Description

Technical Field

[0001] This utility model relates to the field of copper-aluminum composite plate technology, and in particular to a high-efficiency test device for peel strength of copper-aluminum composite plates with adjustable speed sliding locking. Background Technology

[0002] Copper-aluminum composite panels are a new type of composite material that combines two different metals, copper and aluminum, through a specific process. They possess excellent electrical and thermal conductivity, as well as high strength and corrosion resistance, making them widely used in electronics, power, and communications. Testing the peel strength of copper-aluminum composite panels is one of the important indicators for evaluating their quality and performance. The peel strength test mainly involves applying a certain tensile force to the copper and aluminum layers of the composite panel and observing the force required for the copper-aluminum interface to separate under specific conditions. Accurate peel strength testing helps manufacturers understand the bonding performance of their products, providing a basis for product improvement and optimization. It also provides users with a reliable quality reference when selecting and using copper-aluminum composite panels.

[0003] In current copper-aluminum composite panel peel strength testing scenarios, existing testing devices have some shortcomings. For example, in the quality inspection process of some copper-aluminum composite panel production workshops, traditional testing devices often can only perform tests at two specific angles: 90 degrees and 180 degrees. This results in a single testing angle, failing to comprehensively understand the peel performance of copper-aluminum composite panels at different angles. Because in actual use, copper-aluminum composite panels are subjected to forces from different directions, the test results from a single angle cannot accurately reflect their performance under complex usage environments. Moreover, when adjusting the testing angle, traditional testing devices typically require disassembling the clamping device and moving it to another preset position. This method is not only cumbersome and wastes time and manpower, but also damages the testing device during disassembly and installation, affecting the accuracy and stability of the test. Therefore, this art proposes an adjustable-speed sliding locking high-efficiency peel strength testing device for copper-aluminum composite panels to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an adjustable speed sliding locking high-efficiency test device for peel strength of copper-aluminum composite plates, which aims to improve the problems of limited switchable angles and inconvenient adjustment in the peel test of copper-aluminum composite plates in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency peel strength testing device for copper-aluminum composite plates with adjustable speed sliding locking, comprising a test frame and two positioning components. A hydraulic cylinder is installed on the top of the test frame, and an adjustment platform is fixedly connected to the inner side of the test frame. The adjustment platform has an internal movable groove, and a mounting base is slidably connected to the top of the adjustment platform. The two positioning components are respectively installed at the output end of the hydraulic cylinder and the top of the mounting base. An angle adjustment component is provided on the outer side of the adjustment platform, which is used to adjust the peel test angle of the copper-aluminum composite plate.

[0006] The deflection angle adjustment assembly includes a rack plate, one side of which is fixedly connected to the outside of the mounting base. A sliding plate is fixedly connected to the bottom of the mounting base. Multiple round holes are opened inside the sliding plate and the inside of the test bench. A locking rod is installed inside the test bench. Two spring telescopic rods are fixedly connected to the top of the test bench. One end of the two spring telescopic rods is fixedly connected to a rack plate. An electric push rod is installed inside the test frame.

[0007] Furthermore, the outer side of the sliding plate is slidably connected to the inner side of the movable groove, and the outer side of the first rack plate is in contact with the outer side of the second rack plate.

[0008] Furthermore, one end of the locking rod is slidably connected to the inner side of two of the circular holes, and a rubber ring is fixedly connected to the outer side of the locking rod.

[0009] Furthermore, the output end of the electric actuator is fixedly connected to the outer side of the mounting base, and a handle is fixedly connected to the outer side of the rack plate II.

[0010] Furthermore, the positioning assembly includes mounting heads, one end of each of the two mounting heads being respectively mounted on the output end of the hydraulic cylinder and the top of the mounting base, and a rotating rod being rotatably connected to the outer side of each mounting head.

[0011] Furthermore, a stud is fixedly connected to the outer side of the rotating rod, and an assembly head is threadedly connected to the outer side of the stud.

[0012] Furthermore, two clamping blocks are slidably connected to the inner side of the assembly head, and the inner side of the clamping blocks is rotatably connected to one end of the stud.

[0013] Furthermore, a sliding rod is fixedly connected to the outer side of the clamping block, and two limiting grooves are opened inside the assembly head. The outer side of the sliding rod is slidably connected to the inner side of the limiting groove.

[0014] This utility model has the following beneficial effects:

[0015] In this invention, the mounting base is moved by activating the electric actuator, and with the cooperation of multiple structures, the mounting base can precisely move a fixed unit of one tooth. According to the pre-designed tooth size, the copper-aluminum composite plate can be flexibly stretched to various angles for testing. Compared with the traditional method of only testing at 90 degrees and 180 degrees, this method offers more options and makes adjusting multiple test levels more convenient and faster. Compared with the traditional method of directly disassembling the clamping device and moving it to another preset position for operation, this method is obviously more convenient and efficient.

