Description

Изобретение относитс к конструкци м устройств дл упрочнени поверхностей отверстий пневмодинамическим методом и может быть использовано .в машиностроительной и других отрасл х промЕдшленности.The invention relates to the design of devices for hardening the surfaces of the holes by the pneumatic dynamic method and can be used in engineering and other industrial sectors.

Известны устройства дл упрочн ющей обработки поверхностей отверстий рабочими телами, содержащие корпус, крышку и сопло дл подачи сжатого воздуха 1.There are known devices for strengthening surface treatment of holes with working bodies, comprising a housing, a cover and a nozzle for supplying compressed air 1.

Недостатком данных устройств вл етс мала эффективность обработки крупноразмерных поверхностей отверст 1й , например диаметром свыше 100 мм, из-за большого объема рабочей кгилеры, необходимой дл упрочнени таких отверстий . Кроме того, дл сохранени потребной скорости сжатого воздуха, разгон ющего тела, требуетс большой расход сжатого воздуха, что затруд н ет использование этого устройства.The disadvantage of these devices is the low processing efficiency of large-size surfaces of the 1st opening, for example, over 100 mm in diameter, due to the large amount of working weight that is required to strengthen such openings. In addition, to maintain the required velocity of the compressed air, the accelerating body, a large flow of compressed air is required, which makes it difficult to use this device.

Цель изобретени - повышение интенсификации процесса обработки.The purpose of the invention is to increase the intensification of the process.

Указанна цель достигаетс тем,. что устройство снабжено дополнительными соплами, а корпус выполнен из двух частей, установленных концентрично , при этом внутренн часть выполнена в виде стакана, установленного с возможностью образовани кольцевой рабочей полости, а дно его св зано с крышкой, причем сопла расположены под углом к оси .This goal is achieved by that the device is equipped with additional nozzles, and the casing is made of two parts mounted concentrically, while the inner part is made in the form of a cup installed to form an annular working cavity, and its bottom is connected to the lid, and the nozzles are angled to the axis.

На фиг. 1 изображено предлагаемое устройство, продольный разрез; на фиг. 2 - то же, вид сбоку; на фиг.З разрез А-А на фиг. 1; на фиг, 4 разрез Б-Б на фиг. 1,FIG. 1 shows the proposed device, a longitudinal section; in fig. 2 - the same, side view; in FIG. 3, section A-A in FIG. one; FIG. 4, section BB, FIG. one,

. Устройство состоит из корпуса 1, выполненного из двух частей, уставов-ч ленных концентрично, при этом внутрен н |Часть выполнена в виде стакана, установленного с возможностью образовани кольцевой рабочей полости, и крьошки 2, зафиксированных друг относительно друга открытыми торцами . .. The device consists of a housing 1, made of two parts, fixed concentrically, with the inner part being made in the form of a glass installed with the possibility of forming an annular working cavity, and a crack 2, fixed relative to each other by open ends. .

Рабочие тела 3 размещают в рабочей полости.The working body 3 is placed in the working cavity.

Claims

On the end parts of the housing 1 and to {the lids 2 there are nozzles 4 and 5 located obliquely 1 and the optimum angle of inclination of 25-35 ° C to the axis of the glass, in front of which are exhaust ports 6 and 7. The fastening of the housing 1 and kraika -2 is carried out 8 and a nut 9 by means of a bracket 10. In the cavity of the housing 1 there is a trap 11 of working bodies, having 30 controlled lever 12, a valve 14 installed on the axis 13 and exhaust channels 15 made in the wall of the trap 11. removing the balls from the trap in any position of the device Last in height limit on inclined partitions 16-17.In the cross section, the juice walls of the body parts have the shape of machined surfaces of the openings. The device works as follows. The housing 1 and the lid 2 are concentrically mounted in the area of the surfaces to be machined. The holes on both sides of the workpiece 18 are fixed with a nut 9. By turning the lever 12, the valve 14 is opened and the working bodies enter the working cavity formed by the walls of the housing 1 parts 18. The flap 14 is closed and compressed air is supplied through the nozzles and 5, which accelerates the working bodies 3, and they hit the edges and the surface of the hole being machined, hardening these elements. At the end of the process open the valve 14 until it stops at the end surface of the hole. Working bodies of this get into a trap, after which the shutter closes and stops the supply of compressed air and removes the device from the abrasive part. The proposed device provides high quality hardening of the internal surfaces of the holes, simply in manufacturing and maintenance. The invention The device for strengthening the surfaces of the holes of the parts by working bodies, comprising a housing, a crest and a nozzle for supplying compressed air, which is equipped with additional nozzles and the body is made of two parts mounted concentrically, while the inner part is made in the form of a glass installed so as to form an annular working cavity, and the bottom of it is mounted with a lid, and the nozzles are angled to the axis of the glass.
