Description

Technical Field

[0001] The present invention belongs to the technical field of aluminum alloy window testing, and in particular relates to a structural strength testing device and method for an aluminum alloy window using photovoltaic glass. Background Art

[0002] With the acceleration of urbanization and the advancement of construction technology, modern buildings’ requirements for doors and windows are no longer limited to basic wind and rain protection functions, but focus more on safety, energy efficiency, comfort and aesthetics. Aluminum alloy windows, as an important part of the building’s exterior envelope, need to withstand the effects of natural environmental factors such as wind loads, rainwater penetration, temperature changes, as well as various loads in daily use (such as opening and closing forces, impact forces, etc.).

[0003] Early assessments of aluminum window structural strength relied heavily on manual experience, using simple load application (such as manual pushing, pulling, and tapping) and visual observation to determine performance. This approach lacked quantitative data and scientific evidence. This method was subject to significant errors and low efficiency, failing to accurately reflect the true performance of aluminum windows under complex operating conditions and potentially leading to quality risks. Existing aluminum window structural strength testing devices generally come in two types: continuous pressure testing and rapid stamping testing. Existing aluminum window structural strength testing devices lack the flexibility to adjust the test position, failing to cover multiple areas, such as the window frame and sash. Fixed support structures only allow for testing at a single location, requiring manual disassembly and assembly of the specimen to change test points. This is cumbersome and prone to specimen damage from repeated clamping, reducing test efficiency and data integrity. Furthermore, the aluminum window cannot be precisely fixed to the center of the device, and manual alignment can easily result in angular deviations. Specimen skew during testing can lead to uneven load distribution, causing test results to deviate from the true value. For example, uneven force on the window frame during wind pressure testing can cause premature deformation, obscuring its actual strength performance. Therefore, improvements are needed to address these issues. Summary of the Invention

[0015] A method for testing a structural strength test device for an aluminum alloy window using photovoltaic glass, comprising the following steps:

[0016] Step 1: First, connect all electrical devices in the device to the wires and power on. Then, push the aluminum alloy window to be tested into the test box through the feed port of the test box. When the aluminum alloy window is pushed in, start the electric push rod to push the support plate upward, and support the aluminum alloy window through the support plate. After the support plate supports the aluminum alloy window, the electric push rod controls the support plate to descend, thereby controlling the aluminum alloy window to descend. At this time, the aluminum alloy window falls on the surrounding support rods, and all the support rods are in a horizontal state.

[0017] Step 2: After the aluminum alloy window falls on the supporting rod, the four second servo motors are started at the same time. The second servo motor drives the driving wheel to rotate, and the driving wheel drives the driven wheel to rotate through the belt. The driven wheel drives the rotating seat to rotate through two semicircular rubber strips that are embedded with each other. Since the rotating seat is screwed to the propulsion screw, the propulsion screw is driven to slide along its axial direction, and the propulsion screw drives the push plate to slide inside the positioning port; the four push plates slide toward the inside of the positioning port at the same time until the four push plates are in contact with the four sides of the aluminum alloy window, and the aluminum alloy window is pushed by the four push plates, thereby positioning the aluminum alloy window;

[0018] Step three, when the aluminum alloy window is positioned, stop the second servo motor, and then adjust the supporting quantity of the supporting rods at the four ends according to the position of the aluminum alloy window to be tested; when the middle of the aluminum alloy window needs to be tested, control the electric push rod to descend, thereby controlling the supporting plate to no longer support the middle of the aluminum alloy window; when the four ends of the aluminum alloy window need to be tested, control the electric push rod to rise, thereby controlling the supporting plate to support the middle of the aluminum alloy window, and start the first servo motor in the middle of the four sides. The first servo motor drives the worm to rotate, the worm drives the worm gear to rotate, and the worm gear drives the adjusting screw to rotate. Since the adjusting screw is screwed to the moving seat, the moving seat in the middle of the four sides is driven to slide downward on the adjusting screw, and the moving seat drives the supporting rod in the middle of the four sides to rotate downward through the connecting rod, and the aluminum alloy window is supported by the two supporting rods on the outside of the four sides and the supporting plate at the center;

