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 using a single-layer panel identical to the sandwich structure sample to conduct a simulated test without 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, the prior art usually adopts a split way to carry out the peeling test and the blank test, but when the operator clamps the upper and lower ends of the panel of the honeycomb panel and the upper and lower ends of the panel for the blank test by using the clamp, it is difficult to ensure that the panel of the honeycomb panel and the panel for the blank test are both vertical, and once the two are inclined, the stress direction will be directly changed, additional torque will be introduced, the stress environment of the two tests will be inconsistent, and finally the calculation result of the peeling strength will have a large error, which cannot accurately reflect the real peeling resistance of the honeycomb panel. SUMMARY

[0021] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0022] An embodiment of the honeycomb panel anti-peeling performance detection device of the present application is shown in Figures 1 to 10

[0023] A honeycomb panel anti-peeling performance detection device is used to detect a honeycomb panel 100 and a single-layer panel 200, wherein the honeycomb panel 100 is used for peeling performance test, and the single-layer panel 200 is used for blank test. The honeycomb panel 100 comprises a main panel 110 and a core material 120 adhered to the main panel 110, and the structure of the main panel 110 is the same as that of the single-layer panel 200.

[0024] The honeycomb panel anti-peeling performance detection device comprises a test table 300, a mounting shell 400, a test part 500 and a control part 600. The mounting shell 400 is movably installed on the test table 300, the test part 500 comprises an upper clamping group and a lower clamping group, and the upper clamping group is located above the lower clamping group. The upper clamping group comprises an upper clamping plate 510, an upper adjusting part 520 and an upper driving part 530, the upper adjusting part 520 is movably installed in the mounting shell 400, the upper driving part 530 is installed on the upper adjusting part 520 and can slide in a first direction relative to the upper adjusting part 520, the upper clamping plate 510 is installed on the upper driving part 530 and can move synchronously with the upper driving part 530 and rotate around a second direction relative to the upper driving part 530, the first direction and the second direction are both horizontal directions and perpendicular to each other. The lower clamping group comprises a lower clamping plate 540, a lower driving part 550 and a roller 560. The roller 560 is arranged along the first direction on the test table 300 and can rotate around its own axis and move upward. The lower driving part 550 is installed on the roller 560, and the lower clamping plate 540 is installed on the lower driving part 550 and can rotate around the second direction relative to the lower driving part 550. The upper and lower ends of the main panel 110 are connected with the upper clamping plate 510 and the lower clamping plate 540 respectively. The structure and connection mode of the control part 600 are the same as those of the test part 500.

[0025] The mounting shell 400 is installed on the test table 300 through a driving part, and the driving part is used to drive the mounting shell 400 to move up and down on the test table 300. The driving part is a prior art, and a nut and screw mechanism can be specifically used.

[0026] When detecting, the operator connects the upper and lower ends of the main panel 110 with the upper and lower clamping plates 510 and 540 respectively arranged in the test part 500 corresponding thereto, and then connects the upper and lower ends of the single-layer panel 200 with the upper and lower clamping plates 510 and 540 respectively arranged in the control part 600 corresponding thereto. At this time, the main panel 110 and / or the single-layer panel 200 can be arranged obliquely 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 arranged obliquely, in the process of moving the mounting shell 400 upward, the upper end of the main panel 110 can move in the first direction and swing around the second direction relative to the lower end thereof, and at this time the lower end of the main panel 110 can swing around the second direction, so that the main panel 110 is first rotated from oblique to vertical, avoiding the additional torque and stress interference introduced by clamping deviation, reducing the detection error and improving the accuracy of the detection result. By arranging the test part 500 and the control part 600 which have the same structure and connection mode, the clamping and fixing, calibration and detection of the main panel 110 (peeling test) and the single-layer panel 200 (blank test) are simultaneously realized, without the need for repeated clamping and positioning operations. The operator only needs to install once to carry out two tests, which significantly reduces the operation difficulty and labor intensity and improves the detection efficiency.

[0027] In further embodiments, the upper clamping plate 510 includes two plate bodies, and the clamping space is defined between the two plate bodies and connected by a locking member. The structure and connection mode of the lower clamping plate 540 are the same as those of the upper clamping plate 510. The locking member is a bolt 511.

[0028] In further embodiments, the upper adjusting member 520 includes an adjusting plate 521, which is slidingly installed in the mounting shell 400 by a first elastic member 522 arranged in the vertical direction. The first elastic member 522 is a spring.

[0029] The upper clamping group further includes a clamping member, which includes two clamping blocks 570 arranged face to face in the mounting shell 400 along the second direction, and a clamping space is defined between the two clamping blocks 570. The clamping space is located below the clamping space, and the two clamping blocks 570 in the test part 500 and the two clamping blocks 570 in the control part 600 are connected by a uniform force rod 580. The uniform force rod 580 is arranged along the second direction and slidingly cooperates with the clamping blocks 570. The adjusting plate 521 is connected with the uniform force rod 580 by a second elastic member 523 arranged in the vertical direction. The second elastic member 523 is a spring, and the elastic coefficient of the second elastic member 523 is greater than that of the first elastic member 522.

