Description

Изобретение огносигс  к вспомогательным инструментам и предназначено дл  зажима сверл в патронах црелей и сверлильных станков. Известно приспособление дл  зажима сверл, содержащее ключ, снабженный зубчатой конической нарозкой дл  зацеплени  с конической нарезкой на наружной втулке патрона, втулку с пальцами, установленную на ключе и скобу, шарнирно соединенную с пальцами l. Недостаток этого приспособлени  заключаетс  в том, что наличие заложенного в конструкцию большого люфта между СКОбой и втулкой патрона не обеспечивает надежного удержани  в зацеплении колес зубчатой пары и, как следствие, ведет к снижению надежности закреплени  сверл. . Известно также приспособление дл  зетжима сверл, содержащее ключ, втулку с пальцами и скобу, снабженную эксцеьгри-ковым рычагом, установленным шарнирно и диаметрально противоположно втулке. При режиме или извлечении сверла из , патрона дрели или сверлильного станка рычаг устанавливсютс  в горизонтальное .положение и скоба свободно надеваетс  на внутреннюю втулку патрона. Затем ключ вставл етс  цилини ческим выступом в одно из рашальных отверстий В1 тренней втулки патрона, а эксцентриковый рычаг переводитс  в вертикальное свободным концом вниз положевве оп  зазора между скобой и внутреннее втулкой патрона . Реактивное усилие при вращении ключа передаетс  скобой на внутреннюю втулку патрона f2. Неаосгаток этого приспособлени  заключаетс  в том, что в момент зацеплени  1фо исходит проска;г зывание Ъ зубчатой конической паре, и коитакгируюшие повер сиосгв подвержены быстрсшу износу. Цель изобретени  - упроцеине комструкоии приспособлени . Поставленна  цель достигаетс  тем, что зубчатый сектор ключа выполнен запои лицо с внутренней поверзшостью втулки, The invention is a fire tool for auxiliary tools and is designed to clamp drills in chucks and drilling machines. A device for clamping drills is known, which includes a key provided with a notched conical rim for engaging with a conical thread on the outer sleeve of the chuck, a sleeve with fingers mounted on the key, and a clip hinged to the fingers l. The disadvantage of this device lies in the fact that the presence of a large backlash in the construction between the clutch and the cartridge sleeve does not ensure reliable engagement of the gear pair wheels and, as a result, leads to a decrease in the reliability of fixing the drills. . It is also known to have a tool holder for a drill clamp, containing a key, a sleeve with fingers and a bracket provided with an eccentric lever hinged and diametrically opposite to the sleeve. When the drill is pulled out or removed from the drill chuck or the drilling machine, the lever is set to the horizontal position and the clamp is freely put on the inner sleeve of the chuck. The key is then inserted with a cynical protrusion into one of the rasping holes B1 of the chuck sleeve, and the eccentric lever is transferred to the vertical free end downward position of the gap between the clip and the inner sleeve of the cartridge. The reactive force during rotation of the key is transmitted by the clip to the inner sleeve of the cartridge f2. A non-retractor of this device is that a slip occurs at the moment of engagement of the 1fo, the toothing of the cone-toothed pair and co-tangent turning are subject to rapid wear. The purpose of the invention is upprocein structural devices. The goal is achieved by the fact that the toothed sector of the key is made to fit the face with the internal pin of the sleeve,
