To ensure the accuracy of the displacement of another parameter of the spring testing machine is the key to ensure the accuracy of the spring test, and also to judge the accuracy of the spring test machine. Therefore, more and more users regard the accuracy of the displacement test as the standard for measuring the level of the test machine. In the national standard of spring testing machine, the requirements of displacement accuracy are very low, which can not meet the requirements of high-rigidity precision spring. Therefore, for testing machine manufacturers, the accuracy of displacement testing must be improved to meet the requirements of users. There are many factors affecting the accuracy of the displacement test, such as the detection method, the structure of the whole machine, the rigidity of the whole machine, the parallelism of the pressure plate, the measuring components, the material, the displacement of the load displacement, etc., as long as these factors are overcome, the guarantee of displacement accuracy is not achieved. questionable. The spring testing machine detects the displacement according to the standard. It can ensure that the spring is placed in different places of the pressure plate and the test force is basically the same. It ensures that within the full range of the test force, any load will not cause the displacement of the load sensor. Shen. In addition, the impact of the spring test machine loading method on the test results can not be ignored. The early loading method is mainly for ordinary AC motor to drive the transmission system, and the loading speed is not adjustable. For elastic components such as springs, due to the presence of resilience stress, the data automatically collected during rapid compression is collected with slow compression or static compression. The data is very different. Nowadays, variable speed systems such as AC servo speed control system are used. By realistically simulating the working state of the spring, the internal stress of the spring in this state is truly measured, which provides a basis for the spring design. With the development of computer technology, the shortcomings of the simple function of the single-chip microcomputer have been improved by the microcomputer. The intelligent function setting expert system, parameter selection, database, clear window Chinese interface, simple mouse operation make the spring test process the most The idealized state is made possible, and the level of intelligence has been greatly improved. The operator can measure and control according to any preset mode with a click of the mouse, and set different test speeds and parameters during the test. The test mode and the whole test process can be controlled according to people's will. The test curve and test data are displayed in real time. The test data can also be calculated, sorted and output according to industry standards or enterprise standards. It can also be used for previous test procedures and tests. The results were queried, and powerful calculations and mathematical statistics replaced the cumbersome work of the past and greatly reduced the amount of labor. In addition, the application of computer network technology will combine the detection control machine (referred to as the lower computer) with the main control machine of the computing center (referred to as the upper computer) to realize the transmission, processing and comprehensive management of test data. The upper computer realizes integrated management of the lower machine group.
