Description
Technical field
The utility model relates to a kind of angle measurement unit technical field, is specifically related to a kind of high precision pendulum angle measurement unit.
Background technology
Angle measurement unit is a kind of application sensor very widely, when the object that rotates is carried out the observing and controlling of position or speed, just need use angle measurement unit.It is the electronic component that utilizes angle to change to come the positioning object position.Be applicable to automobile, engineering machinery, the servo-drive system and the injection machine of universe device, guided missile, rebecca antenna, woodworking machinery, printing machine, electronic ruler, robot, engineering monitoring, computer controlled motion apparatuses etc. need the occasion of accurate Displacement Measurement.
Angle measurement unit is divided into wire wound at present, condenser type, and resistance-type, reluctance type and photo-electric etc., what wherein application was wider is reluctance type angular transducer, conductive plastic potentiometer and 3-axis acceleration sensor.The shortcoming of reluctance type angular transducer is to use ambient temperature range narrow, and exigent assembly precision cannot bear bigger variation and the load installation requirement in gap between sensor and the magnet, is difficult for forming blast resistance construction.It is ± 0.1% that conductive plastic potentiometer can be surveyed precision, but resistance is subject to the ambient humidity influence, so measurement result is not accurate enough.3-axis acceleration sensor can be measured the angle that changes in 0.25 °, and measuring accuracy is lower.
The utility model content
The utility model will provide a kind of measurement result little high precision pendulum angle measurement unit affected by environment.
For solving the problem that prior art exists, the technical scheme that the utility model provides is: a kind of high precision pendulum angle measurement unit, comprise shell, contiguous block and pendulum, outer shell outer wall is provided with mounting ear, it is characterized in that: described shell is a hermetically-sealed construction, be fixedly connected with conductive plastic potentiometer on its sidewall, the rotating shaft end of conductive plastic potentiometer is fixedly connected by the upper end of contiguous block and pendulum, and pendulum is provided with the obliquity sensor assembly; Also be fixedly connected with on the described outer casing inner wall and gather signal processing circuit board, gather signal processing circuit board and join with the aviation socket that is arranged on the 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.
Last conductive plastic potentiometer is fixed on the shell by installing plate.
Compared with prior art, the utility model has the advantages that:
1, environment is very little to the measurement result influence, and good stability: the environment for use temperature range is wide, can be applicable under the environment of 40 ℃ ~ 85 ℃ of ﹣, because all measurement mechanisms are seal-installed in the housing, so be subjected to ambient humidity unaffected, measurement result is accurate.
2, can measure ± inclination angle in 170 ° changes, the measuring accuracy height, and measuring accuracy can reach 0.001 °
3, with low cost, easily manufactured, be applicable to the object measurement of angle under the various environment.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cut-open view of Fig. 1.
Wherein, 1. shell; 2. installing plate; 3. obliquity sensor assembly; 4. mounting ear; 5. pendulum; 6. conductive plastic potentiometer; 7. connecting link; 8. gather signal processing circuit board; 9. aviation socket.
Embodiment
Describe the utility model in detail below in conjunction with specific embodiment and accompanying drawing, but the utility model is not limited to specific embodiment.
Referring to Fig. 1 and Fig. 2, a kind of high precision pendulum angle measurement unit comprises shell 1, contiguous block 7 and pendulum 5, and shell 1 outer wall is provided with mounting ear 4.Described shell 1 is a hermetically-sealed construction, is fixedly connected with conductive plastic potentiometer on its sidewall, and the rotating shaft end of conductive plastic potentiometer is fixedly connected by the upper end of contiguous block 7 with pendulum 5, and pendulum 5 is provided with obliquity sensor assembly 3; Also be fixedly connected with on the described outer casing inner wall and gather signal processing circuit board 8, gather signal processing circuit board 8 and join with the aviation socket 9 that is arranged on the shell 1.Described obliquity sensor assembly 3 is arranged at the surface level center of pendulum 5.The material of described shell 1 is an aluminium.Described conductive plastic potentiometer 6 is fixed on the shell 1 by installing plate 2.
Obliquity sensor assembly 3 in the utility model is known structure, and it comprises obliquity sensor and corresponding treatment circuit plate.
During use, this device is vertically mounted on the testee by mounting ear 11.When testee is inclined relative to horizontal certain angle, pendulum 5 drives obliquity sensor assembly 3 and still keeps vertical, this moment, conductive plastic potentiometer 6 was according to changes in resistance, can record the inclination angle of pendulum 5 and testee center line, and transfer data to and gather signal processing circuit board 8.Because 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 minute angle measured value that pendulum 5 departs from and is admitted to and gathers signal processing circuit board 8, gather with the detection data of conductive plastic potentiometer 6, obtain the angle value of testee.Finally, high-precision angle value is delivered to upper computer outside by aviation socket 9 with data.
