The utility model provides an it has economic, swift practicality again to improve tentation data precision method. Particularly obvious to in batches experimental effect, the commonality of anchor clamps makes it should tackle the experiment of zero hour nature and becomes unusual swift, and this set anchor clamps can supply mechanics material test room as its basic configuration anchor clamps.
Description
Technical field
This utility model belongs to aeronautical and space technology mechanics testing of materials field, relates to a kind of Novel bolt stretching experiment universal fixture.
Background technology
In order to investigate the mechanics of bolt, mechanical performance, it is necessary to bolt is tested.In bolt is tested, usually meeting and to do plurality of specifications and batches of test situation simultaneously, the fixture conventionally designed carries out testing, and only fixture will overlap more, and installs the sleeve barrel tool of test specimen generally also too busy to get away corresponding specification, requires great effort time-consuming.It addition, what measure that bolt deflection generally adopts is measure machine crosshead travel amount substitution method, thus there is bigger measurement error.
Utility model content
For the installation difficulty of current bolt test fixture existence, measurement test specimen displacement parameter error is big, lack the problems such as versatility, its traditional design scheme has been carried out many-sided improvement by this utility model fixture, making its work efficiency be improved significantly, the measured value of bolt deformation is more accurate.Bolt tension test fixture is no longer be only applicable to the bolt test of single specification and a certain type cartridge form.
This utility model adopts the technical scheme that: a kind of bolt tension experiment universal fixture includes connecting rod 1, sleeve；Sleeve has two pieces, respectively the first sleeve 2 and the second sleeve 8, is vertically connected with each one of bar；Sleeve is axially provided with square through hole, and the first sleeve 2 and the second sleeve 8 are respectively provided with a through hole for measuring UUT, and it is arranged on one end of the first sleeve 2 and the second sleeve 8, and the other end at the first sleeve 2 and the second sleeve 8 is provided with connecting rod 1.
Further, the sidewall of above-mentioned first sleeve 2 has hole, the sensor 3 directly measuring displacement screw amount is installed.
The beneficial effects of the utility model are: not only provide raising test data precision methods but also have economy, efficiently practicality.Particularly evident for bulge test effect, the versatility of fixture makes it should tackle zero time property test to become abnormal quick, and this sleeve clamp is available for mechanics material testing laboratory as its basic configuration fixture.

Detailed description of the invention
Below in conjunction with Figure of description, this utility model is described in further detail.
A kind of bolt tension experiment universal fixture includes connecting rod 1, sleeve and packing ring；Sleeve has two pieces, respectively the first sleeve 2 and the second sleeve 8, is vertically connected with each one of bar；Sleeve is axially provided with square through hole, and the first sleeve 2 and the second sleeve 8 are respectively provided with a through hole for measuring UUT, and it is arranged on one end of the first sleeve 2 and the second sleeve 8, and the other end at the first sleeve 2 and the second sleeve 8 is provided with connecting rod 1；For ease of installing and observation test specimen deformation particular procedures in test, by having opened a large square through hole in cartridges sides, traditional fixture bolt is put into mouth and has been changed into open installation by enclosed；One end with the connecting rod 1 of sleeve connection is designed to the external thread rod of fixed dimension, at the other end being held on testing machine fixture block, then according to carrying out designed size needed for chuck or form is determined, thus for the particular/special requirement of different tests machine fixture block, as long as changing corresponding connecting rod.
Further, the sidewall of above-mentioned first sleeve 2 has hole, the sensor 3 directly measuring displacement screw amount is installed.By arrange sensor 3 completely eliminate by measure crosshead travel replace bolt deflection time, the gap error that fixture block and connecting rod 1 part are brought.
The using method of this sleeve clamp is:
1) first the external thread rod part of connecting rod 1 is rotated into the first sleeve 2 and the second sleeve 8；
2) sensor 3 is inserted in the autocratic installing hole on sleeve A, locked with its shop bolt 4 after adjusting position；
3) the non-external screw thread rod end of connecting rod 1 is accommodated on the fixture block of testing machine；
4) clip position of testing machine is adjusted with displacement-control mode so that it is be rotated into the both ends of the surface connecting test specimen of the first sleeve 2 and the second sleeve 8 close to fitting；
5) bolt test specimen is penetrated two holes connecting test specimen end face of circular arc packing ring the 6, first sleeve 2 and the second sleeve 8, then is inserted in faced washer 7, nut of finally screwing at bolt screw rod position；
6) test specimen complete test after unload destruction test specimen, re-execute 4), 5) step, until completing the test of all test specimens.Adopt set packing ring in bolt, when purpose is to meet the test of different specification size bolt, adapt to by changing the packing ring of corresponding bolt specification, the end face of one of another packing ring, the cambered surface form being designed to coordinate with the first sleeve 2 can make test specimen automatic centering when stretching, and is conducive to test to improve precision.The sidewall of the first sleeve 2 has hole, the sensor directly measuring displacement screw amount is installed.
