Description

Technical Field

[0001] This invention relates to the field of peel performance testing devices, and specifically to a device for testing the peel resistance of honeycomb panels. Background Technology

[0002] Honeycomb panels, with their excellent properties such as lightweight, high strength, sound insulation, heat insulation, earthquake resistance, and moisture resistance, have been widely used in aerospace, building decoration, transportation, and other fields. The adhesive strength of their sandwich structure directly determines the safety and service life of the product. Tensile peel testing is the core method for evaluating the peel resistance of honeycomb panels. By measuring parameters such as load and elongation during the peeling process, it can accurately reflect the adhesion force between the panel and the core material, providing crucial information for the quality control of honeycomb panels.

[0003] The honeycomb panel roller peel tester is a primary device for testing the strength of honeycomb panel sandwich structures. The machine uses roller clamps to test the adhesive strength of the honeycomb panels. In a standard roller peel test, one end of the panel to be peeled is fixed and wrapped around the roller surface, while the other end is fixed to the upper clamp of the testing machine. When the testing machine begins to stretch the loading tape, the roller rolls upwards, gradually peeling the panel from the sandwich structure. Due to the rigidity of the panel and the dynamic nature of the peeling process, when it is peeled from the core material and attempts to bend and wrap around the roller, the material's resistance to bending may create tiny gaps or incomplete adhesion between the panel and the roller surface. Simultaneously, changes in the adhesive's cohesive energy or interfacial adhesion may cause the peeling process to exhibit a "stick-slip" phenomenon (alternating pauses and sudden jumps), which instantaneously alters the panel's tension and affects its adhesion to the roller. These effects change the effective lever arm length, introduce additional bending resistance, and cause fluctuations in the load curve.

[0004] To eliminate the aforementioned interference, the industry commonly employs a blank test calibration method. This involves conducting a simulated test using a single-layer panel identical to the sandwich structure sample, excluding adhesive peeling. The measured force is termed the "resistance load." ).this This includes the force required to overcome factors such as panel bending stiffness and roller friction. This force needs to be subtracted from the total peel load when finally calculating the peel strength. Thus, a net load is obtained that is purely used to overcome the adhesive strength.

[0005] However, existing technologies typically employ a multi-stage peel test and blank test approach. When operators use clamps to hold the top and bottom ends of the honeycomb panel and the blank test panel, it is difficult to ensure that both panels are vertical. If either panel tilts, it directly changes the direction of force and introduces additional torque, resulting in inconsistent stress environments between the two tests. This ultimately leads to a large error in the peel strength calculation results, failing to accurately reflect the true peel resistance of the honeycomb panel. Summary of the Invention

[0006] This invention provides a device for testing the peel resistance of honeycomb panels, which solves the problem that existing testing devices cannot accurately reflect the true peel resistance of honeycomb panels due to clamping and positioning deviations in the panel of the honeycomb panel and the panel of the blank test.

[0007] The present invention provides a honeycomb panel peel resistance testing device with the following technical solution: A honeycomb panel peel resistance testing device is used to test honeycomb panels and single-layer panels. The honeycomb panel includes a main panel and a core material adhered to the main panel. The device includes a test bench, a mounting shell, a testing section, and a control section. The mounting shell is vertically movable and mounted on the test bench. The testing section includes an upper clamping group and a lower clamping group, with the upper clamping group located above the lower clamping group. The upper clamping group includes an upper clamping plate, an upper adjusting member, and an upper transmission member. The upper adjusting member is vertically movable and mounted inside the mounting shell. The upper transmission member is mounted on the upper adjusting member and can move relative to the upper adjusting member in a first... The upper clamping plate slides upwards and is mounted on the upper transmission component. It can move synchronously with the upper transmission component and can rotate relative to the upper transmission component around a second direction. Both the first and second directions are horizontal and perpendicular to each other. The lower clamping assembly includes a lower clamping plate, a lower transmission component, and a roller. The roller is set on the test bench along the first direction and can rotate around its own axis while moving upwards. The lower transmission component is mounted on the roller, and the lower clamping plate is mounted on the lower transmission component and can rotate relative to the lower transmission component around a second direction. The upper and lower ends of the main panel are connected to the upper clamping plate and the lower clamping plate, respectively. The structure and connection method of the control part are the same as those of the test part.

[0008] Furthermore, the upper clamping plate comprises two plates, which define a clamping space and are connected by a locking element; the structure and connection method of the lower clamping plate are the same as those of the upper clamping plate.

