[0025] In this embodiment, combined with the Figure 4 As shown, the lateral impact assembly 5 includes a guide rail 51, a slider 52 is slidably connected inside the guide rail 51, a frame 53 is fixedly installed on the rear side of the slider 52, a second cylinder 54 is installed inside the frame 53, a second impact sensor 55 is installed at one end of the output rod of the second cylinder 54, and the detection end of the second impact sensor 55 faces the interior of the testing machine chassis 1.

[0032] How it works

[0033] In the present invention, the automobile parts are placed on the support plate 12 in the test machine chassis 1, and the dual-axis linear motor 11 drives the support plate 12 to move, thereby driving the automobile parts to move. When the support plate 12 moves, the ball 14 contacts and rolls with the bottom of the test machine chassis 1, and the ball 14 and the convex strip 13 support the support plate 12, thereby reducing the pressure transmitted from the support plate 12 to the dual-axis linear motor 11 during impact, thereby reducing the damage to the dual-axis linear motor 11. When the impact is made in the Y-axis direction, the electromagnet 49 has magnetism and attracts the magnetic block 44, the output rod of the first cylinder 46 retracts, and the mounting plate 41 is lifted. When the electromagnet 49 loses its magnetism, The magnetic block 44 is released, and the mounting plate 41 descends along the limiting column 47 through the limiting tube 48, so that the cylindrical protrusion at the bottom of the impact plate 43 impacts the automobile parts, and the first impact sensor 42 detects the impact data, thereby completing the impact test of the automobile parts. When it is necessary to impact in the Z-axis direction, the user holds the handle on the slider 52 to drive the slider 52 to move along the guide rail 51, thereby adjusting the position of the second impact sensor 55 so that the second impact sensor 55 is opposite to the detection position of the automobile parts, and the second cylinder 54 is used to drive the second impact sensor 55 to operate, so as to perform an impact test on the automobile parts.