[0019] Step 4: After determining the position of the aluminum alloy window test, start the first stepper motor and the second stepper motor, and respectively control the first positioning screw and the second positioning screw to rotate through the first stepper motor and the second stepper motor, thereby controlling the first connecting block and the second connecting block to move, the two first connecting blocks drive the first moving shaft to move forward and backward, the two second connecting blocks drive the second moving shaft to move left and right, the first moving shaft and the second moving shaft drive the column to move horizontally in the test box, and then control the movement of the connecting plate in the test box; when the position of the connecting plate is moved, adjust the test mode of the aluminum alloy window, start the third stepper motor, and control The connecting plate is controlled to rotate, thereby controlling the hydraulic cylinder and the air cylinder at the lower end to rotate and adjust the position. When the hydraulic cylinder rotates to the test position, the aluminum alloy window is tested by continuously applying pressure through the hydraulic cylinder, and the telescopic end of the hydraulic cylinder is controlled to lower the pressure at the test position of the aluminum alloy window. The maximum pressure that the aluminum alloy window can withstand is monitored by the pressure sensor. When the cylinder rotates to the test position, the aluminum alloy window is hit by the cylinder, and the cylinder is started to make the punch fall quickly to test the impact resistance of the aluminum alloy window. After the test is completed, the electric push rod is started to push the aluminum alloy window upward, and then the aluminum alloy window is taken out, and finally all electrical equipment is powered off.

[0020] The beneficial effects of the present invention compared to the prior art are:

[0021] 1. The present invention facilitates adjustment according to the test position required for the aluminum alloy window through the cooperation of the supporting rod and the supporting plate, thereby increasing the diversity of the test position of the aluminum alloy window; and through the cooperation of the worm gear and the worm, it facilitates the supporting rod to fully withstand the pressure during pressurization and stamping of the device, thereby avoiding the supporting rod from tilting when subjected to high pressure, thereby affecting the test data; through the cooperation of the electric push rod and the supporting plate, it facilitates the loading and unloading of the aluminum alloy window, thereby avoiding the aluminum alloy window from being stuck in the device after testing.

[0022] 2. The present invention facilitates positioning of the aluminum alloy window at the center of the device through the cooperation of the push plate and the advancing screw rod, so that the aluminum alloy window is straightened, which is convenient for subsequent testing results; through the cooperation of the driven wheel, the rotating seat and the semicircular rubber strip, when the push plate is pushed inward to the top, the driven wheel is caused to idle, thereby avoiding rigid collision between the push plate and the aluminum alloy window, and improving subsequent testing results.

[0023] 3. The present invention facilitates the rapid positioning of the hydraulic cylinder and the air cylinder through the cooperation of the first positioning screw and the second positioning screw, thereby improving the testing efficiency of the aluminum alloy window; through the cooperation of the column and the third stepper motor, it is convenient to control the rotation of the connecting plate and the switching between test pressurization and rapid stamping, thereby improving the testing efficiency of the aluminum alloy window; through the cooperation of the pressure sensor and the punch, it is convenient to stamp the test position of the aluminum alloy window and also convenient to monitor the maximum pressure value that the aluminum alloy window can withstand, thereby enriching the testing means.

[0038] The base 1 is a horizontally mounted square plate-like structure, and the test box 2 is a square box-like structure with an open top. The test box 2 is fixedly mounted at the center of the upper end of the base 1. A horizontal square feed port 45 is provided on the front side wall of the test box 2 near the upper end. The feed port 45 is located above the front push plate 15.

[0039] The supporting assembly further includes an adjusting screw 9 , a worm wheel 10 , a worm 11 , a first servo motor 12 , a moving seat 13 , and a connecting rod 14 .

[0040] The telescopic end of the electric push rod 6 is vertically upward. The support plate 7 is a horizontally arranged circular plate structure. The telescopic end of the electric push rod 6 is fixedly connected to the center of the lower end surface of the support plate 7, and the support plate 7 is driven to rise and fall by the electric push rod 6.

[0041] The positioning frame 4 is a horizontally arranged square frame structure. Three support rods 8 are rotatably mounted in the middle of the inner side of each frame edge of the positioning frame 4. These support rods 8 are arranged along the length of the corresponding frame edge, with the length of each support rod 8 perpendicular to the length of the corresponding frame edge. One end of each support rod 8 is rotatably connected to the inner side of the corresponding frame edge. Three vertical adjustment screws 9 are rotatably mounted on the lower end of each frame edge of the positioning frame 4. The upper ends of the adjustment screws 9 are rotatably connected to the lower end of the positioning frame 4, and the lower ends of the adjustment screws 9 are rotatably connected to the inner bottom surface of the test box 2. A movable seat 13 is screwed onto each adjustment screw 9, and the three movable seats 13 correspond one-to-one with the three support rods 8 on the same side. A connecting rod 14 is rotatably mounted on each movable seat 13, and the end of the connecting rod 14 away from the movable seat 13 is rotatably connected to the end of the corresponding support rod 8 away from the positioning frame 4. The corresponding adjusting screws 9, connecting rods 14, and supporting rods 8 are located in the same plane. A worm gear 10 is fixedly sleeved on the lower end of each adjusting screw 9. A first servo motor 12 is mounted on one side of the lower end of each adjusting screw 9. A worm 11 is fixedly mounted on the output shaft of the first servo motor 12 and meshes with the worm gear 10 on the corresponding adjusting screw 9.

