Existing angular transducer need detect its precision before using, and reduced the error that is caused when measuring using.Especially used the angular transducer of a period of time for some, it is particularly important that accuracy detection seems.But the angle sensor carries out accuracy detection and need use a cover detection system in the prior art, though the precision of demarcating is higher, system is comparatively complicated, cost is also higher.
Like the Chinese patent publication number be: CN101135579A; In on March 5th, 2008 disclosed a kind of high-precision angle sensor detector methods and device; Comprise physical construction part, motor and control section, data acquisition, transmission and processing section, multiple power supplies management four most of compositions; Adopt certain reduction gear ratio worm and gear that the tested angle sensor is slowed down; Adopt the shaft coupling of multiple different-diameter, adopt the multifunctional angular sensor installing plate that adapts to different size, the base of adjustable installation site to adapt to the angular transducer of different size, adopt singlechip technology control step motor; Make tested angle sensor output specified angle through worm and gear speed-reduction apparatus, adopt the common increment counterweight that the motor rotational angle is monitored.Though this patent measuring accuracy is high, more numerous and diverse being not easy to of assembling of the various cost height of member, mechanical part and control section produced.
Summary of the invention
The utility model mainly be various to existing angle sensor calibration system architecture complex component, cost is higher, be not easy to the problem of assembling and producing, and a kind of plain type angle sensor calibration apparatus that demarcation, cost are lower, be convenient to produce that can the angle sensor detects is provided.
The purpose of the utility model mainly is achieved through following proposal: a kind of plain type angle sensor calibration apparatus; Comprise pedestal, locating piece and hold-down bars; Described pedestal is provided with the cavity that is used for fixing angular transducer; Described cavity center is provided with the centre of location hole that is used for angle sensor rotation axis location, and described locating piece one end is provided with the fixed orifice that is used for fixing the angular transducer rotation axis, the axis in described centre of location hole and the dead in line of fixed orifice; Evenly be provided with several angle holes around centre of location hole on the described pedestal, described locating piece is provided with the hold-down bars pilot hole away from an end of fixed orifice, the dead in line in the axis of described hold-down bars pilot hole and any angle hole.Cavity on the pedestal is used for fixing angular transducer; The rotation axis of angular transducer is passed centre of location hole and the fixed orifice on the locating piece in the cavity successively; Be fixedly connected with locating piece through the rotation axis of the fixed orifice on the locating piece, locating piece can be rotated around centre of location hole angular transducer.In the angle hole that is provided with around centre of location hole on the pedestal any one can both with the hold-down bars pilot hole dead in line on the locating piece, promptly the centre distance of the centre distance in centre of location hole and angle hole and centre of location hole and hold-down bars pilot hole is identical.Because the angle hole is evenly to be provided with, so the angle between adjacent two angle holes is a definite value, adopt hold-down bars to pass after the hold-down bars pilot hole on one of them angle hole and the locating piece, measure data; Again hold-down bars is passed on another adjacent angle hole and the locating piece after the hold-down bars pilot hole, measure another data.Angle definite value through between two data detecting and two the angle holes is compared.And the like, several angle holes are detected successively and compared, the angle sensor detects and demarcates.
As preferably, the both sides that are positioned at fixed orifice on the described locating piece are provided with first fastening bolt that is used for fixing the angular transducer rotation axis.In the fixed orifice both sides first fastening bolt is set, the rotation axis of angular transducer is passed fixed orifice after, adopt the rotation axis of the first fastening bolt angle sensor of both sides to be fixedly clamped.
As preferably, described angle hole is a through hole, and described hold-down bars runs through angle hole and hold-down bars pilot hole.When the angle hole was through hole, the hold-down bars pilot hole on the locating piece was passed in the angle hole that hold-down bars can pass earlier on the pedestal again; The hold-down bars pilot hole that also can pass earlier on the locating piece passes the angle hole on the pedestal again.
As preferably, be positioned at hold-down bars pilot hole both sides on the described locating piece and be provided with second fastening bolt that is used for fixing hold-down bars.When the angle hole is through hole, in the both sides of hold-down bars pilot hole second fastening bolt is set the hold-down bars that passes the hold-down bars pilot hole is fixedly clamped, reduce because the calibrated error that the hold-down bars swing causes.
Described angle hole also can be the blind hole that is positioned on the side opposite with cavity, and described hold-down bars runs through the hold-down bars pilot hole and is threaded with the angle hole.When the angle hole was blind hole, blind hole was the threaded hole that is positioned on the opposite side of cavity, and hold-down bars is threaded with the angle hole after passing the hold-down bars pilot hole on the locating piece again, reduced because the calibrated error that the hold-down bars swing causes.
As preferably, be embedded with the adjustment disk, described adjustment disk and the cavity interference fit that are used to regulate the cavity size in the described cavity.For the angular transducer of different model, size is had nothing in common with each other, and in order to satisfy the fixing of the big or small angular transducer of difference, is embedded an adjustment disk in the cavity inside of pedestal, and adjustment disk inside has the cavity identical with cavity shapes.When being embedded adjustment disk in cavity,, be fit to small-sized angular transducer because the wall thickness of adjustment disk itself can reduce the original spatial accommodation of cavity.If desired more large-scale angular transducer is carried out timing signal, can adjustment disk be taken out, adopt the cavity of original size to fix.
Therefore; The plain type angle sensor calibration apparatus of the utility model possesses following advantage: the angle hole that 1, a plurality of definite values are set on pedestal; Adopt fixing according to the angle hole successively data of rotating of locating piece and hold-down bars with the angle of detection angles sensor; The definite value that detects data and angle hole is compared the precision of demarcating angular transducer, and the simple cost of member is low; 2, the rotation axis of angular transducer passes fixed orifice on the locating piece after passing the centre of location hole on the pedestal again, and is through first fastening bolt that rotation axis is fastening, avoids the rotation axis swing to cause calibrated error, improved the precision of demarcating; 3, an adjustment disk is set in cavity, adjustment disk can dwindle the original size of cavity, is fit to small-sized angular transducer and uses.
