When in use, the staff first places the workpiece to be tested into the test seat 401, and when all the workpieces to be tested are placed in each test seat 401 on the turntable 301 respectively , through the setting of the lifting component 200, when in use, by controlling the lifting platform 201 to rise to a certain height, and then by adjusting the base voltage, the magnetic force of the electromagnet in the detection rod 202 is controlled, and the detection rod 202 is adjusted by changing the voltage. When the magnetic attraction between the detection rod 202 and the magnetic block 203 disappears, the magnetic block 203 realizes free fall motion, and the magnetic block 203 is at the upper center of the test seat 401. When the magnetic block 203 falls freely, the workpiece in the test seat 401 can be tested. When the test is completed, the magnetic block 203 is placed back to the magnetic attraction area of ​​the detection rod 202, and then the turntable 301 is rotated by controlling the drive motor 302, so that another test seat 401 is directly below the magnetic block 203, and then the voltage of the detection rod 202 is controlled to realize the next round of testing.

[0028] By using the rotating assembly 300 in conjunction with the test seat 401, the test seat 401 can be rotated. By testing the rotation of the test seat 401, the automated turntable 301 test reduces the need for manual operation, and eliminates the need for staff to repeatedly change the workpiece to be tested, thereby increasing the testing efficiency.

[0029] Second embodiment:

[0030] like Figure 1 , Figure 6 As shown, a limit gear 303 is provided at the output end of the driving motor 302, a limit groove is provided at the bottom of the turntable 301, the limit gear 303 is adapted to the limit groove, and the two are engaged and connected.

At this time, the turntable 301 is installed in the rotation groove.

[0031] By using the driving motor 302 in conjunction with the turntable 301, the test seat 401 can rotate automatically. In actual use, the interlocking connection between the limit gear 303 and the limit groove facilitates the subsequent replacement of the size of the turntable 301. At the same time, the interlocking connection between the two can prevent the driving motor 302 from idling and achieve synchronous rotation of the turntable 301.

[0032] Third embodiment:

[0033] like Figure 4-5 As shown, springs 403 are symmetrically arranged inside the test seat 401, and the springs 403 are fixed in the inner cavity of the test seat 401. The springs 403 are connected to the clamping block 404, and the clamping block 404 is U-shaped. In actual use, the test piece is placed in the clamping block 404 provided in the test seat 401, and the test piece is placed horizontally through the clamping blocks 404 provided at both ends, and then the springs 403 at both ends are used to clamp the test piece.

[0034] By using the clamping block 404 in conjunction with the spring 403, it is possible to clamp detection parts of different sizes. In actual use, this design enables the clamping device to handle products of various sizes, thereby increasing its scope of application.

[0035] Fourth embodiment:

In actual use, through the slider 407 set under the clamping block 404, when the clamping block 404 clamps the detection part, the clamping block 404 will move to both ends of the test seat 401. Through the coordinated use of the set slider 407 and the slide groove, the clamping block 404 will move more smoothly, avoiding the phenomenon of jamming of the clamping block 404.

[0040] Working principle: When in use, the staff first places the workpiece to be tested into the clamping block 404 provided in the test seat 401. The clamping block 404 is inside the convex groove 402. The threaded bolt 405 is adjusted to fix the test piece. Then, the lifting assembly 200 is set. When in use, the lifting platform 201 is controlled to rise to a certain height. Then, the base voltage is adjusted to control the magnetic force of the electromagnet in the detection rod 202. The detection rod 202 is adjusted by changing the voltage to make the magnetic block 203 realize free fall motion. After the magnetic block 203 falls freely, the workpiece in the test seat 401 can be tested. When the test is completed, the magnetic block 203 is placed back in the magnetic area of ​​the detection rod 202. Then, the drive motor 302 is controlled to make the turntable 301 rotate, so that another test seat 401 is directly below the magnetic block 203. Then, the voltage of the detection rod 202 is controlled to realize the next round of testing.

[0041] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
