Изобретение относитс  к области металлообработки и может найти применение дл  установки деталей по резьбовому отверстию при их механической обработке.The invention relates to the field of metalworking and can be used to install parts on a threaded hole during their machining.

Известна резьбова  оправ-ка дл  закреплени  деталей по отверстию, состо н1,а  из хвостовика и рабочей части.Known threaded frame for fastening parts along the hole, condition n1, and from the shank and the working part.

Предлагаема  резьбова  оправка отличаетс  от известных тем, что рабоча  часть ее выполнена в виде наклонного к оси хвостовика стержн , на котором нарезана резьба, соосна  этой оси.The proposed threaded mandrel differs from the known ones in that its working part is made in the form of a rod inclined to the axis of the shank, on which the thread is cut, coaxially with this axis.

Така  конструкци  оправки обеспечивает сокращение времени установки и сн ти  детали .This design of the mandrel reduces installation and removal time.

На фиг. 1 изображена предлагаема  оправка; на фиг. 2 - вид по стрелке Л на фиг. 1.FIG. 1 shows the proposed mandrel; in fig. 2 is a view along arrow L in FIG. one.

Оправка представл ет собой хвостовик / и рабочую часть 2.The mandrel is a shank / and a working part 2.

Оправка крепитс  на станке хвостовиком / и имеет торец 5. На рабочей части 2 выполнена резьба Б, предварительно нарезанна  наThe mandrel is fastened on the machine with a shank / and has an end 5. On the working part 2, a thread B is made, previously cut into

всей длине н обточенна  под углом а (не более 8°) к оси хвостовика так, что только на концах рабочей части остались неполные резьбовые витки. Между хвостовиком и рабочейthe entire length n turned at an angle a (not more than 8 °) to the axis of the shank so that only at the ends of the working part there are incomplete threaded turns. Between shank and working

частью выполнена канавка диаметром d и шириной h.the part is made a groove with a diameter d and width h.

Деталь с резьбовым отверстием поворачиваетс  на угол а к оси хвостовика и свободно надеваетс  на резьбовой стержень без завинчивани  н только после упора в торец 3, перпендикул рный оси хвостовика, зат гиваетс  на резьбе. Дл  сн ти  детали достаточно слегка повернуть ее в обратную сторону н перекосить на угол а. Врем  установки н сн ти  детали значительно сокращаетс .The part with the threaded hole is rotated at an angle to the axis of the shank and freely placed on the threaded rod without screwing on only after it stops at the end 3, which is perpendicular to the axis of the shank, tightened on the thread. To remove the part, it is enough to slightly turn it in the opposite direction and skew by an angle a. The installation time for removing parts is greatly shortened.

Предмет изобретени Subject invention

Резьбова  оправка, состо ща  из хвостовика и рабочей части, отличающа с  тем, что, с целью сокращени  времени установки и сн ти  детали, рабоча  часть выполнена в виде наклонного к оси хвостовика стержн , на котором нарезана резьба, соосна  этой оси.A threaded mandrel consisting of a shank and a working part, characterized in that, in order to reduce the time of installation and removal of the part, the working part is made in the form of a rod inclined to the shank axis, on which the thread is cut, coaxially with this axis.
