Description

Technical Field

[0001] This invention relates to the field of testing technology for thin-walled aluminum profile frames, specifically to a pressure bearing capacity testing fixture for thin-walled aluminum profile frames. Background Technology

[0002] Thin-walled aluminum profile frames are widely used in many fields, such as building doors and windows, curtain walls, and protective fences and frame structures for industrial equipment, due to their lightweight, high strength, aesthetic appeal, and ease of processing and installation. For example, in large glass curtain walls of modern buildings, thin-walled aluminum profile frames, as key components supporting and fixing the glass, need to withstand a variety of complex external forces, including wind loads, their own weight, and possible accidental impacts. In industrial equipment protection, they must be able to withstand a certain degree of collision and vibration. These application scenarios place strict requirements on the pressure bearing capacity of thin-walled aluminum profile frames. Therefore, accurately testing their pressure bearing performance is a key link in ensuring safe and reliable use.

[0003] In light of the above, it should be noted that Chinese patent CN115326578A discloses a photovoltaic module aluminum frame strength testing device, which adaptively clamps and fixes frames of different sizes and performs multi-faceted compression testing on the frames through a testing plate. However, during actual testing, due to the influence of the aluminum profile frame body structure, the frame body is damaged by compression. Simple observation is not easy to detect the abnormality of the frame body in time. Therefore, continuous testing makes it impossible to detect the specific data of the frame body's pressure damage in time, resulting in uncertainty in the test results of the frame body.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a pressure bearing test fixture for thin-walled aluminum profile frames to solve the problems mentioned above.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pressure bearing test fixture for a thin-walled aluminum profile frame, comprising a test platform base, a lower support guide rail disposed inside the test platform base, clamping mechanisms symmetrically and slidably sleeved at both ends of the top of the lower support guide rail, a lower extrusion mechanism disposed between the clamping mechanisms, fixed end caps symmetrically disposed at both ends of the test platform base, the clamping mechanism comprising an outer movable base and a limiting extrusion plate, the lower extrusion mechanism comprising an inner movable base and an arc-shaped bracket, and a control panel disposed on the outer wall of the test platform base;

[0007] A movable end cover is provided on the top of the fixed end cover, and an observation cover is provided between the movable end covers. An upper support guide rail is provided on the inner wall of the observation cover. An upper extrusion mechanism is slidably sleeved on the surface of the upper support guide rail. The upper extrusion mechanism includes an upper movable base and an outer arc frame.

[0008] Furthermore, the test platform base is provided with an inner arc cover connected to the lower support guide rail. The inner arc cover has a liquid collection groove recessed on the inner walls on both sides near the lower support guide rail. The surface of the liquid collection groove is fitted with a test paper. A liquid storage tank is slidably sleeved on the bottom of one side of the test platform base.

[0009] Furthermore, the top of the external movable base is provided with a lifting cylinder frame connected to the limiting extrusion plate. A water inlet is provided in the middle of the end of the limiting extrusion plate facing the lower extrusion mechanism. A sealing soft plate is sleeved around the water inlet. A connecting hose is provided at the end of the limiting extrusion plate facing the fixed end cover. The connecting hose is connected to the outlet valve flange.

[0010] Furthermore, the top of the inner movable base is provided with an inner telescopic frame connected to the arc-shaped bracket, and an outer telescopic frame passing through the arc-shaped bracket is provided above the inner telescopic frame. The top of the outer telescopic frame is provided with a lower extrusion plate.

[0011] Furthermore, the inner walls on both sides of the arc-shaped bracket are recessed with sliding grooves, and a side moving base is slidably disposed on the surface of the sliding groove. A side telescopic frame facing the downward extrusion plate is disposed on the outer wall of the side moving base, and a side extrusion plate is disposed on the frame of the side telescopic frame.

