It can efficiently evaluate the performance of products under extreme environments and dynamic working conditions, providing important basis for product quality improvement and optimization.

[0003] When using a high-precision, high-acceleration testing machine with dynamic testing capabilities, the heat generated by the internal equipment during operation is dissipated through a perforated plate. When maintenance is required, the perforated plate needs to be disassembled. However, traditional perforated plates are installed using multiple bolts and clips, making disassembly too cumbersome. Therefore, the market needs a new connection method to solve the current problems. Utility Model Content

[0004] The purpose of this utility model is to provide a high-precision, high-acceleration testing machine with dynamic testing capabilities. This addresses the problem in the background art where, during operation, the heat generated by the internal equipment is dissipated through a perforated plate. Furthermore, maintenance requires disassembling the perforated plate, which is traditionally installed using multiple bolts and clips, making disassembly cumbersome. Therefore, the market demands a new connection method to solve the current problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-precision, high-acceleration testing machine with dynamic testing capabilities, comprising a main body, a test chamber door installed at the front end of the main body, a groove provided at the lower position of the front end of the main body, a perforated plate installed at the lower position of the front end of the main body, the perforated plate engaging protrusions at both ends of the left and right ends within the groove, knobs provided at the left and right sides of the front end of the perforated plate, the knobs controlling the rotation of a first gear shaft at the lower end, the first gear shaft driving a second gear shaft fixed at the lower end to rotate, both the first and second gear shafts being sleeved within the perforated plate, and the second gear shaft being sleeved in a gear groove within the perforated plate, an upper insertion post and a lower insertion post being sleeved within the perforated plate, the left and right sides of the first gear shaft respectively fitting against the upper and lower insertion posts.

[0006] Preferably, a pressure gauge is provided at the upper position of the front end of the main body, and a high-leg base is fixed at the four corners of the lower end of the main body.

[0007] Preferably, a manual water inlet is provided at the upper front position of the right end of the main body, and a manual pressure relief valve is provided at the upper rear position of the right end of the main body.

[0008] Preferably, a pressure relief port, a water inlet, and a drain port are respectively provided at the lower rear end of the main body.

[0009] Preferably, the test chamber door is connected to the main body via a rotating hinge. After the test chamber door is opened, the pressure test chamber can be entered, and an air heater is installed inside the pressure test chamber.

[0010] Preferably, an insertion hole is provided at the lower inner wall of the front end of the main body. Multiple insertion holes are provided, which are used to connect with the upper insertion post and the lower insertion post respectively.

[0011] Preferably, the perforated plate has multiple heat dissipation holes at its front end, and the installation of the perforated plate with the main body allows the protrusion to engage with the inside of the groove.

[0012] Preferably, a gear structure is provided at the side end face of both the upper and lower insertion posts, and the gear structure of the upper and lower insertion posts is engaged with the first gear shaft. When the first gear shaft rotates, the upper and lower insertion posts move.

[0013] Compared with the prior art, this utility model provides a high-precision, high-acceleration testing machine with dynamic testing capabilities, which has the following advantages:

[0014] 1. When installing the perforated plate, insert the perforated plate into the opening at the lower front of the main body. During installation, the protrusion first engages with the inside of the groove, thus defining the position of the perforated plate. Turning the knob causes the first gear shaft to rotate. The first gear shaft, through the gear structure on the outer wall, drives the upper and lower insertion posts on both sides to move upward and downward respectively, so that the insertion posts are inserted into the inside of the insertion hole, thereby completing the installation of the perforated plate. This installation method allows for quick disassembly and installation without the need for tools.