[0030] The mounting shell 400 is provided with a dovetail groove at the lower end, and the clamping pieces are arranged one by one in the dovetail groove. The two clamping blocks 570 of the clamping piece are in sliding fit with the dovetail groove, so that the two clamping blocks 570 can move close to each other in the second direction during the upward movement of the mounting shell 400, and the clamping space gradually becomes smaller.

[0031] The adjustment plate 521 is arranged, and the main panel 110 is taken as an example for description. During the upward movement of the mounting shell 400, the mounting shell 400 drives the whole upper clamping group to move upward through the first elastic member 522, and at this time, the first elastic member 522 is stretched, and the upper clamping group moves upward relatively slower, that is, the mounting shell 400 moves upward relative to the upper clamping group. The upward movement of the upper clamping group is the upward movement of the upper clamping plate 510 and the upper driving member 530. The upward movement of the upper clamping plate 510 drives the upper end of the main panel 110 to move upward. At this time, if the main panel 110 is arranged obliquely, during the upward movement of the mounting shell 400, the upper end of the main panel 110 will move in the first direction relative to the lower end 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 is first rotated from the inclination to the verticality, and at this time, the second elastic member 523 and the upper clamping group remain relatively stationary.

[0032] When the main panel 110 is rotated to the verticality, during the continuous upward movement of the mounting shell 400, the tension on the lower end of the main panel 110 keeps the lower end of the main panel 110 stationary. At this time, the main panel 110 is rotated to the verticality, and the main panel 110 as a whole has no activity allowance. The upper clamping group located at the upper end of the main panel 110 also remains stationary. The mounting shell 400 moves upward relative to the upper clamping group. The first elastic member 522 continues to be stretched and compresses the second elastic member 523. The calibration process and principle of the single-layer panel 200 are the same as those of the main panel 110, and are not described herein. For the main panel 110 and the single-layer panel 200, when the inclination degrees of the two are different, the adjustment plate 521 in the test part 500 and the adjustment plate 521 in the control part 600 will have a height difference in the vertical direction until the main panel 110 and the single-layer panel 200 are both rotated from the inclination to the verticality. During this process, the elastic force generated by the compression of the second elastic member 523 will be evenly distributed by the uniform force rod 580, so that the whole detection device remains stable.

[0033] During the upward movement of the mounting shell 400, the two clamping blocks 570 in the same clamping piece can move close to each other in the second direction, so that the clamping space gradually becomes smaller. After the main panel 110 and the single-layer panel 200 are both adjusted to the verticality, the main panel 110 and the single-layer panel 200 are clamped again at the same position, so that the clamping positions of the upper ends of the main panel 110 and the single-layer panel 200 are consistent, and the detection result accuracy is further improved.

[0034] In a further embodiment, the upper transmission member 530 comprises a first transmission plate 531 and a second transmission plate 532, the first transmission plate 531 and the second transmission plate 532 are arranged side by side in the second direction, the first transmission plate 531 and the second transmission plate 532 are both in sliding fit with the adjusting plate 521, and the second transmission plate 532 is connected with the first transmission plate 531 through two first insertion blocks 533, a third elastic member is arranged between the first insertion block 533 and the first transmission plate 531, the third elastic member is arranged along the second direction, and the third elastic member is a spring. The third elastic member always has a tendency to move the second transmission plate 532 along the second direction to the side close to the first transmission plate 531. The two plate bodies of the upper clamping plate 510 are both provided with a first matching groove 512, the first matching groove 512 and the first insertion block 533 are arranged one by one, the first matching groove 512 is an arc groove, the first insertion block 533 is an arc block, the first insertion block 533 and the first matching groove 512 arranged correspondingly are in sliding fit, and the two first matching grooves 512 and the two first insertion blocks 533 are concentric, so that the two plate bodies of the upper clamping plate 510 can rotate relative to the first transmission plate 531 and the second transmission plate 532 around the second direction.

[0035] Further, the adjusting plate 521 comprises a main plate 524 and two auxiliary plates 525, the first elastic member 522 connects the main plate 524 and the mounting shell 400, the two auxiliary plates 525 are both installed at the lower end of the main plate 524, and one of the two auxiliary plates 525 is fixedly connected with the main plate 524, and the other auxiliary plate 525 is in sliding connection with the main plate 524 and can slide relative to the main plate 524 in the second direction. The first transmission plate 531 and the second transmission plate 532 are respectively in sliding fit on the two auxiliary plates 525.

[0036] By making one of the auxiliary plates 525 in sliding connection with the main plate 524, the main panel 110 and the single-layer panel 200 of different thicknesses can be adapted, of course, when the thicknesses of the clamped main panel 110 and single-layer panel 200 are fixed, the two auxiliary plates 525 can also be both fixedly connected with the main plate 524.

