A display screen 6 is embedded in one side of the test chamber body 1, and operation buttons 7 are distributed on one side of the test chamber body 1. The heater 4 and cooler 5 are started by operating buttons 7, and then the heater 4 and cooler 5 heat and cool the inside of the test chamber body 1. The temperature inside the test chamber body 1 is then displayed on the display screen 6. A sealing cover 8 is sealed on the top outer wall of the test chamber body 1, and handles 9 are symmetrically welded on the top outer wall of the sealing cover 8. The sealing cover 8 is lifted by the handles 9 to facilitate the placement of the tested parts into the clamping plate 3010.

[0021] The hot and cold circulation assembly 2 includes a first motor 201, a first gear 202, a heat insulation plate 203, a rotating port 204, a rotating shaft 205, a rotating plate 206, a heat insulation rubber pad 207, a support plate 208, and a second gear 209. A heat insulation plate 203 is fixedly connected to the inner wall of the middle section of the test chamber body 1. A rotating port 204 is opened in the middle of the heat insulation plate 203. A rotating shaft 205 is rotatably connected to the rotating port 204 and the heat insulation plate 203. A rotating plate is fixedly connected to the rotating shaft 205. 206. Heat-insulating rubber pads 207 are fixedly connected to both sides of the rotating plate 206 corresponding to the position of the rotating opening 204. A support plate 208 is fixedly connected to one side of the outer wall of the heat-insulating rubber pad 207. A second gear 209 is installed on the outer wall of one end of the rotating shaft 205. A first gear 202 is meshed on the outer wall of the top end of the second gear 209. A first motor 201 is embedded in one side of the test chamber body 1, and one end of the output shaft of the first motor 201 is fixedly connected to the outer wall of the first gear 202.

[0022] Working principle: When the parts are clamped, the sealing cover plate 8 seals the test chamber body 1. The heater 4 and the cooler 5 are started to heat and cool the inside of the test chamber body 1. Then, the hot and cold environments are separated by the heat insulation plate 203. The parts are subjected to cold and hot tests in the cold and hot environments, thus conducting extreme tests on the parts. After the parts have been tested in the cold or hot environment, the first motor 201 is started to rotate the first gear 202. Then, under the action of the second gear 209, the rotating plate 206 on the rotating shaft 205 rotates 180 degrees with the heat insulation rubber pad 207. The support plate 208 drives the mounting frame 301 to exchange, so that the two parts can be exchanged from the cold and hot environments. This ensures that the parts can be fully tested. The two parts can be automatically exchanged in the cold and hot environments without manual assistance, reducing the labor burden and improving the test results of the parts.

When the winding wheel 305 is reset, the clamping plate 3010 on the lifting rod 308 is reset along the lifting hole 302 under the action of the springs 309.

[0025] First, install the main body 1 of the test chamber onto the vibration test bench. Then, lift the sealing cover 8 using the handle 9, and place the tested parts onto the clamping plate 3010. At this time, start the second motor 304 to rotate the winding wheel 305, which winds up the connecting rope 306, causing the connecting rope 306 to rise and fall along the guide hole 303. Then, the lifting rod 308 on the lifting plate 307 rises and falls along the lifting hole 302 on the mounting frame 301, thereby clamping and fixing the parts with the clamping plate 3010. After the cold and heat test is completed, start the second motor 304 to reset the winding wheel 305. Then, under the action of the spring 309, the clamping plate 3010 on the lifting rod 308 resets along the lifting hole 302, and then the parts are taken out. The parts can be automatically clamped without the need for manual assistance, reducing the manual burden and improving the clamping effect.
