Description
Technical field
The utility model relates to a kind of linear rail, relates in particular to a kind of simple in structure, low cost of manufacture, built-in twin shaft core roller linear rail that running precision is high.
Background technique
Linear rail is widely used in precise numerical control machine and machine industry etc., traditional linear rail generally comprises guide rail and slide block, is provided with roller on slide block, corresponding being provided with and the optical axis of roller interworking on guide rail, roller rolls along optical axis, thereby realizes slide block being slidably connected on guide rail.In structure because roller moves along optical axis, therefore the dimensional accuracy of optical axis and assembly precision are most important, it has directly determined the running precision of linear rail, but the optical axis in existing linear rail is generally first on guiding cheekn, to offer groove, again optical axis is inlaid in groove, owing to there is certain size error in groove and optical axis, when optical axis assembling simultaneously, also there is certain assembly error, therefore assembly precision often cannot ensure, make the running precision of linear rail low, directly affect the quality of linear rail.
Chinese patent discloses a kind of Double-axis track-type facilities (CN202438841U), comprise slide block and guide rail, the middle part of slide block is provided with guide-track groove, the bottom of guide-track groove is provided with some fixed holes, the left and right sides of guide-track groove is respectively equipped with some rollers, and roller is flexibly connected with slide block by nut, is provided with guide rail in guide-track groove, the middle part of the guide rail left and right sides is equipped with screw mandrel, and on guide rail, the position corresponding with fixed hole is provided with fixed hole two.This device is provided with the optical axis (screw mandrel) of answering interworking with pair of rollers on guide rail, rolling to realize the linear slide of slide block on guide rail by roller along optical axis connects, but this device exists optical axis assembly precision to ensure equally, make the running precision of linear rail low, directly affect the technical problems such as the quality of linear rail.
Summary of the invention
The utility model has mainly been to provide a kind of simple in structure, low cost of manufacture, built-in twin shaft core roller linear rail that running precision is high, having solved the optical axis assembly precision existing in prior art cannot ensure, make the running precision of linear rail low, directly affect the technical problem of quality of linear rail etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of built-in twin shaft core roller linear rail, comprise U-shaped guide rail upward of opening end and be located at the slide block of U-shaped guide openings end top, on two side in U-shaped guide openings end, be arranged with optical axis, the middle part of slide block is lifted with several rollers, roller extends between the opening end of U-shaped guide rail and keeps linear slide to be connected with after the optical axis interworking of both sides, the U-shaped guide rail madial wall that described optical axis is corresponding is provided with cambered surface sliding-rail groove, optical axis is inlaid in cambered surface sliding-rail groove, on the U-shaped guide rail outer side wall corresponding with cambered surface sliding-rail groove, be connected with several adjusting screw, adjusting screw extends horizontally to the interior also apical grafting of cambered surface sliding-rail groove on optical axis.Because optical axis is inlaid in cambered surface sliding-rail groove, several adjusting screw spin on guide rail outer side wall by the bottom correspondence at cambered surface sliding-rail groove, and adjusting screw horizontal-top is connected on optical axis, embed after corresponding cambered surface sliding-rail groove at optical axis, can optical axis be finely tuned in the horizontal direction by screwing in and screw out adjusting screw, ensure the assembly precision of optical axis, simple in structure, cost is low, and linear rail quality is guaranteed.
As preferably, described cambered surface sliding-rail groove and optical axis interworking, and be less than the optical axis height in cambered surface sliding-rail groove corresponding to the optical axis height outside cambered surface sliding-rail groove.In the time of cambered surface sliding-rail groove and optical axis interworking, make the area of contact of optical axis and cambered surface sliding-rail groove large, improve the intensity of optical axis, in the time that the optical axis height outside cambered surface sliding-rail groove is less than the optical axis height in cambered surface sliding-rail groove, the opening size that is cambered surface sliding-rail groove is less than shaft diameter, thereby avoid optical axis to deviate from cambered surface sliding-rail groove, improve reliability.
As preferably, on U-shaped guide rail corresponding to middle part, described cambered surface sliding-rail groove bottom surface, level is provided with several optical axises and regulates tapped through hole, and adjusting screw is screwed in optical axis and regulates on tapped through hole.The optical axis that adjusting screw is screwed in middle part, cambered surface sliding-rail groove bottom surface regulates on tapped through hole, even if regulate the outer ring surface middle part of the horizontal overhead of spiral shell at optical axis, and optical axis substantially horizontal turnover while guaranteeing to finely tune, Torque-adjusting is large.
As more preferably, the optical axis corresponding with described cambered surface sliding-rail groove regulates tapped through hole one end to be provided with counterbore.When optical axis regulates the front end of tapped through hole that counterbore is set, can shorten the processing dimension of optical axis adjusting tapped through hole, save processing cost.
As preferably, described adjusting screw is axially equally spaced along optical axis.In the time that adjusting screw is equally spaced, can ensure the equilibrium of optical axis Level tune size, further ensure the fitted position of optical axis.
Therefore, built-in twin shaft core roller linear rail of the present utility model has following advantage:
By the adjusting screw that spins on guide rail outer side wall corresponding to bottom in cambered surface sliding-rail groove, and make adjusting screw horizontal-top be connected on the middle part of optical axis, and can optical axis be finely tuned in the horizontal direction by screwing in and screw out adjusting screw, simple in structure, cost is low, has ensured the assembly precision of optical axis; When the opening size of cambered surface sliding-rail groove is less than shaft diameter, can avoid optical axis to deviate from cambered surface sliding-rail groove, improve reliability.