[0042] First servo motor 12 rotates worm 11, which in turn rotates worm wheel 10, which in turn rotates adjusting screw 9. Since adjusting screw 9 is threadedly connected to movable seat 13, movable seat 13 slides on adjusting screw 9. When movable seat 13 slides upward, it drives supporting rod 8 upward via connecting rod 14. When movable seat 13 slides downward, it drives supporting rod 8 downward via connecting rod 14. By individually controlling the operation of each first servo motor 12, the rotation of a specific supporting rod 8 can be controlled.

[0043] A horizontal protective plate 5 is fixedly installed inside the test box 2. The protective plate 5 is located below the supporting plate 7. A plurality of avoidance grooves are provided on the protective plate 5. The avoidance grooves are used to avoid the telescopic ends of the supporting rod 8 and the electric push rod 6.

[0044] The positioning assembly further includes a propulsion screw 17 , a rotating seat 18 , a rotating block 19 , a driven wheel 20 , a belt 21 , a semicircular rubber strip 22 , and a second servo motor 23 .

[0045] A horizontal square positioning port is provided on each of the four side walls of the test box 2, and a push plate 15 is slidingly provided inside each positioning port. The push plate 15 is a horizontally arranged rectangular parallelepiped structure. A rubber plate 16 is fixedly provided on the inner side surface of each push plate 15. A propulsion screw 17 is fixedly provided at one end of the outer side of each push plate 15, and the axis of the propulsion screw 17 is perpendicular to the side wall where the push plate 15 is located. A circular rotating seat 18 is screwed on the outer side of each propulsion screw 17, and a circular rotating groove is provided on the end face of the rotating seat 18 close to the positioning port. The cross section of the rotating groove is an L-shaped structure. Two upper and lower arc-shaped rotating blocks 19 are fixedly provided on the outer side of each positioning port. The cross section of the rotating block 19 is an L-shaped structure. Both rotating blocks 19 are rotatably provided inside the rotating groove of the rotating seat 18 outside the positioning port. A driven wheel 20 is sleeved on the outside of each rotating seat 18. A semicircular rubber strip 22 is fixedly mounted on the inner cylindrical surface of the driven wheel 20, and a semicircular rubber strip 22 is fixedly mounted on the outer cylindrical surface of the rotating seat 18. The semicircular rubber strip 22 on the inner side of the driven wheel 20 and the semicircular rubber strip 22 on the outer side of the rotating seat 18 interlock with each other. A second servo motor 23 is fixedly mounted on the upper end surface of the base 1 below each propulsion screw 17. A driving wheel is fixedly mounted on the output shaft of the second servo motor 23. A belt 21 is sleeved between the driving wheel and the driven wheel 20.

[0046] The second servo motor 23 drives the driving wheel to rotate, which in turn drives the driven wheel 20 to rotate via the belt 21. The driven wheel 20 drives the rotating seat 18 to rotate via two semicircular rubber strips 22 that fit together. Since the rotating seat 18 is screwed to the propulsion screw 17, it drives the propulsion screw 17 to slide along its axis, and the propulsion screw 17 drives the push plate 15 to slide inside the positioning port. When the aluminum alloy window is placed inside the test box 2, the four second servo motors 23 are controlled to operate synchronously, causing the four push plates 15 to slide toward the inside of the positioning port at the same time until the four push plates 15 contact the four sides of the aluminum alloy window. The aluminum alloy window is then pushed by the four push plates 15, thereby positioning the aluminum alloy window. By providing a rubber plate 16 on the push plate 15, damage to the aluminum alloy window during the pushing process is prevented. When the aluminum alloy window is positioned, the push plate 15 can no longer push the aluminum alloy window. At this time, the second servo motor 23 continues to rotate, so the semicircular rubber strip 22 on the driven wheel 20 and the semicircular rubber strip 22 on the rotating seat 18 begin to rotate relative to each other and slip, no longer driving the rotating seat 18 to rotate, and the push plate 15 no longer continues to push the aluminum alloy window.

