The bracket 27 is mounted with the ability to slide onto the frame 1 through the device 28 and the finger 29, which ensures the device is perpendicular to the plane of the blank 30.

Цилиндры 13 шарнирно св заны с балками 11 и 12.Cylinders 13 are articulated with beams 11 and 12.

Вращение на ролики 25 передаетс через редуктор 31 от двигател 26.The rotation to the rollers 25 is transmitted through the gear 31 from the engine 26.

Блок 16 резцов состоит из режущего инструмента 32, цилиндра 33 иThe cutter block 16 consists of a cutting tool 32, a cylinder 33 and

гидравлического мотора }Ц, Инструментальный блок 16 смонтирован сбоку блока роликов на оси 35 и может поворачиватьс дл замены инструмента 32.hydraulic motor} C, The tool block 16 is mounted on the side of the roller block on axis 35 and can be rotated to replace tool 32.

Пола втулка 36 установлена в цилиндре 33. Между цилиндром и втулкой образованы напорные камеры 37 и 38 и имеютс отверсти 39 и 40, св занные с камерами.The floor sleeve 36 is installed in the cylinder 33. Pressure chambers 37 and 38 are formed between the cylinder and the sleeve, and there are openings 39 and 40 associated with the chambers.

Во втулку 36 вставлен вал 41. Инструмент 32 закреплен к одному концу вала, а на другом установлен мотор 34.A shaft 41 is inserted into the sleeve 36. The tool 32 is fixed to one end of the shaft, and the motor 34 is mounted on the other.

При подаче масла из отверсти ЗЭWhen feeding oil from the hole ZE

к камере 37 инструмент движетс к поверхности болва ки, а при подаче масла через отверстие 40 к камере 38 происходит отвод инструмента. В центральной части инструментаto the chamber 37, the tool moves to the surface of the bolt, and when oil is supplied through the opening 40 to the chamber 38, the tool is retracted. In the central part of the instrument

32 предусмотрена впадина 42, так что каждый инструмент может вращатьс , не меша другому.32, a cavity 42 is provided so that each tool can rotate without interfering with another.

Вал 41 может перемещатьс таким образом, чтобь оставатьс перпендикул рным поверхности болванки.The shaft 41 can be moved in such a way as to remain perpendicular to the surface of the blank.

Друга конструкци инструментального блока предусматривает его установку так, что он может качатьс и вал 41 может быть параллелен обрабатываемой болванке. В этом случае инструмент вращаетс при нажиме на обрабатываемую поверхность. Вал 41 может перемещатьс в направлении ширины болванки, так что инструментAnother construction of the tool block provides for its installation so that it can swing and the shaft 41 can be parallel to the workpiece blank. In this case, the tool rotates when it is pressed against the surface to be machined. The shaft 41 can be moved in the width direction of the dummy, so that the tool

может совпасть с трещиной, наход щейс в любом месте по ширине болванки.may coincide with a crack located anywhere along the width of the blank.

Инструментальный блок 16 установлен так, что может качатьс вокруг оси ведущего ролика 24, т.е. качающеес плечо 43 смонтировано на подшипнике 44 снаружи кожуха 45, прикрепленного к раме 46 блока 14 ведущих роликов. Поршень 46 сервоцилиндра 47, один конец которого поворотно поддерживаетс на раме 48, св зан с качающимс плечом 43. Цилиндр 33 прикреплен к переднему концу качающегос плеча 43 параллельно оси вращени ведущего ролика 24. Пола втулка 36, имеюща выпуклость наThe tool unit 16 is mounted so that it can swing around the axis of the drive roller 24, i.e. The rocking arm 43 is mounted on a bearing 44 outside the casing 45 attached to the frame 46 of the block 14 of the drive rollers. The piston 46 of the servo cylinder 47, one end of which is rotatably supported on the frame 48, is connected to the swing arm 43. The cylinder 33 is attached to the front end of the swing arm 43 parallel to the axis of rotation of the driving roller 24. The floor sleeve 36 has a bulge on

Claims

The central part, mounted in cylinder 33, forms pressure chambers 37 YI 38. Pressure ports 39 and 40 5 are associated with the respective chambers. The tool is installed at one end of the shaft}, place the motor 3 at the other end. The device works as follows. Before feeding the devices from the crack detector (not shown), the distance between the beams. 11 and 12 are large enough to allow the blank to pass between the tool blocks, taking into account curvature, deformation, etc. blanks. When the ne, the front end of the billet reaches the roller block after the passage neither through the guide roller 9 nor the lifting cylinders k are lowered by the signal from the detector. At the same time, clamping cylinders 13 were brought into operation in order to fix the blank with the help of leading 25 and driven rollers 26. The grip of the blanks is completed when two clamping cylinders 13 are connected by means of conduit pipes. Then the roller block moves the blank at high speed. When a crack signal is given by the detector, the speed of the blank is set equal to the cutting speed and, depending on the position of the crack, the corresponding tool unit 16 begins to rotate and feed the tool to cut the cracks. When the signal stops, the tool returns to its original position and stops rotating, and the feed of the dummy continues with the roller block. When the rear end of the blanks reaches the roller assembly, the clamping cylinders 13 and the lifting cylinders k are activated by a signal from the detector to free the blanket and set the device to work in the optimum position for receiving the pig. 0 Then the device is prepared to feed the next blank. The proposed device provides the removal of cracks automatically with high efficiency. Apparatus of the Invention A device for mechanically removing and removing stains and cracks from the surface of a workpiece by milling, comprising oppositely located pairs of tool blocks located on both sides of the workpiece, placed on the tool frame with the possibility of vertical movement and installation of the tool to the appropriate machining depth, , in order to automate the process, the device is provided with a fixed frame, with which it is hinged by means of the connected to the horizontal and vertical planes of the power cylinders connected to the instrumental frame, made in the form of beams installed with the ability to move relative to each other, connected by means of additional power cylinders arranged in the device in the vertical plane; moreover, on each beam two instrumental unit at an angle of 90 to each other, and each instrumental unit is equipped with at least one rigidly associated role.