[0016] In this invention, rotating the rotating rod moves the assembly head, causing the slide bar to slide along the inner side of the inclined limiting groove. This causes the two clamping blocks to move closer together, tightly clamping the end of the copper-aluminum composite plate. The outer side of the clamping blocks is provided with reverse teeth, which greatly enhances the clamping force on the end of the copper-aluminum composite plate, making it more stable. This clamping helps with the subsequent peel strength test, ensuring that the copper-aluminum composite plate will not loosen during the test. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-3This utility model provides an embodiment of a high-efficiency peel strength testing device for copper-aluminum composite plates with adjustable speed sliding locking. The device includes a test frame 1 and two positioning components. The test frame 1 serves as the main structure of the entire device, providing stable support for other components. A hydraulic cylinder 2 is mounted on the top of the test frame 1, providing strong pulling force for peel testing of the copper-aluminum composite plate. A test bench 3 is fixedly connected to the inner side of the test frame 1, providing a stable platform for subsequent testing operations. A movable groove 4 is provided inside the test bench 3, providing space for the movement of a mounting base 5. The mounting base 5 is slidably connected to the top of the test bench 3, allowing it to... The test angle of the copper-aluminum composite plate is adjusted by sliding on the test bench 3. Two positioning components are respectively installed at the output end of the hydraulic cylinder 2 and the top of the mounting base 5. The positioning components are used to fix both ends of the copper-aluminum composite plate to ensure that the copper-aluminum composite plate will not loosen during the test. An angle adjustment component is provided on the outside of the test bench 3. The angle adjustment component is used to adjust the peel test angle of the copper-aluminum composite plate. The angle adjustment component includes a rack plate 6. One side of the rack plate 6 is fixedly connected to the outside of the mounting base 5 and moves with the movement of the mounting base 5. A sliding plate 7 is fixedly connected to the bottom of the mounting base 5. The sliding plate 7 slides in the movable groove 4 of the test bench 3, providing guidance for the movement of the mounting base 5. Both the interior of the test stand 7 and the interior of the test stand 3 have multiple round holes 8. These round holes 8 are used to insert locking rods 9 to fix the position of the mounting base 5. The interior of the test stand 3 is equipped with locking rods 9, which can be inserted into the round holes 8 to fix the mounting base 5 in a specific position. The top of the test stand 3 is fixedly connected to two spring telescopic rods 12. The spring telescopic rods 12 can provide elastic force to reset the rack plate 13. One end of the two spring telescopic rods 12 is fixedly connected to the rack plate 13. The rack plate 13 and the rack plate 6 cooperate with each other to achieve precise movement of the mounting base 5. The inner side of the test stand 1 is equipped with an electric push rod 11, which provides power for the movement of the mounting base 5. The outer side of the sliding plate 7 is... The mounting base 5 is slidably connected to the inner side of the movable groove 4 to ensure smooth movement. The outer side of the rack plate 1 6 fits against the outer side of the rack plate 2 13. When the electric push rod 11 pushes the mounting base 5 to move, the rack plate 1 6 and the rack plate 2 13 interact to achieve precise movement of the mounting base 5. One end of the locking rod 9 is slidably connected to the inner side of the two round holes 8. A rubber ring 10 is fixedly connected to the outer side of the locking rod 9. The rubber ring 10 can increase the friction between the locking rod 9 and the round holes 8, making the position of the mounting base 5 more stable. The output end of the electric push rod 11 is fixedly connected to the outer side of the mounting base 5. A handle 14 is fixedly connected to the outer side of the rack plate 2 13. The handle 14 makes it convenient for the operator to pull the rack plate 2 13.

[0024] Specifically, after the copper-aluminum composite plate is securely clamped, the electric actuator 11 can be activated to move the mounting base 5. When the mounting base 5 begins to move, the rack plate 13, which is in contact with the rack plate 6, will be subjected to a compressive force. As the mounting base 5 continues to move, this force will gradually cause the rack plate 13 to separate from the inclined surface of the rack plate 6, until the rack plate 6 and the rack plate 13 are misaligned by one tooth. At this point, due to the elastic force of the two spring telescopic rods 12, the rack plate 13 will be quickly reset and re-engage with the outer side of the rack plate 6. In this way, the mounting base 5 can be precisely positioned... Move the tooth by one tooth, and then insert the locking rod 9 into the round hole 8. This will fix the position of the mounting base 5. According to the pre-designed tooth size, the copper-aluminum composite plate can be flexibly stretched to various angles for testing. Compared with the traditional method of only testing at 90 degrees and 180 degrees, this method offers more options. Moreover, the adjustment of multiple test levels is more convenient and faster. Compared with the traditional method of directly disassembling the clamping device and moving it to another preset position for operation, this method is obviously more convenient and efficient. The sliding speed of the mounting base 5 can be adjusted by pushing the electric push rod 11.

