Description

Technical Field

[0001] This utility model relates to the field of adhesive force testing technology, and in particular to a device for testing the adhesive force between rubber and metal. Background Technology

[0002] Adhesion testing devices, as key equipment for evaluating the adhesion strength between materials or coatings, play an irreplaceable role in many fields such as packaging, manufacturing, and scientific research. Especially in the testing of the adhesion performance of rubber and metal, the test results are directly related to the structural stability and safety of the product. For example, the quality control of products such as automotive seals and industrial pipe connectors depends on this.

[0003] Traditional adhesive strength testing methods have many limitations, severely restricting their testing effectiveness. On the one hand, these methods largely rely on manual operation to complete the sample clamping, positioning, and testing process. Due to factors such as uneven control of manual force and differences in operating rhythm, test data deviations are easily caused, making it difficult to guarantee accuracy and significantly reducing repeatability, thus hindering the formation of stable and reliable evaluation conclusions. On the other hand, some testing devices use robotic arms to hold the samples, which reduces manual intervention to some extent. However, robotic arms are expensive to manufacture and maintain, significantly increasing the overall investment in the testing process. This cost pressure is particularly prominent for small and medium-sized manufacturing enterprises or research institutions, making it difficult to achieve efficient cost control.

[0004] These issues directly impact the efficiency of production and scientific research. Low-precision and low-repeatability test results may lead to misjudgments of material bonding performance, thereby causing potential product quality problems. Meanwhile, high equipment costs limit the widespread application of testing devices, making it difficult to meet the high-frequency, low-cost testing needs of large-scale production. Therefore, given the unique characteristics of rubber-metal bonding force testing, it is urgent to improve traditional testing devices. By simplifying the operation process and reducing reliance on expensive robotic arms, testing costs can be reduced while improving accuracy and efficiency, better adapting to the needs of production practice and scientific research.

[0022] The present invention will be further described in detail below with reference to embodiments:

[0023] like Figure 1 , Figure 2The diagram shows a structural schematic of a rubber-metal adhesion force testing device, including a main unit 1 at the bottom. The main unit 1 has a trapezoidal platform shell and contains multiple motors (specifically four in this embodiment) arranged in a rectangular pattern. Each motor's output end is connected to a vertically upward lifting screw 11. A mounting plate 12 is mounted on the four lifting screws 11. Four screw holes are located at the four corners of the mounting plate 12. The internal thread of each screw hole matches the external thread of the lifting screw 11, with each screw hole engaging one screw. When the four lifting screws 11 rotate, the mounting plate 12 can be raised and lowered on the screws. A clamping device is located at the top of the main unit 1, between the four lifting screws, and a similar clamping device is located at the bottom of the mounting plate 12, with the two clamping devices positioned opposite each other, one above the other.

