Abstract
The invention relates to a sliding saddle and crossbeam structure. The sliding saddle and crossbeam comprises a crossbeam, a sliding saddle and a ram, wherein the sliding saddle is arranged on a Y-axis hollow sliding chute of the crossbeam; the ram is arranged on a Z-axis hollow sliding chute of the sliding saddle. Differing from a structure that a traditional sliding saddle is arranged on one side of the crossbeam, the sliding saddle and crossbeam structure disclosed by the invention has the characteristics that the ram is not of a cantilever structure, so that the ram cannot generate a torsional moment when sliding on the crossbeam (a Y axis), and thus the error of the ram in an X-axis direction is basically eliminated and no compensation of a numerical control system is needed.
Description
Technical field
The present invention is a kind of process equipment saddle beam structure used, and particularly a kind of saddle beam structure being applicable to gantry machining center, belongs to the innovative technology of saddle beam structure.
Background technology
Crossbeam is the main support of the process equipments such as lathe, saddle is provided with ram and spindle unit, very large to the performance impact of whole lathe.Traditional saddle beam structure is the side that saddle is arranged on crossbeam, and main spindle box is cantilever design, moves after the disturbing moment that its gravity produces causes main shaft.In addition, the diverse location that saddle is arranged on crossbeam can cause the sinking deflection of crossbeam diverse location different.In theory, when saddle is arranged on the centre position of crossbeam, the main shaft amount of moving down and after the amount of moving reach maximum.For avoiding crossbeam to produce distortion, usually improved the rigidity of crossbeam by the form of reasonable Arrangement reinforcement, but the processing technology of crossbeam can be caused to become complicated, cost is high.
Summary of the invention
The object of the invention is to overcome above-mentioned shortcoming and a kind of saddle beam structure is provided.Can not produce disturbing moment when the present invention guarantees that ram moves on crossbeam, ram error is in the X-axis direction eliminated substantially, decreases the time of installing floor stringer and charger, improves the kinematic accuracy of ram.
The technical scheme that the present invention realizes above-mentioned purpose employing is: saddle beam structure of the present invention, includes crossbeam, saddle, ram, and wherein saddle is arranged on the Y-axis hollow runner set by crossbeam, and ram is arranged on the Z axis hollow runner set by saddle.
Saddle of the present invention is arranged on the Y-axis hollow runner set by crossbeam; ram is arranged on the structure on the Z axis hollow runner set by saddle; the present invention is different from the structure that traditional saddle is installed on crossbeam side; usual ram is cantilever design, its gravity and add the cutting force in man-hour and can cause crossbeam torsional deflection.Ram of the present invention is not cantilever design, thus can not produce torsional moment when making ram move (Y-axis) on crossbeam, so ram error is in the X-axis direction eliminated substantially.The present invention reduces the time of installing floor stringer and charger, improve the kinematic accuracy of ram.
