The tensile testing component includes a tensile tester body, a support frame on top of the tensile tester body, a tensile hook sensor on the top right side of the tensile tester body, a control panel on the right side of the tensile tester body, and a tensile clamping component, which includes a servo motor. This utility model, through the cooperative arrangement of the tensile testing component and the tensile clamping component, allows the transmission block to drive the first and second clamping blocks to move independently, thereby ensuring that the high-strength structural adhesive can be stably stretched upwards. This prevents operators from applying excessive or insufficient force during manual stretching, improves the stability and durability of the tensile tester, reduces maintenance requirements, extends the service life of the tensile tester, and thus improves the overall reliability of the tensile tester.

Description

Technical Field

[0001] This utility model relates to a tensile strength tester for high-strength structural adhesives, belonging to the technical field of high-strength structural adhesives. Background Technology

[0002] High-strength structural adhesives are adhesives with excellent properties such as high strength, high toughness, aging resistance, and corrosion resistance. They are widely used in construction, automotive, aerospace, and electronics industries.

[0003] Authorization Announcement No. (CN208795638U); This utility model discloses a high-strength structural adhesive tensile tester, including an adhesive assembly, a tensile gauge, and a tensile mechanism. The adhesive assembly consists of an adhesive component and a bonded component. The adhesive component is U-shaped, and the bonded component is located at the opening of the adhesive component, with its left and right ends bonded to the left and right sidewalls of the adhesive component via structural adhesive. The upper and lower ends of the tensile gauge are connected to the tensile mechanism and the bonded component respectively via connectors. The tensile mechanism includes a housing, a drive servo motor, a threaded sleeve, and a threaded rod. The output shaft of the drive servo motor is connected to gear one, which meshes with gear two. This high-strength structural adhesive tensile tester, by setting up a U-shaped adhesive component and a bonded component, better matches the stress mode of structural adhesive in actual applications, resulting in more representative test results. Furthermore, the use of the drive servo motor, threaded sleeve, and threaded rod in conjunction with the tester replaces manual pulling, saving manpower and reducing the labor intensity of workers.

[0004] However, the aforementioned tensile testing instrument may lack measures for automatically adjusting the tension of the clamping blocks during use. Usually, the operator performs manual stretching, which can easily lead to situations where the force is too strong or too weak, affecting the test results and requiring multiple tests. This, in turn, affects the overall stability and reliability of the tensile testing instrument and increases maintenance costs.

[0005] To address this, a high-strength structural adhesive tensile strength tester is proposed. Utility Model Content

[0029] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0030] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0031] Example 1

[0032] like Figure 1-6 As shown, this utility model embodiment provides a high-strength structural adhesive tensile strength tester, including:

[0033] The tensile testing assembly includes a tensile testing instrument body 1, a support frame 2 on the top of the tensile testing instrument body 1, a tensile hook sensor 3 on the top right side of the tensile testing instrument body 1, and a control panel 4 on the right side of the tensile testing instrument body 1.

[0034] The tension clamping assembly includes a servo motor 5, a first screw 6 at the output end of the servo motor 5, a transmission block 7 on the surface of the first screw 6, a first clamping block 8 on the right side of the transmission block 7, and a second clamping block 9 at the bottom of the first clamping block 8.

[0035] By using the coordinated setup of the tensile testing component and the tensile clamping component, the transmission block 7 drives the first clamping block 8 and the second clamping block 9 to move independently, thereby ensuring that the high-strength structural adhesive can be stretched upward stably. This prevents operators from applying excessive or insufficient force when manually stretching the adhesive, improves the stability and durability of the tensile tester, reduces maintenance requirements, and extends the service life of the tensile tester, thus improving the overall reliability of the tensile tester.

[0036] Example 2

[0037] like Figure 1-6As shown, in one embodiment, the tension clamping assembly further includes a guide rod 10, which is fixedly connected to the bottom of the support frame 2. The guide rod 10 passes through the transmission block 7 and is slidably connected to the transmission block 7. It also includes an adjustment assembly, which includes a rotating block 11, a second screw 12 located on the left side of the rotating block 11, and a connecting block 13 located on the surface of the second screw 12. The adjustment assembly also includes a groove 14, which is formed on the left side of the inner wall of the first clamping block 8. The left side of the second screw 12 is movably connected to the inner wall of the groove 14 via a bearing. It also includes a support assembly, which includes a slide bar 15, a moving groove 16 on the right side of the second clamping block 9, and anti-slip texture 17 on the surface of the rotating block 11. The anti-slip texture 17 is used in conjunction with the rotating block 11. A slider 18 is fixedly connected to the top of the connecting block 13. A sliding groove 19 is opened on the top of the inner wall of the first clamping block 8. The slider 18 is used in conjunction with the sliding groove 19. A limiting block 20 is fixedly connected to the bottom of the first screw 6. The cross-sectional area of ​​the limiting block 20 is larger than that of the first screw 6. The limiting block 20 is used in conjunction with the transmission block 7.

[0038] The guide rod 10 provides auxiliary positioning for the transmission block 7, preventing it from rotating during movement. The adjustment component allows for adjustment of the position of the second clamping block 9, enabling it to work in conjunction with the first clamping block 8. The groove 14 accommodates the bearing portion of the second screw 12, preventing it from occupying a large area. The support component provides auxiliary support for the second clamping block 9, preventing it from tilting during movement. The anti-slip texture 17 facilitates easier rotation of the rotating block 11, improving user comfort.

[0039] In operation, the high-strength structural adhesive sample is placed between the first clamping block 8 and the second clamping block 9. The rotating block 11 is connected to the second screw 12. Rotating the rotating block 11 drives the second screw 12 to rotate. The second screw 12 is movably connected to the groove 14 in the first clamping block 8 through a bearing. The connecting block 13 is threadedly engaged with the second screw 12 and moves linearly when the second screw 12 rotates. The connecting block 13 is connected to the second clamping block 9. Therefore, rotating the rotating block 11 can adjust the position of the second clamping block 9. The second clamping block 9 and the first clamping block 8 close together to clamp and fix the high-strength structural adhesive. Then, the servo motor 5 is started, which drives the first screw 6 to rotate. The first screw 6 is threadedly connected to the transmission block 7, which drives the transmission block 7 to move linearly on the surface of the first screw 6. The transmission block 7 drives the first clamping block 8 and the second clamping block 9 to move upward. Through the precise control of the servo motor 5, the stable movement of the first clamping block 8 and the second clamping block 9 can be achieved, thereby applying a stable tensile force to the sample.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