[0024] The specific structure of the clamping device is as follows: Figure 3 , Figure 4As shown, the clamping device specifically includes a connecting shaft 13, which is connected to the top of the main unit 1. The connecting shaft 13 has a hollowed-out sliding cavity, and a fixing hole is provided on the side wall of the sliding cavity. A sliding shaft 23, adapted to the sliding cavity, is also provided. The sliding shaft 23 can slide into the sliding cavity. A fixing hole is also provided on the side of the sliding shaft 23. When the two fixing holes are aligned, a removable stabilizing rod 22 can be inserted into both fixing holes simultaneously to fix the sliding shaft 23 and the connecting shaft 13. During routine maintenance, the stabilizing rod 22 can be removed for quick disassembly, facilitating rapid daily maintenance and repair of the components. Through the above structure and the use of quick-disassembly components, the device can be quickly and modularly disassembled, reducing the time cost of daily maintenance and repair and increasing the practicality of the device. A clamping groove 14 is fixedly provided on the sliding shaft 23. The clamping groove 14 is a square groove with a certain thickness on both sides and threaded holes. Each threaded hole on the side wall is fitted with an inward clamping bolt 2. The clamping bolt 2 and the threaded hole are meshed and can be screwed in and out by rotation. When the clamping bolts on both sides are rotated at the same time, metal or rubber can be clamped by the bolts themselves when they are close together in the middle. In order to improve the clamping effect, two clamping plates 21 are provided inside the clamping groove 14. The clamping plates 21 are parallel to the side walls of the clamping groove 14. The clamping plates 21 can be movable free plates, which are fixed only when the clamping bolts 2 are locked. The clamping plates 21 can also be movably set on the bottom surface of the clamping groove 14 through a sliding slider. Specifically, the bottom surface of the clamping groove 14 can be provided with a small-opening groove, that is, the width of the groove is greater than the opening of the groove. It can be a convex groove. A wide slider is provided at the bottom of the clamping plate 21, and the slider is locked in the groove. As the clamping bolts 2 on both sides are tightened and move towards the center, the clamping bolts 2 push against the clamping plates 21, causing the two clamping plates 21 to move towards the center, clamping the metal or rubber. The connection structure of the clamping device on the mounting plate 12 is as follows: a fixed base 3 is provided at the top of the mounting plate 12, and a bolt 31 is rotatably connected through the screw hole inside the fixed base 3. The middle of the mounting plate 12 is hollowed out to fit the bolt, and the bolt 31 extends downward through the mounting plate 12. A connecting shaft 13 is provided at the bottom of the bolt. In this embodiment, the connecting shaft 13 is specifically designed with a threaded blind hole at the bottom, and the bolt engages and penetrates into the blind hole to achieve fixation. A sliding shaft, clamping groove, and other devices are provided through the connecting shaft 13. The bolt 31 can be rotated to disconnect the bolt 31 from the connecting shaft 13 at the bottom of the mounting plate 12, and then the connecting shaft 13 at the bottom of the mounting plate 12 can be quickly removed, facilitating quick maintenance and repair of the components.

[0025] At the top of the main unit 1, a protective cover 4 is provided around the four lifting screws 11. The protective cover 4 covers and encloses the mounting plate 12 and the lifting screws 11, effectively reducing damage during daily use or storage and increasing the service life of the device. A top plate 41 is provided on top of the protective cover 4, which can limit the position of the mounting plate 12. Through the above structure, the addition of protective and limiting components provides stable protection for the main components of the device, increasing the service life of the device and improving its practicality and durability.

[0026] A central control unit 5 is fixedly mounted on the top of the main unit 1, located on the side of the protective cover 4. The central control unit 5 connects to the various motors inside the main unit 1, and all wiring converges to it. This allows for rapid control of the device, solving the problem of traditional testing devices requiring external control components and improving the device's overall integration. This structure integrates the central control unit with the device, resolving the need for an external control group during operation and enhancing the device's overall integrity. The main unit 1's outer shell is a trapezoidal platform, with a control block 6 fixedly mounted on the inclined sidewall of the trapezoid. A stop button 61 and a start button 62 are fixedly mounted on the control block 6. The internal wiring of the main unit 1 is connected to the stop button 61 and the start button 62 to control power on and off. The start button 62 controls the device's start and stop, and the stop button 61 controls its operation and stop. This structure, with its quick-access control buttons, makes device control faster and more convenient. Four support bases 7 are located at the four corners of the bottom of the main unit 1, forming a stable support and further improving the device's stability during operation.

[0027] During operation, the mounting plate 12 is close to the top of the main unit, and the two clamping devices are close together. After the rubber and metal are bonded together, the rubber is fixed to the lower clamping device, and then the metal is fixed to the upper clamping device. The main unit 1 is started, and the motor begins to work, driving the lifting screw 11 to rotate, which in turn drives the mounting plate 12 to rise, causing the upper clamping device to rise as well. The two clamping devices then separate and cooperate to test the adhesion force of the bonded rubber and metal. This application allows for rapid adhesion force testing, reducing testing time, improving the working efficiency of the device, and increasing its practicality. Furthermore, by incorporating quick-release components, the device allows for rapid component removal, enabling quick installation of test pieces and routine maintenance.

[0028] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
