Description
Известны механизмы сдЕига игольницы плоскофанговой машины, снабженные храповым приводом. В них сдвиг игольницы осуществл етс эксцентриком (кулачком), воздействующим на горки, укрепленные на игольнице.Known mechanisms for the needles of a flat-fang machine equipped with a ratchet drive. In them, the needle bar shift is carried out by an eccentric (cam) acting on the slides fixed on the needle bar.
Описываемый механизм отличаетс от известных тем, что, с целью упрощени конструкции, в нем применена бесконечна цепь, составленна из фигурных плашек с впрессованными в них роликами, которые Еоздействуют па горки игольного полотна машины. Цепь получает движение от барабана, установленного на одной оси с храповиком храпового привода.The described mechanism differs from the known ones in that, in order to simplify the construction, it uses an infinite chain made up of figured dies with rollers pressed into them, which are activated on the slides of the needle fabric of the machine. The chain receives movement from the drum mounted on the same axis with the ratchet ratchet drive.
Дл обеспечени сдвига игольницы точно на заданное количество игольных щагов ролики цепи запрессованы в плашках со смещением, кратным игольному шагу машины.To ensure that the needle bar shifts exactly on a given number of needle needles, the chain rollers are pressed in dies with an offset that is a multiple of the needle pitch of the machine.
На фиг. 1 и 2 изображен механизм в двух проекци х.FIG. Figures 1 and 2 depict a mechanism in two projections.
На валу 1, получающем качательное движение, укреплен кривошип 2, щарнирно св занный с рамкой 3. На рамке укреплены пальцы, на которых свободно насажены собачки 4 и 5, прижимаемые к храповику б пружинами 7. Собачки могут быть выключены из зацеплени с храповиком кулачками 8. Храповик жестко укреплен на барабане Р.и вместе с ним свободно вращаетс -на оси 10, закрепленной в корпусе мащины.On shaft 1, which receives a swinging motion, a crank 2 is hinged, hingedly connected to frame 3. The frame is fixed to fingers, on which dogs 4 and 5 are loosely pressed, pressed against ratchet b by springs 7. Dogs can be disengaged from engagement with ratchet by cams 8 The ratchet is rigidly fixed on the drum P. and, together with it, freely rotates on the axis 10, which is fixed in the housing of the machine.
На барабан надета бесконечна цепь //, составленна из фигурных плащек 12 с запрессованными в них роликами 13. РОЛИКИ запрессованы в плашках цепи со смещением, кратным игольному шагу машины. Цепь // получает движение от барабана 9. Дл нат жени цепи слулсит ролик М, который может занимать различное положение в зави.симости от. длины цепи. На планке 15, л естко соединенной с игольным полотном, укрег(лены две горки 16, охватывающие ролики 13 цепи. Пружинный фиксатор J7 служит дл фиксации положени барабана 9 при его повороте .A chain is put on the drum // endlessly composed of figured platens 12 with rollers pressed into them 13. ROLLERS are pressed into chain dies with an offset multiple of the machine's needle pitch. The chain // is driven by the reel 9. For tensioning the chain, the roller M is sled, which can occupy a different position depending on the value of. chain length. On the bar 15, it is firmly connected to the needle web, ukreg (two slides 16, spanning the chain rollers 13. The spring clamp J7 serves to fix the position of the drum 9 when it is rotated.
