Problems solved by technology

[0002] The local magnetization device is a commonly used device in the eddy current flaw detection of the quality of ferromagnetic tubes and bars in the metallurgical industry. It is used to magnetize the workpiece to be inspected and improve the sensitivity of eddy current detection. The existing local magnetization device has the following shortcomings: the length of the lower support base is too short, The probe and coil are suspended at the front end, causing the equipment to tilt to one side during storage and installation; the probe is under the magnetized coil, and it is inconvenient to operate when replacing the probe and magnetic shoe, and it is difficult to control the gap and axis of the probe, magnetic shoe and workpiece. The size range of the workpiece to be detected is small; the structure of the lifting part of the cylinder requires high processing and installation precision. If the processing and installation are not in place, it is easy to cause jams; the rollers at both ends of the magnetic arm are not positioned, and it is difficult for the workpiece to Keep in line with the axis of the probe and magnetic shoe

Embodiment 1

[0026] Example 1, such as figure 1 , 2 , 3, and 4, a local magnetization device includes a base 1, a lateral adjustment plate 2, a pillar 3, a threaded transmission shaft 4, a lifting bracket 5, a yoke 6, a cylinder 7, a magnetization coil 8, a magnetic shoe 9, and a probe Fixed adjusting frame 10, guide wheel 11 are characterized in that:

[0027] The horizontal adjustment plate 2 is fixed on the upper surface of the base 1, and the lateral adjustment movement of the horizontal adjustment plate 2 on the upper surface of the base 1 is controlled by adjusting the adjustment mechanism on the horizontal adjustment plate 2;

[0028] There are two pillars 3, which are vertically fixed on the upper surface of the horizontal adjustment plate 2 side by side;

[0029] The threaded transmission shaft 4 is vertically fixed on the upper surface of the lateral adjustment plate 2 between the two pillars 3, the top of the threaded transmission shaft 4 is fixed with a hand wheel 40, and the...

Embodiment 2

[0036] Example 2, such as Figure 5 , 6 As shown, further, the cylinder 7 is fixed on the lifting bracket 5, the piston rod 70 of the cylinder 7 is downward, and the moving direction of the piston rod 70 of the cylinder 7 is parallel to the pillar 3; the yoke 6 is fixed on the piston below the cylinder 7 The top 71 of the rod 70, the pillar 3 passes through the yoke 6, the two arms 60 of the yoke 6 are perpendicular to the pillar 3, the cylinder 7 controls the yoke 6 to move back and forth along the pillar 3 through the piston rod 70, and the piston rod 70 of the cylinder 7 moves downward When the yoke 6 is fixed below it, the cylinder 7 controls the reciprocating movement range of the yoke 6 to be small, which can be used to detect workpieces with small diameters.
