Abstract
The utility model belongs to Fixture designing technology, relates to a kind of stationary fixture for Magnetic testing.The described stationary fixture for Magnetic testing comprises supporting leg, nonferromagnetic supporting plate, baffle plate, fender plate, regulating handle, some parallel mounting grooves for installing baffle plate and fender plate are provided with in the middle of described nonferromagnetic supporting plate, two supporting legs are separately positioned on bottom the two ends of nonferromagnetic supporting plate, wherein, described fender plate is provided with the regulating handle for fore-and-aft distance condition, by the adjustment of regulating handle, detected part is fixed between baffle plate and fender plate.The utility model is used for the risk that hold-down support that Magnetic testing coil method is detected part reduces part gouge, solves the difficult problem that larger part Sectional magnetization cannot realize.The utility model manufactures and designs simply, easy to use, can effectively improve the quality of products.
Description
Technical field
The utility model belongs to Fixture designing technology, relates to a kind of hold-down support being detected part for Magnetic testing coil method.
Background technology
Coil method is detection method relatively conventional in Magnetic testing, for detecting the longitudinal defect of part, is energized by detected part according to wanted detection side in the effective magnetizing region being positioned over coil.Part is magnetized in the magnetic field that coil is inducted, and does not damage part, is very safe detection method, is widely used.But during for the part Sectional magnetization that volume is more complex-shaped, energising moment part is relative to the position meeting play of coil, then detected part is adsorbed on coil firmly, its relative to magnetization effective district position be difficult to ensure, and easy gouge part, generally adopt detection person to use hand retaining element at present, there is very large hidden danger.
Utility model content
The purpose of this utility model is: provide a kind of hold-down support for Magnetic testing coil method, can solve part position unfixed problem when magnetizing.
The technical solution of the utility model is: a kind of stationary fixture for Magnetic testing, it comprises supporting leg, nonferromagnetic supporting plate, baffle plate, fender plate, regulating handle, some parallel mounting grooves for installing baffle plate and fender plate are provided with in the middle of described nonferromagnetic supporting plate, two supporting legs are separately positioned on bottom the two ends of nonferromagnetic supporting plate, wherein, described fender plate is provided with the regulating handle for fore-and-aft distance condition, by the adjustment of regulating handle, detected part is fixed between baffle plate and fender plate.
Supporting leg is provided with the clamp for being fixed on magnaflux guide rail.
Rubber is posted at baffle plate and fender plate and detected feature contacts position.
The utility model has the advantages that: the utility model is used for the risk that hold-down support that Magnetic testing coil method is detected part reduces part gouge, solves the difficult problem that larger part Sectional magnetization cannot realize.The utility model manufactures and designs simply, easy to use, can effectively improve the quality of products.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model for the stationary fixture of Magnetic testing;
Fig. 2 is the use schematic diagram of the utility model for the stationary fixture of Magnetic testing;
Wherein, 1-fender plate, 2-baffle plate, 3-supporting leg, 4-supporting plate, 5-regulating handle, 6-clamp, 7-is detected part, 8-extends conductor, 9-magnaflux coil, 10-magnaflux guide rail.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Refer to Fig. 1, it is the structural representation of the utility model for the stationary fixture of Magnetic testing.The described stationary fixture for Magnetic testing comprises supporting leg, nonferromagnetic supporting plate, baffle plate, fender plate, regulating handle.Wherein, be provided with some parallel mounting grooves for installing baffle plate and fender plate in the middle of described nonferromagnetic supporting plate, this mounting groove is slotted hole, except for except fixed dam and fender plate, can also be used for the discharge of magnetic flaw detection ink.
Described fender plate is provided with the regulating handle for fore-and-aft distance condition, by the adjustment of regulating handle, detected part is fixed between baffle plate and fender plate.
In addition, two supporting legs are separately positioned on bottom the two ends of nonferromagnetic supporting plate, and supporting leg is fixed on magnaflux guide rail by clamp, and the stationary fixture of whole Magnetic testing is fixed on guide rail.
Rubber is posted at baffle plate and fender plate and detected feature contacts position.
Please refer to Fig. 2, it is the course of work of the stationary fixture of the utility model Magnetic testing.Before magnetization, magnaflux coil is roughly moved in the middle part of guide rail, the stationary fixture of Magnetic testing supporting leg is passed from magnaflux coil hollow space, make nonferromagnetic supporting plate across magnaflux coil, adjust two clamps, itself and guide rail are fitted, and the nut screwed on clamp makes the stationary fixture of Magnetic testing be fixed on guide rail.
Detected part is positioned on nonferromagnetic supporting plate according to the direction of magnetization of setting and (prolongation conductor can be put on nonferromagnetic supporting plate in the lump), then according to the approximate location of length adjustment two baffle plates of part, be bolted and baffle plate and nonferromagnetic supporting plate are fixed together, in like manner fender plate is also fixed on nonferromagnetic supporting plate, now note the limited length of adjustable handle, should, as far as possible by close for fender plate detected part, finally by adjustable handle fine setting, detected part be fixed on nonferromagnetic supporting plate.
Larger for size parts classify is become several surveyed areas, mark is carried out with red and blue pencil, mobile magnaflux coil is to part first detected region, magnetic field intensity maximum due to the generation of magnaflux coil is positioned at coil axis center near coil inwall place, along with the increase of the distance of detected part and magnetic field intensity maximum, magnetic field intensity weakens, so concrete effective magnetizing region needs to determine with Shims for Magnetic Particle Testing, test piece is affixed on detected regional magnetic field the weakest point, if the artificial defect in test piece can show, then this surveyed area divides rationally, if artificial defect cannot show or show more weak, then repartition surveyed area, determine each surveyed area by that analogy.
Magnetized moment, the larger magnetic force attracted each other is produced between detected part and magnaflux coil, the stationary fixture of Magnetic testing can ensure that detected part position is fixed, avoid detected part and magnaflux coil coil to produce to clash into or rub and make detected piece surface by gouge, relative position between detected part and magnaflux coil can be ensured simultaneously thus ensure that the effective magnetizing region of Magnetic testing realizes Sectional magnetization.
