Description

Technical Field

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

[0002] Currently, testing the tensile and shear properties of sealants requires sample preparation. Existing techniques typically involve two rectangular substrates of equal width, bonded together with sealant. Specifically, sample preparation involves first applying uncured sealant to one substrate as a sealant layer. This sealant layer has a certain length and is the same width as the substrate, with one end flush with the substrate. Then, the two substrates are aligned according to the length of the sealant layer and manually pressed together until the sealant layer thickness reaches the designed value. Once the sealant layer has cured, a sample can be formed. Then, the sample is stretched along its length to test the tensile shear strength and adhesive properties of the sealant. However, when using the above preparation method, it is difficult to control the sealant layer when the two substrate boards are manually pressed together. Furthermore, since the substrate boards themselves have manufacturing errors, it is even more inconvenient to control the thickness of the sealant layer. As a result, the thickness of the sealant layer in the sample will deviate from the design value, which will ultimately affect the test results. Therefore, there are still shortcomings and deficiencies in the existing technology.

[0003] Therefore, a tooling for preparing structural adhesive tensile bonding specimens is needed to solve the above problems. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the technical problems mentioned in the background section, some embodiments of this application provide a structural adhesive tensile bonding specimen preparation fixture, comprising: a base, on which a first limiting block and a second limiting block are slidably disposed, the first limiting block and the second limiting block being arranged opposite to each other; a lower side plate, slidably disposed on the base and located below the second limiting block; a first limiting groove, having multiple sets evenly distributed on the first limiting block; a second limiting groove, having multiple sets evenly distributed on the second limiting block, the first limiting groove and the second limiting groove being arranged opposite to each other; and a first substrate plate, on which a substrate plate is placed. The first limiting groove is placed inside the second limiting groove; the second base plate is placed inside the second limiting groove; multiple sets of second rubber pads are fixedly installed on the lower side plate, and the second rubber pads are embedded in the second limiting block; a vertically extending guide rail is fixedly installed on the base; an installation groove is opened on the lower side plate, and the installation groove slides with the guide rail, so that the lower side plate slides up and down on the base; a rotating screw that passes through the second limiting block is threadedly connected to the second limiting block, and a dovetail block is rotatably connected to one end of the rotating screw; a dovetail groove that extends back and forth is opened on the lower side plate, and the dovetail block is embedded in the dovetail groove and slides with the dovetail groove.

[0006] Furthermore, the second limiting block is provided with a sliding groove extending in the front-to-back direction, and a guide rail extending in the front-to-back direction is fixedly provided on the base. The guide rail slides in conjunction with the sliding groove. A positioning screw is threadedly connected to the second limiting block. One end of the positioning screw extends into the sliding groove and abuts against the guide rail to limit the second limiting block.

[0007] Furthermore, the base is provided with a vertically extending guide groove, and the first limiting block is fixedly provided with a guide protrusion that slides into the guide groove. The first limiting block is threadedly connected with a rotating screw, one end of which is rotatably connected to the base. By rotating the rotating screw, the first limiting block moves up and down.

[0008] Furthermore, a pressure plate is installed on the first limiting block, and a first rubber pad embedded in the first limiting groove is fixedly installed on the pressure plate. A screw hole is opened on the first limiting block, and a bolt is installed on the pressure plate. One end of the bolt is screwed into the screw hole to install the pressure plate.

[0009] Furthermore, a vertical plate is fixedly connected to the second limiting block, and one end of the first base plate abuts against the vertical plate for positioning.

[0010] Furthermore, the base is provided with scale lines, which are used to indicate the position of the second limit block.

[0011] Furthermore, a scale is provided on the guide convex edge. When the lower end wall of the first limiting groove is flush with the upper end wall of the second limiting groove, the starting position of the scale is directly opposite the upper plane of the guide groove.

[0012] The beneficial effects of this application are as follows:

[0013] 1. By setting the first limiting block and the second limiting block, when the first substrate board is placed into the first limiting groove, the lower end face of the first substrate board is in close contact with the lower end wall of the first limiting groove. At the same time, when the second substrate board is placed into the second limiting groove, the upper end face of the second substrate board abuts against the upper end wall of the second limiting groove under the action of the lower side plate and the second rubber pad. At this time, the thickness of the adhesive layer can be adjusted by controlling the horizontal distance between the lower end wall of the first limiting groove and the upper end wall of the second limiting groove.

[0014] 2. By using the guide rail and sliding groove, the distance between the vertical plate and the first limiting block can be controlled when the second limiting block is adjusted back and forth. When preparing the sample, the size of the adhesive area can be controlled by abutting one end of the first substrate plate against the vertical plate. Attached Figure Description

