[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] A device for testing the performance of an aluminum honeycomb panel comprises a testing box 1, wherein a box door 2 is arranged at the front side of the testing box 1, a handle 3 is arranged on the box door 2, a rectangular sample holder 4 is arranged at the lower part of the testing box 1, at least one sample holder is arranged at the four inner sides of the sample holder 4, the middle part of one end of the sample holder 4 is connected to one end of a first rotating shaft 5 arranged horizontally, the other end of the first rotating shaft 5 passes through the testing box 1 and is fixedly connected to the output shaft of a motor 6 arranged outside the testing box 1, the motor 6 can increase its stability during use through a fixing rod, the first rotating shaft 5 is rotatably connected to the testing box 1 through a first bearing 7, the middle part of the other end of the sample holder 4 is connected to one end of a second rotating shaft 8 arranged horizontally, the second The other end of the rotating shaft 8 is rotatably connected to the detection box 1 through the second bearing 9. A first electric heating plate 10 is arranged on the lower side wall of the detection box 1. At least one first temperature sensor 35 is arranged on the lower side wall of the detection box 1. A vertical pipe 11 is arranged at the lower part of the detection box 1. Several atomizing nozzles 12 are arranged on one side of the vertical pipe 11. The middle part of the other side of the vertical pipe 11 is connected with the bottom of the salt spray solution storage 13 through a pipeline. A salt spray solution solenoid valve 14 and a salt spray solution pump 15 are arranged on the connecting pipeline between the vertical pipe 11 and the salt spray solution storage 13. A spacing structure is arranged in the detection box 1. The top center position of the detection box 1 is fixedly connected with the top end of the vertically arranged multi-stage hydraulic cylinder 16, and the bottom end of the multi-stage hydraulic cylinder 16 is provided with an impact head 17. When the present invention is used, the aluminum honeycomb panel sample is fixed in the sample fixing frame 4 through the sample fixing device, and then the box door 2 is closed, the first electric heating plate 10 is turned on to monitor the temperature in the detection box 1 in real time through the first temperature sensor 35. After the temperature rises to the specified temperature, the motor 6 is turned on to drive the first rotating shaft 5 and the sample fixing frame 4 to rotate, and at the same time, the salt spray solution solenoid valve 14 and the salt spray solution pump 15 are turned on to continuously pass the salt spray solution in the salt spray solution storage 13 into the detection box 1 through the atomizing nozzle 12. At the same time, the temperature is maintained to ensure the retention of the salt spray. When the aluminum honeycomb panel sample is at the specified temperature, the temperature of the sample is kept constant. After being in the temperature and salt spray environment for a specified time, it can be taken out for observation. At the same time, the sample fixing frame 4 can be rotated to a horizontal position to maintain the current position, and then the spacing structure is opened. The multi-stage hydraulic cylinder 16 drives the impact head 17 to perform an impact test on the aluminum honeycomb panel sample. At the same time, the operating pressure of the multi-stage hydraulic cylinder 16 is set by the pressure control device of the multi-stage hydraulic cylinder 16 to perform impact operations of different degrees. At the same time, only high-temperature operation can be performed and the impact test can be performed in a high-temperature environment after a specified time, so as to conveniently obtain a more accurate impact resistance performance of the aluminum honeycomb panel under extreme conditions.

[0022] Specifically, the sample holder described in this embodiment includes a "C"-shaped fixing block 18, which is fixedly connected to the inner side of the sample fixing frame 4. A screw hole 19 is provided at the top of the fixing block 18, and the screw hole 19 can be threadedly connected to a screw rod 20. When the present invention is in use, the edge of the aluminum honeycomb panel sample can be placed in the corresponding fixing block 18 and the edge of the aluminum honeycomb panel sample can be fixed by the screw rod 20.

[0023] Specifically, a pressing block 21 is provided at the bottom of the screw rod 20 described in this embodiment. Through the pressing block 21, the present invention can increase the contact area between the screw rod 20 and the aluminum honeycomb panel sample and enhance the fastening stability between the two.

[0024] More specifically, the spacing structure described in this embodiment includes two spacing plates 22. The two spacing plates 22 can divide the test chamber 1 into upper and lower spaces. The two spacing plates 22 are hingedly connected to the inner wall of the test chamber 1 on the side away from their adjacent sides. The top of the spacing plate 22 is hingedly connected to the bottom end of a first multi-stage electric push rod 23, and the top end of the first multi-stage electric push rod 23 is hingedly connected to the test chamber 1. Through the first multi-stage electric push rod 23, the present invention can conveniently drive the spacing plates 22 to open and close, so as to ensure that a closed space is formed in the lower part of the test chamber 1 during salt spray or high-temperature tests, thereby reducing the energy consumption for maintaining the temperature and the atomization environment, and also avoiding the influence of atomization and high temperature on the multi-stage hydraulic cylinder 16, so as to ensure the normal use of the present invention.

