The powerful lathe tool bar of large-scale adjustable antidetonation
Technical field
The utility model relates to a kind of lathe tool bar on the lathe.
Background technology
The processing of large-scale compressor cylinder sleeve internal diameter is one of most important operation in the compressor manufacturing process.This cylinder sleeve degree of depth is many more than 1m, and diameter does not wait from φ 200 ~ φ 600mm.This operation is processed on the C65 heavy-duty engine lathe, and knife bar will produce vibrations when the required knife bar feed degree of depth surpassed 500mm, caused processed inside diameter surface ripple to occur, had had a strong impact on product quality, and its roughness, linearity all do not reach designing requirement.In order to improve crudy, we have taked a lot of measures, as strengthening the knife bar diameter, reduce the lathe rotating speed and the depth of cut, but effect are undesirable.We analyze lever structure, feel only to strengthen the knife bar diameter, no matter how the knife bar diameter are strengthened, but all can not change the clamped part of the knife bar problem low with the intensity of knife bar binding site.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of large-scale adjustable antidetonation powerful lathe tool bar.
The purpose of this utility model is achieved in that the lathe tool bar comprises and the afterbody and the stem of knife rest clamping part, is characterized in that: at lathe tool bar afterbody, facing to the bar surface of lathe cutter platform one side, axially have two grooves by symmetry up and down along bar.
Compared with prior art, the beneficial effects of the utility model are: after the knife bar afterbody has left two grooves, produce a kind of image angle steel, characteristic that T-steel is the same, the shock strength of knife bar is greatly improved, and can in 300~1500mm scope, adjust the use length of cutter hub arbitrarily, when cutting, eliminated vibrations, processed cylinder sleeve surface quality of workpieces is greatly improved.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.

The specific embodiment
The lathe tool bar comprises afterbody 2 and the stem 1 with the knife rest clamping part, at lathe tool bar afterbody, facing to the bar surface of lathe cutter platform one side (left side among Fig. 2), axially has two trough with straight angle 3 by symmetry up and down along bar.
