Figures 1 to 4 An oil splash prevention device for a test bench of the present application is described as follows.

[0048] like Figure 1 As shown, the present application provides a detection device for a proportional solenoid valve, including: a power source 1, a pressure sensor 4, a test rod 3 and a connector 5; the power source 1 installed on the test bench drives the test rod 3, a connector 8 is sleeved on the test rod 3, and the connector 8 is slidably installed on the test bench; the connector 5 used to match the solenoid valve is detachably installed on the end of the test rod 3 away from the power source 1; the pressure sensor 4 is installed in the test rod 3 to measure the pressure transmitted at the end where the connector 5 is located. It should be noted that in this example, the pressure sensor 4 is electrically connected to the power supply, and also includes a display screen for displaying the pressure sensor 4 so that the pressure value can be read in real time.

[0049] During actual use, firstly, the connector 5 is inserted into the internal grinding detection position of the electromagnetic valve to be tested, and the test rod 3 is driven by the power source 1 to move axially. The connector 5 on the test rod 3 continuously squeezes the detection position in the proportional electromagnetic valve, and the pressure sensor displays the pressure value between the connector 5 and the proportional electromagnetic valve on the display screen, so that the operator can judge whether the proportional electromagnetic valve is qualified according to the displayed pressure value. The present application has a simple structure and is easy to operate. The proportional electromagnetic valve is judged whether it is qualified by the value obtained by the pressure sensor 4, and the normal use of the proportional electromagnetic valve is ensured. Among them, the replaceable connector 5 is used to detect proportional electromagnetic valves of different specifications, which increases the application scope of the present application.

[0050] like Figure 1 , Figure 3 and Figure 4 As shown, in a specific example provided by the present application, the power source 1 includes a motor 11 and a telescopic mechanism 12; the motor 11 is installed on the test bench; the telescopic mechanism 12 is installed on the test bench, one end of the telescopic mechanism 12 is connected to the output shaft 111 of the motor 11, and the other end is connected to the test rod 3. Specifically, the telescopic mechanism 12 includes a base plate 121, a screw rod 122, a slider 125, and a guide rod 126; a mounting plate 123 is respectively provided in the length direction of the base plate 121, and the two mounting plates 123 are arranged parallel to the base plate 121; the two ends of the screw rod 122 are respectively installed on the connecting plate 127 through a bearing 129; the two ends of the guide rod 126 are respectively connected to a connecting plate 127, and the axis of the guide rod 126 is arranged parallel to the axis of the screw rod 122 in the same plane; the slider 125 is sleeved on the screw rod 122, and the slider 125 is threadedly connected to the screw rod 122, and the slider 125 is slidably sleeved on the guide rod 126.

[0051] During actual use, the motor 11 rotates, and the output shaft 111 of the motor 11 drives the screw 122 to rotate. The screw 122 rotates to move the slider 125. The guide rod 126 is used to ensure that the slider 125 moves stably. The slider 125 moves in the axial direction of the screw 122, and the test rod 3 is pushed to move axially through the connecting rod. When the connector 5 abuts the test position in the proportional solenoid valve, the slider 125 can continue to provide thrust for the test rod 3 to ensure the detection of the proportional solenoid valve. It should be noted that in other embodiments, the power source 1 can be an electric telescopic cylinder or a gear rack structure, which is not limited here.

In this embodiment, the protective cover 128 can protect the screw rod 122 structure to prevent structural damage caused by external impact. Specifically, one end of the moving rod 124 passes through the protective cover 128 for connecting the test rod 3.

Specifically, the mounting seat 6 is located between the moving rod 124 and the test rod 3.

The cooperation between the sliding block 81 and the slide groove is used to ensure that the test rod 3 maintains coaxiality during the movement of the test rod 3, and further ensure the accuracy of the data measured by the pressure sensor 4.

[0056] like Figure 2As shown, in a specific example provided by the present application, a harness hole 71 is provided on the connection seat 7 for connecting the wires of the pressure sensor 4 through. Furthermore, in this embodiment, a harness buckle is provided on the protective cover 128 for storing the wires connected to the pressure sensor 4. It is worth mentioning that the present application also includes a display installed on the outside of the protective cover 128 for displaying the value detected by the pressure sensor 4, which is used to judge whether the solenoid valve is qualified.

[0057] In a specific example provided in the present application, the connector 5 and the test rod 3 are connected by threads. In actual use, solenoid valves of different shapes and sizes can be replaced according to the specifications of the solenoid valves tested in Russia to improve the scope of application of the present application.
