The accuracy of accuracy directly reflects the comprehensive ability of the universal spring machine, so the accuracy must reach a certain standard, so how do you define the industry's judgment standards?
With the development of computer technology, it makes up for the shortcomings of single chip microcomputer, intelligent function setting expert system, parameter selection, database, clear Chinese window interface and simple mouse operation, make full use of the spring testing process. The ideal state becomes possible, and the level of intelligence has been greatly improved. The operator can measure and control according to any preset mode with a single mouse click. By setting different test speeds and parameters during the test process, the test mode and the entire test process can be controlled according to people's wishes. Real-time display of test curve and test data. It can also calculate, classify and output test data according to industry standards or enterprise standards. It can also test the previous test process and test. Query results, powerful calculation and mathematical statistics functions have replaced the previous tedious work, greatly reducing the amount of labor.
The universal spring machine testing strictly detects displacement according to the standard, which can ensure that the test force of the spring placed in different positions of the pressure plate is basically the same, and any load will not cause the displacement of the load sensor to fall within the entire range of test force. In addition, the influence of the loading method on the test results should not be ignored.
The main requirement of small-load spring machines, especially high-rigidity precision springs, is high test accuracy of the equipment. A small change in displacement will cause a large change in the test force, and it is easy to ensure the test accuracy of the test force. However, ensuring the accuracy of another parameter displacement is the key to ensuring the accuracy of the spring test and is also the standard for determining the accuracy of the spring.
Early loading methods were mainly driven by ordinary AC motors. The loading speed cannot be adjusted. For elastic components (such as springs), due to the springback stress, data collected automatically during fast compression and data collected during slow or static compression are collected. The data is very different. Today, variable speed systems (such as AC servo speed control systems) are used to realistically simulate the working state of a spring. In fact, measuring the internal stress of the spring in this state provides a basis for the design of the universal spring machine.
