Abstract

Изобретение относитс к машиностроению и может быть использовано дл соединени двух деталей с секретом. Цель изобретени - расширение области применени и повышение удобства при использовании. В детали 1 выполн ют ступенчатые отверсти . Ступень меньшего диаметра имеет резьбу, одинаковую с резьбой отверстий в базовой детали 2. Шаг резьбы отверсти в присоедин емой детали кроме одного в детали 1, смещен относительно шага резьбы отверстий в базовой детали 2 на величину, не кратную шагу резьбы. Собирают детали при помощи крепежных элементов 3 с утоненным гладким участком. Элементы 3 поочередно завинчиваютс в резьбовые отверсти деталей 1 и 2. При выходе крепежных элементов 3 из резьбовых отверстий детали 1 и входе их в резьбовые отверсти детали 2 деталь 1 автоматически перемещаетс в осевом направлении относительно последней. После поочередного завинчивани крепежных элементов 3 и их дозат жки деталь 1 устанавливаетс в исходное положение и завинчиваетс крепежный элемент 10. При демонтаже соединени вывинчивание крепежных элементов идет в обратном пор дке. 6 ил.The invention relates to mechanical engineering and can be used to connect two parts with a secret. The purpose of the invention is to expand the scope and increase usability. In the part 1, stepped holes are made. The smaller diameter stage has the same thread with the holes in the base part 2. The thread pitch of the hole in the attachment part, except for one in part 1, is offset from the thread pitch of the holes in the base part 2 by an amount that is not a multiple of the thread pitch. Assemble the parts with fasteners 3 with a thinned smooth area. The elements 3 are alternately screwed into the threaded holes of parts 1 and 2. When fasteners 3 come out of the threaded holes of part 1 and enter them into the threaded holes of part 2, the part 1 automatically moves in the axial direction relative to the latter. After alternately tightening the fasteners 3 and metering them, the part 1 is set to its original position and the fastener 10 is screwed in. When disassembling the connection, the fastening elements are unscrewed in the reverse order. 6 Il.

Claims

Claim

A method of connecting parts, in which threaded holes are made in the base part, smooth cylindrical holes are made in the joined part, the joined part is installed on the base until the holes are aligned and threaded elements are screwed into the threaded holes with a smooth section on the head side and a threaded section larger in diameter smooth section, characterized in that, in order to increase the ease of installation while ensuring the secrecy of the dismantling of the connection, the holes in the connected part perform steps and with a step of a smaller diameter on the side of the end facing the base part, and with a thread in it identical to the thread in the base part, and the thread pitch in the holes in the joining part, except one, is offset from the thread pitch of the holes in the base part by an amount not a multiple of the thread pitch, the fastening of the fasteners in the holes with a displaced pitch is carried out all the way into the base part, then they are scrolled to accommodate the threads in the joined and base parts, and the final tightening is performed, after which they are screwed a fastener in a hole made without displacement of the thread pitch.
