Description

Technical Field

[0001] This utility model relates to the field of honeycomb panel testing technology, specifically to a honeycomb panel impact testing device. Background Technology

[0002] Honeycomb panels are a sandwich structure consisting of two high-strength panels and a lightweight honeycomb core. They combine excellent rigidity, strength, and lightweight advantages, while also possessing outstanding thermal insulation, sound insulation, and energy absorption characteristics. They are widely used in aerospace, transportation, building curtain walls, and other fields with stringent requirements for structural performance and weight. Impact testing of honeycomb panels is necessary because under external impact, the adhesive interface between the panels and the honeycomb core may experience localized debonding, core collapse, or even microscopic cracks or indentations that are difficult to see with the naked eye. These hidden damages not only reduce the bending, shear, and compressive strength of the panels but may also rapidly expand under repeated loads, thereby weakening the overall load-bearing capacity and shortening the service life.

[0003] Existing impact testing devices mostly use free fall: First, in order to obtain sufficient impact energy, a tall free fall frame must be built, which occupies a lot of space in the laboratory or workshop and is time-consuming to install and debug; second, when adjusting the impact energy, the height of the free fall or the weights need to be changed, which is cumbersome and difficult to achieve controllable adjustment. To solve the above problems, we propose a honeycomb panel impact testing device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a honeycomb panel impact detection device, solving the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A honeycomb panel impact testing device includes: a base plate, on the top surface of which a honeycomb panel body is disposed, an arc-shaped frame is fixedly installed on the top surface of the base plate, a testing groove is formed on the bottom surface of the arc-shaped frame, and the honeycomb panel body is located inside the testing groove; and an impact assembly disposed on the outer wall of the arc-shaped frame for impact testing.

[0007] By adopting the above technical solution, an impact component is set up to impact the honeycomb panel body for testing. At the same time, the impact force can be controlled, avoiding the shortcomings of existing equipment that uses free fall, which occupies a lot of laboratory space and requires changing the fall height or weights to adjust the impact energy, resulting in cumbersome operation.

[0008] Preferably, the impact assembly includes: an arc-shaped hole, the arc-shaped hole being formed on the outer wall of the arc-shaped frame, the arc-shaped hole being connected to the detection groove, an inner block being provided inside the arc-shaped hole, and an impact head being fixedly installed on one side of the inner block.

[0009] By adopting the above technical solution and setting an impact head, the inner block can move within the arc-shaped hole during use, and the impact head can strike the honeycomb panel body for testing.

[0010] Preferably, the impact assembly further includes: two side grooves, which are respectively opened on the left and right sides of the arc-shaped hole. Arc-shaped grooves are respectively opened on the top and bottom surfaces of the side grooves. A spring is provided between the two arc-shaped grooves. Side plates are fixedly installed on the left and right sides of the inner block, and the side plates are sleeved together with the side grooves. The side plates are fixedly connected to the springs.

[0011] By adopting the above technical solution and setting a spring, the inner block can be moved within the arc-shaped hole during use, thereby compressing the spring. After the inner block is released, the spring's reset will push the inner block to move along the arc-shaped hole, causing the impact head to strike the honeycomb panel body. The arc-shaped trajectory design ensures sufficient impact stroke while significantly reducing the vertical height and space occupation of the device. At the same time, precise control of impact energy can be achieved by only finely adjusting the initial position of the inner block in the arc-shaped hole.

[0012] Preferably, the impact assembly further includes: two external holes, both of which are formed on the inner wall of the arc-shaped hole, the external holes communicating with the adjacent arc-shaped groove, and a connecting rope sleeved inside the external holes, the connecting rope being fixedly connected to the side plate by passing through the spring.

[0013] By adopting the above technical solution and setting a connecting rope, it is easy for users to pull the inner block and move it along the arc-shaped hole, so that the spring can contract and achieve precise control of the impact energy.

[0014] Preferably, the impact assembly further includes: two bearing seats, both bearing seats are fixedly installed on the top surface of the base plate, a winding wheel is fixedly installed between the two bearing seats, the winding wheel is fixedly connected to the connecting rope, and a first handwheel is fixedly installed at one end of the winding wheel.

[0015] By adopting the above technical solution and setting a first handwheel, the winding wheel can be rotated during use to drive the winding connecting rope to pull the inner block, thus increasing convenience.

