Performance principle description of dedicated testing machine:

Introduction to Testing Machine 1

This machine is mainly used for detecting the torque of spiral springs and tension wheels. The tested part is installed between two clamp heads with adjustable space, and by changing the fixture, it can adapt to different tests on the torsional mechanical properties of the tested part. The testing machine adopts computer-controlled operation and can perform fixed angle torque testing; Display the angle torque curve of the tested part on the monitor; Real time display of angle, torque, torsional speed, peak torque retention, and testing machine operating status; Storage of experimental data, printing of experimental reports, etc.

2 Scheme Description

2.1 Host

The host adopts a horizontal structure. The right end torque disk is connected to the sensor, which is the fixed end, and the left end is the rotating end. The load is driven by a Panasonic AC servo motor imported from Japan through a gapless reducer to drive the force plate to rotate. The torque is transmitted to the torque disk end through sample loading to detect the torque. The loading system can move and fix along the guide rail to adjust the test space.

2.2 Transmission System

By using Panasonic motors and drivers from Japan, the wide range of speed continuous adjustment and uniform loading during the testing process are ensured;

2.3 Detection of torque and torsion angle

Using high-precision torque sensors, torque can be measured in both forward and reverse directions; The detection of torsion angle adopts a photoelectric encoder (matched with the motor), and the detection of angle is on the output shaft to ensure the authenticity and effectiveness of the displayed angle. By using a computer data acquisition and processing system, the sensor and encoder signals are processed and displayed on the computer screen.

2.4 Measurement Control System:

The torque measurement and control system consists of a high-precision bidirectional symmetrical torque sensor, a voltage regulator, a measurement amplifier, and an A/D converter; The torsion angle measurement control system consists of a photoelectric encoder, a frequency doubling shaping circuit, a counting circuit, etc. Through various signal processing, computer control, data processing, display and other functions are achieved.

2.5 Experimental Process

Manual operation part: For the convenience of fine adjustment when clamping workpieces, there are slight forward and reverse buttons near the chuck of the main machine, which are convenient for the operator to use.

The entire experimental process adopts the Chinese human-computer dialogue mode of the WINDOWS platform, using a graphical window based operating system. The experimental parameters are input by the keyboard, and virtual buttons are operated by the mouse to automatically complete the entire experimental process. The screen displays torque, angular displacement, test speed, torque angular displacement curve, and the working status of the testing machine.

The experimental results can be stored in a computer.
