Abstract

The utility model relates to a device, in particular to a well type magnetic powder flaw detection device of a coupler yoke. The flaw detection device is characterized in that a silicon steel sheet electrode axis passes through left and right coils; a left bar-penetrating cylinder and movable coil unit and a right bar-penetrating cylinder and movable coil unit sleeve the silicon steel sheet electrode axis; a first excitation supply input end is on the left bar-penetrating cylinder and movable coil unit; a fourth excitation supply input end is on the right bar-penetrating cylinder and movable coil unit; an up-down coil is above and below a left-right coil; a front-rear coil is in the front and at the rear of the left-right coil; a fifth excitation supply input end is on the left-right coil; a second excitation supply input end is on the up-down coil; a third excitation supply input end is on the front-rear coil. Because of the technical scheme, the well type magnetic powder flaw detection device of the coupler yoke disclosed by the utility model has the advantages and active effects that a well type structure is formed by the three sets of coils, a spatial rotary magnetic field is formed by the coils, and after the coupler yoke enters the magnetic field, surface magnetic field energy can be uniformly distributed; cracks can be clearly displayed, and the well type magnetic powder flaw detection device is high in anti-interference capability and has good magnetizing and demagnetizing effects.

Description

Car coupler yoke well formula magnetic powder inspection device

Technical field

The utility model relates to a kind of device, particularly a kind of car coupler yoke well formula magnetic powder inspection device.

Background technology

At present, for this complex-shaped workpiece of car coupler yoke, detect a flaw with common magnetic powder inspection device, can form Magnetic field inhomogeneity, can not clear demonstration crackle, the weak consequence of antijamming capability, easily cause undetected.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of car coupler yoke well formula magnetic powder inspection device is provided, and the space rotating magnetic field that can produce with upper and lower, left and right, six of front and back coil, concentrates on car coupler yoke in all directions, and it is carried out to magnetic powder inspection.

The utility model solves the technical scheme that its technical matters adopts: the utility model is by siliconized plate electrode axis, excellent cylinder and moving coil are worn in a left side, the first excitation supply input end, upper and lower map, front and back map, left and right map, the second excitation supply input end, the 3rd excitation supply input end, the 4th excitation supply input end, excellent cylinder and moving coil and the 5th excitation supply input end composition are worn in the right side, it is characterized in that: siliconized plate electrode axis is through left and right map, and excellent cylinder and moving coil are worn in a left side, excellent cylinder is worn on the right side and moving coil is through in siliconized plate electrode axis, wear on a left side the first excitation supply input end on excellent cylinder and moving coil, wear on the right side the 4th excitation supply input end on excellent cylinder and moving coil, the upper and lower of left and right map has upper and lower map, map before and after the front and back of left and right map have, on the map of left and right, there is the 5th excitation supply input end, on upper and lower map, have the second excitation supply input end, on the map of front and back, have the 3rd excitation supply input end.

Owing to adopting technique scheme, advantage and good effect that the utility model has are: adopt three groups of coil compositions well type structured, the inner space rotating magnetic field that forms, after car coupler yoke enters, its Surface field can be uniformly distributed, do not need to contact car coupler yoke, just can carry out disposable resultant magnetization simultaneously.The clear demonstration crackle of energy, antijamming capability is strong, and magnetization, demagnetization are effective.
