Abstract

The invention discloses a hydraulic type universal material testing machine. The hydraulic type universal material testing machine comprises a bottom shell and a motor, wherein a stand column is mounted on the bottom shell; an upper clamp movable platform is mounted on the stand column; a vertical step shaft is mounted on the bottom shell; the step shaft is provided with a lower clamp mechanism through a shaft coupler; a test sample is clamped between the upper clamp movable platform and the lower clamp mechanism; a torque transducer is mounted on the shaft coupler; an inner-thread-free type worm wheel is mounted at the lower end of the step shaft; power of the motor is transmitted to a worm wheel and worm rod mechanism after deceleration and torque increasing through a speed reducer; the worm wheel and the step shaft rotate together so as to drive the lower clamp mechanism to rotate. Meanwhile, the test sample is acted by a torsion moment; the torque transducer is used for measuring torque stressed on the test sample.

Description

technical field [0001] The invention relates to a hydraulic material universal testing machine. Background technique [0002] Existing material universal testing machines can only perform tensile, compression, shear and bending tests of materials, but cannot perform torsion tests. Modern industrial technology advocates energy saving and consumption reduction. How to expand the functions of original mechanical equipment is the direction of efforts of engineering designers, and it is also the historical mission entrusted to scientific and technological workers by the times. [0003] figure 1 Shown is the structural schematic diagram of the tensile working test bench of the existing material universal testing machine, the front and rear two stoppers (3) are connected with the fixed column (9) of the material universal testing machine in the form of pins (2) , to limit the rotational movement of the lower clamp mechanism (8). (When doing the tensile test, start the motor (5) ...
