Abstract
The utility model discloses a honeycomb repair threaded connecting assembly with controllable pre-tightening force. The honeycomb repair threaded connecting assembly with the controllable pre-tightening force comprises a weight-loss bolt (1) and a controllable pre-tightening force nut (2). Firstly, the weight-loss bolt (1) penetrates through a honeycomb hole (14) to be repaired, then the controllable pre-tightening force nut (2) is installed, a hexagon head (11) of the controllable pre-tightening force nut (2) is twisted through a hexagon wrench in a wrenching mode until the hexagon head (11) is twisted off from a broken-neck groove (10), and thus a preset mounting pre-tightening force value can be achieved. The honeycomb repair threaded connecting assembly with the controllable pre-tightening force has the advantages of not only reducing the total mass of a connecting part, but also meeting the strict requirement for the beautiful appearance, and being controllable in pre-tightening force, high in safe reliability and convenient to maintain, and is an optimal professional repair threaded connecting assembly in the honeycomb repair field.
Description
Technical field
The utility model relates to a kind of controlled pretightening force honeycomb and repairs screwed assembly, belongs to the fastening connection piece technical field.
Background technique
In the airplane parts design, high-end fastener technology requirement is high, safety reliability is good, expensive.Special the most frequently used method is exactly that conventional bolt and nut is fastenedly connected at some the soft material positions that need repair, though such link is simple in structure, just is not best for the soft material position of this moment.A series of problem concentrated reflections such as outward appearance is not beautiful, and weight is big, and pretightening force is uncontrollable.And for example repair the field at honeycomb, the plain bolt nut connects then can't reach requirement.
Therefore, need a kind of controlled pretightening force honeycomb that can solve an above-mentioned difficult problem badly and repair screwed assembly.
The model utility content
The purpose of this utility model is to provide a kind of controlled pretightening force honeycomb to repair screwed assembly, can solve the positive mechanical connectivity problem that honeycomb is repaired the field, can reduce gross mass, can obtain strict beautiful appearance requirement again, realizes that pretightening force is controlled.
The purpose of this utility model is achieved through the following technical solutions: a kind of controlled pretightening force honeycomb is repaired screwed assembly, it comprises loss of weight bolt and controlled pretightening force nut, wherein, the loss of weight bolt is made up of the bar that reduces that an end has balancing stand, the balancing stand arranged outside has wide-angle countersunk head A, reduce in the other end inner chamber of bar and be provided with interior mounting hole, outer surface is provided with outside thread, controlled pretightening force nut is made up of the bearing partition of band wide-angle countersunk head B and the hexagon head of band cut-off neck slot, be provided with endoporus in bearing partition and the hexagon head inner chamber, endoporus is through hole, endoporus is provided with the internal thread that cooperates with outside thread a section of corresponding bearing partition, and wide-angle countersunk head B links to each other with cut-off neck slot.
Mounting hole and endoporus are inner hexagonal hole in described.
The angle of described wide-angle countersunk head A and wide-angle countersunk head B is 120 °～170 °.
The beneficial effects of the utility model are: the gross mass that has both reduced link, satisfied strict beautiful appearance requirement again, and pretightening force is controlled, and has safety reliability height, characteristics easy to maintenance, is that the best specialty that honeycomb is repaired the field is repaired screwed assembly.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of loss of weight bolt;
Fig. 3 is the structural representation of controlled pretightening force nut;
Fig. 4 is use schematic representation of the present utility model.
Wherein, 1-loss of weight bolt, the controlled pretightening force nut of 2-, 3-wide-angle countersunk head A, 4-balancing stand, 5-reduces bar, hexagonal in the 6-outside thread, 7-, 8-bearing partition, 9-wide-angle countersunk head B, the 10-cut-off neck slot, 11-hexagon head, 12-internal thread, 13-endoporus, 14-honeycomb to be repaired.
Embodiment
Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but that claimed scope is not limited to is described.
As Fig. 1, a kind of controlled pretightening force honeycomb is repaired screwed assembly, it comprises loss of weight bolt 1 and controlled pretightening force nut 2, wherein, as Fig. 2, loss of weight bolt 1 is made up of the bar 5 that reduces that an end has balancing stand 4, balancing stand 4 arranged outside have wide-angle countersunk head A3, reduce be provided with in the other end inner chamber of bar 5 in mounting hole 7, outer surface is provided with outside thread 6, as Fig. 3, controlled pretightening force nut 2 is made up of the bearing partition 8 of band wide-angle countersunk head B9 and the hexagon head 11 of band cut-off neck slot 10, is provided with endoporus 13 in bearing partition 8 and hexagon head 11 inner chambers, and endoporus 13 is through hole, endoporus 13 is provided with the internal thread 12 that cooperates with outside thread 6 a section of corresponding bearing partition 8, and wide-angle countersunk head B9 links to each other with cut-off neck slot 10.
Mounting hole 7 and endoporus 13 are inner hexagonal hole in described.
The angle of described wide-angle countersunk head A3 and wide-angle countersunk head B9 is 120 °～170 °, and other thin-walled shapes that perhaps satisfy installation requirement get final product;
A kind of controlled pretightening force honeycomb is repaired the using method of screwed assembly, as Fig. 4, earlier loss of weight bolt 1 is passed honeycomb to be repaired 14, the controlled pretightening force nut 2 of packing into then, hexagon head 11 with the controlled pretightening force nut 2 of hexagon wrench twisting, till twisting into two parts hexagon head 11 from cut-off neck slot 10, namely reach predetermined installation pretightening force value.
Wherein, balancing stand 4 major functions are the weight at balance loss of weight bolt 1 two ends and the intensity of strengthening wide-angle countersunk head 3 ends, reduce bar 5 and mainly reduce whole weight, outside thread 6 is mainly used in being threaded with the internal thread 12 of controlled pretightening force nut 2, twisting was used when interior mounting hole 7 mainly was installation and removal, also can get final product for other shapes that satisfy installation requirement, the thickness of cut-off neck slot 10 determines the size of controlled pretightening force, satisfy installation requirement according to pretightening force size requirements control thickness, twisting when hexagon head 11 is mainly used in installing, also can be for other shapes that satisfy installation requirement get final product, endoporus 13 can insert inner hexagon spanner when being used for installing.
