Abstract
Изобретение относитс к области обработки металлов резанием и может быть использовано при расточке глубоких отверстий. Целью изобретени вл етс повышение надежности за счет отключени давлени рабочего агента во врем возникновеют аварийной ситуации . Штуцер 12 центрирующим по ском 13 установлен в дополнительном отверстии,выполненном соосно каналу подвода рабочего агента 10 в коллекторе 9 и поджат пружинами 16, воздействующими на фланец 15. В процессе работы при попадании стружки под коллектор 9 и заклинивании последнего штуцер, удерживаемый шлангом, преодолевает усилие пружин 16 и поворачиваетс вокруг точки Г, при этом центрирующий по сок, установленньй с зазором в отверстии коллектора 9, не преп тствует этому повороту. В результате штуцер 12 освобождаетс от пружин 16 и отдел етс от коллектора 9, что предохран ет его от поломки . 5 11л. иThe invention relates to the field of metal cutting and can be used when bore deep holes. The aim of the invention is to increase reliability by shutting down the pressure of the working agent during an emergency. The nozzle 12 centering along sk 13 is installed in an additional hole made coaxially to the supply channel of the working agent 10 in the manifold 9 and preloaded by the springs 16 acting on the flange 15. During operation, if the chips hit the collector 9 and the last is jammed, the nozzle held by the hose overcomes springs 16 and rotates around point G, while the juice centering on, installed with a gap in the opening of the collector 9, does not prevent this rotation. As a result, fitting 12 is freed from springs 16 and separated from manifold 9, which prevents it from breaking. 5 11l. and