[0025] Even more specifically, a corrosion-resistant and high-temperature-resistant rubber protective layer 24 is provided on the outer periphery of the spacing plate 22 described in this embodiment. In the present invention, the rubber protective layer 24 can effectively protect the spacing plate 22, so as to ensure the long-term and stable use of the present invention.

[0026] To be more specific, since the impacted part of the aluminum honeycomb panel sample is suspended when the sample fixing frame 4 is rotated to a horizontal position to perform an impact test on the aluminum honeycomb panel sample, its single-sided impact resistance performance cannot be tested. In order to overcome the above problem, a fixed shell 25 with a top opening is arranged at the central position of the bottom of the detection box 1 described in this embodiment, and a horizontal support plate 26 is arranged on the top of the fixed shell 25. The support plate 26 can fit tightly with the opening of the fixed shell 25, and the four corners of the bottom of the support plate 26 are respectively fixedly connected to a vertically arranged second multi-stage electric push rod 27, and the bottom of the second multi-stage electric push rod 27 is fixedly connected to the bottom of the fixed shell 25. When performing an impact test, the second multi-stage electric push rod 27 of the present invention drives the support plate 26 to rise and contact the bottom surface of the aluminum honeycomb panel sample before performing the impact test, thereby ensuring the accuracy of the performance test results. At the same time, when not in use, the support plate 26 can be closely matched with the opening of the fixed shell 25 to avoid the second multi-stage electric push rod 27 being in a high temperature or salt spray environment for a long time to ensure its long-term stable use. At the same time, the fixed shell 25 is made of high temperature resistant and corrosion-resistant material, and a high temperature resistant and corrosion-resistant layer is arranged on the top surface of the support plate 26, so that it can be used for a long time in a high temperature and salt spray environment.

[0027] Furthermore, a high-pressure water nozzle 28 is respectively arranged on both sides of the lower part of the detection box 1 described in this embodiment, and the two high-pressure water nozzles 28 are respectively connected to the high-pressure water pipe 29 through pipelines, and the high-pressure water pipe 29 is provided with a high-pressure water pump 30 and a high-pressure water solenoid valve 31, and the bottom of the detection box 1 is connected to a drain pipe 32, and a drain pump 33 and a drain solenoid valve 34 are arranged on the drain pipe 32. After completing the test, the present invention cleans the aluminum honeycomb panel sample by opening the high-pressure water pump 30 and the high-pressure water solenoid valve 31 to allow water to pass through the high-pressure nozzle 28, thereby avoiding subsequent manual cleaning, and at the same time, the salt water accumulated when maintaining the salt mist environment can be regularly discharged through the drain pipe 32 by opening the drain pump 33 and the drain solenoid valve 34, which is convenient for use.

[0028] Furthermore, the salt spray solution storage device 13 described in this embodiment is provided with a second electric heating plate 36 at the bottom, an oscillator 37 is provided in the side wall of the salt spray solution storage device 13, a second temperature sensor 38 is provided on the side wall of the salt spray solution storage device 13, a liquid level sensor 39 is provided at the top of the salt spray solution storage device 13, and the top of the salt spray solution storage device 13 is connected with a funnel-shaped refilling tube 40, and a refilling valve 41 is provided on the refilling tube 40. The present invention can maintain the temperature of the salt spray solution through the second electric heating plate 36 and the second temperature sensor 38, and can prevent the precipitation of salts in the salt spray solution through the oscillator 37, and can monitor the liquid level in the salt spray solution storage device 13 in real time through the liquid level sensor 39. When the liquid level is lower than the specified liquid level, an alarm is issued to remind relevant personnel to quickly perform refilling operations through the refilling tube 40 to ensure that the salt spray continues.

[0029] Furthermore, the lower part of the detection box 1 described in this embodiment is connected to the exhaust pipe 42, and the exhaust pipe 42 is provided with an electronic pressure gauge 43 and an exhaust solenoid valve 44. In the present invention, the air pressure in the detection box 1 under the high-temperature atomization environment is monitored in real time by the electronic pressure gauge 43, and the exhaust solenoid valve 44 is opened when the pressure exceeds a specified value to avoid excessive air pressure in the detection box 1, thereby ensuring safe operation.

[0030] Furthermore, the top of the detection box 1 described in this embodiment is connected to the air inlet pipe 45, and the air inlet valve 46 is provided on the air inlet pipe 45. Since the liquid needs to be discharged after the detection is completed, the internal air pressure of the detection box 1 may be low after the final detection is completed, so that the box door 2 cannot be opened. In the present invention, the air inlet valve 46 is opened to make the air pressure inside and outside the detection box 1 consistent, thereby ensuring that the box door 2 can be opened stably.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
