Impact testing device

Abstract

The invention discloses an impact testing device which comprises an impact assembly, a supporting assembly and a measuring assembly. The impact assembly comprises a cylinder body, a piston and a driving device, and the piston is connected with the driving device through a sleeve; a breather pipe is arranged in the sleeve; the sleeve is sequentially sleeved with a ring sleeve and a cylinder cover, and a vent hole matched with the vent pipe is formed in the ring sleeve; a spring is further arranged at the lower end of the cylinder cover, and an air inlet, a first supporting table used for bearing the cylinder cover and a second supporting table used for bearing the spring are arranged in the cylinder body. By arranging the impact assembly and the measuring assembly, the piston can repeatedly and accurately perform impact test on the workpiece, and the kinetic energy condition of the piston is obtained through the test block, so that the test efficiency and the test accuracy of the silica gel product are improved; and by arranging the cylinder body and the driving device, the speed before the piston makes contact with the workpiece is conveniently controlled, it is guaranteed that the impact assembly can impact the workpiece at the preset speed, and the production yield of silica gel products is guaranteed.

Description

technical field [0001] The invention relates to the technical field of silica gel product production, in particular to an impact testing device. Background technique [0002] In the process of production and development of sealing rings, before mass delivery of products of different materials and different specifications, it is necessary to conduct experiments under simulated working conditions to guide the design and development and confirm that the products meet the requirements. At present, the experimental equipment generally adopts the impact test by means of drop weight and pendulum. These test devices all have the problems of slow test speed and long experimental period. Due to the direct drive impact method, it is often impossible to rebound naturally after the impact test is completed, and there is a problem that the contact time of the impact is difficult to accurately control, and the working conditions of the product cannot be fully simulated, resulting in a larg...

AI Technical Summary

Problems solved by technology

At present, the experimental equipment generally adopts the impact test by means of drop hammer, pendulum, etc., and these test devices have the problems of slow test speed and long test period.

Due to the direct drive impact method, it often cannot rebound naturally after the impact test is completed, and there is a problem that the contact time of the impact is difficult to accurately control, and the working conditions of the product cannot be fully simulated, resulting in a large measurement error of the impact energy and affecting the seal.
