Abstract
The utility model provides an auxiliary magnetization frock, is including the magnet that charges that is used for putting through circular telegram conductor, wherein, it is provided with a plurality of recesses that are used for placing the part that awaits measuring to charge the magnet upper surface, the recess is on a parallel with magnet length direction, and the central axis of the part that awaits measuring is located the notch of recess, the opening direction perpendicular to magnet lower surface is charged to the opening direction of recess notch, and the electric current of circular telegram conductor is from charging the magnet and forming circumferential magnetic field, effectively realizes the circumference magnetization to subminiature part, simultaneously because the part can a plurality of combinations arrange and evenly distributed at the conductor near-surface, so can once only magnetize a plurality of parts to improve magnetization efficiency and detection speed.
Description
Technical Field
The utility model relates to the technical field of magnetizing devices, in particular to an auxiliary magnetizing tool.
Background
When magnetic powder detection is carried out on ultra-small parts (the diameter of the part is less than 8 mm), a common magnetizing mode is generally adopted: the direct electrifying method is characterized in that a part is clamped between two contact plates of a magnetic particle flaw detector, so that a current passes through the part to form a circumferential magnetic field for detecting the defect parallel to the current direction, but aiming at the ultra-small part appearing in the actual detection field, the clamping force between the contact plates of the flaw detector is larger, the difference between the undersize contact surface of the part and the area of the contact plates of the flaw detector is several times or even tens of times, so that the part is easily crushed, the end surface of the part is not completely attached to the contact plates during clamping, the part is easily burnt due to local overheating of the end surface of the part, the length of the ultra-small part is limited to be not large compared with the width of a human finger, the operation of a detector is extremely inconvenient, and the risk that the finger is crushed exists.
SUMMERY OF THE UTILITY MODEL
The utility model provides an auxiliary magnetizing tool to solve the problems in the background art.
The technical problem solved by the utility model is realized by adopting the following technical scheme:
the utility model provides an auxiliary magnetization frock, is including the magnet that charges that is used for putting through circular telegram conductor, wherein, it is provided with a plurality of recesses that are used for placing the part that awaits measuring to charge the magnet upper surface, the recess is on a parallel with magnet length direction, and the central axis of the part that awaits measuring is located the notch of recess, the opening direction perpendicular to magnet lower surface is charged to the opening direction of recess notch, and the electric current of circular telegram conductor is from charging the magnet and through forming circumference magnetic field to detect the defect of part surface that awaits measuring.
In the utility model, the magnetizing body is a cuboid-shaped block and is made of pure copper.
In the utility model, the notch of the groove is a wave-shaped notch, and the size of an upper bottom opening of the wave-shaped notch is larger than that of a lower bottom opening of the wave-shaped notch.
In the utility model, the notch of the groove is a trapezoidal notch.
In the utility model, the size of the opening of the notch can be adjusted to a certain extent according to the size of the cross section of the part to be measured, but because the magnetizing tool is used as a current conductor to generate a circumferential magnetic field, the size of the circumferential magnetic field can be changed, the central axis of the part to be measured is positioned in the notch as much as possible according to actual requirements, a gaussmeter is used for measuring the actual magnetic field size of the outer surface of the part to be measured, and then magnetizing parameters of the part are adjusted correspondingly. .
Has the advantages that: the electrified conductor generates a circumferential magnetic field to magnetize a part to be detected positioned on the magnetizing body, so that circumferential magnetization of the subminiature part can be effectively realized, and meanwhile, as a plurality of parts can be combined and arranged and uniformly distributed on the near surface of the conductor, a plurality of parts can be magnetized at one time, so that the magnetization efficiency and the detection speed are improved.

Fig. 2 is a sectional view taken along line a-a in fig. 1.
Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further explained below by combining the specific drawings.
Referring to fig. 1 ~ 2 supplementary frock of magnetizing, including the magnetization body 1, recess 2 and the wave type notch 3 that are used for putting through the circular telegram conductor, wherein, 1 upper surface of magnetization body is provided with the recess 2 that is on a parallel with length direction, just the notch of recess 2 is wave type notch 3, 1 lower surface of the magnetization body of opening direction perpendicular to of wave type notch 3, simultaneously the last end opening size of wave type notch 3 is greater than bottom size down, and in the wave type notch 3 was arranged in to the part that awaits measuring, the electric current of circular telegram conductor was from the magnetization body 1 through forming circumference magnetic field to detect the defect of the part surface that awaits measuring.
In this embodiment, the magnetizing body 1 is a rectangular parallelepiped block made of pure copper.
In this embodiment, the upper surface of the magnetizing body 1 is provided with a plurality of grooves 2, so that a plurality of parts can be detected at one time.
In this embodiment, the notches of the grooves 2 are trapezoidal notches.
In this embodiment, certain adjustment can be made according to the size of the part cross section that awaits measuring to the opening size of wave type notch 3, nevertheless because the frock of magnetizing is produced the size of circumference magnetic field as circular telegram conductor and probably is changed, so should make the central axis of the part that awaits measuring be located wave type notch 3 as far as possible according to actual demand, and need use the gauss meter to measure the actual magnetic field size of the part surface that awaits measuring, do corresponding adjustment to the parameter of magnetizing of part again.
