Description

Изобретение относится к оборудованию для вибрационной обработки деталей машин и приборов.The invention relates to equipment for vibration processing of machine parts and devices.

Известна резонансная вибромашина ι с электромагнитным приводом, содержа- 5 щая рабочую массу в виде цилиндрического рабочего контейнера с якорями электромагнитов и реактивную массув виде электромагнитных вибраторов, соединенных между собой посредством Ю тяг. Реактивная масса и контейнер машины связаны между собой комбинированной упругой системой, включающей центральный упругий стержень с регулировочными гайками на концах и 15 резиновые упругие элементы, связанные с неподвижными стойками £1].A resonant vibratory machine ι with an electromagnetic drive is known, containing 5 a working mass in the form of a cylindrical working container with anchors of electromagnets and a reactive mass in the form of electromagnetic vibrators interconnected by means of tie rods. The reactive mass and the container of the machine are interconnected by a combined elastic system, including a central elastic rod with adjusting nuts at the ends and 15 rubber elastic elements connected with the fixed struts £ 1].

Однако данная вибромашина характеризуется отсутствием звукоизоляции,недостаточной ее эксплуатационной надеж-20 ностью, вызванной недостаточной жесткостью реактивной массы и возможностью попадания в рабочие зазоры электромагнитных вибровоэбудителей металлической пыли и стружки, а также рас- 25 положением упругого стержня внутри / контейнера, уменьшающим его полезный объем и исключающим возможность обработки крупногабаритных деталей. Шум, вызываемый работой машины, складывается 30 из шума, издаваемого поверхностью колеблющегося контейнера, зависящего , от амплитуда его колебаний и шума, вызываемого соударяющими телами рабочей среды и деталей.However, this vibrator is characterized by the absence of sound insulation, its insufficient operational reliability, caused by insufficient rigidity of the reactive mass and the possibility of metal dust and chips falling into the working gaps of the electromagnetic vibratory vibrators, as well as by the position of the elastic rod inside / the container, which reduces its useful volume and excluding the possibility of processing large parts. The noise caused by the operation of the machine is composed of 30 of the noise emitted by the surface of the oscillating container, which depends on the amplitude of its vibrations and the noise caused by the impacting bodies of the working medium and parts.

Цель изобретения - снижение уровня шумов, издаваемах контейнером и рабочёй средой, повышение Эксплуатационной надежности машины и увеличение объема контейнера при тех же erb габаритах.The purpose of the invention is to reduce the noise level emitted by the container and the working environment, increase the operational reliability of the machine and increase the volume of the container with the same erb dimensions.

Указанная цель достигается тем, что в двухмассовой резонансной вибромашине с электромагнитным приводом реактивная масса выполнена в виде замкнутого кожуха, к торцам которого присоединены электромагниты вибратора, а контейнер размещен коаксиально внутри реактивной массы.This goal is achieved by the fact that in a two-mass resonant vibratory machine with an electromagnetic drive, the reactive mass is made in the form of a closed casing, the vibrator electromagnets are attached to its ends, and the container is placed coaxially inside the reactive mass.

При этом пространство между кожухом, упругими стержневыми элементами ₍и контейнером заполнено эластичным звукоизолирующим материалом.In this case, the space between the casing, the elastic rod elements ₍ and the container is filled with elastic soundproofing material.

Кроме того,стержневые упругие элементы расположены в кольцевом зазоре, образованном контейнером и кожухом.In addition, the rod elastic elements are located in the annular gap formed by the container and the casing.

На фиг. 1 представлена вибромашина, вид сбоку; на фиг. 2 - разрез А-А на фиг. 1.In FIG. 1 shows a vibrator, side view; in FIG. 2 is a section AA in FIG. 1.

Вибромашина имеет цилиндрический контейнер 1, соединенный упругой системой в виде четырех стержней 2 круглого сечения с двумя корпусами 3 электромагнитов 4 так, что середины стержней прикреплены к контейнеру, а концы - к корпусам электромагнитов. Коаксиально с электромагнитами, содержащими на сердечниках шесть обмоток 5, расположенными с угловым шагом 60°, с кольцевым зазором по отношению к ним на торцах контейнера закреплены ' два кольцевых якоря 6. Корпуса электромагнитов жестко крепятся к торцам цилиндрического кожуха 7, в верхней части которого расположен люк 8 для загрузки и выгрузки деталей. На внутренней поверхности кожуха закреплены перегородки 9, предотвращающие попадание деталей и обрабатывающей среды в пространство между кожухом и контейнером. Машина крепится к неподвижному основанию 10 посредством мягких амортизаторов 11. Корпуса электромагнитов закрыты торцами 12 кожуха.The vibrator has a cylindrical container 1 connected by an elastic system in the form of four rods 2 of circular cross section with two cases 3 of electromagnets 4 so that the midpoints of the rods are attached to the container and the ends to the cases of electromagnets. Coaxially with electromagnets containing six windings 5 on the cores, arranged with an angular pitch of 60 °, with an annular gap with respect to them, two ring anchors are fixed on the ends of the container 6. The electromagnet bodies are rigidly attached to the ends of the cylindrical casing 7, in the upper part of which hatch 8 for loading and unloading parts. Partitions 9 are fixed on the inner surface of the casing to prevent parts and processing medium from entering the space between the casing and the container. The machine is attached to the fixed base 10 by means of soft shock absorbers 11. The electromagnet housings are closed by the ends 12 of the casing.

Расположение стержневых упругих элементов вне контейнера в кольцевом зазоре, образованном последним и кожухом, позволяет увеличить полезный объем контейнера без увеличения габаритов его, а также дает возможность обрабатывать крупногабаритные . дет али.The location of the rod elastic elements outside the container in the annular gap formed by the latter and the casing allows you to increase the useful volume of the container without increasing its dimensions, and also makes it possible to process large ones. det ali.

The implementation of the reactive mass in the form of a closed cylinder having small amplitudes of oscillations and placement inside its working container with intense vibrations sharply reduces the noise caused by these vibrations and the working medium due to absorption by its reactive mass made in the form of a closed casing. The connection of two vibrators with a rigid cylinder increases the operational reliability of the machine and isolates the working gaps of electromagnetic exciters from external media. In addition, the noise level can be reduced by filling the space between the casing and the container elastic by sound-insulating material, such as foam rubber. 3.. / „„ 7 / U X hfl J1 / / Расположение The location of the core elastic elements outside the container in the annular gap formed by the latter and the casing increases the effective volume of the container without increasing its dimensions, and also makes it possible to process large-sized parts.
