Description

Technical Field

[0001] The utility model relates to the technical field of pressure testing machines, in particular to an electro-hydraulic pressure testing machine. Background Art

[0002] The electro-hydraulic pressure testing machine is a mechanical device mainly used for compression testing of various materials. The machine uses a hydraulic system to apply the test force. The test data is measured by an oil pressure sensor and displayed on a digital tube. It has functions such as peak hold and loading speed display. The operation and display parts are at an appropriate height to facilitate the operator to operate and observe.

[0003] During use, the existing pressure testing machine can perform pressure tests on required materials, but it is unable to clean the table after the pressure test, resulting in a large amount of debris remaining on the table after multiple tests, which requires the staff to spend a lot of time cleaning. At the same time, it is also unable to fix the placed materials, resulting in the materials being squeezed off the top of the placement table during the test, thereby requiring the test to be repeated, which reduces the cleaning effect and fixation of the traditional electro-hydraulic pressure testing machine. For this reason, an electro-hydraulic pressure testing machine has been introduced. Utility Model Content

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. When the material is placed on the top of the electro-hydraulic pressure testing machine, the weight of the material itself applies pressure to the limit column, so that the limit column drives the placement plate and the connecting rod and the inner wall of the placement groove to move downward, and at the same time drives the moving plate to apply pressure to the spring. The moving plate moves downward, so that the fixed block drives the steel bar to move downward. At the same time, the steel bar moves downward and drives the clamping block to move, so that the clamping block clamps and fixes the material. At the same time, when the material is taken off the placement table after the test, the elastic potential energy of the spring is released, so that the protective plate returns to its initial state without working.

[0013] 2. The electro-hydraulic pressure testing machine rotates the rotating block 1 and the rotating block 2 on the outer wall of the rotating shaft so that the semicircular collecting block 2 and the semicircular collecting block 1 can rotate. At the same time, the clamping block clamps the clamping groove and places it on the top of the placement table to collect the debris generated during the experiment. After the test, the staff pushes the telescopic plate to move the telescopic plate on the inner wall of the moving groove, thereby preventing the debris from falling into the inner wall of the clamping component. At the same time, after the test, the control cabinet sends a signal to make the electric telescopic rod retract when receiving the signal, thereby driving the push block to scrape the debris on the top of the placement table into the inner walls of the semicircular collecting block 1 and the semicircular collecting block 2, thereby collecting the debris remaining during the experiment and reducing the cleaning time of the staff.

By moving the movable plate 902 downward, the fixed block 903 drives the steel bar 904 to move downward. At the same time, the steel bar 904 moves downward and drives the clamping block 905 to move, so that the clamping block 905 clamps and fixes the material, thereby fixing the material and collecting the debris generated by the inner wall of the pressure testing machine body 2.
