Description

Technical Field

[0001] The invention relates to the technical field of environmental testing equipment, in particular to a novel temperature, humidity and vibration three-in-one testing box. Background Art

[0002] As a core equipment for simulating complex environmental conditions such as temperature changes, humidity fluctuations, and mechanical vibrations, the temperature, humidity, and vibration test chamber plays an important role in aerospace, electronics, and automobile manufacturing. It is mainly used to test the performance stability, reliability, and tolerance of products in comprehensive environments.

[0003] However, when testing large workpieces, they need to be manually transported to the soft connection device on the test chamber or the vibration table. Due to the large size of the workpiece and the high position of the test station, the transportation process is difficult, which not only consumes manpower but also poses a safety hazard if it falls during transportation. At the same time, the high humidity environment and frequent temperature changes in the test chamber will cause water mist to condense on the surface of the observation window. When the operator observes the internal test conditions through the observation window, the water mist will blur the line of sight, affecting the observation of the changes in the workpiece state during the test, and thus interfering with the accurate acquisition of test data and the effective judgment of the test results. After the large workpiece is transported to the test chamber, it needs to be fixed to the soft connection device with bolts. However, due to the small internal space of the test chamber, the operator has little operating space when performing fixing operations, resulting in low installation efficiency.

At the same time, the first screw rod 306 drives the rotating block 308 and the connecting block 309 to move. Since the connecting block 309 is fixedly connected to the connecting frame 303, the connecting block 309 will also drive the connecting frame 303 and the sealing ring 304 to move, so that the sealing ring 304 is tightly engaged with the sealing groove on the test box body 2, thereby improving the sealing performance of the protective door 302. The wiper structure 4 includes a rotatable connection to the protective door 30 2 and the scraper 402 fixedly connected to the mounting shaft 401.

The mounting shaft 401 is fixedly connected to a connecting rod 403, and the connecting rod 403 is fixedly connected to a fixed shaft 404. The fixed shaft 404 is rotatably connected with a rotating sleeve 405. Two guide rods 407 are fixedly connected to the protective door 302.

The exhaust pipe 415 is provided with an exhaust hole.

[0044] When the first spring 512 is engaged with the first spring 513, the first spring 512 is engaged with the second spring 513, and the first spring 513 is engaged with the second spring 511, so that the first spring 512 is engaged with the first spring 513. The guide block 508 moves up, and the guide block 508 drives the lifting rod 502 to move up, and drives the mounting seat 701 to move up through the fixing block 503 and the fixing rod 504. After the mounting seat 701 moves up a certain distance, the first driving member 506 (the first driving member 506 is preferably a motor) is started, and its output shaft drives the second screw rod 505 to rotate. The second screw rod 505 threadedly drives the fixing block 503 to slide toward the vibration table 10, driving the fixing rod 504 and the mounting seat 701 to move. At the same time, the guide shaft 507 guides the other fixing block 503. After the mounting seat 701 moves to the top of the connecting seat 711, the mounting seat 701 drops a certain distance, and the two cross bars at the bottom are plugged into the fixing grooves 712 on the connecting seat 711 to complete the workpiece transportation. The lifting rod 502 moves up and down to cooperate with the fixing rod 504 to move back and forth, which makes it easy to transport larger workpieces, reduces the difficulty of transporting large workpieces, and improves the safety during transportation.

