Embodiment Construction

[0017] The process embodiment will be described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0018] Such as figure 1 As shown in the structure schematic diagram of the sample placement positioner of the present invention, a sample placement positioner for a universal material testing machine, the positioner includes a body 1 with a T-shaped structure. The material of the body 1 is No. 45 steel.

[0019] The transverse length of the T-shaped structure of the sample placement positioner can be set arbitrarily, generally as long as it is longer than the length of the standard sample, and the longitudinal length of the sample placement positioner is the standard length, that is, the length from the center of the chuck 2 to its side minus the sample The length from the center to its edge is the longitudinal...

Abstract

The invention provides a universal material testing machine sample placement positioner; the positioner comprises a body; the body has a T-shaped structure. An application method of the universal material testing machine sample placement positioner comprises the following steps: A. adjusting two chucks of the universal material testing machine to obtain a distance longer than a sample to be tested; B. locking the positioner at the side part of the chucks, wherein the transverse part of the T-shaped structure is allowed to tightly adhere to the side surfaces of the two chucks and the vertical part of the T-shaped structure is disposed between the two chucks; C. allowing the sample to be tested to tightly adhere to the vertical bottom of the T-shaped structure, clamping the two chucks, removing the positioner to allow a center line of the sample to be tested to coincide with the center line of the two chucks and to finish the application of the positioner. The positioner of the invention has the following advantages: the sample placing speed and accuracy during performance testing of a material sample are effectively increased, and the testing efficiency and reliability of testing data are increased.

Description

technical field [0001] The invention relates to the technical field of testing mechanical properties of materials, in particular to an auxiliary fixture used for testing mechanical properties of materials and a usage method thereof. Background technique [0002] The universal material testing machine adopts a microcomputer to control the full digital broadband motor servo, drives the precision screw, and performs various modes of automatic control on the test force, displacement and deformation of various product samples through the microcomputer control system to complete the test of the sample. Tensile, compressive, and flexural tests meet the requirements of the national standard GB / T228-2002 "Metal Materials Tensile Test Method at Room Temperature" and other standards. [0003] The main test items of universal testing machine; Elongation at any point, pull-out force, adhesive force and peak value calculation, pressure test, shear peel force test, bending test, pull-out ...
