Description

Technical Field

[0001] The present invention relates to the technical field of environmental test equipment, and specifically relates to a new type of temperature, humidity and vibration three-in-one test chamber. Background Art

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

[0003] However, when large workpieces are tested, they need to be manually carried to the flexible connection device or the vibration table on the test chamber. Due to the large volume of the workpiece and the high position of the test station, the handling process is difficult, which not only consumes manpower, but also poses a safety hazard as it may fall during handling; at the same time, the high-humidity environment and frequent temperature changes inside the test chamber will cause water mist to easily condense on the surface of the observation window. When the operator observes the internal test situation through the observation window, the water mist will blur the line of sight, affecting the observation of the state change of the workpiece during the test, and thus interfering with the accurate acquisition of test data and the effective judgment of test results; after the large workpiece is carried to the test chamber, it needs to be fixed to the flexible connection device by bolts. However, due to the narrow internal space of the test chamber, the operating space for the operator during the fixing operation is small, resulting in low installation efficiency.

[0024] Specifically, such as Figure 8 , Figure 10 , Figure 11 , Figure 12 , Figure 14 and Figure 15As shown, a guide plate 604 is fixedly connected to the bottom of the fixed rod 504. The mounting plate 601 is slidably connected to the guide plate 604. A driving rod 606 is slidably connected within the fixed rod 504.

When the mounting seat 701 is installed onto the mounting plate 601, it abuts against the inclined surface of the limiting block 602, causing the limiting block 602 to retract into the mounting plate 601 and the second spring 603 to contract. When it slides to a certain position, the limiting block 602 is engaged with the mounting seat 701 under the action of the second spring 603, quickly fixing the mounting seat 701. A sliding plate 703 is fixedly connected to the sliding rod 702. The sliding plate 703 is slidably connected to the mounting seat 701. A fourth lead screw 704 is rotatably connected within the mounting seat 701. The sliding plate 703 is threadedly connected to the fourth lead screw 704. A connecting seat 711 is installed on the horizontal sliding table 11. Two fixing grooves 712 are provided on the connecting seat 711. A guide sleeve 707 is fixedly connected to the fixed rod 504. An adjusting plate 708 is slidably connected within the guide sleeve 707. A fourth driving member 710 is installed on the adjusting plate 708. A spline shaft 706 is installed at the driving end of the fourth driving member 710. A spline groove 705 is provided at the end of the fourth lead screw 704. The spline shaft 706 is inserted into the spline groove 705. By starting the fourth driving member 710 (the fourth driving member 710 is preferably a motor), the rotation of its output shaft drives the spline shaft 706 to rotate. The spline shaft 706 drives the fourth lead screw 704 to rotate through the spline groove 705. The fourth lead screw 704 threadedly drives the sliding plate 703 to slide. The sliding plate 703 will drive the sliding rod 702 to be tightened against the connecting seat 711, fixing the mounting seat 701 and the connecting seat 711.

At the same time, the adjusting plate 708 will adjust the position of the fourth driving member 710, causing the spline shaft 706 to disengage from the spline groove 705. The adjusting plate 708 is driven by the third driving member 709.

