Summary of the invention
The purpose of this utility model is to overcome above deficiency, and a kind of piston clamping device for detecting flaw is provided, and this device can significantly alleviate the phenomenon of the not firm and easy sparking of Workpiece clamping.
The utility model solves the technical scheme that its technical matters adopts: this clamping device comprises static housing, longitudinal coil II, closed circuit iron core, closed circuit iron core shifting roller, longitudinal coil I, electrode axis I, clamping cylinder I, air cylinder support, clamping cylinder III, clamping cylinder II, electrode axis III, electrode axis II, the mobile box roller, mobile box, speed reduction unit, carrier wheel, tooth bar, handwheel, be furnished with a circular electric pole axis and two semicircular electrode axles on closed circuit iron core, electrode axis I is circular, electrode axis II, electrode axis III is semicircle, the upper supporting clamping cylinder I of electrode axis I, the upper supporting clamping cylinder II of electrode axis II, the upper supporting clamping cylinder III of electrode axis III, clamping cylinder I, clamping cylinder II, clamping cylinder III is separately fixed on air cylinder support, and the flaw detection workpiece is positioned at electrode axis I and electrode axis II, between electrode axis III, mobile box coordinates with closed circuit iron core by closed circuit iron core shifting roller, longitudinal coil I is fixed on mobile box, longitudinal coil II is fixed on static housing, mobile box is provided with the mobile box roller, and handwheel is connected with speed reduction unit, and speed reduction unit connects carrier wheel, carrier wheel is meshed with tooth bar, has formed a kind of piston clamping device for detecting flaw.
The utility model solves the know-why that its technical matters adopts: this piston clamping device for detecting flaw is a hold assembly on the piston defectoscope, holding workpiece when detecting a flaw.Holding action relies on clamping cylinder I, clamping cylinder II, clamping cylinder III to promote respectively circular electric pole axis I and two semicircular electrode axle II and electrode axis III and realizes.After the flaw detection workpiece is clamped, passes to vertical circumferential electric current the flaw detection workpiece is magnetized, and spray magnetic flaw detection ink.According to the magnetic powder inspection principle, after having the flaw detection workpiece of surface or near surface flaw to be magnetized, the magnetic line of force in ferromagnetic material flaw detection workpiece by the time, meet the ferrimagnet surface, near surface flaw forms the magnetic line of force and spills----stray field.When defect direction and magnetic direction when angled, variation due to the magnetic permeability of fault location, magnetic line of force effusion surface of the work, produce stray field, stray field attracts the magnetic heap-shaped to become magnetic trace absorption magnetic to form the magnetic trace, the fault location absorption magnetic of flaw detection workpiece forms the magnetic trace amplified, thereby completes magnetic powder inspection.
Beneficial effect: clamping cylinder I, clamping cylinder II and clamping cylinder III work simultaneously, guarantee that like this fork-shaped workpiece clamp obtains firmly, are difficult for sparking, and have guaranteed the magnetization effect.And the flaw detection carriage be stationary structure can make workpiece in magnetic history to greatest extent by effective magnetizing, can significantly reduce undetected phenomenon.
