Description

ла посредством контргайки 14 и регулировочной гайки 15. Подводитс резец 20 на необходимую глубину резани . Включаетс подача охлаждающей жидкости, включаетс вращение детали и продольна подача устройства (оно закреплено на суппорте станка). При этом ручкой 19 с помощью эксцентриков ролики 6 подвод тс к обрабатываемой поверхности. Производитс обработка вала резанием и обкаткой. Ролики 6, обкатыва сь по конической втулке 5, амортизируют за счет гофрированного упругого кольца 4, создава равномерное давление на обрабатываемую поверхность и не вызыва вибрации.la by means of a lock nut 14 and an adjusting nut 15. The cutter 20 is brought to the required cutting depth. The coolant supply is turned on, the part is rotated and the device is fed longitudinally (it is fixed on the machine caliper). In doing so, the handle 19 is guided by eccentrics with the rollers 6 to the surface to be treated. The shaft is machined by cutting and running. The rollers 6, rolling on the conical sleeve 5, are absorbed by the corrugated elastic ring 4, creating a uniform pressure on the surface to be treated and not causing vibration.

По окончании обработки резец 20 отводитс в исходное положение, а ручкой 19 ролики 6 устанавливаютс в нерабочее положение .At the end of processing, the cutter 20 is retracted to its initial position, and the handle 19 sets the rollers 6 to the non-operating position.

В св зи с поглощением энергии гофрированным упругим кольцом снижаетс вибраци , что позвол ет получать обрабатываемую поверхность дев того класса чистоты.In connection with the absorption of energy by a corrugated elastic ring, vibration is reduced, which makes it possible to obtain a surface of treatment of the ninth class of purity.

Claims

1. A device for machining shafts by cutting and running, containing a deforming body located behind the cutting tool, including a housing with a tubular separator installed in it with work elements interacting with a conical surface

bushings, characterized in that, for the purpose of treating shafts of low rigidity and improving the quality of their processing, the support conic sleeve is made split, and a corrugated elastic ring is located between the housing and said sleeve.

2. A device according to claim 1, characterized in that the supporting conical sleeve is made with an oblique cut.