[0009] Furthermore, the upper adjusting member includes an adjusting plate, which is slidably mounted in the mounting housing via a first elastic member, the first elastic member being arranged in the vertical direction.

[0010] Furthermore, the upper clamping assembly also includes a clamping member, which includes two clamping blocks arranged face-to-face in the mounting housing along a second direction, defining a clamping space between the two clamping blocks. The clamping space is located below the clamping space, and the two clamping blocks in the test section are connected to the two clamping blocks in the control section by a force equalizing rod. The force equalizing rod is arranged along the second direction and slides with the clamping blocks. The adjusting plate is connected to the force equalizing rod through a second elastic member, which is arranged vertically and has an elastic coefficient greater than that of the first elastic member.

[0011] Furthermore, the upper transmission component includes a first transmission plate and a second transmission plate, which are arranged side by side in the second direction. Both the first and second transmission plates are slidably engaged with the adjusting plate, and the second transmission plate is connected to the first transmission plate through two first inserts. A third elastic element is provided between the first inserts and the first transmission plate, and the third elastic element is arranged along the second direction. Both plates of the upper clamping plate are provided with first mating grooves, which are arranged one-to-one with the first inserts. The first mating grooves are arc grooves, and the first inserts are arc-shaped blocks. The first inserts and their corresponding first mating grooves are slidably engaged.

[0012] Furthermore, the adjustment plate includes a main board and two sub-boards. Both sub-boards are mounted on the lower end of the main board, with one sub-board fixedly connected to the main board and the other sub-board slidably connected to the main board, allowing it to slide relative to the main board in a second direction. The first transmission plate and the second transmission plate are slidably mounted on the two sub-boards respectively.

[0013] Furthermore, the lower transmission component includes two second insert plates, which are arranged face to face in a first direction. The second insert plates are connected to the roller through second insert blocks, and a fourth elastic element is provided between the second insert blocks and the roller. The fourth elastic element is arranged along the second direction. The two plates of the lower clamping plate are each provided with a second mating groove. The second mating groove is arranged in a one-to-one correspondence with the second insert block. The second mating groove is an arc groove, and the second insert block is an arc block. The second insert block and the corresponding second mating groove are in sliding engagement.

[0014] Furthermore, both the first and second insert blocks are equipped with multiple ball bearings.

[0015] Furthermore, both ends of the roller are provided with flanges, and a take-up belt is wound around both flanges. In the initial state, the free end of the take-up belt is fixedly installed on the test table and kept taut.

[0016] Furthermore, the mounting shell is mounted on the test bench via a drive mechanism, which drives the mounting shell to move up and down on the test bench.

[0017] The beneficial effects of this invention are as follows: The honeycomb panel peel resistance testing device of this invention comprises a test bench, a mounting shell, a test section, and a control section. During the upward movement of the mounting shell, the upper ends of the main panel and the single-layer panel can move relative to their lower ends in a first direction and swing around a second direction. Simultaneously, the lower ends of the main panel and the single-layer panel can swing around the second direction, allowing the main panel and the single-layer panel to rotate from an inclined position to a vertical position first. This avoids additional torque and force interference introduced by clamping deviation, reducing testing errors and improving the accuracy of the test results. Furthermore, by setting up a test section and a control section with identical structures and connections, the clamping, fixing, calibration, and testing of the main panel (peel test) and the single-layer panel (blank test) can be achieved simultaneously. Repeated clamping and positioning operations are unnecessary; operators only need to install once to conduct both tests, significantly reducing operational difficulty and labor intensity, and improving testing efficiency.

Detailed Implementation

[0030] 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.

[0031] An embodiment of the honeycomb panel peel resistance testing device of the present invention, such as... Figures 1 to 10 As shown.

[0032] A device for testing the peel resistance of a honeycomb panel is provided for testing a honeycomb panel 100 and a single-layer panel 200. The honeycomb panel 100 is used for peel resistance testing, and the single-layer panel 200 is used for blank testing. The honeycomb panel 100 includes a main panel 110 and a core material 120 adhered to the main panel 110. The structure of the main panel 110 is the same as that of the single-layer panel 200.

