Abstract

Изобретение может быть использовано в области неразрушающего контрол , а именно в конструкции пьезоэлектрических преобразователей дл контрол изделий как с плоской, так и с криволинейной поверхностью. Цель изобретени - повышение надежности пьезоэлектрического преобразовател . Дл этого пьезоэлектрический преобразователь, содержащий корпус 1, в котором установлена с возможностью перемещени призма 2 с укрепленными на ней пьезоэлементом 3 и демпфером 4, имеющим резьбовую втулку 5, на которую навинчена гайка 6, штуцер 7, снабжен цангой 8, нажимной втулкой 12 и пружиной 15 сжати . Цанга закреплена на гайке 6, в которой выполнена полость 14, в которой размещена пружина сжати , кинематически св занна с гайкой 6, а по другую сторону - пр моугольные отверсти , а в корпусе 1 выполнена кольцева проточка 17, через которые втулка 12 кинематически св зана с выступами 9 цанги 8 гайки 6 и корпусом 1. 3 ил.The invention can be used in the field of non-destructive testing, namely in the design of piezoelectric transducers for testing products with both flat and curved surfaces. The purpose of the invention is to increase the reliability of the piezoelectric transducer. For this, a piezoelectric transducer comprising a housing 1, in which a prism 2 is mounted with movement with a piezoelectric element 3 mounted on it and a damper 4 having a threaded sleeve 5 on which the nut 6 is screwed, fitting 7, is equipped with a collet 8, a pressure sleeve 12 and a spring 15 squeeze. The collet is fixed to the nut 6, in which a cavity 14 is made, in which a compression spring is placed, kinematically connected to the nut 6, and on the other side - rectangular holes, and in case 1 a ring groove 17 is made, through which the sleeve 12 is kinematically connected with protrusions 9 collet 8 nut 6 and body 1. 3 Il.
