Description

A kind of guides with high precision mounting structure
Technical field
The utility model relates to a kind of linear motion platform, particularly relates to a kind of guides with high precision mounting structure.
Background technique
Ball screw guide rail slide block movement platform is a kind of building mode of linear motion platform, uses comparatively extensively in electromechanical integration equipment, and it mainly comprises leading screw, feed screw nut, guide rail and slide block, and the guide rail mounting base of carrying these several members.
Common, the assembly precision of main member is one of key factor that influence the moving platform running precision, if the precision of member height and assemble badly not only can not obtain very high running precision, and very easily cause the damage of key member, thereby lose original performance.Therefore, the assembling mounting structure of the key member of platform and the performance optimization design of carrying the guide rail mounting base of these key members are difficult points of platform design.
Wherein, because the stroke of guide rail is long, and attachment face is big, cause distortion easily, make its assembling repair the difficulty maximum of accent, therefore, the quality that guide rail is installed directly influences slide block stability of motions and smoothness thereon, and then has influence on the running precision of moving platform.
The precision of mainly paying close attention to when generally speaking, guide rail is installed comprises: the straightness accuracy that single guide rail is installed; The parallelism of two rail axis; The parallelism of the slideway of two guide rails; And, the planeness that the rear rail face is installed.Because guide rail is installed on the base platform of autonomous Design and processing usually, thus the parallelism of the slideway of two guide rails, and the planeness that the rear rail face is installed, can require by the Design and Machining that improves the guide rail attachment face to solve.
Guide rail and base platform generally adopt socket head screw to connect.In order not destroy existing precision of guide rail and performance, generally forbid on guide rail, joining and make pin-and-hole.And screw does not possess locating function, and therefore, how guaranteeing or repair the straightness accuracy of the single guide rail installation of accent and the parallelism of two guide rails is difficult points.
In the prior art, for addressing this problem, the measure of being taked mainly comprises 2 points: the structural design of improving the guide rail mounting base; Use external instrument adjustment.
For the structural design of improving the guide rail mounting base, at present the rail mounting structure that adopts is that attachment face with guide rail is designed to right angle type or deep gouge form, improve the planeness that guide rail is installed the face of leaning on and guide rail datum clamp face during design, and the requirement of perpendicularity between the two, and improve the parallelism requirement that two guide rails are installed the face of leaning on.When guide rail is installed, guide rail to be installed by being adjacent on the face by dead at guide rail, the screw of screwing on then can reduce so to a certain extent because the alignment error, the particularly parallelism error of two guide rails that screw hole brings.But because the manufacturability issues of machining error and part itself, the requirement of precision can not be all satisfied in the guide rail installation of guide rail mounting base in the whole dimension scope by face and guide rail datum clamp face, therefore, keep away and repair accent in unavoidably when guide rail is installed, carrying out among a small circle, at this moment just can only use external instrument to solve.
, can measure to the local error (as the guide rail bending) that (perpendicular to the guide rail attachment face) occurs for guide rail Z, then the deviation larger part is increased pad or the solution of scraping guide rail attachment face, and this precision can keep for a long time with dial indicator.For guide rail the machining error of the face of leaning on being installed by the alignment error or the guide rail of face appearance is installed along guide rail, though also can and add pad by scraping solves, but since screw apply be Z to pressure, this direction mainly is a frictional force, less relatively, because of big gap (with respect to required precision) is arranged between screw and the screw, when slide block drive platform moves on guide rail repeatedly, easily cause the lateral movement of guide rail, the precision of original adjustment is lost.
Therefore, needing badly provides a kind of can avoid the guide rail sidesway in the guide rail installation process, and is convenient to adjust in real time precision, simple in structure, easy to use simultaneously, cost of production is low, and the guides with high precision mounting structure of the high-precision requirement can satisfy the guide rail assembling time.
