Description

Technical Field

[0001] The utility model belongs to the technical field of aging test chambers, and in particular relates to an ozone aging test chamber. Background Art

[0002] As a very important industrial material, rubber has important applications in transmission, vibration isolation and other fields. However, due to the easy modification of its internal structure, its performance will decrease with the increase of usage time. Therefore, for rubber materials, it is very necessary to simulate the actual use conditions and predict the life of rubber product samples before entering large-scale industrial production. In the prior art, aging test chambers are used to carry out aging tests on rubber products. After searching, it was found that the application number "20202190384.X" discloses "a visual ozone aging device for thermally conductive silicone gaskets", which records "comprising a shell, an aging bin and a motor bin are arranged in the shell, the aging bin is arranged above the motor bin, and a turntable is arranged in the aging bin; a limit block is arranged at the top center of the turntable, and pull plates are arranged on both sides of the limit block, and the limit block and the An electric push rod is arranged between the pulling plates, a fixed plate is arranged on opposite sides of the two pulling plates, a slide plate is arranged above the fixed plate, a fixed block is arranged on opposite sides of the fixed plate and the slide plate, and a screw rod is inserted on the slide plate. When the above device is in use, the thermal conductive silicone gasket is stretched by stretching the electric push rod, thereby realizing the stretching effect test, and the anti-aging performance of the thermal conductive silicone gasket during the stretching process is tested by the introduced ozone. However, there are still certain shortcomings in the use of the above device: the above device can only test one rubber sample in a single test, and its test effect is low and it is not convenient to test samples of different lengths. When the rubber sample is stretched by the electric push rod, the rotation of the bottom turntable will affect the wiring of the electric push rod wire, thereby affecting the use of the device. Based on this, we propose a rubber aging test box that is more convenient to use. Utility Model Content

[0024] In this embodiment, the stretching assembly includes an electric push rod 13 fixedly installed on the top of the box body 1, the bottom end of the electric push rod 13 is fixedly connected to an adjusting mechanism 14, the bottom end of the adjusting mechanism 14 is installed with a top plate 15, and multiple groups of clamping assemblies are installed between the bottom plate 5 and the top plate 15, each group of clamping assemblies is composed of two clamping mechanisms 16, and the two clamping mechanisms 16 are respectively installed on the opposite surfaces of the top plate 15 and the bottom plate 5.

[0025] Specifically, the rubber sample can be clamped and fixed by the clamping mechanism 16, and the distance between the top plate 15 and the bottom plate 5 can be adjusted by the adjusting mechanism 14, so that rubber samples of different lengths can be clamped and fixed, and the rotating rod 4 is driven to rotate by the servo motor 3, so that the bottom plate 5 rotates, and the rubber sample can better react with ozone to improve the aging test effect, and the adjusting mechanism 14 is driven to rise and fall by the electric push rod 13, so that the rubber sample can be subjected to a tensile test.

[0026] In this embodiment, the clamping mechanism 16 includes a clamping block 161 installed on the top of the base plate 5 and the bottom of the top plate 15. A clamping groove 162 is provided on the surface of the clamping block 161, and a clamping plate 163 is provided in the clamping groove 162.

[0027] Specifically, by inserting the two ends of the rubber sample into the clamping grooves 162 respectively, and rotating the locking bolts 164 so that the clamping plate 163 clamps and fixes the rubber sample, it is more convenient to perform an aging test on the rubber sample.

[0028] In this embodiment, the adjustment mechanism 14 includes a sleeve 141 fixedly connected to the electric push rod 13, the bottom end of the sleeve 141 is sleeved with an adjustment rod 142, one end of the adjustment rod 142 is rotatably connected to the top of the top plate 15, and one side of the sleeve 141 is threadedly connected with a tightening bolt 143, and the end of the tightening bolt 143 is tightened against the surface of the adjustment rod 142.

[0029] Specifically, since the adjusting rod 142 is sleeve-connected with the sleeve 141, the extended length of the adjusting rod 142 is adjusted and then the tightening bolt 143 is tightened, so that the distance between the top plate 15 and the bottom plate 5 can be adjusted in this way. Since the adjusting rod 142 is rotatably connected to the top of the top plate 15, the top plate 15 drives the rubber sample to rotate without affecting the wiring of the electric push rod 13, which makes it more convenient for the staff to use the test box.

[0035] Specifically, the guide groove 167 cooperates with the guide block 168 to guide the moving direction of the clamping plate 163 .

[0036] In this embodiment, a controller 21 is installed on one side of the box body 1 , and the electric push rod 13 , the electric heating wire 10 , the ozone concentration sensor 11 , the temperature sensor 12 , the fan 9 and the servo motor 3 are all electrically connected to the controller 21 .

[0037] Specifically, the electrical equipment of the test box is controlled by the controller 21 .

[0038] Working principle: First, the distance between the top plate 15 and the bottom plate 5 is adjusted by the adjustment mechanism 14, so that it is suitable for aging tests of rubber samples of different lengths. Then, the rubber samples are clamped and fixed by multiple groups of clamping components. After the box door 6 is closed, ozone is generated by the ozone generator 8, and the ozone concentration is detected by the ozone concentration sensor 11. Heat is generated by the electric heating wire 10 and blows the heat to the rubber sample through the fan 9. The temperature can be detected by the temperature sensor 12. Since there are multiple groups of clamping components, aging tests can be performed on multiple rubber samples in a single test. The top plate 15 is driven to rise and fall by the electric push rod 13, so that the rubber sample can be tensile tested. When the servo motor 3 drives the bottom plate 5 to rotate, the top plate 15 is rotated with the action of the guide rod 18, and the adjusting rod 142 is rotatably connected to the top plate 15. The top plate 15 will not affect the wiring of the electric push rod 13 when rotating, so that the aging box is more convenient for the staff to use, and the transparent observation window 7 is provided to facilitate the staff to observe the progress of the rubber aging test.
