Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0037] This embodiment provides a dual-purpose testing device, see reference. Figures 1-5 As shown, it includes: two support columns 1 and a crossbeam 2, wherein the crossbeam 2 is fixedly disposed between the two support columns 1;

[0038] The upper end of the crossbeam 2 is provided with a first motor 3, and the first motor 3 is connected to the threaded rod 31 in a transmission connection.

[0039] A movable part 4 is sleeved on the crossbeam 2. A push block 41 is fixedly provided on the movable part 4. The push block 41 is provided with a threaded hole that cooperates with the threaded rod 31. The threaded rod 31 passes through the threaded hole, so that the first motor 3 can drive the movable part 4 to move along the length direction of the crossbeam 2 by driving the threaded rod 31 to rotate.

[0040] The side wall of the movable part 4 is equipped with a telescopic rod 42, and the telescopic end of the telescopic rod 42 is connected to a movable plate 43. The telescopic rod 42 is used to drive the movable plate 43 to perform lifting and lowering movements.

[0041] A temperature chamber 5 is placed on the movable plate 43. A first vibration table 61 and a second vibration table 62 are arranged on both sides of the movable plate 43. The first vibration table 61 and the second vibration table 62 are independently arranged below the moving path of the movable plate 43.

[0042] In the above embodiment, a crossbeam 2 is provided between the two support columns 1. A first motor 3 is mounted on the crossbeam 2 and is connected to a threaded rod 31. A moving part 4 is slidably sleeved on the crossbeam 2 and moves along the direction of the crossbeam 2. A push block 41 is provided at the upper end of the moving part 4, and a through threaded hole is provided on the push block 41. The threaded rod 31 passes through the threaded hole and engages with the threaded hole. That is, the first motor 3 drives the threaded rod 31 to rotate, and the threaded rod 31 rotates in the threaded hole of the push block 41 to drive the movement. The moving part 4 moves along the direction of the crossbeam 2. A telescopic rod 42 is provided on the side of the moving part 4, and a movable plate 43 is installed at the telescopic end of the telescopic rod 42. The telescopic rod 42 is used to drive the movable plate 43 to move up and down. A temperature chamber 5 is placed on the movable plate 43, and a first vibration table 61 and a second vibration table 62 are placed at both ends of the movable plate 43. The first motor 3 drives the threaded rod 31 to rotate, which in turn drives the push block 41 at the upper end of the moving part 4 to move, thereby moving the moving part 4 along the direction of the crossbeam 2. For example, the moving part 4 moves along the direction of the movable plate 4. 3. Move the temperature chamber 5 above the first vibration table 61 and then extend the telescopic rod 42 to place the temperature chamber 5 on the first vibration table 61. After vibration testing on the first vibration table 61, lift the temperature chamber 5 away from the first vibration table 61 by moving the movable plate 43 upward. Drive the movable plate 43 to move above the second vibration table 62 by rotating the threaded rod 31. Control the movable plate 43 to move downward by controlling the telescopic rod 42 to place the temperature chamber 5 on the second vibration table 62. On the one hand, the temperature chamber 5 performs temperature testing and vibration testing on the components, realizing the application testing effect of temperature and vibration of the components. On the other hand, by configuring the first vibration table 61 and the second vibration table 62 with different vibration frequencies, two independent vibration test positions are formed, allowing the components to experience two different vibration environments in sequence at the same temperature. This simulates the product experiencing different vibration environments in sequence at the same temperature in actual application, thereby improving the authenticity and accuracy of the test. The temperature chamber 5 can be an insulated box to keep the components in a set constant temperature environment during testing.

[0043] In one embodiment of this application, see reference Figure 1 As shown, the other end of the threaded rod 31 is connected to the output end of the second motor 32.

[0044] In the above embodiment, by controlling the first motor 3 and the second motor 32 to rotate synchronously and in the same direction to drive the threaded rod 31 to rotate, the driving load of a single motor is reduced. The synchronous drive at both ends can reduce the bending deformation of the threaded rod 31 due to its own weight and load, and ensure that the meshing accuracy of the threaded rod 31 with the threaded hole of the push block 41 is consistent throughout the entire length range, thereby making the operation of the moving part 4 more stable.

[0045] In one embodiment of this application, see [reference] Figure 3As shown, the inner top wall of the moving part 4 is in rolling contact with the upper end of the crossbeam 2 through the roller frame 7. The roller frame 7 is used to provide sliding support for the moving part 4 when it moves along the length direction of the crossbeam 2.

