Изобретение относитс к средствам механизации вспомогательных операций ва металлообрабатывающих станках и может быть использовано на фрезерных, а также и других станках дл креплени инструмента.The invention relates to the mechanization of auxiliary operations in metalworking machines and can be used on milling machines, as well as other machines for fastening tools.
Известны устройства, в которых оправка с инструментом зат гив.аетс в конусе шпиндел штревелем при помощи силовых пружин, а освобождаетс сжатием этих пружин, гидроцилиндром . Однако эти устройства: не обеспечивают надежного креплени инструмента изза недостаточной жесткости зат гивающих инструмент силовых пружин.There are known devices in which a mandrel with a tool is tightened in the spindle taper with a spindle using force springs, and is released by compressing these springs with a hydraulic cylinder. However, these devices: do not provide a reliable fastening of the tool due to the insufficient rigidity of the force springs that tighten the tool.
Предлагаемое устройство отличаетс от известных тем, что па заднем торце щпиндел установлен стакан со смонтированной на нем, взаимодействующей с силовыми пружинами и иеремещаемой порш-нем втулкой с закрепленными попарно сочлененными поворотными рычагами, второй конец которых закреплен на штревеле и вз аимодействует посредством установленных в местах сочленени рычагов роликов с имеющимс , на внутренней поверхности втулки конусом, выполненным самотормоз щим и запирающим ролики под действием силовых пружин после сн ти давлени на порщень.The proposed device differs from the known ones in that the rear end of the pinch assembly is fitted with a cup mounted on it, interacting with power springs and an offset sleeve with a piston fixed in pairs with articulated swivel levers, the second end of which is fixed on the stick and taken by means of mounted in places roller levers with an existing cone made on the inner surface of the sleeve, self-braking and locking the rollers under the action of the power springs after relieving the pressure on porschen.
Такое выполнение устройства позвол ет повысить надежность креплени инструмента.Such an embodiment of the device makes it possible to increase the reliability of fastening the tool.
На чертеже изображено предлагаемое устройство , продольный разрез.The drawing shows the proposed device, a longitudinal section.
Инструмент / зат гиваетс в конусе щпиндел 2 щтревеле.м 8 посредством тарельчатых пружин 4, сжимаемых при освобождении инструмента фланцем втулки 5, смонтированной па закрепленном на торце щпиндел 2 стакане 6 и перемещаемой порщнем 7, размещенным в корпусе 8. На стакане 6 на ос х 9 установлены сочлененные рычаги 10, закрепленные другим концом на ос х //, расположенных на штревеле. В местах сочленени рычагов W на ос х /2 насажены ролики 13, взаимодействующие с конической внутренней поверхностью 14 втулки 5.The tool / is tightened in the cone of the shpindles 2 of the shtrevele.m 8 by means of cup springs 4, compressed when the tool is released by the flange of the sleeve 5 mounted on the shpindles 2 fixed to the cup 6 and movable by means of the 7 placed in the housing 8. On the cup 6 on the x 9, articulated levers 10 are mounted, fastened by the other end to ax x //, located on the stud. In the joints of the levers W on the axis x / 2, the rollers 13 are fitted, interacting with the conical inner surface 14 of the sleeve 5.
Предложенное устройство работает следующим образом. Под действием рабочей среды происходит перемещение порщн 7, сжимающего в начале хода через втулку 5 силовыеThe proposed device operates as follows. Under the action of the working environment, the movement of Porshn 7 occurs, compressing at the beginning of the stroke through the sleeve 5 the power
пружины 4. При дальнейшем перемещении порщн он воздействует на щтревель 3 и выжимает инструмент 1 из конуса щпиндел 2. Производитс замена инструмента. Инструмент зажимаетс силовыми пружинами 4 после сн ти давлени на поршень 7. При этом втулка 5, перемеща сь в исходное положение, наезжает внутренним конусом 14 на ролики 13, зат гивающие посредством рычагов 10 и щтревел 3 инструмент 1 в конусеsprings 4. As the piston moves further, it acts on the chute 3 and squeezes the tool 1 out of the cone of the spindle 2. The tool is replaced. The tool is clamped by the force springs 4 after removing pressure on the piston 7. At the same time, the sleeve 5, moving to the initial position, pushes the inner cone 14 onto the rollers 13, tightened by means of the levers 10 and clicked 3 tool 1 in the cone