[0033] The honeycomb panel peel resistance testing device includes a test bench 300, a mounting shell 400, a testing section 500, and a control section 600. The mounting shell 400 is vertically movable on the test bench 300. The testing section 500 includes an upper clamping assembly and a lower clamping assembly, with the upper clamping assembly located above the lower clamping assembly. The upper clamping assembly includes an upper clamping plate 510, an upper adjusting member 520, and an upper transmission member 530. The upper adjusting member 520 is vertically movable within the mounting shell 400. The upper transmission member 530 is mounted on the upper adjusting member 520 and can slide relative to the upper adjusting member 520 in a first direction. The upper clamping plate 510 is mounted on the upper transmission member 530, can move synchronously with the upper transmission member 530, and can rotate relative to the upper transmission member 530 around a second direction. Both the first and second directions are horizontal and perpendicular to each other. The lower clamping assembly includes a lower clamping plate 540, a lower transmission member 550, and a roller 560. The roller 560 is positioned on the test bench 300 along a first direction and can rotate and move upwards while maintaining its own axis. A lower transmission member 550 is mounted on the roller 560, and a lower clamping plate 540 is mounted on the lower transmission member 550 and can rotate relative to the lower transmission member 550 in a second direction. The upper and lower ends of the main panel 110 are connected to the upper clamping plate 510 and the lower clamping plate 540, respectively. The structure and connection method of the control section 600 are the same as those of the test section 500.

[0034] The mounting housing 400 is mounted on the test bench 300 via a driving component, which drives the mounting housing 400 to move up and down on the test bench 300. The driving component is existing technology and can specifically be a nut and screw mechanism.

[0035] During testing, the operator connects the top and bottom ends of the main panel 110 to the corresponding upper clamping plate 510 and lower clamping plate 540 in the test section 500, respectively. Then, the operator connects the top and bottom ends of the single-layer panel 200 to the corresponding upper clamping plate 510 and lower clamping plate 540 in the control section 600, respectively. At this time, the main panel 110 and / or the single-layer panel 200 may be tilted relative to the vertical direction. Then, the entire mounting shell 400 is driven to move upward. Taking the main panel 110 as an example, if the main panel 110 is tilted, during the upward movement of the mounting shell 400, the upper end of the main panel 110 can move relative to its lower end in the first direction and swing around the second direction. At the same time, the lower end of the main panel 110 can swing around the second direction, so that the main panel 110 first rotates from tilted to vertical, avoiding additional torque and force interference caused by clamping deviation, reducing detection error and improving the accuracy of detection results. Furthermore, by setting up the test section 500 and the control section 600 with identical structure and connection method, the clamping, fixing, calibration and detection of the main panel 110 (peeling test) and the single-layer panel 200 (blank test) can be realized simultaneously. There is no need to repeat clamping and positioning operations. Operators only need to install once to carry out two tests, which significantly reduces the difficulty of operation and labor intensity and improves detection efficiency.

[0036] In a further embodiment, the upper clamping plate 510 includes two plates defining a clamping space between them and connected by a locking member. The structure and connection method of the lower clamping plate 540 are the same as those of the upper clamping plate 510. The locking member is a bolt 511.

[0037] In a further embodiment, the upper adjusting member 520 includes an adjusting plate 521, which is slidably mounted in the mounting housing 400 via a first elastic member 522, which is arranged vertically. The first elastic member 522 is a spring.

[0038] The upper clamping assembly also includes a clamping member comprising two clamping blocks 570. The two clamping blocks 570 are arranged face-to-face within the mounting housing 400 along a second direction, defining a clamping space between them. This clamping space is located below the clamping space. The two clamping blocks 570 in the test section 500 and the two clamping blocks 570 in the control section 600 are connected by a force equalizing rod 580. The force equalizing rod 580 is arranged along the second direction and slides in engagement with the clamping blocks 570. The adjusting plate 521 is connected to the force equalizing rod 580 via a second elastic element 523. The second elastic element 523 is arranged vertically and is a spring, with its elastic coefficient greater than that of the first elastic element 522.

[0039] The mounting shell 400 has a dovetail groove at its lower end. The clamping member is set in a one-to-one correspondence with the dovetail groove. The two clamping blocks 570 of the clamping member slide in the dovetail groove, so that the two clamping blocks 570 can move closer to each other in the second direction as the mounting shell 400 moves upward, so that the clamping space gradually becomes smaller.

[0040] This embodiment continues to illustrate the main panel 110 as an example by setting the adjustment plate 521. During the upward movement of the mounting shell 400, the mounting shell 400 will drive the entire upper clamping assembly to move upward through the first elastic member 522. At this time, the first elastic member 522 is stretched, and the upper clamping assembly moves upward relatively more slowly, that is, the mounting shell 400 moves upward relative to the upper clamping assembly. The upward movement of the upper clamping assembly is also the upward movement of the upper clamping plate 510 and the upper transmission member 530. The upward movement of the upper clamping plate 510 will drive the upper end of the main panel 110 upward. If the main panel 110 is tilted at this time, during the upward movement of the mounting shell 400, the upper end of the main panel 110 will move relative to the lower end in the first direction and swing around the second direction. At this time, the lower end of the main panel 110 will be driven to swing around the second direction, so that the main panel 110 first rotates from tilted to vertical, and at this time the second elastic member 523 and the upper clamping assembly remain relatively stationary.