[0037] In a further embodiment, the lower transmission member 550 comprises two second insertion plates 551, the two second insertion plates 551 are arranged face to face in the first direction, the two second insertion plates 551 are both arc-shaped plates, a second insertion block 552 connects the second insertion plate 551 with the roller 560, and a fourth elastic member 553 is arranged between the second insertion block 552 and the roller 560, the fourth elastic member 553 is arranged along the second direction, the fourth elastic member 553 is a spring, and the fourth elastic member 553 always has a tendency to move the second insertion plate 551 along the second direction to the side close to the roller 560.

[0038] The two plate bodies of the lower clamping plate 540 are both provided with a second matching groove 541, and the second matching groove 541 is provided in one-to-one correspondence with the second plug block 552. The second matching groove 541 is an arc groove, and the second plug block 552 is an arc-shaped block. The second plug block 552 and the second matching groove 541 provided in correspondence therewith are in sliding fit, and the two second matching grooves 541 and the two second plug blocks 552 are concentric, so that the two plate bodies of the lower clamping plate 540 can rotate relative to the two second plug plates 551 in the second direction.

[0039] In a further embodiment, the first plug block 533 and the second plug block 552 are both provided with a plurality of rolling balls 554.

[0040] By providing the rolling balls 554, the friction between the first plug block 533 and the first matching groove 512 provided in correspondence therewith, and the second plug block 552 and the second matching groove 541 provided in correspondence therewith is reduced.

[0041] In a further embodiment, the drum 560 is provided with a flange at both ends, and a winding belt 561 is provided around the two flanges. In the initial state, the free end of the winding belt 561 is fixedly installed on the test bench 300 and kept tensioned.

[0042] When the main panel 110 is adjusted, the mounting shell 400 will drive the main panel 110 to move upward as a whole. At this time, the drum 560 rotates around its own axis while moving upward, and the winding belt 561 is elongated to adapt to the change in height. The drum 560 will gradually peel the main panel 110 from the core material 120 and wind it on the surface of the drum 560 until the test is completed.

[0043] In combination with the above embodiment, the specific working process is as follows: During detection, 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 with the upper clamping plate 510 and the lower clamping plate 540 provided in correspondence therewith in the test part 500, respectively. Then, the upper and lower ends of the single-layer panel 200 are connected with the upper clamping plate 510 and the lower clamping plate 540 provided in correspondence therewith in the control part 600, respectively. At this time, the main panel 110 and / or the single-layer panel 200 can be provided in an inclined manner relative to the vertical direction.

[0044] After driving the whole installation shell 400 to move up, taking the main panel 110 as an example, in the process of moving up of the installation shell 400, the installation shell 400 will drive the whole upper clamping group to move up through the first elastic member 522, and at this time the first elastic member 522 is stretched, the upper clamping group moves up relatively slower, that is, the installation shell 400 moves up relative to the upper clamping group. The upper clamping group moves up is that the upper clamping plate 510 and the upper driving member 530 move up, the upper clamping plate 510 moves up will drive the upper end of the main panel 110 to move up, at this time, if the main panel 110 is arranged obliquely, in the process of moving up of the installation shell 400, the upper end of the main panel 110 will move in the first direction relative to the lower end and swing around the second direction, and 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 is first rotated from the oblique to the vertical, and at this time, the second elastic member 523 and the upper clamping group remain relatively stationary.

[0045] When the main panel 110 is rotated to the vertical, in the process of continuing to move up of the installation shell 400, the pulling force on the lower end of the main panel 110 will keep the lower end of the main panel 110 stationary, at this time, the main panel 110 is rotated to the vertical, the main panel 110 as a whole has no activity allowance, the upper clamping group located at the upper end of the main panel 110 also remains stationary, the installation shell 400 moves up relative to the upper clamping group, the first elastic member 522 continues to stretch and compresses the second elastic member 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. And for the main panel 110 and the single-layer panel 200, when the oblique degrees of the two are different, the adjusting plate 521 in the test part 500 and the adjusting plate 521 in the control part 600 will have a height difference in the vertical direction until the main panel 110 and the single-layer panel 200 are both rotated from the oblique to the vertical. In this process, the elastic force generated by the compression of the second elastic member 523 will be evenly distributed by the uniform force rod 580, so that the whole detection device remains stable.

[0046] And in the process of moving up of the installation shell 400, the two clamping blocks 570 in the same clamping member can move close to each other in the second direction, so that the clamping space gradually becomes smaller, and after the main panel 110 and the single-layer panel 200 are both adjusted to the vertical, the main panel 110 and the single-layer panel 200 are clamped again at the same position, so that the clamping positions of the upper ends of the main panel 110 and the single-layer panel 200 are consistent, further improving the accuracy of the detection result.

[0047] When the main panel 110 is adjusted, the installation shell 400 will drive the whole main panel 110 to move up, at this time, the roller 560 moves up while rotating around its own axis, and the elongated belt 561 is wound, to adapt to the change of height, and the roller 560 will gradually separate the main panel 110 from the core material 120 and wind it on the surface of the roller 560, until the test is completed.

[0048] The above merely provides the preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
