Description

Technical Field

[0002] High and low temperature testing is an important means to evaluate the performance stability and reliability of products under different temperature environments. Currently, the commonly used high and low temperature testing devices are independent of each other, that is, they can perform low temperature detection and high temperature detection separately;

[0003] In actual detection use, the high and low temperature detection of products should also include cyclic detection, that is, continuously switching between high temperature and low temperature environments to test the performance quality of products. The current conversion method is to take out the test sample from the high temperature testing device and then put it into the low temperature testing device. Such operation will have a certain transfer time, resulting in a smaller temperature difference of the product and affecting the actual detection result and the detection quality. And during the detection process, it is often necessary to take out the detection product for observation at different time stages. In the existing test process, the product cannot be taken out without opening the testing device, which often interrupts the detection process, and the internal temperature gas will overflow when opened, affecting the temperature during the experiment. Based on this, a product performance detection device under high and low temperature environments is proposed. Summary of the Invention

Specific implementation manner

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Example, refer to Figures 1-8 , a product performance detection device under high and low temperature environments, including a detection tank body 1 equipped with a refrigeration device and a heating device, and air flow agitation components for controlling the flow of air are arranged at both the upper and lower ends of the detection tank body 1;

[0030] Among them, the refrigeration device and the heating device are prior arts, which are respectively arranged on both sides of the sealing fixing ring 2, and different temperature tests are carried out on both sides.

[0031] Furthermore, the air flow agitation component includes a sealing conversion piston 29 arranged inside the upper and lower ends of the detection tank body 1. A pneumatic cylinder 30 is arranged at one end of the detection tank body 1. The pneumatic cylinder 30 is a prior art and will not be elaborated here too much. It can achieve the effect of driving two sealing conversion pistons 29 to move synchronously. The output end of the pneumatic cylinder 30 is fixedly connected to the two sealing conversion pistons 29.

[0032] The advantage of adopting the above structure is that when the flipping motor 3 is used to drive the flipping test plate 4 to rotate, the gas between them will be connected. At this time, the output end of the pneumatic cylinder 30 can be synchronously controlled to drive the sealing conversion piston 29 to move, so as to ensure that the temperature gas rotating to one side flows to the gas on the side of the previous test chamber, avoid excessive loss of the temperature gas flipping to one side, and ensure the effect of quickly reaching the test temperature.

[0033] It is detected that a sealing and fixing ring 2 is fixedly arranged on the inner side wall of the tank body 1, and a sealing airbag is arranged on the inner wall of the sealing and fixing ring 2. The sealing airbag has flexibility and elasticity, and can ensure the sealing effect with the inner telescopic disc body 7;

[0034] A turning motor 3 is arranged on the detection tank body 1. The output end of the turning motor 3 penetrates through the side wall of the sealing and fixing ring 2 and extends outward, and is fixedly connected with a turning test disc 4. The other side of the turning test disc 4 is rotationally connected with the inner wall of the sealing and fixing ring 2 through a rotating shaft. The bottom of the turning test disc 4 is connected with a support seat 6 through a support frame 5, and the support seat 6 is connected with an inner telescopic disc body 7 through a telescopic connecting piece;

[0035] Furthermore, the telescopic connecting piece includes an electric push rod 18 arranged on the support seat 6. The output end of the electric push rod 18 is fixedly connected with an inner fixed disc 19. The outer side wall of the inner fixed disc 19 is rotationally connected with the inner telescopic disc body 7. The inner telescopic disc body 7 is in sliding contact with the turning test disc 4, and the sealing effect needs to be ensured at the sliding contact position;

[0036] The advantage of adopting the above further improvement is that during the turning process, through the setting of the electric push rod 18, the product to be detected on the inner telescopic disc body 7 can be retracted downward, avoiding the situation that the product to be detected touches the inner wall of the detection tank body 1 during the turning process.

[0037] Installation rail grooves 8 are opened on both the inner telescopic disc body 7 and the turning test disc 4. A detection conversion piece for fixing the product to be detected is detachably installed on the installation rail grooves 8. The detection conversion piece includes a conversion disc 10, and an elastic fixing piece is arranged on the conversion disc 10;

[0038] Furthermore, the elastic fixing piece includes a rectangular sliding groove opened on the conversion disc 10. The inner wall of the rectangular sliding groove is slidably connected with a clamping elastic block 20 through a guide post. The clamping elastic block 20 is connected with the inner wall of the rectangular sliding groove through a resisting spring sleeved on the guide post.

[0039] The bottom of the conversion disc 10 is fixedly connected with a driving rotating shaft 11. The bottom of the driving rotating shaft 11 is connected with the installation rail groove 8 through an installation rail block 12. The driving rotating shaft 11 rotates by itself through a self-driving piece, driving the product to be detected to rotate.

