On straight line, characterized in that the center of a pair of cylinders shape coil axis is the gripping apparatus grips of cartridge type part workpiece wait visit
Hurt cartridge type part, clamping device includes a pair of parallel idler wheel rolled around axis, wherein an idler wheel drives equipped with driving motor, separately
One idler wheel is flexibly transported, and the both ends of roller shaft are located on a bracket, and bracket is fixed on the surface of plate, and plate can be perpendicular to one
Cylindrical coil axis direction is moved.
Especially the both ends of roller shaft are supported on bracket by a bearing.
The central hollow position of cartridge type part workpiece and cylindrical coil circle center axial location be equipped with straight stick conductive copper
Item, that is, axis shape electrode；It insulate between straight stick conductive copper bar and cylindrical coil；Straight stick conductive copper bar and a pair of cylinders shape coil point
Do not connect the first power supply and second source, straight stick conductive copper bar and a pair of cylinders shape coil to clamp cartridge type part to be detected a flaw simultaneously into
Longitudinal and periphery magnetic field is generated when row is powered, then magnetic flaw detection ink sprinkling equipment sprays magnetic flaw detection ink to cartridge type part surface, to cartridge type part table
Face carries out spray and detects a flaw.
Straight stick conductive copper bar and a pair of cylinders shape coil power use 12-30V, and current control is in 600-6000A.
One rack installs a pair of cylinders shape coil and makes the central axial line of a pair of of coil point-blank, and therebetween
Away from the length for covering cartridge type part to be detected a flaw；The central hollow position of cartridge type part workpiece be it is poroid, equipped with straight stick conductive copper in the hole in
Item, that is, axis shape electrode, rack are insulating materials preparation, and rack is equipped with the supporting arrangement of axis shape electrode, and axis shape electrode still maintains
In the medium pore of circle copper plate electrode；Magnetic flaw detection ink sprinkling equipment can slide on the sliding rail being equipped with, the spray of magnetic flaw detection ink sprinkling equipment
Leaching outlet is directed at cartridge type part to be detected a flaw.It can be separately equipped with controller, controller controls the pump and spray process, electricity of magnetic flaw detection ink storage box
The application in source, the controller connection magnetization probe.Degaussion coil needs in addition setting to the demagnetization of cartridge type part workpiece.
The electrode plate of cartridge type part magnetic spy wound is powered to cartridge type part, in addition central conducting rod is powered and cartridge type part spiral energization shape
At magnetic field form resultant magnetic field or resultant field together, the multi-direction of cartridge type part can be visited when spraying magnetic flaw detection ink
Wound.
The utility model has the advantages that the utility model is used for large-sized steel cartridge type part magnaflux, it is not necessarily to massive coil, is formed longitudinal
Magnetic field includes Circumferential field, and the magnetic field that especially axial electrode is formed is to need most the flaw detection issuable transversal crack of cartridge type part.
