Description
Technical field
The utility model relates to a kind of out star wheel magnetic and visits machine, for the magnetic powder inspection of auto parts out star wheel, belongs to magnetic and visits machine technology field.
Background technology
Out star wheel is the critical part in vehicle transmission shaft universal-joint.If out star wheel exists the defects such as the crackle produced because of quality of materials and process, just may there is drive shafts fracture in using, very easily cause the accident of car crash.Therefore defect detecting test must be done to it in the manufacture process of out star wheel.Due to from fracturing mechanics angle, the danger of surface imperfection is more much higher than onesize inherent vice, is therefore applicable to the manufactured factory of magnetic particle inspection apparatus of ferromagnetic materials surface and near surface flaw detection as controlling and ensureing that the important means of product quality generally adopts.For detecting the defect at each position of out star wheel, equipment should have to out star wheel respectively or carry out the ability of circumference, longitudinal magnetization simultaneously, formed during for magnetizing at the same time and rotate or swing magnetic field, collocation normally AC-AC or the AC-DC of magnetization current type.
Because the shape size of out star wheel along axis section differs greatly, out star wheel Internal Spherical Surface also belongs to region of must detecting a flaw, in addition out star wheel output is very big, therefore machine is visited for out star wheel magnetic, how to ensure that its inside and outside surface forms sufficient and uniform magnetic field of trying one's best, the rhythm how adapting to producing in enormous quantities is the problem that needs solve emphatically.
Theory and practice all proves, the inside and outside surface of out star wheel is made to obtain sufficient uniform magnetization, necessarily require that circumferential magnetization device conducts electricity fully, longitudinal magnetizing device has high ampere-turn magnetic potential and workpiece surfaces externally and internally can be imported completely, in the hope of reaching required magnetic field intensity.At present, the domestic magnetic spy machine for out star wheel flaw detection mainly contains following several:
1, horizontal magnetic visits machine: adopt two ends chuck to clamp the little head end of out star wheel and out star wheel Internal Spherical Surface top respectively, the mode of direct indirect current carries out circumferential magnetization, to find the defect that the inside and outside surface of out star wheel is axial: form closed circuit yoke by chuck, guide rail and out star wheel workpiece, galvanic mode is led to the coil be enclosed within the chuck of two ends and carries out longitudinal magnetization, to find the defect of the inside and outside radial surface of out star wheel; This kind of structure, fully can magnetize the inside and outside surface of out star wheel workpiece, but only can manual single feeding, discharge, and rhythm is slow, cannot adapt to requirements of mass production.
2, vertical magnetic visits machine: introduced from Japanese Li Yuan company by Na Tiefu transmission shaft company limited.Out star wheel is vertical to be put, and adopt two ends chuck to clamp the little head end of out star wheel and out star wheel Internal Spherical Surface top respectively, the mode of direct indirect current carries out circumferential magnetization, to find the defect that the inside and outside surface of out star wheel is axial; To the coil indirect current be enclosed within upper and lower chuck, the mode forming alternating current impression magnetic field at surface of the work carries out longitudinal magnetization, to find the defect of the inside and outside radial surface of out star wheel; This kind of structure, by installing automatic feeding, discharge device additional, can realize robotization easily, meeting requirements of mass production; Because out star wheel specification is various, its Internal Spherical Surface depth dimensions differs, and for ensuring enough induced field intensity, must change the lower chuck adapting to the current out star wheel Internal Spherical Surface degree of depth at any time, to make the coil on the downside of out star wheel as far as possible on lower chuck; That is, often change a kind of out star wheel of specification, need dismounting lower chuck once, bring a large amount of workloads to execute-in-place work, and affect the efficiency of continuous working.In addition, owing to longitudinally adopting ac magnetization, affect by exchanging skin effect, magnetic field is more difficult imports to out star wheel Internal Spherical Surface, causes the defect of Internal Spherical Surface clearly not show.
