Изобретение относится к машиностроительной и другим металообрабатывающим областям промышленности, использующим вибрационные установки для очистки и отделки поверхностей деталей.The invention relates to mechanical engineering and other metal-processing industries using vibrating installations for cleaning and surface finishing of parts.

По основному авт. св. № 878516 известна вибрационная машина для очистки и отделки поверхностей деталей с использованием охватываемой и охватывающей колеблющихся поверх·* ностей, которые создают встречные подтоки рабочей среды и обрабатываемых деталей (1].According to the main author. St. No. 878516, a vibration machine is known for cleaning and finishing surfaces of parts using covered and enveloping oscillating surfaces · *, which create counterflows of the working medium and workpieces (1].

Целью изобрётения является повышение производительности процессов виброабразивной обработки и расширение ее технологических возможностей. 20The purpose of the invention is to increase the productivity of the processes of vibration-abrasive processing and the expansion of its technological capabilities. 20

Это достигается тем, что в вибрационной машине использован двухвальный двухчастотный вибратор, валы которого расположены относительно охватываемой и охватывающей поверхностей в вертикальной плоскости, что позволяет создать сложную траекторию движения среды со сложным переплетением потоков, рабочей среды, что исключает прилипание деталей к рабочим 30 поверхностям контейнера и друг к Другу и обеспечивает высокую производительность процесса за счет существен_ ного увеличения вибрационного ускаре⁵ ния. .This is achieved by the fact that a two-shaft two-frequency vibrator is used in the vibrating machine, the shafts of which are located relatively to the male and female surfaces in a vertical plane, which allows you to create a complex path of the medium with a complex interweaving of flows, the working medium, which eliminates the adhesion of parts to the working 30 surfaces of the container and to each other and provides high process performance due to a significant increase in vibrational acceleration ⁵ . .

На фиг. 1 показан общий вид вибрационной машины ; на фиг. 2 - разрез А-А фиГ. 1 ; на фиг. 3 - общий характер траектории движения контейне¹⁰ ра.In FIG. 1 shows a general view of a vibrating machine; in FIG. 2 - section aa fiG. 1 ; in FIG. 3 - the general nature of the trajectory of movement of the container ¹⁰ ra.

Вибрационная машина имеет основание 1, установленное на амортизаторах 2, имеющих линейную харакТеристи15 ку жесткости. На основании 1 закреплен электропривод 3, который через гибкую муфту 4 соединен с ведущим валом 5 вибратора, помещенного в контейнере 6 таким образом, что его ось совпадает с продольной осью радиусной части контейнера, Вал 5 вибратора соединен кинематически при помощи повышающей зубчатой передачи 7с вторым валом 8. Оба вала 5 и 8 внутри 25 контейнера закрыты охватываемой (Для рабочей среды) поверхностью .9, выполненной в виде 8 в сечении (см.фйг.2).The vibrating machine has a base 1 mounted on shock absorbers 2 having a linear stiffness characteristic 15. On the base 1, an electric drive 3 is fixed, which is connected through a flexible coupling 4 to the drive shaft 5 of the vibrator placed in the container 6 in such a way that its axis coincides with the longitudinal axis of the radial part of the container, the shaft 5 of the vibrator is connected kinematically by means of an increasing gear 7 with a second shaft 8. Both shafts 5 and 8 inside 25 of the container are covered by a covered (for the working environment) surface .9 made in the form of 8 in cross section (see FIG. 2).

Торцевые стенки 10 и 11 контейнера выполнены наклонными на -угол d внутрь контейнера. Оси валов 5 и б лежат в одной вертикальной плоскости, проходящей через продольнуюось симметрии контейнера, который упруго подвешен на цилиндрических пружинах.The end walls 10 and 11 of the container are made inclined at-angle d into the container. The axis of the shafts 5 and b lie in one vertical plane passing through the longitudinal symmetry of the container, which is resiliently suspended on coil springs.

Валы вибрационной машины получают вращение от электропривода 3 через _ггибкую муфту 4. Повышающая зубчатая ³1ередача 7 выполнена с передаточным отношением не ниже 2:1. Таким образом, скорость вращения вала 8 значительно больше, чем вала 5. Такое расположение валов и их скорости вращения вызывают несимметричную по вертикали сложную траеторию движения контейнера, которая зависит в основном от передаточного отношения.Shafts vibration machine is obtained by rotating the actuator 3 through the flexible coupling 4 _g Raising ³ 1eredacha gear 7 is provided with a gear ratio of at least 2: 1. Thus, the rotation speed of the shaft 8 is much greater than that of the shaft 5. Such an arrangement of the shafts and their rotational speeds cause a vertically asymmetric complex trajectory of movement of the container, which mainly depends on the gear ratio.

Общий характер траектории показан 15 на фиг. 3. Такая траектория исключает прилипание плоских деталей к стенкам и охватываемой поверхности, чему спо-. собствует также форма самой, охватываемой поверхности.Наклон торцевых сте- 20 нок внутрь контейнера исключает прилипание плоских деталей к торцевым стенкам. Размещение внутри контейнера охватываемой: поверхности в виде двух соединенных срезанных цилиндров (в 25 виде 8 ) позволяет создать в рабочей среде четыре зоны со встречными потоками, которые показаны на фиг. 2 стрелками. За счет создания сложных встречных потоков по сечению контей- 3Q нера и сложной несимметричной траектории движения его, за счет возникновения больших вибрационных ускорений, которые достигают 25т30д, где g ,ускорение силы земного притяжения, 35 резко возрастают скорости относительного проскальзывания частиц и деталей.The general nature of the trajectory is shown 15 in FIG. 3. This trajectory eliminates the adhesion of flat parts to the walls and the covered surface, which is possible. The shape of the covered surface itself also prevails. The inclination of the end walls 20 inside the container prevents flat parts from sticking to the end walls. Placing a covered inside container: a surface in the form of two connected cut cylinders (in 25 form 8) allows you to create four zones in the working environment with oncoming flows, which are shown in FIG. 2 arrows. Due to the creation of complex oncoming flows along the container 3Q cross section and a complex asymmetric trajectory of its movement, due to the appearance of large vibrational accelerations, which reach 25t30d, where g, the acceleration of the Earth's gravity, 35, the relative slip speeds of particles and parts sharply increase.

St. No. 878516 is a known spinning machine for cleaning and finishing the surfaces of parts using the covering and covering of the oscillating over the bones, which create counter-flows of the working environment and processing parts til-. The aim of the invention is to increase the productivity of vibroabrasive processing processes and expand its technological capabilities.