A fixed first guide rod 25 and a rotatable first positioning screw 26 are disposed between the two first positioning blocks 24 on the right side. The first guide rod 25 and the first positioning screw 26 are both arranged horizontally along the front-to-back direction. A first connecting block 28 is threadedly connected to the outside of each first positioning screw 26. The first connecting block 28 slides over the outside of the first guide rod 25 on the same side. The two first connecting blocks 28 are symmetrically disposed, and a first horizontal movable shaft 34 is fixedly disposed between the two first connecting blocks 28. Two first stepper motors 27 are fixedly disposed on the rear side of the test box 2. The output shafts of the two first stepper motors 27 are respectively fixedly connected to the rear ends of the two first positioning screws 26.

[0051] A fixed second guide rod 30 and a rotatable second positioning screw 31 are disposed between the two second positioning blocks 29 on the front side. A fixed second guide rod 30 and a rotatable second positioning screw 31 are disposed between the two second positioning blocks 29 on the rear side. The second guide rod 30 and the second positioning screw 31 are both disposed horizontally in the left-right direction. A second connecting block 33 is threadedly connected to the outside of each second positioning screw 31. The second connecting block 33 slides onto the outside of the second guide rod 30 on the same side. The two second connecting blocks 33 are symmetrically disposed front to back.

The output shafts of the two second stepper motors 32 are respectively fixedly connected to the right ends of the two second positioning screws 31.

[0052] The upright post 36 remains upright and is slidably coupled to the outside of the first movable shaft 34 and the second movable shaft 35. A recessed mounting slot is provided at the lower end of the upright post 36. A third stepper motor 40 is fixedly mounted within the slot. The output shaft of the third stepper motor 40 points vertically downward, and the connecting plate 39 is fixedly mounted on the output shaft of the third stepper motor 40. The connecting plate 39 is a horizontally arranged circular plate-like structure. The center of the upper end surface of the connecting plate 39 is fixedly connected to the output shaft of the third stepper motor 40.

[0053] The two first stepper motors 27 rotate the two first positioning screws 26. Since the first positioning screws 26 are threadedly connected to the first connecting blocks 28, they cause the two first connecting blocks 28 to slide on the two first guide rods 25, and the two first connecting blocks 28 drive the first movable shaft 34 to move back and forth. The two second stepper motors 32 rotate the two second positioning screws 31. Since the second positioning screws 31 are threadedly connected to the second connecting blocks 33, they cause the two second connecting blocks 33 to slide on the two second guide rods 30, and the two second connecting blocks 33 drive the second movable shaft 35 to move back and forth. The first movable shaft 34 and the second movable shaft 35 synchronously drive the column 36 to move horizontally, and the column 36 drives the lower connecting plate 39, as well as the hydraulic cylinder 41 and the pneumatic cylinder 42, to move horizontally.

[0054] A vertical first support column 37 is provided on each left and right side of the upright column 36. Both first support columns 37 are slidably mounted on the outside of the first movable shaft 34. A vertical second support column 38 is provided on each front and rear side of the upright column 36. Both second support columns 38 are slidably mounted on the outside of the second movable shaft 35. Adjacent first support columns 37 and second support columns 38 are fixedly connected by connecting rods 14. A circular arc-shaped T-slot is provided at the lower end of each first support column 37 and second support column 38. A circular annular T-block is fixedly mounted on the upper end surface of the connecting plate 39. The T-block slides and engages within the four T-slots.

[0055] Two left-right symmetrical hydraulic cylinders 41 are fixedly provided on the lower end surface of the connecting plate 39, and the telescopic ends of the hydraulic cylinders 41 are vertically downward. Two front-back symmetrical cylinders 42 are fixedly provided on the lower end surface of the connecting plate 39, and the telescopic ends of the cylinders 42 are vertically downward.

[0056] The second stepper motor 32 drives the connecting plate 39 and the hydraulic cylinder 41 and the air cylinder 42 at the lower end of the connecting plate 39 to rotate, thereby adjusting the positions of the hydraulic cylinder 41 and the air cylinder 42. When the connecting plate 39 rotates, a circle of T-shaped blocks on the connecting plate 39 slides inside the T-shaped slots at the lower ends of the first support column 37 and the second support column 38, thereby ensuring the stability of the connecting plate 39 during rotation.

