Description

Изобретение относитс к механиче кой обработке металлов, оптического стекла, в частности к патронам дл зажима штучных заготовок. Цепь изобретени - упрощение конструкции путем иного выполнений нажимного элемента. На фиг.1 изображено предлагаемое устройство, поперечное сечение; на фиг.2 - то. же, вид сверху.The invention relates to the machining of metals, optical glass, in particular to chucks for clamping piece blanks. The circuit of the invention is to simplify the design by another implementation of the pressure element. Figure 1 shows the proposed device, the cross section; figure 2 - then. same, top view.

Патрон содержит цангу 1 с прорез ми 2, параллельными продольной оси. На цангу 1 конусом 3 надет нажимной элемент 4, снабжённьй выступами 5, которые вход т в прорези 2 и св заны со ступицей 6, св занной с т гой 7. Цанговый патрон коническим отверстием одет на конус шпиндел 8 и св зан с ним быстросъемной гайкой 9. Изделие обозначено позицией 10. Привод т ги не показан.The cartridge comprises a collet 1 with slots 2 parallel to the longitudinal axis. A collet 4 is fitted on the collet 1 with a cone 3, fitted with lugs 5, which are inserted in slots 2 and connected to the hub 6 connected to the bar 7. The collet chuck is fitted with a cone-hole cone 8 and is connected to it with a quick-release nut 9. The product is indicated by the position 10. The drive gear is not shown.

Патрон работает следующим образом.The cartridge works as follows.

Invention Formula

A collet cartridge containing a slotted collet, a pressure member designed to interact with the collet tabs and a drive train, characterized in that, in order to simplify the design, the pressure member is provided with protrusions located in the slotted collet and a hub, by means of which he is associated with. 3 When moving the rod 7 to the left, the pressure element 4 moves together with it, the protrusions 5 move along the notches 2 of the collet 1. In this case, the collet 1 is clamped and the product 10 is secured. When the movement of the 7 is reversed, the collet opens 4 with the passage of the protrusions 5 through the slot m 2 and the release of the product 10.
