[0025] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0026] like Figures 1 to 4 As shown, a magnetic field testing device includes a base 1, a control cabinet 2 is arranged on one side of the base 1, a display screen 3 is arranged on the upper end of the control cabinet 2, an adjusting mechanism is arranged on the upper end of the base 1, the adjusting mechanism includes an X-axis screw slide 4, a Y-axis screw slide 5 and a Z-axis screw slide 6, the X-axis screw slide 4, the Y-axis screw slide 5 and the Z-axis screw slide 6 are installed on the upper end of the base 1 in a three-dimensional coordinate system, the parts composition and installation of the X-axis screw slide 4, the Y-axis screw slide 5 and the Z-axis screw slide 6 are the same, a servo 15 is arranged above the Y-axis screw slide 5, an adjusting box 11 is arranged in front of the Z-axis screw slide 6, the internal rotation of the adjusting box 11 is connected to a rotating shaft 13, and the middle outer side of the rotating shaft 13 is fixedly connected to a magnetic field testing head 14.

[0027] Specifically, Figure 1 and Figure 2As shown, the X-axis screw slide 4, the Y-axis screw slide 5 and the Z-axis screw slide 6 are installed on the upper end of the base 1 in the form of a three-dimensional coordinate system. The parts composition and installation of the X-axis screw slide 4, the Y-axis screw slide 5 and the Z-axis screw slide 6 are the same. One end of the Y-axis screw slide 5 is fixedly connected to the first group of motors 7, and the output shaft of the first group of motors 7 is rotatably connected to the first group of screws 9. Two groups of sliding shafts 8 are arranged on both sides of the first group of motors 7. The two ends of the two groups of sliding shafts 8 are respectively fixedly connected to the two ends of the Y-axis screw slide 5, and the outer side of the first group of screws 9 is rotatably connected to the first group of slides 10. The outer sides of the two groups of sliding shafts 8 are slidably connected to the inside of the slide 10. The upper end of the first group of slides 10 is fixedly connected to the X-axis screw slide 4, and the upper end of the support plate 18 is fixedly connected to the Z-axis screw slide 6.

[0028] During operation, the control cabinet 2 is used to control the start motor 7, and the motor 7 drives the screw rod 9 to rotate. Because the motor 7 is rotatably connected to the slide 10, and the sliding shaft 8 is slidably connected to the slide 10, the motor 7 drives the slide 10 to move. Because the X-axis screw slide 4, the Y-axis screw slide 5 and the Z-axis screw slide 6 are installed on the upper end of the base 1 in a three-dimensional coordinate system, a command for specifying coordinates is input in the control cabinet 2. First, the motor 7 in the Y-axis screw slide 5 is started, driving the first group of slides 10 to drive the magnetic field test head 14 to the specified Y-axis coordinate, and then the motor 7 in the X-axis screw slide 4 is started, driving the second group of slides 10 to drive the magnetic field test head 14 to the specified X-axis coordinate, and finally, the motor 7 in the Z-axis screw slide 6 is started, driving the third group of slides 10 to drive the magnetic field test head 14 to the specified Z-axis coordinate. Through the cooperation of the X-axis screw slide 4, the Y-axis screw slide 5 and the Z-axis screw slide 6, the activity range of the magnetic field test head 14 is wider, and the detection efficiency and range are improved.

[0029] like Figures 1 to 4 As shown, a servo 15 is arranged above the Y-axis screw slide 5, an adjusting box 11 is arranged in front of the Z-axis screw slide 6, the interior of the adjusting box 11 is rotatably connected to a rotating shaft 13, and a magnetic field test head 14 is fixedly connected to the outer middle part of the rotating shaft 13, a servo 15 is arranged inside the second group of slides 10, the output shaft of the servo 15 is rotatably connected to a transmission shaft 16, the upper end of the transmission shaft 16 is fixedly connected to a rudder arm 17, and the upper end of the rudder arm 17 is fixedly connected to a support plate 18, the front end of the third group of slides 10 is fixedly connected to the adjusting box 11, a movable groove is arranged on the front side of the adjusting box 11, the rotating shaft 13 is adapted to the movable groove, and a knob 12 is arranged at one end of the adjusting box 11, and the knob 12 is fixedly connected to the rotating shaft 13.

[0030] During operation, after the positional relationship of the magnetic field test head 14 is determined, the control cabinet 2 controls the servo 15 to start, and the servo 15 drives the rudder arm 17 to rotate through the transmission shaft 16. Because the rudder arm 17 is fixedly connected to the support plate 18, and the support plate 18 is fixedly connected to the Z-axis screw slide 6, the magnetic field test head 14 is arranged on the Z-axis screw slide 6. When the rudder arm 17 rotates, it drives the Z-axis screw slide 6 to rotate, thereby driving the magnetic field test head 14 to adjust the lateral angle of the test. Because the knob 12 is fixedly connected to the rotating shaft 13, and the rotating shaft 13 is fixedly connected to the magnetic field test head 14, rotating the knob 12 drives the magnetic field test head 14 to rotate in the movable slot to adjust the longitudinal angle of the test. Finally, the magnetic field test head 14 starts to test the magnetic field data around it, and the magnetic field data is transmitted back to the control cabinet 2 and displayed on the display screen 3. The magnetic field test angles are more and the data are more accurate.
