Abstract
The automatic examine device for defects on bore surface of artillery is composed of detection unit including image sensor and detection frame and control-data processing unit including A/D converter, data acquisition device, buffer and computer system, and features automatic, precise and quantitative examination of defects.
Description
The present invention relates to the defect inspection of metal pipe internal surface, specifically a kind of device that is applicable to that bore defect of cannon detects.
The inspection of thorax in the existing fire bag, a kind of is the industrial endoscope method that adopts pure optical system, and it is similar to medical endoscope, and another kind is the defectoscope system that uses closed-circuit television.The former is made up of eyepiece, lens barrel (perhaps optical fiber biography light beam), all visors, side-view mirror, light source etc., through the biography system that resembles the inner surface optical image is passed to eyepiece by object lens, focuses on the amplification imaging, reaches the purpose of energy visualization inner surface.The latter is the TV image that inner surface is transformed into television eye, delivers to graphics monitor through camera cable and observes.No matter these methods can reach signal to noise ratio with object-image transform itself, the image multiplying power, determining of coordinate position, the function that the kind of drive detects, the way of output of precision, speed and data result all can't improve precision and speed that bore defect of cannon is detected, it checks that the degree of accuracy of defect depends primarily on examiner's experience and level, reliability is low, and efficient is low, and operator's labour intensity is big.
The objective of the invention is shortcoming, provide a kind of detection fire bag bore defect precision height, efficient height, the automatic checking device that the degree of accuracy is high at above-mentioned existence.
The object of the present invention is achieved like this: it comprises test section and control and data processing section, the test section is made up of image sensor and testing stand, and control is made of analog-digital converter, data acquisition, buffer and computer system etc. with data processing section.Lamp house (1) the front end tube wall place that it is characterized in that image sensor is provided with locating ring (3) and stop collar (2), the interior configuration of lamp house (1) can vertically be adjusted displacement and the lamp socket (4) of bulb (5) is housed, and the joint sleeve (9) of lamp house (1) tail end through being used for fixing gamma camera (8) links to each other with the articulation (19) of support ring (10) and spacing ring (20) outside the band; The connecting rod (13) of joint (19) of taking over a job supports to the centre frame (11) of testing stand (12) and goes up and tighten with dop (15), connecting rod (13) connects the electric rotating machine (14) that is controlled by operating desk by gear reduction unit, and the screw pair (16) affixed with dop (15) connects the length travel motor (18) that is controlled by operating desk by screw mandrel (17); The picture intelligence that provides by connecting rod (13) inner cable line, connect computer system through the analog-digital converter of control and data processing section and data acquisition, buffer and go here and there input/output interface.
Adopt of the automatic inspection of this device to defect in the cannon thorax, for comprehensive, accurate, quantitative understanding cannon thorax inner surface situation and Changing Pattern provide may, changed in the past low accuracy method by visual estimation.Advantages such as it is reliable and stable to have device, easy for operation.But quick identification is judged the defect kind, and high accuracy detects the defect physical dimension, the position angle, and image shows, takes pictures, print data result.It is applicable to the automatic inspection of various metallic interior surface defects.

Cannon thorax inner surface is a complicated curved surface, curvature difference not only, and can its candlestick chart difference in height be also different, effectively detect various defects, and obtaining available picture intelligence is an individual key link.The defect of metal surface mainly all is that relative normal surface has the projection depression on certain deviation on the form, the formation texture variations that has, and the difference that shows as smart rugosity that has, these projection depressions form at specific illumination and direction of observation.The metal surface is good reflector, no matter whether deformation all has very high reflectivity.Resulting scattered light intensity just can obtain available picture intelligence in defect metamorphosis scope.According to the different suitable image sensor parts of selection that need of tested artillery lumen size.When tested artillery lumen internal diameter during greater than Φ 75mm, the interior lamp socket of lamp house (1) (6) adopts screw thread mouth with being connected of bulb (5), and used bulb is 60W; When interior thorax internal diameter is Φ 57～Φ 75mm, the interior lamp socket of lamp house (1) (4) adopts bayonet socket with being connected of bulb, and used bulb is 2 18W, when interior thorax internal diameter is Φ 25～Φ 57mm, the interior lamp socket of lamp house (1) (4) adopts bayonet socket with being connected of bulb (6), and used bulb is 18W; On the sidewall of lamp house (1), have air vent (5); In order to detect thorax top and terminal needs in the workpiece, can add to two locating rings respectively at the image sensor two ends.The model of used CCDTV gamma camera is IK-M32, and the joint sleeve place corresponding with gamma camera (8) optical lens has logical light window (7), guarantees that the reverberation of measured surface videotapes imaging on the machine side through optical system at CCD.But image sensor compound motion of straight-line displacement and swing rotation in the thorax in workpiece, be to adopt two reaction stepping motors to drive, stepper motor is a kind of control motor that the arteries and veins signal is become straight-line displacement or angular displacement, the command pulse number (being provided by operation keyboard) that its displacement strictness equals to import can accurately be located.The model of used two stepper motors is respectively 75BF003 and 110BF01, and it is to carry out strict control by the pulse signal that the control and the computer system of data processing section provide.The picture intelligence that cable in connecting rod provides send into control with data processing section digital to analog converter (A/D) input, the pulse digital signal that its output provides by data acquisition, buffer (TMM2016) and interface board to computer (IBMPC286) system.Computer is realized processing to data with the digital image signal gathered through software program.
The work that software section is finished is: 1. device operation control automatically, just control the operation of motor, and make gamma camera obtain the image of artillery lumen any position.2. image data acquisition is handled the given and image recognition of answer signal, asks the Breadth Maximum of view picture image live width, line length distribution, line, and area etc. are finished image recognition.Be used for display simulation spirogram shape with the supporting monitor of gamma camera, also can show digital image.The display supporting with computer shows operation degree and data processed result, can the result be got through typewriter.
