Abstract

Изобретение относитс к станкостроению, а конкретно к устройствам дл закреплени заготовок на шпинделе станка. Целью изобретени вл етс повышение точности и надежности закреплени заготовок. В корпусе 1 расположены вставки 2, в пазах которой установлены кулачки 4 с накладками 10. Привод перемещени кулачков - роликово-клиновой от штока 7. В патрон введены средний 14 кронштейн, выполненный в виде двутавра, и крайние 13 - в виде швеллеров, что исключает их пересечение в процессе перемещени кулачков. К одному торцу каждого кронштейна прикреплен кулачок, а к другому - противовес 15. При вращении патрона центробежные силы от кулачков и противовесов замыкаютс на кронштейнах. 4 ил.The invention relates to a machine tool industry, and more particularly to devices for securing blanks on a machine spindle. The aim of the invention is to improve the accuracy and reliability of fixing the blanks. In case 1 there are inserts 2, in the grooves of which cams 4 are installed with overlays 10. The cam movement drive is a roller-wedge from the rod 7. The cartridge has an average 14 bracket made in the form of an I-beam and the extreme 13 in the form of channels, which excludes their intersection in the process of moving the cams. A cam is attached to one end of each bracket, and a counterweight is attached to the other 15. When the cartridge rotates, the centrifugal forces from the cams and counterweights are closed on the brackets. 4 il.

Claims

Claim

To enable crossover <? the location of the brackets 13 and 14 and the elimination of the possibility of their interaction with each other extreme in a row along the axis of the cartridge brackets 13 are made in the form of a channel, and the middle bracket 14 is in the form of an I-beam.

The cartridge works as follows .; With the axial movement of the rod 7 \ the roller mechanism 6 through the protrusion 5 acts on the cam 4, moving * it in the radial direction. Together with the cams 4, counterweights 15 with brackets 13 and 14 move.

A cartridge containing a housing in which cams and associated counterweights are located, characterized in that, in order to increase accuracy and reliability, it is equipped with brackets: middle and extreme, on one end of which each cam is located, and on the other a counterweight · , while the middle bracket is made in the form of an I-beam, and the extreme ones are in the form of channels, moreover, radial grooves are made in the cartridge case, · designed to accommodate counterweights.