[0012] Furthermore, the top of the fixed end cover is embedded with a lifting guide post that is sleeved with the movable end cover. The outer wall of the movable end cover away from the observation cover is provided with a lifting motor, and the lifting motor is connected to the lifting guide post. The inner wall of the fixed end cover facing the clamping mechanism is provided with a water outlet valve.

[0013] Furthermore, the observation cover is hinged to a movable cover plate on its side, and the upper support guide rail is fixedly installed at the center of the inner wall of the top of the observation cover. The upper support guide rail and the lower support guide rail are arranged symmetrically from top to bottom, and the lower support guide rail is fixed at the center of the inner wall of the bottom of the inner arc cover.

[0014] Furthermore, the top of the upper movable base is slidably sleeved with the upper support guide rail, the bottom of the upper movable base is provided with an inner telescopic frame two connected to the outer arc frame two, the center of the bottom frame of the outer arc frame two is provided with an outer telescopic frame two connected to the inner telescopic frame two, and the bottom of the outer telescopic frame two is provided with an upper extrusion plate.

[0015] Furthermore, high-definition recording sensors are installed on the inner walls of the adjacent connection between the test platform base and the observation cover. These sensors are used to collect the frame deformation reference values ​​generated by the thin-walled aluminum profile frame under test. A pressure sensor is installed inside the limiting extrusion plate. This sensor is used to collect the frame bearing pressure internal deformation values ​​generated by the thin-walled aluminum profile frame under test. An integrated sensor is installed on the inner wall at the bottom of the test platform base.

[0016] The beneficial effects of this invention are:

[0017] This invention uses a clamping mechanism and a lower extrusion mechanism to precisely clamp and initially limit the thin-walled aluminum profile frame within the test platform base, achieving stable clamping of the frame and ensuring the accuracy of its position during subsequent testing. This avoids positional deviations that could affect test results, thus providing precise clamping and positioning. The observation cover and movable cover are made of transparent acrylic material, allowing the testing process to be directly observed and facilitating real-time recording of the frame's shape changes under extrusion. The test paper in the collection tank visually displays the overflow of test water, quickly determining whether the frame is damaged. The multi-component collaborative operation allows for simultaneous extrusion testing of the bottom, sides, and top and bottom of the thin-walled aluminum profile frame in multiple areas.

[0018] This invention utilizes a testing and monitoring system with the collaborative action of multiple sensors to provide rich data for subsequent analysis. It can determine the pass / fail status of a test based on a comparison between the pressure bearing coefficient and a preset pressure bearing coefficient, and generate corresponding signals to feed back to the control panel. For different abnormal situations, it can generate signals of different levels and provide specific parameter information to help testers quickly locate problems. Data from each test is recorded and sent to a cloud database, achieving long-term data preservation and traceability. Parameters such as frame variation values, frame bearing values, and out-of-line values ​​pre-stored in the cloud database provide benchmarks and basis for subsequent comparative analysis.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figure 1 - Figure 10 As shown, this embodiment is a pressure bearing test fixture for a thin-walled aluminum profile frame, including a test platform base 1, a lower support guide rail 103 is provided inside the test platform base 1, clamping mechanisms 5 are symmetrically slidably sleeved at both ends of the top of the lower support guide rail 103, a lower extrusion mechanism 4 is provided between the clamping mechanisms 5, and fixed end caps 2 are symmetrically provided at both ends of the test platform base 1.

[0033] The clamping mechanism 5 includes an outer movable base 506 and a limiting extrusion plate 502. The lower extrusion mechanism 4 includes an inner movable base 404 and an arc-shaped bracket 402. After taking the thin-walled aluminum profile frame waiting to be tested, it is placed inside the test platform base 1. First, the lower extrusion mechanism 4 is started through the control panel. The inner telescopic bracket 401 drives the outer telescopic bracket 403 to slide upward synchronously until the lower extrusion plate 409 slides upward, lifting and limiting the thin-walled aluminum profile frame waiting to be installed inside the test platform base 1.