[0046] In the above embodiment, the moving part 4 is slidably supported by the roller frame 7, so that part of the weight of the moving part 4 is borne by the crossbeam 2 and moves by rolling friction, thereby reducing the load on the moving part 4 from the push block 41, reducing the transmission wear of the threaded rod 31, and improving the transmission accuracy.

[0047] In one embodiment of this application, see reference Figure 4 As shown, a lifting rod 431 is provided at one end of the movable plate 43, a first insert block 432 is provided on the lifting rod 431, and a first insertion hole 51 is provided at the bottom of the temperature box 5. When the temperature box 5 is placed on the lifting rod 431, the first insert block 432 is inserted into the first insertion hole 51 at the bottom of the temperature box 5 to fix the temperature box 5.

[0048] In the above embodiment, when the temperature box 5 is placed on the lifting rod 431, the first insert 432 is inserted into the first insertion hole 51 at the bottom of the temperature box 5. The insertion of the first insert 432 into the first insertion hole 51 limits the temperature box 5 so that it will not slide relative to the moving plate 43 when it moves horizontally, thereby improving the stability of the temperature box 5 when it moves with the moving plate 43.

[0049] In one embodiment of this application, see reference Figure 4 and Figure 5 As shown, the temperature chamber 5 has a second insertion hole 52 at the bottom, and the first vibration table 61 and the second vibration table 62 have a second insertion block 611 on their upper surfaces.

[0050] In the above embodiment, when the temperature box 5 is placed on the vibration table, the second insert 611 is inserted into the second insert hole 52 to limit the temperature box 5 on the vibration table and prevent the temperature box 5 from falling off the vibration table when it comes into contact with the vibration table. This is beneficial to improving the stability of the temperature box 5 on the vibration table. Optionally, to improve the stability of the temperature box 5 on the vibration table, the temperature box 5 can be temporarily fixed to the vibration table by locking devices such as rope straps or buckles.

[0051] In one embodiment of this application, see reference Figure 4 As shown, the outer walls of the first vibration table 61 and the second vibration table 62 are provided with hangers 8.

[0052] In the above embodiments, the hanger 8 (e.g., a lifting lug or ring welded thereon) allows the vibration table to be lifted and moved using equipment such as overhead cranes or forklifts, facilitating the initial installation layout of the vibration table equipment and subsequent maintenance and replacement work, and making it easy to adjust the preset position of the vibration table.

[0053] In one embodiment of this application, see reference Figure 1 As shown, the first motor 3 and the second motor 32 are provided with mounting brackets 9 at their bottom ends, and the motors are connected to the crossbeam 2 through the mounting brackets 9.

[0054] In the above embodiment, the mounting bracket 9 (e.g., a sturdy L-shaped piece or pad) provides a stable mounting base for the motor and is firmly connected to the crossbeam 2 by multiple bolts, which increases the stability of the motor installation and helps to improve the stability of the motor operation.

[0055] In actual use of this application: the test component is placed in the temperature chamber 5. The temperature chamber 5 has a built-in clamp and mounting plate for clamping, installing and fixing the test component. The start device and control system control the lifting mechanism to retract the telescopic rod 42, raising the movable plate 43 and the temperature chamber 5 to a sufficient height to avoid collision during lateral movement. The start motor drives the threaded rod 31 to rotate, causing the moving part 4 to slide along the crossbeam 2 until the temperature chamber 5 is directly above the first vibration table 61. The telescopic rod 42 extends, the temperature chamber 5 descends, and the bottom surface of the temperature chamber 5 is in contact with the table surface of the first vibration table 61. The temperature chamber 5 can be temporarily fixed to the vibration table by locking devices such as rope straps and buckles. The first vibration table 61 is started to conduct the first vibration test on the components in the temperature chamber 5. After the first test is completed, the lock on the temperature chamber 5 is released, the telescopic rod 42 retracts to lift the temperature chamber 5 away from the first vibration table 61, the motor drives the threaded rod 31 to rotate, and the moving part 4 moves the temperature chamber 5 directly above the second vibration table 62 through the movable plate 43. The telescopic end of the telescopic rod 42 extends to place the temperature chamber 5 on the second vibration table 62. To improve the stability of the test, the staff can use ropes to temporarily fix the temperature chamber 5 to the vibration table. The second vibration table 62 is then turned on to conduct the second vibration test. The temperature chamber 5 can be an insulated box to keep the components in a set constant temperature environment during the test.

[0056] After the test is completed, the tested component is removed from the temperature chamber 5. The component is then observed for damage or tested to verify whether it can work properly. This process is designed to test the effect of different vibration environments on the component at a constant temperature.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
