After the automobile parts to be tested are fixed, the electric telescopic rod 2 drives the partition mesh plate 3 to reset. After closing the safety cover door 7, the automobile parts to be tested are subjected to a pressure-resistant blasting test in the test chamber. The principle of the blasting test bench body 1 is the prior art and will not be repeated here. After the test is completed, the electric telescopic rod 10 with The cleaning rod 6 is moved, and the cleaning rod 6 can scrape off the debris adhering to the horizontal end of the safety cover door 7 during the movement. After the safety cover door 7 is cleaned, the cleaning rod 6 is reset, and the safety cover door 7 is opened by the servo motor 11 or opened manually. During the opening process of the safety cover door 7, the electric telescopic rod 12 drives the partition mesh plate 3 to move upward. During the movement of the partition mesh plate 3, the debris adhering to the inner wall of the test chamber is scraped off to achieve the cleaning of the inner wall of the test chamber until the bottom of the partition mesh plate 3 is flush with the bottom of the cleaning rod 6. At this time, the electric telescopic rod 2 10 is re-extended to gather the debris on the partition mesh plate 3, which is convenient for cleaning the debris.
