Description
Technical field
The present invention relates to guideway technical field, particularly a kind of novel straight line skid compound guide rail pair.
Background technology
Along with the fast development of China's economic, mega project as high-speed railway, wind power equipment, domestic large Aircraft Project, aerospace equipment, automobile making equipment and construction machinery production to can realize heavy duty, at a high speed and the heavy digital control machine tool performance requirement of high pulling torque cutting day by day improve.
Guide rail is one of core component of heavy digital control machine tool, and it determines rigidity, precision and the precision stability of heavy digital control machine tool to a great extent.
Execution unit (main spindle box, knife rest, the workbench) weight of heavy digital control machine tool is large, and the exercise performance under the bearing capacity to guide rail and heavily loaded heavy cut is had higher requirement.
At present, heavy machine tool mainly contains rolling guide, rail plate and hydrostatic slideway with guide rail.
Rolling guide is by putting into rolling element between guide and movement parts, and can make the not directly contact of two guide pass matching, thereby there is little, the servo-actuated property of frictional resistance and high-speed motion performance is good, positioning precision and repetitive positioning accuracy advantages of higher, but its its contact stress under case of heavy load is large, vibration resistance, rigidity are poor.
The contact area of rail plate is large, and adopts panel guide rail or plastic-sticking guiding rail more, and bearing capacity is large, vibration resistance, good rigidly, but its sound friction ratio is large, autokinesis is lower, and when low speed, easy " creeping ", easy to wear, the shortcoming that service life is shorter.
Hydrostatic slideway adopts fluid friction, oil film good anti-vibration, but its complex structure, and cost is high, maintenance difficult, thereby fail popularization and application.
Above rail types respectively has pluses and minuses, if use separately rolling guide or rail plate to be all difficult to reach the desirable performance indications of heavy machine tool and required precision.
Summary of the invention
The object of the present invention is to provide a kind of novel straight line skid compound guide rail pair.
The technical scheme that realizes the object of the invention is: a kind of novel straight line skid compound guide rail pair, comprise the guide rail and the slide block that cooperatively interact, and described guide rail is trapezoidal rails, and two sides of trapezoidal rails are spigot surface, and the upper surface of trapezoidal rails is loading end;
The trapezoidal groove that slider bottom setting matches with trapezoidal rails, two sides of trapezoidal groove respectively arrange at least one row cylinder roller row along its length, between the upper surface of slide block trapezoidal groove and the loading end of trapezoidal rails, along rail length direction, guide-soft-band are set.
The present invention compared with prior art, its remarkable advantage is: 1) the novel straight line skid compound guide rail pair of the present invention is to be listed as to coordinate with trapezoidal rails both sides spigot surface by cylindrical roller to form rolling guide-rail pairs, and on the guide-soft-band of slide block groove upper surface and guide rail, loading end laminating forms rail plate pair; In the time of little load running, the rolling guide-rail pairs in the present invention plays main guiding, carrying and Unloading Effect, improves machine tool motion sensitivity, has reduced the response time; When heavy load operation, rail plate plays main carrying effect, by increasing damping between faying face, weakens the Oscillation Amplitude in process, improves vibration resistance; 2) the present invention is applicable to the motion guide rail of heavy digital control machine tool, simple in structure, manufacture craft is good, in heavily loaded heavy cut situation, can have larger bearing capacity and good exercise performance concurrently, and can effectively weaken the vibration producing in process, thereby realize the high speed of heavy machine tool motion guide rail, the instructions for use of high-precision, high vibration resistance; 3) straight line skid compound guide rail pair of the present invention is taken into account the advantage of rolling guide and rail plate, the in the situation that of heavily loaded heavy cut, when ensureing the guiding, positioning precision of motion guide rail and guide rail bearing capacity, can reduce rationally and effectively again the resistance of motion, sensitivity, rigidity and the vibration resistance of motion guide rail are promoted, improve working (machining) efficiency, increased guide rail service life.
