Description

Изобретение относитс к обработке металлов резанием и может быть использовано в конструкци х торцовых или пазовых фрез.The invention relates to metal cutting and can be used in the structures of face or grooving cutters.

Известна пазова фреза, содержаща корпус с пазом, расположенным . симметрично его оси, в котором внахлест закреплены имекицие отверсти под крепежные винты в рабочих и вспомогательных част х два одинаковых ножа, сопр женные между собой по плоскости, проход щей через ось паза и передние поверхности режущих элементов, закрепленных в рабочих част х ножей fj .A known groove cutter comprising a housing with a groove located. symmetrically with its axis, in which the overlapping secured the holes for the fastening screws in the working and auxiliary parts are two identical knives that are interconnected along a plane passing through the axis of the groove and the front surfaces of the cutting elements fixed in the working parts of the knives fj.

Недостатком известной езы вл етс сложность конструкции, а также то, что каждый режущий элемент взаимодействует с головкой крепежного винта, е обеспечивающей надежного креплени .A disadvantage of the known Eza is the complexity of the design, as well as the fact that each cutting element interacts with the head of the fastening screw, which does not provide a reliable fastening.

Цель изобретени - повьвление надежности креплени режущих элементов и упрощение конструкции.The purpose of the invention is to increase the reliability of attachment of cutting elements and simplify the design.

Дл достижени поставленной цели в пазовой фрезе, содержащей корпус с пазом, расположенным симметрично его оси, в котором внахлест закреплены имеющие отверсти под крепежные винты в рабочих и вспомогательных част х два одинаковых ножа, сопр женные между собой по плоскости, проход щей через ось паза и передние поверхности режущих элементов, закрепленных в рабочих част х ножей, каждый нож снабжен имеющим отверстие под крепежный винт прихватом, соединенным посредством упругой пepe ttiIЧки со вспомогательной частью и вза10 имодействующим с передней поверхностью режущего элемента, установленного в другом ноже.To achieve this goal, a groove cutter comprising a body with a groove symmetrically located its axis, in which two holes are attached to the fastening screws in the working and auxiliary parts along the plane passing through the axis of the groove and the front surfaces of the cutting elements fixed in the working parts of the knives, each knife is provided with a grip having a hole for the fastening screw, connected by means of an elastic interlock ttiICHki with an auxiliary part and mutually effective with the front surface of the cutting element mounted on another knife.

Отверсти прихвата и вспомогательной части каждого ножа со сто15 роны, противоположной плоскости сопр жени , выполнены коническими под головки крепежных винтов.The holes of the grip and auxiliary part of each knife from the side opposite to the mating plane are made conical for the heads of the fixing screws.

На фиг. 1 показана фреза, общий ВИД} на фиг. 2 - то же, разрез по FIG. 1 shows a milling cutter, a general VIEW} in FIG. 2 - the same section along

20 плоскости, перпендикул рной оси фрезы , проход щей через оси крепежных винтов; на фиг. 3 - то же, разрез по плоскости, параллельной оси фрезы , проход щей через оси крепежных 20 a plane perpendicular to the axis of the cutter passing through the axes of the mounting screws; in fig. 3 - the same, a section along a plane parallel to the axis of the cutter, passing through the axis of the fixing

25 винтов.25 screws.

В корпусе 1 пазовой фрезы симметрично его оси выподнен паз 2, в котором внахлест установлены два одинаковых ножа 3, закрепленные в In the housing 1 of the groove cutter, the groove 2 is symmetrically aligned with its axis, in which two identical knives 3, fixed in

Claims

30 groove screws 4 with conical heads. Each knife has a working part with two holes for screws 4, in the slots of which cutting elements 5 are installed, made, for example, of polycrystals synthetically diamonds, and an auxiliary part 6 with a hole for screw 4, connected by an elastic strip jumper 7 with a clamp 8 in which there is also a hole for the screw 4. Moreover, in the auxiliary part of the knife and the clamp, the holes are tapered under the conical screw heads 4. There is a gasket 9 between the knives. With this design, the knives mounted in the groove of the body securely fasten astringents elements, since the puff screw clamps adjacent to the front surfaces of the cutting elements and press them to the surfaces of the nests. Increased tool rigidity Provides high precision and clean processing. The pressing of the cutting elements with stickings increases the reliability of their fastening, makes it possible for the cutter to work with high cutting speeds and feeds. Claims 1. A groove cutter comprising a housing with a groove symmetrically disposed to its axis, in which the holes for mounting screws in the working and auxiliary parts are fixed with an overlap between two working blades, interconnected along the plane passing through the groove axis and the front the surface of the cutting elements fixed in the working parts of the knives, characterized in that in order to increase the reliability of the attachment of the cutting elements, each knife is provided with a grip screw hole connected by means of ohm elastic jumper with an auxiliary part and interacting with the front surface of the cutting element installed in another knife.

2. The milling cutter according to claim 1, characterized in that, in order to simplify the construction, the sticking holes and the auxiliary part of each knife are from the side opposite to the interface plane, made conical for the heads of the fixing screws.