[0041] When the main panel 110 rotates to a vertical position, as the mounting shell 400 continues to move upward, the tension on the lower end of the main panel 110 will keep it stationary. At this point, the main panel 110 is rotated to a vertical position with no room for movement. The upper clamping assembly located at the upper end of the main panel 110 also remains stationary. The mounting shell 400 moves upward relative to the upper clamping assembly, and the first elastic element 522 continues to stretch and compress the second elastic element 523. The calibration process and principle of the single-layer panel 200 are the same as those of the main panel 110, and will not be repeated here. Furthermore, for the main panel 110 and the single-layer panel 200, when their tilt degrees are different, the adjusting plate 521 in the test section 500 and the adjusting plate 521 in the control section 600 will have a height difference in the vertical direction until both the main panel 110 and the single-layer panel 200 rotate from tilt to vertical. During this process, the elastic force generated by the compression of the second elastic element 523 will be spread out by the force equalizing rod 580, so that the entire detection device remains stable.

[0042] Furthermore, during the upward movement of the mounting shell 400, the two clamping blocks 570 within the same clamping component can approach each other in the second direction, gradually reducing the clamping space. After both the main panel 110 and the single-layer panel 200 are adjusted to be vertical, the main panel 110 and the single-layer panel 200 are clamped again at the same position, ensuring that the clamping positions at the upper ends of the main panel 110 and the single-layer panel 200 are consistent, further improving the accuracy of the test results.

[0043] In a further embodiment, the upper transmission member 530 includes a first transmission plate 531 and a second transmission plate 532, which are arranged side by side in a second direction. Both the first transmission plate 531 and the second transmission plate 532 are slidably engaged with the adjusting plate 521. The second transmission plate 532 is connected to the first transmission plate 531 via two first inserts 533. A third elastic member, which is a spring, is provided between the first inserts 533 and the first transmission plate 531 and is arranged along the second direction. The third elastic member always has a tendency to move the second transmission plate 532 towards the side closer to the first transmission plate 531 along the second direction. The upper clamping plate 510 has a first mating groove 512 on each of its two plates. The first mating groove 512 is corresponding to the first insert block 533. The first mating groove 512 is an arc groove, and the first insert block 533 is an arc block. The first insert block 533 and the corresponding first mating groove 512 are in sliding engagement. The two first mating grooves 512 and the two first insert blocks 533 are concentric, thereby enabling the two plates of the upper clamping plate 510 to rotate relative to the first transmission plate 531 and the second transmission plate 532 in a second direction.

[0044] Furthermore, the adjusting plate 521 includes a main plate 524 and two sub-plates 525. A first elastic member 522 connects the main plate 524 and the mounting shell 400. Both sub-plates 525 are mounted on the lower end of the main plate 524, with one sub-plate 525 fixedly connected to the main plate 524 and the other sub-plate 525 slidably connected to the main plate 524, allowing it to slide relative to the main plate 524 in a second direction. A first transmission plate 531 and a second transmission plate 532 are slidably mounted on the two sub-plates 525, respectively.

[0045] By sliding one of the sub-boards 525 to the main board 524, it is possible to adapt to main panels 110 and single-layer panels 200 of different thicknesses. Of course, when the thickness of the clamped main panel 110 and single-layer panel 200 is fixed, both sub-boards 525 can also be fixed to the main board 524.

[0046] In a further embodiment, the lower transmission member 550 includes two second insert plates 551, which are arranged face to face in a first direction. Both second insert plates 551 are arc-shaped plates. The second insert plates 551 are connected to the roller 560 through second insert blocks 552. A fourth elastic member 553 is provided between the second insert blocks 552 and the roller 560. The fourth elastic member 553 is arranged along a second direction and is a spring. The fourth elastic member 553 causes the second insert plates 551 to always have a tendency to move towards the side closer to the roller 560 along the second direction.

