Недостатком является то, что фикса10 ния каретки и поворот упора осуществляется двумя индивидуальными приводами, что не всегда_: обеспечивает точность отмерз.The disadvantage is that the carriage is locked and the stop is rotated by two individual drives, which is not always the case _{: it} ensures frost accuracy.

Известно также устройство для огра- _J5ничения перемещения материала, содержащее приводную каретку, перемещаемую по направляющим и несущую поворотный упор, механизм фиксации каретки в виде колодки, взаимодействующей с одной из _χнаправляющих, стержень, соединенный с рычагами при помощи осей, а с силовым цилиндром - посредством механической связи |21.A device is also known for restricting the movement of material _J5 , comprising a drive carriage moving along the guides and bearing a rotary stop, a carriage fixation mechanism in the form of a block interacting with one of the _χ guides, a rod connected to the levers by means of axes, and with a power cylinder - through mechanical coupling | 21.

Однако, механизм фиксации не может обеспечивать гарантированную точность обработки изделий, так как силовой цилиндр механизма фиксации в рабочем состоянии должен находиться постоянно под давлением и в случае падения давления в период ударных контактов изделий с упором может произойти смещение каретки совместно с упором; данная конструкция не обеспечивает возможность автоматизации процесса установки упора в заданное положвшгё^ при большом ходе каретки упора возникают трудности в эксплуатации, так как приводные рабочие органы - электродвигатель и два пневмоцилиндра, установленные на каретке, требуют дополнительных устройств для обеспечения подвода электроэнергии и сжатого воздуха в любом местонахождении каретки.However, the locking mechanism cannot provide guaranteed accuracy of processing of products, since the power cylinder of the locking mechanism in working condition must be constantly under pressure and in case of pressure drop during shock contact of the products with an emphasis, a carriage displacement together with an emphasis can occur; This design does not provide the possibility of automating the installation of the stop in a predetermined position ^ with a large stroke of the stop carriage, difficulties arise in operation, since the drive working bodies - an electric motor and two pneumatic cylinders mounted on the carriage, require additional devices to ensure the supply of electricity and compressed air in any the location of the carriage.

Устройство работает следующим образом.The device operates as follows.

Поворотный упор 6 с приводной кареткой 5 устанавливают на заданное расстояние от режущего инструмента станка (на 30 чертеже не показано). Для этого подают команду на включение электродвигателя 12, от которого крутящий момент-передается через редуктор 11 шкиву 8, перемещающему трос 7 с закрепленной на 35 нем приводной кареткой 5 до необходимого положения, автоматически контролируемого указателем 14 положения каретки. После чего привод отключается и подается команда на гицродилиндр 30.The pivot stop 6 with the drive carriage 5 is set at a predetermined distance from the cutting tool of the machine (not shown in figure 30). For this, a command is given to turn on the electric motor 12, from which the torque is transmitted through the gearbox 11 to the pulley 8, which moves the cable 7 with the drive carriage 5 mounted on it 35 to the desired position, automatically controlled by the pointer 14 of the carriage position. After that, the drive is turned off and a command is issued to the gitsrodilindr 30.

Шток гидроцилиндра втягивается в крайнее положение, а связанный с ним кривошип 35 совершает сложное движение за счет связи с шатуном 33 и стойкой 34. Ролики 32, охватывающие шатун 33, ⁴⁵ смещают стержень 24 вертикально вниз.The hydraulic cylinder rod is pulled into the extreme position, and the crank 35 connected with it makes a complex movement due to communication with the connecting rod 33 and the strut 34. The rollers 32, covering the connecting rod 33, ^45, displace the rod 24 vertically downward.

В связи с тем, что в стержне 24 имеется овальный паз 23 и между пальцами 28 и крюком 26 имеется определенное расстояние до половины хода штока сило50 вого цилиндра, рычаги 21 и крюк 26 не меняют своего положения, но после прохождения этого участка пути, стержень 24 захватывает ось 22, опускает ее вниз, а рычаги 21 и крюк 26 при этом 55 разводят колодки 15', 16 и прижимают их к направляющим 4. При этом рычаги устанавливаются в горизонтальное положение (фиг. 6). Так как ход рычагов 21 по горизонтали несколько больше общего зазора между колодками 15, 16 и направляющими 4, то происходит незначительное дополнительное сжатие тарельчатых пружин 19, обеспечивающих постоянное усилие прижима колодок 15, 16 к направляющим 4. В момент фиксации приводом каретки 5 палец 28 поворачивает крюк 26, который через общий вал 27 устанавливает поворотный упор 6 на ось подачи материала (см. фиг. 6).Due to the fact that in the rod 24 there is an oval groove 23 and between the fingers 28 and the hook 26 there is a certain distance to half the stroke of the rod of the power cylinder, the levers 21 and hook 26 do not change their position, but after passing this section of the path, the rod 24 captures the axis 22, lowers it down, and the levers 21 and the hook 26 at the same time 55 separate the pads 15 ', 16 and press them to the guides 4. In this case, the levers are installed in a horizontal position (Fig. 6). Since the stroke of the levers 21 horizontally is slightly larger than the total clearance between the pads 15, 16 and the guides 4, there is a slight additional compression of the disk springs 19, providing a constant pressure force of the pads 15, 16 to the guides 4. At the moment of fixing by the drive of the carriage 5, the finger 28 turns a hook 26, which through a common shaft 27 sets a pivot stop 6 on the axis of the material supply (see Fig. 6).

Материал подается до поворотного упора 6 и останавливается.The material is fed to the rotary stop 6 and stops.

