[0002] With the development of the times, hydraulic laboratories are now equipped with a hydraulic cylinder test bench. The hydraulic cylinder is mainly a pressure finishing process, which utilizes the cold plasticity of metal at room temperature and uses a rolling tool to apply a certain pressure to the workpiece surface, causing the surface metal of the workpiece to produce plastic flow and fill in the original remaining concave troughs, thereby reducing the surface roughness of the workpiece.

[0003] Most traditional hydraulic cylinder test benches conduct hydraulic experiments on the surface of the test bench, and most of these hydraulic experiments are not equipped with protective devices, which can easily cause the internal hydraulic oil to splash outward when an accident occurs during the experiment, dirtying the test bench and the clothes of the experimenter. At the same time, hydraulic oil leakage accidents often occur when the hydraulic cylinder is subjected to extreme tests, which can easily cause the table surface to be contaminated with hydraulic oil after the leakage, making it difficult to clean. Utility Model Content

The top of the oil cylinder test bench body 1 is fixedly connected with a fixed block 4, and a shielding cover 5 is movably connected to the surface of the fixed block 4. An electromagnet 8 is fixedly installed inside the fixed block 4. A sliding groove 6 is opened inside the fixed block 4, and a sliding block 7 is movably connected inside the sliding groove 6. The bottom end of the sliding block 7 is fixedly connected with a sliding rod 9, and a spring 10 is movably sleeved on the surface of the sliding rod 9. The bottom end of the sliding rod 9 is fixedly connected with a moving plate 11, and the top of the moving plate 11 is fixedly connected with a second magnet 12.

[0021] See also Figure 2 The width of the push plate 16 is the same as the width of the drain trough 15 , and the push plate 16 is inserted inside the drain trough 15 .

[0022] It should be noted that, by inserting the push plate 16 inside the drain trough 15 , the dust and dirt left at the bottom of the drain trough 15 can be pushed to the top of the drain outlet 14 during the movement of the push plate 16 , so as to facilitate cleaning of the dirt inside the drain trough 15 .

[0023] See also Figure 2 There are two groups of guide grooves 13, and the guide grooves 13 are inclined fifteen degrees toward the direction of the sewage trough 15.

[0024] It should be noted that the hydraulic oil remaining from above the grid plate 2 flows into the drain groove 15 through the guide groove 13 and is discharged through the drain port 14 inside the drain groove 15 .

[0025] See also Figure 2 The shielding cover 5 is installed just above the center of the grid plate 2 , and the shielding cover 5 is fixedly connected to the movable plate 11 .

[0026] It should be noted that, by installing the shielding cover 5 right above the middle of the two groups of hydraulic rods 3, the movable plate 11 can drive the shielding cover 5 to cover the middle of the two groups of hydraulic rods 3 during the movement, and the hydraulic oil splashes out.

[0027] Working principle: when it is needed to be used, the electromagnet 8 is energized to generate magnetic force, and the second magnet 12 is pushed downward by the action of the magnetic force. The second magnet 12 drives the moving plate 11 to move downward. In the process of moving downward, the moving plate 11 will pull the sliding rod 9 and the sliding block 7 downward. The sliding block 7 moves downward in the sliding groove 6 and squeezes the spring 10. The downward movement of the moving plate 11 will drive the outer shielding cover 5 to move downward, so that the shielding cover 5 is covered on the outer side of the middle of the two groups of hydraulic rods 3 in the middle of the grid plate 2. When shielding is not needed, the electromagnet 8 is powered off, and the second magnet 12 that loses the magnetic force will be squeezed upward by the elastic force of the moving plate 11 and the spring 10, so as to facilitate movement. The plate 11 drives the shielding cover 5 to move upward, making it safer during the experiment. When the hydraulic oil leaks during the experiment, it will drip on the surface of the grid plate 2, and fall into the guide groove 13 through the surface of the grid plate 2. The hydraulic oil in the guide groove 13 will flow into the drain groove 15 at an inclined angle. When there are a lot of impurities and dust inside the drain groove 15, turn on the servo motor 17 to drive the threaded rod 18 to rotate. The threaded rod 18 drives the moving rod 19 and the push plate 16 to move forward through the internal thread inside the moving rod 19, thereby pushing the push plate 16 to push the impurities and dust inside the drain groove 15 to the top of the drain port 14, which is convenient for cleaning the oil stains inside the drain groove 15.
