(54) СОЕДИНИТЕЛЬНЫЙ ЭЛЕМЕНТ(54) CONNECTING ELEMENT

1one

Изобретение относитс к машиностроению и может быть использовано дл установки , фиксации и соединени пакетов тонколистовых деталей.The invention relates to mechanical engineering and can be used to install, fix and connect packages of thin-sheet parts.

По основному авт. св. № 739264, соединительный элемент выполнен в виде стержн с головкой, по длине которого выполнены кольцевые канавки, чередующиес с цилиндрическими по сками. Стержень устанавливаетс в отверсти соедин емых деталей. Кольцевые канавки образуют эксцентричные шейки с плавным переходом к цилиндрическим по скам. На головке и цилиндрических по сках выполнены лыски. При этом диаметры эксцентричных шеек увеличиваютс от диаметра d одного конца до диаметра D другого конца стержн ПЗ.According to the main author. St. No. 739264, the connecting element is designed in the form of a rod with a head, along its length there are annular grooves alternating with cylindrical lines. The rod is installed in the holes of the parts to be joined. The annular grooves form eccentric necks with a smooth transition to cylindrical to scam. On the head and cylindrical in the skies are flats. At the same time, the diameters of the eccentric necks increase from the diameter d of one end to the diameter D of the other end of the rod PZ.

Однако известное устройство не может обеспечить соединение деталей из тонких листов толщиной менее ширины кольцевых канавок и центровку соедин емых деталей большего диаметра отверсти чем диаметр стержн .However, the known device cannot provide for the connection of parts from thin sheets with a thickness less than the width of the annular grooves and the alignment of the joined parts with a larger hole diameter than the diameter of the rod.

Цель изобретени - расширение технологических возможностей.The purpose of the invention is the expansion of technological capabilities.

Это достигаетс тем, что соединительный элемент,- содержащий стержень с головкой, по всей длине которого выполнены кольцевые эксцентричные канавки, чередующиес с цилиндрическими по сками, дополнительно снабжен сменными цилиндрическими прутками , а на цилиндрических по сках стержн выполнены продольные пазы, в которых расположены упом нутые прутки, при этом длина прутка меньше длины стержн на величину двух по сков, а диаметр прутков больше глубины паза в по сках.This is achieved by the fact that the connecting element, which contains a rod with a head, along the entire length of which there are annular eccentric grooves alternating with cylindrical cuts, is additionally equipped with interchangeable cylindrical rods, and longitudinal grooves with mentioned rods, with the length of the rod is less than the length of the rod by the amount of two in the bar, and the diameter of the bars is greater than the depth of the groove in the bar.

На фиг. 1 представлен соединительный элемент, обший вид; на фиг. 2 - сечение А-А на фиг. 1.FIG. 1 shows the connecting element, a general view; in fig. 2 is a section A-A in FIG. one.

Claims

The connecting element consists of a rod 1 with a head 2. On the entire length of the rod there are annular grooves 3 alternating with cylindrical bands 4. The circular grooves form eccentric necks 5 with a smooth transition to cylindrical squares 4. Flatheads are made on the head and cylindrical axes 6. At the same time, the diameters of the eccentric necks increase in the direction from one end of the rod to the other. Longitudinal grooves 7 are made on the generatrix over the shafts in which interchangeable cylindrical rods 8 are installed with a length of less than a bar by two sizes and the depth of the grooves is less than the diameter of the bars. Such a design of the rods ensures twisting only two lines, and the depth of the grooves provides, as it were, an increase in the diameter of the entire assembly. The connecting element is installed in the hole of the connected parts 9. The fixing of the connected parts is carried out as follows. In the flats 6 of the head 2 and the adjacent cylindrical port 4, the keys are set (on hell, not pock, azano) and the head is twisted in a turn

2. Then, depending on the diameter of the holes of the parts to be joined, rods 8 are installed in the slots 7 of the rod 1 and the rod 1 is inserted into the holes of the parts 9 connected to the package of size L and, supporting the head 2 with a key, twisting the last cylindrical section 4 , at that, m L: olts; the parts to be joined can be very small, up to foil thickness f .. 0.05 mm. With the decision of cylindrical 4, disassembly of the connected parts .5 with the element is carried out, after which the connecting element can be used to fix the connected parts of the package of a smaller length, and with a larger or smaller diameter of the holes, for which it is enough to replace the rods 8 with another section size. The use of the proposed device allows for the connection of parts with a thickness less than the length of the groove of the rod, the connection of packages of parts with different hole diameters, an increase in the stiffness of the rod, unification of the assembly operations, Claims of the invention Connecting element according to the author. St. No. 739264, characterized in that, in order to expand technological capabilities, it is provided with cylindrical rods, and longitudinal grooves are made on the cylindrical strips of the rod, in which said rods are located, while the length ---- rod is shorter than the rod by two shafts, and the diameter is greater than the depth of the groove in the sku.
