Abstract

The invention discloses a honeycomb thread-repairing connecting component with controllable preload and the usage of the connecting component, and the honeycomb thread-repairing connecting component with the controllable preload and the usage of the connecting component include a weight-reducing bolt (1) and a preload-controllable nut (2). The weight-reducing bolt (1) is passed through the honeycomb hole (14) to be repaired, and then put into the preload-controllable nut (2). A hexagonal spanner wrench wrenches a hexagonal head (11) of the preload-controllable nut (2) until breaking down the hexagonal head (11) of the preload-controllable nut (2) at the position of a broken neck groove (10), namely until reaching an expected installation preload value. The honeycomb thread-repairing connecting component with the controllable preload reduces the total quality of the connecting component and satisfies the very beautiful appearance requirements, and has the advantages of high safety and reliability, and convenient to maintain. The honeycomb thread-repairing connecting component with the controllable preload belongs to the best professional thread-repairing connecting component in the honeycomb repairing field.

Description

A kind of controlled pretightening force honeycomb is repaired screwed assembly and using method thereof
Technical field
The present invention relates to a kind of controlled pretightening force honeycomb and repair screwed assembly and using method thereof, belong to the fastening connection piece technical field.
Background technique
In airplane parts design, that high-end fastener technology requires is high, safety reliability good, expensive.Special at some the soft material positions that need to repair, the most frequently used method is exactly that conventional bolt and nut is fastenedly connected, although such link is simple in structure, is not just best for the soft material position of this moment.Outward appearance is not beautiful, and weight is large, and the uncontrollable series of problems that waits of pretightening force embodies a concentrated reflection of.And for example repair the field at honeycomb, the plain bolt nut connects 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.
Summary of the invention
The object of the present invention is to provide a kind of controlled pretightening force honeycomb to repair screwed assembly and using method thereof, can solve honeycomb and repair the positive mechanical connectivity problem in field, can reduce gross mass, can obtain again strict beautiful appearance requirement, realize that pretightening force is controlled.
the objective of the invention is to be 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 comprised of the bar that reduces of an end with 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 by forming with the bearing partition of wide-angle countersunk head B with the hexagon head of cut-off neck slot, be provided with endoporus in bearing partition and hexagon head inner chamber, endoporus is through hole, endoporus is provided with a section of corresponding bearing partition the internal thread that coordinates with outside thread, wide-angle countersunk head B is connected with cut-off neck slot.
Described interior mounting hole and endoporus are inner hexagonal hole.
The angle of described wide-angle countersunk head A and wide-angle countersunk head B is 120 °~170 °.
A kind of controlled pretightening force honeycomb is repaired the using method of screwed assembly, first the loss of weight bolt is passed honeycomb to be repaired, then the controlled pretightening force nut of packing into, hexagon head with the controlled pretightening force nut of hexagon wrench twisting, until till twisting into two parts hexagon head from cut-off neck slot, namely reach predetermined installation pretightening force value.
Beneficial effect of the present invention is: the gross mass that has both reduced link, satisfied again strict beautiful appearance requirement, and pretightening force is controlled, and has safety reliability characteristics high, easy to maintenance, repairs the best specialty in field for honeycomb and repairs screwed assembly.
Description of drawings
Fig. 1 is structural representation of the present invention;
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 diagram of the present invention.
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 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 technological scheme of the present invention 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 comprised of the bar 5 that reduces of an end with balancing stand 4, balancing stand 4 arranged outside have wide-angle countersunk head A3, reduce in the other end inner chamber of bar 5 and be provided with interior mounting hole 7, outer surface is provided with outside thread 6, as Fig. 3, controlled pretightening force nut 2 is by forming with the bearing partition 8 of wide-angle countersunk head B9 with the hexagon head 11 of cut-off neck slot 10, be provided with endoporus 13 in bearing partition 8 and hexagon head 11 inner chambers, endoporus 13 is through hole, endoporus 13 is provided with a section of corresponding bearing partition 8 internal thread 12 that coordinates with outside thread 6, wide-angle countersunk head B9 is connected with cut-off neck slot 10.
Described interior mounting hole 7 and endoporus 13 are inner hexagonal hole.
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, first loss of weight bolt 1 is passed honeycomb to be repaired 14, then the controlled pretightening force nut 2 of packing into, hexagon head 11 with the controlled pretightening force nut 2 of hexagon wrench twisting, until 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 and the intensity of strengthening wide-angle countersunk head 3 ends at balancing weight-reduction bolt 1 two 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, when interior mounting hole 7 is mainly installation and removal, twisting is used, 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, control thickness according to the pretightening force size requirements and satisfy installation requirement, twisting when hexagon head 11 is mainly used in installing, also can get final product for other shapes that satisfy installation requirement, endoporus 13 can insert inner hexagon spanner when being used for installing.