[0016] Preferably, the top and bottom surfaces of the side plate are respectively provided with inner grooves, and the inner grooves are connected to rolling balls. The top and bottom surfaces of the inner side grooves are respectively provided with sliding grooves, and the sliding grooves are in contact with the adjacent balls.

[0017] By adopting the above technical solution and setting ball bearings, the frictional resistance of the side plate in the side groove can be reduced during use through the fit between the ball bearings and the sliding groove. This not only improves the response speed during impact, but also provides a smooth guide for the winding and unwinding of the connecting rope.

[0018] Preferably, threaded holes are provided on the left and right sides of the detection groove, and bolts are threaded into the internal threads of the threaded holes. Two clamping plates are provided inside the detection groove. A rotating bearing is embedded in one side of the clamping plate. The rotating bearing is fixedly connected to the bolt. A second handwheel is fixedly installed on one side of the bolt.

[0019] By adopting the above technical solution and setting up a clamping plate, the second handwheel can be rotated during use to drive the clamping plate to stably hold the honeycomb panel body through the cooperation of bolts and threaded holes, thereby increasing the stability during subsequent testing.

[0020] Preferably, an anti-slip pad is fixedly installed on the top surface of the base plate.

[0021] In summary, the present invention has the following main advantages:

[0022] By setting up an impact component for testing the honeycomb panel body, the impact force can be controlled, avoiding the shortcomings of existing equipment that uses free fall, which occupies a lot of laboratory space and requires changing the fall height or weights to adjust the impact energy, resulting in cumbersome operation. By setting up an impact head, the inner block can move within the arc-shaped hole during use, and the impact head impacts the honeycomb panel body for testing.

[0023] By incorporating a spring, the inner block can be moved within the arc-shaped hole during use, compressing the spring. Once the inner block is released, the spring's return causes it to move along the arc-shaped hole, driving the impact head to strike the honeycomb panel. The arc-shaped trajectory design ensures sufficient impact travel while significantly reducing the device's vertical height and space requirements. Furthermore, precise control of the impact energy can be achieved simply by fine-tuning the initial position of the inner block within the arc-shaped hole. A connecting rope allows users to easily pull the inner block along the arc-shaped hole, causing the spring to contract and thus achieving precise control of the impact energy.

[0024] By setting a first handwheel, the winding wheel can be rotated during use to wind up the connecting rope and pull the inner block, increasing convenience. By setting ball bearings, the contact between the ball bearings and the sliding groove reduces the frictional resistance of the side plate in the side groove, which not only improves the response speed during impact, but also provides smooth guidance for the winding and unwinding of the connecting rope.

[0025] By setting up clamping plates, the second handwheel can be rotated during use to stably clamp the honeycomb panel body through the cooperation of bolts and threaded holes, thereby increasing the stability during subsequent testing. Attached Figure Description

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the present utility model embodiments clearer, the technical solutions of the present utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present utility model, but not all embodiments. All other embodiments obtained by those skilled in the art based on the described embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0032] refer to Figures 1-3A honeycomb panel impact testing device includes: a base plate 100, a honeycomb panel body 200 disposed on the top surface of the base plate 100, an arc-shaped frame 300 fixedly mounted on the top surface of the base plate 100, a detection groove 400 formed on the bottom surface of the arc-shaped frame 300, the honeycomb panel body 200 located inside the detection groove 400, and an impact component 500 disposed on the outer wall of the arc-shaped frame 300 for impact testing. By setting the impact component 500 to impact the honeycomb panel body 200 for testing, the impact force can be controlled, avoiding the use of free fall method in existing equipment. The defect impact component 500, which is cumbersome to operate and requires changing the drop height or weights when adjusting the impact energy, occupies a large amount of laboratory space. It includes an arc-shaped hole 501, which is opened on the outer wall of the arc-shaped frame 300 and is connected to the detection slot 400. An inner block 502 is set inside the arc-shaped hole 501. An impact head 503 is fixedly installed on one side of the inner block 502. By setting the impact head 503, it can move within the arc-shaped hole 501 through the inner block 502 during use, and the impact head 503 impacts the honeycomb panel body 200 for testing.