[0034] Then start the clamping mechanism 5, and the lifting cylinder frame 501 drives the limiting extrusion plate 502 to slide up until the limiting extrusion plate 502 is close to the preset position and aligned with the two ends of the thin-walled aluminum profile edge frame that has been initially limited, until the opening of the thin-walled aluminum profile frame covers the water inlet 505. The external moving base 506 drives the lifting cylinder frame 501 to move closer to each other and squeeze the thin-walled aluminum profile frame until it is limited and clamped between the two limiting extrusion plates 502. Close the movable cover plate 301 to complete the installation preparation before testing the thin-walled aluminum profile frame.

[0035] The test platform base 1 is equipped with an inner arc cover 101 connected to the lower support guide rail 103. The inner arc cover 101 is recessed on the inner walls on both sides near the lower support guide rail 103, and the surface of the liquid collection tank 102 is clamped with a test paper 7. A liquid storage tank 6 is slidably sleeved on the bottom of one side of the test platform base 1.

[0036] The top of the external movable base 506 is provided with a lifting cylinder frame 501 connected to the limiting extrusion plate 502. The middle of the end of the limiting extrusion plate 502 facing the lower extrusion mechanism 4 is provided with a water inlet 505. A sealing soft plate 504 is sleeved on the outer periphery of the water inlet 505. A connecting hose 503 is provided at the end of the limiting extrusion plate 502 facing the fixed end cover 2. The connecting hose 503 is connected to the flange of the water outlet valve 202.

[0037] The inner movable base 404 is provided with an inner telescopic frame 401 connected to the arc-shaped bracket 402 at the top. An outer telescopic frame 403 that penetrates the arc-shaped bracket 402 is provided above the inner telescopic frame 401. A lower extrusion plate 409 is provided at the top of the outer telescopic frame 403.

[0038] According to the test setup requirements, the inner movable base 404 and the upper movable base 801 move synchronously until they reach the area of ​​the thin-walled aluminum profile frame that needs to be pressure tested. The outer telescopic frame 403 drives the lower extrusion plate 409 to slide upward and contact the bottom outer wall of the thin-walled aluminum profile frame, and extrudes the bottom of it. The side movable base 406 slides along the inside of the sliding groove 405, and drives the side extrusion plate 408 to slide and adjust between the inner walls of the arc bracket 402 until it is flush with the outer walls on both sides of the thin-walled aluminum profile frame. The side telescopic frame 407 drives the side extrusion plates 408 to move closer to each other until they contact and extrude the outer walls on both sides of the thin-walled aluminum profile frame, and extrudes them.

[0039] The inner walls of both sides of the arc-shaped bracket 402 are recessed with sliding grooves 405. A side moving base 406 is slidably disposed on the surface of the sliding groove 405. A side telescopic frame 407 facing the downward pressing plate 409 is disposed on the outer wall of the side moving base 406. A side pressing plate 408 is disposed on the frame of the side telescopic frame 407.

[0040] Example 2: This example is a pressure bearing test fixture for a thin-walled aluminum profile frame, including a fixed end cover 2 with a movable end cover 204 on the top, an observation cover 3 between the movable end covers 204, an upper support guide rail 302 on the inner wall of the observation cover 3, and an upper extrusion mechanism 8 slidably sleeved on the surface of the upper support guide rail 302. The upper extrusion mechanism 8 includes an upper movable base 801 and an outer arc frame 802.

[0041] The top of the fixed end cover 2 is embedded with a lifting guide post 201 that is sleeved with the movable end cover 204. The outer wall of the movable end cover 204 away from the observation cover 3 is provided with a lifting motor 203, and the lifting motor 203 is connected to the lifting guide post 201. The inner wall of the fixed end cover 2 facing the clamping mechanism 5 is provided with a water outlet valve 202. The water pump is started through the control panel. The water pump is installed inside the fixed end cover 2 and is connected to the liquid storage tank 6 and the water outlet valve 202 through pipe fittings. It forms a water supply route with the connecting hose 503 and the water inlet 505.

