Portable nondestructive detecting instrument of laser speckle tire and detection method thereof

Abstract

The invention discloses a portable nondestructive detecting instrument of a laser speckle tire and a detection method thereof. The detecting instrument disclosed by the invention comprises a driving mechanism and a detection mechanism which are mutually independently arranged, wherein the driving mechanism comprises a motor, a reduction gear, a driving wheel, a positioning rod, a pushing hand, anidler wheel and a rotating shaft; the motor and the reduction gear are connected and arranged at one end of the rotating shaft; the pushing hand is arranged at the other end of the rotating shaft; the pushing hand is in a U-shaped structure; the positioning rod is arranged between the U-shaped side of the pushing hand and the driving wheel; the detection mechanism comprises a detection head and atriangular bracket; the detection head is arranged on the triangular bracket; and the exterior of the detection head is connected with a computer. The detection method disclosed by the invention comprises the following steps: dividing the tire into multiple sectors; respectively shooting the tire surface section and tire side of each sector before and after pressurization; and analyzing the obtained picture, thereby judging the conditions of the breakage, actual bulge or air bubbles of the steel wire in the tire. The detecting instrument disclosed by the invention adopts a pressurized mode toload; and compared with the prior art, the detecting instrument is convenient to use, has the advantage of simpleness in operation and can be better suitable for the outdoors or the condition that the tire is installed on a vehicle.

Description

technical field [0001] The invention relates to the technical field of tire detection, in particular to a portable laser speckle tire non-destructive detection instrument and a detection method thereof. Background technique [0002] The utility model patent with the patent No. ZL 200420102848.7 discloses a laser speckle tire non-destructive testing instrument. The testing instrument is installed in a testing room equipped with a vacuum device, and is connected with a vertical, horizontal and rotational movement mechanism through the detection head movement mechanism. Laser speckle detection head; below the detection head is an automatic tire positioning device for carrying and positioning tires; on the side wall of the detection chamber, there is a door that can be opened and closed. The non-destructive testing method is carried out with the detector, and the laser speckle tire non-destructive testing device can detect internal defects of tire products, and can be applied to...
