Put.
Background technology
For screw thread specification less than M3, bolt and the spiral shell not specifying lowest pull load in GB3098.1 with ensureing load
Nail；And nominal diameter 3-10mm, but length is the shortest and can not implement bolt and the screw of pull test, and we need to be according to test
Standard GB/T3098.13-1996 carries out failure test, tests its mechanical performance.
Device shown in standard GB/T3098.13-1996, between rotating tool head and securing member sample can not automatic centering, need
Centering manually, it is impossible to realize automatization, increases difficulty and the human cost of test.Simultaneously in process of the test, need
The artificial pressure applied between rotating tool head and securing member, thus produce unnecessary error, affect test result.
Testing machine in document " CN03229751-microcomputer controlled torque tester " has torque value, torsion angle, rotating speed
Function is arbitrarily set etc. index, is suitable for different test request；On the basis of this torsion testing machine, for screw thread specification less than M3
And nominal diameter 3-10mm, but length is the shortest and can not implement bolt and the screw of pull test, according to test standard GB/
T3098.13-1996 requirement, removes the electric control system in microcomputer controlled torque tester, improves microcomputer and controls to reverse examination
Test the host machine part in machine, it is achieved the destructive testing of threaded fastener sample, reach to test the purpose of its mechanical performance.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of torsion testing machine threaded fastener clamping device, energy
Enough realize screw thread specification less than M3 and nominal diameter 3-10mm, but length is the shortest and can not implement bolt and the spiral shell of pull test
The destructive testing of nail.
A kind of torsion testing machine threaded fastener clamping device, including threaded fastener clamping device and torsion testing machine,
Threaded fastener clamping device includes threaded fastener sample, split thread bush and spring chuck, and threaded fastener sample is installed
In the split thread bush of threaded fastener clamping device, split thread bush is inserted in spring chuck, and spring chuck is respectively arranged with up and down
One draw-in groove, has two dog chucks on torsion testing machine, and in two dog chucks, two pawl positions are corresponding with the position of draw-in groove, make
In spring chuck and two dog chucks, chuck is effectively combined, and threaded fastener clamping device is arranged on torsion testing machine
On.
Described spring chuck uses elastic opening formula, and described split thread bush is the split forms of two halves, and split thread bush is opened
Mouth needs consistent with spring chuck opening direction.
Described torsion testing machine is arranged on scooter, fixes a pneumatic spring, pneumatic spring and torsion on scooter
The bottom turning testing machine is connected, when, after split thread bush with threaded fastener sample contacts, pneumatic spring loads split spiral shell automatically
Axial compressive force required between stricture of vagina set and threaded fastener sample.
Beneficial effect
Torsion testing machine threaded fastener clamping device of the present utility model, by two dog chucks by two pawls and screw threads for fastening
Part clamping device is effectively combined, and replaces Manual alignment threaded fastener sample center, and the centering meeting securing member is fixed
Position requirement, it is achieved centering location automatization, greatly reduces the difficulty of test and saves human cost；Split thread bush is two
Half split form, can in process of the test fast assembling-disassembling sample, particularly after off-test, it is possible to rapidly take out suffer
The threaded fastener sample destroyed, improves test efficiency；Use pneumatic spring to replace manually and apply split thread bush and screw thread
Axial compressive force required between securing member sample, it is to avoid produce unnecessary error, affect test result.
Accompanying drawing explanation
