Description
Фиг.1Figure 1
Изобретение относитс к станкостроению , а именно к оправкам дл креплени тонкостенных заготовок.The invention relates to machine tool industry, namely to mandrels for attaching thin-walled blanks.
Целью изобретени вл етс повышение надежности креплени при шлифовании торцевых поверхностей.The aim of the invention is to increase the reliability of attachment when grinding end surfaces.
На фиг.1 приведена оправка, вид сбоку; на фиг, 2 - разрез А-А на фиг. 1; на фиг. 3 - оправка, вид сверху. Figure 1 shows the mandrel, side view; FIG. 2 is a section AA in FIG. 1; in FIG. 3 - mandrel, top view.
Оправка содержит стаканообразный корпус 1 с отверстием 2 в его днище и канавками 3 на внешних поверхност х корпуса 1, св занных между собой и с отверстием 2. Кроме того, оправка содержит установленный в полости 4 корпуса 1 поршень 5 с коническим нерабочим торцом 6 и сквозным осевым каналом 7, св занным с закрепленным на корпусе 1 штуцером 8 системы подачи среды (на чертеже не показан) иThe mandrel contains a cup-shaped housing 1 with a hole 2 in its bottom and grooves 3 on the outer surfaces of the housing 1, interconnected with the hole 2. In addition, the mandrel contains a piston 5 installed in the cavity 4 of the housing 1 with a conical non-working end 6 and a through an axial channel 7 connected to a nozzle 8 of the medium supply system (not shown) fixed on the housing 1; and
расположенными в сквозных пазах 9 корпуса 1 и взаимодействующими с нерабочим торцом поршн элементами 10 фиксации заготовки 11 по внутренней ее поверхности. В дне корпуса 1 установлена пружина 12 возврата поршн 5,located in the through grooves 9 of the housing 1 and interacting with the non-working end of the piston, the elements 10 for fixing the workpiece 11 on its inner surface. In the bottom of the housing 1 is installed a spring 12 return piston 5,
Оправка работает следующим образом. Заготовку 11 устанавливают на корпус 1 так, чтобы ее дно плотно прижималось к верхнему торцу корпуса 1. Подают среду через штуцер 8 и осевой канал 7 в полость корпуса 1. Поршень 5 перемещаетс вниз и ко-ничесшм торцом 6 давит на элементы 10, перемеща их в радиальном направлении. При этом элементы 10 закрепл ют заготовку 11. Среда по отверстию 2 и канавкам 3 проникает к внутренней поверхности заготовки 11 и охлаждает ее во врем шлифовани , The mandrel works as follows. The blank 11 is mounted on the housing 1 so that its bottom is pressed firmly against the upper end of the housing 1. The medium is fed through the nozzle 8 and the axial channel 7 into the cavity of the housing 1. The piston 5 moves downward and presses the elements 10 by the end face 6, moving them in the radial direction. At the same time, the elements 10 fix the workpiece 11. The medium penetrates the hole 2 and the grooves 3 to the inner surface of the workpiece 11 and cools it during grinding,
