[0035] A second rubber block 9001 is provided on each first limiting plate 9 to enhance the sealing effect.

[0036] First, the staff installs the precision high-temperature test box at the location where it needs to be used. It should be noted that before conducting the experiment, the fixed block 4, the mounting plate 5, the limiting cylinder 6, the first electric push rod 7, the first limiting block 8, the first limiting plate 9, the connecting plate 10, the second limiting block 11 and the second limiting plate 12 are located in the normal temperature bin 1001, the two third limiting plates 14 are in contact with each other, the first limiting rod 15 is inserted into the corresponding avoidance groove, and the normal temperature bin 1001 and the high temperature bin 1002 are isolated. Then the staff opens the box door 2 below, and then controls the telescopic rod 4001 built into the fixed block 4 to retract, so that the mounting plate 5 loses its fixation. The limit of block 4 is achieved, and then the staff holds the limit cylinder 6 and rotates it. The limit cylinder 6 drives the parts connected to it to rotate, and drives the first electric push rod 7, the first limit block 8, the first limit plate 9, the connecting plate 10, the second limit block 11 and the second limit plate 12 to rotate. First, the limit cylinder 6 drives the mounting plate 5 to rotate with the rotating shaft at the connection on the fixed block 4 as the rotation center, so that the first limit block 8 rotates to face forward, and then the staff uses a tool to remove the first limit plate 9 from the first limit block 8, and then places the first cylindrical test material 001 in the first limit block 8, and then the staff uses a tool to remove the first limit plate 9 from the first limit block 8. The plate 9 is fixed on the first limiting block 8, that is, the end face of the cylindrical test material 001 is fixed by the first limiting block 8, the other end face of the cylindrical test material 001 is fixed by the first limiting plate 9, and the second rubber block 9001 is tightly fitted with the cylindrical test material 001, the first limiting block 8, the first limiting plate 9 and the cylindrical test material 001 are sealed to prevent the air in the chamber from entering the limiting cylinder 6 on the lower side of the cylindrical test material 001, and then the limiting cylinder 6 is rotated again to make the second limiting block 11 and the second limiting plate 12 face forward, and then the staff uses a tool to move the second limiting plate 12 is removed from the second limit block 11, and then the second cylindrical test material 001 is placed in the second limit block 11. Then the staff uses a tool to fix the second limit plate 12 on the second limit block 11, that is, the end face of the cylindrical test material 001 is fixed by the second limit block 11, and the other end face of the cylindrical test material 001 is fixed by the second limit plate 12. The second cylindrical test material 001 is fixed, and then the limit cylinder 6 is rotated again to keep the limit cylinder 6 in a vertical state, so that the first limit block 8 and the first limit plate 9 face upward, and the lower box door 2 is closed to prepare for testing.

[0037] Then, the telescopic rod 4001 built into the fixing block 4 is controlled to fix the mounting plate 5, and then the linear drive built into the detector 16 is controlled to run and drive the impact head 17 to move, and the impact head 17 on the detector 16 below pushes the cylindrical test material 001 fixed by the second limit block 11 and the second limit plate 12, and drives the limit cylinder 6, the connecting plate 10, the second limit block 11 and the second limit plate 12 to move upward, and the limit cylinder 6 drives the parts connected to it to move upward, and at the same time, the first electric push rod 7 is controlled to run and contract to drive the first limit block 8 and the first limit plate 9 to move downward, and then the detector 16 and the impact head 17 cooperate to further push, so that the upper end of the limit cylinder 6 fits The first electric push rod 7 is then controlled to push the first limit block 8 to move upward, and the first limit block 8, the first limit plate 9 and the cylindrical test material 001 cooperate with the first rubber block 8001 and the second rubber block 9001 to form a piston, and at the same time cooperate with the exhaust groove 6001 to discharge the air on the upper side of the cylindrical test material 001 in the limit tube 6, so that the first limit plate 9 contacts the third limit plate 14, and the exhaust groove 6001 is blocked by the outer wall of the first limit block 8 to prevent the air in the normal temperature chamber 1001 from being stored in the limit tube 6, and then the four second electric push rods 13 are controlled to contract to drive the two third limit plates 14 to move apart, and then the control The detector 16 and the impact head 17 further push the limit cylinder 6 and the connected parts upward, so that the fixing block 4 and the mounting plate 5 are in contact with the partition plate 1003, so that the cylindrical test material 001 above enters the high-temperature chamber 1002 from the normal temperature chamber 1001, so as to detect the temperature impact test of the cylindrical test material 001. In this process, the air in the normal temperature chamber 1001 is prevented from entering the high-temperature chamber 1002, and the air in the high-temperature chamber 1002 is prevented from entering the normal temperature chamber 1001. At the same time, the air in the normal temperature chamber 1001 and the high-temperature chamber 1002 are prevented from flowing through each other, which affects the temperature of the high-temperature chamber 1002 and its test effect. Then, the four second electric push rods 13 are controlled to push the two third electric push rods 13. The limit plates 14 move toward each other and approach the limit cylinder 6. At the same time, the third limit plate 14 drives the first limit rod 15 to enter the limit groove 6002 to fix the limit cylinder 6 to prevent the limit cylinder 6 from deflecting during the physical impact detection. Then the detector 16 is controlled to drive the impact head 17 to quickly impact the cylindrical test material 001 to perform a physical impact test. That is, the cylindrical test material 001 is subjected to a temperature shock test and a physical shock test respectively in the above manner, and the influence of the impact resistance of the cylindrical test material 001 at different temperatures is obtained. In addition, the above manner is used to avoid the cross-flow of hot and cold air in the normal temperature bin 1001 and the high temperature bin 1002, which affects the subsequent test results.

