Description
Technical field
The present invention relates to Longmen machine tool technical field, more particularly to a kind of crossbeam for Heavy Traverse lifting Longmen machine tool
Clamp system.
Background technology
Heavy gantry machine tool processing is applied widely, and working ability is strong, and automaticity is high, is the modern times large-scale, heavy zero
The indispensable universal equipment of part processing.In order to adapt to large-scale part, heavy gantry machine tool size and weight are huge, particularly may be used
The crossbeam of vertical lift and appurtenances length thereon can be more than 10 meters, and weight is to be fixed such as in vertical direction more than 50 tons
This length, the crossbeam of weight, because required clamping force is too big crossbeam and column deformation can be caused excessive, be unfavorable for ensureing under machining state
Crossbeam possess good rigidity, stability and vibration resistance, therefore function need to be set reliable, the small clamping device of pinching deformation is used
Clamped after crossbeam positions on column.
Beam lifting Longmen machine tool machine beam clamping device traditional at present typically has two ways：One kind is slided using in crossbeam
The motion of Hydraulic Cylinder wedge is set on dynamic guide rail, the column guide rail back side is pushed down by wedge ejection, forms column guide rail
Compression；For another kind using the motion of Hydraulic Cylinder wedge is set on crossbeam, it is same that wedge jacks up lever pressing plate drive end
When lever pressing plate compress pressure-bearing surface on machine pillar, crossbeam slide guide rail be pressed on to be formed on column guide rail clamped.This
Two kinds of clamping modes are simple in construction, and adjustment is convenient, and larger thrust can be formed by the boosting function of wedge and lever.But
Be this structure have one it is bigger the shortcomings that：Clamping device relies on thrust between machine tool beam slide guide rail and column guide rail
Realize, the more heavy required thrust of crossbeam is bigger, and the deformation of crossbeam and column is bigger, and lathe resetting will be influenceed by deforming