[0042] The water pump draws test water through the water supply route and pours it into one end of the thin-walled aluminum profile frame until it is completely filled. The air inside the thin-walled aluminum profile frame is then guided to the storage tank 6 through the water supply route at the other end, so that the inside of the thin-walled aluminum profile frame is completely filled with test water, which constitutes the preparation for the test. It should be noted that the test water is pure water mixed with dye and fluorescent agent. After the thin-walled aluminum profile frame is damaged by the test compression, the test water overflows along the break and the break area is marked.

[0043] The observation cover 3 is hinged to a movable cover plate 301 on its side. The upper support guide rail 302 is fixedly installed in the center of the inner wall of the top of the observation cover 3. The upper support guide rail 302 and the lower support guide rail 103 are arranged symmetrically. The lower support guide rail 103 is fixed in the center of the bottom inner wall of the inner arc cover 101. When the observation cover 3 is closed with the test platform base 1, the lifting motor 203 drives the movable end cover 204 to slide down along the lifting guide column 201 through related accessories until the movable end cover 204 is connected to the fixed end cover 2. It synchronously drives the observation cover 3 to slide down until the upper extrusion mechanism 8 inside the observation cover 3 approaches the lower extrusion mechanism 4.

[0044] The top of the upper movable base 801 is slidably sleeved with the upper support guide rail 302. The bottom of the upper movable base 801 is provided with an inner telescopic frame 805 connected to the outer arc frame 802. The center of the bottom frame of the outer arc frame 802 is provided with an outer telescopic frame 803 connected to the inner telescopic frame 805. The bottom of the outer telescopic frame 803 is provided with an upper extrusion plate 804. The upper movable base 801 moves along the surface of the upper support guide rail 302, thereby driving the upper extrusion mechanism 8 and the lower extrusion mechanism 4 to move synchronously. The inner telescopic frame 805 drives the outer arc frame 802 to slide down synchronously. The inner telescopic frame 401 drives the arc bracket 402 to slide up synchronously, realizing the upper and lower docking. This causes the lower extrusion mechanism 4 and the upper extrusion mechanism 8 to be temporarily spliced ​​together to form a circular pressure bearing mechanism, which is used for multi-area synchronous extrusion test of the outer peripheral wall of the thin-walled aluminum profile frame.

[0045] Among them, the outer telescopic frame 803 drives the upper extrusion plate 804 to slide down, and its movement is synchronized with that of the lower extrusion plate 409, so as to realize the upper and lower coordinated pressure test of the thin-walled aluminum profile frame. When the side extrusion plate 408 is moved close to the thin-walled aluminum profile frame, the side telescopic frame 407 is used to drive them to move closer to each other, and the left and right coordinated pressure test is carried out on both sides of the thin-walled aluminum profile frame.

[0046] During the pressure test of the thin-walled aluminum profile frame, external testers can record and observe the test process in real time through the observation cover 3. The process of the thin-walled aluminum profile frame being squeezed can be directly seen through the observation cover 3 and the movable cover plate 301 acrylic transparent material, which is used to record the shape change of the frame under compression.

[0047] When the outer wall of the thin-walled aluminum profile frame is compressed and deformed, while its interior remains filled with test water, the test water is compressed along with the change in the size of the load environment. Combined with the local pressure on the surface of the thin-walled aluminum profile frame, cracks occur, causing the test water to overflow along the crack area. The test water leaves a mark after contacting the crack area, and at the same time, the test water falls onto the test paper 7 laid in the collection tank 102 below, causing the test paper 7 to become contaminated and change color. This helps to record the pressure state, deformation process and damage state of the thin-walled aluminum profile frame under pressure. The bottom of the collection tank 101 is provided with a pipe for connecting to the liquid storage tank for recycling the dripping test water.

