[0045] Embodiment three

[0046] The automatic falling ball test equipment provided in embodiment one is further optimized, and specifically, as shown in Figure 3 The middle of the mobile rotating platform 2 is provided with an air suction pipeline 10, the upper end of the air suction pipeline 10 penetrates through the upper end face of the mobile rotating platform 2, and the lower end of the air suction pipeline 10 is connected with a negative pressure air suction pump; through negative pressure vacuumizing, the falling ball clamp 3 can be adsorbed on the mobile rotating platform 2, so as to avoid random sliding.

[0047] The use process of the automatic falling ball test equipment is as follows:

[0048] The falling ball clamp 3 in which the test sample 4 has been placed is centrally placed on the mobile rotating platform 2, a "adsorption" instruction is input, the air suction pipeline 10 will suck air to stably adsorb the falling ball clamp 3 on the mobile rotating platform 2, so as to prevent the falling ball clamp 3 from moving in the test process.

[0049] The drawing of the test sample 4 is imported into the host computer 11, and the positions of the test points required are marked in the graphic software. Such a sample needs to be tested at 9 points, the points are marked as follows on the drawing, and there are test order numbers (such as Figure 5 The positioning laser head 8 on the equipment will automatically find the test position in advance on the physical object of the test sample 4 and store it.

[0050] The test height value is input in the host computer 11, and the falling ball lever arm 6 will move to the corresponding height along the vertical moving track 5.

[0051] The steel ball 9 is held and placed at the electromagnet 7, and the electromagnet 7 sucks the steel ball 9. At this time, the steel ball 9 blocks the positioning laser head 8, and when the laser head senses that the light is blocked for 3 seconds, the coil of the electromagnet 7 is de-energized, so that the steel ball 9 freely falls and hits on the corresponding test point.

[0052] When the first point is tested, the computer is pressed Enter key, and the moving rotating platform 2 is quickly moved and rotated to move the next test point to the position directly below the laser head, so as to complete the whole test process. As shown in the following figure, Figure 6 For testing No. 1 point, Figure 7 For testing No. 4 point, Figure 8 For testing No. 5 point.
