По основному авт. св. № 604635 известно устройство дл обработки tO труб на трубообрабатывакнцих станках, содержащее приспособление дл их ;; центрировани относительно шпинделей станков, соединенных с приводом через т гу, рольганг, смонтированный на ра-15 ме, установленный на раме и кинематически св занньлй с приводом ползун и закрепленный на т ге упор, вэаимодейс| вую1цие между собой, причем центрирукадее приспособление установлено 20 под углом к оси шпиндел станка .According to the main author. St. No. 604635, there is known a device for processing tO pipes on pipe-machining machines for knitting machines, containing a device for them ;; centering relative to machine spindles connected to a drive through a th, a roller table mounted on a frame-15, mounted on a frame and kinematically connected to a slide driven and fixed on a t-stop, all-in-one | between each other, with the centrifugal device installed 20 at an angle to the axis of the spindle of the machine.

ОдЬако в таком устройстве не гарантирована точна остановка ползуна, а следовательно не обеспечено центриров .ание трубы.25However, in such a device, an exact stop of the slider is not guaranteed, and therefore the centering of the pipe is not provided.25

Дл повышени надежности в работе, предложенное устройство снабжено средством дл регулировани хода т ги, размещенным между закрепленным на т ге упором и передним торцом ползуна 30In order to increase the reliability in operation, the proposed device is provided with a means for adjusting the thrust, which is placed between the stop fixed on the thrust plate and the front end of the slider 30

Claims

The centering device of the pipe processing machine contains pipe supporting means 1 mounted on frame 2 and pivotally connected by means of levers 3 with a common thrust 4. Th ha 4 consists of intermediate links 5 hinged one over the other. All supporting tools are installed at an angle d- to the axis of the spindle unit of the machine 6. T he 4 by ynojpa 7 is connected to the stem (slide) of the cylinder 8. The stop 7 consists of a nut 9, an outer casing 10 and lock nuts 11. The frame 2 is installed pneumatic cylinders 12 and 13, each connected by means of lugs 14 and axis 15, respectively, to plates 16 and 17. Plates 16 and 17 are swung on axis 18 of bracket 19. Each plastic has a groove 20 for accommodating pulling. The device works as follows; When the pipe is fed into the machine, depending on the length of the pipe, a command is issued to operate either two control cylinders 12 and 13, or one cylinder 8, or no command is received. Accordingly, either the plates 16 and 17, or only the plate 16, or the plates are not inserted at all into the gap between the end of the Cylinder 8 and the stop 7, respectively. Each plate 16 and 17 is inserted by turning it from when water is about axis 18. The plates move in the plane perpendicular to the direction of movement of the rod. A certain set of plates in the gap corresponds to the lifting on the axis of the spindle of the machine 6 of one of the supporting pipe means. .-..- ..,. After being inserted into the gap between the stops 7 and the cylinder In a certain number of plates, the cylinder 8 is actuated and the stop 7 moves to contact either with the plate surface or directly with the end of the front cover of the cylinder 8. At the same time, the end of the pipe 21 reaches the spindle axis machine 6, after which the processing of the pipe. At the end of the treatment, the cylinder rods 8, 12, and 13 are returned to their original position. The adjustment to a different pipe diameter is made by moving the outer ring 10 of the stop 7 along the thread of the nut 9. Formula of the Invention A device for processing pipes on pipe processing machines according to the ed. St. No. 604635, distinguished by the fact that, in order to increase reliability and expand technological capabilities, the device is equipped with a means for controlling the thrust, placed between the stop mounted on the thrust and the front end of the slide, and made in the form of a set of plates, mounted in a plane perpendicular to the axis of the rod.