[0040] A switch door 9 is arranged on one side of the detection tank body 1. The switch door 9 can achieve the effect of installing and removing the product to be detected, and a sealing sampling device is arranged on the other side;

[0041] Furthermore, the sealing sampling device includes a sealing end cover 13 fixedly arranged on the inner side wall of the detection tank body 1. Arc-shaped sealing covers 14 are fixedly arranged at both ends of the sealing end cover 13. A control shaft 15 is rotatably arranged on the sealing end cover 13. A transfer seat 16 is fixedly connected to the outer side wall of the control shaft 15, and a four-leaf sealing plate 17 is fixedly arranged on the outer side wall of the control shaft 15.

[0042] It should be noted that adsorption magnets 26 are provided on the inner wall of the installation rail groove 8 on the inner telescopic disc body 7. The installation rail block 12 itself is magnetic and can adsorb with the adsorption magnets 26;

[0043] A transfer rail groove 27 adapted to the installation rail block 12 is provided on the transfer seat 16, and a horizontal push rod 28 for pushing the product to be inspected onto the transfer seat 16 is provided on the inner fixed disc 19.

[0044] With the above structure, when it is necessary to take out the product to be inspected in the test tank body 1 for inspection at different stages, the product to be inspected can be pushed into the transfer rail groove 27 on the transfer seat 16 by the horizontal push rod 28, and then the product to be inspected can be removed from the test tank body 1 by rotating the transfer seat 16, achieving the effect of inspecting the product to be inspected without affecting the normal internal test.

[0045] Furthermore, the self-driving member includes a driving motor 21 installed on one side of the support seat 6 through a connecting seat. The output end of the driving motor 21 is fixedly connected with a driving gear 22. A driving gear ring 23 meshing with the driving gear 22 is fixedly connected to the bottom of the flipping test disc 4. A fixed gear ring 24 is fixedly connected to the inner fixed disc 19, and a self-rotating gear 25 adapted to the fixed gear ring 24 is fixedly connected to the outer side wall of the driving rotating shaft 11.

[0046] It should be noted that both the driving gear 22 and the driving gear ring 23 are straight-tooth structures, and they can achieve the effect of meshing and transmission.

[0047] When the present invention is in use, the product to be inspected is installed on the conversion disc 10 through the clamping elastic block 20, and is sequentially docked with the installation rail groove 8 through the installation rail block 12 connected to the conversion disc 10. The product to be inspected is installed on the inner telescopic disc body 7 through the detection conversion member, and is fixed to the product to be inspected under the action of the adsorption magnet 26; at this time, according to the test requirements, the product to be inspected is subjected to high-temperature or low-temperature tests in the test tank body 1 through the refrigeration device or the heating device;

[0048] During the experiment, under the action of the driving motor 21, the driving gear 22 will be driven to rotate. Under the action of the driving gear ring 23 fixed on the flipping test disc 4, the inner telescopic disc body 7 will drive the product to be inspected to rotate around the axis of the inner telescopic disc body 7. Under the action of the self-rotating gear 25 and the fixed gear ring 24, the product to be inspected will be driven to rotate, so as to ensure that during the inspection process, the product to be inspected can uniformly change the temperature, ensure the temperature uniformity of the test, and ensure the test quality;

[0049] During this process, when it is necessary to take out the product to be inspected at different test time stages, the driving motor 21 can be controlled to stop at a predetermined position, and the horizontal push rod 28 provided thereon can be controlled to push. Under the action of the horizontal push rod 28, the product to be inspected on the conversion disk 10 can be moved from the installation rail groove 8 to the transfer rail groove 27, so as to move the product to be inspected onto the transfer seat 16. At this time, due to the action of the four-leaf sealing plate 17 and the arc-shaped sealing cover 14, it can be ensured that a large amount of gas will not escape during the transfer of the product to be inspected, and the product to be inspected can be taken out without opening the switch door 9, thus facilitating the progress of the test and ensuring the reliability of the temperature change during the whole test process;

[0050] During the test, when it is necessary to quickly change the temperature and generate a large temperature difference to test the stability of the product to be inspected, the product to be inspected can be flipped during the test, and the temperature conversion test can be quickly carried out without opening the detection tank body 1. Specifically, the electric push rod 18 is controlled in advance to contract the product to be inspected on the entire inner fixed disk 19 and the inner telescopic disk body 7 downward to reduce the height of the product to be inspected, and then the flipping motor 3 is controlled to rotate to drive the flipping test disk 4 to flip, so as to achieve the effect of quickly transferring the product to be inspected to different temperature test spaces, thereby avoiding the situation that the temperature difference decreases due to the transfer during the inspection of the product to be inspected.

[0051] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