[0048] Example 3: This example is a pressure bearing test fixture for a thin-walled aluminum profile frame, including a test monitoring system. A control panel is installed on the outer wall of the test platform base 1. High-definition recording sensors are installed on the inner walls of the test platform base 1 and the observation cover 3, which are adjacent to each other, to collect the frame deformation reference value generated by the thin-walled aluminum profile frame under test. A pressure sensor is installed inside the limiting extrusion plate 502 to collect the frame bearing internal deformation value generated by the thin-walled aluminum profile frame under test. An integrated sensor is installed on the bottom inner wall of the test platform base 1 to collect the abnormal leakage data value generated by the thin-walled aluminum profile frame under test. The collected frame deformation reference value, frame bearing internal deformation value, and abnormal leakage data value are sent to the cloud database via the control panel.

[0049] The testing and monitoring system is used to collect, record, analyze, and provide test results for the pressure testing of thin-walled aluminum profile frames inside the testing fixture. Figure 10 As shown, the test monitoring system first sets high-definition recording sensors on the inner walls of the adjacent connection between the test platform base 1 and the observation cover 3. The high-definition recording sensors in the test platform base 1 are located on the inner walls on both sides of the top of the inner arc cover 101. The high-definition recording sensors are used to collect the frame deformation reference values ​​generated by the test on the thin-walled aluminum profile frame.

[0050] The frame deformation reference value represents the value of the shrinkage of the outer surface of the thin-walled aluminum profile frame after being squeezed. The pressure sensor is installed inside the limiting extrusion plate 502. The pressure sensor is connected to the water inlet 505, and the water inlet 505 is installed inside the regulating valve. It is used to regulate the injection of test water, detect and prevent backflow under pressure, and collect the frame pressure deformation value generated by the thin-walled aluminum profile frame under test. The frame pressure deformation value represents the deformation of the thin-walled aluminum profile frame after being subjected to pressure.

[0051] After the internal test water is synchronously squeezed, the pressure change generated by the valve inside the water inlet 505 is measured. An integrated sensor is installed on the bottom inner wall of the test platform base 1. The integrated sensor consists of a humidity sensor and an industrial camera. The humidity sensor is installed inside the liquid collection tank 102 and covered with test paper 7. The industrial camera is installed on the bottom inner wall of both sides of the inner arc cover 101 and is used to collect the abnormal leakage data value generated by the test on the thin-walled aluminum profile frame. The abnormal leakage data value represents the number of times the internal test water drips onto the test paper when the thin-walled aluminum profile frame is squeezed and cracked.

[0052] The collected frame variable reference values, frame bearing internal variable values, and abnormal leakage data values ​​are sequentially labeled as KBi, KCi, and YLi, and then sent to the cloud database via the control panel. The above data is only the data for the current test. If the test is conducted at a different location or again, the relevant data needs to be readjusted.

[0053] After receiving the frame variable reference value KBi, the frame bearing internal variable value KCi, and the abnormal leakage data value YLi, the cloud database analyzes the test results of the testing fixture step by step, and uses this set of data to analyze the current test results, using the formula... Obtain the bearing capacity coefficient;

[0054] Where q, w, and e are the proportionality coefficients of the frame variable reference value KBi, the frame bearing capacity internal variable value KCi, and the abnormal leakage data value YLi, respectively, q > w > e > 0. R represents the bearing capacity coefficient. The proportionality coefficient is a parameter used to measure the contribution of the frame variable reference value KBi, the frame bearing capacity internal variable value KCi, and the abnormal leakage data value YLi to the bearing capacity coefficient. The proportionality coefficient represents the relative weight of each variable in the comprehensive result of calculating the bearing capacity coefficient, but it is not limited to this. The specific coefficient is adjusted according to the actual test. The preset bearing capacity coefficient YR is retrieved from the cloud database and compared with the bearing capacity coefficient R for analysis.

