The conversion structure suitable for the horizontal conversion of the pneumatic impact table to the vertical impact device

Abstract

The invention discloses an assembly structure suitable for a horizontal-to-vertical conversion impact device of a pneumatic impact table. The assembly structure comprises a horizontal hammerhead, a warping plate, a warping plate bracket, compression nuts, a table board, a vertical hammerhead and stand columns, wherein the horizontal hammerhead is fixed on the horizontal plane of the warping plate,and the vertical hammerhead is fixed on the vertical plane of the warping plate, so as to form a conversion structure of the horizontal-to-vertical conversion impact device of the pneumatic impact table; and the warping plate is connected with the warping plate bracket by means of a connecting shaft, the warping plate bracket is fixed on the two nearby stand columns by means of screws on two sides, and the upper part of four stand columns are connected and fixed to the table board by means of threaded rods and the compression nuts. During the test, a hammer body of the pneumatic impact tableapplies a horizontal force to the horizontal hammerhead, the horizontal hammerhead converts the horizontal force into a vertical force by means of the warping plate and the warping plate bracket, andinputs the vertical force to the vertical hammerhead; and the vertical hammerhead transfers the vertical impact force to the bottom part of the table board, so that the table board has the function ofa vertical upward impact force. The assembly structure can exert the impact function when carrying out large-scale pneumatic impact tests of this model or this type, and has the advantages of being safe and reliable, high in universality and saving test costs.

Description

technical field [0001] The invention belongs to the technical field of impact test equipment, and in particular relates to a horizontally converted vertical impact device for a pneumatic impact table. Background technique [0002] In aerospace, aviation, vehicle and other engineering fields, products will work in a certain impact environment, so the impact test is an effective means to test product reliability and dynamic strength, and has been widely used in product performance assessment and dynamic strength appraisal middle. Before completing the high-level vertical impact test of large equipment, it mainly relies on the vertical table of the electric vibration table or the horizontal table of the pneumatic shock table by turning over the tooling. For example, when using a vibrating table for testing, the equipment or product to be carried out is fixed on the moving coil or tooling of the electric vibrating table with screws, and the impact force is transmitted to the pr...
