Description
Technical field
The present invention relates to a kind of defectoscope more particularly to a kind of fluorescent magnetic particle flaw detector for pipe end.
Background technique
The V-arrangement briquetting of traditional fluorescent magnetic particle flaw detector for pipe end plays positioning and electric action to workpiece.When turning of work piece,
Upper and lower V-arrangement briquetting must be detached from workpiece, and pipe end causes to beat due to rotation, and the interior magnetization center lead rod that can collide with causes to damage；
The lower magnetic pole of traditional defectoscope be it is fixed, can not adjust, and since specification of workpieces is not of uniform size, cause lower magnetic pole sometimes from work
Part is too far.Traditional defectoscope is conductive using center lead rod and external V-arrangement briquetting, is also easy to produce and burns in the generation of steel pipe surfaces externally and internally,
And without interior magnetizing coil, cause pipe end circumferencial direction magnetic efficiency bad.
Summary of the invention
The present invention provides a kind of fluorescent magnetic particle flaw detector for pipe end to solve the above-mentioned deficiency of the prior art.
Above-mentioned purpose of the invention is realized by technical solution below: a kind of fluorescent magnetic particle flaw detector for pipe end, special

Roller mount front end face connects roller fastener, and rear end face is connected with guide rod, and guide rod is inserted into guide sleeve, and roll wheel assembly is fixed on roller mount
On.
The rack is equipped with interior magnetizing coil assembly, and interior magnetizing coil assembly includes fixed plate, adjustable plate, adjusting screw rod
And handwheel, the fixed plate are equipped with block, adjustable plate is equipped with the screw hole of adjusting screw rod, and is fixed with plug, the tune
It saves screw rod upper end and connects handwheel.
Compared with the prior art, the advantages of the invention are
(1) V-type briquetting is changed to realization rotation while compressing of double nylon rollers up and down for front end, to will not cause up and down
It beats in order to avoid causing the damage to workpiece and iron-core coil.
(2) upper and lower magnetic pole is adjustable, makes upper and lower magnetic pole close to workpiece, improves the sensitivity of magnetic powder inspection.
(3) method for not using energization forms composite rotating magnetic field in steel tube surface using logical magnetism method.Not in workpiece table
Face, which generates, burns and the defects of arcing.
(3) interior magnetizing coil solves the magnetic screen of longitudinal magnetization coil, guarantees inner surface magnetic efficiency.
