Abstract

Изобретение относитс к металлообработке и может быть использовано при закреплении деталей. Цель изобретени - повышение надежности закреплени посредством обеспечени равномерных усилий закреплени . В пазах корпуса 1 расположены зажимные элементы, выполненные в виде кулачков 2, которые контактируют со скошенными поверхност ми полого толкател 4, контактирующего с гайкой 7 т ги 5. В полости толкател 4 установлена конусна втулка 10, контактирующа с плунжерами 16. На т ге 5 закреплено упорное кольцо 15 и установлена шайба 14, между которыми и торцом полости толкател 4 установлена нажимна пружина 12, а возвратные пружины 8 и 11 и шайбы 9 и 13 расположены между торцами конусной втулки 10 и корпуса 1. При перемещении т ги 5 происходит сначала зажим детали 22 плунжерами 16 и досылка ее до опоры "Г" корпуса 1, а затем и кулачками 2, обеспечива надежное закрепление. 5 ил.This invention relates to metalworking and can be used to fasten parts. The purpose of the invention is to increase the reliability of fastening by providing uniform clamping forces. In the slots of the housing 1 there are clamping elements made in the form of cams 2, which are in contact with the beveled surfaces of a hollow pusher 4 in contact with a nut 7 tons 5. In the cavity of the pusher 4 there is a conical sleeve 10 in contact with the plungers 16. On the bar 5 A retaining ring 15 is fixed and a washer 14 is installed, between which and the end face of the pusher 4 a pressure spring 12 is installed, and the return springs 8 and 11 and washers 9 and 13 are located between the ends of the cone bush 10 and the body 1. When the thrust rod 5 moves, the clamp det Ali 22 plungers 16 and send it to the support "G" of the housing 1, and then the cams 2, providing a secure fit. 5 il.

Claims

Claim

The mandrel contains a series of expandable elements installed in the grooves of the hollow body, made in the form of wedge cams, designed to interact with the bevels of an annular hollow pusher installed in the body cavity, and a pressure element connected to the rod with a flange at the end, intended for interaction with a second row of spring-loaded expandable elements, characterized in that, in order to increase the reliability of fixing, the mandrel is equipped with three washers, two return and bottom pressure springs and a thrust ring fixed to the rod, the second row of expansion elements is made in the form of plungers 15 located in the radial holes made in the follower, and the pressure element is in the form of a conical sleeve with a recess located in the pusher cavity, while one of the washers and the pressure spring are sequentially installed between the thrust ring and the end of the pusher, and the return springs and two other washers are sequentially in alternating order between the ends of the housing, the pusher and the conical sleeve and, and the thrust flange is designed to interact with the end of the pusher.