[0038] Example 2

[0039] On the basis of the above-mentioned embodiment 1, Figure 6-7As shown, the extrusion component includes a third electric push rod 101, a fourth limit plate 102, a second limit rod 103, an air inlet pipe 104 and an airbag 105; two third electric push rods 101 with a rectangular distribution are arranged on the left side of the detection box 1; another two third electric push rods 101 with a rectangular distribution are arranged on the right side of the detection box 1; the telescopic ends of the two third electric push rods 101 on the same side are fixedly connected with the fourth limit plate 102; each fourth limit plate 102 is fixedly connected with the second limit rod 103, and each fourth limit plate 102 is provided with an avoidance groove corresponding to the second limit rod 103; the second limit rod 103 is plugged into the limit groove 6002; four air inlet pipes 104 with a rectangular distribution are arranged on the detection box 1; the two air inlet pipes 104 on the same side are connected with the airbag 105.

[0040] Initially, the two fourth limit plates 102 are in contact with each other, and the second limit rod 103 is inserted into the corresponding avoidance groove to isolate the upper and lower sides of the fourth limit plate 102. First, the staff uses an external pump to connect with the air inlet pipe 104. After the cylindrical test material 001 is installed and fixed, the limit cylinder 6 is driven by the detector 16 and the impact head 17 to contact the two third limit plates 14. Then, the first electric push rod 7 is controlled to run to discharge the air in the upper part of the limit cylinder 6, and then the four second electric push rods 13 are controlled to retract. The two third limit plates 14 are driven to move apart, and then the detector 16 and the impact head 17 are controlled to further push the limit cylinder 6, so that the limit cylinder 6 contacts the lower surface of the two fourth limit plates 102. Then, the external pump is controlled to inject air into the airbag 105 through the air inlet pipe 104, so that the airbag 105 is wrapped tightly against the limit cylinder 6, squeezing the air in the cavity of the partition plate 1003, and at the same time isolating the normal temperature chamber 1001 and the high temperature chamber 1002. Then, the four third electric push rods 101 are controlled to contract and drive the fourth limit plate above. 102 move away from each other, and then control the detector 16 and the impact head 17 below to further push the limiting cylinder 6, that is, drive the first limiting block 8, the first limiting plate 9 and the cylindrical test material 001 into the high-temperature chamber 1002 through the limiting cylinder 6, and then control the four second electric push rods 13 to push the two third limiting plates 14 to move toward each other, and at the same time control the four third electric push rods 101 to push the two fourth limiting plates 102 to move toward each other, and at the same time drive the first limiting rod 15 and the second limiting rod 103 to enter the corresponding limiting groove 6002 , fix the limiting cylinder 6, and then control the detector 16 and the impact head 17 to perform a physical impact test, that is, the air in the normal temperature bin 1001 and the high temperature bin 1002 is isolated by the above-mentioned method. At the same time, when the third limiting plate 14 and the fourth limiting plate 102 are opened, the air in the normal temperature bin 1001 is prevented from entering the high temperature bin 1002 through the gap opened by the third limiting plate 14 and the fourth limiting plate 102, and the cross-flow of air in the normal temperature bin 1001 and the high temperature bin 1002 is further avoided, so as to realize efficient monitoring of the test temperature.

[0041] Example 3

[0042] Based on the above embodiment 2, Figure 3-4 As shown, each impact head 17 is covered with a rubber sleeve for sealing the first limiting plate 9 .

[0043] After the limiting cylinder 6 is fixed by the fourth limiting plate 102 and the second limiting rod 103, the linear drive inside the detector 16 is then controlled to drive the impact head 17 to perform a physical impact test on the cylindrical test material 001. After the physical impact test, the impact head 17 remains in its original state, that is, the rubber sleeve on the impact head 17 is tightly fitted with the first limiting plate 9 and the second limiting plate 12. When the cylindrical test material 001 is damaged after the physical impact test, the high temperature chamber 1002 is prevented from being damaged. The hot air enters the limiting cylinder 6 through the damaged part of the cylindrical test material 001, that is, the rubber sleeve on the impact head 17 cooperates with the first limiting block 8 and the first limiting plate 9 to block the limiting cylinder 6, so as to prevent the hot air from entering the limiting cylinder 6 after the cylindrical test material 001 is damaged. Then, the second electric push rod 13 and the third electric push rod 101 are controlled to drive the third limiting plate 14 and the fourth limiting plate 102 to move apart, so that the limiting cylinder 6 loses its limit, and then the first limiting plate 9 and the cylindrical test material 001 are pushed by the impact head 17 above. The columnar test material 001 is synchronously retracted downward through the impact head 17 below, driving the limit cylinder 6 to move downward. First, the impact head 17 drives the first limit plate 9 to move to the middle of the partition plate 1003, and then controls the operation of the external gas injection device, wraps the upper part of the limit cylinder 6 and the impact head 17 through the air bag 105, and then controls the impact head 17 to further push the limit cylinder 6 to move downward, so that the limit cylinder 6 moves completely into the normal temperature chamber 1001, and then controls the upper detector 16 to drive the impact head 1 7 is retracted upward, and when the impact head 17 passes the third limit plate 14 upward, the third limit plate 14 is controlled to move toward each other and close, and when the impact head 17 passes the fourth limit plate 102 upward, the fourth limit plate 102 is controlled to move toward each other and close, until the impact head 17 is completely reset. The detection is completed in the above manner, and at the same time, it is avoided that the hot air enters the limit tube 6 due to the damage of the cylindrical test material 001, resulting in the loss of hot air in the high-temperature chamber 1002, further improving the efficient monitoring effect of the temperature in the test chamber.
