Description
Изобретение относитс к металлообработке .The invention relates to metal working.
Целью изобретени вл етс улучшение шероховатости обработанной поверхности посредством повышени точности расположени режуш,их элементов за счет повышени жесткости фиксировани винта, регу- лируюш,его положение режущих элементов Б направлении, перпендикул рном его оси.The aim of the invention is to improve the roughness of the treated surface by improving the accuracy of the location of the cutters, their elements by increasing the rigidity of fixing the screw, adjusting its position of the cutting elements B in a direction perpendicular to its axis.
На фиг. 1 показано крепление режущего элемента, разрез; на фиг. 2 - вид А на фиг. 1.FIG. 1 shows the attachment of the cutting element, the cut; in fig. 2 is a view A of FIG. one.
В корпусе 1 режущего инструмента выполнен открытый паз 2 с двум базирующими поверхност ми 3 и 4 под режущий элемент - режущую пластину 5. На винте 6 выполнена коническа поверхность 7 дл взаимодействи с упругим элементом, выполненным в виде щайбы 8 с пружин щим выступом 9. В корпусе 1 в осевом направлении паза 2 выполнен глухой паз 10 дл взаимодействи с выступом 9 шайбы 8. Режуща пластина 5 закрепл етс клином 11.In the cutting tool body 1, an open groove 2 is made with two bases 3 and 4 under the cutting element — a cutting plate 5. On the screw 6, a conical surface 7 is made to interact with an elastic element made in the form of a plate 8 with a spring lug 9. In The housing 1 in the axial direction of the groove 2 is formed with a blind groove 10 for engaging with the protrusion 9 of the washer 8. The cutting plate 5 is fixed with a wedge 11.
При повороте винта 6 пластина 5 перемещаетс в осевом направлении, при этом коническа поверхность винта 6 упираетс в пружин щий выступ 8 и вызывает перекос винта 6 в резьбовом отверстии. Нричем этот перекос за счет взаимодействи пружин щего выступа 8 с пазом Ю происходит в заданном направлении, а именно в осевом направлении паза.When turning the screw 6, the plate 5 moves in the axial direction, while the conical surface of the screw 6 abuts against the spring protrusion 8 and causes the screw 6 to tilt in the threaded hole. This misalignment due to the interaction of the spring protrusion 8 with the groove Yu occurs in a given direction, namely in the axial direction of the groove.
При этом изгибной момент, вызывающий изгиб винта, не возрастает пропорционально осевому перемещению винта (а уменьшаетс ), так как точка приложени изгибающей силы Р приближаетс к точке опоры винта (рассто ние а уменьшаетс ). Нар ду с уменьшением изгиба винта резьбовое отверстие не испытывает нагрузок из-за де- формироваииж винта, так как эти нагрузки воспринимаютс шайбой (в месте контакта винта с отверстием щайбы).In this case, the bending moment causing the screw bend does not increase proportionally to the axial movement of the screw (but decreases), since the point of application of the bending force P approaches the screw point of support (distance a decreases). Along with a decrease in the bend of the screw, the threaded hole does not experience loads due to the deformation of the screw, since these loads are perceived by the washer (at the point of contact of the screw with the hole of the washer).

Кроме того, за счет пружин щего выступа исключаетс возможность раскреплени винта 6 в процессе работы. Нар ду с этим, введение пружин щего выступа обеспечивает значительный ход винта 6, необходимый дл регулировани положени пластин (без существенных его изгибных деформаций, т. е. за счет пружин щего элемента и перемещени точки контакта конической ступени винта с пружин щим выступом щайбы относительно точки контакта винта с отверстием шайбы).In addition, the spring protrusion eliminates the possibility of loosening the screw 6 during operation. In addition, the insertion of the spring protrusion provides a significant movement of the screw 6, necessary for adjusting the position of the plates (without significant bending deformations, i.e. due to the spring element and moving the point of contact of the screw-taper with the spring protrusion of the plate at the point screw contact with the washer hole).
Такое решение позвол ет осуществл ть регулирование положени режущих элементов в щироком диапазоне при одновременно жестком фиксируемом положении винта в процессе работы или при закреплении режущих элементов.This solution allows adjustment of the position of the cutting elements in the wide range while simultaneously holding the fixed position of the screw during operation or when securing the cutting elements.
