Description

Technical Field

[0001] This application relates to the field of specimen preparation tooling, and more specifically, to a tooling for rapid preparation of structural adhesive tensile specimens. Background Technology

[0002] The tensile test of structural adhesives involves applying tensile force to a sample bonded with structural adhesive. The sample typically consists of two substrates bonded together with structural adhesive. The preparation of the test sample is quite demanding. The two substrates must be overlapped on coaxial parallel surfaces by applying structural adhesive. The length of the bonding surface and the thickness of the adhesive layer must be controlled within the range of 12.5±0.25mm and 0.2mm, respectively. The control of the bonding dimensions is quite strict. Furthermore, the adhesive is fluid and requires 1-3 hours to cure. Manual fixing is inefficient and of low quality, which restricts the application of testing parameters for structural adhesives.

[0003] Existing sample preparation devices, such as the patent document with announcement number CN222579748U, disclose a sample preparation device for testing the shear strength of structural adhesives. The device includes a base and a fixing screw. A screw support is fixedly connected to the base, and multiple fixing screws are threaded at equal intervals on the screw support. A cleaning groove is provided on the base, and edge baffles are fixedly provided on the opposite two sides of the base. Multiple partitions are vertically and equidistantly fixedly connected to the edge baffles, and adjacent partitions form processing slots of the same size. The structural adhesive sample to be bonded is placed in the processing slot, and the cleaning groove is located below the bonding surface of the structural adhesive sample.

[0004] However, the above-mentioned device requires rotating multiple fixing screws to press the test piece to make the sample. After the sample is made, the multiple fixing screws need to be loosened, which is a relatively complicated operation. Therefore, a tooling for rapid preparation of structural adhesive tensile test specimens is needed to solve the above problems. Utility Model Content

[0026] Reference Figure 1-6A rapid preparation fixture for structural adhesive tensile specimens includes: a base 10, a lifting seat 11, a support platform 33, a first placement groove 16, and a second placement groove 21. The lifting seat 11 is slidably mounted on the base 10 and located at the front side of the base 10, while the support platform 33 is fixedly mounted on the base 10 and located at the rear side of the lifting seat 11. Multiple evenly distributed first placement grooves 16 are formed on the lifting seat 11, and a first substrate 14 is placed in each of the first placement grooves 16. Multiple evenly distributed second placement grooves 21 are formed on the support platform 33, and a second substrate 15 is placed in each of the second placement grooves 21. During specimen preparation, the lower surface of one end of the first substrate 14 is bonded to the upper surface of one end of the second substrate 15. A guide post 17 is fixedly mounted on the base 10, passing through the lifting seat 11, and the lifting seat 11 is slidably engaged with the guide post 17. A threaded rod 18 is rotatably mounted on the base 10, passing through the lifting seat 11, and the threaded rod 18 is threadedly engaged with the lifting seat 11. By rotating the threaded rod 18, the lifting seat 11 is moved up and down.

[0027] In one embodiment, when bonding the first substrate 14 and the second substrate 15, it is necessary to press the first substrate 14 and the second substrate 15 together. This is achieved by detachably installing a first cover plate 12 on the lifting seat 11. The first cover plate 12 covers the upper side of the lifting seat 11, and a plurality of first rubber pads 19 are fixedly connected to the first cover plate 12. The first rubber pads 19 are respectively embedded in the first placement groove 16. The first cover plate 12 is installed on the lifting seat 11 by bolts. After the first cover plate 12 is installed, the first rubber pads 19 abut against the upper side of the first substrate 14, pressing the first substrate 14 tightly into the first placement groove 16.

[0028] In one embodiment, a support platform 22 is provided on the base 10, located on one side of the bearing platform 33. The upper surface of the support platform 22 is flush with the bottom wall of the second placement groove 21. After the second substrate 15 is placed into the second placement groove 21, one end of the second substrate 15 is flush with one side of the support platform 22. At this time, the support platform 22 supports the underside of the adhesive portion of the second substrate 15. Teflon is attached to the support platform 22 for easy cleaning of the adhesive later. The dimensions of the support platform 22 are consistent with the dimensions of the adhesive area of ​​the sample. Therefore, when one end of the second substrate 15 is flush with one side of the support platform 22, the adhesive area is the upper area of ​​the support platform 22.

[0029] In one embodiment, a sliding groove 26 extending through the second placement groove 21 is provided on the side wall. A sliding block 27 is slidably disposed within the sliding groove 26. A sliding rod 25, passing through and fixedly connected to multiple sliding blocks 27, is disposed between the sliding blocks 27. The sliding rod 25 has a portion passing through the second placement groove 21. An mounting sleeve 28, located within the second placement groove 21, is fitted onto the sliding block 27. A torsion spring 32 connects the mounting sleeve 28 and the sliding rod 25, with both ends of the torsion spring 32 fixedly connected to the mounting sleeve 28 and the sliding rod 25, respectively. A connecting rod 29 is fixedly connected to the mounting sleeve 28, and a sponge head 30 is detachably mounted on one end of the connecting rod 29. Under the action of the torsion spring 32, the sponge head 30 rests against the lower side wall of the second placement groove 21. A threaded head is provided at one end of the connecting rod 29, and the sponge head 30 is threadedly mounted to one end of the connecting rod 29 through the threaded head. When the sponge head 30 needs to be replaced, it can be unscrewed and replaced by lifting the sponge head 30.

[0030] Second rotating heads 35 are rotatably mounted at both ends of the sliding rod 25. One end of the hinge rod 31 is fixedly connected to the second rotating head 35. First rotating heads 34 are rotatably mounted on both sides of the support platform 33. A rotating rod 24 is mounted on the first rotating head 34, and a hinge rod 31 is hinged to the rotating rod 24. One end of the hinge rod 31 is fixedly mounted on the sliding rod 25. When the push handle 23 is pushed forward, the sliding rod 25 and the sliding block 27 move forward, thereby driving the sponge head 30 to move forward. The sponge head 30 wipes and cleans the upper surface of the second substrate 15 placed in the second placement groove 21.

[0031] To prevent the second substrate 15 from slipping during wiping and cleaning, a second cover plate 13 is bolted to the support platform 33. Multiple second rubber pads 20 are evenly distributed on the second cover plate 13. After the second cover plate 13 is installed on the support platform 33, the second rubber pads 20 are embedded in the second placement groove 21 to press and fix the second substrate 15.

[0032] Working process or usage method: 1. When preparing the sample, first place the second substrate 15 in the second placement groove 21 so that one end of the second substrate 15 is flush with the support platform 22. Install the second cover plate 13 on the support platform 33 and press and limit the second substrate 15. By pushing the push handle 23, the sliding rod 25 and the sliding block 27 are pushed forward under the action of the hinge rod 31, which in turn pushes the sponge head 30 to move, so that the sponge head 30 moves back and forth to wipe and clean the upper surface of the second substrate 15 to avoid affecting the adhesive strength. 2. After cleaning, apply structural adhesive to the upper surface of the second substrate 15, and then place the cleaned first substrate 14 in the first placement groove 16. The first substrate 14 is limited by installing the first cover plate 12 on the lifting seat 11. One end of the first substrate 14 is flush with one end of the lifting seat 11. At this time, the adhesive area meets the standard of the sample. 3. By rotating the threaded rod 18, the lifting seat 11 is driven to move downward, so that the lower surface of the first substrate 14 is bonded to the upper surface of the second substrate 15.