[0055] If the bearing capacity coefficient R > the preset bearing capacity coefficient YR, then the test is considered abnormal. At the same time, the thin-walled aluminum profile frame tested is marked as unqualified, generating a low-quality signal. The low-quality signal is sent to the display screen of the control panel with the text "Test No. 0013 / Low Quality / Data Record / Unqualified Mark" to remind the tester operating the test fixture to verify the test results, record the data, promptly remove the group of thin-walled aluminum profile frames, and clean the test fixture for the next group of thin-walled aluminum profile frames to be tested.

[0056] If the bearing capacity R < the preset bearing capacity YR, the test is considered normal, and the thin-walled aluminum profile frame is marked as qualified. A superior product signal is generated and sent to the control panel with text in the format of "Test No. 0013 / Quality Qualified / Data Retention / Second Test Required" to remind the tester to proceed with the next step based on the test results.

[0057] When a substandard signal is generated, the cloud database simultaneously marks the frame deformation reference value KBi, the frame bearing internal variable value KCi, and the abnormal leakage data value YLi that generated the substandard signal. It then retrieves pre-stored frame deformation sample values, frame bearing sample values, and abnormal leakage sample values ​​from the cloud database and compares them with the frame deformation reference value KBi, the frame bearing internal variable value KCi, and the abnormal leakage data value YLi for analysis.

[0058] If the frame deformation reference value KBi is not within the range of the frame deformation sample value, and the frame bearing capacity internal variable value KCi is within the range of the frame bearing capacity sample value, and the abnormal leakage data value YLi is less than the abnormal leakage sample value, then the thin-walled aluminum profile frame bearing capacity is determined to be unqualified, a first-level signal is generated and sent to the display of the control panel, and the text "Detection serial number 0013 / Frame bearing capacity small / Specific parameters retained" is displayed simultaneously, so that the testers can quickly know the abnormal points of the thin-walled aluminum profile frame.

[0059] If the frame deformation reference value KBi is within the range of the frame deformation sample value, and the frame bearing internal deformation value KCi is not within the range of the frame bearing sample value, and the abnormal leakage data value YLi is less than the abnormal leakage sample value, then the thin-walled aluminum profile frame material is determined to be defective, and the internal bearing pressure is insufficient. A secondary signal is generated and sent to the display on the control panel, which simultaneously displays the text in the style of "Detection serial number 0013 / material difference / specific parameters retained", so that the testers can quickly know the abnormal points of the thin-walled aluminum profile frame.

[0060] If the frame deformation reference value KBi is within the range of the frame deformation sample value, and the frame bearing internal deformation value KCi is within the range of the frame bearing sample value, and the abnormal leakage data value YLi is greater than the abnormal leakage sample value, then the thin-walled aluminum profile frame is determined to be easily damaged, a level 3 signal is generated, and it is sent to the display of the control panel, which simultaneously displays the text in the style of "Detection serial number 0013 / Frame easily damaged / Specific parameters retained", so that the testers can quickly know the abnormal points of the thin-walled aluminum profile frame.

[0061] As can be seen from Embodiments 1, 2, and 3, the clamping mechanism 5 and the lower extrusion mechanism 4 work together to achieve stable clamping and initial positioning of the thin-walled aluminum profile frame within the test platform base 1, ensuring accurate positioning during testing. The observation cover 3 and the movable cover plate 301 are made of acrylic material, allowing real-time observation of changes in the frame's shape during testing. The detection paper 7 in the liquid collection tank 102 displays the overflow of test water to determine if the frame is damaged. Multiple components work together to simultaneously perform extrusion tests on multiple areas of the frame.

[0062] The testing and monitoring system provides a basis for analysis through multi-sensor collaboration. It judges the test results by comparing the pressure coefficient with preset values, generates signals to feed back to the control panel, and generates different levels of signals and provides parameters for anomalies. The test data is sent to a cloud database for storage and traceability, and its pre-stored parameters provide a benchmark for comparative analysis.
