Abstract
The utility model relates to a support rail component for a linear bearing. The support rail component comprises a linear bearing and a linear shaft matched with the linear bearing. The support rail component is characterized in that a V-shaped groove is formed on the top surface of the support rail, the V-shaped groove of the support rail is matched and fastened with the surface of the linear shaft, and the support rail is mutually fastened with the bottom surface of the case through the bottom surface of a bracket; the support rail component also comprises an open linear bearing in contact with the surface of the linear shaft in a sliding way and an open bearing seat corresponding to the open linear bearing, and the open part of the bearing seat is movably matched with the two side walls of the support rail. Because the linear shaft is fixed firmly on the support rail, fluctuation and jump are not easy to happen during linear motion, bending and deformation also do not easily happen to the linear shaft, therefore, jamming and jumping do not easily happen to the open linear bearing, and operation balance can be achieve; especially for a slender shaft, deflection and bending does not happen when the amount of load is increased, thereby ensuring the precision of the linear motion, improving the associated application performance, expanding the associated application range, and further prolonging the overall service life.
Description
Technical field
The utility model relates to a kind of linear bearing straight line motion assembly parts, particularly about a kind of linear bearing straight line motion assembly of being fixed by supporting rail.
Background technique
In the linear bearing straight line motion, the ball on the linear bearing directly contacts with the linear axis straight-line rolling, and the linear axis two ends are fixed on the supporting base.In actual applications, linear axis has only the two ends stationary positioned, and linear axis easily fluctuates and beats when straight line motion, influence operation balance.As there not being other rest under the longer situation of linear axis, yielding at the volley, make linear bearing in major axis, produce clamping stagnation, influence usability and stability.In the heavy load field of employment, easily bend or deflection, straight-line precision of linear bearing and stability are reduced, so not only influence supporting usability but also shortened working life.
Summary of the invention
The technical problems to be solved in the utility model be linear axis with linear bearing in straight line motion contacts, particularly indeformable also the fluctuation beated in the motion of heavy load high-speed straight-line, keep original design accuracy of linear bearing and stability, improve linear bearing working life.
Linear bearing supporting rail assembly, it comprises supporting rail and the linear axis that is mated, and it is characterized in that:
One end face is the supporting rail of V-type groove, combined the tightening up of axial plane of the interior V-type groove of supporting rail and described linear axis, and supporting rail tightens up mutually by the bottom surface and the cabinet bottom surface of support;
One with the opening linear bearing of linear axis axial plane sliding contact and with the corresponding opening shaft bearing of opening linear bearing, the opening portion of bearing support and supporting rail two side activity fit.
The opening linear bearing is to become the opening linear bearing after a raceway position cutting is removed in the general linear bearing, refills to be fitted in the opening shaft bearing.Opening aluminium bearing seat is that the car inner hole surface is milled in the laggard row cutting of aluminum alloy drawing opening section bar, and is corresponding with the breach of opening linear bearing.And bore and attack the installing and locating fixed bolt hole.Linear axis is common shaft and mutually bores the tapping hole across a certain distance and aluminium supporting rail attachment hole connects usefulness on axial same straight line.The aluminum supporting rail is that aluminum alloy is drawn into end face V-type channel section and matches with the linear axis exterior arc surface and to merge by aequilateral stent support on base plate plane, after alignment, be connected and fixed the positioning and fastening of also holing across a certain distance mutually on the both sides, bottom surface with equidistant auger shell keyhole of linear axis and linear axis middle.
Because linear axis fixation on supporting rail, in linear movement, be difficult for producing fluctuation, and linear axis also is difficult for producing bending deflection, makes the opening linear bearing not produce clamping stagnation and jumping phenomena in linear movement, reaches the operation balance, slender axles particularly, also do not produce the deflection buckling phenomenon when increasing capacity value, this has not only guaranteed precision of rectilinear motion, improves supporting usability, enlarge supporting using scope, thereby also prolonged whole service life.
In addition, the straight line motion spare of the steel square linear guide pairs of the low one-level of the also alternative precision of this supporting rail compares in the use, because this project structure is simple, manufacturing process is reasonable, the manufacturing efficiency height, with short production cycle, operating cost is low, is low and middle-grade linear guide pairs alternatives.
