Изобретение относитс к установкам дл очистки магоин и может быть использовано на предпри ти х машиностроительной промышленности и на ремонтных предпри ти х.The invention relates to magoin purification plants and can be used in enterprises of the machine-building industry and repair facilities.

Известна установка дл струйной очистки изделий, содержаща рабочую камеру со столом дл размев1ени изделий , сопло дл подвода моющей жидкоеТи с приводом.дл его перемещени относительно очищаемой поверхности, насос и копирную систему регулировани рассто ни от сопла др очищаемой поверхности 1.A well-known device for blasting products containing a working chamber with a table for spreading products, a nozzle for supplying washing liquid with a drive to move it relative to the surface to be cleaned, a pump and a copying system for adjusting the distance from the nozzle to the surface being cleaned 1.

Однако качество очистки криволиней фх поверхностей на данном устройстве невысокое, так как не обеспечиваетс автоматическое поддержание рассто ни от сопла до очищаемой поверхности.However, the quality of cleaning by curviline FX surfaces on this device is low, since it does not automatically maintain the distance from the nozzle to the surface being cleaned.

Цель изобретени - повышение качества очистки изделий, имеющих криволинейные поверхности.The purpose of the invention is to improve the quality of cleaning products with curved surfaces.

Поставленна цель достигаетс тем, что система регулировани рассто ни от сопла дд очищаемой поверхности содержит св занный с соплом пневмопривод через дроссель, соединенный с источником сжатого воздуха, золотниковый соленоидный распределитель, сое .диненный с пневмоприводом, при этом The goal is achieved by the fact that the system for regulating the distance from the nozzle dd of the surface to be cleaned contains a pneumatic actuator connected to the nozzle via a throttle connected to a source of compressed air, a spool solenoid valve connected to the pneumatic actuator.

один из выводов соленоида ,ерез реостат соединен с рабочей камерой, другой с одним из полюсов источника тока второй полюс которого соединен с соплом , а сопло электроизолировано от рабочей камеры и подпружинено в направлении к рабочей повеохности.one of the solenoid pins is connected to the working chamber through a resistor, the other is connected to one of the poles of the current source, the second pole of which is connected to the nozzle, and the nozzle is electrically insulated from the working chamber and is spring-loaded in the direction of the working beam.

На фиг. 1 представлена установка,общий вид; на фиг. 2-то же,вид сверху; н фиг.3 - принципиальна схема системы регулировани рассто ни от сопла до очищаемой поверхности.FIG. 1 shows the installation, general view; in fig. 2 is the same, top view; 3 is a schematic diagram of a system for adjusting the distance from the nozzle to the surface being cleaned.

Claims

The installation consists of a working chamber 1 with a table 2 for placing the product, kinematically connected with the drive 3 of its rotation. In the vertical groove 4 of the wall of the working chamber 1 a carriage 5 is installed, made of electrically insulating material, on which is placed a nozzle 6 for supplying washing fluid with a spring 7 and a pneumatic actuator 8. Soyllo 6 is electrically insulated from. working chamber 1. The carriage 5 is connected by a flexible coupling 9 through the pulley 10 and gear 11 with a gear rack 12 mounted on: the table

2. On the wall of the working chamber 1, the end switches 13 are located at the ends of the groove 4. The pneumatic actuator 8 is connected via a choke 14 to a compressed air source and a spool solenoid valve 15, the spool 16, which is connected to its extension spring 17. The output 18 of the core coil through, the adjusting rheostat 19 is connected to the working chamber 1, and the other output to one of the poles of the current source 20, the other pole of which. pogo connected to nozzle b. The installation works as follows. The product table 2 is rotated by the drive 3, and, through the nozzle 6, the surface of the product around it is flushed with a stream of liquid mocadas. Periodically, for each revolution of the gear table, the rack 12 engages with gear 11, which is rotated at a certain angle with the help of the pulley 10, moves the carriage 56 by the nozzle 6 to the width of the fluid stream, which ensures cleaning the entire surface of the product. The carriage return 5 from the extreme upper and lower positions is performed by reversing the rotation of the table 2c with the limit switches 13. The operation of the distance control system from the nozzle tip to the surface of the product is based on the electrical resistance of the jets of the liquid KocfK jets depending on its length and the change in resistance of the jet is controlled The main signal of the core of the spool solenoid distributor is $ 1 and its spool 16. With the help of a rheostat 19, the spool 16 is set to the position corresponding to nnogo mu air flow, thus in pneumonia moprivode 8 is generated and the excess ement and it against the force pruzhi us 7 together with the nozzle 6 takes the corresponding, relative to the surface being cleaned article position. When changing the jet length in the pro-. During the process of moving the product, the electrical resistance of the jet also changes, which leads to an imbalance of the spool 16, as a result of which the output section of the pneumatic system changes and the nozzle b under the action of the pneumatic actuator 8 or the spring 7 is displaced to rest a broken stream length. An apparatus for blasting products containing a working chamber with a table for positioning products, a nozzle for supplying liquid with its movement relative to the surface to be cleaned, a pump, and a system for adjusting the distance from the nozzle to the surface being cleaned. improve the quality of cleaning products with curved surfaces. The system for regulating the distance from the nozzle to the surface being cleaned contains a pneumatic actuator connected to the nozzle via a choke connected to a source of compressed air, a spool solenoid valve, D 93 NY | with a pneumatic actuator, with one of the solenoid OUTPUTs connected via a rheostat to the working chamber, the other to one of the poles of the current source, the second pole of which is connected to the nozzle, and the nozzle is isolated from the working chamber | l and podpruzhinno in the direction of the working surface ..
