Description
Technical field
The invention belongs to the machining technique field, be specifically related to a kind of intermediate strutting device regulated for Super Long-axles processing.
Background technology
The length of 76000 tons of bulk freighter stern tubes has more than 3 meters, need to carry out Boring to its endoporus.The stern tube inner hole precision is related to the installation of oar axle, so extremely important, the circularity behind its bore hole, cylindricity, axiality must reach the related process requirement.The major axis machining apparatus of existing Korea S, boring bar length has reached more than 8 meters, and the diameter of boring bar only has 0.22 meter.So long boring bar will inevitably produce amount of deflection in the fixing situation in two ends, so the tunica process equipment has been equipped with two intermediate bearings, by regulating these two intermediate bearings to eliminate the amount of deflection of boring bar, but still can not reach satisfied processing request, mainly be that the axiality behind the bore hole does not reach requirement.The analysis found that, after boring bar is installed, the amount of deflection direction of boring bar is not unidirectional, mainly be because at the two ends of boring bar except supporting bearing base, it also is equipped with the equipment such as feed gear box, reduction gear box, so, the amount of deflection of boring bar is not the amount of deflection that is simply produced by gravity, the rigid support of multiple spot can produce amount of deflection in any direction, and this direction detection of complex and adjusting are proofreaied and correct also very complicated.The rigidity intermediate bearing that original device adopts is regulated, also can't fundamentally eliminate the amount of deflection that this may produce in any direction, because itself be exactly a rigid support, it is exactly a rigid constraint that increases for boring bar, so only can be so that the deflection deformation of boring bar is more complicated, and can not eliminate.Learn that in first being processed, these 3 of the supporting bearing base at stern tube, boring bar two ends have guaranteed coaxial through overcorrect after further analyzing.So the deflection deformation after boring bar is installed does not affect the axiality behind the bore hole, so can amount of deflection not corrected, that is to say that the intermediate bearing that original device is equipped with can remove.But because the length of boring bar is long, in order to eliminate the deviation of boring bar generation of vibration, this intermediate supports still will be equipped with, so the intermediate supports of this outfit should play the effect of support, guarantee again to make boring bar in the situation that does not increase new rigid constraint, namely rotate processing under the free state.
