[0023] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] Example

[0025] Please refer to Figures 1 to 3 As shown, this embodiment provides a non-destructive testing device for the quality of a defective shell, including: a mounting base 1, on which an electromagnetic chuck 3 for fixing a defective shell 7 is mounted via a rotating component. The electromagnetic chuck 3 is surrounded by a first protective component, surrounded by a second protective component, and topped by a third protective component. The defective shell 7 is in direct contact with the third protective component. The electromagnetic chuck 3 generates magnetism to effectively fix the defective shell 7 and ensures that the appearance of the defective shell 7 remains intact after testing, thus achieving non-destructive testing of the defective shell 7.

[0026] The rotating component includes a turntable 2 and a drive motor 8. The top of the mounting base 1 has a mounting groove 101. The drive motor 8 is fixedly installed inside the mounting groove 101. The output shaft of the drive motor 8 is fixedly connected to the bottom of the turntable 2. The electromagnetic chuck 3 is fixedly installed on the top of the turntable 2. By using the drive motor 8 in conjunction with the turntable 2, the electromagnetic chuck 3 can rotate flexibly, driving the differential housing 7 fixed on it to change position at multiple angles. This allows the testing equipment to cover all areas of the differential housing in all directions, improving the convenience of testing.

[0027] The mounting base 1 has a groove 102, and a slider 10 is slidably installed inside the groove 102. The upper end of the slider 10 is fixedly connected to the bottom of the turntable 2. Through the cooperation of the groove 102 and the slider 10, the stability of the drive motor 8 driving the turntable 2 to rotate can be further increased, and the accuracy of the differential detection can be improved.

[0028] The first protective component is a permalloy cover 5, which is fitted and sleeved on the surface of the electromagnetic chuck 3. The second protective component is a silicon steel sheet cover 6, which is fitted and sleeved on the outer surface of the permalloy cover 5. The third protective component is a rubber pad 4, which is fixedly installed on top of the silicon steel sheet cover 6. The permalloy cover 5 utilizes its high magnetic permeability to efficiently concentrate magnetic lines of force, allowing the magnetic field of the electromagnetic chuck 3 to act on the differential housing 7, significantly enhancing the magnetic attraction effect and making the differential housing 7 more secure. Simultaneously, it tightly shields the magnetic field from leakage, preventing interference with surrounding testing instruments and improving the accuracy of the testing results. The silicon steel sheet cover 6 further enhances the magnetic field shielding effectiveness and reduces magnetic field leakage. The rubber pad 4 reduces the risk of field leakage and provides physical protection for the permalloy cover 5, extending the lifespan of the entire magnetic field protection structure, maintaining a long-term stable magnetic field optimization effect, reducing maintenance costs, and ensuring that the magnetic field environment of the detection device is always in excellent condition. The rubber pad 4 directly contacts the differential housing 7, effectively isolating the differential housing 7 from direct contact with the harder silicon steel sheet cover 6 below, avoiding wear on the surface of the differential housing 7, ensuring that the appearance of the differential housing 7 is intact after detection, and realizing non-destructive testing of the differential housing 7. In addition, the rubber pad 4 can also adapt to the microscopic unevenness of the differential housing 7 surface, fill gaps, and make the differential housing 7 fit more tightly with the device, ensuring uniform and stable magnetic attraction of the electromagnetic chuck 3, and indirectly improving the detection accuracy.

[0029] It also includes a controller 9, which is electrically connected to the electromagnetic chuck 3 and the drive motor 8. The controller 9 is a PLC, model 6ES72350KD220XA8. The rotation angle of the electromagnetic chuck 3 can be controlled by the buttons on the controller 9 to meet actual needs and facilitate operation. In addition, the controller 9 can control the opening and closing of the electromagnetic chuck 3 and the magnetic force conveying size, making it easy to use.

[0030] The thickness of the rubber pad 4 is 3-8 mm, the thickness of the permalloy cover 5 is 1-3 mm, the thickness of the silicon steel sheet cover 6 is 1-5 mm, the thickness of the rubber pad 4 is preferably 5 mm, the thickness of the permalloy cover 5 is preferably 2 mm, and the thickness of the silicon steel sheet cover 6 is preferably 3 mm.

[0031] As is well known to those skilled in the art, the working principles and wiring methods of the electromagnetic chuck 3, drive motor 8, and controller 9 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can arbitrarily select and match their models according to their needs or convenience.

[0032] Working principle: When in use, place the housing 7 on top of the rubber pad 4, and energize the coil of the electromagnetic chuck 3 through the controller 9. The electromagnetic chuck 3 generates magnetism to fix the housing 7. In addition, the controller 9 can adjust the current according to the material and weight of the housing 7, so as to precisely control the magnetic strength of the electromagnetic chuck 3, ensuring that the housing 7 is firmly attracted, while avoiding damage to the housing 7 due to excessive attraction.

[0033] By driving the turntable 2 to rotate via the drive motor 8, the electromagnetic chuck 3 can rotate flexibly, causing the differential housing 7 fixed on it to change position at multiple angles, making it convenient for the testing equipment to cover all areas of the differential housing in all directions, thus improving the convenience of testing.

[0034] During the fixing of the differential shell 7, the rubber pad 4 plays a role in buffering and protection, avoiding wear on the surface of the differential shell 7, ensuring that the differential shell 7 is intact after testing, and realizing non-destructive testing of the differential shell 7.
