Description
Technical field
The utility model relates to the loosening test device that bolt group connects under a kind of lateral load.
Background technology
Bolt connection is widely used in physical construction, the advantages such as structure is simple, connection is reliable, convenient disassembly that it has, and as important link, the safety and reliability of its performance on structure has larger impact.These structures in use, are subject to the effect of alternation external force for a long time, and this just inevitably makes bolt fastening structure occur to loosen, and the loosening machinery and equipment that causes of securing member breaks down, and reduces the reliability of machinery and equipment; Even security incident can be there is, the serious threat person and property safety.Therefore, need to find out bolt fastening structure loosen the relation with load, material by test, for the design of bolt fastening structure, manufacture, use provide reliable test basis.
The loosening test device of the bolt fastening structure at present under axial alternate load (axis being parallel of loading direction and bolt arrangement) is more, better can carry out loosening test.But under lateral load (axes normal of loading direction and bolt arrangement), the loosening test device of bolt fastening structure is then little.The custom-designed transverse vibration platform of usual needs, kinematic train, chucking appliance system, mounting base and measurement mechanism, it forms complexity, expensive; And loosening test can only be carried out to single bolt.And in actual applications, the thread connection of most of machine uses all in groups, little used aloned, such as, pipe arrangement seat is connected by 4 bolt groups with between gas path plate.
Utility model content
The purpose of this utility model is to provide the loosening test device that bolt group connects under a kind of lateral load.The bolt group that this kind of device can be formed two bolts carries out loosening test under lateral load, and its structure is simple, cheap.
The technical scheme that the utility model realizes the employing of its goal of the invention is: the loosening test device that under a kind of lateral load, bolt group connects, and comprise grip block, lower grip block, its design feature is:
The upper and lower of described upper grip block is staggered in N font; Upper grip block top is the upper bare terminal end that can coordinate with fatigue tester upper grip, the side of upper grip block bottom is processed with the upper plate groove of two placement force cells, have the upper plate side channel of the data line for deriving force cell between the edge of upper plate recess edge and upper grip block, the centre position of upper plate groove has for the upper plate through hole through test bolt;
Described lower grip block bottom is the lower bare terminal end that can coordinate with fatigue tester lower chuck, the upper plate groove relative position of lower grip block top and upper grip block is provided with lower plate groove, described lower plate groove is for placing force cell, have the lower plate side channel of the data line for deriving force cell between the edge of lower plate recess edge and lower grip block, the centre position of lower plate groove has for the lower plate through hole through test bolt.
Using method of the present utility model is:
Insert in upper plate groove and lower plate groove by packing ring, force cell, the data line of force cell is drawn from upper plate side channel and lower plate side channel.2 test bolts put on successively plate through hole, packing ring, force cell, packing ring, pass lower plate through hole again, nut of screwing on subsequently.Lower bare terminal end is fixed on the testing table of fatigue tester, the upper bare terminal end of torture test machine grip holder clamping, and lateral load is applied to it, thus the loosening test of bolt group under carrying out lateral load.
Compared with prior art, the beneficial effects of the utility model are:
The arrangement achieves the loosening test of bolt group, loosening test process only needs two grip blocks, and structure is simple, saves experimentation cost.The High Precision Strength Measurement Sensor that transverse load is carried by fatigue tester is measured and is monitored, transverse force precise control.Be placed in by force cell between two grip blocks, be convenient to protect force cell, meanwhile, force cell is on the horizontal line of test bolt, not by the impact of transverse load, and the accuracy of warranty test result and reliability.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
