Description
Technical field
The present invention relates to a kind of angle measurement unit technical field, be specifically related to a kind of High-precision pendulum angle measurer.
Background technology
Angle measurement unit is a kind of application sensor widely, when carrying out the observing and controlling of position or speed to the object rotated, just needs to use angle measurement unit.It utilizes angle to change the electronic component coming positioning object position.Be applicable to automobile, engineering machinery, the servo-drive system of universe device, guided missile, rebecca antenna and injection machine, woodworking machinery, printing machine, electronic ruler, robot, engineering monitoring, conputer controlled sports apparatus etc. need the occasion accurately measuring displacement.
Current angle measurement unit is divided into wire wound, condenser type, resistance-type, reluctance type and photo-electric etc., and wherein applying wider is magneto resistive angular sensor, conductive plastic potentiometer and 3-axis acceleration sensor.The shortcoming of magneto resistive angular sensor is that environment for use temperature range is narrow, exigent assembly precision, cannot bear change and load installation requirement that between sensor and magnet, gap is larger, not easily form blast resistance construction.It is ± 0.1% that conductive plastic potentiometer can survey precision, but resistance is subject to ambient humidity impact, and therefore measurement result is not accurate enough.3-axis acceleration sensor can measure the angle of change in 0.25 °, and measuring accuracy is lower.
Summary of the invention
The present invention will provide a kind of measurement result little High-precision pendulum angle measurer affected by environment.
For solving prior art Problems existing, technical scheme provided by the invention is: a kind of High-precision pendulum angle measurer, comprise shell, contiguous block and pendulum, outer shell outer wall is provided with mounting ear, it is characterized in that: described shell is hermetically-sealed construction, its sidewall is fixedly connected with conductive plastic potentiometer, and the rotating shaft end of conductive plastic potentiometer is fixedly connected by the upper end of contiguous block and pendulum, pendulum is provided with obliquity sensor assembly; Described outer casing inner wall is also fixedly connected with summed signal treatment circuit plate, summed signal treatment circuit plate connects with the aviation socket be arranged on shell.
Above-mentioned obliquity sensor assembly is arranged at the surface level center of pendulum.
The material of above-mentioned shell is aluminium or copper.
Upper conductive plastic potentiometer is fixed on shell by installing plate.
Compared with prior art, advantage of the present invention is:
1, environment is very little on measurement result impact, good stability: environment for use temperature range is wide, and under can be applicable to the environment of ﹣ 40 DEG C ~ 85 DEG C, because all measurement mechanisms are seal-installed in housing, so unaffected by ambient humidity, measurement result is accurate.
2, can measure ± 170 ° in change of pitch angle, measuring accuracy is high, and measuring accuracy can reach 0.001 °
3, with low cost, easily manufactured, be applicable to the object measurement of angle under various environment.

Embodiment
Describe the present invention in detail below in conjunction with specific embodiment and accompanying drawing, but the present invention is not limited to specific embodiment.
See Fig. 1 and Fig. 2, a kind of High-precision pendulum angle measurer, comprises shell 1, contiguous block 7 and pendulum 5, and shell 1 outer wall is provided with mounting ear 4.Described shell 1 is hermetically-sealed construction, and its sidewall is fixedly connected with conductive plastic potentiometer, and the rotating shaft end of conductive plastic potentiometer is fixedly connected by the upper end of contiguous block 7 with pendulum 5, pendulum 5 is provided with obliquity sensor assembly 3; Described outer casing inner wall is also fixedly connected with summed signal treatment circuit plate 8, summed signal treatment circuit plate 8 connects with the aviation socket 9 be arranged on shell 1.Described obliquity sensor assembly 3 is arranged at the surface level center of pendulum 5.The material of described shell 1 is aluminium.Described conductive plastic potentiometer 6 is fixed on shell 1 by installing plate 2.
Obliquity sensor assembly 3 in the present invention is known structure, and it comprises obliquity sensor and corresponding treatment circuit plate.
During use, this device is vertically mounted on testee by mounting ear 11.When testee is inclined relative to horizontal certain angle, pendulum 5 drives obliquity sensor assembly 3 still to keep vertical, now conductive plastic potentiometer 6 is according to the change of resistance, can record the inclination angle of pendulum 5 and testee center line, and transfers data to summed signal treatment circuit plate 8.Due to object inertia and friction force effect, pendulum 5 is with a small angle deviating upright position.Because the measuring accuracy of obliquity sensor assembly 3 can reach second, then obliquity sensor assembly 3 detects that the tiny angle measurement value that pendulum 5 departs from is admitted to summed signal treatment circuit plate 8, gather with the detection data of conductive plastic potentiometer 6, obtain the angle value of testee.Finally, data are delivered to outside host computer by aviation socket 9 by high-precision angle value.
