By simulating a high-temperature environment, a high-temperature test is performed on the product to detect whether it can be used normally in a long-term high-temperature environment.

[0029] The impact simulation component includes a support frame 5, which is fixed to the top outer wall of the workbench 1 by bolts. An electric lifting rod 7 is fixed to the top outer wall of the support frame 5 by bolts. The output end of the bottom of the electric lifting rod 7 can slide through the support frame 5. A fixing frame 6 is installed at the bottom end of the electric lifting rod 7. Multiple groups of air pumps 8 are fixed to the top outer wall of the fixing frame 6 by bolts. Multiple groups of suction cups 4 are provided at the bottom of the fixing frame 6. The suction cups 4 are connected to the air pumps 8.

[0036] When in use, the electric telescopic rod 23 can be used to control the movement of the clamping frame 18. By adjusting the distance between the two sets of clamping frames 18, the product to be tested can be fixed to avoid falling or displacement during the test and rotation heating process.

[0037] To prevent the device from sliding, Figure 2 As shown, a gasket 2 is provided at the bottom of the foot pad 16, and the gasket 2 is made of rubber material;
