Embodiment Construction

[0078] The details of the present invention and specific implementations thereof will be further described below with reference to the accompanying drawings.

[0079] see Figure 1 to Figure 14As shown, the four-axis centering adjustment system and method for a biaxial tensile testing machine of the present invention solves the problem that the coaxiality of the loading chain of the existing biaxial testing machine needs to be disassembled and the loading chain cannot be adjusted in real time. To a certain extent, it fills the gap of the existing technology; the adjustment amount reaches 0.01mm / grid, and the adjustment range is ±0.5mm, ±0.35°; the biaxial alignment sensor can identify the five freedoms such as the coaxial, angle, and torsion of the loading chain At the same time, the verticality of the two axes in the orthogonal direction and the flatness of the axes can be analyzed, and the detection accuracy is 0.01mm; the coarse adjustment device can be used to limit the po...

Abstract

The invention relates to a four-axis centering adjustment system and method for a biaxial tensile testing machine, and relates to the technical field of testing machines. It includes the main shaft loading chain, the centering adjustment device, the centering sensor and the feedback device, and the frame. The centering adjustment device is installed on the main shaft loading chain, the main shaft loading chain is installed on the frame, and the detection and feedback mechanism is installed on the frame. Used to detect and control adjustments. The advantages are: the adjustment of five degrees of freedom can be realized, and the precision matches the detection device; the invention is connected with the loading chain of the whole machine, which improves the strength of the whole device and reduces the damage to the loading shaft. The system has strong adaptability and can be matched with different Form of loading chain and various types of fixtures, small space occupation, simple operation, high repeat adjustment accuracy, improve experimental accuracy, and make measurement data more accurate.

Description

technical field [0001] The invention relates to the technical field of testing machines, in particular to a four-axis centering adjustment system and method for a biaxial tensile testing machine. The concentricity of the loading chain can be calibrated on the testing machine. Background technique [0002] With the development of the economy and the advancement of science and technology, the testing machine industry has sprung up like mushrooms after a spring rain, and various testing machines for different purposes are emerging. Dynamic unbalance and other aspects, and are more and more widely used in machinery industry and other fields. The traditional method of adjusting the coaxiality of the testing machine is manual adjustment, but the efficiency of manual adjustment is low, and the standards are different, and the adjustment amount is limited, which is easy to cause damage to the testing machine, substandard accuracy, poor stability and other results. A four-axis cent...
