Abstract

The invention relates to the technical field of instrument and meter detection, mainly applied in detection and law definition of various tilt sensors. A laser tube is fixed on an inclination detection plate, the detection plate is electronically or manually controlled to repeatedly rotate and shift in a measuring range by taking the axis of the detection plate as a center, and the laser tube emits a section of linear horizontal bright line which is scanned and projected on a scale plate which is equidistantly fixed correspondingly surrounding the axis of the detection plate, so that inclination displacement is detected and discriminated according to the position at which the laser ray is anastomotic with the scales of the scale plate. A liquid crystal display (LCD) or a light emitting diode (LED) is used to display an angle and analog quantities, and the analog quantities of various points of the inclination sensor are stored and law defined by using a microcomputer, thereby achieving intelligent detection and law definition of the inclination sensor.

Description

The laser inclinator

Technical field

The present invention relates to the instrument and meter detection technique, the detection rule that is mainly used in various obliquity sensors is fixed.

Technical background

The detection rule of tradition obliquity sensor is fixed to be to use mechanical rocking handle substantially, change displacement through screw rod or gear reduction transmission, uses in addition index dial, sees that the displacement that grating table or scale show notes down; All because the bonding gap of machinery has caused process and return error, also needing of having converts.

Summary of the invention

Laser tube is fixed on the inclination angle detection plate, automatically controlled or manual check-out console is the center at range ability swing offset repeatedly with the check-out console axle center, laser tube penetrates one section in-line horizontal brightness, scan and be incident upon corresponding centering on the equidistantly fixing scaleplate in check-out console axle center, detect resolution inclination angle displacement by the position that this laser beam and scaleplate high scale coincide.

Embodiment

The resolution ratio that detects on demand according to pi is determined the distance of girth and axle center and scale plate, and the computing formula of axle center and scale plate distance: girth ÷ pi ÷ 2 determines scale plate according to detecting the inclination angle scope; For example resolution ratio is 0.1 °, every millimeter scale of scale plate is 0.1 °, 360 ° of girths of circumference are 3600 millimeters, detect the inclination angle scope and be set at positive and negative 45 degree, scale plate effective length and scale are 900 millimeters, the theoretical of 900 scales is 572.9577951 millimeters on axle center and the scale plate, and the scale plate as stainless steel ruler curves arcuation around the axle center and becomes fan-shaped, guarantees that scales all on the scale plate and axle center are all equidistantly fixing; Be 0.05 ° such as resolution ratio, girth is 7200 millimeters, and scale plate effective length and scale are 1800 millimeters, and the theoretical of 1800 scales is 1145.91559 millimeters on axle center and the scale plate; More high-resolution, but the split fixed installation is used.On scale plate according to scale, every 1 ° or 0.5 °, can determine and open by the scale of scale plate as required the loophole of a few tenths of a mm, light-sensitive device is aimed at the laser level bright line at the back side of scale plate through this loophole and is fixed, output logic level when light-sensitive device sensitization, trigger control circuit makes motor stop operating brake time-delay one to several seconds time, delay time changes rear time length adjustment when stable according to obliquity sensor change in displacement output analog quantity thereupon and sets, after record was stored when the analog quantity for the treatment of obliquity sensor output stablize, restarting motor proceeds to detect, detection range by photographic hole quantity and setting detects one by one, but stops when finishing detecting and acousto-optic hint; Can adopt LCD or LED angles of display and analog quantity, with the analog quantity of microcomputer record storage obliquity sensor each point, realize that the intelligent detection rule of obliquity sensor is fixed.

Check-out console by clockwise and anticlockwise motor and rocking handle through screw rod and gear drive, can be automatically controlled or manual dual-purpose, common one to several seconds time rotation displacement once; Determine the size of check-out console according to the profile of detected obliquity sensor, check-out console and gear are fixed on the central shaft, and central shaft is fixed with two axle sleeves or bearing level, and the rotation of assurance axle freely and the non-jitter gap and is connected and fixed with scale plate; Split type check-out console part and scale plate part, respectively fixed installation; Be temporarily fixed at spirit level on the detection plane of check-out console, the calibration of laser inclinator vertically is fixedly mounted on the wall or ground that does not tremble, the laser beam of calibration of laser pipe projection and the detection plane keeping parallelism of check-out console, horizontal zero degree on the detection plane of correct detection plate and the scale plate, but all scale and photographic hole on the laser beam scanning scale plate; Detected obliquity sensor and the spirit level that is used for proofreading and correct all can be temporarily fixed at easily on the detection plane of check-out console and detect, proofread and correct and change.

Claims

1. laser tube is fixed on the inclination angle detection plate, automatically controlled or manual check-out console is the center at range ability swing offset repeatedly with the check-out console axle center, laser tube penetrates one section in-line horizontal brightness, scan and be incident upon corresponding centering on the equidistantly fixing scaleplate in check-out console axle center, detect resolution inclination angle displacement by the position that this laser beam and scaleplate high scale coincide.
