Description
Technical field
The utility model relates to the force moment testing device field, is specially a kind of regulator torsional test instrument.
Background technology
For guaranteeing people's comfort level by bus, the common pitch angle degree of automotive seat is adjustable, to adapt to the requirement by bus of different people.The pitch angle degree of seat is regulated by a rotatable regulator, for guaranteeing the safe and reliable and serviceable life of seat adjustment angle that the torsion that needs test throttle when mounted is to determine whether it meets the requirements.Present method of testing, the rotating shaft of adopting torsionmeter to put regulator is also rotated with test torsion more, judges according to the numerical value that torsionmeter shows whether product is qualified, and this traditional testing process is consuming time long, need take great amount of manpower, inefficiency.
Summary of the invention
In order to overcome the defective of prior art, a kind of convenient test, tester that efficient is high are provided, the utility model discloses a kind of regulator torsional test instrument.
The utility model reaches goal of the invention by following technical solution:
A kind of regulator torsional test instrument, comprise a balance stem and two balanced codes, two balanced codes all are enclosed within on the balance stem, and lay respectively at the both sides of balance stem barycenter, it is characterized in that: also comprise counterweight, displacement transducer, fulcrum and rotation motor, one end of balance stem is fixed a displacement transducer, the adjustment sign indicating number makes that balance stem is that fulcrum is in equilibrium state with the barycenter, the other end of balance stem overlaps a counterweight, rotating shaft center one end of regulator to be tested and the barycenter place of balance stem are connected, the other end connects rotation motor, and counterweight produced is that the moment and the torque direction that regulator produced to be tested of rotating shaft is opposite with the fulcrum.
Described regulator torsional test instrument is characterized in that: an end of balance stem fixed displacement sensor is also fixed a limited block along the outside of a side of rotation motor sense of rotation.
During use, barycenter with balance stem is a fulcrum, end at balance stem is fixed a displacement transducer, the other end is hung a counterweight, the adjustment sign indicating number makes that balance stem is that fulcrum is in equilibrium state with the barycenter, rotating shaft center one end of regulator to be tested and the barycenter place of balance stem are connected, and the other end connects rotation motor.When rotation motor did not drive the regulator rotation, balance stem tilted to counterweight one end.
If the moment of torsion standard of regulator to be tested is M, the distance of counterweight and balance stem fulcrum is L, and the suffered gravity of counterweight is G, if will make the balance stem balance, then between M, L, the G three following relation should be arranged:
M＝G×L
And G=m * g, thereby have: M=m * g * L
Thereby the quality of counterweight then
Now drive the regulator rotation by rotation motor, the rotating speed and the rotating range of rotation motor configure in advance, and the number of turns that rotation motor is rotated is controlled in the maximum number of turns of regulator rotation.Because counterweight produced is that the moment and the torque direction that regulator produced to be tested of rotating shaft is opposite with the fulcrum, therefore, if the moment of torsion of regulator is up to specification, then balance stem is in equilibrium state just, otherwise, balance stem will rotate around fulcrum because of uneven, thus can by displacement transducer detect and send signal and indicated.Drive in the rotary course of regulator at rotation motor, if balance stem is driven rotation, then displacement transducer sends signal, judges that the moment of torsion of this regulator is defective, otherwise if not action of balance stem, then the moment of torsion of this regulator within the limits prescribed.
The utility model is simple in structure, and the testing efficiency height can shorten process cycle and accuracy that the product rotary torsion detects examination entirely, increases work efficiency, and saves human resources.

Fig. 3 is the front view of the present utility model that originally is added with limited block.
Embodiment
Below further specify the utility model by specific embodiment.
A kind of regulator torsional test instrument, comprise a balance stem 1, two balanced codes 2, counterweight 3, displacement transducer 4, fulcrum 6 and rotation motor 7, as depicted in figs. 1 and 2, two balanced codes 2 all are enclosed within on the balance stem 1, and lay respectively at the both sides of balance stem 1 barycenter, one end of balance stem 1 is fixed a displacement transducer 4, adjustment sign indicating number 2 makes that balance stem 1 is that fulcrum 6 is in equilibrium state with the barycenter, the other end of balance stem 1 overlaps a counterweight 3, rotating shaft center one end of regulator 8 to be tested and the barycenter place of balance stem 1 are connected, the other end connects rotation motor 7, and what counterweight 3 was produced is that the moment of rotating shaft and torque direction that regulator 8 to be tested is produced are opposite with fulcrum 6.
Whether the zero load rotation peak torque of existing testing automobile chair regulator meet≤requirement of 0.5Nm, during use, barycenter with balance stem 1 is a fulcrum 6, fix a displacement transducer 4 at an end of balance stem 1, the other end is hung a counterweight 3, adjustment sign indicating number 2 makes that balance stem 1 is that fulcrum 6 is in equilibrium state with the barycenter, and rotating shaft center one end of regulator 8 to be tested and the barycenter place of balance stem 1 are connected, and the other end connects rotation motor 7.When rotation motor 7 did not drive regulator 8 rotations, balance stem 1 tilted to counterweight 3 one ends.
If the moment of torsion standard of regulator to be tested 8 is M, counterweight 3 is L with the distance of balance stem 1 fulcrum, and the suffered gravity of counterweight is G, if will make balance stem 1 balance, then between M, L, the G three following relation should be arranged:
M＝G×L
And G=m * g, thereby have: M=m * g * L
Thereby the quality of counterweight 3 then
Now drive regulator 8 rotations by rotation motor 7, the rotating speed and the rotating range of rotation motor 7 configure in advance, and the number of turns that rotation motor is rotated is controlled in the maximum number of turns of regulator rotation.Because what counterweight 3 was produced is that the moment of rotating shaft and torque direction that regulator 8 to be tested is produced are opposite with fulcrum 6, therefore, if the moment of torsion of regulator 8 is up to specification, then balance stem 1 is in equilibrium state just, otherwise, balance stem will rotate around fulcrum 6 because of uneven, thus can by displacement transducer 4 detect and send signal and indicated.Drive in the rotary course of regulator 8 at rotation motor 7, if balance stem 1 drives rotated, then displacement transducer 4 sends signal, judges that the moment of torsion of this regulator is defective, otherwise if not action of balance stem 1, then the moment of torsion of this regulator within the limits prescribed.
For further improving the security of regulator torsional test instrument when testing, can also be in an end of balance stem 1 fixed displacement sensor 4 the outside along a side of rotation motor 7 sense of rotation, fix a limited block 5, as shown in Figure 3, other structures are all same with embodiment 1.
