SUMMARY OF THE INVENTION: the cartridge comprises a housing 1, a sleeve 5 mounted on it, a yoke 6 installed in the sleeve, and clamping cams 9 mounted in the radial grooves of the holder, connected to a screw 11. A gap is formed between the conical hole in the sleeve and the conical surface of the holder, in which the cam shoulders are located. The sleeve is rigidly connected to the sleeve by means of locking screws 15, and the sleeve is connected to the body by means of balls 13 and clips, and rubber rings 16 are mounted on it. When the sleeve rotates through the sleeve and the cams, a screw rotates to move them in one direction or another. When they interact with the conical hole in the sleeve, they come together, clamping the tool. When the cam shoulders engage the yoke, they open apart, releasing the tool. 1 s.p. f-ly, 4 ill.

Description

Изобретение относитс к области обработки металлов резанием и может быть использовано на сверлильных станках, дрел х дл креплени осевого инструмента типа сверл, зенкеров и т.п.The invention relates to the field of metal cutting and can be used on drilling machines, drills for attaching an axial tool such as drills, countersinks and the like.

Целью изобретени вл етс упрощение конструкции и повышение удобства эксплуатации патрона.The aim of the invention is to simplify the design and increase the usability of the cartridge.

На фиг. 1 показан патрон, продольный разрез; на фиг.2 - вид по стрелке А на фиг. 1 ; на фиг.З - узел I на фиг. 1; на фиг.4 - сечение G-Б на фиг.1.In FIG. 1 shows a cartridge, a longitudinal section; FIG. 2 is a view along arrow A in FIG. 1 ; on figs - node I in fig. 1; figure 4 - section G-B in figure 1.

Патрон дл креплени осев.ого инструмента содержит корпус 1 с коническим отверстием 2 Дл присоединени к шпинделю :танка или дрели и соосными с ним концен- грично расположенными наружной цилиндрической поверхностью 3 и резьбовымThe chuck for attaching an axial tool comprises a housing 1 with a tapered bore 2 For attaching to the spindle: a tank or drill and with an external cylindrical surface 3 concentric with it and threaded

Между наружной конической поверхностью обоймы 6 и коническим отверстием во втулке 5 образован зазор, в котором расположены заплечики 12 зажимных кулачков. Втулка 5 св зана с корпусом посредством шариков 13, установленных в ее радиальных отверсти х ,, и подпружиненных фиксаторов 14, св занных с радиальными отверсти ми посредством байонетных соединений и консо9. connected by means of protrusions 10 with grooves at the end of a screw 11 installed in a threaded hole of the housing. Between the outer conical surface of the cage 6 and the conical hole in the sleeve 5, a gap is formed in which the shoulders 12 of the clamping cams are located. The sleeve 5 is connected to the housing by means of balls 13 mounted in its radial holes x, and spring-loaded clips 14 connected to the radial holes by means of bayonet connections and

Обойма 6 жестко св зана со втулкой 5 посредством стопорных винтов 15.The yoke 6 is rigidly connected to the sleeve 5 by means of locking screws 15.

В кольцевых канавках на корпусе, рас: положенных в плоскост х, проход щих через оси фиксаторов и стопорных винтов, установлены резиновые кольца 16.In the annular grooves on the housing, races: laid in planes passing through the axis of the retainers and locking screws, rubber rings 16 are mounted.

Патрон работает следующим образом.The cartridge works as follows.

При вращении втулки 5 в ту или другую сторону вместе с ней вращаетс обойма 6 с кулачками 9 и винтом 11. В процессе перемещени винта в корпусе кулачки взаимодействуют или с коническим отверстием во втулке или заплечиками с обоймой, при этом они соответственно сближаютс , зажима инструмент, или развод тс , освобожда его. При необходимости остановить вращающийс патрон рукой резиновые кольца 16 предохран ют ее от повреждени .When the sleeve 5 is rotated in one direction or another, the yoke 6 with the cams 9 and the screw 11 rotates with it. In the process of moving the screw in the casing, the cams either interact with the conical hole in the sleeve or the shoulders with the yoke, while they come closer, clamping the tool, or divorce of the vehicle, releasing it. If it is necessary to stop the rotating cartridge by hand, the rubber rings 16 protect it from damage.
