[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] Please refer to Figures 1-4 The utility model provides the following technical scheme: a wheel hub unit permeable magnetic flux versatility detection equipment, it includes: base 1, the inside installation of base 1 has base 12;The top of wheel hub unit 3 is equipped with probe 4.

[0027] In the embodiment, the bottom end of the base 1 is fixedly installed with a lifting cylinder 11, and the output end of the lifting cylinder 11 is fixedly connected with the bottom end of the base 12. The base is lifted up and down by the lifting cylinder. The mounting seat 2 is lifted up by the lifting cylinder 11, so that the wheel hub unit 3 is close to the probe 4 for scanning.

[0028] The bottom end of the mounting seat 2 is rotatably connected with the base 12. The inside center of the base 12 is fixedly installed with a motor 13, and the output end of the motor 13 is fixedly connected with the bottom end of the mounting seat 2. In the scanning process, the motor 13 in the base 12 is started to drive the positioning die 21 to rotate and combine with the wheel hub unit 3 to realize omnidirectional defect scanning.

[0029] In the embodiment, the mounting seat 2 is arranged at the top end of the base 12. The top end of the mounting seat 2 is provided with a positioning die 21. The two side outer surfaces of the mounting seat 2 are provided with a bolt assembly. The positioning die 21 is fixed by the bolt assembly. The bolt assembly comprises bolts 23 inserted into the two side mounting seats 2. The two side outer surfaces of the bottom block 22 are provided with bolt grooves matched with one end of the bolt 23. The bolts 23 on the two sides of the mounting seat 2 are pulled outwards, so that one end of the bolt 23 is separated from the bolt grooves in the two side outer surfaces of the bottom block 22. The positioning die 21 is removed from the mounting seat 2 for replacement.

[0030] The inside of the mounting seat 2 is fixedly provided with a blocking ring 24 on both sides, and the blocking ring 24 is sleeved on the outer surface of the latch 23. One end of the outer surface of the latch 23 is fixedly provided with a blocking piece 25. The outer surface of the latch 23 is sleeved with a return spring 26 on one side of the blocking piece 25. During outward pulling, the return spring 26 is extruded. When the positioning die 21 is placed into the mounting seat 2, the latch 23 is released, and the return spring 26 pushes the latch 23 inward.

[0031] In this example, the hub unit 3 is placed on the positioning die 21 for positioning, and the bottom end of the hub unit 3 matches the top end of the positioning die 21. The bottom end of the mounting seat 2 is integrally provided with a bottom block 22. The top end of the mounting seat 2 is provided with a mounting groove matched with the bottom block 22. The bottom block 22 at the bottom end of the positioning die 21 is inserted into the mounting groove for installation.

[0032] The working principle of this embodiment is as follows:

[0033] After the hub unit 3 is placed on the positioning die 21 for magnetization, the mounting seat 2 is lifted upward by the lifting cylinder 11, so that the hub unit 3 approaches the probe 4 for scanning. During scanning, the motor 13 in the base 12 is started to drive the positioning die 21 to rotate in combination with the hub unit 3 to realize omnidirectional defect scanning. The scanned image is displayed on the display.

[0034] When it is necessary to replace the corresponding positioning die 21 according to the hub unit 3, the latches 23 on both sides of the mounting seat 2 are pulled outward, so that one end of the latch 23 is separated from the slot on the outer surface of the bottom block 22 on both sides, and the positioning of the positioning die 21 is released. Then the positioning die 21 is removed from the mounting seat 2 for replacement. The corresponding specification positioning die 21 is installed. During outward pulling, the return spring 26 is extruded. When the positioning die 21 is placed into the mounting seat 2, the latch 23 is released, and the return spring 26 pushes the latch 23 inward to position and fix the positioning die 21.