[0047] The two plates of the lower clamping plate 540 are each provided with a second mating groove 541. The second mating groove 541 and the second insert block 552 are respectively arranged one-to-one. The second mating groove 541 is an arc groove and the second insert block 552 is an arc block. The second insert block 552 and the corresponding second mating groove 541 are slidably engaged. The two second mating grooves 541 and the two second insert blocks 552 are concentric, so that the two plates of the lower clamping plate 540 can rotate about the second direction relative to the two second insert plates 551.

[0048] In a further embodiment, both the first insert block 533 and the second insert block 552 are provided with a plurality of balls 554.

[0049] By setting the ball bearing 554, the friction between the first insert block 533 and its corresponding first mating groove 512, and between the second insert block 552 and its corresponding second mating groove 541, is reduced.

[0050] In a further embodiment, both ends of the roller 560 are provided with flanges, and a take-up belt 561 is wound around both flanges. In the initial state, the free end of the take-up belt 561 is fixedly installed on the test bench 300 and kept taut.

[0051] After the main panel 110 is adjusted, the mounting shell 400 will move the main panel 110 upward as a whole. At this time, the roller 560 will rotate around its own axis and move upward, while the winding tape 561 will be extended to adapt to the change in height. The roller 560 will gradually peel the main panel 110 off from the core material 120 and wrap it around the surface of the roller 560 until the test ends.

[0052] Based on the above embodiments, the specific working process is as follows:

[0053] During testing, the operator passes the upper end of the main panel 110 through the clamping space and connects the upper and lower ends of the main panel 110 to the corresponding upper clamping plate 510 and lower clamping plate 540 in the test section 500, respectively. Then, the upper and lower ends of the single-layer panel 200 are connected to the corresponding upper clamping plate 510 and lower clamping plate 540 in the control section 600, respectively. At this time, the main panel 110 and / or the single-layer panel 200 may be tilted relative to the vertical direction.

[0054] Then, the entire mounting shell 400 is driven to move upward. Taking the main panel 110 as an example, during the upward movement of the mounting shell 400, the mounting shell 400 will drive the entire upper clamping assembly to move upward through the first elastic element 522. At this time, the first elastic element 522 is stretched, and the upper clamping assembly moves upward relatively more slowly, that is, the mounting shell 400 moves upward relative to the upper clamping assembly. The upward movement of the upper clamping assembly is also the upward movement of the upper clamping plate 510 and the upper transmission element 530. The upward movement of the upper clamping plate 510 will drive the upper end of the main panel 110 upward. If the main panel 110 is tilted at this time, during the upward movement of the mounting shell 400, the upper end of the main panel 110 will move relative to the lower end in the first direction and swing around the second direction. At this time, the lower end of the main panel 110 will be driven to swing around the second direction, so that the main panel 110 first rotates from tilted to vertical, and at this time the second elastic element 523 and the upper clamping assembly remain relatively stationary.

[0055] When the main panel 110 rotates to a vertical position, as the mounting shell 400 continues to move upward, the tension on the lower end of the main panel 110 will keep it stationary. At this point, the main panel 110 is rotated to a vertical position with no room for movement. The upper clamping assembly located at the upper end of the main panel 110 also remains stationary. The mounting shell 400 moves upward relative to the upper clamping assembly, and the first elastic element 522 continues to stretch and compress the second elastic element 523. The calibration process and principle of the single-layer panel 200 are the same as those of the main panel 110, and will not be repeated here. Furthermore, for the main panel 110 and the single-layer panel 200, when their tilt degrees are different, the adjusting plate 521 in the test section 500 and the adjusting plate 521 in the control section 600 will have a height difference in the vertical direction until both the main panel 110 and the single-layer panel 200 rotate from tilt to vertical. During this process, the elastic force generated by the compression of the second elastic element 523 will be spread out by the force equalizing rod 580, so that the entire detection device remains stable.

[0056] Furthermore, during the upward movement of the mounting shell 400, the two clamping blocks 570 within the same clamping component can approach each other in the second direction, gradually reducing the clamping space. After both the main panel 110 and the single-layer panel 200 are adjusted to be vertical, the main panel 110 and the single-layer panel 200 are clamped again at the same position, ensuring that the clamping positions at the upper ends of the main panel 110 and the single-layer panel 200 are consistent, further improving the accuracy of the test results.

[0057] After the main panel 110 is adjusted, the mounting shell 400 will move the main panel 110 upward as a whole. At this time, the roller 560 will rotate around its own axis and move upward, while the winding tape 561 will be extended to adapt to the change in height. The roller 560 will gradually peel the main panel 110 off from the core material 120 and wrap it around the surface of the roller 560 until the test ends.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
