Изобретение относитс к технолс1гическим средствам машино-и приборостроени .The invention relates to technological means of machine building and instrument making.

По основному asT.cB.lf 602307 известно устройство дл обработки тонкостенных цилиндрических деталей, :одержащее деформатор, выполненный в виде кулачка, установленного на валу задающего устройства и контактирующего через вращающуюс опору с внутренней поверхностью обрабатываемой детали 1 .According to the main asT.cB.lf 602307, a device for processing thin-walled cylindrical parts is known: a stubborn deformer made in the form of a cam mounted on the shaft of the driver and in contact with the inner surface of the workpiece 1 through a rotating support.

Недостатком данного устройства вл етс то, что оно не исключает колебаний детали, и переналадка устройства на другой типоразмер обрабатываемых деталей сложна.The disadvantage of this device is that it does not exclude oscillations of the part, and the changeover of the device to another size of the workpiece is complex.

. Цель изобретени - повышение точности обработки и увеличение производительности .. The purpose of the invention is to improve processing accuracy and increase productivity.

Указанна цель достигаетс тем, что в устройстве дл обработки тонкостенных цилиндрических деталей кулачок выполнен съемным и на его торцеThis goal is achieved by the fact that in the device for processing thin-walled cylindrical parts, the cam is made removable and at its end

выполнены выступы, а на валу - соответствующие им впадины, причем вал выполнен телескопическим, а между ним и кулачком установлена введенна в устройство упруга втулка.the protrusions are made, and the corresponding depressions on the shaft, and the shaft is made telescopic, and an elastic sleeve is inserted between the cam and the cam.

На фиг. 1 схематически представлено предлагаемое устройство, общий вид; на фиг. 2 - сечение А-А на фиг.1.FIG. 1 shows schematically the proposed device, a general view; in fig. 2 is a section A-A in FIG.

Устройство включает задающее устройство 1, деморматор в виде кулач10 ка 2, установленного эксцентрично на валу 3 с помощью упругой втулки4, гайку S с пружинной шайбой 6 и резиновой прокладкой 7. На торцовой поверхности кулачок 2 имеет выступы 8, The device includes a master device 1, a deformer in the form of a cam 10 ka 2 installed eccentrically on the shaft 3 by means of an elastic sleeve 4, a nut S with a spring washer 6 and a rubber gasket 7. On the end surface the cam 2 has lugs 8,

ts вход щие во впадины фланца Э- Кулачок о 2 через вращающуюс опору 10 контактирует с внутренней поверхностью детали 11, обрабатываемой режущим инструментом 12 установленной ts entering the hollows of the flange E-Cam o 2 through the rotating support 10 is in contact with the inner surface of the part 11 processed by the cutting tool 12 installed

30 в приводе 13. Вал 3 выполнен телескопическим .30 in the drive 13. The shaft 3 is made telescopic.

Claims

The device works as follows. The actuator 13 transmits the rotational motion of the part 11 installed on it. The cam 2 mounted on the shaft 3 synchronously with the cutting tool 12, removing the metal layer, performs translational motion along o6 {7 of the machined part 11. According to the signal of the setting device 1, the cam 2 receives a rotational motion. Elastic deformation of the part 11 in the transverse direction occurs, as a result of which the elastic displacements of detali 11 decrease under the action of the radial component P of the cutting force. In order to compensate for the oscillations of part 1 arising under the influence of the variable nature of the cutting force, cam 2 is planted on the shaft 3 through the elastic sleeve 4, and the rotational movement is transmitted through protrusions 8 entering with a gap in the hollows of the flange 9 of shaft 3 the vibration resistance of part 1 occurs due to the fact that part of the energy of the disturbing moment is absorbed by internal friction in the elastic layer and then dissipates into the environment. The application of the proposed device makes it possible to reduce static and dynamic deformations, increase the vibration resistance, improve processing accuracy and productivity. Apparatus of the Invention: A device for processing thin-walled cylindrical parts. According to aut. No. 602307, in order to improve machining accuracy and increase productivity, the cam is made removable and has protrusions on its end, and moreover, the shaft is made telescopic, and between it and the cam is installed inserted into the device elastic sleeve.
