Abstract

The invention discloses a device for eliminating deformation interference of a testing machine frame, which includes a multifunctional support, the multifunctional support includes a first connecting plate, a second connecting plate and a plurality of vertical plates, the first connecting plate is fixed Set on the upper beam of the testing machine frame, the second connecting plate is fixed on the testing machine frame at the testing machine workbench, the top of each vertical plate is connected with the first connecting plate, the vertical The bottom end of the plate is fixed with a self-adjusting screw that is slidingly matched with the second connecting plate, and the self-adjusting screw is sleeved with two springs that are located on both sides of the second connecting plate; one of the vertical A vertical scale grating is fixed on the board, and a grating reading head for reading the scale on the scale grating is connected to the movable beam of the testing machine through a connecting frame. The device for eliminating the deformation interference of the testing machine frame of the invention has simple structure and convenient operation.

Description

technical field [0001] The invention relates to the technical field of metal detection equipment, in particular to a device for eliminating deformation interference of a testing machine frame. Background technique [0002] Material testing machine is one of the commonly used equipment for applying deformation to materials. In order to facilitate the installation and testing of unidirectional tension or compression specimens, the testing machine mostly adopts a wide two-column frame structure. The wide structure brings sufficient installation space, but It will also bring a certain nonlinear frame deformation problem, which will affect the loading accuracy of the test specimen. In addition, the servo motor is decelerated by a two-stage synchronous belt, and the ball screw is used to convert the rotation into the translational movement of the movable beam. Because both the synchronous belt and the ball screw have motion gaps, it is very difficult to precisely control the defo...
