Multifunctional material mechanics testing machine with functions of tension torsion and pressure torsion

Abstract

The invention relates to a material mechanics testing machine, belonging to the technical field of the material mechanics testing machine. The material mechanics testing machine is characterized in that the upper end and the lower end of the stander are provided with a lift motor and a torsion motor; the two motors form into one set of dynamic loading system and are controlled as well as coordinated to realize a tension torsion test and a pressure torsion test by an external electrical control system; a guide screw is arranged between the work table and an upper beam, wherein the upper end of the guide screw is fixed at the upper bean, and the lower end of the guide screw is driven by a synchronous belt wheel in a connection way; a middle beam is arranged between the work table and the upper beam; the middle beam is respectively provided with a tension compression rod and a tension compression sensor as well as a torsion sensor, wherein the tension compression sensor and the torsion sensor are communicated with a computer; the upper part of the wok table is provided with a slide way with a slide pillow; one side of the work table, near the vertical rod, is provided with a support seat; and the lower part of a torsion reduction machine is fixedly provided with a hanging rod, wherein the lower part of the hanging rod is provided with a clamp head. The two motors in the one set of dynamic loading system are simultaneously coordinated and controlled by the electrical control system to realize the functions of tension torsion and pressure torsion, and the rotate speeds of the two motors are adjusted by the electrical control system to meet the requirement of different experiments, digitally process the collection and the transmission of a parameter to be tested, and truly and exactly display the parameter on a screen.

Description

1. Technical field [0001] The invention relates to a material mechanics testing machine and belongs to the technical field of material mechanics testing machine structure. 2. Background technology [0002] At present, the existing material mechanics testing machines can only perform tension, compression, bending torsion, torsion, cantilever beam bending, simply supported beam bending and other tests. They lack the function of tension and compression torsion tests. When the tension and torsion tests need to be carried out, When carried out simultaneously, we can only conduct separate tests and then conduct theoretical derivation, and the real test data of tension and compression cannot be obtained. 3. Contents of the invention [0003] The object of the present invention is to solve the deficiencies of the above-mentioned prior art and provide a test device that can not only perform tests such as tension, compression, bending and torsion, torsion, cantilever beam bending, s...
