Embodiment
See also Fig. 1, it is the structural representation of obliquity sensor static calibration device one better embodiment of the present invention.In the present embodiment, described calibrating device for tilt angle sensor comprises mounting base 1, optical dividing head 2, installation shaft 3, installing plate 4, top 5, top pedestal 6, top handle 7.Wherein, described mounting base 1 comprises a horizontal base plate 8 and perpendicular to the base station 9 and the top pedestal 6 of horizontal base plate 8.Described optical dividing head 2 is arranged on the base station 9, is carved with angle index on it, and its axle center is parallel with horizontal base plate 8.Described top pedestal 6 is arranged on the horizontal base plate 8, and the tail spindle line parallel is in horizontal base plate 8.Described top 5 are arranged on the side that top pedestal 6 closes on base station 9, and described top handle 7 is arranged on the opposite side that top pedestal 6 deviates from optical dividing head 2.Wherein, described optical dividing head 2 successively by installation shaft 3 be arranged on top pedestal 6 on top 5 link to each other.And described optical dividing head 2 and installation shaft 3, top 5 the centre of gyration are coaxial, and the axle core is perpendicular to base station 9.
In addition, because the mandrel of optical dividing head 2 is a tail spindle 10, inconvenience directly connects.Therefore in the present embodiment, described installation shaft 3 and optical dividing head 2 end that joins is one can accommodate the installing and locating hole 17 of optical dividing head tail spindle 10, and has threaded hole 11 on this installing and locating hole 17.Simultaneously, described installation shaft 3 other ends have one and can accommodate top 5 center hole 14.When top pedestal 6 moves to the appropriate location, top 5 are positioned in the center hole 14 of installation shaft 3, make top termination unsettled, thereby avoid the infringement to top termination., optical dividing head tail spindle 10 and installing and locating hole 17 can be locked with top 5 with after tail spindle 10 adjusts to the exact position by top handle 7, thereby guarantee installation shaft 3 and optical dividing head 2 centre of gyration coaxial separately by jackscrew.And described installation shaft 3 has a transverse concave groove that is used to prevent installing plate 4.
Please consult Fig. 2 and Fig. 3 simultaneously, wherein, Fig. 2 is the vertical view of described installation shaft, and Fig. 3 is that the A of Fig. 2 is to cut-open view.In the transverse concave groove of installation shaft 3, and after installing plate 4 was installed in the groove, its upper surface was the plane at axial line place to described installing plate 4 by the screw retention on the mounting hole 12.Described installing plate 4 also has two sensor mounting holes 13 that are used to lock obliquity sensor, and by screw fixedly locked obliquity sensor on sensor mounting hole 13.
When obliquity sensor of the present invention connects, at first will; Installation shaft 3 has an end in installing and locating hole to be installed in locking on the tail spindle 10 of optical dividing head 2; Then top pedestal is transferred to correct position, makes top 5 to be positioned in the center hole 14, by lock screw 15 lockings; Again by top handle 7 make top 5 and installation shaft 3 be in the tram, make that the centre of gyration of installation shaft 3 is coaxial with the centre of gyration of optical dividing head 2, will fixedly mount threaded hole 11 locking on the pilot hole 17 then.Secondly installing plate 4 is installed on two pilot holes of installation shaft 3 grooves by sunk screw, and assurance is vertical with the axis of rotation of installation shaft.To treat the obliquity sensor 16 in school, the mounting hole by two mounting holes on the installing plate 4 and obliquity sensor 16 self is installed on the installing plate 4, and the rotation direction that guarantees obliquity sensor with the axle axis normal is installed.Thereby can calibrate by optical dividing head obliquity sensor 16.
During actual alignment, because by adjusting, the installation shaft center positioning hole is coaxial with the optical dividing head centre of gyration, and being locked by screw 15 and screw hole 11.Therefore, if the obliquity sensor of different physical dimension, specification, model is calibrated, the installing plate that only needs to change the established angle displacement transducer gets final product, and need not to carry out again same axial adjustment.
So simple to operate, easy accessibility of calibrating device for tilt angle sensor of the present invention, work efficiency is higher, and because the centre of gyration of installation shaft is coaxial with the centre of gyration of optical dividing head, the rotation direction of obliquity sensor and installation axle axis normal, therefore the data that collect have bigger actual application value accurately and reliably.
