3. Electronic Testing Machine System Composition, Working Principle, and Testable Items
3.1 The system consists of three main parts: the host, the electrical control system, and the digital control system.
3.2 Working Principle
3.2.1 Principles of Mechanical Transmission
3.4 Standard Test Items: (Standard Display Values and Calculated Values)
● Tensile Stress ● Tensile Strength
● Tensile Strength ● Elongation at Break
● Tensile Stress
● Tensile Strain Rate
● Tensile Stress Value ● Tearing Strength
● Any point force value ● Any point elongation rate
● Extraction Force ● Adhesion and Peak Value Calculation
The Yangzhou Jingzhao tensile machine mainframe consists of a motor and controller, ball screw, guide column, moving beam, limit switch, etc.
Four, the sequence of mechanical transmission is as follows:
Motor - Timing Belt Pulley - Lead Screw - Test Bench
4.2.2 Force Measurement System: A tensile sensor is mounted on the movable beam of the main unit, with its lower end connected to the upper clamp. During the test, the force on the specimen is converted into an electrical signal by the force sensor and input into the microcomputer acquisition and control system.
4.2.3 Automatic Extension Tracking Device: This device is used to measure sample deformation, consisting of two tracking clamps with minimal resistance that are held on the sample. As the sample is subjected to tensile force and deforms, the distance between the two tracking clamps also increases accordingly. The tracking clamps convert linear motion into rotational motion through a rope and pulley, and the displacement is converted into an electrical signal input into the microcomputer acquisition and control system via a tracking encoder.
4.3 Limiting Protection Device and Clamp
4.3.1 Limiting Protection Device
The limit protection device is an integral part of this machine. The main unit is equipped with a fixed limit bar, which is fitted with two adjustable collars that can move up and down. During the testing process, when the stopper and collar collide, it will cause the limit bar to move, thereby actuating the limit protection mechanism.
Cut off the passage in this direction, the main unit will stop running. At this point, running in the opposite direction will allow the test machine to operate normally. Adjusting the position of the stopper on the limit rod can limit the travel of the moving beam, providing great convenience and a reliable safety protection for conducting tests.
4.3.2 Clamp
Our company offers a variety of universal and fixture clamps for holding samples, including wedge jaw clamps, wrapping wire clamps, film stretching clamps, and paper stretching clamps, etc. These are capable of meeting the holding requirements for performance tests on different materials such as sheets, strips, foils, strips, wires, fibers, plates, bars, blocks, ropes, fabrics, and meshes, and can be customized according to customer needs.
V. Installation and Commissioning of Electronic Testing Machines
5.1 Mechanical Installation
Position the main unit vertically at the usage location, adjust the ground screws at the bottom of the main unit, and check the worktable level with a level (longitudinal and lateral levelness of 0.2/1000).
5.2 Electrical Installation
5.2.1 Plug the force sensor connector into the force sensor interface and the displacement sensor connector into the displacement sensor interface.
5.2.2 Once the aforementioned work is completed, the system can be powered on. There is a boat-shaped switch on the back panel of the microcomputer collection system. Place the switch in the 'on' position to connect the power.
5.2.3 Connect the main power supply, then rotate to engage the power switch.
5.2.4 The microcomputer system must be preheated for 20 minutes after power-on before it can operate normally.
Section 6: Instrument Usage and Operation
6.1 First, check and confirm that the main machine of the testing machine and the microcomputer control system's cable connections are correct and error-free.
6.2 To stop or shut down the main power of the rotating ejection tester (press the "Emergency Stop" button), press the "Emergency Stop" button when an urgent stop or shutdown is required. Turn on the power of the microcomputer control system.
Section 7: Electronic Testing Machine Accessories

7.2 One set of standard tensile testing machine fixtures will be randomly included (other fixtures available for selection).
7.3 One set of tensile testing machine software.
A set of brand-name computers, one color printer
Section 8: Precautions for Electronic Testing Machines
8.1 Before powering on, check the connections, plugs, sockets, and power plug sockets between the CNC system and the main unit for correctness or looseness. Power on only after confirming they are correct (e.g., a loose ground wire under the power socket in the CNC system controller can cause the main unit to lose control). Remember the power-on sequence: first, turn on the main power of the test machine, then the CNC system power. When shutting down, turn off the main power of the test machine first, then the CNC system power. Do not remove any plug after powering on.
8.2 It is crucial to check the position of the upper and lower limit position retaining rings, ensuring a certain distance between the clamps to prevent damage to the machine components due to incorrect operation or loss of control of the main unit, especially the sensors.
8.3 Do not press any keys on the microcomputer control system during the testing process.
8.4 Select the fixture based on the specific test conditions to avoid damaging the fixture.
8.5 In the event of a sudden power outage, please immediately shut down all power sources and only restart them in sequence after confirming stable power supply. Frequent multiple interruptions in power supply can easily damage the microcomputer control system and the motor speed control system.
8.6 During the operation of the main unit, the test personnel should not stay far from the machine.
8.7 The input tensile speed value must match the actual tensile speed of the testing machine, especially during tearing and peeling tests.
8.8 Do not perform tensile tests when the break force value of the unclear sample is not specified, otherwise the sensor may be damaged due to overload.

9.1 The test software under Windows XP operating system can achieve control modes such as fixed load, fixed displacement, and fixed time to meet various testing requirements.
9.2 The test software supports random switching between Simplified Chinese, Traditional Chinese, and English languages.

9.7 Test results can be automatically saved and manually saved.
After the 9.8 test, you can print batch sample and individual sample data and graphical reports.
