Abstract
The invention discloses a flatness detecting device based on an information fusion technology, belonging to the technical field of measurement. According to the flatness detecting device disclosed by the invention, mercury is injected in a hollow glass ball; a mercury level is used as a reference face in the measurement; and the glass ball and a plane to be detected are in point contact. No matter how the hollow glass ball is placed, the internal mercury level keeps unchanged relatively to the height of a lowest point of the glass ball, so that the mercury level accurately represents the height change on the point on a plane of a working platform. A measuring method disclosed by the invention has less needed hardware; the calculation amount is small; and the precision and the detection efficiency in flatness detection can be improved.
Description
Technical field
The invention belongs to many information fusion detection technique field, be specifically related to a kind of flatness checking device based on information fusion technology.
Background technology
Existing large plane flatness detects mainly to be measured by hand, and the low low precision of efficiency, can not meet the requirement of suitability for industrialized production fast detecting.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of flatness checking device based on information fusion technology is provided, its object is automatical and efficient measurement plane degree, and can be by data automatic recording in computing machine.
Flatness checking device based on information fusion technology provided by the invention, it is characterized in that: generating laser (6) is a word linear laser transmitter, and fixing with nut (4), ccd video camera (5) is parallel with generating laser (6) to be also fixed on nut (4), nut (4) can move up and down along the guide rail (2) on column (1), leading screw (3) is axial connection the with servomotor (11) through bearing (7), bearing (7) is fixed on column (1), column (1) is vertical with base (10) and be fixed together, foot screw (12) is housed under base (10), a word laser beam maintenance level that regulates foot screw (12) can make generating laser (6) launch, ccd video camera (5) and servomotor (11) respectively by data line with notebook computer (8) to being connected.Hollow glass ball is equipped with mercury in (9), and the surface level of mercury is as reference field, and hollow glass ball is positioned in tested plane (13).By notebook computer (8), control servomotor (11) rotation, drive leading screw (3) rotation, nut (4) is moved up and down along guide rail (2), be used for adjusting generating laser (6) and be radiated at the laser beam on glass bead, laser beam is overlapped with mercury face, column (1) is equipped with the displacement that grating scale records nut (4), and when laser beam overlaps with mercury face, the displacement of nut (4) is exactly the relative height that hollow glass ball (9) is located the upper point of tested plane (13).
Accompanying drawing explanation
Accompanying drawing is the structural representation of the flatness checking device based on information fusion technology.
Embodiment
The generating laser (6) that apparatus of the present invention adopt is a word linear laser transmitter, and fixing with nut (4), ccd video camera (5) is parallel with generating laser (6) to be also fixed on nut (4), nut (4) can move up and down along the guide rail (2) on column (1), leading screw (3) is axial connection the with servomotor (11) through bearing (7), bearing (7) is fixed on column (1), column (1) is vertical with base (10) and be fixed together, foot screw (12) is housed under base (10), measure the height of adjusting foot screw (12) while starting, the word laser beam maintenance level that generating laser (6) is launched.
Hollow glass ball is equipped with mercury in (9), and the surface level of mercury is as reference field, and hollow glass ball is positioned in tested plane (13).No matter how hollow glass ball is placed, the distance of the mercury the horizontal plane glass bead minimum point in glass bead remains unchanged, so the pin-point accuracy of mercury surface level has reflected the height of detected plane upper glass ball placement location point.
The position of measuring nut place while starting is relative zero-bit, by notebook computer (8), control servomotor (11) rotation, drive leading screw (3) rotation, nut (4) is moved up and down along guide rail (2), be used for adjusting generating laser (6) and be radiated at the laser beam on glass bead, on computer screen, observe and detect the image that ccd video camera gathers, laser beam is overlapped with mercury face, and the displacement that now nut moves is mercury face with respect to the height of zero-bit.
Nut is returned to zero bit position, movable glass ball is to other point in tested plane, height according to above step duplicate measurements mercury face with respect to zero-bit, calculates the flatness of tested plane by all height values that measure with least square fitting.