[0057] The present invention also proposes a testing method for a structural strength testing device of an aluminum alloy window using photovoltaic glass, comprising the following steps:

[0058] Step 1: First, connect all electrical equipment in the device to wires and power on, then push the aluminum alloy window to be tested into the test box 2 through the feed port 45 of the test box 2. When the aluminum alloy window is pushed in, start the electric push rod 6, and push the supporting plate 7 upward through the electric push rod 6 to support the aluminum alloy window through the supporting plate 7; after the supporting plate 7 supports the aluminum alloy window, the electric push rod 6 controls the supporting plate 7 to descend, and then controls the aluminum alloy window to descend. At this time, the aluminum alloy window falls on the supporting rods 8 around it, and at this time all the supporting rods 8 are in a horizontal state.

[0059] Step 2: After the aluminum alloy window falls onto the support rod 8, the four second servo motors 23 are started simultaneously. The second servo motors 23 drive the driving wheel to rotate, which in turn drives the driven wheel 20 to rotate via the belt 21. The driven wheel 20 drives the rotating seat 18 to rotate via two semicircular rubber strips 22 that fit together. Since the rotating seat 18 is screwed to the propulsion screw 17, it drives the propulsion screw 17 to slide along its axis, and the propulsion screw 17 drives the push plate 15 to slide inside the positioning port. The four push plates 15 slide toward the inside of the positioning port simultaneously until the four push plates 15 contact the four sides of the aluminum alloy window. The aluminum alloy window is pushed by the four push plates 15, thereby positioning the aluminum alloy window. Since the lengths of the aluminum alloy windows are different, it is necessary to control the continuous advancement of the push plates 15 on all sides. When the aluminum alloy window is positioned, the push plate 15 can no longer push the aluminum alloy window. At this time, the second servo motor 23 continues to rotate, so the semicircular rubber strip 22 on the driven wheel 20 and the semicircular rubber strip 22 on the rotating seat 18 begin to rotate relative to each other, and the driven wheel 20 begins to idle and no longer drives the rotating seat 18 to rotate, and the push plate 15 no longer continues to push the aluminum alloy window.

[0060] Step three, when the aluminum alloy window is positioned, stop the second servo motor 23, and then adjust the supporting quantity of the supporting rods 8 at the four ends according to the position of the aluminum alloy window to be tested. When the middle of the aluminum alloy window needs to be tested, control the electric push rod 6 to descend, thereby controlling the supporting plate 7 to no longer support the middle of the aluminum alloy window; when the four ends of the aluminum alloy window need to be tested, control the electric push rod 6 to rise, thereby controlling the supporting plate 7 to support the middle of the aluminum alloy window, and start the first servo motor 12 in the middle of the four sides. The first servo motor 12 drives the worm 11 to rotate, the worm 11 drives the worm wheel 10 to rotate, and the worm wheel 10 drives the adjusting screw 9 to rotate. Since the adjusting screw 9 is screwed to the moving seat 13, the moving seat 13 in the middle of the four sides is driven to slide downward on the adjusting screw 9. The moving seat 13 drives the supporting rods 8 in the middle of the four sides to rotate downward through the connecting rod 14. The aluminum alloy window is supported by the two supporting rods 8 on the outside of the four sides and the supporting plate 7 in the center.

[0061] Step 4: After determining the position of the aluminum alloy window test, start the first stepper motor 27 and the second stepper motor 32, and respectively control the first positioning screw 26 and the second positioning screw 31 to rotate through the first stepper motor 27 and the second stepper motor 32, thereby controlling the first connecting block 28 and the second connecting block 33 to move. The two first connecting blocks 28 drive the first movable shaft 34 to move forward and backward, and the two second connecting blocks 33 drive the second movable shaft 35 to move left and right. The first movable shaft 34 and the second movable shaft 35 drive the column 36 to move horizontally in the test box 2, thereby controlling the connection plate 39 to move in the test box 2; when the position of the connection plate 39 is moved, adjust the test mode of the aluminum alloy window and start the third stepper motor 27. The stepper motor 40 controls the rotation of the connecting plate 39, and then controls the hydraulic cylinder 41 and the air cylinder 42 at the lower end to rotate and adjust the position. When the hydraulic cylinder 41 rotates to the test position, the aluminum alloy window is tested by continuously applying pressure through the hydraulic cylinder 41, and the telescopic end of the hydraulic cylinder 41 is controlled to lower the pressure at the test position of the aluminum alloy window, and the maximum pressure that the aluminum alloy window can withstand is monitored by the pressure sensor 43; when the cylinder 42 rotates to the test position, the aluminum alloy window is hit by the cylinder 42, and the cylinder 42 is started to make the punch 44 fall quickly to test the impact resistance of the aluminum alloy window; after the test is completed, the electric push rod 6 is started to push the aluminum alloy window upward, and then the aluminum alloy window is taken out, and finally all electrical equipment is powered off.
