Abstract

A kind of carrying hanger bolt tension measurement structure, including bolt (1), foil gauge (2) and measurement line delivery outlet (3), it slots at bolt (1) polished rod position, foil gauge (2) is attached in slot, measurement line delivery outlet (3) is provided with position corresponding with polished rod position slotting position on the bolt head of bolt (1), line connection foil gauge (2) is measured, and is pierced by from measurement line delivery outlet (3).The utility model is easy to operate, can bolt strained state in rapid survey use process, various sizes of bolt can be applied according to the size of foil gauge.

Description

A kind of carrying hanger bolt tension measurement structure
Technical field
The utility model belongs to strength test field, is related to a kind of bolt tension force measurement structure, holds more particularly to one kind Carry hanger bolt tension measurement structure.
Background technique
Guided missile hanging connects major mechanical interface as firing mount, hangs during flying, and various alternating loads are born in hanging, generates Fatigue cumulative damage.Guided missile hanging is mostly used with bomb body to be bolted,
Bolt bears pretightning force load and on-hook load.What the stress of connection bolt directly influenced total can By property and safety.Connection bolt is mounted in hanging and bomb body bolt hole, and extension flies over Cheng Wufa and directly monitors vibratory impulse Load;Because most of forced position does not have space patch foil gauge can not directly measure bolt strained state yet when slow test.
Pulling force is born to bolt in industry and is mainly the following measurement method: resistance strain gage electrical measuring method, photorefraetive crystal, Mistor sensor measurement method and supercritical ultrasonics technology etc..Except photorefraetive crystal, remaining is used equally under load condition above-mentioned measurement method The measurement of hanger bolt pulling force.But it needs to purchase special equipment and builds measurement acquisition system, and is complicated for operation cumbersome, it is different Surely ideal measurement result, waste of manpower, financial resources are obtained.
Summary of the invention
The purpose of the present invention: a kind of carrying hanger bolt tension measurement structure is proposed, in order to without using special In the case where door equipment, it is quickly obtained stress when guided missile hanging connect bolt carrying with bomb body.
Technical solution of the present invention:
A kind of carrying hanger bolt tension measurement structure, including bolt 1, foil gauge 2 and measurement line delivery outlet 3, in bolt 1 Polished rod position fluting, foil gauge 2 are attached in slot, and measurement line delivery outlet 3 is provided on the bolt head of bolt 1 slots with polished rod position Position corresponding, measurement line connects foil gauge 2, and is pierced by from measurement line delivery outlet 3.
A kind of carrying hanger bolt tension measurement structure, the slot that 1 polished rod position of bolt opens up are four, four slots Between along the circumferential 90 ° of symmetric configurations two-by-two each other of shank of bolt.
A kind of carrying hanger bolt tension measurement structure, in 1 polished rod position slotting position of bolt except patch foil gauge 2 Other positions outside position apply insulating materials, and measurement line is isolated with other metal structures in addition to foil gauge 2.
A kind of carrying hanger bolt tension measurement structure, foil gauge 2 is unidirectional foil gauge, along perpendicular to bolt end Face direction is posted in slot.
Advantages of the present invention: the measurement structure is simple and reliable, easy to operate, be able to achieve bolt with hanging assembly it is narrow In space, the complicated applied force state of bolt is obtained.Buying special equipment is not needed, manpower, financial resources are saved.
Detailed description of the invention:
Fig. 1 is bolt patch location schematic diagram;
Fig. 2 is bolt schematic diagram;
Fig. 3 is bolt head opening schematic diagram;
1, bolt, 2, foil gauge, 3, measurement line delivery outlet.
Specific embodiment:
The invention will be described in further detail with reference to the accompanying drawing.
Referring to figures 1-3, which uses the bolt 1 of secondary operation, foil gauge 2 and measurement line delivery outlet 3.Bolt 1 in polished rod position symmetrical grooving two-by-two, and totally four slots, symmetrical channels need high light cleanliness, guarantee that the depth of slot is big in bolt Within diameter and path dimension difference range, fluting will not influence bolt actual loading situation.Four foil gauges 2 are attached to symmetrical two-by-two In slot, foil gauge should have with end face is bolted compared with high verticality.Bolt 1 corresponds to slotting position on bolt head and opens four circles Hole, the hole measure line delivery outlet 3 as foil gauge.Do not include simultaneously bolt, hanging short circuit with testpieces to measure line, influences DATA REASONING precision applies insulating cement or resin glue except patch foil gauge position in 1 slotting position of bolt, and will answer with the glue Become piece two and exports filament isolation.
The utility model is easy to operate, can bolt strained state in rapid survey use process, can be according to the ruler of foil gauge The very little various sizes of bolt of application.
