Abstract
The utility model relates to a permanent magnet flaw detector of a rotary control magnet yoke type. The flaw detector comprises a strong magnetic element, a soft magnetic element, a non-magnetic element, a probe pin, a rotary switch, a press cover and a handle. The flaw detector has the working principle that the strong magnetic element is rotated by the rotary switch; when the rotary switch is in an 'on' state, a S pole and a N pole of the strong magnetic element are in a horizontal direction and just face the soft magnetic element, so that the soft magnetic element is magnetized so as to generate a magnet yoke and the probe pin has the strong magnetic force at the same time, thereby meeting the requirement of flaw detection of magnetic powder; and when the rotary switch is in an 'of' state, the S pole and the N pole of the strong magnetic element just face the soft magnetic element in an up and down direction, so that the soft magnetic element cannot be magnetized to generate the magnet yoke and the probe pin nearly has no magnetic force at the same time, namely, the probe pin can be easily taken from a detected workpiece through a detection operator. The flaw detector has the advantages of being simple in structure, strong in attraction force, low in residual magnetism, easy and convenient to operate, safe and reliable; and the application of electricity and electronic elements is avoided.
Description
Technical field
The utility model relates to field of non destructive testing, and especially one is revolved control yoke formula permanent-magnet flaw detector.
Background technology
Be called magnetic powder inspection with the method for detection of magnetic particle indications workpiece, defect, due to its intuitive display, simple to operate, thereby make it become one of the most frequently used lossless detection method.Because the disconnected magnetic technology of the logical magnetic of permanent-magnet flaw detector is unresolved, during use, therefore cost compared with great strength and it could be taken off from detected workpiece, and easily scratch surface of the work, what therefore extensively adopt at present mostly is magnetic crack detector.But the necessary electricity consumption of magnetic crack detector, and instrument is valuable, easily damage, cable operated inconvenience in tow, inadaptable without electricity or the use of high-altitude dangerous situation.
Through retrieval, existing one " Portable permanent-magnet shielding flaw detector " patented technology, the patent No. is 96251803.4, this patented technology is also failed really from fact solving the disconnected magnetic technology of logical magnetic of defectoscope forever, therefore the same with other permanent-magnet flaw detectors, it operates and deposits all very inconvenient.
Summary of the invention
The purpose of this utility model: for the logical magnetic from fact solving defectoscope forever, disconnected magnetic technology, according to permanent-magnet hang, the principle of work of belt switch magnetic bases, proposed one and revolved control yoke formula permanent-magnet flaw detector.
The utility model is achieved in that
One is revolved control yoke formula permanent-magnet flaw detector, by visiting pin, soft magnetism part, ferromagnetism part, rotary switch, gland, handgrip and non-magnetic member, forms; Visit pin and be arranged on soft magnetism part bottom, ferromagnetism part is arranged in the middle of two soft magnetism parts, and two soft magnetism parts are separated by non-magnetic member, and gland is arranged on soft magnetism part, and handgrip is arranged on soft magnetism part top by handgrip sheet.
Yoke formula permanent-magnet flaw detector is controlled in described revolving, and it is characterized in that: rotary switch can be controlled strong magnetic part and do 90 degree rotations, makes soft magnetism part lead to magnetic, disconnected magnetic.
Advantage of the present utility model: above-described one is revolved control yoke formula permanent-magnet flaw detector, by rotary switch, rotate ferromagnetism part, when rotary switch is during on, the S utmost point of ferromagnetism part, the N utmost point in horizontal direction just to soft magnetism part, the soft magnetism part generation yoke that is magnetized, now visit pin and there is stronger magnetic force, meet the requirement of magnetic powder inspection, when rotary switch is during in of, the S utmost point of ferromagnetism part, the N utmost point is above-below direction just to non-magnetic member, the soft magnetism part generation yoke that is not magnetized, now visit pin and almost there is no magnetic force, testing staff can take off it easily from detected workpiece.This technology has advantages of not electricity consumption, without electronic component, simple in structure, suction is strong, remanent magnetism is low, it is light, safe and reliable to operate.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is left view of the present utility model.
Fig. 3 is cut-open view of the present utility model.
Fig. 4 is component diagram of the present utility model.
In figure, 1 is that spy pin, 2 is that soft magnetism part, 3 is that ferromagnetism part, 4 is that rotary switch, 5 is that gland, 6 is that handgrip, 61 is that handgrip sheet, 7 is non-magnetic member.
Embodiment
As shown in Figure 1, Figure 3, one is revolved control yoke formula permanent-magnet flaw detector, by visiting pin 1, soft magnetism part 2, ferromagnetism part 3, rotary switch 4, gland 5, handgrip 6 and non-magnetic member 7, forms; Visit pin 1 and be arranged on soft magnetism part 2 bottoms, ferromagnetism part 3 is arranged in the middle of two soft magnetism parts 2, and two soft magnetism parts 2 are separated by non-magnetic member 7, and gland 5 is arranged on soft magnetism part 2, and handgrip 6 is arranged on soft magnetism part 2 tops by handgrip sheet 61.
Yoke formula permanent-magnet flaw detector is controlled in described revolving, and it is characterized in that: rotary switch 4 can be controlled strong magnetic part 3 and do 90 degree rotations, makes the logical magnetic of soft magnetism part 2, disconnected magnetic.
Claims (2)
1. revolve a control yoke formula permanent-magnet flaw detector, by visiting pin (1), soft magnetism part (2), ferromagnetism part (3), rotary switch (4), gland (5), handgrip (6) and non-magnetic member (7), form; Visit pin (1) and be arranged on soft magnetism part (2) bottom, ferromagnetism part (3) is arranged in the middle of two soft magnetism parts (2), two soft magnetism parts (2) are separated by non-magnetic member (7), it is upper that gland (5) is arranged on soft magnetism part (2), and handgrip (6) is arranged on soft magnetism part (2) top by handgrip sheet (61).
2. the control yoke formula permanent-magnet flaw detector that revolves according to claim 1, is characterized in that: rotary switch (4) can be controlled strong magnetic part (3) and do 90 degree rotations, makes soft magnetism part (2) lead to magnetic, disconnected magnetic.
