850 34 7 сверления отверстия, воздух под давлением подается в правую полость цилиндра 8. Поршень цилиндра вместе со штоком 7, планкой 9 и клином 6 перемещается влево. До подхода планки 9 к планке 13 рейка 5 удерживается на месте пружиной 12 через планку 10. С подходом планки 9 к планке 13 начинается перемещение влево рейки 5, вращение шестерни 15 и перемещение рейки 14 вниз, к этому времени клин 6 выйдет из под рейки 14. Вместе с рейкой 14 опускается обработанная деталь850 34 7 drilling holes, air under pressure is supplied to the right cavity of the cylinder 8. The piston of the cylinder together with the rod 7, strap 9 and the wedge 6 moves to the left. Before the strip 9 approaches the strip 13, the rail 5 is held in place by a spring 12 through the bar 10. With the approach of the bar 9 to the bar 13, the rack 5 is moved to the left, the gear 15 is rotated and the rack 14 is moved down, by which time the wedge 6 will come out from under the rack 14 . Together with the rail 14, the machined part is lowered

18. Деталь снимается с пальцев 16 и на ее место устанавливается новая, необработанная деталь.18. The part is removed from fingers 16 and a new, untreated part is installed in its place.

Воздух подается в левую полость цилиндра. Вправо перемещается поршень со штоком и клином 6, а также рейка 5 от воздействия на нее пружины 12. Поворачивается шестерня 15, перемещается рейка 14 с установленной на пальцах 16 деталью 18. Деталь отверстиями находит на два пальца 3 и упором 17 поджимается к базовой планке 4. Подъем детали 18, установка ее на пальцы и предварительный прижим к базовой йланке производится под действием пружины с ее усилием. Опасность травмирования рабочего исключается . С подходом обрабатываемой детали к базовой планке движение реек 5 и 14 прекращается, а клин 6 под действием пневмоцилиндра продолжает перемещаться в пазу рейки 5 до контакта скошенной поверхностью с поверхностью торца рейки 14. Рейка заклинивается, поджим детали 18 к базовой поверхности планки 4 усиливается, Угол наклона рабочей по верхности клина выбран таким, что отход рейки 14 вместе с обрабатываемой деталью 18 от базовой поверхности от сил резания и подачи исключается.Air is supplied to the left cavity of the cylinder. The piston with the rod and the wedge 6 moves to the right, as well as the rack 5 from the action of the spring 12. The gear 15 is rotated, the rack 14 is moved with the part 18 mounted on the fingers 16. The part finds holes on two fingers 3 and the stop 17 is pressed against the base plate 4 . Lifting the part 18, installing it on the fingers and preliminary clamping to the base yank is performed under the action of a spring with its force. The risk of injury to the worker is excluded. With the approach of the workpiece to the base plate, the movement of the rails 5 and 14 stops, and the wedge 6 under the action of the pneumatic cylinder continues to move into the groove of the rail 5 until the mowed surface contacts the surface of the end face of the rail 14. The rail is jammed, the pressing of the part 18 to the base surface of the bar 4 is enhanced, the angle the inclination of the working surface of the wedge is selected so that the departure of the rail 14 together with the workpiece 18 from the base surface from the cutting and feeding forces is excluded.

Использование зажимного устройства предлагаемой конструкции в станочных приспособлениях обеспечивает надежное крепление обрабатываемых деталей и безопасность работы. Безопасность работы обеспечивается тем, что движение открытой рейки с установленной на ней обрабатываемой деталью производится с усилием пружины. Размещение клина усиливающего механизма в пазу приводной рейки делает конструкцию компактной.The use of the clamping device of the proposed design in machine tools provides reliable fastening of the workpieces and safe operation. Work safety is ensured by the fact that the movement of an open rail with a workpiece mounted on it is made with spring force. Placing the wedge of the reinforcing mechanism in the groove of the drive rail makes the design compact.

Claims

The invention relates to a clamping machine; devices for the securing of parts driven by mechanical processing. It is known a clamping device, in the case of which a support is placed, which is nematically connected to the drive by means of a rail and gear 11. The disadvantage of this device is low productivity, since the drive is made by hand. The purpose of the invention is to improve performance while simplifying the design. This goal is achieved by the fact that the device is equipped with a wedge-shaped wedge in the rail, which is spring-loaded relative to it and installed with the possibility of interaction with the said drive and support. . Fig, 1 shows the proposed device, a general view in section; in fig. 2 shows section A-A in FIG. 1. The clamping device comprises a housing 1, to the upper end of which a conductor plate 2 is attached with base fingers 3 and a strip 4. There is a marking on the slot of the lower part of the housing on the drive rail 5. In the slot of the rail parallel to the direction of its movement, with the possibility of return - wedge 6 is divided by wedge 6 The wedge is pivotally connected to the rod 7 of the pneumatic and cylinder 8, the bar 9 is attached to the butt of the wedge, and the bar 10 to the bar end. The spring of the slats of the round form is inserted into the slot of the 11th spring. squeeze. A strap 13 is attached to the left end of the rail 5. The rail 14 is seated in an inclined housing opening with the possibility of reciprocating motion. The lower end of the rail 14, which is included in the through groove of the rail 5, has a wedge surface, the cat in working position contacts the surface of the wedge 6, the rail 5 and 14 are linked to gear 15, the upper rail of the rail 14 has the shape (1 panel). two fingers 16 and an anvil 17 for presetting the workpiece 18, the latch 19 orients the rail 14 in an angular position. The device works as follows: The workpiece is mounted on the pins 3 and pressed against the base bar 4. After processing, for example, drilling a hole, air pressure is fed into the right cavity of the cylinder 8. The cylinder cylinder, together with the rod 7, the bar 9 and the wedge 6 is moved left. Before the bar approaches the bar 13, the bar 5 is held in place by the spring 12 through the bar 10. With the bar 9 approaching the pdank 13, left shift of the rail to the left of the rail 5, rotation of the gear 15 and movement of the rail 14 down, to THIS time the wedge b will come out from under the rail 14, along with rail 14 the processed part 18 is lowered. The part is removed from the fingers 16 and a new one is installed in its place raw detzhsh. Air flows into the left cavity of the cylinder. The piston with the rod and the wedge 6 moves to the right, as well as the rail 5 from the impact of the spring 1. The gear 15 rotates, the rail 14 moves with the piece 18 mounted on the pins 16. The part finds two holes 3 on the holes and the abutment 17 presses against the base bar 4. The lifting of the part 18, its installation on the fingers and the preliminary pressing to the base bar is effected by the force of a spring. The risk of injury to the worker is excluded. With the approach of the workpiece to the base plate, the movement of the rails 5 and 14 is stopped, and the wedge 6 under the action of the pneumatic cylinder continues to move in the groove of the rail 5 until it touches the surface with the end surface of the rail 14. The rail is wedged and the workpiece 18 is pressed to the base surface of the bar 4. The angle of inclination of the working surface of the wedge is chosen so that the withdrawal of the rail 14 together with the workpiece 18 from the base surface from the cutting and feed forces is excluded. The use of the clamping device of the proposed design in machine tools ensures reliable fastening of the workpieces and safe operation. Safety of work is ensured by the fact that the movement of the open rail with the surrounding part is produced with the spring force. Placing the wedge of the mounting mechanism in the groove of the drive rail makes the design compact. Claims A clamping device in which case there is a support is kinematically connected to the drive by means of rack and gear, which is characterized by the fact that the device is equipped with a wedge located in the rack made in order to increase productivity. which is spring-loaded relative to it and installed with the possibility of interaction with the said drive and support.
