Technical Field
The utility model relates to a solve five-axis machine tool of cross slip table because the cantilever leads to flagging mechanism greatly.
Background
At present, the known five-axis machine tool adopting a cross sliding table structure has the phenomenon that the head of the machine tool sags due to the fact that a Y axis is of a cantilever beam structure, the straightness of the Y axis is not controllable, and particularly, the more the Y axis stretches, the more the head of the machine tool sags obviously. And as the machine tool is used, the longer the time, the larger the variation, and the poor accuracy is maintained. At present, a lot of manufacturers compensate the precision through a numerical control system. However, due to large sagging amount and irregular precision change, the numerical control system can only perform partial compensation and cannot meet the requirement, so that the final precision of the machine tool cannot meet the precision requirement standard.
Disclosure of Invention
In order to overcome current five-axis machine tool of cross slip table structure because the cantilever leads to flagging condition greatly, the utility model provides a mechanism, this mechanism is by the stand, the slide, the ram, the headstock, the slider, linear guide rail is constituteed, and wherein the slide front end extends to the stand outside, and the slide extension adopts trapezoidal strengthening rib structure, and the slide extension simultaneously passes through middle square opening, avoids the headstock to reciprocate the space interference district, improves the rigidity that the ram supported. The ram is connected with the sliding seat through 2 or more linear guide rails and a plurality of sliding blocks, the sliding blocks are always kept in the vertical supporting range of the upright column within the working moving range of the ram, the ram is always supported on the linear sliding rails of the upright column, and the mechanism can ensure the linear precision of the Y axis and keep the precision stable.
The utility model provides a technical scheme that its technical problem adopted is: a mechanism for solving sag caused by large cantilever of a five-axis machine tool with a cross sliding table consists of an upright post (1), a sliding seat (2), a ram (3), a spindle box (4), a linear guide rail (6) and a sliding block (5); the front end of the sliding seat (2) extends to the outer side of the upright post (1), the extending part of the sliding seat (2) adopts a trapezoidal reinforcing rib structure, the extending part is not easy to deform, and the supporting rigidity is improved. The extension part of the sliding seat (2) is in a mode of opening a square opening in the middle, the square opening is larger than the appearance of the spindle box (4), and a space interference area of the spindle box (4) in the vertical movement can be avoided, so that the spindle box (4) can move vertically, and the problem that the five-axis machine tool extension sliding seat (2) with a cross sliding table structure can interfere with the spindle box (4) is solved; ram (3) are through linear guide (6) simultaneously, slider (5) are connected on slide (2), linear guide (6) set up to 2 or many, it removes to set up a plurality of sliders (5) cooperation on every linear guide (6), through distributing slider (5) position, in the work migration range of ram (3), keep throughout having slider (5) in the vertical support within range of stand (1), can effectively improve the support rigidity of ram (3), reach the mesh that prevents the cantilever from drooping. Through the structural design that the front end of the sliding seat (2) extends to the outer side of the upright post (1), the supporting length of the ram (3) can be increased, and the length of the cantilever is reduced.
The beneficial effects of the utility model are that, can solve five-axis machine tool of cross slip table structure because the cantilever leads to the flagging problem of lathe head greatly, promote the precision and the stability of using this structure lathe.
