Description
Technical field
The present invention relates to a kind of longitudinal magnetization device that is used for the bent axle magnetizer, be used for the magnetic powder inspection of 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, 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 longitudinal magnetization device that is used for the bent axle magnetizer, it is characterized in that, comprise motor plate and chain wheel plate, between motor plate and chain wheel plate, be provided with line slideway, motor and driven sprocket are located at respectively on motor plate and the chain wheel plate, on the output shaft of motor, be provided with drive sprocket, at least seven coil stationary framves are located on the line slideway by the carriage of both sides, fixed mount links to each other by telescoping mechanism between any two, vertically be provided with coil on each fixed mount, each coil is from beginning to end again, has finally formed the longitudinal magnetization coil.Drive sprocket links to each other by chain with driven sprocket, and after the drive telescoping mechanism stretched, coil spacing between any two was identical.
Further, two draw-in bars that two outside links that described telescoping mechanism comprises that the end links to each other and end link to each other, the middle-end of outside link and draw-in bar links to each other with described coil stationary frame and makes tensible or contraction between adjacent two coil stationary framves.
Described line slideway is a linear axis, and described carriage is a linear bearing, linear bearing be enclosed within on the linear axis and can be on linear axis move left and right flexibly.
Be provided with mobile screw at described chain near on the described coil stationary frame of outermost end, be fixed with adjustment seat on the coil fixed mount, adjustment seat links to each other with described chain by two set screw.
Multiturn coil of the present invention is that chain by driven by motor drags along the stretching, extension of line slideway and contraction.Coil spread length during automated manner is determined by the limit switch that is contained on the tailstock.The telescoping mechanism of coil makes it in stretching process, and distance is definitely identical between each circle, helps the even of magnetic field.
Advantage of the present invention is once to finish longitudinal magnetization at the bent axle overall length between the 800mm to 1500 for length, makes the magnetization of each position of bent axle sufficient, evenly, and is safe and reliable and failure rate is low.