[0025] Reference Figures 1-3 The positioning assembly includes mounting heads 15, with one end of each head 15 mounted on the output end of the hydraulic cylinder 2 and the top of the mounting base 5, respectively. The mounting heads 15 provide a mounting base for other components of the positioning assembly. A rotating rod 16 is rotatably connected to the outer side of each mounting head 15. The rotating rod 16 can be rotated to adjust the position of the assembly head 18. A stud 17 is fixedly connected to the outer side of the rotating rod 16, rotating with the rotation of the rotating rod 16. The assembly head 18 is threadedly connected to the outer side of the stud 17, allowing the assembly head 18 to move on the stud 17. The inner side of the assembly head 18 slides... The assembly head 18 has two clamping blocks 19. The clamping blocks 19 are used to clamp the ends of the copper-aluminum composite plate. The inner side of the clamping block 19 is rotatably connected to one end of the stud 17. When the stud 17 rotates, the clamping block 19 can slide inside the assembly head 18. The outer side of the clamping block 19 is fixedly connected to a slide rod 20. The slide rod 20 provides guidance for the movement of the clamping block 19. The assembly head 18 has two limiting grooves 21. The outer side of the slide rod 20 is slidably connected to the inner side of the limiting groove 21. The limiting groove 21 restricts the range of movement of the slide rod 20, thereby ensuring that the clamping block 19 can accurately clamp the ends of the copper-aluminum composite plate.

[0026] Specifically, the two ends of the copper-aluminum composite plate can be placed inside the two clamping blocks 19 in the two positioning components. Then, the rotating rod 16 is rotated. The rotation of the rotating rod 16 causes the assembly head 18 to move. During this process, the limiting groove 21 inside the assembly head 18 restricts the sliding rod 20, causing the sliding rod 20 to slide only along the inside of the inclined limiting groove 21. As the sliding rod 20 slides, the two clamping blocks 19 move closer together, ultimately clamping the ends of the copper-aluminum composite plate tightly. It is worth noting... Yes, the outer side of the clamping block 19 is provided with reverse teeth. These reverse teeth can greatly enhance the clamping force on the end of the copper-aluminum composite plate, making it more stable. Such stable clamping helps with the subsequent peel strength test, ensuring that the copper-aluminum composite plate will not loosen during the test. Then, the hydraulic cylinder 2 is activated, and the hydraulic cylinder 2 will pull the upper positioning component upward. Under this pulling force, the copper-aluminum composite plate will be gradually peeled off. By measuring and analyzing the force applied by the hydraulic cylinder 2, the peel strength data of the copper-aluminum composite plate can be obtained.

[0027] Working principle: First, the two ends of the copper-aluminum composite plate can be placed inside the two clamping blocks 19 in the two positioning components. Then, the rotating rod 16 is rotated to move the position of the assembly head 18, thereby limiting the sliding rod 20 by the limiting groove 21, causing the sliding rod 20 to slide along the inner side of the inclined limiting groove 21, thereby bringing the two clamping blocks 19 closer together and clamping the ends of the copper-aluminum composite plate. The outer side of the clamping block 19 is provided with reverse teeth, which can hold the ends of the copper-aluminum composite plate firmly, which helps in the subsequent peel strength test. Then, the hydraulic cylinder 2 is activated to pull the upper positioning component upward, so that the copper-aluminum composite plate can be gradually peeled off. The peel strength data of the copper-aluminum composite plate can be obtained based on the force applied by the hydraulic cylinder 2.

[0028] In addition, after the copper-aluminum composite plate is securely clamped, the electric actuator 11 can be activated to move the mounting base 5. When the mounting base 5 moves, the rack plate 13, which is in contact with the rack plate 1 6, will gradually separate from the inclined surface of the rack plate 1 6 under the pressure of compression until the rack plate 1 6 and the rack plate 13 are misaligned by one tooth. The rack plate 13 will then be reset by the elastic force of the two spring telescopic rods 12 and will once again be in contact with the outer side of the rack plate 1 6. This allows the mounting base 5 to move precisely by one tooth. Then, the locking rod 9 is inserted into the round hole 8 to fix the position of the mounting base 5. According to the pre-designed tooth size, the copper-aluminum composite plate can be flexibly stretched to various angles for testing. This provides more options than the traditional 90-degree and 180-degree tests, and the adjustment of multiple test gears is more convenient. It is also more convenient than the traditional method of directly disassembling the clamping device and moving it to another preset position for operation.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
