Abstract
The utility model discloses a kind of automobile combined switch to stir action force test device, including torque sensor（1）, torque sensor（1）It is mounted on crossbeam by transition head（2）Middle part, crossbeam（2）On pass through bolt（3）Two symmetrical rotating parts are installed（4）, rotating part（4）Upper installs fixture（6）, fixture（6）Side installation locking nut（5）.The utility model rotation center of handle and rotation center of motor when measuring are maintained in an axial direction, it is ensured that torque direction is in vertical with the handle moment.
Description
Technical field
The utility model is related to a kind of closing detecting apparatus.
Background technology
The measurement that automobile combined switch stirs operation force is in the past detected it using hand-held dynamometer, measures
Position is generally at the 10mm of handle end.In measurement process, handle is rotating, it is ensured that the essence of measurement
Degree, it is necessary to which the moment keeps being in for the handle moment of dynamometer and stacked switch to be mutually perpendicular to, the rotation of the handle of stacked switch
The angle moment is changing in the process, and this requires the angles of dynamometer also to change at any time.And the people of its variation is uncontrollable,
Therefore cause measure there are corresponding errors.
Due to being required to measuring position（At 10mm away from handle end）, change in location can cause the change of test result
Change, if distance is less than 10mm, is equivalent to arm of force lengthening, measured power will be smaller than actual forces；If distance is more than 10mm, quite
Shorten in the arm of force, measured power will be bigger than actual forces.Therefore 10mm is a position that must be kept always.
The direction of power is required to remain vertical with the axial direction of handle always when in addition measuring, handle is stirring rotation
Be that the angle moment is becoming, and process of this variation be in measurement process it is difficult to predict, therefore the direction of moment retentivity
Always remaining vertical with the axial direction of handle can not accomplish.
Based on above two reason, deposited with hand-held dynamometer to measure the operation force of automobile combined switch tumbler switch
In larger error, for current requirements more and more accurately in the case of, how to eliminate this kind of measurement error and compeled in eyebrow
Eyelash.
Invention content
The technical problems to be solved in the utility model：For measurement error problem existing for hand-held dynamometer, provide
A kind of automatic detection device.
Technical solution of the present invention：
A kind of automobile combined switch stirs action force test device, including torque sensor, and torque sensor passes through transition
Head is mounted in the middle part of crossbeam, installs two symmetrical rotating parts by bolt on crossbeam, installs fixture on rotating part, fixture side
Installation locking nut.
Crossbeam center opens up a hole, and rotating part can adjust its installation site on crossbeam by bolt.
There is size scale on crossbeam.
Fixture is made of two clamping plates, and the clamping part of triangle is opened up on the fit inside face of two clamping plates.
The beneficial effects of the utility model：
Being rotated using motor when torque measurement drives stacked switch handle to circle.Clamping is tested in the process
Position changes will not have error generation to measurement result, because the torque at each moment is not in entire measurement process
Become, the rotation center of handle and the rotation center of motor are maintained in an axial direction, it is ensured that when torque direction is with handle
It carves in the problem of vertical, also avoiding mentioned in background technology two influences measurement accuracy.
Figure of description：
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is the side view of Fig. 1.
Specific implementation mode：
Embodiment：Such as figure, crossbeam 2 opens up hole along its axis, and torque sensing is installed in 2 center of crossbeam by transition head
Device 1, the fit clearance between transition head and torque sensor：When the opening groove width of torque sensor is 10mm.When groove depth 15mm,
Difference 0.1mm can generate 0.5 ° of error, therefore it is required that the fit clearance between it is not greater than 0.03mm.The item of crossbeam 2
Two symmetrical rotating parts 4 are installed by bolt 3 in hole, have size scale on crossbeam 2, the installation site of rotating part 4 can
To adjust after unclamping bolt 3, ensure that two rotating parts 5 are symmetrically installed by scale.Installs fixture 6 on rotating part 4,6 side of fixture
Face installation locking nut 5.Fixture 6 is made of two clamping plates, and the clamping part of triangle is opened up on the fit inside face of two clamping plates,
Stacked switch handle is placed in the clamping part between two clamping plates, locking nut 5 is tightened.
In order to ensure rectify and improve the device influence of inertia to measurement result in rotary course, used in material should have one
Fixed hardness, and light feature, therefore aluminium is used in the present embodiment.