[0025] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, a flexible connection device 8 is installed at the bottom of the test box body 2. The protection structure 3 includes a guide rail 301 fixedly connected to the test box body 2 and a protection door 302 slidably connected to the guide rail 301. A connection frame 303 is slidably connected inside the protection door 302. A sealing ring 304 is fixedly connected to the connection frame 303. The sealing ring 304 is engaged with the test box body 2. A threaded ring 305 is fixedly connected to the guide rail 301. A first lead screw 306 is threadedly connected in the threaded ring 305. A jack 307 is provided on the protection door 302. The first lead screw 306 is inserted into the jack 307. Inserting the first lead screw 306 into the jack 307 facilitates fixing the protection door 302 and improves stability. A rotating block 308 is rotatably connected to the first lead screw 306. A connecting block 309 is fixedly connected to the rotating block 308. The connecting block 309 is slidably connected to the protection door 302. The connecting block 309 is fixedly connected to the connection frame 303. Through the threaded cooperation between the first lead screw 306 and the threaded ring 305, the end of the first lead screw 306 will move towards the jack 307 and be inserted into it. At the same time, the first lead screw 306 drives the rotating block 308 and the connecting block 309 to move. Since the connecting block 309 is fixedly connected to the connection frame 303, the connecting block 309 will also drive the connection frame 303 and the sealing ring 304 to move, so that the sealing ring 304 is engaged and pressed tightly with the sealing groove on the test box body 2, improving the sealing performance of the protection door 302. The water scraping structure 4 includes a mounting shaft 401 rotatably connected to the protection door 302 and a scraper 402 fixedly connected to the mounting shaft 401. The mounting shaft 401 drives the scraper 402 to rotate and scrape the water mist on the observation window 9 to avoid affecting the observation effect. A connecting rod 403 is fixedly connected to the mounting shaft 401. A fixed shaft 404 is fixedly connected to the connecting rod 403. A rotating sleeve 405 is rotatably connected to the fixed shaft 404. Two guide rods 407 are fixedly connected to the unit room 1.

The other end of the connecting pipe 414 is installed with an exhaust pipe 415. When the piston 410 moves downward, air enters the connecting pipe 414 through the second one-way valve 413 and is finally blown out through the exhaust holes of the exhaust pipe 415.The exhaust hole blows air towards the observation window 9 to make the water flow down better. The exhaust pipe 415 is provided with an exhaust hole.

