The eddy current plane inclination and flatness detection device disclosed by the utility model can effectively avoid the limitation on an environment by a light source of an optical plane detection device based on an electromagnetic principle.
Description
Technical field
The utility model relates to a kind of pick-up unit, particularly a kind of current vortex plane inclination and flatness checking device.
Background technology
Present stage commercial production with the life in used high level of accuracy instrument apparatus majority detect based on optical principle.Because receive the restriction of light source to aspects such as environmental requirement and instrument size majority are bigger than normal, the plane detector that present stage adopts is inconvenient to detect on the spot.
Summary of the invention
Use this novel disclosed a kind of current vortex plane inclination and flatness checking device, comprise amplifier 1, analysis process system 2 and test circuit 3, said test circuit 3 is connected to analysis process system 2 through amplifier 1.
Said test circuit 3 comprises ferromagnetism bead 4, hot-wire coil 5, inductance sensor, and is parallelly connected with inductance sensor, parallelly connected with power supply again after said ferromagnetism bead 4 is connected with the hot-wire coil 5 of both sides.
Test circuit 3 comprises power supply, resistance Z1, resistance Z2, ferromagnetism bead 4, hot-wire coil 5, after the connecting of said ferromagnetism bead 4 and both sides hot-wire coil 5, is two resistance in series Z1, Z2 parallel connection, and is parallelly connected with power supply again.
One end of said amplifier 1 inductance induction connects ferromagnetism bead 4, and the other end connects resistance Z1, the continuous circuit of Z2.
Current vortex plane inclination and flatness checking device principle of work are following: when there was certain degree of tilt in detection plane, the probe portion ferromagnetism bead of device will move to produce a section than downside accordingly.Because bead is former in respectively causing both sides coil inductance value that different variations takes place with coil near side.Bead increases near the coil inductance value of a side, and reduces away from the coil inductance value of a side.Through inductance sensor the inductance variable quantity of two lateral coils is gathered, and delivered in the analysis process system through amplifier.Analysis process system through the inductance after two lateral coils are changed compare, analyze bead on the curved surface displacement after mathematical computations, can obtain the angle of inclination on plane again.Change the sensitivity that the radius of bead can modifier, and change the degree of accuracy that bead " track " curvature can modifier.
The utility model has been avoided the restriction of the light source of optical flat pick-up unit to environmental requirement effectively based on the electromagnetics principle.On the other hand, the sensor in this device, amplifier and analysis process system and additional result show, can realize through using integrated circuit, have significantly reduced device size, can be easy to carry, and can realize detecting on the spot.
