Abstract

The invention provides a pneumatic impact table. The pneumatic impact table comprises a table board assembly, an impact cylinder assembly and a shell, wherein the impact cylinder assembly is arrangedin the shell; the impact cylinder assembly comprises an outer cylinder, an inner cylinder arranged in the outer cylinder, an upper impact cylinder cover and a lower impact cylinder cover. The upper end parts of the outer cylinder and the inner cylinder are sealed through the upper impact cylinder cover; the lower end parts of the outer cylinder and the inner cylinder are sealed through the lower impact cylinder cover; the table board assembly comprises a working table board, a piston rod connected to the lower portion of the working table board, and a piston head connected to the lower end ofthe piston rod. The piston rod penetrates through the upper impact cylinder cover; the piston head is arranged in the inner cylinder in an up-down moving mode, an inner cavity of the inner cylinder isdivided into an inner cavity upper portion located on the upper side of the piston head and an inner cavity lower portion located on the lower side of the piston head by the piston head, and a plurality of vent holes are formed in the side wall of the upper end of the inner cylinder.

Description

technical field [0001] The invention relates to the impact test of the mechanical environment test technology, in particular to a pneumatic impact table. Background technique [0002] The impact table test equipment is mainly used in the mechanical environment test of the product. By simulating the impact environment that the product may suffer during use, loading and unloading and transportation, the functional reliability and structural integrity of the product under this impact environment are assessed. [0003] Conventional vertical impact test equipment mainly adopts the method of free fall. Its working principle is that the test piece is installed on a table, and a certain lifting mechanism is used to lift the work table to a certain height, and then release the table, so that the table and the test piece fall freely together. Go to the chopping board where the waveform generator is installed to generate the desired shock waveform. From the time when the platform fall...
