In the engineering fields of aerospace, aviation, vehicles and the like, products can work in a certain impact environment, so that an impact test is an effective means for testing the reliability and the dynamic strength of the products, and is widely applied to product performance assessment and dynamic strength identification. Before the high-magnitude vertical direction impact test of large equipment is completed, the impact test is mainly completed by an electric vibration table vertical table or a pneumatic impact table horizontal table top through a turnover tool. If when the vibration table is used for testing, equipment or products to be tested are fixed on a movable coil or a tool of the electric vibration table through screws, impact force is transmitted to the products through the movable coil of the vibration table, and the impact magnitude can only reach 400g in an impact test carried out by the electric vibration table due to the self capacity of the electric vibration table. If the turnover tool is used for being carried out on the vertical table of the electric vibration table, not only a plurality of people are needed for matching installation, but also time and labor are wasted, the safety is not high, and the maximum impact magnitude can only reach 1000 g. And large-scale equipment or products cannot be processed by using the overturning tool or on the horizontal sliding table. Therefore, the horizontal conversion vertical impact device suitable for the pneumatic impact table is of great importance to the impact test precision and test safety which have higher magnitude and are larger in equipment or products.
Traditional impact test, when the installation on the perpendicular frock of level commentaries on classics, often need 4 minimum people to install simultaneously, if meet envelope size and reach 600x600x600 mm's product time, installer not only reaches 6 people, still needs the overhead traveling crane cooperation to go on in step with installer, and very easily touch the product when the operation, the time can reach more than 30 minutes. In order to meet the increasingly developing requirements of a large number of spacecrafts and avoid the danger during impact test, an impact device which can be suitable for the pneumatic impact table to be horizontally converted and vertical is urgently needed to be developed.
