy, avoided the generation of the situations such as unnecessary retardance, knock against each other, improved precision and working life.

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:
The slide block structure of rolling linear guide, comprise guide rail 1 and slider frame shell 2, described guide rail 1 outside is provided with 4 straight line raceways 3, the both sides of guide rail 1 are respectively equipped with reverser 4, reverser 4 comprises retainer 5 and reverser O type conduit 6, described retainer 5 and the 6 mutual clampings of reverser O type conduit, reverser O type conduit 6 is provided with 4 conduits 7, conduit 7 mates mutually with the straight line raceway 3 in guide rail 1 outside, described slider frame shell 2 inboards are provided with two ring raceways 10 suitable with guide rail 1 outside, described conduit 7 is plugged in the ring raceway 10 of described slider frame shell 2 inboards, the conduit 7 of both sides interconnects at slider frame shell 2 interior annular raceways 10, the ring raceway 10 of described slider frame shell 2 inboards is provided with rolling element 8, is provided with the groove 9 that is complementary with rolling element 8 in the described conduit 7.Described retainer 5 is provided with three dovetail groove 11, and retainer 5 is provided with the arc shaped groove 12 that mutually mates with described conduit 7, and rolling element 8 is steel ball.Three dovetail groove 11 plays more effective fixedly clamping, occurs violent vibrations in the use, and whole interior steel ball still can guarantee under original working state.
In use, steel ball 8 is by moving in slide block, when arriving arc shaped groove 12 position of retainer 5, since the design forming of arc shaped groove 12 one one side ring shape raceway 10 and integrating with that conduit 7 is connected, steel ball 8 enters in the ring raceway 10 along arc shaped groove 12, arrived by ring raceway 10 in the reverser 4 of opposite side, arc shaped groove 12 by the retainer 5 of opposite side enters conduit 7 again, pass in the groove 9 that groove 9 enters opposite side conduit 7, enter again the ring-like raceway 10 of opposite side from the arc shaped groove 12 of the retainer 5 of opposite side, the like this motion that makes of Zhou Erfu, so that the steel ball 8 of whole process is connected closely, simultaneously because the design of arc shaped groove 12 does not have steel ball 8 retardances yet, knock against each other, phenomenon has some setbacks, used the linking design of two sections conduits 7 at the raceway place of ring raceway 10 1 side straight lines, so that original higher requirement on machining accuracy reduces, the reverser O type conduit 6 of simultaneously segmentation is easier to processing and precision control with the mold injection ratio, and such improvement is so that guaranteed steel ball 8 and bearing under the operating mode of load and can roll freely smooth and easy by low noise.Article four, the fixing engineering plastics cage in O type conduit 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.