[0045] After the mounting seat 701 is located on the connecting seat 711, the fourth driving member 710 can be started (the fourth driving member 710 is preferably a motor), and its output shaft rotates to drive the spline shaft 706 to rotate. The spline shaft 706 drives the fourth screw rod 704 to rotate through the spline groove 705, and the fourth screw rod 704 threadedly drives the slide plate 703 to slide. The slide plate 703 will drive the slide bar 702 to press against the connecting seat 711, thereby fixing the mounting seat 701 and the connecting seat 711. After the mounting seat 701 is installed, the third driving member 709 is started (the third driving member 709 is preferably a hydraulic rod), and its telescopic end contracts to drive the adjustment plate 708 and the guide sleeve 707 to slide. At the same time, the adjustment plate 708 will adjust the position of the fourth driving member 710 so that the spline shaft 706 and the spline groove 705 are aligned. The key slot 705 slips off, and at the same time, the adjustment plate 708 drives the driving rod 606 to slide through the adjustment rod 609, and the driving rod 606 slides with the fixed plate 608. At this time, since the driving shaft 605 is located in the vertical part of the driving slot 607, the driving slot 607 will not change the position of the driving shaft 605. When the spline shaft 706 slips off, the driving shaft 605 enters the inclined part of the driving slot 607 and continues to slide the driving rod 606. The driving slot 607 will drive the driving shaft 605 to drive the mounting plate 601 to slide along the guide plate 604, so that the "L"-shaped part at the bottom of the mounting plate 601 moves to no longer be located at the bottom of the mounting seat 701. At this time, the fixing rod 504 can be moved up, and then the fixing rod 504 is moved away from the vibration table 10 through the second screw rod 505, driving the mounting plate 601 The movement is such that it does not affect the movement of the mounting seat 701. At this time, the exciter on the vibration table 10 can be rotated ninety degrees by the driving member, and then connected to the horizontal slide 11 through the connecting member, the exciter is started to generate vibration, and the horizontal slide 11 slides back and forth to test the workpiece. The mounting seat 701 and the mounting plate 601 are detachable, which is convenient for installing the workpiece in an open area. The mounting seat 701 with the workpiece installed is then installed on the mounting plate 601, which increases the operating space and improves the installation efficiency. When the mounting seat 701 is installed on the mounting plate 601, it conflicts with the inclined surface of the limit block 602, and the limit block 602 shrinks into the mounting plate 601. The second spring 603 shrinks and slides to a certain position. The limit block 602 is engaged with the mounting seat 701 under the action of the second spring 603, and is quickly fixed. Fixed mounting seat 701, when performing temperature and humidity testing, the test box 2 and the soft connection device 8 are moved to the top of the horizontal slide 11 through the unit room 1, and then the test box 2 is moved downward by the driving member on the unit room 1. When it moves to a certain position, the connecting seat 711 can be placed on the soft connection device 8, and then the bolts are passed through the mounting holes of the soft connection device 8 and installed with the horizontal slide 11. Subsequently, it is only necessary to install the mounting seat 701 to the connecting seat 711. When performing vertical vibration, the mounting bracket 501 is moved to the specified position, and the limit plate 511 is engaged with another mounting groove 514, and the mounting bracket 501 can be installed in another position. (During the test, the temperature and humidity control part adjusts the temperature in the box through the cooling and heating modules, and controls the humidity using the humidification and dehumidification devices.The sensor monitors in real time and feeds data back to the controller, forming a closed-loop regulation to maintain the target temperature and humidity. The vibration system consists of a vibration table 10, an exciter, and other components. The controller drives the exciter to generate mechanical vibration according to the set vibration parameters (such as frequency, amplitude, and waveform). The vibration is transmitted to the sample under test through the table. The temperature and humidity environment in the test chamber 2 and the vibration load act synchronously on the sample, simulating the complex working conditions of high temperature, low temperature, humidity, dryness, and vibration coupling that the product may encounter during actual transportation or use. It is used to test the product's performance stability, structural strength, and environmental adaptability.

[0046] When the protective door 302 is closed, the protective door 302 is slid along the guide rail 301. The setting of the guide rail 301 makes it slide smoothly. After the protective door 302 is closed, the first screw rod 306 is threadedly engaged with the threaded ring 305, and the end of the first screw rod 306 moves toward the socket 307 and plugs into it. At the same time, the first screw rod 306 drives the rotating block 308 and the connecting block 309 to move. Since the connecting block 309 is fixedly connected to the connecting frame 303, the connecting block 309 also drives the connecting frame 303 and the sealing ring 304 to move, so that the sealing ring 304 is tightly engaged with the sealing groove on the test box body 2, thereby improving the sealing of the protective door 302. The first screw rod 306 is plugged into the socket 307 to facilitate fixing the protective door 302 and improve stability. When it is necessary to observe the workpiece inside the test box body 2 through the observation window 9, the grip rod 12 is connected to the fixed shaft 4 04 drives the connecting rod 403 to rotate one hundred and eighty degrees, and the connecting rod 403 will drive the installation shaft 401 to rotate, and the installation shaft 401 will then drive the scraper 402 to rotate, and the water mist on the observation window 9 will be scraped off by the rotation of the scraper 402 to avoid affecting the observation effect. At the same time, the fixed shaft 404 will drive the rotating sleeve 405 to roll in the through groove of the driving plate 406, so that the driving plate 406 slides on the guide rod 407, and the driving plate 406 moves downward to drive the connecting rod 408 to move downward, and the connecting rod 408 will drive the piston 410 to move downward. When the piston 410 moves downward, the tension spring 412 extends. Since the bottom of the piston 410 and the boost box 409 form a boost chamber, the piston 410 moves downward, and the air enters the connecting pipe 414 through the second one-way valve 413 and is finally blown out through the exhaust hole of the exhaust pipe 415. The exhaust hole blows air towards the observation window 9 to make the water flow better.
