Description
Technical field
The present invention relates to a kind of crankshaft magnetic and visit machine, be used for the magnetic powder inspection of length≤1500mm crankshaft of diesel engine.
Background technology
Diesel engine is the heart of the vehicles such as automobile, tractor, boats and ships and power-equipment, and bent axle is the vitals of diesel engine, during diesel engine work, and bent axle high speed rotating, transmission power.If there are defectives such as crackle on the bent axle because of quality of materials and process generation, in the use just crankshaft breakdown and machine failure may take place, jeopardize personal safety, cause economic loss.Therefore in the manufacture process of bent axle, must do defect detecting test to it.Because from the fracturing mechanics angle, the danger of surface imperfection is more much higher than onesize inherent vice, is applicable to that therefore the magnetic powder inspection equipment that ferromagnetic materials surface and near surface flaw detect is generally adopted as control and the important means that guarantees product quality by bent axle manufacturing plant.And for the diesel engine repairing department, configuration magnetic is visited machine and is visited carrying out magnetic at the labour bent axle, can detect issuable fatigue crack in its use, provides reliable basis for can it continue to install to use, and gives security for continuing safe handling.
For detecting the defective at each position of bent axle, equipment should have to bent axle carry out respectively or simultaneously circumferentially, the ability of longitudinal magnetization, form rotation or swing magnetic field for can magnetize at the same time the time, the collocation of magnetization current type is AC-AC or AC-DC normally.
Because of king journal, connecting rod neck and the crank throw of bent axle not on same axis, demagnetizing field is big during longitudinal magnetization, and along bent axle vertically the shape and the size of each section also differ greatly, therefore crankshaft magnetic is visited machine, how to guarantee that its each several part surface obtains sufficient and the uniform longitudinal magnetization of trying one's best is the problem that need solve emphatically.
Theory and practice all proves, because the bent axle shape causes the big cause of demagnetizing field, at first require the longitudinal magnetization device to have high ampere-turn magnetic potential, adopt yoke formula longitudinal magnetization device as equipment, then the bent axle that surpasses 800mm for length will not reach required magnetic field intensity along the centre of length quite on a large scale.Both at home and abroad the longitudinal magnetization device than large crankshaft is mainly contained at present: 1, moving coil: monocoil operating distance is limited, and coil can be moved in orbit, and bent axle must segmentation magnetization and flaw detection.Such as internationally famous German KARL DEUTSCH UHS1500 machine and TIEDE 120GW machine promptly is that so high ampere-turn coil moves with electronic or manual mode.This device helps each several part and obtains sufficient longitudinal magnetization, but efficient is lower, also is not suitable for the work of using PLC auto-programming.For making each surface longitudinal magnetic field as far as possible evenly, coil generally adopts the ac magnetization electric current.
2, the open-close type coil of multiturn: the big current coil of multiturn is uniform along bent axle, and every circle coil is with the pneumatic mode synchronous on-off.This device helps each several part and obtains sufficient longitudinal magnetization, also helps the work of using PLC auto-programming, for making each surface longitudinal magnetic field as far as possible evenly, generally adopts the ac magnetization electric current.But since during the energising of big electric current folding switch because of very easily distortion of heating, the easy-to-draw arc-welding in coil opening and closing place is lived or can not conducting, equipment failure rate is very high, this device seldom adopts.
3, spacial special-shaped coil, this is the patent of German KARL DEUTSCH company, but can the said firm only be used for this kind coil detecting the UH series magnetic spy machine than small workpiece, be used for large-scale bent axle spare, and effect is worth querying.
Summary of the invention
The purpose of this invention is to provide a kind of bent axle overall length that surpasses 800mm for length and once finish the device of longitudinal magnetization or resultant magnetization, make each position magnetization of bent axle sufficient, evenly, safe and reliable and failure rate is low.
In order to achieve the above object, technical scheme of the present invention has provided a kind of crankshaft magnetic and has visited machine, comprise main frame body and switch board, on the guide rail of the support assembly of fuselage, be provided with head, tail frame chuck clamping energising circumferential magnetization device, left side headstock chuck base is fixed, the position of right side tailstock chuck base can move and lock according to crankshaft length, is equipped with behind the tailstock chuck to clamp the cylinder that bent axle is used, and is equipped with the chuck current-carrying plate that bent axle is clamped the back energising on the head, tail frame collet axis.Be respectively equipped with electric cabinet and equipment Pneumatic controlled box in the left and right sides of support assembly.It is characterized in that being provided with can longitudinally extending multiturn longitudinal magnetization coil, is provided with the workpiece wheelwork on the chuck current-carrying plate between the head, tail frame chuck.
