Description
Technical field
The utility model relates to machine tool field, specifically, is a kind of deflection compensation mechanism of floor-type milling & boring machine ram.
Background technology
For numerical control floor type boring and milling machine, ram is the core component of lathe, and rely on ram that lathe can be made to realize long distance, deep hole machining, the precision of ram will directly determine the horizontal machining accuracy of lathe.Because laterally processing stroke mainly relies on ram to realize, because stroke is large, the length that ram stretches out from main spindle box body is comparatively large, and simultaneously genuine in great owing to talking about, stretching out of large length is that ram very easily deflection deformation occurs, and has a strong impact on the machining accuracy of lathe.
Utility model content
The utility model, for above-mentioned the deficiencies in the prior art, devises a kind of floor-type milling & boring machine ram deflection compensation mechanism.
Floor-type milling & boring machine ram deflection compensation mechanism of the present utility model, comprise ram, in the through hole that described ram upper axial is arranged, pull bar is installed, ram the inner is provided with cylinder body, in cylinder body, piston is installed, pull bar is arranged in the axis hole of cylinder body and piston setting, pull bar the inner is provided with the first hold-down nut, first hold-down nut and piston contact, pull bar outer end is provided with the second hold-down nut, second hold-down nut contacts with ram outer end face, is provided with oil pocket in cylinder body, and oil pocket is connected with oil pump by pipeline.
Preferably, the outer end of described ram through hole is provided with step trough, and the second hold-down nut is positioned at step trough.
Preferably, between described first hold-down nut and piston, elastic washer is installed.
The beneficial effects of the utility model are: ram top is strained by pull bar by floor-type milling & boring machine ram deflection compensation mechanism, avoids ram generation deflection deformation, ensures the linear precision that ram stretches out, thus ensure that the horizontal machining accuracy of lathe.Oil pump promotes piston movement by the hydraulic oil pumped into makes pull bar strain ram, the driving mechanism that oil pump can stretch out with Machine-Tool Control ram links, according to the dynamics of the length adjustment ram tension that ram stretches out, ram can be avoided to strain transition, preventing ram towards oppositely there is deflection deformation, further increasing the horizontal machining accuracy that ram stretches out linear precision and lathe.Second hold-down nut is arranged in the step trough of setting, reduces deflection compensation mechanism to the impact of ram overall volume, also makes pull bar outer end fixing more firm, reduces the length of pull bar, reduce the torque arm length of pull bar tension, reduce the power needed for tensile ties.It is more firm that elastic washer makes the first hold-down nut install, and avoids hard piston directly to contact pushing causing the first hold-down nut surface to deform, and improves the service life of whole mechanism.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of this floor-type milling & boring machine ram deflection compensation mechanism.
Detailed description of the invention
Floor-type milling & boring machine ram deflection compensation mechanism of the present utility model, as shown in Figure 1, comprise ram 1, ram 1 is arranged in the main spindle box body of lathe, can in horizontal slip.
In the through hole that ram 1 upper axial is arranged, pull bar 2 is installed, ram 1 the inner is provided with cylinder body 3, is provided with piston 4 in cylinder body 3, and pull bar 2 is arranged in the axis hole of cylinder body 3 and piston 4 setting, pull bar 2 the inner is provided with the first hold-down nut 5, first hold-down nut 5 and contacts with piston 4.Also elastic washer 9 can be installed additional between first hold-down nut 5 and piston 4.
Pull bar 2 outer end is provided with the second hold-down nut 6, second hold-down nut 6 and contacts with ram 1 outer end face.The outer end of ram 1 through hole can arrange step trough 8, the second hold-down nut 6 can be arranged in step trough 8.
Be provided with oil pocket 7 in cylinder body 3, oil pocket 7 is connected with oil pump by pipeline.The driving mechanism that ram 1 laterally slides all is connected with the control terminal of lathe with oil pump.
Control terminal controls driving mechanism to be made ram 1 stretch out to make, the length that control terminal can stretch out according to ram 1, the amount of the hydraulic oil that control oil pump pumps into, thus the power of control piston pushing drawing rod 2, and then the degrees of tensions controlling pull bar 2.The length finally making ram 1 stretch out is longer, and the degrees of tensions of pull bar 2 is larger, avoids ram 1 to strain deficiency or overtighten, prevents deflection deformation, ensures machining accuracy.
