Vertical impact tester

Abstract

The invention discloses a vertical impact tester which comprises a base frame module, an impact body module, a quick clamp module and at least one inertia triggering module .The base frame module forms a base framework of the vertical impact tester, and at least two guide shafts are longitudinally and vertically arranged in the base frame module .The impact body module comprises a movable carrier plate and a punch installed at the lower end of the movable carrier plate, and the movable carrier plate is connected with the guide shafts through linear bearings .The quick clamp module is installed on a bottom plate on the lower portion of the base frame module, opposite to the punch and used for holding an elastic workpiece to be subjected to impact testing .The inertia triggering modules are installed on the movable carrier plate .The impact body module impacts the elastic workpiece, rebounds and then triggers a locking action, and the impact body module is locked to the base frame module so as to prevent the impact body module from repeatedly colliding with the elastic workpiece .According to the technical scheme, modular design is adopted, the impacting action can be automatically locked after impact testing so as to prevent the elastic workpiece from being impacted twice or many times, and accuracy of testing is guaranteed.

Description

technical field [0001] The invention relates to the technical field of free-fall vertical impact testing equipment, in particular to a vertical impact testing machine. Background technique [0002] In the industry of plastic and other elastic material products, it is usually necessary to test the strength, toughness and other properties of plastic products to determine whether the products meet the specification requirements. The various testing machines currently used for testing strength and toughness almost inevitably have secondary or multiple impacts, because plastic products have certain elasticity, after the impact force is applied to the plastic product, the plastic product absorbs the impact force and changes For the elastic force, the impact body rebounds, so that the impact body falls on the plastic product again after leaving the plastic product, causing secondary or multiple impacts, which affects the accuracy of the test. This requires a fast, simple, accurate,...

Problems solved by technology

[0005] This patent can test different products or multiple products at the same time, and has a buffer mechanism, but it is still difficult to achieve the function of locking the impact action after the impact. Naturally, there is the problem of secondary or multiple impacts, and it is difficult to effectively guarantee the accuracy of the test data. accuracy