[0030] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] Reference Figure 1-6A structural adhesive tensile bonding specimen preparation fixture includes: a base 10, a first limiting block 11, a second limiting block 20, a pressure plate 15, a first limiting groove 12, a second limiting groove 22, a first substrate plate 13, a second substrate plate 14, a second rubber pad 30, a guide rail 31, and a mounting groove 32. The first limiting block 11 is vertically slidably disposed on the base 10 (i.e., sliding along the Z-axis direction). The base 10 has uniformly distributed first limiting grooves 12 that extend in the front-to-back direction (i.e., the Y-axis direction). The first limiting groove 12 has a lower end wall. When the first substrate plate 13 is placed in the first limiting groove 12, the lower end face of the first substrate plate 13 is attached to the lower end wall of the first limiting groove 12. At this time, the lower end face of the first substrate plate 13 and the lower end wall of the first limiting groove 12 are in the same plane. A lower side plate 25 that slides vertically is provided on the base 10. A second limiting block 20 that slides in the front-back direction is also provided on the base 10. The lower side plate 25 is located below the second limiting block 20. The second limiting block 20 and the first limiting block 11 are distributed front and back. Multiple evenly distributed and through second limiting grooves 22 are formed on the second limiting block 20, and the second limiting grooves 22 correspond one-to-one with the first limiting grooves 12. Multiple second rubber pads 30 embedded in the second limiting grooves 22 are fixedly connected to the lower side plate 25. When the second substrate plate 14 is inserted into the second limiting groove 22, the second substrate plate 14 is pushed to abut against the upper wall of the second limiting groove 22 by the second rubber pads 30. At this time, the upper surface of the second substrate plate 14 abuts against the upper wall of the second limiting groove 22, and the upper surface of the second substrate plate 14 and the upper wall of the second limiting groove 22 are on the same plane. When preparing the sample, the lower end face of the first substrate plate 13 is partially glued to the upper end face of the second substrate plate 14 and then pressed together. The distance between the lower end face of the first limiting groove 12 and the upper end face of the second limiting groove 22 is the thickness of the adhesive layer.

[0032] Multiple sets of second rubber pads 30 are fixedly installed on the lower side plate 25. The second rubber pads 30 are embedded in the second limiting block 20. A vertically extending guide rail 31 is fixedly installed on the base 10. An installation groove 32 is opened on the lower side plate 25. The installation groove 32 is slidably engaged with the guide rail 31, so that the lower side plate 25 can slide up and down on the base 10. A rotating screw 28 is threadedly connected to the second limiting block 20. One end of the rotating screw 28 is rotatably connected to a dovetail block 27. A dovetail groove 26 extending front and back is opened on the lower side plate 25. The dovetail block 27 is embedded in the dovetail groove 26 and slidably engaged with the dovetail groove 26.

[0033] The second limiting block 20 has a sliding groove 24 extending in the front-to-back direction. The base 10 is fixedly provided with a guide rail 23 extending in the front-to-back direction. The guide rail 23 slides with the sliding groove 24. The second limiting block 20 is threaded with a positioning screw 29. One end of the positioning screw 29 extends into the sliding groove 24 and abuts against the guide rail 23 to limit the second limiting block 20.

[0034] The base 10 has a vertically extending guide groove 19. The first limiting block 11 has a guide protrusion 18 that slides within the guide groove 19. A rotating screw 34 is threaded onto the first limiting block 11. One end of the rotating screw 34 is rotatably connected to the base 10. Rotating the rotating screw 34 causes the first limiting block 11 to move up and down. A pressure plate 15 is installed on the first limiting block 11. A first rubber pad 17 is fixedly installed on the pressure plate 15 and embedded within the first limiting groove 12. The first limiting block 11 has a screw hole. A bolt 16 is installed on the pressure plate 15. One end of the bolt 16 is screwed into the screw hole to install the pressure plate 15.

[0035] A vertical plate 21 is fixedly connected to the second limiting block 20, and one end of the first substrate plate 13 abuts against the vertical plate 21 for positioning. Similarly, one end of the second substrate plate 14 abuts against the first limiting block 11. By adjusting the front and rear position of the second limiting block 20, the size of the overlapping area between the first substrate plate 13 and the second substrate plate 14 can be adjusted. A scale line 33 is provided on the base 10 to indicate the position of the second limiting block 20.

[0036] The guide flange 18 is provided with a scale. When the lower end wall of the first limiting groove 12 is flush with the upper end wall of the second limiting groove 22, the starting position of the scale is directly opposite the upper plane of the guide groove 19. When there is a gap between the lower end wall of the first limiting groove 12 and the upper end wall of the second limiting groove 22, the gap between the lower end wall of the first limiting groove 12 and the upper end wall of the second limiting groove 22 can be determined by observing the position of the scale on the guide flange 18. It should be noted that when the lower end wall of the first limiting groove 12 is flush with the upper end wall of the second limiting groove 22, the upper end of the guide flange 18 is also flush with the upper end of the first limiting block 11. When high-precision measurement is required, the difference in elevation between the upper end surface of the guide flange 18 and the upper end surface of the first limiting block 11 can also be measured using a dial indicator to measure the gap between the lower end wall of the first limiting groove 12 and the upper end wall of the second limiting groove 22.

[0037] Teflon layers are attached to the inner walls of the first limiting groove 12 and the second limiting groove 22 to prevent glue from sticking.

[0038] Working process or usage method:

[0039] 1. Apply glue to the upper surface of the second substrate board 14 and insert it into the second limiting groove 22. Then, by rotating the rotating screw 28, the dovetail block 27 drives the lower side plate 25 and the second rubber pad 30 to move closer to the first limiting block 11, so that the second rubber pad 30 presses the lower surface of the second substrate board 14 to ensure that the upper surface of the second substrate board 14 is tightly attached to the upper wall of the second limiting groove 22.

[0040] 2. By observing the scale line 33, control the position of the second limiting block 20 so that one end of the second substrate plate 14 abuts against and is attached to the first limiting block 11.

[0041] 3. Then, by placing the first substrate plate 13 into the first limiting groove 12 and abutting one end against the vertical plate 21, and by installing the pressure plate 15, the lower end face of the first substrate plate 13 is pressed against the lower end wall of the first limiting groove 12 under the action of the first rubber pad 17. Then, the rotating screw 34 is rotated as a whole, so that the first limiting groove 12 moves downward, driving the first substrate plate 13 to move downward and gradually approach the second substrate plate 14. The thickness of the adhesive layer is controlled by observing the scale on the guide flange 18.