[0015] 2. When the first gear shaft rotates, it drives the second gear shaft to rotate. The second gear shaft rotates inside the gear groove. Because the gear structure of the second gear shaft is engaged with the gear groove, an external force is required for the first gear shaft to rotate. After the external force is removed, it can maintain its position. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] The utility model provides, for example Figure 1-5 The high-precision, high-acceleration testing machine with dynamic testing is shown, including a main body 1. A test chamber door 3 is installed at the front end of the main body 1. A groove 8 is provided at the lower position of the front end of the main body 1. A mesh plate 4 is installed at the lower position of the front end of the main body 1. The mesh plate 4 engages the protrusions 7 at the left and right ends with the groove 8. A knob 5 is provided at the left and right sides of the front end of the mesh plate 4. The knob 5 controls the rotation of the first gear shaft 16 at the lower end. The first gear shaft 16 drives the rotation of the second gear shaft 17 fixed at the lower end. Both the first gear shaft 16 and the second gear shaft 17 are sleeved inside the mesh plate 4. The second gear shaft 17 is sleeved in the gear groove 18 located inside the mesh plate 4. An upper insertion post 11 and a lower insertion post 12 are sleeved inside the mesh plate 4. The left and right sides of the first gear shaft 16 are respectively attached to the upper insertion post 11 and the lower insertion post 12.

[0026] When using the equipment, first inject pure water into the steam tank through the manual water inlet 10, and at the same time observe the pressure gauge 2 to confirm that the system pressure is zero. Open the test chamber door 3, place the sample near the air heater inside the chamber, and ensure that the sample is connected to the BIAS voltage terminal before closing the door. Set dynamic parameters such as temperature and pressure through the controller. After starting, the air heater works with the steam system to regulate the temperature and humidity inside the chamber. Monitor the data of the pressure gauge 2 in real time during operation. If the pressure exceeds the specified value, the manual pressure relief valve 9 and the pressure relief port 13 will work together to release the pressure. After the test, wait for the pressure gauge 2 to return to zero and the temperature to drop below ℃, open the test chamber door 3 to take out the sample, and finally drain the condensate through the drain port 15. If the equipment is to be shut down for a long time, water needs to be injected through the water inlet 14 for drying operation to ensure that the residual water vapor inside the equipment is drained through the drain port 15.

[0027] like Figure 1 and Figure 3 As shown, a pressure gauge 2 is installed at the upper front end of the main body 1, and a high-leg base 6 is fixed at the four corners of the lower end of the main body 1. A manual water inlet 10 is installed at the upper front side of the right end of the main body 1, and a manual pressure relief valve 9 is installed at the upper rear side of the right end of the main body 1. A pressure relief port 13, a water inlet 14, and a drain port 15 are respectively installed at the lower rear end of the main body 1. The test chamber door 3 is connected to the main body 1 by a rotating hinge. After the test chamber door 3 is opened, the pressure test chamber can be entered, and an air heater is installed inside the pressure test chamber.

[0028] Pure water with a conductivity of 0.1 to 20 μS / cm is injected into the equipment through the manual water inlet 10. During water injection, the pressure gauge is observed to ensure the initial system pressure is 0 MPa. If the pressure exceeds 2.42 kg / cm² during operation... 2 Then the manual pressure relief valve 9 and the pressure relief port 13 work together to relieve pressure.

[0029] like Figure 4 and Figure 5 As shown, an insertion hole is provided on the inner wall of the lower front end of the main body 1. Multiple insertion holes are provided for connecting with the upper insertion post 11 and the lower insertion post 12 respectively. Multiple heat dissipation holes are distributed at the front end of the mesh plate 4. The installation of the mesh plate 4 and the main body 1 causes the protrusion 7 to be engaged in the inner position of the groove 8. Gear structures are provided on the side end faces of the upper insertion post 11 and the lower insertion post 12. The gear structures of the upper insertion post 11 and the lower insertion post 12 are engaged with the first gear shaft 16. When the first gear shaft 16 is rotated through the gear structure, the upper insertion post 11 and the lower insertion post 12 move.

[0030] When the first gear shaft 16 rotates, it drives the second gear shaft 17 to rotate. The second gear shaft 17 rotates inside the gear groove 18. Because the gear structure of the second gear shaft 17 is engaged with the gear groove 18, the first gear shaft 16 can only rotate with external force, and can remain in its position after the external force is removed.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
