Description
Technical field
The present invention relates to field of non destructive testing, particularly to a kind of small takeover inwall Magnetic testing device.
Background technology
Small takeover inwall is done Magnetic testing, tested adapter internal diameter less and adapter longer time, magnetic flaw detection ink without
Method effectively sprays nozzle interior surface, causes and line up part can only carry out Magnetic testing.
With internal diameter it isAs a example by the nozzle inner wall of a length of 1000mm carries out Magnetic testing:
Existing operational approach is for manually to carry out magnetic flaw detection ink spray, and then butt tube magnetizes, and observation is
No existing defects.Owing to the effective range of spray can only arrive two pipe nipple mouths, so Magnetic testing has
Effect monitoring range can only cover adapter mouth.The inwall Magnetic testing of nozzle interior position cannot complete, and makes
Become Magnetic testing unreachable.
Summary of the invention
It is an object of the invention to provide a kind of small takeover inwall Magnetic testing device, solving can only line up
The shortcoming of detection, realizes full pipe Magnetic testing to through-hole parts inwall, has realization quickly spray, magnetization
Properly, comprehensive feature is covered.
In order to realize object above, the present invention is achieved by the following technical solutions:
A kind of small takeover inwall Magnetic testing device, is characterized in, comprises:
Sensing bar magnet, it can extend in tested adapter；
Shower, it is attached to sense on bar magnet, for magnetic flaw detection ink is sprayed onto tested nozzle inner wall；
First magnetization positioning element, is arranged on sensing bar magnet side, and it comprises: the first Internal hole positioning block,
It is successively set on the first longitudinal magnetization coil outside the first Internal hole positioning block and the first circumference energising folder；Institute
The the first Internal hole positioning block stated is arranged at the port position of tested adapter.
This detection device also comprises the second magnetization positioning element, is arranged on sensing bar magnet opposite side, its bag
Contain: the second Internal hole positioning block, be successively set on the second longitudinal magnetization coil outside the second Internal hole positioning block
With the second circumference energising folder.
The first described Internal hole positioning block is arranged on the wherein Single port position of tested adapter, described
Two Internal hole positioning blocks are arranged on the position, another port of tested adapter.
This detection device also comprises suspension ring, and it is connected with one end of sensing bar magnet and is positioned at the first circumference energising
The outside of folder.
Described first Internal hole positioning block and the second Internal hole positioning block use nylon material to make.
The present invention compared with prior art, has the advantage that
1, the present invention can carry out the magnetic powder of full inside pipe wall by shower and supporting detector device butt tube
Detection, solve at ordinary times can only the shortcoming of line up detection, and simple, convenient quick, reduce wave
Take.
2, inconsistent due to tested through-hole parts internal diameter size, hole depth length, therefore different size can be made
The sensing bar magnet coupling of Internal hole positioning block and different length, had both changed conveniently, cost-effective, can realize again
Magnetic testing to many specifications nozzle inner wall.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention a kind of small takeover inwall Magnetic testing device；
Fig. 2 is the sectional view of the present invention a kind of small takeover inwall Magnetic testing device；
Detailed description of the invention
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the present invention is done into one
Step illustrates.
As shown in Fig. 1～2, a kind of small takeover inwall Magnetic testing device, comprise: sensing bar magnet 1, its
Can extend in tested adapter；Shower 2, it is attached to sense on bar magnet 1, for being sprayed by magnetic flaw detection ink
On tested nozzle inner wall；First magnetization positioning element, is arranged on sensing bar magnet 1 side, and it comprises:
First Internal hole positioning block 31, it is successively set on the first longitudinal magnetization line outside the first Internal hole positioning block 31
Circle 32 and the first circumference energising folder 33；The first described Internal hole positioning block 31 is arranged on the end of tested adapter
Mouth position；Suspension ring 4, it is connected with one end of sensing bar magnet 1 and is positioned at the first circumference energising folder 33
Outside.
In a particular embodiment, this device also comprises the second magnetization positioning element, is arranged on sensing bar magnet 1
On opposite side, it comprises: the second Internal hole positioning block 51, be successively set on outside the second Internal hole positioning block 51
Second longitudinal magnetization coil 52 and the second circumference energising folder 53 of side.First Internal hole positioning block 51 is arranged on
The wherein Single port position of tested adapter, the second Internal hole positioning block 51 is arranged on the other end of tested adapter
Mouth position.
With internal diameter it isAs a example by the nozzle inner wall of a length of 1000mm carries out Magnetic testing:
The first, second Internal hole positioning block (31,51) using nylon material to make is stuck in tested adapter two
End, and make sensing bar magnet 1 be positioned at the center position of tested adapter, magnetic flaw detection ink sprays through shower 2
It is spread across nozzle inner wall, then by first and second circumference energising folder (33,53), first and second longitudinal magnetization
Coil (32,52), sensing magnetic 1 rod of long 1000mm tested adapter is carried out AC and DC magnetization and
Exchange demagnetization automatically, makes tested adapter suitably be magnetized, it is achieved the complete opening magnetic to tested nozzle inner wall
Powder detects.If tested adapter is blind hole, then select corresponding sensing bar magnet length according to blind hole depth, only
Need to use the first magnetization positioning element, i.e. by the first longitudinal magnetization coil 32 and the first Internal hole positioning block
31 coordinate, and blind hole can be carried out Magnetic testing.The diameter of Internal hole positioning block, sensing bar magnet length is can
Choosing.
