Combined torque and axial force testing machine

Combined torque and axial force testing machine

The equipment is currently a high-strength bolt manufacturer, automobile manufacturer, bolt fastener, engineering quality inspection agency, steel structure construction unit, engineering supervision agency, high-speed railway, bridge power, scientific research and experimental institute, commodity inspection and arbitration, technical supervision department, wind power photovoltaic, factory and mining enterprises, engineering machinery, power tower It is the most popular high-strength bolt testing instrument with low investment and high return for scientific research institutions such as petrochemical industry and colleges and universities.

The tester is mainly used for the detection of high-strength bolt connection pairs. It can detect, display and print the axial force, torque and torque coefficient of large hexagon high-strength bolt connection pairs and torsional shear high-strength bolt connection pairs. The equipment is automatically loaded by cycloidal pinwheel reducer, linear guide rail, full Chinese operation interface, microcomputer controlled automatic tightening, loosening and resetting of high-strength bolts, intelligent prompt during operation, and convenient and fast operation. When the axial force reaches the standard setting value, the tester will automatically record the test data, automatically calculate the average axial force, average torque, average torque coefficient, standard deviation and coefficient of variation of the sample through the computer, and display the output torque coefficient, axial force curve, torque curve, etc. At the same time, it has the functions of parameter setting, calibration, data report printing and query.

Structural characteristics

1. The height of the host adopts the human-machine design principle, which is convenient to operate.

2. The bolt torsion-pull installation test module is installed on the linear guide rail, and the installation and adjustment of the test piece is convenient.

3. Easy software design, the test process is completed with one button.

4. The lower end of the main machine body is equipped with a tool box, which makes the work of test operators more convenient.

5. The input end is loaded at a constant speed by a reducer, which greatly improves the consistency, repeatability and authenticity of the experimental results.

6. The surface of the host has been treated with anti-corrosion and antirust treatment, and the design life of the equipment is long, and the host has high rigidity and fatigue strength; The electronic control components have good heat dissipation conditions and stable performance, and will not burn the integrated circuit board at high temperature.

7. The horizontal floor structure is adopted, and the whole machine is made of thickened steel plate to ensure the high rigidity of the main machine. AC servo motor, reducer, coupling, high-precision two-way torsion sensor, pressure load sensor, axial force tension device, etc. are on a central axis, and the coaxiality is ≤ 0.2mm, so that no lateral torque and axial force will be generated during bolt torsion；

Fixture

1. It adopts high-quality alloy structural steel, which is processed and produced in strict accordance with the following technological requirements: blank pretreatment - machining - normalizing - finishing - quenching - grinding, and has the characteristics of high machining accuracy and good fit size, so as to meet the tensile and torsional requirements of Grade 8.8-12.9 high-strength bolts;

2. The unique fixture special shape design fully meets the tension and torsion test of small size bolts (such as 55mm in length), and also ensures the service life;

3. The principle of optimization design is adopted to make the tooling lightweight design. Under the condition of meeting the requirements, the weight is reduced to achieve convenient operation and reduce labor intensity;

4. The heat treatment process needs to be heated in a vacuum furnace, which can not only ensure that the heat treatment is not deformed, but also can not be oxidized, decarburized and other characteristics, can not only ensure high hardness, but also ensure the toughness of the fixture, meet the requirements of large size bolts to bear tension and torque, and greatly extend the service life;

5. Fixture installation and disassembly is convenient and fast, which can realize single person rapid installation and test, and has automatic alignment function. There is positioning device between each workpiece, which reduces labor intensity；
