Description

Technical Field

[0001] The present invention relates to the field of detection technology, and in particular to a detection device for a vacuum simulation chamber and a use method thereof. Background Art

[0002] The vacuum simulation chamber is a device for testing spacecraft. Its environmental conditions are a vacuum degree better than 6.5×10-3Pa, a cold black background, and a hemispherical normal emissivity greater than 0.90. During the simulation test, the test pieces are mostly in a working state and their working parameters and environmental parameters are measured to simulate the space environment and verify whether the parts meet the standards. Due to the different pressures inside and outside, the vacuum simulation chamber may be squeezed and concave by the pressure in the later stage. A real damage detector is needed to detect the squeezed damaged position.

[0003] When it is necessary to conduct extrusion damage detection on the vacuum simulation chamber, since there is no tool to automatically explore the vacuum chamber, the staff is required to use a real damage detector to detect it bit by bit. This is not only very cumbersome but also a waste of time and efficiency, which wastes manpower and increases the workload of the staff. Summary of the invention

[0010] Preferably, slideways are symmetrically arranged on both sides of the second plate body, and slide rails matching the slideways are arranged on one side of the two connecting plates.

[0011] By adopting the above scheme, by setting slideways on both sides of the plate body 2 and a slide rail on one side of the connecting plate, when adjusting the height of the plate body 1, the slide rail on the connecting plate can slide in the slideway, thereby avoiding the possibility of tilting of the plate body 1 when adjusting the height and increasing the strength of the plate body 1 during operation.

[0012] Preferably, a rubber pad is provided at one end of the second screw rod.

[0013] By adopting the above scheme, a rubber pad is provided at one end of the screw rod 2, so that the fixing effect of the plate body 1 can be enhanced by increasing the friction force, thereby preventing the fixed plate body 1 from shaking during operation, which will cause the frame 1 extending into the vacuum chamber to shake, resulting in a collision with the inner wall of the vacuum chamber, causing damage to the true damage detector and the inner wall of the vacuum chamber.

[0014] Preferably, a protection component is arranged on the top of the support plate, and the protection component comprises a box body. A box body is arranged on the top of the support plate, and one end of the screw rod passes through one side of the box body.

[0015] By adopting the above solution, a box is arranged on the top of the support plate, so that the AC motor can be protected and the AC motor can be prevented from being exposed to the outside, so that the AC motor is not damaged by dust and impurities, which affects the service life of the AC motor.

[0021] Compared with the prior art, the present invention provides a vacuum simulation chamber detection device and a method of using the same, which have the following beneficial effects:

[0022] The detection device for a vacuum simulation chamber and the method for using the same are as follows: when in use, the entire detection assembly is moved to the chamber opening position of the vacuum chamber through the base, and then the frame 2 installed at the bottom of the connecting rod is lifted up using the electric telescopic rod to prevent the frame 2 from colliding with the vacuum chamber when the frame 1 is placed in the vacuum chamber. When the frame 1 is placed in the vacuum chamber, the electric telescopic rod is controlled to lower the frame 2, and then the AC motor on the top of the support plate is started, so that the AC motor drives the gear 1 to rotate, the gear 1 drives the gear 2 to rotate, and the gear 2 drives the screw rod 1 on its inner wall to rotate. Since the screw rod 1 passes through the threaded groove set on one side of the plate body, the rod body set at the bottom of the support plate passes through the through groove set on one side of the plate body. In this way, when the AC motor rotates, the screw rod 1 can drive the frame 1 set at one end thereof to move together, and rotate together with the screw rod 1, and detect the inner wall of the vacuum chamber through multiple true damage detectors on the outer wall of the frame 1. When the waveform on the inner side of the vacuum chamber exceeds the scrap judgment line, the true damage detector will alarm, thus achieving the function of automatic detection, avoiding the need for staff to perform detection, and saving manpower. Since the telescopic rod is set on the top of the shell on the support plate, when the frame 1 is moving for detection, it can also drive the frame 2 to perform mobile detection, so that the frame 2 can detect the top of the vacuum chamber that is not easy for the staff to operate, so that the inside and outside of the vacuum chamber can be detected at the same time, saving time.
