Автор: Василий Владимирович Пономарев, Виктория Викторовна Сидорова, Михаил Сергеевич Разумов
Принадлежит: Федеральное государственное бюджетное образовательное учреждение высшего образования "Юго-Западный государственный университет" (ЮЗГУ)

Технической задачей данной полезной модели является повышение технологичности устройства для сверления с наложением осевых вибраций и производительности обработки сверлением за счет исключения изгибающего момента, действующего на шпиндель станка и осевыми колебаниями, дискретно-синхронными с частотой вращения шпинделя.Устройство содержит корпус с нижней крышкой, оснащенной постоянными магнитами и верхней крышкой с элементами крепления на станок. Момент вращения с входного вала на выходной передается посредством свободного в осевом направлении шлицевого соединения, одновременно вращение передается на водило планетарной передачи. Осевые вибрации на выходном валу создаются за счет вращения солнечного колеса, в котором также закреплены постоянные магниты, взаимодействие которых с неподвижными магнитами в нижней крышке приводит к возникновению осевых перемещений выходного вала.

Methods suitable for producing textured surfaces in surfaces of objects, by which the methods are able to achieve a desired three-dimensional surface topography and optionally a desired subsurface microstructure through the use of a controlled modulation machining technique. The methods include selecting a predetermined surface texture for a surface of a body, and then imposing a superimposed sinusoidal feed-modulation on a cutting tool so as to move the cutting tool in a feed direction relative to the body while machining the body with the cutting tool and generating a machined surface of the body. The surface texture of the machined surface is intentionally controlled by at least the modulation amplitude and the modulation frequency of the superimposed sinusoidal feed-modulation.

A method for machining a through-hole in a wall of a component, includes setting in rotation on itself a cutting tool about a rotation axis and setting the rotation axis of the tool in rotation about a first orbital rotation axis parallel to, and eccentric by an eccentricity E with respect to, the rotation axis of the tool. The method further includes setting the first orbital rotation axis in rotation, over at least one revolution, about a second orbital rotation axis parallel to, and eccentric by an amount f with respect to, the first orbital rotation axis, the eccentricity being fixed. This configuration makes it possible to balance the elements located between the rotation axis of the tool and the first orbital rotation axis, so that the rotation axis can thus be set in rotation about the first orbital rotation axis at high rotational speeds that contribute toward increasing productivity. 1. A method for machining a through-hole in a wall of a component , comprising:setting in rotation on itself a cutting tool of radius r about a rotation axis,setting said rotation axis of the tool in rotation about a first orbital rotation axis parallel to, and eccentric by an eccentricity E with respect to, the rotation axis of the tool,making the cutting tool and the component effect a movement relative to one another so as to cause the cutting tool to interact with the component in such a way as to obtain a through-hole,withdrawing the cutting tool from the through-hole,wherein in setting the first orbital rotation axis in rotation, over at least one revolution, about a second orbital rotation axis parallel to, and eccentric by an amount f with respect to, the first orbital rotation axis,in using a first intermediate support that allows the cutting tool a rotational movement about its rotation axis and a second intermediate support that allows the first intermediate support a rotational movement about the first orbital rotational axis,the eccentricity (E) between the ...

Methods of ultrasonic drilling for forming perforations in composite materials

Номер: US20210260712A1
Автор: Weidong Song
Принадлежит: Boeing Co

Methods of ultrasonic drilling may be used to form perforated sheets by forming holes through a workpiece using a needle or needle array operatively coupled to an ultrasonic actuator. The needle is brought to repeatedly contact the surface of the workpiece at an ultrasonic operating frequency, thereby forming the hole through the workpiece. Such steps are repeated to form a plurality of holes in the workpiece, thereby forming a perforated sheet which may be used in an acoustic liner for noise attenuation. The workpiece may be heated while the holes are formed, via a remote heating unit that locally heats a portion of the workpiece.
