Technical field
This utility model relates to the torsion detection technique field of parts, particularly relates to a kind of to automotive seat safety pin
Axle carries out the detection device of high speed twisting property or fatigue test.
Background technology
Constantly come into common people family along with automobile, user vehicle not only power performance and economic performance to automobile proposes
Higher requirement, the most also requires that automobile has reasonable safety.The safety of automobile includes active safety and passive peace
Entirely, and mainly automotive safety bearing pin works in passive security, and in automotive safety bearing pin, some is the torsion by self
Change shape and absorb energy, be the critical component absorbing energy owing to reversing workpiece, therefore typically require and it is reversed
Performance or fatigue behaviour detect, to obtain its performance parameter.
At present, what we were understood is generally divided into two classes for reversing the test method that carries out of workpiece: one is workpiece
Carry out when static, and another to be workpiece carried out under the conditions of low speed reverses.Both test methods all can not
Embodying cannot by actual condition under reversing at a high speed of test piece high speed twisting states under actual condition, i.e. workpiece

Move with stuck test piece on rail two.
High speed torsion detecting device provided by the utility model is loading system operationally to be carried out with rotation system
Separating, when carrying out torsion test, one end of test piece is connected with torque arm fixture, along with driven shaft rotates together,
The other end is connected with fixture spindle and maintains static.And by motor drive drivewheel drive driven pulley do high speed rotating, wait until from
After the rotating speed of driving wheel reaches rotating speed set in advance, controlling drivewheel by pneumatic means and separate with driven pulley, driving shaft drives
Test piece on driven shaft carries out high speed twist motion, makes test piece simulate actual condition at high speeds.Flown by control
The quality of wheel regulates the size of rotary inertia, and when rotary inertia is bigger, test piece will rupture when rotating speed does not also stop,
Used time is shorter；When rotary inertia is less, test piece still will not rupture when rotating speed stops, and the used time is longer.Flown by change
Wheel quality, initial rotational energy can reach 2700J to 14750J when 5000rpm, and meanwhile, the moment of inertia scope is 0.0196kgm2
To 0.1076kgm2；So we just can carry out the high speed torsion test of friction speed to the test specimen of different moments of torsion.Additionally, use
The motor of smaller power just can drive the driven pulley of driving shaft to carry out speed no-load and high rotation, contributes to energy-conservation.

Detailed description of the invention
Core of the present utility model is to provide a kind of high speed that torsion workpiece can carry out high speed torsion test to reverse
Detection device.In order to make those skilled in the art be better understood from this programme, below in conjunction with the accompanying drawings with detailed description of the invention pair
This utility model is described further.
Fig. 1 is the structural representation of the detailed description of the invention of high speed torsion detecting device provided by the utility model, this
" upper and lower, left and right " in literary composition etc. represent that the term in orientation is intended merely to represent the position relationship of subsidiary figure.
In a specific embodiment, high speed torsion detecting device provided by the utility model is mainly by motor 2, driving shaft
6, the composition such as driven shaft 9, torque sensor 12 and high speed angle measuring sensor, it is adaptable to automotive safety bearing pin torque arm
High speed torsion test.
Driving shaft 6 and driven shaft 9 are installed on bearing block by bearing respectively, and driving shaft 6 and driven shaft 9 are coaxial placements
, the right-hand member of driving shaft 6 is relative with the left end of driven shaft 9, have between right-hand member and the torque sensor 12 of driven shaft 9 certain away from
From being to place test piece, torque sensor has for 12 times line slideway two can move back and forth to facilitate the peace of test piece
Dress.
When testing, between test piece torque arm fixture 10 and the fixture spindle 11 that will reverse, and fixture is made to connect
Axle 11 moves clamping test piece to be done to the left along line slideway 2 13.Set at control system guidance panel and want
The rotating speed reached, then controls switch activated.
Now, motor 2 moves downward along line slideway 1 under the effect of pneumatic means, until the drivewheel on motor 2
3 contact with the driven pulley 4 on driving shaft 6 and are adjacent to, and then motor 2 begins to drive drivewheel 3 to rotate, and drivewheel 3 passes through
Frictional force drives the driven pulley 4 one pieces rotation on driving shaft 6, and drivewheel 3 and driving shaft 6 all reach speed set in advance by the time
After, pneumatic means will make motor 2 move upward along line slideway 1 again.Now, driven with on driving shaft 6 of drivewheel 3
Wheel 4 is separated, and pneumatic clutch 7 is started working simultaneously, makes the right-hand member of driving shaft 6 with driven by clutch half a coupler 8
The left end of axle 9 links together, and drives driven shaft to rotate together.
The torque arm fixture 10 that driven shaft right-hand member connects can do high speed twist motion, owing to torque arm is another by motoring ring test workpiece
One end is fixing, fracture, the now high speed angle on driven shaft 9 after therefore torque arm can reverse a few within the shortest time
Degree measures the torque sensor 12 on sensor 18 and torque sensor bearing can write down the size of turn-taked number and moment of torsion respectively.
Thus reach the purpose detecting test data in good time and accurately controlling.
By the combination of the different-thickness to flywheel 5, change the quality of flywheel 5, thus change the rotation of driving shaft 6
Inertia, thus can do the high speed torsion test of different rotating speeds to the test specimen of different moments of torsion.