При необходимости осуществления мерной резки материала на заготовки и подачи последних за поворотный упор 6, после каждой операции, подается команда на силовой цилиндр 30, шток которого выдвигается неполностью, а на определенное расстояние за счет срабатывания конечного выключателя 36. При этом шатунIf it is necessary to carry out dimensional cutting of the material to the workpieces and feed the latter for the rotary stop 6, after each operation, a command is issued to the power cylinder 30, the rod of which is not fully extended, and to a certain distance due to the operation of the limit switch 36. In this case, the connecting rod

The invention’s chain is an increase in labor productivity. This goal is achieved by the fact that the fixation system is associated with a pivot stop The connection unit means is provided with an additional block, which interacts with another guide and is located coaxially with the block, both of which are spring-loaded relative to the carriage and connected to the levers, and in the rod there is a groove for accommodating the orient. The connection node is made in the form of a hook rigidly connected to a rotary support, and a finger fixed on the rod and interacting with the hook. The mechanical connection is made in the form of a hinged parallelogram, two rollers connected to the rod and covering the parallelogram connecting rod . FIG. 1 shows a device for limiting the movement of a material; Chapter IV of FIG. 2 is a plan view; in fig. 3 - section A-A; in fig. 4 - Bld; in fig. 5 - section bb In the initial position of the levers of the carriage; Fig, 6 - section bb in the working position of the levers of the carriage. The device contains a roller conveyor 1 with non-driven rollers 2 for moving long-length material 3 and installed in the guides 4 drive carriage 5 with a swivel support 6 to limit the movement of material 3. The carriage is driven from cable 7 tensioned between pulleys 8, 9. In this case, the shaft 10 of the pulley 8 is connected through the gearbox 11 to the electric motor 12, and aart the DZ of the pulley 9 is connected to the pointer 14 of the carriage position. In the carriage, a locking mechanism is mounted in the form of coaxially mounted pads 15 and additionally of a plug pad 16. The carriage 5 is fixed with an emphasis 6 in the guides 4 by selecting a gap in between the guides 4 and the pads 15. The pushers 17, which are pressed by the nuts 18 to the cup springs 19, provide a constant clamping force of the pads 15, 16 to the guides 4 on any part of the length, regardless of the possible inclination of the size between the guide. 4 .. Pushers 17 are connected by axles 20 with levers 21 having, in turn, a common axis 22 placed in slot 23 of rod 24 to provide a guaranteed clearance between direction 4 and pads 15, 16 when the driving carriage moves 5. The axes 20 of the pushers 17 of the pads 15, 16 are connected by a tension spring 25. The mechanism for fixing the carriage 5 is connected to the swivel support 6 by means of a hub 26, made in the form of a hook 26 fixed on the shaft 27 of the swivel support 6, with a finger 28, fixed on the stem 24, interacting with the hook 26 when moving PA tsa 28 down. The spring 26 is constantly acting on the hook 26 to keep the pivoting stop 6 in the extreme inoperative position. covering crank 33 pa allogram. The connecting rod 33 is connected to the rack 34 by two cranks 35. If necessary, for the liming of the stroke of the power cylinder-30 rod, the final cutter 36 is inserted into the design. The device works as follows: The rotating stop 6 with the driving carriage 5 is set at a predetermined distance from the cutting tool. machine (not shown), for this command is issued to turn on the electric motor 12, from which the torque is transmitted through the gear 11 to the pulley 8, moving the cable 7 with the water carriage 5 fixed on it; Automatically kontrogafuemogo pointer 14 position of the carriage. After that, the drive is switched off and the command is given to the hydraulic control 30. The hydraulic rod of the hydraulic head is pulled into the extreme position, and the crank 35 connected with it performs a complex color due to the connection with the connecting rod 33 and the strut 34, Rollers 32; covering the rod 33, shift the rod 24 vertgzhalno down. Due to the fact that the rod 24 has an oval groove 23 and between the fingers 28 KptoKOM 26 has a certain distance to half the stroke of the rod of the strong cylinder, the levers 21 and the hook 26 are not in their position, but after passing through this section of the path, the rod 24 grips the axle 22, lowers it inwards, and the levers 21 and the hook 26 at the same time spread out the keys 15; 16 and press them against the guides 4. In this case, the levers are installed in a horizontal position (Fig. 6). Since the movement of the levers 21 horizontally is somewhat larger than the total gap between the interlocks 15, 16 and guides 4, then a slight additional compression of the disc springs 19 takes place, providing a different force for the pads 15, 16 to be clamped to the guides 4. At the time of fixation of the carriage 5 the finger 28 rotates the hook 26, which, via a common shaft 27, installs a pivoting stop 6 on the material feed axis (see FIG. 6). The material is fed to the pivot stop 6 and stops. If it is necessary to carry out dimensional cutting of the material on the workpieces and feed the latter by the rotary abutment 6, after each operation, a comacde is supplied to the power cylinder 30, the rod of which is not fully extended, and by a distance of 1 due to the operation of the end switch 36. 33 performs a limited movement upwards displacing the rod 24 relative to the fixed axis 20 by a distance comparable to the groove cut in the rod 24, the levers 21 remain in a horizontal position, and the drive carriage 5 remains with a fixed about the guides 4. This stroke is enough to turn the croc 26, freed from the finger 28 under the action of the spring 29, which retracts the hinged stop 6 from the feed axis. After displacing the material for the rotary stop 6, it is installed on the feed axis by the reverse stroke of the power rod cylinder. The device allows guaranteed carriage fixation and, therefore, increases accuracy and productivity. Economic efficiency is approximately 25,000 rubles. 5 Claim of the invention 1.