[0026] When the present invention is in use, first slide the mounting bracket 501 along the mounting rod 513 of the vibration table 10. Before sliding, lower the mounting seat 701 to the lowest position. The mounting seat 701 will push against the limit plate 511 and move downward. At the same time, the first spring 512 contracts. When the mounting bracket 501 slides to a specified position on the mounting rod 513, control the mounting seat 701 to move upward a certain distance, so that the limit plate 511 is snapped into the mounting groove 514 at the bottom of the mounting rod 513 under the action of the first spring 512. By engaging the limit plate 511 with the mounting rod 513, it is convenient to fix the slid mounting bracket 501. At this time, since the workpiece is pre-mounted on the mounting seat 701 with bolts, and the mounting seat 701 is located between the two mounting plates 601, the second driving member 510 (the second driving member 510 is preferably a motor) can be directly started. Its output shaft rotates to drive the third lead screw 509 to rotate. The third lead screw 509 will thread-drive the guide block 508 to move upward. The guide block 508 drives the lifting rod 502 to move upward. The mounting seat 701 is driven to move upward through the fixing block 503 and the fixing rod 504. After the mounting seat 701 moves upward a certain distance, start the first driving member 506 (the first driving member 506 is preferably a motor). Its output shaft drives the second lead screw 505 to rotate. The second lead screw 505 thread-drives the fixing block 503 to slide towards 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 above the connecting seat 711, by lowering the mounting seat 701 a certain distance, the two cross bars at the bottom are inserted into the fixing grooves 712 on the connecting seat 711 to complete the workpiece handling. By the up and down movement of the lifting rod 502 in cooperation with the front and back movement of the fixing rod 504, it is convenient to handle larger workpieces, reduce the difficulty of handling large workpieces, and improve the safety during handling; After the mounting base 701 is located on the connecting base 711, the fourth driving member 710 (the fourth driving member 710 is preferably a motor) can be started, and its output shaft rotates to drive the spline shaft 706 to rotate. The spline shaft 706 drives the fourth lead screw 704 to rotate through the spline groove 705. The fourth lead screw 704 threadedly drives the slide plate 703 to slide, and the slide plate 703 drives the slide rod 702 to be tightened against the connecting base 711, so as to fix between the mounting base 701 and the connecting base 711. After the mounting base 701 is installed, the third driving member 709 (the third driving member 709 is preferably a hydraulic rod) is started, and its telescopic end contracts to drive the adjusting plate 708 to slide with the guide sleeve 707. At the same time, the adjusting plate 708 adjusts the position of the fourth driving member 710, so that the spline shaft 706 is disengaged from the spline groove 705. At the same time, the adjusting plate 708 drives the driving rod 606 to slide through the adjusting 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 groove 607, the driving groove 607 will not change the position of the driving shaft 605. When the spline shaft 706 is disengaged, the driving shaft 605 enters the inclined part of the driving groove 607. Continuing to slide the driving rod 606, the driving groove 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 no longer lies at the bottom of the mounting base 701. At this time, the fixing rod 504 can be lifted, and then the fixing rod 504 is moved away from the vibration table 10 through the second lead screw 505, driving the mounting plate 601 to move to a position where it does not affect the movement of the mounting base 701. At this time, the exciter on the vibration table 10 can be rotated 90 degrees through the driving member, and then connected to the horizontal slide table 11 through the connecting member. Starting the exciter to generate vibration, the horizontal slide table 11 reciprocates to test the workpiece. Since the mounting base 701 and the mounting plate 601 are detachable, it is convenient to install the workpiece in an open space, and then install the mounting base 701 with the workpiece installed thereon onto the mounting plate 601, increasing the operating space and improving the installation efficiency. When the mounting base 701 is installed on the mounting plate 601, it abuts against the inclined surface of the limiting block 602. The limiting block 602 contracts into the mounting plate 601, and the second spring 603 contracts. When sliding to a certain position, the limiting block 602 is engaged with the mounting base 701 under the action of the second spring 603, quickly fixing the mounting base 701. When performing temperature and humidity detection, the test chamber 2 and the flexible connection device 8 are moved above the horizontal slide table 11 through the unit room 1, and then the test chamber 2 is moved downward through the driving member on the unit room 1. When moving to a certain position, the connecting base 711 can be located on the flexible connection device 8, and then the bolt is passed through the mounting hole of the flexible connection device 8 to be installed with the horizontal slide table 11. Subsequently, only the mounting base 701 needs to be installed on the connecting base 711. When performing vertical vibration, the mounting frame 501 is moved to the designated position, and the limiting plate 511 is engaged with another mounting groove 514, so that the mounting frame 501 can be installed at another position. (During detection, the temperature and humidity control part adjusts the temperature inside the box through the refrigeration and heating modules, and controls the humidity by using the humidification and dehumidification devices,The sensor monitors and feeds back data to the controller in real time to form a closed-loop regulation to maintain the target temperature and humidity. The vibration system consists of components such as a vibration table 10 and an exciter. The controller drives the exciter to generate mechanical vibration according to the set vibration parameters (such as frequency, amplitude, waveform), which is transmitted to the test sample through the tabletop. The temperature and humidity environment and the vibration load in the test chamber 2 act on the sample simultaneously to simulate the complex working conditions of high temperature, low temperature, humidity, dryness, and vibration coupling that the product may encounter during actual transportation or use, for detecting the performance stability, structural strength, and environmental adaptability of the product); When closing the protective door 302, slide the protective door 302 along the guide rail 301. The setting of the guide rail 301 makes its sliding stable. After closing the protective door 302, through the threaded cooperation of the first lead screw 306 and the threaded ring 305, the end of the first lead screw 306 will move towards the jack 307 and be inserted into it. At the same time, the first lead screw 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 engaged and pressed tightly with the sealing groove on the test chamber 2, improving the sealing performance of the protective door 302. And it is convenient to fix the protective door 302 by inserting the first lead screw 306 into the jack 307, improving the stability. When it is necessary to observe the workpiece inside the test chamber 2 through the observation window 9, rotate the connecting rod 403 by 180 degrees by holding the rod 12 and the fixed shaft 404. The connecting rod 403 will drive the mounting shaft 401 to rotate, and the mounting shaft 401 will further drive the scraper 402 to rotate. The water mist on the observation window 9 is 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. The downward movement of the driving plate 406 drives the connecting rod 408 to move downward. The connecting rod 408 will drive the piston 410 to move downward. When the piston 410 moves downward, the tension spring 412 stretches. Since the bottom of the piston 410 forms a pressurizing chamber with the pressurizing tank 409, when the piston 410 moves downward, 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, making the water flow down better.
