Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of the design of mechanical testing machines, and particularly relates to a testing machine with a composite angle loading function. Background Art
[0002] The existing mechanical testing machines can only achieve fixed single-angle loading, and the loading platform and the loading actuator are fixed. When the test piece has the requirement of composite angle loading, special tooling fixtures must be designed to achieve composite angle loading. Moreover, the universality of the tooling fixtures is not strong, and special tooling fixtures need to be designed for each test, which puts forward high requirements for designers, and the manufacturing requirements of the tooling fixtures are extremely high. If the manufacturing accuracy of the tooling fixtures is not high, it will seriously affect the authenticity of the test and cannot truly simulate the loaded state of the test piece.
[0003] During the entire test cycle, the design and manufacture of the tooling fixtures will cause the problems of extended test cycle and waste of the tooling fixtures after the test is completed.
[0004] In recent years, domestic mechanical testing machines have been subjected to more composite angle loading tests. These tests are all for a specific test piece, with poor universality and inability to quickly change the loading angle. Summary of the Utility Model

[0013] Preferably, 4 electric telescopic mechanisms are arranged on the bottom surface of the test loading table, and the 4 electric telescopic mechanisms are arranged at the corresponding positions of the four corners of the bottom surface of the test loading table.
[0014] Preferably, the control terminal can calculate the required displacement of each electric telescopic mechanism on the bottom surface of the test loading table according to the test command of the computer and send a loading command to each electric telescopic mechanism on the bottom surface of the test loading table. Each electric telescopic mechanism on the bottom surface of the test loading table performs lifting adjustment according to the loading command and the displacement calculated by the control terminal.