[0033] refer to Figures 1-3 The impact assembly 500 further includes: two side grooves 504, which are respectively formed on the left and right sides of the arc-shaped hole 501. Arc-shaped grooves 505 are formed on the top and bottom surfaces of the side grooves 504. A spring 506 is disposed between the two arc-shaped grooves 505. Side plates 507 are fixedly installed on the left and right sides of the inner block 502, respectively. The side plates 507 are sleeved with the side grooves 504 and fixedly connected to the springs 506. By setting the springs 506, during use, the inner block 502 can be moved within the arc-shaped hole 501, thereby compressing the springs 506. After releasing the inner block 502, the springs 506 can reset, pushing the inner block 502 to move along the arc-shaped hole 501. The impact head 503 impacts the honeycomb panel body 200. Due to its arc-shaped trajectory design, it ensures sufficient impact stroke while significantly reducing the vertical height and space occupation of the device. At the same time, precise control of impact energy can be achieved by only finely adjusting the initial position of the inner block 502 in the arc-shaped hole 501. The impact assembly 500 also includes two outer holes 508, both of which are opened on the inner wall of the arc-shaped hole 501. The outer holes 508 are connected to the adjacent arc-shaped groove 505. A connecting rope 509 is sleeved inside the outer hole 508. The connecting rope 509 passes through the spring 506 and is fixedly connected to the side plate 507. By setting the connecting rope 509, it is convenient for the user to pull the inner block 502 and move it along the arc-shaped hole 501, so that the spring 506 can be contracted to achieve precise control of impact energy.

[0034] refer to Figures 1-3The impact assembly 500 further includes: two bearing seats 510, both bearing seats 510 being fixedly installed on the top surface of the base plate 100; a winding wheel 511 being fixedly installed between the two bearing seats 510; the winding wheel 511 being fixedly connected to the connecting rope 509; a first handwheel 512 being fixedly installed at one end of the winding wheel 511; by setting the first handwheel 512, in use, rotating the first handwheel 512 can drive the winding wheel 511 to rotate, winding the connecting rope 509 and pulling the inner block 502, increasing convenience; and side plate 50. The top and bottom surfaces of the 7 are respectively provided with inner grooves 600, and the inner grooves 600 are connected with rolling balls 601. The top and bottom surfaces of the side grooves 504 are respectively provided with sliding grooves 602. The sliding grooves 602 are in contact with the adjacent balls 601. By setting the balls 601, the frictional resistance of the side plate 507 in the side groove 504 can be reduced during use through the contact between the balls 601 and the sliding grooves 602. This not only improves the response speed during impact, but also provides a smooth guide for the winding and unwinding operation of the connecting rope 509.

[0035] refer to Figures 1-3 The detection groove 400 has threaded holes 700 on its left and right sides, and bolts 701 are threadedly connected inside the threaded holes 700. Two clamping plates 702 are provided inside the detection groove 400. A rotating bearing 703 is embedded in one side of the clamping plate 702. The rotating bearing 703 is fixedly connected to the bolts 701. A second handwheel 704 is fixedly installed on one side of the bolts 701. By setting the clamping plates 702, the second handwheel 704 can be rotated during use, and the clamping plates 702 can be stably clamped by the cooperation of the bolts 701 and the threaded holes 700, thereby increasing the stability during subsequent testing. An anti-slip pad 800 is fixedly installed on the top surface of the base plate 100.

[0036] Working principle: Please refer to Figures 1-3 As shown, during use, the honeycomb panel body 200 to be tested is placed in the testing groove 400. By rotating the second handwheel 704, the clamping plate 702 stably clamps the honeycomb panel body 200 through the cooperation of the bolt 701 and the threaded hole 700. Then, by rotating the first handwheel 512, the winding wheel 511 is rotated to wind up the connecting rope 509, thereby compressing the spring 506. Afterwards, the spring 506 is reset, pushing the inner block 502 to move along the arc-shaped hole 501, causing the impact head 503 to impact the honeycomb panel body 200. Due to the arc-shaped trajectory design, sufficient impact stroke is ensured while significantly reducing the vertical height and space occupation of the device. At the same time, only the initial position of the inner block 502 in the arc-shaped hole 501 needs to be finely adjusted to achieve precise control of the impact energy. The contact between the ball bearing 601 and the sliding groove 602 reduces the frictional resistance of the side plate 507 in the side groove 504, which not only improves the response speed during impact but also provides a smooth guide for the winding and unwinding operation of the connecting rope 509.
