Изобретение относитс к металлообработке , а именно к обработке деталей поверхностным пластическим деформированием.The invention relates to metal working, in particular to the processing of parts by surface plastic deformation.

По основному авт. св. № 500048, известна оправка дл алмазного выглаживани деталей, содержаща держатель с алмазным выглаживателем и установленный против него регулируемый упор 1.According to the main author. St. No. 500048, a known mandrel for diamond smoothing of parts, comprising a holder with a diamond smoother and an adjustable stop 1 mounted against it.

Недостатком данной конструкции вл етс то, что упор, прижимаемый к пО верхности обрабатываемой детали, может портить ее. Кроме того, кольцо закрывает зону обработки, что исключает возможность наблюдени за процессом выглаживани .The disadvantage of this design is that the stop, pressed against the surface of the workpiece, can spoil it. In addition, the ring covers the treatment area, which excludes the possibility of monitoring the smoothing process.

Цель изобретени - повышение производительности обработки и улучшение качества обрабатываемой поверхности.The purpose of the invention is to increase the processing performance and improve the quality of the treated surface.

Указанна цель достигаетс тем, что оправка снабжена дополнительным выглаживателем с антивибрационной прокладкой, установленным на регулируемой упоре соосно основному выглаживателю, при этом на кольце, охватывающем обрабатываемую деталь, выполнено окно, предназначенное дл обзора зоны обработки.This goal is achieved by the fact that the mandrel is provided with an additional anti-vibration shimmer mounted on an adjustable stop coaxially with the main smoother, while a window is provided on the ring surrounding the workpiece to view the treatment area.

На чертеже представлена конструкци предлагаемого устройства.The drawing shows the design of the proposed device.

Оправка содержит выглаживатель 1 с упором 2, кольцо (пиноль) 3, охватывающее обрабатываемую деталь 4, пружину 5, держатель 6, руко тку 7, винт 8, перемещающийс при вращении руко тки 7. Пинолькольцо 3 со всеми вхЪд щими в него элементами установлено в корпусе 9 с возможностью возвратно-поступательного пе ,Q ремещени . Упор 2 снабжен выглаживателем 10, который вместе с упором может быть установлен на определенное рассто ние по отношению к обрабатываемой детали 4 и в этом положении контритс гайкой 11. В верхней части в кольце 3 выполнено окно 12, через которое хорошо видно зону обработки - оба выглаживател и обрабатываемую деталь в месте контакта ее поверхности с инструментами. Держатель 6 снабжен упором 13, а пиноль - упоромThe mandrel contains a smoother 1 with an abutment 2, a ring (quill) 3 covering the workpiece 4, a spring 5, a holder 6, a handle 7, a screw 8 moving when the handle 7 is rotated. A pin ring 3 with all the elements inserted into it housing 9 with the possibility of reciprocating ne, Q displacement. The stop 2 is provided with a smoother 10, which together with the stop can be set to a certain distance with respect to the workpiece 4 and in this position with a nut 11. In the upper part in the ring 3 a window 12 is made, through which the treatment area is clearly visible - both are smoothed and the workpiece at the point of contact of its surface with tools. The holder 6 is provided with an emphasis 13, and the quill - an emphasis

Claims

2Q 14, which limit the movement of the holder and the quill holes of windows 15 and 16. There is a window 17 for observing the position of the stop 13 in the housing 9. In order to dampen the vibrations, the smoother 10 is installed through an anti-vibration pad 18. The mandrel works as follows. A mandrel tuned to a certain smoothing force is installed in the tool holder of the lathe so that windows 16 and 17 do not overlap. Next, using a special handle (not shown), press holder 6 with tool 1 out, increasing the distance between the smootheners 1 and 10 a few millimeters in relation to the diameter of the workpiece. In this position, the workpiece 4 is inserted into the ring between the smoothers and secured in the cartridge or in the centers. After that, by turning the special handle, the power spring is put in action, as a result of which the smoothers with a given force act on the treated surface. Include the rotation of the part in the feed. There is a smoothing of the workpiece at the same time by two smoothers. A given smoothing force is created by compressing the spring 5 with a screw 8 for a certain Value. The spring is compressed, acting on the holder 6, presses the smoother 1, to the workpiece, and at the same time with the same force, but in the opposite direction, acting on the screw 8 and further on the ring-quill 3 and the smoother 10, also presses it to the treated surface. During the smoothing of parts having a beating, the spring 5 does not have time to change its position, therefore, only the reciprocating movement of the quill 3 in the body 9 by the amount of this beating occurs. In this case, the equality of the smoothing forces on the smoothers and 10 is maintained. Such a design eliminates the deflection of light-rigid parts, allows for efficient, with greater speed, to process parts that have a beating. The proposed mandrel allows twice the smoothing speed and 1.5 times the feed. The invention of the mandrel for diamond smoothing details on the author. St. No. 500048, characterized in that, in order to improve the Ka4ectBa of the treated surface, it is equipped with an additional anti-vibration smoother installed on the adjustable support coaxially to the main smoother, while on the ring surrounding the workpiece there is a window designed for viewing the treatment area Sources of information taken into account during the examination 1.
